The SaaS decisions that are expensive to undo
Every row of business data needs a tenant. Every request must prove which tenant it is. Shared database plus tenantId is enough for most early products. Separate databases per customer are for later—compliance, noisy neighbors, or enterprise contracts.
Billing events should live in your database even if Stripe (or similar) is the processor. Your SaaS should know who is paid if a webhook is late.
Ship the control plane before you need it
The week a customer asks you to reset a user, you will want a thin admin: find a company, change a plan, record a support login. I build that with the customer app so you are not doing ad-hoc database surgery.
React.js dashboards stay maintainable when pages stay thin and business rules do not hide in random components. That is SaaS as a product, not a pile of screens.
Questions business owners ask
Can you take a prototype and make it a real SaaS?
Yes. Typical work is adding tenancy, auth, roles, billing, and a deploy path to something that was demo-only.
Do I need Kubernetes to be a serious SaaS?
No. You need deploys with rollback, searchable logs, and alerts on login and checkout. I match DevOps to a small team, not a fashion stack.
What do you need from me to estimate?
Who the tenants are, what each tenant’s users do, how you want to charge, and which integrations are must-haves for v1.
