A fictional bookkeeping close packet with source documents, journal entries, ledgers, bank reconciliation, financial summaries and a short cash forecast. Assemble and revise the six lesson outputs into one clearly labeled fictional practice packet.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Register all eight source documents with linked payments and unpaid balances.
  • Provide the chart of accounts, journal, ledgers and initial trial balance.
  • Reconcile bank and book cash with supported adjusting entries.
  • Separate simplified profit from cash and build the two-week forecast.
  • Assemble a balanced final position summary and a clear limitations note.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Accuracy: amounts, classifications and decisions agree with the supplied evidence and stated assumptions.
  • Reasoning: each important choice names the rule, observation or comparison that supports it.
  • Responsible scope: the packet protects information, respects authority limits and routes unresolved concerns appropriately.
  • Usability: a new reader can follow the ordered lesson outputs, identify ownership and see what is complete or still uncertain.

The idea in everyday life

Bank and bookkeeping balances can differ even when both contain valid transactions. Deposits and payments may clear at different times, and a bank may record fees or interest before the bookkeeper receives the statement. Reconciliation explains the difference. The exercise supplies all statement facts and uses no banking login or real account information.

The idea

Bring two records to the same cutoff; only book-side omissions change the books.

Try it

One step at a time.

Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.

  1. 1

    Create separate bank and book reconciliation columns with the same month-end cutoff. Start from the supplied $1,040 statement balance and $1,000 ledger balance without changing either original record.

  2. 2

    On the bank side, add the deposit that is in the books but not yet on the statement. Subtract the supplier payment that is recorded but has not cleared the bank. Link both to their earlier documents so neither is recorded twice.

  3. 3

    Add interest and subtract the fee on the book side. Prepare two balanced journal entries with supporting statement references, then update Cash and the new income and expense accounts.

  4. 4

    Check that both adjusted balances equal $1,010. If they did not agree, preserve the unresolved difference and investigate; never invent income, expense or a cash entry solely to force agreement.

Example

See how it works.

Fictional practice: Oak’s book Cash is $1,000. Its statement shows $1,040. Of the earlier $150 cash service receipt, $20 was deposited too late to appear on the statement; that deposit is already in the books. D8’s $50 supplier payment has not cleared the bank. Bank-adjusted cash is $1,040 + $20 − $50 = $1,010. The statement also shows $15 interest earned and a $5 bank fee, neither in the books. Book-adjusted cash is $1,000 + $15 − $5 = $1,010. Record debit Cash/credit Interest Income $15 and debit Bank Fee Expense/credit Cash $5; do not record the timing items again.

Check your work

Did you cover these?

  • Both adjusted balances equal $1,010.
  • Only interest and the fee create new book entries.
  • Timing items link to previously recorded transactions.
Your work

What to finish

A two-sided reconciliation and supported interest/fee adjusting entries.

Common mistake

Watch for this

Posting an outstanding payment or deposit again when it is already recorded in the books.

How can I tell I understand it?

You can demonstrate all three checks and explain the evidence behind your choices without consulting the worked example.
