What does a prepaid package actually change?
A prepaid package is simple: the customer buys a block of visits at once, usually at a small discount, and draws them down over weeks or months. Groomers sell five baths. Detailers sell a season. Studios sell ten classes.
Three things change the moment they pay:
- You are paid before you do the work. For a business where the van, the products and the fuel come out of your pocket first, that is the difference between buying stock and waiting to.
- The next visit is already decided. A customer holding four unused washes is not comparing you to the place down the road.
- You now owe something. This is the part people forget. Unredeemed visits are a liability, not revenue, and if you do not track them you cannot answer the one question that matters at year end: how much service have I already been paid for and not yet delivered?
Why does prepayment make people come back?
Part of it is plain economics — they have already paid, so the marginal cost of the next visit is zero. But research on subscription and prepaid contracts suggests the economic benefit is only part of the story. Work out of Wharton on subscription programmes found that roughly two-thirds of the increase in customer purchases was not explained by the economic benefit of the programme itself, pointing instead at commitment and habit effects.
The sunk-cost literature points the same way: having paid up front, people are more likely to show up in order to not waste what they have spent. Researchers at Berkeley’s Haas School have examined exactly this in the design of prepaid contracts.
The trade-off nobody mentions
Here is the honest part. Prepaid is not strictly better than pay-as-you-go. The research on contract design finds a genuine tension: prepaid contracts attract more customers, but postpaid contracts tend to produce higher goal completion. Paying at the end keeps a small ongoing pressure to turn up that disappears once the money is already gone.
In practice this means a prepaid package sells well and then quietly goes unused, which feels like profit and is actually an unhappy customer with four baths they never took. The fix is not to stop selling packages. It is to notice when someone has stopped drawing one down, and get in touch while there is still goodwill left.
How should you price one?
A discount of 10–15% against the single-visit price is typical and enough to make the block feel worthwhile without giving away the margin that made you sell it. Keep the arithmetic obvious — five baths at $120 rather than $118.50 — because a package the customer cannot verify in their head is a package they do not trust.
Whatever you decide, the terms should be fixed at the moment of sale. If you raise your prices in March, the person who bought five washes in January still has five washes. Returnpass locks the package details onto each pass when it is issued for exactly this reason.
Is it worth it?
Reichheld and Sasser’s 1990 Harvard Business Review study remains the clearest answer on why retention pays: cutting the defection rate by 5% raised profits by 25% to 85% across the businesses studied, and by 30% in an auto-service chain. Note that the widely-repeated “25% to 95%” version of that figure is a later distortion — the real range is 25% to 85%.
How Returnpass handles it
Every prepaid pass counts down in the customer’s Apple Wallet, and your dashboard shows prepaid visits remaining — the service you have been paid for and still owe. The ledger behind it is append-only and exportable, so the figure survives an accountant asking where it came from.
