The Bid Was Priced on Volume You Never Sent

The forecast that did not match the bid

Midway through a packaging transition, a natural foods brand sat down with its consultants and worked through an uncomfortable agenda item. The newly awarded corrugated supplier was receiving forecasts, that part of the machinery worked, but the numbers were substantially lower than the volumes they had bid against. The supplier's question was polite and pointed: do we have the business we won, or are you still buying from the incumbent?

Nobody in the room had done anything wrong. Purchasing was ordering where purchasing had always ordered. Old items ran out slowly, transitions waited on artwork and first articles, and some volume simply never got a cutover date. The award happened in a conference room; the volume was still following muscle memory.

Why the gap is a pricing event, not a paperwork lag

Here is the mechanism that makes this expensive rather than merely untidy. A supplier bidding on your full annual volume prices the whole system around that number: run lengths, changeover frequency, board buys, warehouse commitments, minimum order quantities. The unit price on the bid sheet is an output of that volume assumption. When actual flow comes in far below bid, the supplier is not being oversensitive; their run economics genuinely do not exist yet.

What happens next is predictable. First come the questions, exactly the ones this supplier asked. Then come the adjustments: MOQs enforced where they had been waived, lead times quoted where they had been absorbed, and eventually a conversation about repricing to actual volumes. Every week of gap gives the incumbent, who can see the business leaving, room to make selective retention offers on the SKUs that matter. The RFP you ran carefully six months ago is being re-run informally, one irritated conversation at a time.

The deeper issue is ownership. An award creates a to-be state. The order flow lives in the as-is state. Unless someone specifically owns moving each SKU family from one to the other, with dates, the two states coexist indefinitely, and coexistence is the expensive condition: transition-period pricing on the new business, legacy pricing on the old, and two suppliers each holding half a promise.

Closing the gap deliberately

The fix in this case was unglamorous and immediate: get both sides in one room, reconcile the bid volumes against the live forecasts item by item, and separate the gap into its real causes. Some volume had transitioned and the forecast feed understated it. Some was waiting on legitimate gates, tooling, artwork, first-article approval, each of which got a date. And some was still flowing to the incumbent for no reason anyone could defend, which is the category that only shrinks when a person is accountable for it.

The reusable structure is a bid-versus-flow review: monthly, per awarded supplier, comparing awarded annual volume, prorated, against actual receipts. It takes an hour. It catches the decay while it is still logistics rather than renegotiation. And it changes supplier behavior on its own, because a buyer who tracks the gap is a buyer whose bids can be trusted at face value next cycle, which is worth real basis points in the next RFP.

What a well-run transition reads like

The measurable version: every awarded SKU family has a cutover date before the award is announced. Bid-versus-flow variance is reviewed monthly and trends toward noise, single digits, within the agreed transition window. The incumbent's tail is a planned rundown with an end date, not a residual. And the new supplier's first-year business review opens with volumes that match the bid within a few percent, so the conversation is about the next year instead of relitigating the last one.

The volume number in a bid is usually treated as context. It is not context. It is a specification, and like any specification, it is either conformed to or quietly renegotiated. The plants that treat promised volume as a spec keep the prices they won. The ones that treat it as a hope pay for the same business twice.
