When The Supplier Changes Something

The bottle looks the same. It tastes slightly different, and a regular mentions it before anyone behind the bar has noticed.

Supplier changes are routine. Finding out about them last is the avoidable part.

The four that actually matter

Price. ⚠️ Rises arrive quietly on the invoice, and invoices are checked for total rather than for line-item change. A 6% rise on your highest-volume line is invisible this way and material over a quarter.

Formulation or specification. Guests notice this before staff do, because staff taste it in the middle of service and guests taste it against memory.

Delivery schedule. A moved day breaks a prep routine that was built around it.

Availability. ⚠️ The one that hurts on a Saturday. Usually there was notice, and usually it went to an email address nobody watches.

Why you find out last

Notices go to whoever set up the account. Frequently someone who left, or an address checked monthly.

Invoices are checked as totals. ⚠️ Nobody compares line prices against last month — which is exactly where the change is.

Deliveries are checked for quantity, not for specification. The box count is right; nobody reads the label.

Where to put the checks

Three, all small:

Compare line prices monthly against the previous month, on your top ten lines only. ⚠️ Ten lines, five minutes, and it catches nearly all of the money — the long tail is not worth the time.

One nominated address that is actually read. Not a personal address. Somebody's job.

A spec check on delivery for the small number of items where it matters. Not everything — the things guests would notice.

The conversation to have once

With each significant supplier, one question: "How will you tell us if something changes, and who will you tell?"

⚠️ Frequently reveals they have been sending notices to an address nobody reads, which is fixable in one minute and would have prevented the last three surprises.

When something has changed

Decide explicitly whether to accept it. A reformulated product is a new product; you would not have added it without tasting it.

If you accept, tell the staff. ⚠️ They will be asked, and "I don't know, it tastes the same to me" is worse than "yes, the supplier changed it".

If you do not, say so quickly. Suppliers respond to specific complaints from customers who noticed; the leverage decays fast.

The cost of finding out late

Money on prices, quietly, for however many months.

Guest trust on specification. ⚠️ Guests do not attribute the change to your supplier — they attribute it to you cutting corners, and that reading is very hard to correct once formed.

Three to hold

Line price change, top ten lines, monthly. The five-minute check that pays for itself.

Delivery shortfalls by supplier. Shows which relationship is actually reliable rather than which feels reliable.

Items where guests raised a change before you did. ⚠️ Should be zero. Usually is not.

Where the record has to sit

Comparing this month's prices against last month's requires last month's to be readable in the same shape. Where invoices are filed as paper or PDFs, the comparison is technically possible and practically never happens.

tasteck keeps purchase records alongside the sales they support, so cost per item can be read over time rather than reconstructed from a folder.

The change was announced. It went to an address nobody reads, and you found out from a guest.
