The Solution
Unstoppable Invoices and Estimates for SureCart solves this automatically โ install once, and it works in the background.
Built specifically for real businesses running WooCommerce stores, just like yours.
What You Get
Everything included, no hidden add-ons
Invoicing that lives where your store already does
SureCart handles products and subscriptions beautifully. It was never built for the other half of the business.
The gap
The custom job you quoted last week. The consulting hours you bill monthly. The B2B client who wants net-30 terms and a PO number. The accountant who needs a PDF for the file.
So you bolt on a second tool. Customer records now live in two places, payments get reconciled by hand at month end, and nobody is certain whether invoice #1042 ever got paid.
The fix
Unstoppable Invoices and Estimates puts real invoicing inside SureCart, built on the customers, products, and checkout you already have.
Draft an invoice in under a minute, send it, and watch the payment post itself against the right record. Nothing to export, nothing to key in twice.
Quote first, bill later. Send an estimate for approval, then convert it into an invoice without re-entering a single line item.
Manual invoices
Build an invoice from scratch with custom line items, quantities, and descriptions. No product record required.
Estimates and quotes
Send a quote before the work starts. One click converts an approved estimate into an invoice.
Your existing customers
Search and pull in SureCart customers as you type. New clients are created in SureCart, not in a side database.
Pay through SureCart checkout
Clients pay through the same secure checkout and payment processors your store already uses.
Payments sync automatically
Paid invoices update themselves. Status, date, and amount stay accurate without a manual reconciliation pass.
Professional PDFs
Every invoice and estimate downloads as a clean, branded PDF for your records, your client, and your accountant.
Email delivery
Send an invoice or estimate straight from the dashboard, with a secure payment link included.
Tax configuration
Set your tax handling once and apply it consistently across every document you send.
Status at a glance
Draft, sent, paid, overdue. See where every invoice and estimate stands from a single list.
Inside your WordPress admin
Runs under SureCart Studio alongside your other Unstoppable plugins. No new login, no third-party portal.
When a client asks whether they've been billed, the answer is one screen away.
