In Sage 100 Contractor, if I pay someone with a manual check through the 1-1 General Ledger Checks menu, and didn’t enter in a vendor in the vendor field, and they end up becoming one, how can I ensure their 1099 is accurate? In the 4-4 Vendors menu, select Options, and then select 1099 Balance/Startup Adjustment. Enter in the information in the Startup/Adjustment Date and Startup/Adjustment Amount. Now when you run the 4-1-5-61 1099 Payment Journal, that vendor information will be accurate.
