MplusKASSA: introduction and use cases
What is the MplusKASSA integration?
MplusKASSA is a point-of-sale (POS) system for charging products on site — from a drink or catering to the hire of a lane or room. The integration with i-Reserve is two-way: a booking flows from i-Reserve to the POS (as a table/order), and whatever is added on site (extra drinks, catering or products) comes back into the booking after completion. This creates one complete financial picture and lets you invoice from i-Reserve.
This article is the introduction. The full behaviour is described in “What does the connection entail?” and the setup in “How do I set up the connection?”.
Two examples
Use case 1 — Bowling alley
- The guest books a bowling lane online and pays a deposit.
- On arrival the booking is ready in the POS.
- The guest orders drinks and goes bowling.
- At the end the drinks are paid at the POS.
- The total receipt syncs back to i-Reserve, so the booking is financially complete.
Optional: the accounting link can run from either MplusKASSA or i-Reserve.
Use case 2 — Meeting with catering
- The customer books a meeting room in advance.
- On arrival the booking is ready.
- A separate lunch is ordered on the day itself.
- Afterwards the extras are synced back to i-Reserve.
- The invoice comes from i-Reserve, including the catering.
