A credit controller makes sure the business gets paid. They assess whether a customer should be given credit, monitor what is owed, chase overdue accounts and decide when an account should be handed over. It is a finance role that runs almost entirely on conversations.
This guide sets out credit controller duties and responsibilities and how the role changes by sector. It sits in the IT, finance and professional duties cluster, part of the wider job duties guide.
What Does a Credit Controller Do?
A credit controller opens and vets accounts, sets and reviews credit limits, allocates receipts, works the debtors age analysis and collects overdue money by phone and email. They also release or hold orders when an account is over its limit or past terms.
The skill in the role is separating the customer who cannot pay from the customer who has not paid. Many overdue invoices are administrative rather than financial: a missing purchase order number, an unmatched credit note, an invoice sent to the wrong person. A good credit controller finds and fixes those quickly, which frees the time to deal properly with the accounts that are genuinely at risk.
The role also sits in permanent tension with sales, which wants the order released. That tension is the point: the controller is the person accountable for whether the sale ever turns into cash.
Credit controller job descriptions divide into two halves that are easy to confuse: the ledger work of allocation, reconciliation and statements, and the decision work of limits, order release and handover. The second half is what distinguishes the role from a debtors clerk position and is where employers expect judgement rather than process.

Credit Controller Duties by Workplace or Industry
Wholesale and Distribution
Large trade debtor books, order release decisions made daily, and constant reconciliation of rebates, returns and short deliveries.
Manufacturing and Industrial
Fewer, larger accounts with longer terms, retention amounts and disputes tied to delivery documentation or quality claims.
Services and Professional Firms
Collections often turn on scope disputes, so the controller works closely with the person who delivered the work to resolve the query before chasing payment.
Consumer Credit
Collections from individuals are governed by the National Credit Act, which regulates affordability assessment, disclosure and collection conduct, so procedures are far more prescribed.
Across every sector the controller is measured on the same three numbers: debtor days, the value sitting beyond terms, and bad debt written off. A collections record that improved all three is the strongest thing you can put on a CV for this role.

Frequently Asked Questions About Credit Controller Duties
What are the duties of a credit controller?
Opening and vetting new accounts, setting and reviewing credit limits, working the debtors age analysis, collecting overdue amounts by phone and email, allocating receipts, reconciling accounts, resolving invoice disputes, releasing or holding orders, negotiating payment arrangements, handing over accounts and reporting on debtor days.
What is the difference between a credit controller and a debtors clerk?
A debtors clerk processes and reconciles the ledger. A credit controller does that too but also carries the decisions: credit limits, order release, payment arrangements and when to hand an account over.
What qualifications does a credit controller need?
Matric with accounting is the usual base, and a credit management certificate or diploma is valued. Experience on the specific accounting system and a demonstrated collections record often matter more.
Can a credit controller refuse to release an order?
Within the credit policy, yes, and that authority is the point of the role. The policy should state the limits and who may override them, so that the decision is not settled by whoever argues hardest.
Duties vary by employer and sector, and collections from individual consumers are regulated by the National Credit Act. Check your job description and your employer’s credit policy.
