Inventory management software: the basics

Inventory software keeps a running count of every item you hold, where it is, what it cost and how fast it moves. Done well, it tells you what to reorder, what is stuck, and whether the stock in the books is the stock on the shelf.

Start with a clean item master

Everything else depends on the item list. A messy master, with "Fevicol 1kg", "FEVICOL 1 KG" and "Fevicol-1kg" as three items, makes every report wrong. Before buying or switching software, fix the master:

One item, one name. Decide a naming pattern, such as Brand + Product + Size + Colour, and stick to it.
Group items by how you analyse them: brand, product type, or both.
HSN code and GST rate on every item, checked once by your accountant.
Units that match how you buy and sell (see below).
Remove dead items that have had no movement and no stock for over a year, or mark them inactive.

Units, alternate units and packs

A tile dealer buys in boxes and sells in boxes or square feet. A hardware wholesaler buys screws in cartons of 50 packets and sells packets. Inventory software must convert between these without manual maths, otherwise stock goes wrong every time a carton is opened. Define the base unit (the smallest unit you sell) and the conversion for each item. The guide on alternate units in Tally shows how this works in practice.

Locations: godowns, shops and vans

If stock sits in more than one place, track it by location. A distributor with a main godown, a counter and two delivery vans has four locations. Transfers between them are recorded as movements, not as sales and purchases, so total stock does not change but each location's balance does. Without this, the counter keeps saying "it's in the godown" and the godown says "we sent it to the counter". See godowns and multi-location stock.

Batches, expiry and serial numbers

Not every business needs these, but those who do need them badly:

Batches and expiry: pharma, food, agri-inputs, paints and adhesives with shelf life. You need to sell oldest first and see what expires in the next 60 days.
Serial numbers: electronics, appliances, mobiles, solar inverters, where warranty is tied to a specific unit.
Per-piece barcodes: when each piece is unique or must be traced, such as jewellery or high-value appliances.

If your trade does not need them, do not switch them on. Every extra field slows down billing.

Valuation and why it matters at year end

Closing stock value goes straight into your profit. If you hold ₹42 lakh of stock and it is valued wrongly by 5%, profit is off by ₹2.1 lakh. Software values stock by a method such as weighted average or FIFO; agree the method with your CA and do not change it casually. Physical counts at least once a year, and for fast-moving items more often, keep the book figure honest. The stock audit checklist explains how to run a count.

Reports that actually get used

Report	Use it to
Stock summary by group	See total holding by brand or category
Item movement	Check inward, outward and closing for one item over a period
Fast and slow movers	Decide what to reorder and what to push or discount
Items below reorder level	Prepare purchase orders
Ageing of stock	Find stock lying unsold for 90, 180, 365 days
Location-wise stock	Plan transfers between godowns and counters

Checklist when choosing inventory software

Does stock update the moment a bill or delivery is made, or only later?
Can it handle your units, locations and, if needed, batches or serials?
Do sales staff see available stock before promising delivery?
Is inventory part of the accounting system, or separate? Separate means reconciliation work every month.
Can you print barcodes and labels from the same item master?

Stock visibility with Tally and Cashflow OS

If you keep inventory in TallyPrime, Cashflow OS shows stock and item summaries from the synced data on the phone and web, so salespeople and the owner can check before promising. Items can carry photos, display names, brands and custom fields, using Tally stock groups as categories. Barcodes and labels can be printed per item or per piece and scanned with a phone camera, and stock journals can be posted to Tally once writing is switched on. See barcodes and labels.

Avoid these

Common mistakes

MistakeThe same item entered under three spellings
Do this instead
Pick a naming pattern such as Brand + Product + Size + Colour, merge duplicates, and stick to it.
MistakeBuying in cartons and selling in pieces with no conversion
Do this instead
Set the base unit and the conversion on each item, so stock stays right when a carton is opened.
MistakeRecording godown transfers as sales and purchases
Do this instead
Record them as stock movements between locations, so total stock is unchanged and each location's balance is right.
MistakeSwitching on batches and serials for every item
Do this instead
Use them only for items with expiry or warranty tracking; elsewhere they slow billing without benefit.

Keep handy

In Cashflow OS

How Cashflow OS helps

Cashflow OS puts your TallyPrime books on every phone in the team. Where it fits this topic:

Stock on the phone before you promise

Stock and item summaries sync from TallyPrime, so salespeople and the owner can check quantities on phone or web, with item photos and your own display names.

See Item photos and display names

Barcodes and labels from the same items

Print labels per item or per piece on thermal or A4 printers and scan with the phone camera; stock journals can be posted to Tally once writing back is on.

Questions people ask

Should inventory be separate from accounting software?

Keeping them together avoids a monthly reconciliation and makes closing stock in the books match the stock records. Separate systems only make sense when the inventory side needs features the accounting software cannot offer.

How often should I count stock?

At least once a year for the whole stock, and a rolling count of your top-value or fast-moving items every month. Differences found early are easier to explain.

What is a reorder level?

The quantity at which you should place a new purchase order so stock arrives before you run out. It depends on daily sales and supplier lead time.

Do I need batch tracking?

Only if your items have expiry dates or batch-specific quality, or if regulations require it. Otherwise it adds work without benefit.

What is the difference between FIFO and weighted average?

FIFO assumes the oldest stock is sold first, so closing stock is valued at the latest purchase costs. Weighted average uses the average cost of all units held. Agree the method with your CA.

How do I handle stock in a delivery van?

Treat the van as a location: transfer stock to it, bill sales from it, and count it at the end of the day or week.

How do I start if my current stock figures are wrong?

Do a physical count, enter it as opening stock on a fixed date, and record every movement from then on. Do not carry old errors forward.

What is the difference between stock ageing and item movement?

Item movement shows inward, outward and closing for one item over a period. Ageing shows how long current stock has been lying, such as over 90 or 180 days.
