Use this guide to compare custom software and SaaS subscriptions for B2B workflows, ownership, integration, cost, and scalability.

When SaaS wins

SaaS is usually faster when your workflow fits the product, integrations are available, and you do not need deep ownership of the roadmap.

When custom wins

Custom software makes sense when workflows are unique, data models are proprietary, integrations are complex, or the software is part of your competitive advantage.

Hybrid approach

Apex often recommends a hybrid path: use proven SaaS where it fits and build the custom layer where your business truly differs.
