How to keep track of customer dues (udhar) without a notebook

Every credit sale in NegoBill becomes the customer's due; every payment settles the oldest bills first; the statement is one tap on WhatsApp. No notebook, no arguments.

Updated 26 Sept 2026 · Applies to NegoBill V5

The problem

A shop that gives credit ends up with a notebook nobody trusts: pages of names, amounts crossed out, a customer who says they paid, a total nobody knows.

What NegoBill does

  1. A sale to a named customer that is not paid on the spot is a credit sale. The bill exists, the due exists, nothing more to write.
  2. When they pay, you record Received cash (or UPI, or card) against the bill or against the customer. The oldest bills close first.
  3. The statement shows bills, payments and the running balance in plain words, and goes to them on WhatsApp.
  4. The dashboard shows what all customers owe you, and the contact list sorts by it.

Why it stays right

Every sale and payment posts to a ledger you never edit. A mistaken payment is voided, not erased, and the due comes back exactly. The books cannot drift from the bills.

Questions people ask

What if a customer already owed me before I started?

Enter it as an opening balance; it is a due like any bill and the first payment settles it first.

Can a customer pay part of a bill?

Yes. Any amount, against one bill or against the account; the rest stays due on that bill.

Can I see everyone who owes me, most first?

Yes. The contact list sorts by what they owe you, and the dashboard shows the total.
