One loyalty programme. Every store, every channel.
The same member, the same prices and the same points in store, online and in the app. Custas is the promotions and loyalty backbone your POS, e-commerce and CRM all plug into.
one engine
What a chain needs that a plugin can’t give you.
Fast enough for Saturday
A basket is priced in under 5 ms at the 95th percentile, measured end to end, against a 250 ms budget. The queue doesn’t notice.
Campaigns that combine predictably
Explicit stacking and priority rules, so central marketing and local stores can’t accidentally double-discount.
A million codes in a batch
Unique single-use codes, guaranteed free of duplicates and look-alike characters, for print, email or partners.
Teams with the right access
Owner, admin, operator and viewer roles, two-factor sign-in, and an audit log of every change, reveal and export.
Links on your own domain
On Enterprise, short links and unsubscribe links go out on your own domain, and links you bring from Rebrandly or Bitly keep their codes.
Nordic from the start
Swedish, Finnish, Norwegian and Danish ID numbers. Templates in Swedish, Finnish and English, and Kivra-ready receipts.
The vendor review, answered before you ask.
Large customer databases attract regulators and attackers alike. Custas is designed so a single bug, a leaked key or a curious employee can’t turn into a breach.
