SaaS & B2B Software

The multi-tenant plumbing B2B buyers check before they sign

WeBuildStack is a remote-first software development company in Bengaluru, India, that builds web and mobile applications and the cloud behind them. For a multi-tenant product with billing, an admin console and the integrations B2B buyers ask for: a written quote within 48 hours and an MVP in six weeks with deployment included, with team hours set to your timezone. 15+ engineers, 100+ projects.

The plumbing every SaaS needs, done right the first time, so your team spends its weeks on the features that sell.

Problems we fix

Where SaaS projects usually stall

  1. An enterprise deal stuck because the product has no SSO, SCIM provisioning or exportable audit log.

  2. Tenant data separated by a single WHERE clause that one missed filter could leak.

  3. Billing that breaks the first time a customer upgrades mid-cycle or asks to pay by invoice.

  2. Weeks 2–5
