The table we would want if we were evaluating us — including the row where we are the new option. Don't take it on faith; the sandbox is how you check every claim here.
| subinc | Build it yourself | Stripe Billing | |
|---|---|---|---|
| Gateway lock-in | None. The edge is adapters — swap a processor in a day. | Whatever SDK you coupled to. | Stripe-native. Leaving is a re-platform. |
| Double-entry ledger | Built in. Debits equal credits on every write, reconciled 1:1. | You build it and prove it holds. | Billing records, not a general ledger. |
| Multi-processor routing | Per tenant, per currency, or per rule. | Your own routing layer. | Single processor. |
| Data model ownership | Your Postgres, your rows, tenant isolation at the database. | Yours to design and maintain. | Stripe's objects, reached over the API. |
| Time to first charge | Minutes, in a free sandbox. | Weeks to months of plumbing. | Minutes. |
| Track record | New. No production tenure yet — so you verify it in the sandbox, not on our word. | Your team's, whatever it is. | Years in production at scale. |
You pay a platform fee plus metered usage on the events you send. Test-mode usage never bills. Exact rates are being finalized; figures on this page are illustrative.
