Finance and accounting decision
Zenvoice
A competent technical user can build and maintain a one-account replacement in ~32 hours; no durable moats are evident and open-source invoicing projects exist as prior art, so keep paying only if you value the hosted polish and support.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Zenvoice alternatives, with the arithmetic →
What a replacement has to do
- Connect a Stripe account, list successful payments, let a customer confirm email and edit invoice fields, render a compliant PDF invoice, and provide bulk export (ZIP/CSV).
What it still won’t have
- Hosted, polished UI and cross-account dashboard
- Paid product support and marketing ecosystem
- Lifetime purchase distribution channel and existing user trust
- Built-in promotional/affiliates flow and checkout pages
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted Stripe-invoice generator using Node.js (Express) + React, Postgres, and S3 for file storage. Core features in scope: Stripe account connection with restricted API keys, listing successful payments, secure customer email confirmation flow, editable invoice form (VAT, Tax ID, company details), server-side PDF generation from a compliant invoice template, per-invoice download, CSV export, and ZIP bulk-download. Out of scope: multi-tenant billing UI, affiliate program, marketing pages. Include authentication for the admin dashboard, input validation, error handling, unit tests for API routes, and simple deployment scripts (Docker + provider guidance).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
