The tool that works for you won't automatically work for a second customer
Plenty of good internal tools get built assuming exactly one company will ever use them — the customer ID nobody added, the config hardcoded because there was only one answer, the query that trusts every row belongs to you.
Turning that into a product customers can sign up for means adding an account model, billing, and tenant isolation that holds even when you're not the one testing it. It's a different engineering problem, not just more customers.
Signs it's time
A prospect asked to buy the internal tool · tenancy is assumed, not enforced · billing would be handled by hand · you don't yet have a self-serve signup
What we build
Tenant isolation
Every query scoped and tested so one customer's data can never leak into another's view.
Account & billing
Signup, subscriptions, invoicing and plan limits wired to a real payment provider.
Team & permissions
Each customer manages their own users and roles without your involvement.
Configurable limits
Plan tiers enforced in code, not by someone remembering who paid for what.
Self-serve onboarding
A new customer can sign up and start using it without an engineer in the loop.
Usage & observability
Per-tenant metrics so you know who's active, who's at risk, and where load is going.
How long it takes
2–3 weeks
Tenancy audit
We find every place the current system assumes a single customer.
10–16 weeks
Multi-tenant foundation
Isolation, accounts and billing built and tested with a second real customer.
Ongoing
Scale
Plan tiers and limits refined as real usage patterns show up.
