# Should you build your own loyalty app?

Build it yourself if loyalty is the thing you sell, or if you need something no product does. For a cafe or a shop it is almost never worth it. Building it is the cheap part. Keeping it working, year after year, is the part that never stops costing you.

Written 31 August 2026. This is about the shape of the decision rather than any
particular quote.

## Where building wins

**Genuinely unusual requirements.** If your programme does something no product
does, and that something is central to your business, buying will not fit.

**Loyalty as the product.** If the programme itself is what customers are paying
for, owning it entirely is defensible.

**You already have engineers.** The marginal cost of one more system is much
lower when the team exists.

## What the quote usually leaves out

**Maintenance forever.** Operating systems change, browsers change, payment
providers change their APIs. None of this stops.

**App store compliance.** Two stores, two review processes, two sets of policies
that change without asking you.

**Wallet certificates.** Apple and Google wallet passes require certificates and
integrations that expire and must be renewed. A lapsed certificate breaks every
pass at once.

**Payments and money.** Taking money brings obligations. Holding value customers
paid for brings more, and in some jurisdictions engages financial regulation.

**Security and privacy.** You are holding personal information. That obligation
does not scale down for a small business.

**The person who built it leaving.** The most common failure. A working system
nobody understands is worse than no system, because it fails at the worst
moment.

## The honest arithmetic

Compare a monthly subscription against paying a developer for a few days a year,
every year, forever. Then add the risk of it breaking on a weekend when nobody
can fix it.

For most hospitality operators that comparison is not close, and the reason is
not the build. It is that the build is the only part with an end date.

## When to revisit

If you reach the point where a platform is genuinely limiting something central
to your business, and you have engineering capacity. Until then, the calculation
does not change.
