Changelog

Easy Invoice follows semantic versioning loosely — MAJOR.MINOR.PATCH where MAJOR is reserved for breaking schema changes (rare).

Easy Invoice (free) — 2.4.0 — September 11, 2026

• Added — Server-side PDF rendering. PDFs are now real text documents (~25 KB for a page instead of a ~180 KB screenshot), rendered identically for every client. The in-browser method remains as a fallback.
• Added — PDF attached to invoice emails (optional, off by default): Settings → Email → General.
• Added — Credit notes. Issued invoices can no longer be edited or permanently deleted; a credit note (CN-…) corrects them, in part or in full, with a printed reason. See Payments → Refunds and credit notes.
• Added — Statement of account per client, on screen and as PDF, with running balance and balance brought forward.
• Added — VIES check for EU VAT numbers on the invoice builder.
• Added — REST API (easy-invoice/v1): invoices, quotes, clients, PDF download — gated by the same capabilities as the admin screens.
• Added — Per-line tax categories, VAT identities and reverse-charge handling underneath, which the Pro E-Invoicing addon builds on.
• Added — Import from Sliced Invoices, Sprout Invoices and CSV: clients, quotes, invoices with every line, and payments; numbers and dates kept, existing clients reused, running twice adds nothing.
• Added — Viewed tracking: each invoice and quote records when the client first and last opened it, shown in the lists and returned by the REST API; easy_invoice_document_viewed fires on the first view.
• Added — Attachments on invoices and quotes, from the media library — listed on the page and PDF and sent with the email.
• Added — Hooks underneath the new Pro addons: a signature pad on the public quote page, easy_invoice_quote_accepted with the acceptance details, easy_invoice_text_setting for saved labels, easy_invoice_email_template_data / easy_invoice_email_finished around every email, easy_invoice_reports_after_summary on the Reports page.
• Fixed — A PayPal payment verified by IPN left the invoice unpaid until someone marked it by hand. The verified payment now completes the record and settles the invoice; IPN retries are ignored.
• Fixed — Deleting a client no longer fails; the confirmation count matches what is removed, and payments are kept as accounting records.
• Fixed — Guest customers and per-invoice tax settings are persisted even when the site's global tax is off.
• Changed — The public invoice and quote pages are real WordPress pages now, and themes can override every template by copying it to {theme}/easy-invoice/…. See Hooks & filters → Frontend templates. Bank transfer / cheque / cash payment from an emailed link, which failed with "Invalid invoice", works again.
• Changed — All third-party scripts (jsPDF, html2canvas, Chart.js) ship inside the plugin instead of loading from CDNs; the admin stylesheet is purged from 2.9 MB to 47 KB.
• Fixed — The invoice and quote builders could not add a line item (the row's markup printed as text); CSV exports carried HTML entities; the Pro licence screen and Template Builder canvas rendered as text.
• Changed — Download as PDF captures the page exactly as shown again (browser), with a setting to use a server-generated file instead; server-generated PDFs now reproduce the selected design (every built-in design and Pro Template Builder canvases) rather than one neutral layout, with a plain layout available under Settings → Email.
• Fixed — An invoice to a person without a business name showed no name in the To block; the PDF now honours renamed Subtotal / Tax / Discount labels and shows Paid and Balance due when money has been received.
• Fixed — Team Roles works. EI Manager / Accountant / Sales / Viewer can open the screens their capabilities name; the sidebar and list controls follow the role; WooCommerce no longer bounces team members to My Account.
• Fixed — Add New Payment records money received (cash, cheque, bank transfer, other) and settles the invoice, instead of running the customer checkout and failing. Partially paid invoices are labelled.
• Fixed — Settings screen field ids (every image field was id "0"), unstyled amber/emerald notices across the admin, lists scrolling sideways at 1440 px, dashboard/report figures (active clients, payment time, top clients), broken report links, a fatal on the payment view, the builder's "Edit client" link with no client, payment-panel icons.
• Added — Client Portal settings (Settings → Client Portal): pick or create the portal page with one click, auto-create client logins. The portal greets clients by name and lists date · amount · status.
• Changed — WooCommerce, E-Invoicing, Payment Links, Quote Forms and Translations screens rebuilt on Pro's addon page pattern; Translations sits in the sidebar while Client Language is on; the raw "Pro Settings" screen is retired. Item Library no longer saves every item twice; Time Tracking accepts any number of hours.
• Added — Every invoice design shows Total Due in its header and Paid / Balance due under the total once money has come in; multi-page PDFs carry a page label.
• Fixed — Removing the last attachment did not persist; quote-to-invoice conversion produced nameless zero lines; a logo that fails to load left a broken-image icon.
• Changed — Every design reset, one by one. Standard is ink on white with one rule per section; Classic keeps its dark serif ledger row without the cell grid; Minimal / Minimalist are hairlines only (Minimalist centres its header); Modern and Professional lose the panel-inside-a-panel header and heavy shadows; Legacy keeps its ruled grid with softer rules. A small "INVOICE" / "QUOTE" line sits above every document title.
• Changed — Every design tidied and three made distinct. Corporate has a navy masthead and total, Elegant a serif with hairlines and a bronze total, Creative one gradient and striped rows (they were one layout in three colours). All designs align numeric headings over the figures, use tabular numbers, print totals without colons, and show the client's contact person, phone and VAT number plus your own tax ID in the header; an empty "To" block is left out. Legacy invoices print Terms & Conditions; server PDFs of every design fit a two-line invoice on one page. Filters: easy_invoice_client_block_html, easy_invoice_tax_id_label.
• Fixed — The Reports page's Invoice Report showed most invoices at $0.00 and every one as "Unpaid" (it read meta a saved invoice never has, ignored the date range and counted trashed invoices); it now uses the documents' real totals and statuses, with a Partially paid bucket, and the status chart draws when its tab opens.
• Fixed — in emails used the site's name instead of the business name from Settings → Company.
• Fixed — A part-paid or credited invoice asked for the full amount again. What is owed is one figure everywhere now — total less payments and credit notes: the Total Due in every design, a "Credit note CN-…" row and Balance due in the totals (page, PDF, email attachment), the payment panel ("Amount Due", and that is what a gateway charges), Pay Now shown while anything is owed; an unpaid invoice credited in full is cancelled; a reversed payment no longer sends an issued invoice back to Draft.
• Fixed — "Overdue" and "Expired" are derived states now: an invoice still owed after its due date reads Overdue in lists, filters, the dashboard and the client page (the tiles counted statuses nothing sets, so they read 0); the quote expiry check targeted a post type that does not exist, so quotes never expired — open quotes past their date are expired, and an expired, accepted or declined quote cannot be accepted or declined again.
• Changed — Stock emails rewritten as plain business correspondence with a "View and pay" button and an placeholder; sites still on the old stock text are moved over once. Receipts go out for every payment (instalments included) with the right amount, method, date and balance remaining — they used to print and only after full payment.
• Changed — Money is formatted one way everywhere (payment panel, statements, dashboard, reports); a separate Line total label for the item table; statements name payments by method.
• Fixed — Trashing marked a paid invoice cancelled and restoring made it Available; an invoice comes back from the trash with the status it had. The Draft tab lists drafts (it listed everything); "Move to draft" is refused for paid or part-paid invoices and the bulk actions match the row actions. Quote and invoice models gained real getMeta() / setMeta() methods — the old calls silently did nothing, which several Pro addons had relied on.
• Fixed — POST /easy-invoice/v1/invoices now creates a real invoice: it used to leave the status blank, skip the client record and fire none of the creation hooks. It takes client_id, customer_name/customer_email, currency, terms and an optional draft/available status; invoice responses carry totals.paid, totals.credited and totals.due. The API reference now documents the REST routes (it said there were none).
• Fixed — Removing a payment left the invoice "Paid": trashing, restoring or deleting a payment on the Payments screen now re-checks the invoice against its remaining payments and credit notes. A quote's acceptance and decline details (date, who, reason) are stored, and a client reopening a closed quote is told what happened. Adding a client with a taken email says why. The Reports overview's status chart uses the same derived statuses as the list and honours the date range.
• Upgrading from 2.3.x — links emailed before 2.4.0 carry no access token and show "not found" until re-sent (or keep the old behaviour with easy_invoice_require_document_authorisation); issued invoices lock and are corrected with credit notes; theme overrides of the old single templates move to {theme}/easy-invoice/; update Pro to 2.3.0 alongside.

Easy Invoice Pro — 2.3.0 — September 11, 2026

• Added — E-Invoicing addon (Professional): Factur-X / ZUGFeRD PDF/A-3 and Peppol BIS 3.0 UBL for invoices and credit notes, validated against EN 16931 before a file is produced; reads incoming Factur-X, CII and UBL.
• Added — WooCommerce addon (Personal): an invoice for every order at a chosen status, payments recorded, refunds issued as credit notes, HPOS-compatible, Invoice link in My Account.
• Added — Card on file: with the client's consent on the Stripe form, recurring and subscription cycles are charged automatically. Off by default. Not yet exercised against a live Stripe account — watch the first live charge.
• Added — Quote Forms (Personal): a WPForms, Gravity Forms, Contact Form 7 or Fluent Forms submission opens a draft quote or invoice with the client already created.
• Added — Quote E-Signatures (Personal): accepting a quote means signing it; the signature is printed on the quote, its PDF and the converted invoice.
• Added — Payment Links & QR Codes (Personal): a link or QR code for a fixed or open amount; an invoice is created for the payer on the spot.
• Added — Retainers & Prepayments (Professional): a prepayment balance per client, applied to invoices by hand or automatically.
• Added — Client Language (Professional): each client's documents and emails in their own language; the Translations page now offers your saved labels and email text per language.
• Added — Profit & loss on the Reports page: payments against expenses month by month, net, margin, CSV export.
• Added — Webhooks: invoice.viewed and quote.viewed events.
• Fixed — The Translations page did not work (posted to an unregistered settings group, read values nothing wrote, no import/export handlers). Rebuilt.
• Fixed — The client portal was a blank page on block themes (every default WordPress theme since 2022): the portal forced a page.php those themes do not have. Pro Template Builder and PDF Toolkit watermarks now appear on server-generated PDFs (email attachments, API).
• Fixed — Pro did not run on PHP 7.4 (two PHP 8 union types were parse errors); the build now checks every file with PHP 7.4.
• Fixed — Secure links switched themselves off on every admin request because the addon watched a mis-spelled option key; restored where the addon is enabled. A secure link can now pay, accept and decline, and the redirect from a plain permalink keeps its query arguments.
• Fixed — Recurring invoices were numbered outside the sequence ("NW-9" from "NW-000008"); generated invoices now take the next sequential number.
• Fixed — Partial Payments made a paid invoice's total read 0 to statements, credit notes, e-invoicing and the REST API; the total is the total again, the balance stays in the breakdown.
• Fixed — Stripe payments were booked twice on sites with the webhook configured, and a webhook on its own could never mark an invoice paid. One record per payment, whichever path arrives first.
• Security — The Stripe confirmation trusted the browser's invoice id; it now books only against the invoice in the PaymentIntent's own metadata.
• Fixed — Subscription invoices generated an invoice for nothing — no lines, no client, no number — and never charged anyone. Cycles are now built like recurring invoices, trial cycles bill the trial amount, and both flow through card on file.
• Fixed — Partial Payments' instalment form never appeared (a wrong class name in the hook, and a syntax error in its script). Card instalments now go to the gateway for that amount, with Stripe checking the amount server-side; offline instalments are recorded as pending and say so; a confirmed instalment marks the invoice Partially paid.
• Changed — Recurring invoices keep the parent's payment terms, the admin notice links to the generated draft, and the "every 2 minutes" test frequency is hidden outside WP_DEBUG.
• Fixed — The basic payment reminder never sent either (it read the client address with a method that does not see it, and chased statuses no sent invoice holds); it now sends, with the secure link and the amount still owed, in the branded layout. Quote watermarks follow the same rules as invoice ones (no stamp on a sent quote).
• Fixed — Smart Reminders never sent anything: it chased statuses a sent invoice never holds. It now covers available / partially paid / unpaid / overdue, sends only the latest due step to an invoice that is already long overdue (not all four at once), prints the real amount and a token-carrying secure link, and the late fee is actually added to the invoice and shown as a row.
• Fixed — Every document carried a diagonal "AVAILABLE" watermark by default: PDF Toolkit now defaults to no watermark, empty text means none, and the status stamp only marks paid / partially paid / unpaid / overdue / draft / cancelled (and accepted / declined / expired quotes).
• Fixed — Template Builder's element palette was hidden under the plugin sidebar and the sheet opened cut off; it now sits beside the sidebar and opens zoomed to fit.
• Added — Template Builder Data tab: render the canvas with one of your real invoices or quotes instead of sample data. Delete on the Webhooks, Time Tracking, Team Roles and White-Label pages asks for confirmation again (the dialog never loaded).
• Fixed — Client Portal actions refused the invoice's own client (the ownership check read a meta key nothing writes); view, download, pay and receipt links work. Quote pages get their watermark for browser PDFs. The payments CSV has its Client column. Legacy recurring code and admin templates nothing loaded are removed.
• Fixed — Email Enhancements had no settings anywhere (its fields were registered on a tab the plugin never rendered). Rebuilt with its own page: a Reply-To for all emails or per kind, and a custom email layout with a one-click test. White-Label's email and PDF footers work now (the filters were never applied); reminders go out with the From/Reply-To from Settings → Email instead of "WordPress".
• Fixed — Time Tracking and Expense Tracking drafts go through the invoice repository (business name, payment terms, numbering, hooks); clients are named properly; trashing or deleting the invoice frees the entries again. Item Library prices use the site's currency in the builder picker.
• Fixed — Webhook invoice.created / invoice.updated / quote.created bodies were empty (built before the invoice had saved its data); assembled at the end of the request now, with real quote status, customer and dates.
• Fixed — Deposit invoices: all three numbering modes work as labelled (suffix, prefix, sequence), the split dialog offers only real statuses, and the notes on both invoices are written for the client.
• Fixed — Template Builder element colours accept transparent and can be cleared (the colour picker forced black), items tables show item names saved by the builder, dates follow the site's date format, the logo element falls back to the business name, and the total block prints credit notes, Paid and Balance due.
• Fixed — Exports were mostly empty: Bulk Operations and the Export page read meta a saved invoice never has, so amounts, clients, statuses and dates came out blank and the filters matched nothing; they now export the documents' real figures with working client, status and issue-date filters (easy_invoice_pro_export_field_value to add columns).
• Fixed — The Client Portal's Download and Pay actions did nothing (they linked to handlers that no longer existed): Download streams the server PDF and Pay opens the invoice with the payment panel.
• Fixed — Privacy Tools exported nothing for a client and the eraser needed a WordPress user; the personal-data exporter now includes the client record, invoices, payments and quotes (matched by email as well as user), and erasure works for guest customers.
• Fixed — Webhook and accounting-sync payloads carried zero totals for normally saved invoices (they read a stored total that only credit notes and shop orders have); Xero, FreshBooks and QuickBooks payments, Paystack references and webhook bodies now use the documents' real totals, and invoice webhooks carry amount_due. payment.recorded fires for partial payments as well.
• Changed — The Pro zip now unpacks into an easy-invoice-pro/ folder, so uploading it through Plugins → Add New installs cleanly.
• Changed — The Pro zip carries its easy-invoice-pro/ folder again, so a renamed download still installs into the right folder.
• Fixed — The custom-PDF endpoint produces a real PDF (with the PDF Toolkit watermark) instead of HTML named .pdf.
• Security — Licence/update requests and the Moneris gateway now verify TLS certificates; the client-portal login goes through wp_signon() so throttling and 2FA apply; CSRF checks added to the CSV exports.
• Fixed — GDPR export/erasure returned nothing for every subject; Team Roles' audit logger could fatal on quote acceptance; Additional Tax was never applied to totals (a one-time notice appears on affected sites).

Easy Invoice (free) — 2.3.7 — June 29, 2026

• Fixed — Invoice and Quote listing "Download PDF" button could leave the user stranded on a blank admin-ajax.php?action=easy_invoice_generate_pdf… page instead of downloading the PDF. Root causes on affected sites included page-cache layers (WP Rocket, LiteSpeed, Cloudflare) replaying stale responses of the intermediate admin-ajax URL, security plugins / WAFs stripping the redirect body, and cross-tab session-cookie behaviour (Safari ITP, SameSite=Strict) dropping the WP session between the click and the new tab. Two coordinated changes address this:
  1. The button no longer routes through admin-ajax. The anchor's native href already points at <invoice-permalink>?auto_download_pdf=1, and the single-page JS renders the PDF from there. Removing the click interceptor collapses three server round-trips into one and sidesteps every intermediate-hop failure mode. No security posture change — the destination is the same public permalink the hop was going to anyway.
  2. The server-side download handlers are hardened for any external caller. generateInvoicePdf and generateQuotePdf now accept an admin session (manage_options) or a valid per-document access key (?ik= / ?qk=) as alternate authorisation paths when the per-request nonce fails, emit explicit Cache-Control: no-store headers to defeat intermediate caching, and fall back to a client-side redirect (<meta refresh> + window.location.replace()) when the server-side redirect can't fire because headers are already sent. Email download links, dashboard widgets, and any other integration calling these endpoints directly benefit from the same hardening.

Easy Invoice Pro — 2.2.6 — June 28, 2026

• Security — Twelve AJAX handlers in the Custom Templates addon (the Template Builder back-end) were previously gated by nonce only; they now also require admin capability (manage_options). The Template Builder UI is admin-only in practice — the change brings the previously-missing handlers to the same policy already enforced on the controller's other eight handlers. No customer-facing behaviour changes; admins continue to use the Template Builder exactly as before.

Easy Invoice (free) — 2.3.6 — June 26, 2026

• Security — Tightened the capability check on the AJAX payment-update endpoint so only users with the dedicated payment-management permission can change payment records or invoice status. All sites should update.
• Security — [easy_invoice_url] and [easy_quote_url] no longer mint per-document access keys for arbitrary visitors. Access keys are now produced exclusively when an invoice / quote email is sent; the shortcodes attach an existing key only when the current viewer is the site admin, the bound client, or already holds the key in the page URL.
• Fixed — Bound-client recognition on quote Accept / Decline and invoice manual-payment submission was a dead branch since 2.3.4: the guard used method_exists() which returns false for __call-resolved methods, and both Invoice and Quote resolve getClientId() that way. Logged-in clients whose email matches the document's bound client are now correctly authorised. (Admin and emailed-link paths were unaffected.)
• Note — Emailed and links continue to work unchanged for the legitimate recipient. The shortcode change is invisible for admin embeds on admin-context pages; on public pages the shortcode now renders a plain permalink for visitors who don't already hold a valid key.

Easy Invoice (free) — 2.3.5 — June 26, 2026

• Security — Hardened authorisation on the manual-payment submission flow (Bank Transfer / Cheque / Cash). The public AJAX endpoint now requires either a valid per-invoice access key, an admin session, or the bound client logged in by email match. All sites should update.
• Improved — Invoice share links sent via email merge tag and the [easy_invoice_url] shortcode now carry a per-invoice access key. Recipients of these links can submit manual-payment proof as before — no extra steps for the customer.
• Note — Invoice links generated before this update still load and pay through online gateways (Stripe / PayPal / etc.); only the "submit manual payment" form requires the new keyed link or a logged-in client whose email matches the invoice.
• Fixed — Race condition under high concurrency where two simultaneous invoice (or quote) creates could be assigned the same number. The counter read-check-write sequence is now serialised via a MySQL named lock; the lock auto-releases on connection close so it cannot leak across requests.
• Added — License recognition for the new Professional Lifetime and Agency Lifetime SKUs so customers on those tiers are placed correctly and see the matching variant label on the License page.

Easy Invoice Pro — 2.2.5 — June 26, 2026

• Security — Hardened authorisation on the Partial Payments AJAX endpoints (processPartialPayment, getPaymentHistory). Same ownership model as the Free plugin's manual-payment flow.
• Security — Webhooks outbound SSRF blocklist extended to explicitly cover Azure's IaaS metadata endpoint (168.63.129.16) and IPv4-mapped IPv6 representations of loopback and cloud-metadata addresses.
• Security — Square webhook replay protection. The handler records each event_id in a 24-hour transient and short-circuits replays so a captured signed webhook can't be re-fired to duplicate notifications or payment records.
• Security — Bulk-export endpoints (exportCSV, exportInvoicesCSV, exportQuotesCSV) now require admin capability (manage_options), matching the sibling "Export All" buttons that were already gated.
• Fixed — Recurring invoice next-run dates now respect the site timezone (WordPress Settings → General → Timezone) instead of falling back to the host's PHP date.timezone ini value. Existing schedules keep their stored next-run; the first recalculation after upgrade picks up the corrected logic.
• Fixed — Pro deactivation now clears all nine Pro-owned cron events instead of just the legacy payment-reminders hook. Previously, orphan cron registrations stayed in WordPress's cron queue indefinitely after Pro was deactivated.

Easy Invoice (free) — 2.3.4 — June 12, 2026

• Security — Hardened authorisation on the quote Accept and Decline flows. The public AJAX endpoints now require a per-quote access key, admin session, or bound-client email match (CVE-2026-9021).
• Improved — Quote share links emailed to clients (, [easy_quote_url]) now carry a per-quote access key.
• Note — Quote links generated before this update still display the quote, but Accept / Decline buttons require a new keyed link (admin resend), client login, or admin action.

Easy Invoice (free) — 2.2.0 — May 13, 2026

• Added — "Export Selected (Pro)" option in the Bulk Actions dropdown on both Invoice and Quote listings. Visible to all users; picking it without Pro opens the Upgrade-to-Pro dialog.
• Added — "Send Email (Pro)" option in the Bulk Actions dropdown on both listings (companion to the existing Pro bulk-send feature).
• Added — "Filter by client" dropdown on All Invoices and All Quotes listings. Persists across view tabs, status chips, pagination, and search.
• Added — "Documentation" link in the plugin sidebar (under Join Community) opening easy-invoice.matrixaddons.com/docs/.
• Added — "Unlock more payment gateways" teaser block on Settings → Payment when Pro is inactive (Stripe, Square, Authorize.Net, Mollie, Paystack, Moneris, Bank Transfer, Cheque, Cash).
• Improved — Pro-gated submit interceptors moved to native capture-phase listeners so they always run before the listing template's inline jQuery submit handlers. Fixes the generic "Confirm Action" race on the Quote listing.
• Fixed — Quote listing search form posted to a wrong page slug (easy-invoice-quotes-all → easy-quote-all); picking a value from the client filter no longer redirects to "you are not allowed".
• Fixed — Quote / Invoice client filter now uses the correct meta-key namespaces (_easy_invoice_client_id / _easy_invoice_quote_client_id) plus a fallback match on the client's customer_email. Filter now narrows the listing correctly for both flows.
• Fixed — Default Invoice / Quote email bodies no longer ship the literal [easy_(invoice|quote)_url …] shortcode-reference line that was emailed to clients as raw text. One-time migration strips the line from already-saved options.
• Internal — Documentation links across readme.txt and helpers now point to https://easy-invoice.matrixaddons.com/docs/ instead of the legacy URL.

Easy Invoice Pro — 2.2.0 — May 13, 2026

• Added — Paystack payment gateway. Hosted-checkout flow (card / bank / USSD / mobile money / QR) for African and select international merchants. Supports NGN, GHS, ZAR, KES, USD, EGP, XOF. HMAC-SHA512 signed-webhook verification; server-side /transaction/verify reconciliation on customer return.
• Added — Bulk Send Email. Tick rows on Invoice / Quote listing → "Send Email" → Apply. Pro dispatches the configured "Available" template to every selected document's client and reports a per-row success/failure toast.
• Added — Bulk Export Selected. Tick rows → "Export Selected" → Apply → confirm. Pro streams a UTF-8 CSV (with BOM for Excel) of just the selected rows. Endpoint admin-post.php?action=easy_invoice_pro_bulk_export, capability-gated, nonce-verified.
• Added — Extension hooks easy_invoice_paystack_payment_complete, easy_invoice_pro_after_bulk_send_email, easy_invoice_pro_after_bulk_export.
