Design cost centres, budgets and rules

Let the customer administer it themselves

Delegating cost centres, budgets and approvers to the customer's admin.

Procurement data belongs to the buying company. Every week you spend maintaining it is a week their Einkauf spends emailing you instead of ordering. Handing it over is the goal, not a concession.

Before you begin. Do not delegate on day one. Set the structure up yourself, run it for a month with real orders, then hand it over. A customer admin who inherits a working model maintains it; one who inherits an empty screen builds something you will have to unpick.

Why this matters more than it sounds

A mid-sized customer reorganises constantly in small ways. Someone joins the workshop. A cost centre is retired at the end of the year. A budget is topped up in March. A site manager leaves and their approvals need a new owner by Monday.

If every one of those is a ticket to your Innendienst, three things happen: the changes are late, the data drifts out of line with their ERP, and your team owns a workload that grows with every customer you sign. The customers who use the shop hardest are the ones who change the most.

What the customer's admin may change

The admin role on a contact runs their own organization: its people, their roles, and its master data. In procurement terms that means:

They ownWhy
Cost centres — creating, renaming, retiringIt is their chart of accounts. It changes when their ERP does
Owners and deputiesThey know who is on holiday. You do not
Personal spend limitsTheir internal authority, granted by them
Contact roles — who requests, buys, approvesSame
Budget amounts, and manual adjustments in-yearTheir money
The approver named on their own rulesTheir policy

Every one of those is a change the customer can make correctly and you cannot make quickly.

What stays with you

You keepWhy
Whether the apps are installedA platform decision — see Apps and the Marketplace
Restrictions that reference your catalogueProduct, category and catalogue restrictions point at your data. A customer admin cannot see your category tree and should not be guessing at it
prevent rulesA hard stop refuses orders. That is a commercial decision with your revenue on the other side of it, and it belongs in a conversation
The ERP mappingThe cost centre reaching the invoice is an integration you own — see Field mapping
Number ranges and order settingsYours, not theirs

The line is consistent: the customer owns their policy, you own anything that touches your catalogue, your revenue or your systems. When a request does not fit that line cleanly, it is usually a sign the customer wants something modelled differently rather than something delegated.

Hand it over

  1. Confirm the structure is complete and has survived a month of real orders.
  2. Set the admin role on the one or two people at the customer who will own it — their Einkaufsleiter and a deputy. Not five people. See Contacts and roles.
  3. Walk them through the three things they will actually do: add a person, move an owner, top up a budget. Not a tour of every screen.
  4. Give them the escalation path in writing: what to change themselves, and what to ask you for.
  5. Agree a review — once a quarter is enough. Fifteen minutes reading the cost-centre list and the approver list together catches almost everything before it becomes a support case.
Two admins minimum, and never a shared login. A single admin at the customer is a single point of failure that ends with somebody sharing a password, which destroys the audit trail that the whole area exists to produce.

Audit of their changes

Delegation only works if it is visible. Two trails cover it:

  • Budget movements — every reservation, confirmation, withdrawal and manual adjustment appends an entry carrying the amount, the reason and the person. A budget that was topped up by €5,000 in March shows who did it. See Reading the budget ledger.
  • People and roles — changes to contacts land on the customer timeline. See Customer activity.

What you should actually look at, rather than everything: manual budget adjustments and approver changes. Those are the two that can quietly undo a control. A limit raised for a shutdown and never lowered, or a budget topped up every month by the person who spends it, are the patterns worth a phone call.

What to check

  • Have the customer's admin make one real change while you watch — adding a deputy is a good one. If they cannot find it, the handover was a demo, not a handover.
  • Confirm they cannot change anything on the list you kept. An admin who can set a prevent rule will eventually set one on a Friday afternoon.
  • Look at the ledger a month later. If every entry is still yours, the handover did not take.
