When a business process outgrows spreadsheets, the first question is usually whether to buy a ready-made product or build something custom. Both can be the right answer. The trick is knowing which fits your situation.
When buying makes sense
- The process is common across many businesses, such as accounting, payroll or email.
- A mature product already covers most of what you need.
- You want to start quickly with predictable monthly costs.
- The process does not set you apart from competitors.
When building makes sense
- The process is how you win business, and doing it better is a competitive advantage.
- Off-the-shelf tools force awkward workarounds or duplicate data entry.
- You need to connect several systems in a way no product supports.
- Per-user licence costs grow faster than the value you get.
Look at the total cost, not the first invoice
Bought software has licences, configuration, integrations and the cost of changing how people work to fit the product. Custom software has design, development, hosting and ongoing maintenance. Compare both over three to five years, including the time your team spends on workarounds.
Consider the middle path
Many of the best solutions combine both: a standard product at the core, with custom integrations, portals or automations around it. You get the reliability of a proven product and the fit of a tailored solution.
Watch for the warning signs of a poor fit
Many businesses buy a product, then gradually build a web of spreadsheets, manual exports and email chains around it to fill the gaps. If staff spend hours each week copying data between systems, or if the product's limits are shaping how you serve customers, the true cost of buying is higher than the licence fee suggests. Equally, if a custom system needs constant fixes or only one person understands it, the true cost of building is higher than it looks. Be honest about both before you decide.
Ask the right questions
- How many people will use it, and how will that grow over three years?
- What happens to your data if the vendor is acquired, changes its pricing or shuts down?
- Can the product connect to your other systems through a documented API?
- How much of your process would you have to change to fit the product?
- Who will maintain a custom system once it is live?
If most of the answers favour flexibility, control and integration, building is worth serious consideration. If they favour speed, low maintenance and standard processes, buying is usually the better choice. Either way, involve the people who will use the system every day before you decide, because their workarounds reveal what really matters.
Reduce the risk of building
- Start with a small first release that solves the most painful problem.
- Deliver in short iterations with regular demos.
- Make sure you own the code and documentation.
- Plan for support and improvements after launch.
