Comparison of custom software and off-the-shelf SaaS
Consideration	Custom Software	Off-the-Shelf SaaS
Best fit	Workflows that set your business apart or that generic tools cannot model	Standard needs that an existing product already solves well
Upfront cost	Higher build investment, scoped after discovery. Share your requirements for an estimate.	Lower setup cost, with a subscription starting on day one
Long-term cost	No per-seat licence fees; hosting and support continue	Per-user fees tend to grow as your team and data scale
Time to launch	Phased: a focused MVP first, then further releases	Fastest when your process matches the tool’s defaults
Integrations	Connects to your CRM, ERP, payments and data as needed	Limited to the connectors the vendor supports
Control & ownership	Source code handed over under your project agreement	Vendor controls the roadmap, pricing and data formats
Trade-offs	Needs discovery, a delivery team and ongoing maintenance	Workarounds, feature limits and vendor lock-in
Our verdict	Choose custom if your process is your edge or tools need constant workarounds.	Choose off-the-shelf if a product already covers most of what you need.
