Many shop owners sell well with money coming in every day, yet when it’s time to restock they have “no cash”, even though they made a profit. This usually comes from one place: money quietly tied up in “stock” (goods bought but not yet sold). This article explains what inventory value is, why shops must know it, and how to check stock easily so cash isn’t tied up.
What is inventory value?
Inventory value is the “money value” of goods still sitting in your shop right now, not yet sold. Put simply, it’s the money you paid to buy stock that is currently still on the shelf.
For a single product, it’s easy to work out:
Cost value on hand = quantity remaining × cost per item
For example, 20 bottles of beer left at ฿65 cost each → cash tied up in beer = 20 × 65 = ฿1,300. Add up every product and you get “how much cash is tied up in stock across the whole shop right now”.
Why must shops know stock value?
Knowing inventory value helps with 3 big things:
- Know where the money went: profit is fine but cash shrinks, because money has turned into “goods on the shelf”. Seeing this number helps you understand your shop’s cash flow.
- Catch dead stock: goods bought long ago that don’t sell are tied up cash at risk of expiring or going out of style. The sooner you spot it, the sooner you can clear it at a discount.
- Order more accurately: seeing what’s left, what’s running low, and what’s overstocked helps you avoid double ordering or running out.
For shops with hundreds of products (groceries, parts, clothing), not knowing stock value is like running the shop blindfolded.
3 numbers worth knowing about your stock
Don’t just look at “how many pieces left”, look at it as money from 3 angles:
- Cost value on hand = the cash actually tied up (quantity × cost): tells you cash flow
- Value if all sold = quantity × selling price: tells you how much your goods could turn into
- Profit waiting = value if all sold − cost value: tells you how much profit is still there to collect
For example, if goods have a cost value of ฿12,400 and would fetch ฿19,800 if all sold → there’s ฿7,400 of profit waiting. This set of numbers gives a far clearer picture than counting pieces alone.
How to check stock so cash isn’t tied up (without an expensive system)
- Count for real, on a cycle: at least once a month, count what’s left of your main products, then multiply by cost
- Record every buy in and sell out: stock in +, sold out −, so you get an accurate remaining count without guessing
- Separate “fast sellers” from “dead stock”: anything that hasn’t moved in 1 to 2 months, discount to clear or stop reordering
- Don’t order on a hunch: order from the real remaining count, so you don’t overstock and tie up cash
The key is “record fully”, because if you don’t know how much came in and went out, you can’t compute value on hand (read alongside: How to calculate shop profit).
Manage stock + see value on hand with Posless
Once you have a lot of products, counting by hand every time gets impractical. A tool like Posless has an “inventory mode” that helps you see stock value through the LINE you already use, with no POS hardware:
- Log stock in easily: type “receive”, pick a product, enter the quantity bought in
- Auto deduct stock on sale: every time you log a sale, the system reduces the remaining count for you, no recounting
- See value on hand instantly: type “inventory” to see all 3 numbers: cash tied up · what you’d get if all sold · profit waiting, broken down per item
- Doesn’t affect profit calculation: stock value is a separate view, and cost isn’t double counted against daily profit
Inventory mode suits buy and resell shops (grocery / minimart, clothing, cosmetics, parts, online stores), and you can switch it on/off. Make it yourself shops that sell fresh (cafés, food) don’t need to turn it on (read next: Opening a grocery store: what to prepare · Easy shop bookkeeping on your phone).
FAQ
Q: Is inventory value based on cost price or selling price? A: The standard is cost price (the money actually paid), because it reflects the cash tied up. The “selling price” is used to estimate how much you’d get back if it all sold. Look at both together.
Q: How often should I count stock? A: If counting by hand, at least once a month. But with a system that auto deducts stock on sale, you see the remaining count in real time without counting often.
Q: Do food shops / cafés need to track stock value? A: Cooking ingredients are hard to count as directly sellable pieces, so per item stock value suits “buy and resell” shops more. Fresh make shops are better off controlling ingredient cost per menu item instead.
In short: inventory value is the cash tied up in goods on your shelf. Shops that know this number manage cash, ordering, and dead stock far better. Start by recording buy ins and sell outs fully, then review value on hand regularly, and your shop will “know its real profit” and “know where the money is” at the same time.
