What is B2B Software?

Custom software is organization-level software designed to coordinate operations, manage transactions, process large volumes of data, and generate business-wide reports for large corporations or institutions.

How B2B Software works in production

Custom software must meet strict performance, security, and scaling standards. Unlike consumer applications, custom platforms handle thousands of concurrent users, manage large databases, and comply with strict regulatory frameworks. Building resilient business applications requires using decoupled API architectures and ACID-compliant databases.

The ERPStack approach to B2B Software

We build custom platforms using Next.js, PostgreSQL, and AWS. We focus on low-latency edge rendering, type-safe database queries, and automated testing to ensure your system remains stable at scale.

Frequently asked questions about B2B Software

What separates B2B Software from consumer software technically?

The unit of ownership. Consumer apps model 1 user; B2B Software models an organisation that contains users, with roles, delegated administration and data that outlives any individual account. That single difference forces multi-tenancy, Role-Based Access Control, audit trails and SSO into the foundations. Retrofitting an organisation layer onto a user-shaped schema is one of the most expensive migrations a product team can take on.

Why does B2B Software need audit logging so early?

Because the buyer's security review asks for it before the first renewal, not after. B2B Software that cannot answer who changed a record and when will fail a customer's vendor assessment regardless of how good the product is. An append-only journal written in the same transaction as the change costs very little on day 1 and is close to impossible to reconstruct later, since the history you needed was never captured.

How should B2B Software handle per-customer customisation?

With configuration and feature flags, not forks. Once 2 customers run different code, every release is tested twice and fixed twice. B2B Software scales by making the variable parts data — field definitions, workflow rules, entitlements — evaluated by 1 shared codebase. Feature Flags let a capability be enabled per tenant, which covers most genuine differences without branching the deployment.

What does ERPStack build differently for B2B Software?

We start from the tenant boundary rather than the screen. B2B Software here means Row-Level Security in PostgreSQL 18, Role-Based Access Control with per-tenant role definitions, SSO wired before launch, and an immutable audit trail behind every mutation. Those 4 pieces are what a customer's security questionnaire tests, and building them first is far cheaper than adding them during a stalled procurement cycle.
