Custom software or an off-the-shelf app: how to decide
A ready-made app is cheaper to start with and often enough. Custom software earns its place when the gaps cost you hours every week. Here’s how to tell which one you need.
Start with what already exists
An off-the-shelf app has real advantages. You can start today, you pay a subscription instead of a build, and the vendor handles updates. If the way you take bookings, send invoices or run a simple shop is much like everyone else’s in your field, a good app set up properly is usually the right answer.
So before you think about building anything, give the existing options a fair try. Check what the apps you already pay for can do, and whether a setting or an add-on closes the gap.
Signs you’ve outgrown it
- There’s a spreadsheet next to the appYour team keeps one because the app doesn’t track something you need.
- The same information gets typed into two or three placesAnd the copies drift apart.
- You’ve bent the way you work to fit the appAnd customers or staff feel it: a booking rule you can’t set, a report you build by hand every month.
- You pay for several subscriptions that don’t talk to each other
- You’ve outgrown the notebook or the shared calendarBut the big systems are built for companies ten times your size.
One of these on its own is a nuisance. Several together, every week, is usually a cost worth adding up.
What custom software gives you
- Your rules, built inLimits on places, booking windows, how credits work, who can do what. The software follows the way you work.
- Connected to what you keepIt links to the accounting, payment and calendar tools you already use, where they allow it, so nothing gets typed twice.
- Working where you need itOn the desk computer, on staff phones, and offline where that matters.
- Your data and codeThey belong to you, and you can take them with you.
What it costs, in plain terms
Custom software costs more up front than a subscription. It also needs hosting, updates and someone to fix it when something breaks. It pays off when it saves hours every week, replaces several subscriptions, or lets you work in a way no app supports.
It doesn’t have to arrive all at once. Built in phases, the first phase covers the job that costs you the most time, and your team uses it while the next one is built.
A middle way
You don’t have to choose one or the other for the whole business. Often the best answer is to keep the off-the-shelf tools that work, such as your accounting software, build only the missing piece, and connect the two.
Questions to decide with
- Is the way you work much like everyone else’s in your field, or is it part of why customers choose you?
- How many hours a week go into workarounds, double typing and manual reports?
- How many subscriptions would one system replace?
- Does it need to work offline, or on staff phones as well as the desk computer?
- Who owns your data today, and could you take it with you if you switched?
If most of your answers point to “like everyone else”, start with an app. If they point to hours lost every week and rules no app supports, custom software is worth pricing.
Example: B-Strong
B-Strong is a fitness studio in Serbia, and we built its system around the way it runs. The front desk works in a desktop app for Windows and Mac. Check-in, member records and payments keep working when the internet drops, and the Windows app updates itself.
Members carry their membership card in a phone app, as a QR code that changes every 30 seconds. They book individual, semi-private and group sessions, each with a set number of places, and next week’s sessions open on Sunday morning. Cancel at least 12 hours ahead and the credit comes back. These are the studio’s own rules, built in instead of worked around.
Not sure which side you’re on?
Our Digital Audit answers exactly this. If an existing app does the job, the roadmap says so and names it. If something needs building, you get a rough cost and time estimate for each step before you commit to anything.
