Minvoice

Minvoice runs in your own Cloudflare account and keeps the books in a D1 database. Clients see invoices, emails, the pay page and PDFs in English, Spanish, German or French. The admin sits behind a password or Cloudflare Access.

Invoices take multiple line items, per-client payment terms and default rates, and custom or automatic numbering with optional date-based prefixes. A print view stamps them PAID or VOID, and invoice emails carry a generated PDF. Each invoice keeps a timeline of edits, sends, payments and pay-link views, and you can undo a recorded payment. Clients pay from a link carrying a 100-bit token, by card through Stripe Checkout or through PayPal. You record checks and bank transfers by hand. Stripe and PayPal webhooks are the source of truth: the Worker deduplicates them and commits each payment, status change and queued receipt email in one transaction. Opt-in reminders email overdue clients on an editable schedule, by default 1, 7 and 14 days after the due date. Monthly reports can be filtered by client, and invoices and payments export to CSV. The Worker is built on Hono with server-rendered JSX and uses D1, static assets for self-hosted fonts and styles, and a Cron Trigger that sends reminders at 15:00 UTC. Email goes out through Resend or a Cloudflare send_email binding. The admin accepts the ADMIN_PASSWORD secret until you configure Cloudflare Access; from then on the Worker verifies Access JWTs and fails closed. The Worker envelope-encrypts API keys you enter in the app with AES-256-GCM before storing them in D1. The Deploy to Cloudflare button clones the repository to your GitHub account, provisions and migrates D1, and asks only for ADMIN_PASSWORD. A setup wizard runs on your first visit to /admin. Stripe, PayPal and Resend keys can be entered in Settings or set as Wrangler secrets, which take precedence. For a CLI setup, npm create minvoice scaffolds a fresh copy and prints the same steps.

Built for: Freelancers, consultants and single-business owners who want self-hosted invoicing without a monthly subscription

What you can use it for

• Send invoices to clients with the PDF attached
• Collect card and PayPal payments through a pay link
• Remind clients automatically when an invoice is overdue
• Check monthly totals and export payments to CSV for bookkeeping

Deploy

• One-click · main path

  Branch main

  Deploy to Cloudflare

• CLI

  Branch main

  Paste the database_id that d1 create prints into wrangler.jsonc before running the remaining commands.

  npm install
  npx wrangler d1 create minvoice
  npx wrangler types
  npm run db:migrate:remote
  npx wrangler secret put ADMIN_PASSWORD
  npm run deploy

  Copy

Payments and email are optional and can be added after the button deploy. Stripe and PayPal each need their keys and a webhook registered in their own dashboard, and email needs a provider and a From address in Settings.

What it needs to run

• Email sendingEMAIL

Good to know

Putting the admin behind Cloudflare Access needs a custom domain. Invoice PDFs do not support right-to-left or Indic scripts, and CJK text needs your own font files in a fork. The admin UI is English only. The project started in July 2026 and has one maintainer. There are no tagged releases.
