Tenancy and billing decided before the first screen
The two decisions that quietly define a SaaS product are how you isolate tenants and how you charge them. We settle both early. Shared schema with row-level security, schema-per-tenant, or database-per-tenant each has a cost, and we pick the one that matches your compliance story and your scale, not the one that is fashionable. Billing is wired to the same model, so plan limits, seat counts, and usage metering read from one source of truth rather than three that drift.
