Inventory Software for Indian Businesses

No two trades count stock the same way. A pharmacy tracks batch and expiry, a mobile shop tracks every IMEI, a garment store tracks size and colour, a distributor tracks godown-wise cases and pieces. 399Apps (Nidhi Inventory) handles all of it — with GST billing built in — for a flat ₹399/month, unlimited users.

Short answer

399Apps (Nidhi Inventory) is cloud inventory and stock management software for Indian businesses, priced at a flat ₹399/month per app with unlimited users. It tracks batch and expiry, serial and IMEI numbers, godown-wise stock with transfers, and size-colour variants — and because GST billing is built into the same system, every sale depletes stock as the invoice is raised.

Before you switch

The three things shop owners ask before putting stock on software

These are the objections that come up again and again when an Indian business moves stock off a register, an Excel sheet or a single-PC package — in small-business forums and in the critical reviews of every inventory app on the market. Honest answers, with the caveats.

"Who is going to enter my 1,200 items in the first place?"

This — not the monthly price — is what actually stops inventory software getting started. The honest version: you export your item and stock list from TallyPrime, Vyapar or Excel and import it with opening quantities and rates, and GSTIN, tax rates and HSN/SAC codes come across so the first invoice is compliant. There is no one-click pull from a Tally file, and if your list only exists on paper you still owe yourself one physical count before you start — no software skips that. Guided onboarding is available for larger datasets.

"The software says 40, the shelf has 37 — then nobody trusts it again"

Stock drift is the complaint that turns up in the critical reviews of every billing app in this market, and it is fair to say no system prevents theft, a miscount at goods-inward or a sale rung up against the wrong item. What 399Apps removes is the most common cause in small shops: a separate billing tool and a separate stock register, so stock only moves when someone remembers to update it. Here inventory and GST billing are one system — the invoice depletes stock as it is raised, so there is no second entry to forget — and minimum-stock alerts tell you which items are worth recounting first, instead of shutting the shop for a full count.

Will non-technical counter staff actually use it? →

"I'll outgrow it the moment I open a second godown"

The usual pattern with cheap inventory apps is that they fit one location and the multi-godown or multi-store tracking sits one tier up — discovered only once the second location is already open. On 399Apps unlimited warehouses, branches, outlets and users are included on every plan from the ₹399/month entry tier, with real-time stock sync and transfers between locations. Prices exclude GST.

Who this fits — and who it doesn't

A good fit

If you run a retail shop, pharmacy, distribution or wholesale business anywhere in India and your stock currently lives in a register, an Excel sheet or a single-PC desktop package, 399Apps fits. You get batch and expiry, serial and IMEI, godown-wise quantities and variant matrices with GST billing in the same system, visible from any device — and the price stays flat at ₹399/month per app as you add staff and locations.

Not a fit

If you need factory-floor manufacturing inventory — bill of materials, multi-stage work-in-progress, machine-wise costing — 399Apps does not cover that today, and TallyPrime with add-ons, Marg ERP or an SAP Business One implementation is the honest recommendation. If your stock work is genuinely one person on one PC with unreliable internet, a desktop package like Busy or Marg ERP is not the wrong answer; look at the self-hosted edition rather than the cloud one.

FAQ

Inventory software in India — FAQ

What is the best inventory software for small business in India? +
The best fit depends on how your trade holds stock — a pharmacy needs batch and expiry, a mobile shop needs serial/IMEI tracking, a garment store needs a size-colour matrix, a wholesaler needs godown-wise stock and unit conversion. 399Apps handles all of these in one system for a flat ₹399/month with unlimited users, cloud or self-hosted.
How much does inventory software cost in India? +
399Apps is a flat ₹399/month per app — the same price across India, with no per-user licence. Most inventory tools charge per seat and stack add-on fees; 399Apps does not.
Does 399Apps inventory come with GST billing? +
Yes. Inventory and billing are one system, so every sale updates stock and produces a GST-correct invoice with GSTR-1 and GSTR-3B-ready data — no double entry and no separate billing tool.
Can I track batch, expiry and serial numbers? +
Yes. 399Apps supports batch-number and expiry tracking with first-expiry-first-out for pharmacies and FMCG, serial/IMEI-level stock for electronics, godown-wise quantities with transfers for distributors, and size-colour matrix stock for garments.
Is 399Apps inventory available on the cloud or self-hosted? +
Both. Run it fully managed on the 399apps cloud with daily backups and an India data region, or self-host on your own server for complete data ownership. The same inventory and billing features work either way.
I have about 1,200 items in my shop and no digital item list — how much work is it actually to get them into 399Apps? +
Be realistic: the typing is the real cost of starting, not the subscription. You export your item and stock list from Tally, Vyapar or Excel and import it, with opening quantities and rates, GSTIN, tax rates and HSN/SAC codes carried across so your first invoice is compliant. There is no one-click pull from a Tally file, and if your list only exists on paper you still owe yourself one physical count before you start — no software can skip that. Guided onboarding is available for larger datasets. Pick a clean cut-over date and run both systems for one filing cycle before retiring the old one.
My software stock and my actual shelf stock never match after a few months — why would 399Apps be any different? +
Drift is usually a process problem, not a software one, and it is honest to say no system prevents theft, a miscount at goods-inward or a sale rung up on the wrong item. What 399Apps removes is the most common cause in small shops: a separate billing tool and a separate stock register, so stock is only updated when someone remembers to. Inventory and GST billing are one system here — every invoice depletes stock as it is raised, so there is no second entry to forget. Minimum-stock alerts then surface the items worth recounting first, rather than shutting the shop for a full count.
I run one shop now but want to open a second outlet next year — will multi-godown stock push me onto a costlier plan? +
No. Unlimited warehouses, branches, outlets and users are included on every 399Apps plan, starting at the ₹399/month entry tier, with real-time stock sync and transfers across locations. This is the common upgrade trap elsewhere: multi-godown or multi-store tracking is frequently held behind a higher-priced tier you only discover you need once the second location is already open. Prices exclude GST.
I run Busy on one office PC and it works fine offline — why would I move stock management to the cloud? +
If a single PC genuinely covers your work and your internet is unreliable, staying put is a fair decision. The cloud earns its place when stock has to be visible from more than that one machine — a second godown, a counter, your phone at a supplier, or your CA at filing time — with no per-PC licence or annual AMC to renew, and nothing to install. If you want cloud-style access without handing your data to someone else to host, the self-hosted edition runs on your own server over LAN.
