Does 399Apps have a mobile app for Android or iPhone?

Billing from a phone: 399Apps vs installed mobile apps

How browser-based mobile access compares with device-installed apps like Vyapar and myBillBook. Prices exclude GST.

Pricing reflects publicly listed plans and is indicative; verify current pricing with each vendor.

What using 399Apps on your phone actually looks like

You open Chrome on Android or Safari on an iPhone, go to 399apps.com, and log in with the same email and password you use on a computer. That is the whole setup — no Play Store search, no app install, no waiting for a download on shop Wi-Fi. Most owners bookmark the login to their phone’s home screen, which every mobile browser supports, so it opens in one tap like any other icon on the screen.

What you see is the same product, not a cut-down companion app. Raising an invoice, checking a party’s outstanding balance, looking up stock in a godown, or pulling a GSTR-1 summary all work from the phone. Because everything is stored in the cloud, a bill you raise on your phone at a customer’s shop is already in the books when your accountant opens them on a desktop ten minutes later.

This also means a lost, stolen or broken phone costs you nothing beyond the phone. Your invoices and ledgers were never sitting only on that handset — you log in from another phone or a PC and carry on from the same place.

Billing at the counter from a phone or tablet

Nidhi POS is built to be used on a phone or tablet at the counter, not just on a desktop. Assign a counter to any staff member on any device: they scan a barcode or pick an item, take payment by Cash, UPI or Card, and print a thermal receipt over Bluetooth. Every sale posts to Nidhi Books for GST and ledgers and deducts stock from the right warehouse in Nidhi Inventory automatically.

Barcode scanning works the way it does on desktop — any USB or Bluetooth scanner that emits keystrokes will pair with the device, and the scan-first billing screen is built for both desktop and mobile. For a small counter, a ₹1,500 Bluetooth scanner plus an existing Android phone replaces a full billing PC setup.

For field use — a salesman visiting retailers, a delivery run, an exhibition stall — the same login on a phone raises the invoice on the spot and shares it over WhatsApp with a UPI payment link, so the customer can pay before the salesman leaves.

Why there is no separate Android app — and why that keeps your price at ₹399

This is a deliberate architecture choice, not a missing feature. 399Apps keeps the cost low by being one cloud product every customer runs, rather than a mobile app maintained across thousands of different phone models, Android versions and offline databases. Maintaining device-installed apps is where a large share of a billing vendor’s engineering cost goes — and it is why per-device and per-user pricing exists in the first place.

The practical effect for you: when a GST rule changes or a bug is fixed, it is live for everyone the next time they load the page. Nobody at your counter is billing on a six-month-old app version they never updated, and there is no "works on my phone but not on the new one" problem when you replace a handset.

It also removes a real cost for shops running old or low-end Android phones, which is a large part of the Indian retail counter. A browser page has no minimum Android version and takes no storage space on the device — the phone you already have is enough.

Who this fits — and who should choose an installed app instead

If you run a shop, godown, clinic or office with normal broadband or mobile data, browser-based access is straightforward and gives you more than an app would: every staff member on their own phone at no extra cost, the same data on the counter PC, and nothing to install or update. If you bill on the move — a distributor’s sales team, a service engineer, a delivery route with 4G coverage — the same login on a phone covers it.

If you genuinely bill in places with no network at all — a van sales route through low-signal areas, a weekly rural market with no data coverage, a basement counter where mobile signal drops — an installed app like Vyapar or myBillBook that queues bills offline and syncs later is honestly the better tool for that specific job. 399Apps needs a connection, and mobile data is usually enough, but "usually" is not "always".

There is a middle path if offline matters but you still want unlimited users and full accounting: 399Apps can be self-hosted on a local PC or LAN server in your premises, where billing keeps working with no internet at all and staff phones connect over your shop Wi-Fi.
