B2B software is sold to procurement teams. Procurement teams care about three things: security review, vendor risk, and total cost of ownership. Software that passes procurement looks different from software that only sells to founders. SSO, audit logs, role-based access, data residency, custom contracts. This page covers what we build, what procurement actually asks for, and what it costs.

- Build (8 to 16 weeks). Two-week sprints. Demo every sprint with stakeholder. SSO and audit-log testing every sprint.
- Procurement and compliance UAT (2 weeks). SSO testing with Okta, Azure AD, OneLogin, Google Workspace. SCIM provisioning testing. SOC 2 evidence collection. Pen-test.

Tech stack
Default B2B stack. Each layer chosen for enterprise procurement readiness.
- Front end. Next.js with TypeScript. Tailwind CSS plus shadcn/ui. WCAG 2.2 AA accessibility (required for many US public-sector buyers).
- Back end. Node.js (Fastify) or Python (FastAPI). Multi-tenant request handling with tenant context injection. Idempotency on writes.
- Multi-tenancy. PostgreSQL with Row Level Security (RLS) for shared-schema multi-tenancy. Schema-per-tenant where stricter isolation required. Database-per-tenant for enterprise tier.
- Auth and SSO. Auth0 or Clerk B2B for SAML 2.0, OIDC, OpenID Connect. SCIM 2.0 for user provisioning. JIT (just-in-time) provisioning on first SSO login.
- Billing and contracts. Stripe Billing for subscription. Stripe Invoicing for net-30 enterprise contracts. Salesforce CPQ integration where required.

- Compliance. SOC 2 Type II readiness with Drata or Vanta. ISO 27001 architecture. GDPR DPA support. HIPAA where the buyer requires it.
SOC 2, GDPR, and procurement readiness
We build SOC 2 Type II architecture from day 1 with Drata or Vanta integration for automated evidence collection. We do not file the SOC 2 report ourselves; we deliver the architecture and evidence that supports your audit firm. GDPR DPA support, HIPAA architecture where required, immutable audit logs, and encryption at rest are standard on B2B builds.
