Why Use Meku for an Invoice Generator
Meku builds invoicing around your billing rules, not a fixed invoice template.
- React and Tailwind code you can read and edit
- Stripe integration so clients pay from the invoice
- Supabase integration for clients, invoices, and payment records
- Export to GitHub or ZIP with full code ownership
Free online invoice generators do not store your history or connect to payment. Invoice software charges monthly per user.
Who This Is For
For freelancers, small businesses, and developers who need billing shaped around their work.
- Freelancers billing hourly or by project
- Small businesses avoiding per-seat software
- Trades billing parts and labor
- Developers building billing tools for clients
If standard invoicing software does not match how you charge, this builder fits your workflow.
