Loyalty software: seven hidden costs beyond the licence

What to take away

Reward funding sits outside the software quote

A loyalty platform prices the mechanism, not the reward. Cash leaves somewhere, whether points come from margin, a partner contribution or a marketing budget.

A retailer issuing points worth 1.5% of a £60 basket hands over 90p per transaction before any platform fee — an illustrative example, not a benchmark. At monthly volume, that dwarfs most subscription tiers. Read the wider cost picture in the loyalty marketing costs and budget guide for England before signing anything.

Breakage assumptions flatter the business case

Breakage is the share of points never redeemed. Finance teams like it because it turns a liability into income. The risk is assuming a rate you cannot support.

If you assume 25% breakage and actual redemption runs at 90%, the shortfall lands in the next financial year. The points liability itself is deferred revenue: IFRS 15, which replaced IFRIC 13, governs it for IFRS reporters, and FRS 102 applies under UK GAAP, so the balance stays on the books until the points are redeemed or expire. Ask the vendor what evidence backs any redemption forecast, and test two redemption rates. Scheme terms and expiry rules are also part of the regulated consumer relationship, covered by the Digital Markets, Competition and Consumers Act 2024.

VAT treatment on rewards and fees

VAT is where loyalty schemes get quietly expensive, and it is the line finance teams most often miss when they price the loyalty software alone. Points issued with a sale can be treated as a discount, changing the VAT you account for, and HMRC's published guidance on discounts and vouchers sets out how that treatment is decided. Third-party rewards bought in and passed on create a different position.

Your accountant needs to see the reward flow, not just the software invoice. Assume the subscription, the reward purchase and any fulfilment charges are three separate VAT events until told otherwise.

Data hygiene and consent maintenance

A loyalty database decays. Addresses go stale, consent records need refreshing and duplicate accounts need merging. That work is required under UK GDPR and PECR, and the Information Commissioner's Office expects you to be able to evidence it, but it is rarely in the subscription. A scheme with 40,000 members might need a part-time data administrator at roughly £1,800 a month — an illustrative figure, not a rate card.

The same clean-up feeds audience research: the leisure and tourism datasets from the Office for National Statistics show whether the behaviour you reward is still happening, so consent maintenance is what keeps reward spend pointed at real customers.

Integration and platform migration work

Linking a loyalty platform to ecommerce, EPOS and CRM is project work, not configuration. Budget development days, testing time and dual running; switch provider later and you pay again, perhaps to extract your own member data.

Every connector, feed and payment integration is its own line item, so ask for the integration scope in writing, with the development days it assumes, before signature rather than after the first invoice.

Referral rewards and fraud control

Referral schemes pay out on an action a stranger controls, while self-referral, duplicate accounts and voucher abuse cost money. Fraud tooling is sometimes a paid add-on; manual review is a salary cost.

Budget for both, and decide in advance what evidence voids a referral reward. The pricing models comparison for England explains how reward-funded and subscription-funded contracts shift that risk between you and the vendor.

Contract exit and data extraction fees

Notice periods, minimum terms and data export charges are the costs nobody reads until they leave. Check whether your member list leaves with you in a usable format, and what that costs. Check whether the notice period spans a peak trading season. These clauses are negotiable before signature and rarely afterwards.

Glossary

Common questions

Are hidden costs the same across the UK?

Consumer protection rules under the DMCC Act 2024 apply across the United Kingdom, so scheme terms and expiry practices face the same framework in England, Scotland, Wales and Northern Ireland. Commercial terms differ by vendor, not by nation.

How much should I hold back for unexpected costs?

There is no published benchmark. As a labelled illustrative example, a team paying £2,000 a month for software might hold back 20% to 30% of total programme budget for reward funding, data work and integration.

Can I avoid exit fees by choosing the right contract?

Sometimes. Ask for data portability and a notice period you can live with before you sign. If a vendor will not commit in writing, treat that as a cost you are accepting.

Does a referral scheme cost less than a points scheme?

Not necessarily. Referral rewards are paid per successful action, which can be cheaper at low volume. Fraud control and manual review add cost as volume grows.
