Slow Moving Inventory: Find It, Cost It, Book It

Slow moving inventory is stock that still sells, but too slowly for the cash tied up in it. Find it by days since last sale and months of stock left.

By Praveen Nune, Co-Founder & CEO · Updated 9 Oct 2026

A shop owner in a warehouse aisle looks at a few dusty cartons left untouched on a back shelf.

Key takeaways

  1. 01
    Slow moving stock is found with two numbers per item: days since last sale and months of cover. As a starting point (our recommendation), flag "non-moving" at 90 days without a sale and "slow" above six months of cover, then adjust to your lead times.
  2. 02
    Holding ₹10,00,000 of stock for a year costs about ₹1,00,000 in interest at 10% and ₹1,80,000 at 18% (our model, before storage and shrinkage).
  3. 03
    Book a provision (a write-down to net realisable value) while the goods are on your shelves. Destroying, writing off or donating goods can reverse GST credit; selling them, even at scrap value, does not.
  4. 04
    Prevent the next batch at the purchase order, using real lead times and sales rates.

24% of the small and mid-sized businesses in a global survey report that more than 10% of their inventory is dead stock, meaning stock with no realistic buyer, up from 12% in 2024 (Netstock 2026 Benchmark Report, 150+ respondents).

Dead stock starts as slow stock that nobody acted on. Most advice on slow moving inventory stops at "run a discount". The questions that matter to a finance team come earlier and later: how old is too old, is it a provision or a write-off, and what happens to the Goods and Services Tax (GST) credit already claimed?

This page gives you a report you can build in Excel, with notes on using TallyPrime's Stock Ageing report alongside it, a worked cost in rupees, and the rule that separates a provision from a write-off under Indian accounting standards.

It also answers the objection that comes up first: the stock might still sell. The report separates stock that is merely quiet from stock that has lost its buyer.

What counts as slow moving inventory, and how is it different from non-moving stock?

Slow moving inventory is stock that still sells, but slower than the pace you bought it for. Non-moving stock has had no sale in your cut-off period. Obsolete (or dead) stock has no realistic buyer at cost. Each needs a different action and a different entry in your books.

Definition

Months of cover Quantity on hand divided by average monthly sales: 600 units with 100 sold a month is six months of cover.

Definition

Net realisable value (NRV)

The price you expect to get in the ordinary course of business, less the cost to complete and sell the goods (Ind AS 2, Ministry of Corporate Affairs).

The common objection is "it may revive". Test it with three questions. Is there an order or forecast against it? Can you name a likely buyer? Is the product still current? Three "no" answers mean you are holding obsolete stock, not slow stock.

How do you build a slow moving stock report in Excel?

Export every item with its quantity, cost and last sale date, then calculate days since last sale and months of cover. As a starting point (our recommendation), mark an item "non-moving" at more than 90 days without a sale, and "slow" when cover is above six months.

A clerk at a laptop checks the stock shelf behind him, with a few boxes marked by pink tags.
The report starts from the physical shelf: every item is matched to its last sale and its stock left.

A: SKU (stock keeping unit, one line per product variant), B: category, C: quantity on hand, D: unit costYour stock export
E: stock value

=H2/3

J: months of cover

=IF(I2=0,"No sales",C2/I2)

K: status

=IF(G2>90,"Non-moving",IF(J2>6,"Slow","OK"))

Sort by column E, highest value first, and start with the ten items of highest stock value. In many businesses a small share of items holds most of the value, so check your own total before deciding how far down the list to go.

Set your cut-off from your own business. It should be longer than your supplier lead time plus the normal gap between sales for that item, so a spare part and a fast-selling consumable need different limits. The reorder point formula shows how to work out lead-time demand. For a whole-business view, use inventory turnover days.

Using TallyPrime alongside it. TallyPrime's Stock Ageing Analysis report groups stock into 0 to 45, 45 to 90, 90 to 180 and 180+ day buckets by default. F6 changes the buckets, and F9 changes the ageing style: purchase date, expiry date or manufacturing date (TallyPrime Help). That tells you how long stock has been held. Pair it with last sale date from the Excel sheet, which tells you whether anything is actually moving.

How much does slow moving stock cost you every year?

Interest alone on ₹10,00,000 of stock held for a year is ₹1,00,000 at 10%, ₹1,80,000 at 18% and ₹2,80,000 at 28%. Our model is stock value multiplied by your annual borrowing rate. Storage, insurance and shrinkage come on top.

Annual borrowing rateInterest on ₹10,00,000 of stock, one year
10%₹1,00,000
18%₹1,80,000
28%₹2,80,000

As of May 2026, Shriram Finance quotes working-capital rates of around 8% to 10% for strong MSME (micro, small and medium enterprise) borrowers at public sector banks and 15% to 28% from non-bank finance companies (Shriram Finance). The table uses 10%, the top of the bank range, then 18% and 28% within the non-bank range. These are illustrations; use your own sanctioned rate, or the return you would otherwise earn if you fund stock from your own cash.

At 18%, that stock costs ₹15,000 a month before the rent on the space it sits in. Compare that with the discount needed to clear it, and the case for acting early is usually clear.

Should you make a provision or write slow moving stock off?

Make a provision while the goods are still on your shelves and might sell. Write off when you have decided they have no use and remove them from the books. Ind AS 2 (the Indian Accounting Standard on inventories) requires inventory at the lower of cost and NRV (Ind AS 2, paragraph 9).

Cost may not be recoverable when goods are damaged, partly or wholly obsolete, or their selling prices have fallen. The write-down is normally made item by item, and it is an expense in the period it occurs. If NRV later recovers, the write-down is reversed. Businesses that follow the older Accounting Standard 2 (AS 2) apply the same lower-of-cost-and-NRV principle.

Worked example (illustrative). An item costs ₹1,000. You expect to sell it at ₹700 and selling costs are ₹50, so NRV is ₹650. The write-down is ₹350 per unit. On 400 units that is ₹1,40,000 (350 × 400). The entry is a debit to inventory write-down expense in the profit and loss account and a credit to a provision for slow moving stock.

The standard asks for NRV, not a flat percentage. Age is the trigger for a review. If your policy uses age bands with rising provision rates, set the bands from how your own stock sells and apply them the same way every year. A policy you change each year invites questions.

An auditor will typically test four things. Run them yourself first:

  1. 1

    Ties to the ledger.

    The total of your ageing report matches the stock value in the books. Pass: zero difference.
  2. 2

    Last movement is real.

    Trace 10 items to their last receipt or sale. Pass: all 10 dates match the report.
  3. 3

    Past provisions were right.

    Compare earlier provisions with actual disposal prices. Pass: stock sold at or above its carrying value after provision.
  4. 4

    Policy is consistent.

    Pass: the same bands and method as last year, or a documented reason for the change.

What do GST and income tax do when you write off or dispose of slow stock?

Credit is blocked when goods are destroyed, written off, or given away as gifts or free samples. Section 17(5)(h) of the Central Goods and Services Tax (CGST) Act, 2017 blocks input tax credit (ITC), the GST you claimed on purchases, on goods "lost, stolen, destroyed, written off or disposed of by way of gift or free samples" (CBIC, section 17).

Selling the goods, even at scrap value, is a taxable sale and does not trigger section 17(5)(h). On our reading, an NRV provision leaves the goods on your books, so it is not a write-off and does not trigger the reversal either.

As an illustration, take 400 units costing ₹1,000 each (₹4,00,000 in total) bought with 18% GST. If you destroy or donate them after claiming full credit, you reverse ₹72,000 (4,00,000 × 18%) in your GST return for that period. If you sell the same units to a scrap buyer, you charge GST on the sale and reverse nothing. Plan the route before you act, and confirm it with your chartered accountant (CA).

Income tax follows a valuation rule. As of October 2026, the Income-tax Act, 2025 has applied since 1 April 2026, and its section 277 corresponds to section 145A of the 1961 Act (TaxTMI), under which closing stock is valued at the lower of cost and NRV (Income Tax Department). A write-down to NRV is therefore a valuation question, not only a provision. Whether a flat-percentage provision is accepted is a separate question that depends on the facts, so confirm it with your CA. Keep this evidence for any write-off:

  • A management approval for the write-off.
  • Your NRV working.
  • A physical verification report.
  • A destruction certificate or scrap sale invoice.
  • Photographs of the goods.

How do you sell slow moving products without giving away the margin?

Set the floor price from your best real alternative, not from what you paid. Our recommendation: the floor is the best net offer you can get from a liquidator or supplier return, plus the carrying cost you avoid each month (stock value × monthly interest rate). Sell any lot at or above that floor. Use NRV for the accounts, not for the price.

For a ₹4,00,000 lot at 18% a year (1.5% a month), the avoided carrying cost is ₹6,000 a month (4,00,000 × 1.5%). Work down this order and stop when the stock clears:

A trader and a buyer inspect a wrapped pallet of cartons at a loading dock beside a waiting truck.
A firm floor price lets the trader weigh a liquidator's offer against the cost of holding the lot.
  1. 1

    Sell to existing customers first.

    Offer it to buyers who have bought the item or its neighbours before.
  2. 2

    Bundle.

    Attach slow items to a fast mover so the discount sits on the slow line only.
  3. 3

    Return to the supplier.

    Ask for credit, even partial.
  4. 4

    Liquidate.

    Sell to a trade buyer or marketplace at a floor price you set in advance.
  5. 5

    Donate or destroy.

    This is the last step, and it triggers the ITC reversal above.

How do you stop slow moving inventory building up again?

Fix it at the purchase order. In our experience, slow stock is mostly a buying decision made months earlier, so reorder from real lead times and sales rates, not from a feeling that you should keep some on hand. The reorder point formula turns lead time and demand into a trigger quantity.

Three habits keep the report short:

  • Review the ten highest-value items every month.
  • Do not reorder any item flagged "Slow" until its cover drops below your limit.
  • For batch and expiry items, sell the earliest-expiring stock first, known as FEFO (first expired, first out); see batch expiry software for FEFO operations.

Frequently asked questions

No. A provision for slow moving stock is deducted from the inventory figure, so inventory is shown at the lower of cost and net realisable value. It is a valuation adjustment on the asset, not an amount you owe to anyone.
Yes. If net realisable value recovers, Ind AS 2 requires the write-down to be reversed, limited to the amount of the original write-down. The reversal reduces the expense in the period it happens.
Yes. A single 90-day rule suits fast-selling goods but flags slow-selling spares too early. Set each category's cut-off from its supplier lead time plus the normal gap between sales, and review it once a year.
Not quite. Non-moving stock has had no sale in your cut-off period but may still revive. Dead stock is non-moving stock with no realistic buyer at cost, which is what we call obsolete stock in the table above.
It can. Lenders may exclude slow or obsolete stock when they calculate how much you can draw against stock. Check the terms of your sanction letter, and keep your ageing report current so you can show the bank what is saleable.
