Why we use it
Why it earns a place in the stack
- Mature APIs for SaaS billing and marketplace payouts
- Strong webhook and Connect patterns for real workflows
- Clear path from prototype checkout to production reconciliation
- Widely understood by finance and engineering stakeholders
When we would not
When we recommend something else

FAQ
Questions teams ask
Straight answers on stack choices, fit, and how we engage.
Yes. Marketplaces and platforms often need connected accounts, splits and careful onboarding — we design that as a workflow, not a plugin.
Dunning, retries, customer communication hooks, dispute evidence paths and ledger reconciliation are part of the design.
Often. We plan customer migration, entitlement mapping and dual-running periods so revenue does not drop mid-cutover.
