The direct answer: nothing your sourcing agent does is free. Free sampling, free QC, free warehousing, free translation, no service fee: all of it is funded from the margin built into your unit price, which means you are paying for every one of these services in the single place you cannot see an itemized bill. "Free" is not generosity. It is the pricing model, and it is the most expensive way to buy services, because it removes your right to ask what any of them cost or how well they were done.
The catalog of free
The list is familiar to anyone who has worked with a full-service agent. Free samples, or "sample cost refunded on order." QC inspections included. Consolidation and warehousing included. Translation, factory visits, photos from the floor: included. And the flagship line: "We don't charge you anything. We only make money when you do."
Each item on that list is real work done by real people who are really paid. The question an invoice would force (what does this cost, and is it worth it?) never gets asked, because there is no invoice. There is only a unit price with everything inside it.
What "included" actually costs
Run the arithmetic once and the word "free" changes flavor. Say the services baked into your pricing amount to $0.30 per unit, a modest figure for sampling rounds, inspections, and handling. On a 50,000-unit year, that is $15,000 of services you bought without a quote, a scope, or a deliverable. Would you approve a $15,000 invoice for QC and sampling without asking a single question about what you get for it? That is what "included" means: the invoice you never saw and therefore never questioned.
And because the services are funded by the margin, they scale with your volume, not with your needs. Double your orders and you have doubled your QC budget without anyone asking whether the QC got any better.
Free means unaccountable
The deeper cost is not the money. It is what "free" does to the quality of the work.
A paid service has a scope, a standard, and a client to answer to. A free service answers to whoever funds it, and what funds it is the margin, which is only realized when the goods ship. Follow that incentive to its end: the "free" QC inspection is performed by someone whose economics improve when the order moves and suffer when it stops. A defect found late in production is a threat to the very margin that pays the inspector's employer. You do not need to assume bad faith; you only need to notice that nobody in that chain is paid to stop a shipment on your behalf.
This is why "free QC" reports so often share a certain quality: thin, cheerful, and delivered close enough to the ship date that acting on them is impractical. The report is not lying, exactly. It is answering to its funding.
The reframe: give every free service its invoice
Here is a useful exercise for your next agent conversation. Take each included service and ask it three questions, as if it were a vendor: What would this cost if I bought it directly? What would I demand from it: scope, evidence, timing? And who does the person doing it actually answer to?
Third-party QC firms publish their rates, so the first question has a market answer. The second question usually reveals that you would demand far more than you are getting: timestamped photos, measurable AQL results, reports early enough to act on. The third question is the one that matters: in the free model, the answer is never "me."

What the visible version looks like
The alternative is not "pay for everything separately and drown in invoices." It is one visible fee, with the services under it scoped and accountable to you.
That is how FMT Flow is built. You pay your supplier directly, at a price you negotiated with it (no margin for services to hide in), and you pay us a fee you can read on one line. The people doing your follow-up and QC oversight are part of your team: their reports answer to you, land in a system you can open at any hour, and are logged next to every decision, in time to act rather than after the fact. Our fee is a published rate on what you ship, so we won't pretend a stopped shipment costs us nothing. The difference is where the result lands: in your system, the day it is found, with the decision yours to make.
If you have never priced your "free" services, it is a clarifying afternoon. Talk to an FMT Architect: we reply within one business day, and we will tell you what the visible version would look like for your volume.
