When I try to create an invoice my client is no longer visible

If your client / contract is missing when you try to create an invoice it’s probably because you have passed the end date of your contract. Select Invoicing, followed by Clients & contracts. You will then need to select your contract from the list and edit the contract to ensure that the end date is in the future. Once you have edited the contract details, select Save contract.
