How to Audit a Supplier Tech Pack: What Should They Send Back?

Most buyers read a returned pack for the price and for the lead time, and both of those are the least informative things on it. The informative part is the component section, because that is where a supplier either commits to a reference or does not.

The reason it matters is that a component line answered with a reference is a commitment that can be checked at inspection, and a line answered with a description is not. Where half the lines are descriptions, half the specification is undefined at the point the price is agreed.

The audit below is a read of the return rather than a visit. It takes twenty minutes, it is done at quotation stage rather than after sampling, and it is the least expensive indication of how the next two months will go.

What Should Come Back and By When?

A return sheet: the pack with every raised point answered, a materials list with a reference per line, a cost breakdown, and a sampling date. Where the pack asked for a test figure, the return carries a figure rather than a promise to test later.

The timing matters as much as the content. A return that arrives within two working days usually means somebody read the pack and answered it from a system. One that arrives after a week often means the pack went out to component suppliers and came back, which is fine, and it is worth knowing which happened.

The third thing that should come back is a question. A pack that generates no question at all has either been perfectly written or skimmed, and the second is far more common. A supplier who asks two sharp questions has read the document.

What Does a Complete Return Sheet Contain?

Sixteen fields, each with a reference rather than a description. Shell and lining by reference. Every trim by reference. Every hardware part by reference with a finish and a figure. Foam by type, density and thickness. Thread by ticket. Zipper by the six fields. Artwork process named. Packing stated. And a lead time with a start condition.

The remaining fields are the ones most often missing, and they are the ones that decide whether the price holds: what is included in the price, what the minimum applies to, what the sampling figure covers, and what happens to a surplus on a dyed component.

A return that covers all sixteen is not common and it is not required. What matters is the shape of the gaps: a supplier who answers fourteen and flags two as open has read the pack, and one who answers four and repeats the buyers words on the rest has not.

How Is Each Field Read When It Comes Back?

By asking one question of each line: could this be checked at inspection? A reference can be, a figure can be, a description cannot be. That single test sorts a return sheet in a couple of minutes and it does not require any product knowledge at all.

The second read is for internal consistency. A return that names a shell at 600 denier and a unit weight that implies 300 denier has answered two questions from two different places, and the discrepancy is where a substitution will appear later. Cross-checking the weight against the materials is a five-minute exercise.

The third read is for what changed. Where the buyer specified one thing and the return says another, the return should say so rather than quietly substitute it. A changed line with a note is a professional answer; the same line changed silently is the single clearest warning on the document.

What Counts as a Red Flag on a Returned Pack?

Five answers. "As specified" on a field the pack left open, which means the field was not read. "Good quality" or "high quality" in place of a reference, which means there is nothing to inspect against. A test figure with no method, which means it cannot be reproduced.

The fourth is a price with no breakdown. A single unit price with no material, labour and trim split cannot be reviewed, cannot be compared across suppliers and cannot be adjusted when a component changes. It is the answer most often given and the one least worth accepting.

The fifth is a lead time with no start condition. Forty days from when? From approval, from deposit, from material arrival? Each is a different date and the difference between the first and the last is often two weeks.

How Is a Vague Return Answered?

With the same question, narrowed. Where a supplier returns "metal hardware", the answer is a request for the part reference, the finish and a pull figure — three specifics rather than a repeat of the original request. A supplier who answers the narrowed question has the capability; one who returns another description does not have the part.

The second move is to offer a reference rather than to demand one. Where a programme already uses a zipper or a webbing it is happy with, naming it in the request converts an open question into a yes-or-no, and the answer is immediate. That is faster for both sides and it produces a comparable quote.

The third move is to accept a description and convert it into a figure. Where a supplier will not name a part, a pull figure in newtons and a cycle count achieve the same thing: whatever arrives has to meet the number. That is the fallback, and it is a good one.

What Does the Supplier Add That the Buyer Did Not Ask For?

Usually a construction suggestion, and it is worth reading. A supplier who proposes a bound seam where the pack specified an overlocked one, or a reinforcement at a load point, is describing a failure they have seen. That is the most valuable free information in the whole exchange.

The second addition is a material proposal, and it carries more caution. Where a proposed material costs less than the one specified, the reason is usually a lower weight or a different construction, and the question to ask is which. A proposal is not a substitution where it is stated; it only becomes one where it is not.

The third is a minimum. A supplier who states a component minimum above what the order consumes is giving the buyer the chance to decide rather than discovering the surplus later. Where that information appears on the return, the return was written by somebody who has costed the job properly.

How Is the Return Used to Set the Sampling Window?

Directly. Sampling runs 6-10 working days from a signed pack, and that window assumes the materials are available. Where the return flags a component that has to be sourced or dyed, the window starts when that component arrives rather than when the pack is signed.

The second adjustment is for a complex construction. A bag with a welded wall, a moulded part or a tooled hardware item carries a longer sampling window of 12-15 working days, because those steps cannot be compressed. Where the return names one of those, the date should be set from the return rather than from the default.

The third is the number of rounds. A return that is complete and specific is usually followed by a sample that is close, and one that is vague is usually followed by two or three rounds. Setting the expectation from the return is more honest than setting it from the default window.

What Does a Good Return Tell You About the Line?

That the specification is held somewhere other than in one persons head. A return that names mills, part references and test figures comes from a place where components are recorded, and a place that records components can reproduce a run. That is the single most useful prediction available before an order is placed.

It also tells a buyer how the second run will go. A supplier who returns references on the first enquiry can be held to them on the second order; one who returns descriptions cannot, and the second run will drift for the same reason the first one was hard to pin down.

The third thing it predicts is the inspection. Where the pack and the return both carry figures, an inspection at AQL 2.5 under ISO 2859-1 has something to measure against, and a failed result is defensible. Where neither does, the inspection is a matter of judgement.

How Is the Audit Recorded and Reused?

As a scored return sheet kept with the style. Sixteen fields, a mark for reference against description, and a note on the five red flags. One page, filed with the pack, and it is the reference for the next enquiry to the same supplier.

The reuse is comparative. Where a programme sends the same pack to three suppliers, three scored sheets side by side make the choice evident in a way that three prices do not. The price says what it costs; the score says what the buyer is buying.

The second reuse is at the second run. A return that was vague on hardware the first time should be checked on hardware the second time, and the scored sheet says so without anybody having to remember.

What Does the Return Tell You About the Price?

Less than buyers expect, and more than they read. A return carrying a breakdown shows material, labour and trim as three lines, and the material lines can be checked against the BOM in a way that a total cannot. Where a quote comes back as one figure, there is nothing to review when a component changes.

The second thing it shows is which lines are volatile. A return that flags a shell price as valid for thirty days is telling the buyer something true and useful. One that quotes a fixed price for six months on a commodity polymer is quoting something it may not be able to hold, and the difference between the two is visible on the page.

The third is what is excluded. Tooling, a setup charge, a dye-lot minimum and a certificate fee are four items that often sit outside a unit price, and where they are on the return two quotes can be compared honestly. Where they are not, the lower quote is not necessarily the lower cost.

The useful move is to ask for those four as separate lines rather than to argue about the unit price. They are a small part of the total and they are the part that changes between the first run and the second.

What Is the Short Rule for Auditing a Return?

Ask one question of every line: could this be checked at inspection? A reference and a figure can be, and a description and an adjective cannot be.

Then file the scored sheet. It is one page, it is reusable on every enquiry to that supplier, and it is the least expensive due diligence available before an order is placed.
