What is mobile shop billing software?
Mobile shop billing software is the tool that turns a sale into a proper invoice — with the right tax treatment, the customer's details, and the specific handset or accessory being sold — and keeps that invoice on record afterwards.
In Phoneo a bill is not a standalone document. Selling a handset by IMEI marks that unit as sold in your inventory and records the amount against the customer in the same action, so one entry keeps billing, stock and the customer's account in step.
Who is it for?
- Shops billing walk-in customers for phones and accessories
- Shops that also need GST invoices for registered buyers
- Owners who currently write bills by hand and keep carbon copies
- Shops that share bills with customers over WhatsApp
The problem it solves
Handwritten bills give you no searchable record. When a customer returns three months later with a warranty question, finding the original bill means going through a stack of books.
Keeping billing separate from stock means entering the same sale twice — once on the bill, once in the register — and living with the gap between the two.
What's included

Non-GST billing
Issue non-GST bills where a tax invoice is not required, from the same system.

Features in detail
GST and non-GST invoices
A mobile shop serves two kinds of buyer in the same day. A walk-in customer wants a simple bill; a registered business wants a tax invoice it can claim against. Phoneo handles both, applying GST from your settings when the invoice calls for it.
Because the GST treatment comes from your configuration rather than being typed each time, the arithmetic on the bill is consistent — which is what makes the records usable at filing time.
Sales invoices for phones and accessories
You can bill a single handset, a single accessory, or a mixed sale where a phone goes out with a case and a charger. New phones, second-hand phones and accessories all bill from the same stock, so the invoice and the inventory never disagree about what left the shop.
Purchase invoices
Purchases are recorded the same way sales are, so what you bought from a supplier sits in the system next to what you sold. That is what lets your accounts show both sides of the business rather than only the money coming in.
Invoice history and invoice records
Every invoice you raise stays on record and can be found later. When a customer comes back about a warranty, a return or a payment, the original bill is a lookup rather than a search through paper — and because Phoneo is cloud-based, it is available from whichever device you have with you.
WhatsApp invoice sharing
The bill can go straight to the customer on WhatsApp as soon as the sale is complete, or be printed at the counter. Sending it digitally means the customer keeps a copy that does not fade, tear or get lost — which removes most of the disputes that start with a missing bill.
Customising your invoice
Invoice settings let you set how your bill presents itself — shop name, logo and the details you want on the document. It is the difference between a bill that looks like a receipt and one that looks like it came from an established business.
Invoices for previous dates
Sometimes a sale gets recorded after the day it happened. Phoneo lets you create an invoice for a previous date so the record matches when the transaction actually took place rather than when you got round to entering it.
How is it different from registers, Excel or WhatsApp?
| Job to be done | Handwritten bill book | Phoneo |
|---|---|---|
| Find a bill from three months ago | Search the stack | Look it up |
| Give the customer a copy | Carbon copy | WhatsApp or print |
| Keep stock in step with the sale | Separate entry | Same entry |
| Switch between GST and non-GST | Different book | Same screen |
| Know what a customer still owes | Add it up by hand | On their account |
