Journal Posting in Accounting: Transfer Lines and Check Completeness
Journal posting in accounting transfers already-recorded journal lines into the relevant account ledgers. The job is to preserve the account, side, amount and reference. It is different from deciding which accounts an event should affect. Use a completion check as well as an arithmetic check.
Start with approved inputs
In this fictional model, opening balances are Cash debit 2,800, Supplies debit 900, Equipment debit 1,200, Accounts payable credit 1,100 and Owner capital credit 3,800. Opening debits and credits are both 4,900. Two journal entries have already been supplied and approved for this exercise.
The account set is complete for the stated model. There are no taxes or omitted opening accounts. OpenStax describes posting as moving journal information into the ledger; we focus on that transfer rather than re-analyzing the source events.
Post each supplied line once
Copy every line to its named account and side. Use J-61 or J-62 in the ledger, and mark the destination account against each journal line.
Original supplied journal and expected balances
J-61: Debit Accounts payable 500; credit Cash 500.
J-62: Debit Cash 1,100; credit Service revenue 1,100.
Expected closings: Cash debit 3,400; Supplies debit 900; Equipment debit 1,200; Accounts payable credit 600; Owner capital credit 3,800; Service revenue credit 1,100.
Closing trial balance: debits 5,500; credits 5,500.
Inspect the actual account-card rows
All dates below are fictional April dates in the same teaching period. Journal J-61 is dated April 3 and points to the payable and cash cards; J-62 is dated April 5 and points to the cash and revenue cards. Each card carries the journal reference back to those lines.
Original posted account cards
Cash: April 1 opening debit 2,800; April 3 J-61 credit 500, running debit balance 2,300; April 5 J-62 debit 1,100, closing debit balance 3,400.
Accounts payable: April 1 opening credit 1,100; April 3 J-61 debit 500, closing credit balance 600.
Service revenue: April 1 opening zero; April 5 J-62 credit 1,100, closing credit balance 1,100.
Supplies: April 1 opening debit 900; no supplied movements; closing debit 900.
Equipment: April 1 opening debit 1,200; no supplied movements; closing debit 1,200.
Owner capital: April 1 opening credit 3,800; no supplied movements; closing credit 3,800.
Trace an omission and a duplicate
If the 500 debit to Accounts payable is omitted while its cash credit is posted, the reported payable stays at 1,100 rather than 600. Credit balances exceed debit balances by 500. Compare J-61’s two lines with their ledger destinations instead of inventing a balancing entry.
If both lines of J-62 are posted twice, totals may still balance, but cash and revenue are each overstated by 1,100. Matching debit and credit totals does not detect every duplicated complete entry. A once-only reference check addresses a different risk.
Describe the check you performed
The useful answer identifies transfer completeness, not just a balanced number.
Original practice explanation
“I matched all four supplied journal lines to account cards and retained both journal references. The expected trial balance is 5,500 on each side. I also checked that J-62 appeared once, because a complete duplicate could preserve equality while overstating balances.”
Avoid repairing the wrong record
Do not alter an approved journal merely because its posting is missing or duplicated. Identify which record is wrong, propose the correction with its reference and preserve the review trail. An unsupported plug entry hides the original problem.
For another round, ask a partner to remove one posting marker while leaving the balance correct. You should still report incomplete traceability: a matching number is not a substitute for being able to show which journal line produced it.
Questions, answered
Can a duplicate posting leave a trial balance equal?
Yes. Posting both sides twice preserves equality while changing the account balances.
Should I create a new entry to hide an omitted posting?
No. First identify the missing transfer and follow the approved correction process.
