For: Operators and account owners managing fleet charging costs in Monta Hub.
Cost centers let you group charging costs by department, project, vehicle pool, or any unit you reconcile spend against. Once you tag your drivers, vehicles, charge keys, or accounts with a cost center, every charge is automatically attributed to the right bucket — no manual sorting needed.
Where to find cost centers
In Monta Hub, go to Finance > Cost centers.
Create a cost center
Click New.
Fill in:
Name — a human-readable label (e.g. "Fleet Operations"). Must be unique within the operator.
External ID — your billing-system reference code (e.g. "FLEET-001")
Click Create.
Assign a cost center
Assign a cost center to the entities whose charges should be attributed to it:
Members (account members)
Member profiles
Vehicles
Charge keys (RFID tokens)
Accounts (including nested accounts)
To assign in bulk: select multiple rows in the relevant list (for example, Fleet Management > Members), then click Assign cost center.
To assign individually: open the entity's detail page and update the Cost center field.
Cost centers are scoped per account. When bulk-assigning, select rows from a single account only.
How charge attribution works
When a charge starts, Monta automatically resolves which cost center to attribute it to, using this priority order:
Charge key (RFID token) — highest priority
Member (the driver who initiated the charge)
Member profile
Vehicle
Account (the paying account)
No match — charge has no cost center attribution
The resolved cost center is stored on the charge. You can see it in the Cost center ID field on any charge's detail page.
Edit a cost center
Open the cost center from Finance > Cost centers, hover your cursor over the cost center you want to update and select Edit.
See what is assigned to a cost center
Open the cost center's details page to see every entity assigned to it.
Go to Finance > Cost centers.
Select the name of the cost center.
The details page shows the cost center's External ID, Level (Operator or Account), Created date, and ID.
Below these details, a table lists everything assigned to the cost center. It has three columns:
Name — the entity's name. Select it to open the entity.
Type — Member, Member group, Charge key, Vehicle, or Account.
Account — the account the entity belongs to. Select it to open the account.
To find a specific entity, use the search field. To show only some entity types, use the Type filter.
If nothing is assigned yet, the table shows "No assignments yet."
Delete a cost center
Open Finance > Cost centers, hover your cursor over the cost center you want to remove, and select Delete.
A cost center cannot be deleted while entities still reference it. Remove the cost center assignment from all members, vehicles, charge keys, and accounts first.
To see which entities still use the cost center, open its details page.
Historical charges retain the cost center's external ID for accounting integrity. Future charges will no longer be attributed to the deleted cost center.
Review costs by cost center in the Fleet cost overview
The Fleet cost overview dashboard on an account includes a Grouped by cost center table. It shows what each cost center spent in the selected period.
To open it, open the account, select the Overview tab, then select Fleet cost overview.
For each cost center, the table shows the number of sessions, energy, spend, rate, currency, and estimated CO2 saved. The cost center with the highest spend is listed first.
Sessions without a cost center are grouped under Unassigned. The table follows the same charging type, roaming, and AC/DC filters as the other tiles on the dashboard.
Only sessions on the account's own charge points carry a cost center in this table.
If you don't see the Grouped by cost center table, the updated dashboard is not yet turned on for your account.
