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.

Before you begin

The idea in everyday life

Double-entry bookkeeping records at least two financial effects of a transaction. Debit and credit mean sides of the record, not automatically good and bad or money in and out. Different account types increase on different sides. Understanding the equation makes entries easier to reason through and helps distinguish business performance from owner funding or borrowing.

The idea

Assets equal liabilities plus equity; each entry keeps the equation balanced.

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 a small chart of accounts: Cash, Accounts Receivable, Supplies, Equipment, Accounts Payable, Owner Capital, Service Revenue and Rent Expense. Label each as asset, liability, equity, revenue or expense.

  2. 2

    Beside each account, write whether a debit or credit increases it. Explain how revenue and expenses change profit and therefore equity. Keep money from the owner separate from money earned by the business.

  3. 3

    Apply the equation to D1, D2 and D7 before writing entries. Identify whether each event changes total assets or exchanges one asset for another.

  4. 4

    Write the debit and credit for those three events and check equality. Explain in words why cash is credited in the equipment purchase even though equipment increases, avoiding the mistaken rule that debit always means cash received.

Example

See how it works.

Fictional practice: D1 increases Oak’s Cash asset by $1,000 and Owner Capital equity by $1,000. Record debit Cash, credit Owner Capital. D2 exchanges $200 of Cash for $200 of Equipment, so total assets do not change: debit Equipment, credit Cash. D7 creates $80 of Supplies and $80 of Accounts Payable: debit Supplies, credit Accounts Payable. In this exercise unused supplies are an asset. The working rule is that assets and expenses increase with debits; liabilities, equity and revenue increase with credits. Decreases use the opposite side. Each entry has equal total debits and credits.

Check your work

Did you cover these?

  • Account types are correctly labeled.
  • D2 swaps assets without creating an immediate expense in this exercise.
  • D1, D2 and D7 each have equal debits and credits.
Your work

What to finish

A chart of accounts, entry-direction guide and three balanced transaction analyses.

Common mistake

Watch for this

Calling every cash receipt revenue or every debit a cash increase.

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.
