I have missed line item/s when matching/synching and/or matched the wrong billable.

You can manually populate the paid information.  You will need the following information:

The date ACC paid and the amount they paid.

Click into the affected billable, then EDIT then ADVANCED EDIT.

Enter only the date ACC paid and the amount paid, then SAVE

Once you have done this, go to REPORTS, enter the date ACC paid in BILLABLES PAID in the filter section, then APPLY.

If you have only the one item that needs “paying”, filter down using the billable ID.

Once you have the correct billable item, tick and MARK PROVIDER PAID.  If you are adding this into an existing pay round and you have already done the tax invoices, go to GENERATE BCIs, and tick REGENERATE.
