STOCK & COST3 Oct 202610 min read

Stop losing money to wastage: stock, purchases and cost control

Spoiled stock, missed deliveries and a vendor price that quietly crept up. How a connected stockroom shows where your margin goes.

Most restaurants know their sales. Far fewer know their real cost of sales, because stock lives in someone’s head and wastage is written on the back of a bill. The leak is rarely dramatic — it is a little each day: a tray dropped, a tomato box left out, an over-prepared batch, a delivery that was short by a kilo nobody checked.

Margin is made or lost in these small, repeated moments. The goal of a connected stockroom is not to police your team; it is to make the small leaks visible early enough to fix them.

The chain: from vendor to plate

Cost control works best when you can follow an ingredient the whole way. Navalyst POS connects the three places it passes through: the vendor you buy from, the stock you hold, and the sales that use it up.

Purchases add stock, sales deduct it, and wastage explains whatever is left over.
  • Record purchases against vendors, so you can see who you buy from, what you paid and what is still owed
  • Stock deducts automatically as items sell, so the count tracks service instead of lagging behind it
  • Log wastage with a reason — spoiled, dropped, expired, over-prepared — and see its cost, not only its quantity
  • Low-stock and out-of-stock signals appear before the lunch rush, not during it

Vendors and purchases: know what you paid

Supplier prices drift. A vendor who was cheapest in January is rarely cheapest in October, but without a record you cannot tell. Keeping purchases by vendor gives you a running history: what you bought, at what price, and how much remains unpaid. It also makes month-end less painful, because your accountant can see purchases beside sales instead of in a shoebox.

Wastage: the number nobody wants to write down

Wastage entries feel like confessions, which is why they are skipped. The trick is making them quick and blame-free: pick the item, enter the quantity, choose a reason. The reason matters more than the quantity, because it points at the fix.

A reason on every entry turns a loss into something you can act on.

A weekly routine that takes twenty minutes

  1. 1

    Check low and out-of-stock

    Start the week by scanning what is running low, so orders are placed before the shortfall, not after.

  2. 2

    Review wastage by reason

    Open the wastage report. Look for one or two reasons that dominate and ask what changed in the kitchen that week.

  3. 3

    Compare purchases with sales

    Place purchases beside sales. If purchases rise faster than sales, something is leaking.

  4. 4

    Check vendor balances

    See what you still owe each vendor and plan payments, so suppliers stay friendly and deliveries stay on time.

“You cannot manage what you do not record, and you will not record what takes more than ten seconds.”

Reading the numbers together

Reports show sales, profit, wastage and purchases side by side, so you can spot the week wastage jumped, the vendor whose prices moved, or the dish that sells well but earns little. Profit is only meaningful once cost is visible, and visible cost depends on stock being recorded as it moves.

Quick answers, in case the article left something open.

Ask us something else

STOCK & COST

Does stock update when an item is sold?

Yes. Stock is deducted automatically as items sell, so counts follow service without manual adjustments.

Can I record why something was wasted?

Yes. Each wastage entry carries a reason such as spoiled, dropped or expired, so reports show where loss comes from.

Can I track what I owe my vendors?

Yes. Purchases are recorded against vendors with what was paid and what is outstanding.

Can I see profit, not just sales?

Reports show profit alongside wastage and purchases so cost of sales is visible.
