Stock and cash cycles: a record-keeping guide for Nigerian small businesses

Stock bought, stock sold and money collected are separate events

A Nigerian trading business may pay for stock today, receive it later, sell on credit and collect cash after that. A sales record can show activity while the bank balance remains low. Keep the physical stock movement and the money movement connected without assuming they happen on the same date.

Start with a simple batch or item record showing purchase evidence, quantity ordered, quantity accepted and the costs you are tracking. Record sales and customer payments separately. This is an operational worksheet, not a replacement for your accountant's reporting system or tax records.

Reconcile quantity before valuing a batch

Illustration only: you accept 200 units, sell 130 and write off 5 damaged units. Expected remaining stock is 65 units. If a physical count finds 62, investigate the difference of 3 rather than automatically recording it as a sale. Possible causes include an entry error, a return, damage or a missing movement record.

Give each adjustment a reason and supporting evidence. Distinguish customer returns that are resalable from damaged items. If several batches share the same product name, keep enough batch or purchase information to explain the quantities and costs in your records.

Track promised and actual payment dates

For each credit sale, record the invoice amount, agreed due date, payments received and outstanding balance. A promised payment is not cleared funds. Reconcile receipts to the relevant sale before treating a general bank deposit as settlement of a particular invoice.

Illustration only: invoices total ₦500,000 and confirmed receipts total ₦350,000 against them. The recorded outstanding amount is ₦150,000 before any documented credit note or dispute. That arithmetic does not establish that the balance will be recovered or that every receipt has been correctly allocated.

• Purchase and accepted-stock records
• Sales quantities and invoice evidence
• Returns, damage and stock adjustments
• Agreed payment dates and actual receipts
• Outstanding balances and disputes
• Physical counts and reconciled differences

Build a cash timeline using confirmed commitments

List supplier payments, delivery charges and other known commitments by due date. Keep expected customer receipts beside them but clearly labelled as expected. If a planned receipt is delayed, the business still needs to consider the confirmed payment commitment rather than counting the same money twice.

A timeline can reveal which assumptions deserve attention: delivery date, usable quantity, sell-through or collection timing. It is not an affordability assessment or an instruction to borrow. Ask the appropriate professional about financing or accounting questions that arise from the actual records.

Keep inventory measurement separate from this worksheet

IAS 2's inventory principles involve more than multiplying planned stock by a future selling price. Obtain the accounting treatment appropriate to your business. This guide's examples only explain movement and reconciliation; they do not establish a complete stock valuation or reported profit.

For foreign-currency purchases, retain the original invoice and the dated conversion or payment evidence used in your records. The converter helps you inspect a quote but does not reconcile your bank, manage receivables or maintain accounting records. Keep those functions in your own authorised business system.
