Stamp cards – setup

How to create a digital stamp card, for example "Buy 10, get 1 free" – which items earn stamps, what the reward is, expiry and campaigns.

Owner/manager Back office Last updated 09.10.2026

A stamp card is a loyalty programme: the customer earns stamps when buying certain items, and gets a reward when the card is full, for example a free coffee. Stamps are collected digitally on the customer, in both the webshop and the till, and the reward is deducted automatically as an ordinary discount.

Before you start

  • Stamp cards must be switched on for your shop by Cmerce.
  • You need the «Opprette og redigere stempelkortprogrammer og kampanjer» (Create and edit stamp card programmes and campaigns) permission. To adjust stamps on a customer you need «Justere stempler manuelt på et kundekort» (Adjust stamps manually on a customer card).
  • Stamps are tied to a registered customer. In the webshop the customer must be logged in. The walk-in customer (Kontantkunde) and guest checkouts earn neither stamps nor rewards.

How to do it

  1. Go to «Salg» (Sales) → «Stempelkort» (Stamp cards) and create a new programme.
  2. The «Opptjening» (Earning) tab:
    • Give the programme a «Navn» (Name), and optionally add extra terms in «Vilkår (tilleggstekst)» (Terms, additional text).
    • Choose «Kanaler» (Channels): «Nettbutikk» (Webshop) and/or «Kasse» (Till).
    • Choose the «Opptjeningsmodus» (Earning mode): «Per vare» (Per item), «Per kjøp» (Per purchase) or «Per beløp» (Per amount – then fill in «Kroner per stempel», kroner per stamp).
    • Under «Varer som gir stempler» (Items that earn stamps), add rules with «Ta med» (Include) or «Utelat» (Exclude) for products, variants, categories or brands. An empty list means all items count, and «Utelat» always beats «Ta med».
    • Choose whether «Rabatterte varer gir stempel» (Discounted items earn stamps), and optionally «Minste enhetspris for stempel» (Minimum unit price for a stamp), customer groups and «Velkomststempler» (Welcome stamps) for new customers.
  3. The «Belønning» (Reward) tab:
    • «Stempler for belønning» (Stamps for reward) – how many stamps the card needs.
    • «Når kortet fylles» (When the card is filled) – «Gjelder allerede i kjøpet som fullfører kortet» (Applies in the purchase that completes the card) or «Gjelder fra neste kjøp» (Applies from the next purchase).
    • «Belønningstype» (Reward type) – «Gratis vare» (Free item), «Kronerabatt på vare» (Amount off an item), «Prosentrabatt på vare» (Percentage off an item), «Kronerabatt på hele kjøpet» (Amount off the whole purchase) or «Gratis gave (egen vare)» (Free gift, separate item).
    • «Maks verdi på belønning» (Maximum reward value) and «Hvilken vare blir gratis» (Which item becomes free): «Billigste kvalifiserte vare» (Cheapest qualifying item) or «Dyreste kvalifiserte vare» (Most expensive qualifying item).
    • Choose whether the reward is applied automatically in the webshop and at the till.
  4. The «Utløp» (Expiry) tab: set when stamps expire (months without activity), when the reward expires (days), and «Maks stempler per kunde per dag» (Max stamps per customer per day). Empty fields mean no expiry.
  5. Save.

Campaigns

Open the programme and add a «Ny kampanje» (New campaign) to give extra stamps for a period, for example double stamps at weekends. You can set «Multiplikator (x)» (Multiplier), «Bonusstempler per kjøp» (Bonus stamps per purchase), channels, weekdays and start/end.

Viewing and adjusting a customer's stamps

  1. Go to «Kunder» (Customers) → «Kunder» and open the customer.
  2. Under «Stempelkort» you see stamps, available rewards and status. «Stempelhistorikk» (Stamp history) shows every change.
  3. Click «Juster stempler» (Adjust stamps), enter the number (negative to remove) and a reason.

Good to know

  • Terms are frozen per card. The number of stamps required, the reward and the expiry rules are copied to the customer's card when it is created. If you change the programme, it only applies to new stamps and rewards – an existing card never gets worse. Changes to which items earn stamps apply going forward.
  • If you deactivate the programme, no new stamps are earned. Rewards already given can still be used until they expire.
  • The terms are shown to the customer on the product page, in the basket, under «Min konto» (My account) and via a link on the receipt.
  • Returns: If the customer returns items, the stamps are taken back. If the reward has already been used, the stamp balance can go negative and is carried into the next card. The customer never has to pay anything back.
  • Training mode gives neither stamps nor rewards.
  • No reminder is sent to the customer before stamps or rewards expire.

Frequently asked questions

Can I have several stamp cards at the same time?

Yes. Create one programme per stamp card, for example one for coffee and one for lunch.

The customer forgot to identify themselves at purchase. Can I give the stamps afterwards?

Yes, with «Juster stempler» on the customer. Write a short reason without personal data.
