The short answer
Buy when the process is standard and a product covers at least 80% of the need. Build when the process is what makes you different. For most growing GCC companies the answer is in between: buy the core platform or ERP, then build the few screens, workflows and dashboards that make it yours.
Key facts
- Standard processes such as payroll and accounting are almost always cheaper to buy.
- Differentiating processes are where custom software earns its cost.
- Integrations add cost and risk on both paths, so count them first.
- Compare total cost over three years, not the first invoice.
Six questions that decide it
Q1: Is this process what sets you apart?
If it is how you win customers or deliver better than competitors, lean towards building. If every company does it the same way, buy.
Q2: Does a product cover 80% of the need without workarounds?
If yes, buy it and adapt your process to the product rather than the reverse.
Q3: How many systems must it connect to?
List every integration. Each one adds cost, testing and risk whichever path you choose.
Q4: Does it fit the GCC?
Check Arabic and right-to-left support, local e-invoicing and tax fields, and where the data is hosted.
Q5: What is the three-year cost?
For buying: licences per user, price rises, configuration and support. For building: development, hosting, maintenance and change requests.
Q6: Who owns it after launch?
Software without an owner and a budget for change becomes the next legacy system, whether bought or built.
Build, buy, or configure and extend
| Option | Best when | Watch out for |
|---|---|---|
| Buy | The process is standard and a product fits most of it | Workarounds, licence growth, vendor lock-in |
| Configure and extend | The core is standard but a few steps are yours | Keeping extensions supported through upgrades |
| Build | The process is a competitive advantage | Ownership, maintenance and change budget |
Example: a field operations team works in a mobile app designed around its own workflow, and every job writes straight into the existing ERP. The company keeps its ERP and builds only the part that makes the team faster.
Common mistakes
- Deciding on gut feel or on one demo.
- Comparing first-year cost instead of three-year cost.
- Customising a bought product so heavily that upgrades break it.
- Building without a named owner and a budget for changes.

Frequently asked questions
Should we build or buy software?
Buy when the process is standard and a product covers at least 80% of the need. Build when the process is a competitive advantage. Many companies buy the core and build the parts that make it theirs.
What does configure and extend mean?
Buying a core platform or ERP, configuring it, and building a small number of custom screens, workflows or integrations on top of it.
How do you compare the cost of building and buying?
Compare total cost over three years: licences, price rises and support for buying; development, hosting, maintenance and change requests for building.
What should GCC companies check in off-the-shelf software?
Arabic and right-to-left support, local tax and e-invoicing fields, data hosting location and local support.
