Who checks it

Billing, product, support, or account automation.

Practical guide

Collect AI, SaaS, and API tool payments before usage credits, seats, or model access are added.

AI and API products often bill through credits, seats, usage limits, or prepaid balances. Payment needs to connect directly to entitlement.

Crypto can fit developer customers, global startups, Web3 teams, and users who prefer stablecoin payments for software.

Why usage products need payment-to-entitlement mapping

A user paying for credits expects those credits to appear. A workspace paying for seats expects access to change.

The payment record should contain workspace, plan, credit, and invoice metadata so automation can do the right thing.

Credits need precision

Paid status should add the correct usage amount.

Developers expect speed

A clean checkout reduces support interruptions.

Global SaaS fits

Stablecoins can help customers outside card markets.

How MakePay fits SaaS billing

Use API-created payments for product-native checkout or payment links for manual invoices and enterprise balances.

Webhooks can update credits, seats, subscriptions, or access after payment.

Credit top-ups

Add prepaid usage after paid status.

Enterprise invoices

Collect larger workspace payments by link.

Direct settlement

Keep settlement wallet-first while product logic remains internal.

Scenario

Setup path

Start with one clear payment moment.

Launch the first flow, prove the status handoff, then expand into nearby payment moments once the team trusts the signal.

1

Define entitlement

Credits, seats, plan, model access, or usage balance.

2

Create payment

Attach workspace, user, and invoice metadata.

3

Update product after payment

Use webhooks or dashboard status.

4

Reconcile usage

Keep payment and entitlement history together.

Questions

Can this add API credits?

Yes. Webhooks can connect paid status to credit allocation.

Can enterprise invoices use links?

Yes. Links are useful before a full billing integration.
