Pick and pack as the contracted unit of work

Defining the chargeable event

A defensible definition names what triggers the charge, what is included within it, and what sits outside. Typical structures charge a base for the order plus an increment for each additional line, or an increment for each unit beyond the first on a line. Gift messages, serial capture, multi-parcel splits, hazardous handling and special packaging are usually extras. Rebuild each provider's quotation against a sample of your own order history rather than against an average order, because the average conceals exactly the orders that drive cost.

Order profile is the real cost driver

The work in an order depends on how many lines it holds, how far apart those lines sit, the size and weight of the items, and how much of the day's volume arrives before the despatch cut-off. A range extension, a promotional multi-buy or a shift towards larger items can move all of these without any change in order count. Providers notice this in their labour figures long before clients notice it on an invoice, which is why the assumptions behind the rate should be stated and reviewed.

Packaging supply, ownership and specification

Decide who buys cartons, void fill, tape and branded inserts, who holds the stock of them, whether the provider may substitute when an item runs out, and how consumption is charged. Providers buying on your behalf can achieve better purchasing power, at the cost of visibility over what was paid. Clients supplying their own materials keep control of presentation and cost, but then carry the responsibility for replenishing them before the site runs dry.

Accuracy, and what counts as an error

Order accuracy needs a definition that survives an argument: wrong item, wrong quantity, missing line, and damage in packing are different failures with different causes. Agree how errors are reported, what evidence is required, who bears the cost of putting each type right, and over what population the rate is calculated. A measure expressed against total units will almost always look better than one expressed against orders, so the choice is a commercial decision rather than a technicality.

Frequently asked questions

Which charging basis suits a single-item consumer operation?

A per-order structure with a modest line increment usually reflects the work well, because most of the effort sits in touching the order at all. Operations with many lines per order are generally better served by a structure weighted towards lines, since that is where their effort actually accumulates.

Can a provider reprice because the order profile changed?

Only if the agreement says so. That is the purpose of recording profile assumptions and a review trigger: it gives both sides a factual basis for reopening the rate instead of an argument about whether anything really changed.

Should packing materials be charged at cost?

Open-book supply at cost plus a handling element is common and easy to audit. What matters more is agreeing the specification and the replenishment responsibility, because a site that runs out substitutes something, and the substitution is what the customer sees.
