Its really easy to change your invoice number, customer or supplier account number using Capewell Finance & HR.
To prevent duplicate record numbers being created you can only decrease the number of the record if you change the prefix.
Navigate to the Settings page by clicking on the link at the top right hand corner of the page.
Click on the tab marked Starting Number and you can set a new number or prefix for Customers, Suppliers or Invoices. As explained above the system won’t let you decrease the number unless the prefix changes.
