Our commitment

We build B2B SaaS designed to scale without rework

A B2B SaaS poorly architected in MVP phase costs 5 to 10 times more to fix at scale. The wrong choices on multi-tenancy, data model or role management become structural blockers the moment the first large customers land.

At Inprogress, we know the specific traps of B2B SaaS: data isolation, complex billing, SSO and granular permissions, stable public APIs. We anticipate these concerns at scoping so you don't need a rewrite 18 months later.

Our responsibility

A B2B SaaS ready for your first enterprise customers

First large B2B customers are demanding: they audit your security, ask for SLAs, want clean integrations. A product not built for that loses them during sales cycles.

We take technical responsibility at the level expected by serious B2B buyers: security, observability, API documentation, controlled deployment processes. Not a rushed MVP, a real enterprise-ready product.

Multi-tenant isolation, audit logs, SSO, GDPR compliance: the product is ready for your most demanding B2B sales cycles.

Delivery speed

Short sprints, regular releases, observability in place: the product moves forward continuously without breaking production.

Frequently asked questions

Multi-tenancy (strict data isolation between clients), complex billing (plans, add-ons, prorata, upgrades), SSO and granular permissions, stable and versioned public APIs.

Each of these is addressed seriously from scoping, not improvised along the way.

We pick the isolation model that fits your context: shared schema, schema per tenant or database per tenant. Each approach has trade-offs on cost, performance and isolation.

For most early-stage B2B SaaS, shared schema with properly configured row-level security is the right balance.

One to two week sprints, continuous production releases, feature flags to test with select customers before general rollout.

The product team keeps a sustainable pace and your first customers see added value every sprint.

Audit logs enabled, SSO in place, documented GDPR policies, clear security architecture. We anticipate typical IT buyer questions so sales cycles don't get stuck on tech.

For enterprise targets, we also prepare elements for SOC 2 or ISO at the right phases.

Yes. We audit the existing codebase, identify risks (fragile multi-tenancy, patched billing, blocking tech debt) and propose a stabilization plan without freezing the roadmap.

We often work on SaaS in scale phase where early technical decisions have become problematic.
