You can apply directly to be a credit controller, as many large companies will train you on the job. The qualifications and experience you'll need will vary, but most employers will expect you to have:
- 3 to 5 GCSEs at grades 9 to 4 (A* to C), including maths, and sometimes college qualifications
- the ability to use spreadsheets and computerised accounts packages
- experience of office administration or customer service work
A qualification in bookkeeping or accounts can also be useful.
You may be able to move into credit control after getting experience in accounts, finance or debt collecting.
