SaaS Development Company

The architectural decision that most defines a SaaS product is how tenants are isolated from each other — a shared database with tenant-level filtering, or a separate database per tenant. We most often build this on the ABP.IO framework, which handles tenant resolution and data isolation natively, saving the significant infrastructure work of building and testing that isolation layer by hand. Which isolation model fits depends on the compliance and data-sensitivity requirements of the product, not a one-size-fits-all default.

Erudite Solutions builds and maintains TrueFin, a cloud accounting and financial management platform for SMEs, NGOs, and project-based organizations. Building our own SaaS product means we work with the same multi-tenancy, billing, and long-term maintenance concerns we advise clients on, rather than only having theoretical experience with them.

A SaaS product's frontend needs to handle authentication, subscription state, and role-based access on top of the core product features. We build these frontends with Angular or React depending on the project and team, connected to a .NET backend that handles the multi-tenant business logic.

Beyond the core product, a SaaS platform needs a smooth path for onboarding new customers — including migrating existing data where a customer is switching from another system — and subscription billing that handles plan changes, trials, and payment failures without manual intervention. We also make sure the product works consistently across desktop, tablet, and mobile, since SaaS customers expect to access the same account from whichever device is in front of them.
