Customer credit
A customer balance is the unpaid part of a real sale.
It may come from a customer buying now and paying later, paying only part of the amount, leaving a deposit before work starts or completing payment on another day.
The balance only stays useful when it remains attached to the sale that created it. “Customer owes ₦10,000” is weaker than a record that still shows what was sold, the full price, what was paid and when.
What to record
A balance should explain itself without depending on memory.
- Customer name or clear identifier
- Transaction date
- Product, service or job
- Full amount of the sale
- Amount already paid
- Cash, transfer or split payment
- Balance remaining
- Receipt, reference or useful follow-up note
Simple example
Write the full transaction, not only the amount still owing.
| Customer | Sale | Total | Paid | Method | Balance |
|---|---|---|---|---|---|
| Amaka | Printing job | ₦45,000 | ₦20,000 | Transfer | ₦25,000 |
A note such as “Balance on pickup” keeps the agreement beside the numbers instead of inside someone's memory.
Part payments
Every later payment should return to the balance it is settling.
If the original balance is ₦10,000 and the customer later pays ₦6,000, record that payment against the original outstanding sale and reduce the balance to ₦4,000.
Do not treat the ₦6,000 collection as another sale. The sale already happened. The later money is settlement of an earlier receivable.
- Original sale amount
- Original balance
- New payment amount
- Payment method
- Payment date
- New remaining balance
Deposits and credit
Advance payments and zero-payment credit sales follow the same rule.
A deposit should stay connected to the job it belongs to. A fully unpaid credit sale should still record the customer, what left the business, the full amount and the balance even when no money was received immediately.
The useful principle is simple: every amount still owing should have a traceable origin.
Review routine
Review balances before they become old stories.
Businesses that sell on credit often should review outstanding balances frequently and immediately after any customer payment.
- Who is still owing?
- How much remains for each customer?
- Which balances are oldest?
- Which customers paid something recently?
- Which sales are now fully settled?
- Which follow-up needs to happen next?
Choose a method
Paper, WhatsApp and a dedicated balance record each behave differently.
Paper is familiar but can be difficult to search and update. WhatsApp can preserve a conversation, but balances become scattered across chats and may not match the business's actual sales record.
A dedicated record system is most useful when it keeps the original transaction, payment history and current balance together. Berlvis Books does this with customer-linked sales and later-payment allocation.
