Build a B2B SaaS Tool in 21 Days
Internal dashboards, workflow automation, and vertical SaaS — shipped at a fixed price.
Why B2B Tool development is hard to get right
B2B tools need multi-tenant isolation from day one — retrofitting RLS costs double the build
Enterprise buyers expect SSO, audit logs, and role-based permissions even in v1 demos
Vertical SaaS niches are underserved by horizontal tools — custom beats Notion/Airtable for specific workflows
Per-seat pricing logic with Stripe Billing is consistently underscoped by freelancers

Frequently asked questions
Do you build vertical SaaS or horizontal tools?
Both — but vertical SaaS (one industry, deep workflow) converts better at MVP stage. We scope around your ICP's single most painful workflow.
Can you add SAML SSO for enterprise?
Yes via WorkOS — typically 2–4 days of integration. We recommend launching without SSO, then adding it when enterprise deals require it.
