## Description
**Easy Invoice** turns your WordPress site into your invoicing system. Create invoices
and quotes, send them as PDFs, take payment on the invoice page and keep every client’s
history in one place — with no per-document limits, no watermarks and no trial period.
It is built for freelancers, consultants, agencies and small businesses that would
rather not pay a monthly fee for a separate invoicing service, and for developers
who want invoicing that follows WordPress conventions: custom post types, capabilities,
hooks, a REST API and coding standards.

#### What the free plugin does
**Invoices and quotes**
* Unlimited invoices and quotes, with automatic numbering and your own prefix —
numbers stay unique even when two people save at the same moment
* Line items with quantities, per-line or global tax, and discounts calculated
before or after tax
* Convert an accepted quote into an invoice in one click; clone any document
* Credit notes against issued invoices; client statements with running balances
* Notes, terms, due dates and payment instructions per document; default terms
in Settings
**PDF and print**
* PDFs are rendered on the server (real, selectable text) with your logo and business
details
* Nine document designs: default, modern, classic, minimal, corporate, professional,
elegant, creative and legacy
* Rename any label (“Grand Total”, “Net”, your language) without touching code
* Download from the admin, from the public invoice page, or through the REST API
**Getting paid**
* PayPal checkout with a Pay Now button on every invoice
* Bank transfer, cheque and cash recorded against the invoice — clients can upload
proof of a transfer or cheque for you to approve
* Payment history with partial, paid and overdue states
* A custom Pay Now link for any other provider
**Clients**
* Unlimited client records with billing details and a complete per-client history
* Invoice and quote emails with the PDF attached, from templates you edit
* Every emailed link carries a private access key: a document is shown to you,
to the signed-in client it belongs to, or to someone with the emailed link —
never to whoever guesses a URL
* Import from Sliced Invoices or Sprout Invoices in one click, or from CSV files
with downloadable templates
**Localisation**
* 121 currencies, with symbol, position, decimals and separators set per document
* Dates in the site’s timezone; translation-ready (text domain `easy-invoice`)
* Multisite compatible
**For developers**
* REST API for invoices, quotes, clients and PDFs — [API reference](https://easy-invoice.matrixaddons.com/docs/api-reference)
* Migration from Sliced Invoices and Sprout Invoices built in
* Actions and filters at every step; documents are custom post types you can query
* WordPress coding standards, escaped output, prepared SQL, nonce-protected actions
* Tested with 10,000 invoices and 10,000 quotes on one site: every admin screen
stays under a second

#### Who uses Easy Invoice
* **Freelancers** — quote, invoice and collect payment from one screen
* **Agencies and studios** — per-client history, statements, deposits and a client
portal
* **Shops and B2B sellers** — proper invoices for WooCommerce orders and everything
the cart can’t bill
* **Consultants and service firms** — billed hours, expenses, retainers and e-invoices
for larger customers
#### Privacy
Easy Invoice stores everything in your own WordPress database and sends nothing
to us. The plugin contacts outside services only when you use them: the payment
gateway you configure (PayPal in the free plugin), and the WordPress.org update
check that every plugin performs. Card details never touch your site — they are
handled by the gateway. With the Pro Privacy & GDPR addon, a client’s invoices,
quotes and payments are included in WordPress’s personal-data export and erasure
requests.
#### Translations
Easy Invoice is translation-ready (text domain `easy-invoice`, `.pot` in `/languages`).
Translate it with Loco Translate, Poedit or on [translate.wordpress.org](https://translate.wordpress.org/projects/wp-plugins/easy-invoice/).

## Installation
1. In your WordPress admin go to **Plugins Add New**, search for “Easy Invoice”,
click **Install Now**, then **Activate**. (Or upload the zip under **Plugins Add
New Upload Plugin**.)
2. Open **Easy Invoice Settings** and enter your business name, address, logo, currency
and default terms.
3. Under **Settings Payments**, connect PayPal and/or enable bank transfer, cheque
and cash.
4. Go to **Easy Invoice Clients** and add a client, then **Easy Invoice Invoices
Add New** to create your first invoice. Send it from the invoice screen; the client
receives an email with the PDF and a private link.
**Requirements:** WordPress 6.0 or newer, PHP 7.4 or newer. Any properly coded theme
or page builder.
**Easy Invoice Pro:** install the Pro plugin from your purchase email next to the
free one, then switch on the addons you want under **Easy Invoice Addons**. Pro
needs Easy Invoice 2.4.0 or newer.
## FAQ
### Is the free plugin limited in any way?
No. Unlimited invoices, quotes, clients and PDFs, with no watermark and no time
limit. Pro adds optional addons; it does not unlock things the free plugin holds
back.
### Which payment methods can clients use?
Free: PayPal, plus bank transfer, cheque and cash recorded against the invoice (
clients can upload proof for you to approve). Pro adds Stripe, Square, Authorize.
Net, Mollie, Paystack and Moneris. You can also put any provider’s payment link
on the invoice.
### Are there transaction fees?
None from Easy Invoice. Your payment gateway charges its own fees.
### Can clients pay in instalments, or pay a deposit first?
Yes, with the Partial Payments & Deposits addon (Pro, Personal tier).
### Can I set up recurring invoices?
Yes, with the Recurring Invoices & Subscriptions addon (Pro, Personal tier): invoices
are generated and emailed on the schedule you set, with optional automatic charging
through Stripe or PayPal.
### Can I customise the invoice design?
The free plugin ships nine designs and lets you add your logo, business details,
colours and renamed labels. The Pro PDF Toolkit adds watermarks, headers and footers;
the Custom Templates addon adds a visual layout builder.
### Can I issue a credit note or a statement?
Yes, both are in the free plugin: credit notes are issued against a paid or partly
paid invoice from the invoice screen, and a client statement (with running balance)
is available from the client record.
### Are invoice links safe to email?
Yes. Since 2.4.0 every invoice and quote link carries a per-document access key.
A document is shown only to you, to the signed-in client it belongs to, or to someone
opening the emailed link — never to anyone who guesses a URL. Links sent before
2.4.0 show a page that offers to email a fresh link to the address the document
was issued to.
### I see “Page not found” when opening an invoice.
Go to **Settings Permalinks** and click **Save Changes** once — this refreshes
WordPress’s URL rules. If you use a caching plugin, clear its cache.
### Can I import data from another invoicing plugin or a spreadsheet?
Yes. **Easy Invoice Import** migrates directly from Sliced Invoices and Sprout
Invoices (with a dry-run count first), and accepts CSV files of clients and invoices—
download the CSV templates from the same screen. Exporting to CSV, Excel or PDF
is part of the Pro Bulk Email & Export addon.
### Does it work with WooCommerce?
The free plugin runs alongside WooCommerce without conflict. The Pro WooCommerce
Invoicing addon creates an Easy Invoice invoice for every paid order and turns refunds
into credit notes.
### Does it work on multisite?
Yes. Each site keeps its own invoices, clients and settings.
### Is there a REST API?
Yes — invoices, quotes, clients and PDFs, authenticated with WordPress application
passwords. See the [API reference](https://easy-invoice.matrixaddons.com/docs/api-reference).
### How does the Pro addon system work?
Pro is one plugin containing 26 addons. Under **Easy Invoice Addons** you switch
each one on or off. The 16 Personal addons work as soon as Pro is installed; Professional
and Agency addons need a licence of that tier. An addon you leave off loads no code.
### What if I update Pro before the free plugin?
Pro 2.3.0 needs Easy Invoice 2.4.0. If Pro is updated first it stays inactive with
a notice until the free plugin is updated, and the secure links your clients already
hold keep working meanwhile.
### What happens to my data if I stop paying for Pro?
Nothing is deleted. Personal addons keep working; Professional and Agency addons
pause until the licence is renewed. Every document stays in your database and the
free plugin continues to work with it.
### How do I report a security issue?
Please do not open a public forum thread. Report it through the [Patchstack Vulnerability Disclosure Program](https://patchstack.com/database/vdp/8b8da081-d07d-4239-b795-0f0895d186dd),
which validates reports and coordinates the fix with us, or use the [contact form](https://matrixaddons.com/contact/).
### Where do I get help?
The [documentation](https://easy-invoice.matrixaddons.com/docs/) covers setup and
every addon. Free users: the [WordPress.org support forum](https://wordpress.org/support/plugin/easy-invoice/).
Pro customers: priority support from the [account area](https://store.mantrabrain.com/).

We have an issue with adding clients and reached out to support. They responded

[sisco2016](https://profiles.wordpress.org/sisco2016/) 23 Lúnasa, 2025
The only plugin I like to use for invoicing my clients its Easy Invoice. It offers
a user-friendly interface and download as a PDF is the reason why I like it the
most. Communication always smooth and frequent through Mr Umsesh, with daily progress
updates.

## Changelog
#### 2.4.1 – September 15, 2026
* Fix: on phones the public invoice and quote pages clipped the line-item table’s
Total column and, in the Modern, Creative and Professional designs, the totals
box; every design now fits a 360px screen (narrower screens scroll the table
sideways).
* Performance: the payment script (and the jQuery it needs) loaded on every front-
end page of the site; it now loads on the public invoice page only. Filter `easy_invoice_load_payment_assets`
to add pages.
* Housekeeping: the changelog in this file now summarises each release; the complete,
itemised history lives in changelog.txt inside the plugin folder and on GitHub.
#### 2.4.0 – September 11, 2026
A large release; read the upgrade notice before updating. The full, itemised list(
about 190 entries) is in changelog.txt.
**Security**
* Invoices and quotes were readable, and enumerable, by anyone with
the URL, including drafts. Every document now needs a per-document access key (`?
ik=` / `?qk=`) carried by emailed links, a signed-in client, or an admin. Links
emailed before keys existed show a page offering to email a fresh keyed link to
the address the document was issued to; nothing is shown and drafts are never offered.*
Payment endpoints, PDF-download nonces, the payment callback, proof-of-payment file
names and the migration “skip” link all authorise properly; Pro card gateways no
longer bypass the authorisation check. Stored XSS through a client’s profile into
the builders fixed. Every output is escaped at the point it is printed; all redirects
go through `wp_safe_redirect`.
**New**
* Server-side PDF rendering (dompdf, now bundled): real, text-based PDFs
in every design, A4 / Letter / Legal, optional PDF attachment on invoice emails,
page numbers on multi-page documents. * Credit notes against issued invoices, statements
of account per client, and issued invoices can no longer be deleted permanently (
trash still works). * REST API at `easy-invoice/v1` (invoices, quotes, clients,
PDF download), authenticated and capability-checked; responses never expose access
keys. * Cross-border tax: reverse charge and export handling, VAT identifiers for
both parties with VIES checking, EN 16931 tax categories. * Import from Sliced Invoices,
Sprout Invoices and CSV. Attachments from the media library on invoices and quotes.
Client-view tracking (first and latest view, count). Convert-to-invoice on each
quote row. Clients search box. Uninstall routine that keeps your data unless told
otherwise. * New hooks and filters for addons: `easy_invoice_quote_total`, `easy_invoice_presented_access_token`,`
easy_invoice_reports_after_summary`, `easy_invoice_email_headers`, `easy_invoice_client_view_after_details`,`
easy_invoice_credit_note_actions`, `easy_invoice_text_setting` and others.
**Documents and designs**
* Every invoice and quote design reset and tidied; the
public page is a real WordPress page laid out as an A4 sheet, themeable from `{theme}/
easy-invoice/`. “Total Due” in every header; Credit note / Paid / Balance due rows
once anything is paid; the “To” block names the contact, phone and VAT number; totals
rows read in calculation order; the Legacy design prints Terms & Conditions; Minimal
quote markup fixed. * Stock emails rewritten as plain business correspondence; receipts
and payment notices correct for partial payments; “Test Template” works; emails
sign off with the business name.
**Fixes (selection)**
* Correctness: duplicate invoice, quote and credit-note numbers
under concurrent use; negative totals from oversized discounts; line amounts that
did not add up to the subtotal; dates defaulting to UTC instead of the site’s timezone;
taxable state of new lines; “Apply Tax” that could not be switched off; quotes that
never expired; acceptance and decline details never saved; quote conversion producing
empty lines; customer details dropped on save; attachments that could not be removed.*
Payments: overdue and part-paid invoices could not be paid from their page; a part-
paid or credited invoice asked for the full amount again; PayPal IPN left invoices
unpaid; bank transfer, cheque and cash from emailed links were refused; “Add New
Payment” could not record a payment; trashing or restoring payments left the invoice
status untouched; failed or refunded payments put issued invoices back to Draft.*
Admin: team members could not open any screen; the admin was unusable on phones;
Dashboard Edit/View links, the invoice list status filter, Reports totals and date
ranges, the “Delete client only” option (it deleted the documents), settings image
fields, colours that never rendered, sideways-scrolling lists, keyboard and touch
access to row actions, about 140 untranslatable strings. * Performance: invoice
totals are stored (dashboard, lists, reports and statements no longer rebuild every
model); admin screens that took 30–40 s on a few thousand invoices open in under
a second; the Overdue filter, Add Payment picker and payments totals answered from
single queries (10,000-invoice stores: 19 s 3 s); rewrite rules no longer flushed
on every request; the admin loads 47 KB of CSS instead of 2.8 MB. * Packaging: all
CDN assets (jsPDF, html2canvas, Chart.js, Select2) bundled; Composer dependencies
resolved for PHP 7.4; dead classes, duplicate AJAX registrations and an endpoint
that fataled removed; addon descriptions corrected to what is actually implemented.
#### 2.3.8 – August 21, 2026
* Compatibility – **Tested and confirmed compatible with WordPress 7.1.** “Tested
up to” bumped from 7.0. The release was audited against the 7.1 codebase rather
than smoke-tested: every WordPress function the plugin calls was resolved against
the 7.1 symbol table (no removed or renamed API is used), the plugin’s global
function, class and constant names were diffed against the 92 functions and 5
classes 7.1 introduces (no redeclaration collisions), and the full plugin tree
was scanned with PHPCompatibility for PHP 7.4 through 8.4 (zero issues).
* Compatibility – **jQuery UI 1.14.2** ships in WordPress 7.1 (up from 1.13.3).
The payment-gateway drag-to-reorder list on Settings -> Payment uses `.sortable()`
and `.disableSelection()`; both remain available because core enables `jQuery.
uiBackCompat` and still bundles the disable-selection module. The four APIs 1.14
removed (`$.fn._form`, `$.ui.ie`, `$.ui.safeActiveElement`, `$.ui.safeBlur`)
are not used anywhere in the plugin.
* Compatibility – **The enforced iframed post editor in 7.1 does not affect Easy
Invoice.** Invoices and quotes are edited through the plugin’s own admin screens;
their post types register with `show_ui => false` and the one UI-visible post
type does not declare `editor` support, so no plugin JavaScript or CSS reaches
across the editor document boundary.
* Compatibility – Admin styling verified against 7.1 markup: the `#adminmenu`, `#
adminmenuwrap`, `#adminmenuback`, `#wpcontent`, `#wpbody-content` and `#wpfooter`
containers the plugin restyles are all still emitted by `wp-admin/admin-header.
php` and `menu-header.php` in 7.1, and the persistent admin toolbar change touches`#
wpadminbar`, which the plugin does not style.
* Compatibility – The REST and media changes in 7.1 (image dimension validation
on the sideload endpoint, size-aware encoding quality in attachment responses)
are not applicable: the plugin’s REST routes are its own (no media, sideload
or attachment endpoints) and it calls no attachment or sideload APIs.
* Fixed – **Payment-gateway drag-to-reorder relied on incidental script ordering.**
The `easy-invoice-settings` script handle is registered in two different places,
and WordPress keeps whichever registration runs first while silently discarding
the other’s dependency array. The registration that wins did not list `jquery-
ui-sortable`, so `settings.js` was printed ahead of jQuery UI Sortable and only
worked because its code runs inside a DOM-ready callback. The jQuery UI handles
are now declared explicitly on that registration, so `wp_scripts` resolves the
load order instead of it falling out of enqueue sequence – worth tightening now
that 7.1 ships a new jQuery UI build.
#### 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 directly at `?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 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 (`` + `window.location.replace`) when the server-side redirect can’t fire
because upstream output already flushed the response headers. Email download
links, dashboard widgets, and any other integration calling these endpoints
directly benefit from the same hardening.
#### 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 – The `[easy_invoice_url]` and `[easy_quote_url]` shortcodes no longer
generate per-document access keys for arbitrary visitors. Keys are now produced
only when an invoice or 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 – The bound-client authorisation path on quote Accept / Decline and invoice
manual-payment submission silently never succeeded for logged-in customers. The
guard relied on PHP’s `method_exists()` which returns false for `__call`-resolved
methods, and both the Invoice and Quote models resolve `getClientId()` that way.
Logged-in clients whose email matches the document’s bound client are now correctly
recognised. (Admin and emailed-link paths were unaffected.)
* Note – Emailed `{{invoice_url}}` and `{{quote_url}}` 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 (they can still view the document—
only the Accept / Decline / submit-manual-payment paths require the key).
#### 2.3.5 – June 26, 2026
* Security – Hardened authorisation on the manual-payment submission flow. **All
sites should update.**
* Improved – Invoice share links emailed to clients (`{{invoice_url}}` in email
templates, `[easy_invoice_url]` shortcode) now carry a per-invoice access key.
Recipients of these links can submit “I paid by bank transfer / cheque” entries
as before — no extra steps for the customer.
* Note – Invoice links generated **before** this update will still load and display
the invoice and accept online gateway payments (Stripe / PayPal / etc.). The
manual-payment submission form appears only after the admin resends the invoice(
which produces a new link) or after the client logs in to the WordPress account
whose email matches the invoice’s bound client. Admins are unaffected — the form
is always available from the admin UI.
* Fixed – Race condition under high concurrency where two simultaneous invoice (
or quote) creates could be assigned the same number. The counter read-check-write
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 plans are correctly placed in their tier and see the
matching variant label on the License page.
