Five habits that wreck the customer book

Software will not save a book if the habit is wrong. These five are the usual wreck:

1. Two names for one person.
2. Marking a payment as if it were another sale.
3. A number with no currency.
4. Sending the whole spreadsheet on WhatsApp.
5. Waiting a week to write the sale down.

Fix the habit first. Kaymn is the customer book, not a till and not kaymn.com. Seven days free.
