InvoiceFlow
Invoicing for small businesses, with a paper trail.
InvoiceFlow is multi-tenant invoicing software for small businesses. It creates invoices, keeps client history and notes, requests signatures, and stores a signed, tamper-evident receipt against every invoice it issues.
It was built for businesses that need an invoice to hold up later: who agreed to what, when, and with what attached. Every record carries its own audit history, and everything in it can be exported in full whenever you want it back.
