Why billing is the hardest infrastructure problem in fintech

For fintech companies, every transaction carries its separate cost and has to reconcile to the cent in real-time. You’re dealing with someone else’s money, so one wrong event can lead to margin loss, failed audit, and trust that you don’t get back.

Blurry margins

Interchange and processor fees change on every transaction. You can’t see true margin until it’s too late.

Real-time charges

Every transaction has to be billed the moment it happens, not at month-end.

Credits & wallets

Prepaid balances need real-time checks, expiry, and overdraw limits, without blocking a transaction.

Every segment differs

Self-serve, enterprise, and partners each want different pricing. You need all of it at once.

Built for every kind of fintech

Whether you process payments, embed finance, or run a neobank, your billing challenges are different. Flexprice meters, prices, and invoices all of them on one engine.

Payments & PSPs

Embedded finance

Neobanks & wallets

Scaling subscriptions

Go SDK example for sending customer usage events to Flexprice’s billing and metering API.

Know your exact margin on every transaction

Meter interchange, scheme, and processor fees as a single event, with real-time cost and margin visibility per transaction.
Price on take-rate, per-transaction, blended, or interchange++, and run them side by side.
Push per-customer rate cards live from a dashboard, not a sprint.
Reconcile billed revenue to processor settlement automatically.

Before Flexprice, billing required one developer to spend 20-30% of their daily bandwidth. After adopting Flexprice, no developer is dedicated to billing at all.

Payments & PSPs

Embedded finance

Neobanks & wallets

Scaling subscriptions

Know your exact margin on every call even when four vendors are on the bill

Track STT, LLM, TTS, and telephony as a single metered event with real-time cost visibility across every vendor.

Credits and wallets for prepaid developer plans with balance enforcement.
Per-customer pricing overrides that ship from a dashboard, not a sprint.
Run per-minute, per-call, and credit-based pricing simultaneously without separate billing logic

My team can update pricing per customer directly in the dashboard. What previously took 3-4 days of engineering work now takes 15-40 minutes end-to-end

From first event to first invoice in hours

Three steps. No billing expertise required.

STEP 1

Meter financial events

Send events (transactions, fees, payouts) through one API or SDK. Any event shape, real time or batch.

STEP 2

Configure your pricing model

Set up per-transaction, take-rate, tiered, or hybrid pricing in the dashboard. Switch models later with no code changes.

STEP 3

Invoice and reconcile

Flexprice generates line-item invoices, recognizes revenue and reconciles, with real-time dashboards for your customers.

STEP 1

Meter voice events

Send events (call start, call end, minutes used, tokens consumed) via our API or SDK. One endpoint, any event shape.

STEP 2

Configure your pricing model

Set up per-minute, credit-based, tiered, or hybrid pricing in the dashboard. No code changes needed to switch models later.

STEP 3

Invoice automatically

Flexprice generates line-item invoices showing exactly what your customer consumed. Real-time dashboards keep them in the loop.

One engine for every part of fintech billing

Metering, credits, and pricing that work the way money actually moves, not bolted onto a subscription tool.

Meter every fee and see every margin

Send transactions and their fee components (interchange, scheme, processor) as a single event.

Flexprice rates them the moment they land, so you see true margin per transaction instead of waiting for month-end reconciliation to find out.

Prepaid balances on a real-time ledger

Sell credits, minutes, or prepaid balances and let a built-in ledger do the hard part: real-time balance checks, expiry, and overdraw prevention under concurrency, without ever blocking a transaction.

Change pricing without shipping code

Model per-transaction, take-rate, tiered, or hybrid pricing and change it from a dashboard. Ship per-customer overrides in minutes, and grandfather existing contracts automatically when your pricing moves on.
