There are three options for writing checks, Full Payment of Invoices, Partial Payment of Invoices, and Write Occasional Checks. You must use either the Full Payment or Partial Payment options to pay invoices which which you have entered into the invoice database.
Occasional checks are basically, ``one-time'' checks. Occasional checks are intended for payments which are not related to invoices stored in the invoice Database. Paying an invoice that you have entered into the invoice database with a Occasional check will not cause the invoice to reflect the payment and the balance of the invoice will not be reduced. If you pay invoices from the invoice Database with an occasional check, the invoice will not be marked as paid in the Database and you may accidentally pay it a second time.
Although either type of check can be made written to Vendors who are stored in your Vendor database, only the Full and Partial payment options can be used to pay invoices that are stored in the database. Only Occasional checks can be written to payees who are not stored in your Vendor database. Hold the cursor over the occasional check menu item to see a short help explanation of this item.
DO NOT USE Write Occasional Checks to pay invoices which are stored in the invoice Database. Use either the Full or Partial Payment of Invoices options to pay invoices that are stored in the Invoice Database. This will cause the selected invoice(s) to be marked as paid in the Database.
