Guide to Stock Movements, Financial Ledger Entries, and Item Adjustments in Accounting Systems

In any business that deals with physical goods, managing stock levels and reflecting accurate financial records is crucial. This guide explains how transactions like customer invoices, supplier invoices, receipts, payments, and item adjustments affect stock, how to allocate payments and receipts to reduce outstanding balances, and the appropriate ledger entries.

Customer Invoices and Stock Reduction

Stock Impact:
A customer invoice is created when goods or services are sold to a customer. When goods are sold, stock decreases as items leave the business.

Example Transaction:
Goods Sold: 10 units of Product A.
Stock Before Sale: 100 units.
Stock After Sale: 90 units.

Journal Entries for Customer Invoice:
Account Debit Credit
Accounts Receivable (Customer) $500
Sales Revenue $500
Cost of Goods Sold (COGS) $300
Inventory (Stock) $300

  • Accounts Receivable: Increases because the customer owes money.
  • Sales Revenue: Recognizes income from the sale.
  • COGS: Reflects the cost of the goods sold.
  • Inventory: Decreases due to stock reduction.

Supplier Invoices and Stock Increase

Stock Impact:
A supplier invoice is created when goods are purchased from a supplier. Stock increases because new inventory is added to the business.

Example Transaction:
Goods Purchased: 20 units of Product B.
Stock Before Sale: 50 units.
Stock After Sale: 70 units.

Journal Entries for Customer Invoice:
Account Debit Credit
Inventory (Stock) $400
Accounts Payable (Supplier) $400

  • Inventory: Increases as new stock is added.
  • Accounts Payable: Reflects the liability to the supplier for the purchase.

Receipts and Payments for Reducing Outstanding Balances

Receipts:
A receipt is recorded when a customer makes a payment toward an outstanding invoice. This reduces the total outstanding debt in Accounts Receivable.

Journal Entries for Receipts:
Account Debit Credit
Bank (Cash/Bank Account) $500
Accounts Receivable (Customer) $500

  • Bank: Increases as the business receives cash.
  • Accounts Receivable: Decreases because the customer’s outstanding balance has been reduced.

Payments:
A payment to a supplier decreases the Accounts Payable balance, representing the settlement of liabilities.

Journal Entries for Receipts:
Account Debit Credit
Accounts Payable (Supplier) $400
Bank (Cash/Bank Account) $400

  • Accounts Payable: Decreases as the amount owed to the supplier is reduced.
  • Bank: Decreases to reflect the cash outflow.
Allocating Receipts and Payments:
It is critical to allocate receipts (from customers) and payments (to suppliers) to specific invoices, reducing outstanding balances. This keeps Accounts Receivable and Accounts Payable accurate.

Item Adjustments and Stock Management

Stock Impact:
Item adjustments occur when stock levels are corrected due to damage, expiration, loss, or overstock situations. Adjustments can increase or decrease stock, depending on whether you are adding or removing items from inventory.

Stock Increase: Happens when missing items are found, or unaccounted stock is added back.
Stock Decrease: Occurs when goods are damaged, expired, or lost.

Example Transaction:
Stock Decrease: 5 units of Product C are damaged. Stock Before Adjustment: 50 units. Stock After Adjustment: 45 units.

Journal Entries for Stock Adjustments:
Adjustment Type Account Debit Credit
Stock Increase Inventory (Stock) $300
Inventory Adjustment (Gain) $300
Stock Decrease Inventory Adjustment (Loss) $150
Inventory (Stock) $150

Stock Increase:
  • Inventory: Increases as more stock is added to the system.
  • Inventory Adjustment (Gain): Recognizes the benefit of additional stock.
Stock Decrease:
  • Inventory Adjustment (Loss): Reflects the loss of stock.
  • Inventory: Decreases as stock is reduced.

Examples of Ledger Impact for Transactions

Here’s how different transactions would impact stock and the general ledger:

Example 1: Customer Sale

A business sells 15 units of Product X for $1,000.

Account Debit Credit
Accounts Receivable (Customer) $1,000
Sales Revenue $1,000
Cost of Goods Sold $600
Inventory (Stock) $600

  • Stock decreases by 15 units.
  • Financial impact on Sales Revenue and COGS.

Example 2: Supplier Purchase

A business buys 30 units of Product Y from a supplier for $750.

Account Debit Credit
Inventory (Stock) $750
Accounts Payable (Supplier) $750

  • Stock increases by 30 units.
  • Financial impact on Inventory and Accounts Payable.

Example 3: Stock Adjustment (Decrease due to Loss)

10 units of Product Z are lost, with a value of $200.
Account Debit Credit
Inventory Adjustment (Loss) $200
Inventory (Stock) $200

  • Stock decreases by 10 units.
  • Financial impact on Inventory Adjustment (Loss).


Example 4: Customer Receipt

A customer makes a payment of $500.
Account Debit Credit
Bank (Cash/Bank Account) $500
Accounts Receivable (Customer) $500

  • Accounts Receivable decreases as the customer pays off part of the outstanding balance.
  • Bank increases with the incoming cash.

  • Receipts and Payments adjust the balances in Accounts Receivable and Accounts Payable.
