How to keep a customer credit ledger in Excel

Every entry in a credit ledger (veresiye, selling to customers on a tab) must have five pieces of information: date, customer name and phone number, item purchased, amount and the promised payment date. When these five fields are filled in, collections speed up and disputes go away. A paper notebook gets lost and can't see the total; Excel or a mobile app shows your total receivables instantly.

The five fields the ledger needs

Date: when it was given. Name and phone: so you can send reminders. Item/description: the answer to "what did they buy?" — the most useful field in a dispute. Amount: the exact figure. Promised date: the starting point for follow-up.

A credit entry without a phone number is, more often than not, an entry you never collect.

Habits that speed up collections

A short reminder message the day before the due date noticeably raises the collection rate. Calling within the first 3 days after the payment date passes is far more effective than waiting two weeks.

Accept partial payments and record every payment in the ledger right away; customers keep paying as they see their debt going down.

Setting a limit

Set an upper limit for each customer (for example 2.000 ₺) and don't extend new credit once the limit is reached. A ledger without limits leaves your working capital out on the street within a few months.

Don't give a new customer a large amount of credit the first time; start small and see how they pay.

Moving from a paper notebook to digital

A paper notebook has three problems: it gets lost, it can't see the total, and it doesn't remind you of late payments. Excel solves all three; if you put the file in your cloud account, you can check it from your phone too.

If you need fast entry at the counter, a mobile credit-ledger app is more convenient: picking a customer and typing the amount takes a few seconds, and the app sends the reminder.

The legal side

A credit ledger is a private record in which you track your own receivables; it does not replace official books. You still need to document your sales with a receipt or invoice. For large amounts, getting a promissory note or a written acknowledgment of debt strengthens your hand if collection becomes a problem.

Frequently asked questions

Should I sell on credit?

For neighborhood shopkeepers, credit often means customer loyalty. The way to manage the risk isn't to refuse; it's to set limits, keep clean records and follow the due dates.

What can I do about a customer who doesn't pay?

First try a written reminder and an offer of partial payment. If that gets no result and the amount is high, you will need legal advice about enforcement proceedings; that's why detailed records matter.

Is it safe to keep the ledger on a phone?

A file kept in your cloud account is safer than a paper notebook that can get lost. Make sure two-step verification is turned on for your account.
