There are two options:

General Ledger:

Use Record Entries in General Ledger if the changes are only for GL account reallocation. Don’t use this option if changes are to reallocate to different job-related items. These include commitments, jobs, cost codes or categories.

Accounts Payable:

Add new distributions to reverse and replace the original distributions. Record a payment for the entries. See the steps below.

Change the distributions on a fully paid invoice in Accounts Payable:
Notes:

• Invoice changes will post to a closed period depending on the accounting date of the invoice
• Change the accounting date of the invoice to the current period if you don’t want to post changes to a prior period
• If you use intercompany accounting, see more information about AP and intercompany before changing prefixes

1. From Tasks, select Change Invoices.
2. Enter the Vendor and Invoice ID for the invoice you want to change.
   • Note: See steps to change the invoice without affecting a closed GL period if needed.
3. Press Tab or Enter until you see the distribution grid.
4. Press Tab or Enter until you move to a new distribution line. Don’t change the original distribution.
5. Enter a new negative line of distribution that offsets the paid line of distribution you want to reverse. Enter the same account and job information as the original paid line of distribution with negative amounts. Enter multiple lines if needed.
6. Enter a new positive line of distribution with correct distribution information. Offsetting negative lines of distribution and new positive lines of distribution will net to zero if correct. The invoice amount doesn’t change.
   • Example: You have an invoice for $100.00 that you entered and fully paid. There are two lines of distribution for $50.00 each. They have incorrect job information. When you correct these invoices, you enter four new lines of distribution. Two lines of distribution for -$50.00 that have the original incorrect job information. Two new lines of distribution for $50.00 each that has the correct job information. The net change to the invoice amount is zero. There are now six distributions instead of two.
7. Click Accept dist after entering each new distribution.
8. Click Accept invoice after making all invoice changes.
   • Note: If you changed the accounting date, specify which date to use for the reversing entries. Select Revised accounting date and click OK.
9. Click Finish and print your journal. Your new distributions net to zero, but they’re unpaid and have a status of Open. Expense information doesn't post to GL until you pay these distributions if you use cash basis accounting.

Pay these distributions to change the status to Fully Paid by printing checks for this vendor or by recording a $0.00 manual check:
Note: If you paid the invoice and the prefix was incorrect, record a new payment. Perform this if you paid with a check or with a credit card. This will create the entries to correct the Credit Card Payables accounts previously used.

1. From Tasks, select Record Manual/Print Quick Checks.
2. Choose a payment method:
   • Quick Check:
     • Check prints with a check stub showing the changes made
     • Check records in Cash Management
     • Can't reuse the Check number
   • Manual Check:
     • Check records in Cash Management
     • Can't reuse the Check number
     • No Check stub prints
   • EFT Payment:
     • Use a Reference number instead of a Check number
     • Reference numbers can include characters like "Inv123412C"
     • No check stub or notice prints
3. Enter Bank information as usual.
4. The payment amount is 0.00.
5. In the Invoice column of the invoice grid, click List. Select the invoice changed above. Change the Amount to 0.00.
   Note: If you fully paid the invoice, clear the Retainage Held on the correcting lines. If you haven't paid retainage, zero the Retainage Held amounts on the credit/negative lines. Enter the total held retainage amount in the Invoice Amount.
6. In the Distribution grid, the Amount column should total 0.00.
7. Click Accept invoice. Click Accept check.
8. Click Finish. Print your journal.
