Make a journal entry

8 min · Intermediate

A journal entry moves amounts between accounts directly, with debits on one side and credits on the other. You need one for things no other form covers: depreciation, accruals, corrections and entries your accountant gives you.

In this lesson you will

  • Post a balanced journal entry
  • Know what the Adjusting entry box is for
  • Know when another form is a better choice
Make General Journal Entry with depreciation of 100.00 debited and credited

Enter the journal entry

Bright Ideas Studio records a month of depreciation on its furniture and equipment: an expense of $100.00, and the same amount added to Accumulated Depreciation.

Step 1: Open Activities → Make Journal Entry

The form opens as Make General Journal Entry. Enter the date, an entry number if you number them, and a memo that explains the entry to anyone reading it later. Then fill in one line per account.

  1. Date of the entry.
  2. Debit on the first line: Depreciation Expense, 100.00.
  3. Credit on the second line: Accumulated Depreciation, 100.00.
  4. Difference must be $0.00. The form shows In balance when debits equal credits.
  5. Save & Post posts the entry.
Journal entry with Depreciation Expense debit 100.00, Accumulated Depreciation credit 100.00, in balance
Tip: Not sure which side is which? Expenses and assets go up with a debit; income, liabilities and equity go up with a credit. See debits and credits.

Step 2: Adjusting entries and classes

Tick Adjusting entry for year-end or period-end adjustments, such as the ones your accountant sends. They are listed on the Adjusting Entries and Adjusted Trial Balance reports, so the adjustments are easy to review. Class (optional) tags the entry for reports by class.

When not to use a journal entry

Step 3: Use the form made for the job

Customer invoices and payments, vendor bills, bill payments, paychecks and sales tax payments have their own forms. Those forms update customer and vendor balances, aging reports and tax reports; a journal entry to Accounts Receivable or Accounts Payable doesn't apply to any invoice or bill. To change a journal entry you posted, find it in Activities → Transactions.

Careful: AcboBooks won't post an entry that is out of balance. If the Save & Post button stays grey, check the Difference.
