Most businesses end up running a mix of ready-made tools and software made for them. The real decision is which part of your operation belongs on which side.
Accounting, payroll, email, a basic helpdesk: plenty of businesses run these the same way, and a mature product already handles edge cases you haven't met yet. You can start quickly, someone else maintains it, and the subscription is predictable.

When the work is yours.
When a core workflow is what sets your business apart, or the workarounds around a tool eat more staff time than the tool saves, software built for that workflow starts to make sense. You decide how it behaves and when it changes.
Fits the workflow, exceptions included
You carry the cost of building and maintaining it
Real control needs the code, data and accounts in your name
Weighing it up
Questions that usually settle it.
01
Does the awkward case fit?
Every tool handles the ordinary transaction. Ask how it copes with the exception your team meets every week: a split shipment, a booking moved twice, a client billed in two currencies.
02
How much work happens around the tool?
Count the spreadsheets, copy-paste steps and manual reminders that exist only because the tool can't do something. That effort is a real cost, even though it never arrives as an invoice.
03
Can you get your data out?
Check exports, API access and whether either is limited by plan. If you can't read your own records programmatically, connecting or replacing the tool later becomes harder.
04
Who controls change?
With a product, the vendor sets the roadmap and can change pricing or retire a feature you rely on. With custom software the decisions are yours, and so is the bill for every change.
05
Are you comparing like with like?
Put set-up, training, integration, workarounds and support on one side; build, hosting, maintenance and continued development on the other. Setting a licence fee against a build quote alone misleads in both directions.
06
Is this core or supporting work?
Software for the part of the business customers judge you on deserves more control than software for the part nobody outside ever sees.
You don't have to choose for the whole business. The answer that holds up best is often a mix. Keep the accounting package and the email platform. Connect them so nobody types the same data twice. Build a smaller application only around the workflow no product handles well, such as quoting with your own pricing rules or a portal for channel partners.
That middle route depends on the tools you keep offering proper integration access, so confirm each one has an API or export you're allowed to use on your plan. Our API integrations work covers that connecting layer, and the blog post on whether to build, buy or integrate walks through the decision in more depth.
If one of ours fits, try it first.
We build products of our own for a few common needs. Where one fits, it's worth a look before commissioning a custom build.
Can we start with a ready-made tool and build later?
Yes, and it's often the right order. Running on a product for a while shows you exactly where it falls short, which makes a later custom build much easier to scope. Keep your data exportable so the move stays possible.
Does custom software always give us more control?
Only if the arrangement says so. If the developer holds the code, the hosting or the domain, you have a custom product you don't control. Settle ownership of code, data and accounts, documentation and handover before work begins.
