Loyalty glossary

Updated 31 August 2026

Every term used in loyalty programs, defined plainly. The words below come up in every conversation about bonus cards, points and rewards, and they are used inconsistently often enough to be worth pinning down.

The mechanics

The rules a business can choose between, and what each one actually is.

  • Loyalty program — a standing rule that a purchase gives something back to the buyer.
  • Bonus — an umbrella word for anything earned by buying: points, a stamp, a reward.
  • Point — a unit of balance earned on a purchase and spent against a later one.
  • Stamp — a mark counting a visit or an item, where a full row earns a free item.
  • Tier or level — a rank earned over time that carries a benefit while it is held.
  • Cashback — a share of a purchase returned as value, expressed in money.
  • Coupon — a named one-time offer, claimed by a customer and redeemed once.
  • Referral — a reward paid for bringing a new customer who then buys.
  • Welcome bonus — a balance credited at signup to make the second visit likelier.

The numbers

The settings that decide what a program costs and whether anyone bothers with it.

  • Earn rate — how much spending produces one point.
  • Redemption rate — what one point takes off a later bill.
  • Give-back — earn rate multiplied by redemption rate: the true cost as a share of the sale.
  • Minimum redemption — the smallest balance that may be spent.
  • Expiry — the period after which unused balance is removed.
  • Threshold — the amount of lifetime earning that moves a customer up a level.
  • Liability — the total unspent balance a business owes its customers.

The measurements

What a business reads afterwards to decide whether the program is working.

  • Retention rate — the share of customers who come back in a given period.
  • Churn — the opposite: the share who stop coming.
  • At-risk customer — a regular whose gap since the last visit has grown well past their normal one.
  • Basket or average check — the amount spent per visit.
  • Visit frequency — how often a customer returns.
  • Redemption rate (of a campaign) — the share of issued coupons actually used.
  • Lifetime value — total margin a customer produces across the whole relationship.

The plumbing

Terms that come up once a program is connected to a till.

  • POS — point of sale: the cash register system where the bill is taken.
  • POS integration — the register talking to the loyalty platform directly.
  • Ledger — the append-only record of every point issued and spent, which is never edited.
  • Void — a cancelled bill, reversed on the loyalty side by a compensating entry.
  • Idempotency — the guarantee that a retried request does not award the same points twice.
  • Member card — the customer’s identity, shown as a QR code, a barcode or an NFC tap.

Common questions

What is the difference between a bonus and a point?

Bonus is the general word for anything a purchase gives back. A point is one specific form of it — a unit of balance with a defined value that is spent against a later purchase.

What does redemption mean in a loyalty program?

Spending what was earned: taking points off a bill, using a coupon, or claiming the free item at the end of a stamp card. Businesses also use the word for the share of issued coupons that get used.

What is loyalty liability?

The total balance customers have earned and not yet spent. It is money the business owes in goods, which is why expiry rules and minimum redemptions exist.
