Custom Inventory Management Software for Stock You Can Trust

We build custom inventory management software for distributors, wholesalers, manufacturers and retailers who have outgrown spreadsheets and the stock module inside their billing tool. The goal is simple: the number on screen should match what is on the shelf, in every godown and branch, without a weekend stock count to find out.

Most stock problems come from gaps between steps: goods received but not entered, transfers sent but not acknowledged, batches mixed up, or returns lying in a corner. We design the receiving, picking, transfer and audit steps so that each one leaves a record, ideally with a barcode scan rather than typing.

The software connects to the tools you already use, such as your billing system, Tally or an online store, so each receipt, sale and transfer is entered once and flows everywhere it is needed. Reports show stock value, slow movers and ageing, so you can free up cash tied up in inventory.

Who it's for

Who Inventory Software is for

Distributors and stockists

FMCG, pharma, electrical and hardware distributors who serve many retailers, handle schemes and returns, and need accurate stock by batch before salesmen take orders. That is what inventory software for distributors has to get right first.

Wholesalers and traders

Businesses with large SKU counts across godowns, where finding an item, counting it and moving it between locations takes too much staff time today. A wholesale inventory management system built around your godowns and SKU codes fixes that.

Manufacturers

Units that need raw material, work-in-progress and finished-goods stock kept separately, with material issued to production and consumption tracked against output.

Multi-branch retailers and online sellers

Retail chains and D2C brands selling in stores and online, who need one stock pool, transfers between branches and fewer oversold orders, often alongside the retail management software they already run.

What you get

Features we build

Multi-location and bin-level stock

Multi-location inventory management down to the shelf: track stock by warehouse, branch, rack and bin. See where each item sits, how much is reserved for open orders, and what is actually free to sell at any location.

Purchase orders and GRN

Raise purchase orders, receive goods against them with a goods receipt note, record short or damaged quantities, and keep supplier-wise pending deliveries visible to purchase staff.

Batch, serial and expiry tracking

Record batch numbers, manufacture and expiry dates or serial numbers at receipt. Picking follows first-expiry-first-out where needed, and near-expiry stock is flagged before it becomes a write-off.

Barcode and QR labelling

Print barcode or QR labels for items, cartons and bins, and use handheld scanners or phone cameras for receiving, picking, dispatch and transfers to cut typing errors.

Reorder levels and purchase suggestions

Set minimum and reorder levels per item and location, or let the system suggest them from recent consumption. Buyers get a daily list of what to order and from whom.

Stock transfers between locations

Send stock from one godown or branch to another with a transfer note. Goods stay in transit until the receiving location confirms, so missing quantities are caught immediately.

Mobile stock audit and cycle counts

Run full or cycle counts from an Android phone by scanning bins and items. Cycle counting inventory by zone or by fast movers means you rarely need to shut the godown for a full count. Variances are listed for review and adjusted only after approval, with a record of who counted what.

Integrations with billing, Tally and e-commerce

Sync sales and purchases with your POS or billing software, post vouchers to Tally, and push available stock to Shopify, WooCommerce or marketplace listings through their APIs where available.

FAQ

Frequently asked questions

How much does custom inventory management software cost?

A single-location stock system typically costs ₹60,000–1.75 lakh. Multi-location inventory with batches, transfers, a mobile audit app and one integration is usually ₹1.75–4.75 lakh. A full warehouse management system with bin locations and several integrations can run ₹4.75–12 lakh. The inventory management software price depends mostly on the number of locations, devices and integrations, and we give a fixed quote after understanding your stock flow.

Why build custom inventory software instead of using my billing software?

Billing tools handle basic stock well. They start to struggle with multiple godowns, transfers in transit, batch-wise picking, bin locations and mobile counting. If your current software already covers what you need, keep it. If staff are keeping side registers to fill the gaps, a custom inventory management system is usually worth considering.

Is there affordable inventory management software for startups?

Yes. Inventory management software for startups and small traders usually begins as our single-location system: items, purchases, stock, reorder levels and barcode support, with no per-user fees. If a ready-made subscription tool already covers your needs, it may cost less for now, and we will tell you so honestly.

Do you sell a ready-made inventory product?

No. We are not an inventory management software company selling one fixed package. We build custom software for your stock flow, so you pay once for what you use, own the source code, and can add locations or integrations later without a licence upgrade.

Can it integrate with Tally?

Yes. We commonly post purchase, sales and stock journal vouchers to Tally so your accounts stay in sync. The exact method depends on your Tally version and setup, and we confirm it during scoping. Items and ledgers are mapped once, and failed postings are listed for review rather than silently skipped.

Do we need special barcode hardware?

Not necessarily. Android phones can scan barcodes and QR codes with the camera, which is fine for small teams. For high-volume receiving and picking, rugged handheld scanners are faster. We help you choose, and labels can be printed on standard thermal label printers.

Can it sync stock with my online store?

Yes, for platforms with usable APIs such as Shopify and WooCommerce, and for marketplaces where seller APIs are available to you. Available stock is pushed at regular intervals and orders are pulled back, reducing overselling across channels. You can hold back a safety buffer per channel so a store sale does not leave an online order unfulfilled.

Does it work for businesses outside India?

Yes. The software is not tied to GST and can use VAT or sales tax, local currencies and units. Distributors and retailers in the US, UK, Australia and Canada can work with us remotely, with calls scheduled to overlap their business hours.

Will it work in godowns with weak internet?

The mobile app can store scans offline and sync when a connection is available, which helps in large godowns with poor coverage. We decide with you which actions must be online, such as stock reservations for orders, and which can safely queue until the device reconnects, so staff are never stuck waiting for a signal.

Any inventory management tips before we start?

A few habits help more than any software: enter goods received the same day, label every rack and bin, count fast-moving items every week or two instead of relying on a yearly full count, and set reorder levels from real consumption rather than guesswork. Good software makes these habits easy; it cannot replace them.
