How Do I Stop Staff Over-Ordering? Purchase Approvals and Spend Limits for Restaurants

Picture a bistro where any order over $1,500 waits for the head chef’s tap, everything else goes straight to the rep, and on Wednesday the kitchen can see $2,300 left in the week’s budget before the Friday order. That is how you stop staff over-ordering: clear rules on who can order, restaurant purchase approvals only for the unusual, and a weekly number everyone can see. Keep it light, or the kitchen will work around it.

The usual story goes like this: three people can text the reps, nobody can see what the others ordered, and the dry store fills with a second case of saffron that nobody asked for. The invoices land a week later, the food cost % is up two points at month end, and nobody can say whose order it was or why.

Why does over-ordering happen?

Over-ordering happens because it is safer for the person ordering. Running out of something on a Saturday is visible and embarrassing; carrying too much stock is invisible until stocktake. So people round up, add a bit "just in case", and order again when they cannot see what is already on the truck.

The common causes:

• Too many people ordering with no shared view of what has been ordered.
• No visibility of stock on hand or stock on order, so orders are guesses.
• Rep upselling: a special on a case of 12, so the order becomes a case of 12.
• Pars set high and never reviewed.
• No feedback loop: the person ordering never sees the invoice or the waste log.

Stale pars are a common culprit; our guide to par levels vs forecast ordering covers how to reset them.

A quick way to find your own pattern: pull last month’s invoices and the waste log, and list the items that were binned or still sitting in the dry store at stocktake. Then note who ordered each one. In most kitchens the same three or four lines, and the same one or two people, account for most of it. That tells you where a rule is needed and where a conversation will do.

Which orders should go through restaurant purchase approvals?

Only the orders that are unusual should need approval. If every order waits for the owner, ordering stops whenever the owner is busy, and staff start phoning orders in to get around it.

A workable set of rules for a single venue:

Set the dollar threshold from your normal order sizes, so the large majority of routine orders go straight through without anyone touching them.

Then decide who can order at all. A common split: the head chef and sous can order food; the bar manager orders bar stock; the floor manager orders cleaning and packaging; casual staff can do counts but not send orders. Write it down and pin it near the pass.

Make approvals easy to give. A manager should be able to see the order, the supplier, the total and why it was flagged, and approve from a phone between services. If approving needs a laptop and a login, it will be done at midnight or not at all.

How do budgets work week to week?

A weekly purchasing budget is a dollar limit on what each venue, or each section, plans to spend with suppliers that week, set from forecast sales and your target food cost %. It turns food cost % from a month-end surprise into a weekly number people can steer by.

A worked example

These numbers are made up. Say a bistro forecasts $42,000 in food sales next week and targets a 30% food cost. Last week’s stocktake showed food stock slightly high, so the chef wants to run it down by $800.

The budget is forecast food sales times target food cost %, less the planned stock reduction: $42,000 × 0.30 − $800 = $11,800.

In Excel, with forecast sales in B2, target food cost % in B3 and planned stock change in B4 (negative to run down stock):

With B4 at −800 you get $11,800. Track spend against budget as orders go in, not as invoices arrive. By Wednesday, if the venue has committed $9,500, the chef knows there is $2,300 left for the Friday and Saturday orders.

Some practical points:

• Adjust for the week. A week with a big function needs a higher budget, set from the function’s sales.
• Recheck the target when prices move. The ABS reported food and non-alcoholic beverage prices up 3.0% in the 12 months to August 2026, so a budget copied from last year’s spend will run short unless menu prices moved too.
• Split by category if it helps: proteins, produce, dairy, dry goods, bar.
• Do not make the budget a hard block. Running out on a Saturday costs more than going $200 over. Use it as a warning that needs a reason, not a wall.

The budget is steering a big number. The ATO’s small business benchmarks for restaurants put cost of sales at 31% to 39% of turnover, depending on business size (2023-24 tax data, food and drink together), and the R&CA 2024 Industry Benchmarking Report found almost 30% of Australian hospitality businesses surveyed made a loss in 2023-24. Purchasing is one of the few big costs a chef controls week to week. For more on the basics, see five golden rules for food cost control.

How do groups use a central purchaser?

Groups use a central purchaser to place or approve orders for several venues, so prices, suppliers and spend are managed in one place while each venue still says what it needs. Venues raise orders; the purchaser checks them against budget and the agreed supplier list, combines where it makes sense, and sends.

What a central purchaser typically does:

• Holds the approved supplier list and agreed prices, so venues do not drift to a different supplier at a higher price.
• Reviews orders in a queue, with spend rules and budgets per venue.
• Spots duplicate or oversize orders across venues.
• Handles price changes with reps, once, for the group.

The risk is that the purchaser becomes a bottleneck. Keep routine orders under the threshold flowing straight through, set a clear cut-off time for review each day (for example, orders reviewed by 1pm go out for next-day delivery), and give a named back-up approver for days off. Once orders flow through one queue, the same data lets head office compare venues fairly across the group rather than on raw food cost %.

How Restaurant AI Manager helps with purchase approvals

Restaurant AI Manager, Open Pantry’s AI restaurant operations software (Open Pantry is an Australian ordering and operations platform for food and beverage suppliers and the restaurants they supply, founded in 2018), includes approvals, budgets and spend rules. Groups get a purchaser queue with spend rules and budgets for each venue. Orders and invoices can be approved from your phone, and nothing goes to a supplier until someone presses Send. That includes the forecast orders it drafts; if that is your bigger worry, read whether it’s safe to let AI order stock.

Roles control what each person sees: chefs see food cost, not wages, and floor staff see stock, not prices. Every change is logged with who, what and when. For groups, see multi-location procurement, or try the free live demo with no sign-up and pick the owner or group role.

In summary: restaurant purchase approvals that don’t slow service

Decide who can order, let routine orders through, and send only the unusual ones for approval: over a value, off-list or from a new supplier. Restaurant purchase approvals and a weekly budget tied to forecast sales keep spend in line without holding up the pass.
