What goes wrong when you pick a prep center, and what we do about it.
Six problems sellers run into, and what we built for each.
I cannot tell which of these are real, or still open.
We list a center only after four checks: a real, registered business, a live site that names its Amazon prep work, FDA registration confirmed when claimed, and an editor's review.
146 of 806 operations we track were dead at last check →The listing was years out of date.
Every profile shows the date we last reviewed it. An old date turns into a visible warning on the listing instead of sitting there quietly.
Warning after 90 days, flagged after 180 →The quote looked cheap until the first invoice.
We print a center's published entry rate with the date we read it, and the form asks whether you will accept a setup fee or a monthly minimum before we rank anyone.
18 of 44 priced US centers charge a setup, registration or deposit fee (snapshot 2026-06-12) →I filled in one form and strangers started calling.
No prep center gets your name or contact details until you press Accept introduction on it. Press No thanks and it never gets them.
Shared only when you press Accept introduction
They were set up for a different kind of seller.
The form asks your monthly units, products, special handling and state, and the ranking is built from those answers. A center carries a hazmat, battery or FDA tag only after an editor has reviewed the claim.

Amazon ended its in-house FBA prep service. We keep a plain guide to what changed and what your options are, next to a checked list of centers that do the work.

Three steps. Your shortlist is ready when you finish.
One form, about 2 minutes, no password. Here is what happens, step by step.
Tell us what you ship.
Products, monthly volume, channels (FBA, Walmart, multi-channel), and the certifications you need (FDA, hazmat).
about 2 minWe rank on fit.
We rank the verified prep centers that fit your volume, geography, and certifications: up to 10, best fit first. No prep center can pay to be in that ranking or to move up in it.
when you finishYou choose, one at a time.
We send a summary of your answers, without your name, business or contact details, to up to 25 prep centers that fit. A prep center that wants the work accepts. Press Accept introduction on the ones you want to meet and No thanks on the rest; we email you and that prep center together.
your moveThe 4-point operator standard. Every listing is checked against all four before it goes live.
A site that no longer loads, or one that never names Amazon work, is a red flag. We run the registry and site checks before a listing goes live, automated liveness checks after, and we re-verify when a user reports a problem.
A registered, operating business.
State business registry plus LinkedIn-confirmed founders. No minimum age: where we can confirm the year a business started, its profile shows it, so you can weigh a new operator yourself.
Registry + LinkedInFDA registration, when a center claims it.
From the registration confirmation FDA issued to the operator; food facility registrations are not publicly searchable. A claim we cannot confirm is shown as operator-stated, not as verified.
Registration documentSite live and names FBA prep.
Domain resolves, the homepage returns HTTP 200, and the operator's own visible site text names its Amazon FBA prep service (Amazon, FBA or FNSKU). Generic prep or 3PL wording alone does not get a center listed.
HTTP 200 checkHuman editor review.
Cross-checked against r/FulfillmentByAmazon, BBB, and seller forums. Recurring unresolved complaints block the listing.
Editor sign-offInside verified centers.
Photos uploaded by the operators of listed centers. Each one opens the profile it comes from.
Recently verified.
A weekly automated sweep re-checks every published listing, and only a confirmed re-check moves a date. These are the most recent confirmed dates, newest first. Each row opens the profile that carries it.

What three verified centers charge per unit.
Per-unit rates read from each operator's own published rate page, with the date we read it and a link to the source. A center that does not publish a rate shows none.
Across the 3 centers below, published per-unit rates run from $0.75 to $1.75, depending on volume.

Up to 10 verified picks, ranked by fit.
About 2 minutes in the form. Free for FBA sellers. Prep centers can pay for an optional Featured placement or join our introduction plan; no prep center can pay for editorial ranking, a shortlist pick, or the verification itself.
Verified centers in the directory include
Browse all 369 verified US centers →Is it really free for sellers? What is the catch?+
Free for FBA sellers, always. Prep centers can pay for a clearly labeled Featured placement. For US requests on our current matching form, we send a summary of the seller's answers, without their name, business or contact details, to up to 25 prep centers that fit: our picks, up to 10, and the next ones in fit order. A prep center that wants the work accepts, and the seller chooses which ones we introduce them to. A prep center pays us a fee, shown on each request, only for an introduction we send after both sides accept (its first is free). A prep center in the US with an active paid Featured subscription pays for Featured instead. No prep center can pay for editorial ranking, a shortlist pick, or verification, and those are unchanged whether or not a prep center pays.
How is this different from a directory or Google?+
Google gives you a list. We give you a ranked shortlist of the verified prep centers that fit your answers, and we send a summary of your answers, without your name, business or contact details, to up to 25 prep centers that fit. A prep center that wants the work accepts, and you press Accept introduction on the ones you want to meet. Every prep center we list has already cleared our 4-point standard, so you skip the round of cold emails.
How long does matching take?+
Your shortlist is ready when you finish the form, about 2 minutes: up to 10 verified prep centers ranked by fit, and we aim for at least 5. Prep centers answer in their own time, up to 7 days, and your portal shows which ones accepted. You decide on each one yourself, one at a time: press Accept introduction and we email you and that prep center together. You take the calls from there.
What if the match is not a fit?+
Press No thanks on any prep center you do not want; it never gets your name or contact details. If your needs change, change your answers in your portal: your list is ranked again from the new answers.
Do you work with hazmat or FDA-regulated products?+
Yes. Flag it in the form and your ranking is built from that answer. Hazmat, battery and FDA tags on a listing are editor-reviewed.
