One supply, one figure
Every wallbox sits behind the same meter. The building invoice ends in a single amount.
The charging current runs off the building supply, and the service charge statement needs one figure per parking space.
A card per tenantMeter readings from the stationMonthly figuresThe wallboxes in the car park hang off one shared building supply.
Each parking space belongs to a flat, each flat to a tenancy.
Tenants move in, tenants move out, spaces change hands.
The monthly statement has to follow all of that.
What it takes today is one figure per parking space, and that is the figure nobody has.
All three end up with the owner.
Every wallbox sits behind the same meter. The building invoice ends in a single amount.

Each tenant is issued a card of their own. The permission covers the car park.

The new tenant receives a card, released for the charge points of the building.
The wallbox asks CPIM and releases the socket for that card.
Start, end and meter readings of every session are written down.
The figures per card leave as a spreadsheet for the accounts department.
Matching a card to a tenant is the whole of the upkeep.

The charge points of one building form a charging group. Permissions apply to the group.
Add the new card, block the old one, done. Earlier sessions stay with the tenant who ran them.
Start and end readings are reported by the wallbox. They are the basis for your billing.
One line about the size of the building is enough for a first answer. A car park still at the planning stage can be costed too.
