Quick answer: Supplier price tracking records what you pay for the same ingredient, in the same unit, by supplier and date. Divide the comparable line amount by its quantity before comparing invoices: a cheaper case can still cost more per kg if the pack is smaller. Review the unit-price change and its expected weekly cost before accepting it.
A price that rises AED 1/kg every two months looks like nothing in any single order - but over a year it has moved AED 6/kg, and on a high-volume ingredient that is a significant and invisible margin drain.
Cost creep can cause unexplained margin decline in a restaurant. It is not one large event - no single invoice that shocks you. It is dozens of small price movements across many ingredients and many suppliers, each individually unnoticeable, accumulating into a food cost that is materially higher than it was twelve months ago. TajerGo connects restaurant POS, stock and purchasing records; its supported supplier views provide recorded price history and material-change context for a buyer to review.
What is supplier cost creep and why is it hard to notice?
Cost creep is the gradual, incremental increase in what you pay for ingredients over time. It is hard to notice because:
- Each individual price move is small - a few fils per unit, a fraction of a dirham per kg.
- Each individual order looks roughly the same as the last one.
- There is no moment where the cumulative effect becomes obvious in a single transaction.
The effect only becomes visible in aggregate - in a food cost percentage that has drifted upward over months, or in a margin report that shows declining profitability without an obvious cause.
By the time most restaurant owners notice unexplained margin erosion and trace it to ingredient costs, several months of avoidable overpayment have already accumulated.
How does price tracking work in practice?
Supplier price tracking maintains a record of what you paid per item per supplier, with dates. This creates a price timeline for each ingredient. When a new purchase order is created or a new invoice is processed, the current price is compared to the previous price for the same item from the same supplier.
If the price has changed, the system flags it - specifically, with the previous price, the new price, the amount of the change, and the date. This converts an invisible drift into a visible event: something that happened on a specific date, for a specific amount, with a specific supplier and ingredient.
The flag does not automatically mean the price is wrong - suppliers have legitimate reasons to adjust prices, and commodity costs do move. But it means the change is seen and reviewed rather than absorbed silently.
How do you compare supplier prices when pack sizes change?
Match the same product, grade, pack size and base unit before treating two prices as comparable. If pack sizes differ, convert both to kg, litres or pieces. Use the same treatment of discounts, tax and delivery charges in both amounts; record those choices on the comparison sheet.
This is an illustrative comparison, not a supplier quote or a TajerGo customer result. Assume the same chicken product and grade, with both amounts on the same discount, tax and delivery basis:
| Record | Case amount | Quantity in case | Comparable unit price |
|---|---|---|---|
| Previous invoice | AED 240 | 10 kg | AED 24.00/kg |
| New invoice | AED 228 | 9 kg | AED 25.33/kg, rounded |
The case looks AED 12 cheaper, but it is 5.56% higher per kg. At 60 kg/week, the difference is AED 80 per week, calculated from the unrounded unit prices. If the product grade or usable yield has changed, investigate that difference before calling it a like-for-like price increase. If the previous price is zero or missing, record the AED difference and resolve the baseline instead of calculating a percentage.
What does cost creep look like in AED terms?
An example with one high-volume ingredient:
| Month | Price per kg (chicken breast) | Weekly usage | Weekly cost |
|---|---|---|---|
| January | AED 28.00 | 60 kg | AED 1,680 |
| March | AED 29.00 | 60 kg | AED 1,740 |
| May | AED 30.50 | 60 kg | AED 1,830 |
| July | AED 31.00 | 60 kg | AED 1,860 |
The move from January to July is AED 3.00/kg - a 10.7% increase. At the same 60 kg weekly usage, July costs AED 180 more per week than January. If the July price and usage continued for 52 weeks, that difference would annualise to AED 9,360; it is not a claim about what was spent during the six-month example.
This is one ingredient. A useful review ranks all ingredients by annual spend, then investigates the price changes with the largest AED impact rather than the largest percentage alone.
Which ingredients are most vulnerable to price creep?
Vulnerability to price creep correlates with two factors:
- High volume - the more you buy of an ingredient, the more each fils-per-unit change matters.
- Market-linked pricing - ingredients whose wholesale price tracks commodity markets (meat, seafood, fresh produce, cooking oil) are more volatile than packaged goods with more stable pricing.
The ingredients worth watching most closely are typically your top five by spend. For most UAE restaurants, these include fresh protein (chicken, meat, fish), fresh produce, and cooking oil. A 10% price increase on your highest-volume ingredient has a larger impact than a 30% increase on an ingredient you barely use.
How does price tracking support supplier negotiation?
Price history turns a negotiation from a memory exercise into a factual conversation. When you can show a supplier that the price per kg has moved from AED 28 to AED 32 over eight months - with specific dates and order references - that is a different conversation than "I feel like your prices have gone up."
The data also tells you whether the increase is specific to this supplier or reflects broader market movement. If your alternative supplier has also moved prices over the same period, the increase is probably market-driven and the negotiation should focus on locking in the current price or agreeing a ceiling. If only your current supplier has moved and the alternative has not, the negotiation is about the gap between them.
What is the difference between price tracking and invoice matching?
They serve different purposes and work at different time scales:
| Control | What it catches | Time scale |
|---|---|---|
| 3-way matching | Price and quantity discrepancies within a single order cycle | At the time of each order |
| Price tracking | Gradual price drift across multiple order cycles | Over weeks and months |
Both controls are necessary. Three-way matching catches the invoice that charges more than the PO. Price tracking catches the series of POs where the agreed price has been drifting upward without challenge.
What should you check before accepting a supplier price increase?
| Check | Record to keep | Decision it supports |
|---|---|---|
| Same item and unit | Item, brand/grade, pack quantity and base unit | Is this a genuine price movement or a changed product? |
| Comparable amount | Discounts, tax treatment and delivery allocation | Are both prices measured on the same basis? |
| Source and timing | Supplier, invoice or PO reference, date and quote validity | Is the old price still a fair baseline? |
| Operating impact | Unit-price change × expected usage for a stated period | Which change matters most in AED? |
| Alternative quote | Matching specification, availability and terms | Negotiate, accept or compare another supplier |
| Approved action | Named reviewer and agreed price or follow-up | Keep the buying decision traceable |
Start with one high-spend ingredient. Check the next invoice against this record, then repeat for the items with the largest expected AED impact. A lower quoted price is not automatically a better purchase if quality, delivery reliability or usable yield differs.
How TajerGo helps
TajerGo's purchasing and supplier workflow brings together available supplier price history, source records, dates, purchase orders and receiving. Material price changes can enter a review queue; a change is a prompt to investigate, not proof of overcharging. The supplier invoice agent prepares invoice details for review rather than replacing the original invoice or the receiving check.
Bring two invoices for the same ingredient to a walkthrough. Ask the team to show the recorded item and unit, price-history coverage, source document and the review step for your setup. Confirm the relevant plan on the pricing page; do not assume that external market prices or every supplier format are automatically available.
Frequently asked questions
How do I compare supplier prices with different pack sizes?
Convert both purchases to the same base unit, such as kg, litres or pieces. Divide each comparable line amount by its quantity, keeping discounts, tax and delivery treatment consistent. Check product grade and usable yield before concluding that a difference is a price increase.
How do I calculate a supplier price increase percentage?
Subtract the previous comparable unit price from the new unit price, divide by the previous unit price, and multiply by 100. Use a positive, known previous price. If the baseline is zero or missing, investigate it and report the amount difference instead of an undefined percentage.
How far back should price history go?
At minimum six months; twelve months is more useful because it covers seasonal commodity cycles. Ingredients that are subject to seasonal price swings - fresh produce, seafood - look very different with a twelve-month view than a two-month one.
Should I track prices across all ingredients or just the main ones?
Start with your top ten ingredients by spend. These are where price movements have the most impact on food cost. Extend to other ingredients once the tracking habit is established.
What should I do when a price increase is flagged?
First, check whether it was anticipated - did you discuss a price change with the supplier? If not, contact the supplier to understand why the price has moved and whether it is temporary or permanent. Compare against any available alternative supplier price. Decide whether to accept, negotiate, or switch volume.
Can price tracking tell me if I am overpaying compared to market rates?
Price tracking tells you your own price history and how it has moved. It does not automatically provide external market benchmarks. The practical comparison for most restaurant owners is against your alternative supplier's current quote rather than a published commodity index - which is why maintaining an active alternative supplier is valuable for this purpose.
