How do I add a missing bill or supplier to prepayments?

The best way to ensure full synchronisation with your accounting system is to add any missing supplier invoices directly to the accounting system as a new bill or ensure that you have turned on bank transactions in your Expense Journal Settings.   See How to Include All Expenditure (Not Just Bills) in Your Cost Recognition Reports. 

If, however, you wish to add a bill manually in ScaleXP (for example, to reflect a bill issued prior to your import start date), you can do this easily from within Journals/Prepaid Expenses.

To add a manual adjustment (not missing cost), see How to Add a Manual Adjustment to Costs.

To add a manual bill, go to any expense page and click on the three dots (top right), then Add Manual Bill.

From here you can select an existing supplier or create a new one.  

To add a bill to an existing supplier, you can also click on the existing supplier and then "Add Manual Bill".
