Build a representative buying basket
Start with recent purchases covering normal service and relevant seasonal demand. Record the product, supplier code, pack size, price basis and quantity used. Keep exceptional one-off purchases separate so the result reflects the operation you are reviewing.
Compare like with like
Match the required specification: ingredient, grade, size, preparation, usable yield and any brand requirement. Check whether the case contains the same number or weight of saleable portions. Samples and preparation trials help you judge proposed alternatives against the agreed standard.
Calculate the usable cost
Illustration only: a £30 pack with 5 kg net weight and 80% usable yield provides 4 kg usable product. The usable cost is £7.50 per kg. A £32 pack providing 4.5 kg usable product costs about £7.11 per usable kg. The higher-priced pack could therefore cost less in use, provided it meets the specification.
Include trimmings or other usable outputs consistently in the comparison. Do not count an estimated yield benefit as an achieved saving before testing it.
Weight prices by what you buy
Apply the agreed comparable prices to the same quantities. Add the basket totals before calculating a saving; do not average the percentage differences on small and large lines as if they represented equal spend.
If a comparable basket moves from £10,000 to £9,700, the price-only reduction is £300, or 3%. This is an example, not a DishLab performance claim. Separate delivery charges, rebates and other adjustments so the basis remains clear.
Check the commercial terms
Discuss delivery days, minimum orders, lead times, substitutions, shortage handling, payment terms, price-review arrangements and any required commitments. A price that cannot be maintained or delivered when needed is not a complete solution.
Agree how the project is funded
DishLab can negotiate with your current supplier to fund the agreed development project, or introduce a trusted national supplier. Funding, purchasing arrangements and the exact support included should be clear before proceeding. We look for savings where possible without promising a fixed outcome.
