# Custom software vs off-the-shelf: build or buy? > Off-the-shelf software is faster to start and cheaper upfront, and is the right choice when your process is standard, such as accounting, email or HR. Custom software costs more upfront but fits your exact workflows, avoids per-user fees and becomes an asset you own. Build when the process is your competitive edge or subscriptions grow costly; buy when it is not. Buy what makes you ordinary, build what makes you different. The hard part is knowing which is which. - **Off-the-shelf:** Low upfront, recurring fees - **Custom:** Higher upfront, asset you own - **Common pattern:** Buy for standard work, build the core - **Tool:** Build vs buy calculator - **Off-the-shelf:** The process is standard across businesses, a product fits most of your needs, and per-user costs stay reasonable as you grow. - **Custom software:** The process sets you apart, you are bending a product with workarounds, integrations are critical, or subscription costs will exceed the cost of owning. ## Comparison | Factor | Off-the-shelf | Custom software | |---|---|---| | Upfront cost | Low | Higher | | Ongoing cost | Per-user or per-transaction subscriptions | Hosting, support and enhancements | | Fit | You adapt to the product | Software adapts to you | | Speed to start | Fast | Slower | | Integrations | Whatever the vendor supports | Built exactly for your systems | | Control | Vendor roadmap and pricing changes | You decide features and priorities | | Ownership | Licence to use | You own code and data | | Risk | Vendor shutdown, price rises, lock-in | Depends on the quality of your build partner | ## A simple decision test 1. **Is the process unique to you?** If competitors run it the same way, buy. 2. **How many workarounds?** If people export to spreadsheets to finish their work, the product does not fit. 3. **What will fees cost at your scale?** Multiply per-user fees by future headcount over several years. 4. **How critical are integrations?** Systems that must talk to each other in real time favour custom.

Upfront, yes. Over several years it can cost less than subscriptions for many users, and it avoids the hidden cost of workarounds. Compare total cost of ownership. ### What if our custom software partner disappears? Own your code and repositories, insist on documentation and standard technologies, and you can move to another team. This is why code ownership matters. ### Can we combine both? Yes, and most businesses should: buy standard tools and build the parts that differentiate you, connected through APIs. ## Related guides - [Odoo vs custom ERP: which should your business choose?](https://infikeytechnologies.com/compare/odoo-vs-custom-erp): Odoo is a modular ERP with ready apps for accounting, inventory, sales, purchase and manufacturing, available as a free Community edition or... - [Salesforce vs HubSpot vs custom CRM: which fits your sales team?](https://infikeytechnologies.com/compare/salesforce-vs-hubspot-vs-custom-crm): HubSpot is the easiest CRM to adopt, with a free tier and strong marketing tools, ideal for small and mid-sized teams.
