Finance and accounting decision
Southern East Inc.
A competent developer can build a useful self-hosted replacement in a few weeks using existing OSS components (invobook, InvoiceNet) and standard APIs; you give up vendor polish, native apps, and commercial support.

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 Southern East Inc. alternatives, with the arithmetic →
What a replacement has to do
- Create an invoice from a customer record, render as PDF, send invoice email and record payment status; optionally accept natural-language invoice creation via a hosted LLM API.
What it still won’t have
- Polish of mobile-first native apps and polished UX refinements
- Priority/white-glove support and SLA-backed uptime
- Built-in accounting integrations and advanced automations
- Any proprietary AI tuning or data the vendor may have
- Marketing, brand trust, and pre-existing customer base
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted invoicing web app with Node.js (Express), Postgres, and React; deploy to a single small cloud VM (e.g., DigitalOcean). In scope: user sign-up and simple auth (email/password), customer and product CRUD, invoice/estimate create-edit-send flows, server-side PDF generation (e.g., Puppeteer or PDFKit), Stripe payments integration, scheduled job for reminders, and an optional integration to OpenAI for natural-language invoice drafts. Out of scope: multi-tenant SaaS billing, native mobile apps, advanced accounting double-entry features, and large-scale analytics. Include error handling, input validation, basic unit/integration tests, Dockerfile, and deployment scripts.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 4 cited sources+3
- Evidence score60
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.
