Why we built Fynex

Moving money by hand
has a price

At 25 invoices a week, doing it by hand costs you about £15,600 a year.

Fynex runs it for you, so that number goes to zero.

A thinking layer on top of your money stack

Cards, AP, treasury and your system of record are horizontal layers — each one executes a slice of the money chain and stops. Stack them and you still have no one reasoning across the whole thing.

Fynex is the layer above all of it. It reads every layer at once — what's owed, what's due, what's in flight, what each supplier's terms say — and reasons about what to do next. That's the difference between a stack that runs and a stack that thinks. And because the layer runs on AI agents, the thinking doesn't stop at a recommendation: it becomes the payment, the payout, the booked entry.

What Fynex watches

Ten things it's thinking about, right now

Across every account, supplier and payment you run — Fynex watches for the move worth making, continuously.

Value to capture

Money you'd otherwise leave on the table.

Discount opportunities

Early-payment terms worth capturing before they lapse.

FX optimisation

The cheaper corridor or rail for money crossing borders.

Recurring patterns

Spend and inflows that repeat, surfaced before you ask.

Risk to catch

Leaks and mistakes, stopped before they cost you.

Late-fee risk

Bills drifting toward a fee, held to the last safe day.

Duplicate-payment risk

The same invoice about to be paid twice.

Vendor data drift

A supplier quietly changing terms, rates or bank details.

Approval bottlenecks

Payments stuck waiting on a sign-off that's overdue.

Cash to protect

Your position and liquidity, watched in real time.

Cash-floor warnings

The date your position is projected to breach the floor.

PSP refund coverage

Whether your processor balance covers pending refunds.

Currency imbalance

Balances drifting out of line with what you owe per currency.

How a recommendation works

Every recommendation, on your terms

Fynex proposes. You decide. Nothing moves money without you.

  1. 1

    See the reasoning

    Each recommendation opens to the numbers behind it — the terms it read, the rule it applied, the saving it found. No black box, no 'trust us'.

  2. 2

    Check the confidence

    Every recommendation carries a confidence score, so you know which to wave through and which deserve a second look before you act.

  3. 3

    Act, snooze or dismiss

    Approve in one click, snooze it for later, or dismiss it and Fynex learns the boundary. Every choice is written to the audit log.

Fynex in action

Three moments, real numbers

Not abstractions — the kind of call Fynex makes for you on an ordinary Tuesday.

Discount capture

It caught a discount you'd have missed

An Adobe invoice arrived with a 2/10 net 30 term. Fynex checked it against your cash floor, saw room, and recommended paying early.

Rate drift

It flagged a rate that quietly drifted

A contractor's new invoice came in 18% above their rate card. Fynex caught the drift before the payout run and held it for your review.

It found a cheaper rail for a cross-border payout

A $42,000 payout was about to go SWIFT. Fynex found a local rail and a better corridor, and re-routed it before it left.

The trust model

It shows its work, every time

An intelligence layer is only useful if you can trust it. So Fynex is built to be checked: every recommendation shows its maths, every action needs your approval, and every transition is logged.

FAQ

Questions, answered

It's the part of Fynex that thinks. The rest of the platform executes the money chain — payments in, payouts out, reconciliation back to your books. The intelligence layer sits on top of all of it and reasons: it watches for discounts to capture, fees to avoid, rails to optimise and risks to flag, then recommends the next action with the maths attached.
Most finance tools execute and stop — they pay the bill, move the card spend, push the payout. They tell you what you spent. Fynex reasons across the whole money chain and tells you what to do next and what it's worth, so value gets captured instead of left on the table.
No. Every recommendation shows its reasoning and its confidence, and every action that moves money requires your approval. You can act in one click, snooze it, or dismiss it. Nothing happens behind your back, and every transition is written to the audit log.
It reads your own signal — your suppliers' terms, your cash floor, your rails, your accounting — not a generic benchmark. The same engine runs across every vertical; what changes is the data it reads and the benchmarks it compares against, so an agency and a marketplace each get recommendations grounded in their own numbers.
Always. Every recommendation opens to the reasoning behind it — the numbers it used, the rule it applied and the confidence it has — so you're never asked to trust a black box. If you disagree, you dismiss it and it learns the boundary.
