What changes in a credit controller’s day when AI agents arrive?

Chasing and cash allocation move to the agent. A credit controller's day shifts towards the decisions that affect customer relationships: disputed invoices, account stops on important customers, credit limit changes and payment plans for business customers in difficulty. They also become the check on what the agent did alone, such as unapplied cash and reminder sequences.

What did the day look like before?

In a business-to-business finance team, a credit controller typically:

• allocated incoming payments against open invoices;
• sent statements and reminder emails in sequence;
• phoned customers with overdue balances;
• logged disputes and passed them to sales or operations;
• put accounts on stop and released them;
• reported aged debt to the financial controller.

A large share of the day went on allocation and routine chasing.

What does the agent take on?

What fills the controller's day now?

Unallocated and misallocated cash. Payments without clear remittance are held. The controller resolves them using the customer's remittance advice, which is signed by the payer, and the open items in the ledger, which are sealed. A customer's email saying "this covers everything" is declared, and rarely true.

Disputes. The agent logs and routes them; the controller makes sure they are resolved, because an unresolved dispute is a debt that never gets paid.

Account stops. Stopping supply to a long-standing customer is a commercial decision with consequences for sales. The agent drafts the stop when the business's own limits are breached; the controller decides, often after talking to the account manager.

Credit limits. The agent proposes changes based on payment behaviour and external credit data. The controller weighs them with what they know about the customer.

Sequence quality. The controller checks that the agent's reminders went to the right contact, at the right stage, with the right tone. A reminder sent to a customer with an open dispute damages trust.

A day in practice

Take a building supplies wholesaler. Overnight, the agent allocated most of the day's receipts, sent 400 reminders and drafted stops on six accounts. The controller starts with 25 held allocations. One is a payment of 18,400 from a contractor with a remittance that lists invoices adding up to 19,000; a credit note for 600 is missing from the ledger. She checks with the sales team, confirms the credit note was agreed, has it raised, and allocates the payment.

Of the six draft stops, she approves four. One customer has a dispute over a delivery the agent had logged but not linked to the overdue invoice; she declines the stop and chases operations. The last is the wholesaler's third-largest customer. She calls the account manager, who agrees a firm conversation instead, and records the reason. In the afternoon, she samples the agent's reminders and finds three sent to a contact who left the customer business last month. She updates the contact and asks the process owner to make reminders stop when an email bounces.

What does a credit controller need to learn?

Reading the record behind each held item. Telling sealed ledger data from declared customer claims. Judging when a commercial relationship outweighs the business's standard limits, and recording why. Spotting patterns in the agent's work that need a correction rather than another manual fix.
