How it works

How working capital runs on Fynex

Three steps from setup to settled — then it runs itself.

  1. 1

    Reads every supplier term

    Fynex reads the terms on every bill as it arrives — early-payment discounts, net days, late-fee clauses — across software vendors, contractors and trade suppliers. Nothing hides in a PDF anymore.

  2. 2

    Ranks against your cash floor

    It checks the discount on offer against your cash floor and what else is due, then ranks each bill: pay early to capture the discount, or safely delay to hold the cash. You set the floor once.

  3. 3

    Pays at the right moment

    Fynex pays each bill on the day that captures the discount or lands just inside the due date — never early enough to strain cash, never late enough to draw a fee. Every payment books itself back.

From the discount on every invoice to the day each bill goes out — weighed against your cash floor, run for you.

FAQ

Questions, answered

It reads the terms on every bill as it arrives — software vendors like Adobe and Figma, contractors, trade suppliers — and detects clauses such as 2/10 net 30. You don't have to open a single PDF or remember which supplier offers what.
The cash floor is the minimum balance you want to keep in the account. You set it once. Fynex weighs every pay-early recommendation against it, so capturing a discount never drains cash you needed for payroll or other bills due that week.
A 2% discount for paying ten days early sounds small, but over a year it works out to roughly a 36% return on the cash you put in early. Fynex shows that figure per bill so you can compare it against simply holding the cash.
Fynex holds them to the last safe day inside their terms, so the cash stays in your account as long as possible without ever drawing a late fee. You keep the working capital without the risk.
Agencies feel it first because software-vendor and contractor terms add up fast, but it works for any operator with suppliers — trade accounts, marketplaces, professional services. Anywhere bills carry terms, there's working capital to recover.
Yes. Once you approve the run, Fynex pays each bill on the day that captures the discount or lands just inside the due date, on the cheapest compliant rail, and books every payment back to your accounting automatically.
