Reliable, evolving B2B and B2C marketplaces

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.

For B2C, Stripe Connect or Mangopay cover most needs (automatic split, escrow, integrated KYC).

For B2B or more complex financial flows, we also work with Lemonway, Adyen for Platforms or direct banking integrations depending on your model.

Complete operator back-office from the MVP: 360° view on a dispute, ability to act on a transaction, exhaustive logs, inter-party messaging.

Moderation can be human (internal operators), semi-automatic (user reports) or AI-driven (problematic content detection) depending on scale.

E-commerce manages one seller (you). A marketplace manages N sellers with split payments, seller onboarding, moderation, inter-party disputes, different legal liability.

The right instinct: don't launch a marketplace thinking "we'll complexify later". Foundations are laid at the start or paid for dearly later.
