The problem
Invoicing is busywork that leaks money
Someone raises each invoice by hand, hopes the numbers are right, attaches a PDF and waits to be paid — then reconciles it all later. Errors slip through, duplicates get paid, and cash comes in slow.
Fynex runs the whole thing. It raises and sends invoices automatically, reads each one with AI to catch the mistakes, and gets you paid on a link that reconciles itself back to your books.

How it works
How invoicing & collections runs on Fynex
Three steps from setup to settled — then it runs itself.
1
Fynex raises the invoice
From your billing rules and accounting, Fynex creates and sends each invoice automatically — branded, in the right currency, on schedule. You stop typing invoices one by one.
2
AI checks every one
Before an invoice goes out or gets paid, Fynex reads it — flagging duplicates, wrong amounts, missing terms and rate drift — so the error is caught before it costs you, not after.
3
Paid on a link, reconciled
Your customer pays on a branded link with cards, Apple Pay or Google Pay. The moment it's paid, Fynex books it back to your accounting — tax and currency handled.
What Fynex runs

Raised and sent for you
Auto-invoicing

The intelligence layer
The intelligence behind every invoice
Fynex reads every invoice as it's raised and as it's paid, catching the duplicate, the wrong amount and the rate that drifted before it costs you, and booking each payment back the moment it lands. The busywork that quietly leaked money, gone.
Reads every invoice for duplicates, wrong amounts and missing terms before it sends
Flags supplier rate drift the moment an amount breaks the contract
Picks the right tax treatment per customer country, including EU/UK VAT reverse-charge
Chases each unpaid invoice on its own schedule until it's collected
Matches every payment back to the invoice that raised it

Fynex reads every invoice and flags problems before they cost you: duplicates, wrong amounts, missing terms or PO numbers, and supplier rate drift. You catch the error before it's paid, not after — without anyone checking line by line.
A secure, branded payment link you (or Fynex) send to a customer. They pay on a hosted checkout — cards with 3-D Secure, Apple Pay or Google Pay — and the payment reconciles itself back to your books. Links can be one-off or reusable.
Yes. Turn a link or invoice into a subscription with a free trial, promo codes and a monthly or annual schedule. Failed charges are retried automatically, and every charge is recorded against the customer.
Yes. Collect in USD, GBP, EUR and more, and Fynex applies the right tax treatment for the customer's country, including EU/UK VAT reverse-charge, with the evidence kept on file — so cross-border billing stays compliant without manual work.
Every payment is matched to the invoice or link that generated it and booked to your accounting, so what came in always ties out — no manual matching after the fact.
