Editorial
A payment provider moves money. It doesn't decide what to charge. Enterprise payment solutions handle subscription and usage-based billing by charging a stored credential on a schedule you set, while metering, rating, credits and invoicing sit in a separate billing engine. Flexprice isn't a payment processor either.
Key Takeaways
Stripe's docs name Metronome its "primary usage-based billing platform, recommended for all new integrations", and say Billing Meters "only reconciles usage at invoice time".
Adyen acquired Orb for $335 million, closing on July 1, 2026. Stripe completed its Metronome acquisition on January 14, 2026.
Stripe Tax calculates sales tax, VAT and GST. TaxJar, Taxually and Marosa do the filing.
Flexprice isn't a payment processor. It rates 20B+ events a month at up to 1 million events per second, then hands the charge to Stripe, Razorpay, Moyasar or Nomod.
How do payment platforms support subscriptions?
They charge a stored credential on a schedule you define. Each vendor words it differently:
Braintree: a plan sets a billing cycle, an amount and a trial.
Adyen: "recurring transactions you initiate at regular intervals", against a stored token.
Stripe: subscriptions plus the Invoicing API, with terms set by
days_until_due.
"Subscription" does three different jobs there. Pin that down in the first call.
What usage-based billing capabilities do payment providers have?
Fewer than the name suggests, and Stripe writes the gap down itself. Its comparison page marks these unsupported on Billing Meters:
Prepaid credits and drawdown.
Enterprise contracts, commits and minimums.
Ramp schedules.
Dimensional pricing.
Real-time usage visibility.
The credits footnote is worth reading twice: "Credits are only reconciled at invoice time. Customers can exceed their balance during the cycle."

Where do payment processing and billing engine responsibilities split?
Stripe publishes the split itself: Metronome "handles metering, rating and billing, while Stripe handles payment collection, tax calculation and revenue recognition". Every cell below is sourced, or reads "Not listed".
Responsibility | Payment provider | Billing engine |
|---|---|---|
Authorize, capture, settle, disputes | Yes | No |
Usage metering | Stripe at invoice time; others not listed | Yes |
Rating against a contract | Not listed | Yes |
Credit drawdown, ramped commits | Not on Billing Meters | Yes |
Invoice assembly, net terms | Stripe: 250 line items max | Yes |
Nobody scopes what nobody documented, so the "Not listed" rows cost most. That's the gap between collecting a payment and running billing.
How do you handle invoices, purchase orders, and net terms?
Net terms are a field and a PO number is free text. Stripe's Invoicing docs give you three things:
days_until_due=30sets the term and marks the invoice overdue.Custom fields hold "up to four key-value pairs", one common use being PO numbers.
That isn't a purchase order drawn down across quarters, which is what procurement sends.
How do enterprise payment solutions handle multi-currency and tax?
Multi-currency means presentment and settlement. Tax means calculation:
You can charge "in over 135 currencies" and settle into your preferred one.
Stripe Tax calculates sales tax, VAT and GST and monitors registration thresholds.
Filing runs through partners, including Marosa across "27 EU and Europe countries".
The seam is the contract. The payment layer never sees which currency you negotiated in, or which one a credit balance sits in.
When do enterprises need a separate billing platform?
When the contract stops being a price and starts being a document. These triggers do it:
Prepaid credits that draw down inside the cycle.
Ramped commits with mid-cycle overages.
Parent-child accounts, where a group signs and subsidiaries consume.
Contract versioning, audit trails and data residency for security review.
More than one payment gateway across regions.
Hit three and you're shopping for enterprise billing software. Two payment companies bought two billing engines in the first half of 2026, which argues it better than I can.
What does Flexprice do that a payment provider doesn't?
Flexprice is enterprise-grade, open source usage based billing infrastructure for AI and SaaS companies. It can be deployed in your own VPC, on-prem, or on Flexprice's managed cloud. It isn't a payment processor and isn't tied to any payment gateway. Against those triggers:
Usage Metering rates up to 1 million events per second at under 60ms P99.
Credits and Wallets gives in-cycle drawdown, rollover and auto top-ups, from Scale.
Pricing Models runs ramped contracts and commitments whose overages bill separately.
Billing and Invoicing puts credits, usage and subscriptions on one document.
Parent-child accounts, contract versioning, RBAC and audit trails ship in the AGPL-3.0 build. SOC 2 Type 2, SAML SSO and on-prem or air-gapped deployment sit on Mission Critical.
One instance bills through Stripe, Razorpay, Moyasar and Nomod.
We rate 20B+ events and 5B+ API requests a month for 100+ customers, including Simplismart, Segwise and CASParser.
One honest limit: if you sell one flat plan on a card, Stripe Billing covers it and Flexprice is overhead. Otherwise take those rows to your provider's docs, then book a demo.
Frequently asked questions
Do payment processors handle usage-based billing?
Partly. Stripe's docs say its Billing Meters API "only reconciles usage at invoice time", and mark prepaid credits, commits and ramps unsupported.
What's the difference between a payment gateway and a billing engine?
A gateway authorizes, captures and settles money. A billing engine meters usage, rates it against a contract and produces the invoice.
Can Stripe handle purchase orders and net 30 terms?
Yes, at a basic level. Net 30 is the days_until_due parameter, and a PO number goes in one of four free-text custom fields.
Does a payment provider handle tax filing?
Stripe Tax calculates sales tax, VAT and GST and offers automated US filing. Filing elsewhere runs through partners like Taxually and Marosa.
