Running a small business means a hundred small jobs every day: keeping the register, replying to customers, chasing udhaar, counting stock, checking how the month is going. Those jobs eat the time you should be spending on the business itself.
This book shows you how to hand much of that work to ChatGPT, right from your phone. Every page takes one real problem and gives you a ready prompt to copy and fill in, a worked example, and a simple check so you know the answer is right before you use it.
You don't need to be good with computers. If you can send a WhatsApp message, you can do everything in this book, and almost all of it works on the free version of ChatGPT.
Four ready-made Excel templates come with the book: a Cashbook, a Sales Tracker, a Stock and Orders sheet, and a Customer Credit (udhaar) list. Prefer paper? Printable versions are at the back.
