Optical billing software no longer has to be installed on one computer. Web-based software runs in a browser, so the same shop can bill from a desktop at the counter, a laptop at home or a tablet on the floor, with the data in one place.

What you need

A desktop, laptop or tablet with an up-to-date browser such as Chrome or Edge.
A steady internet connection (broadband or a mobile hotspot as backup).
A thermal printer for paper bills.
An optical billing web app with eye power fields and stock.

Why browser-based software suits small shops

Nothing to install or update. New features arrive automatically.
Data isn't tied to one machine. If a computer breaks, log in from another one.
Check the shop from anywhere. See today's sales from home in the evening.
Use what you have. An existing desktop or laptop is usually enough.

What a good optical billing web app should do

Find a customer by mobile number and show their past purchases and prescriptions.
Let you enter SPH, CYL, AXIS and PD on the bill itself.
Search stock while billing and reduce it automatically.
Record cash, UPI or card, plus advance and balance.
Print bills or share them as a PDF.
Keep your data backed up on secure servers.
Work in the language your staff are comfortable with.

Security habits

Log out on shared computers, and don't save the password in a browser others use.
Keep the browser and operating system updated.
Don't keep customer prescriptions in personal chats or photo galleries.

Opticdigit runs in the browser at app.opticdigit.com on a desktop, laptop or tablet, and you sign in with your mobile number and a one-time SMS code. There is also an Android app for billing and Bluetooth printing from a phone or tablet you already own.
