Our editorial directory of pure FBA prep specialists. Each entry has cleared at least one of our 5 verification checks within the last 30 days. More added weekly: we publish what we verify, not what we scrape.
How rankings work. Rankings on this page are editorial; we choose them on the criteria below (verification freshness, service breadth, capacity, reliability). Featured listings, when present, are clearly labeled both at the top of the page and on the entry itself. The methodology, criteria, and exclusions stay editorial regardless of any featured placements. New to the category? Start with what FBA prep is. Otherwise, read our full editorial methodology.

| Rank | Center | Capacity |
|---|---|---|
| #1 | MyPrepCenter | |
| #2 | WestFBA | |
| #3 | FBA In and Out |
We score on four weighted criteria, refreshed on the same cadence as our verification sweep (weekly). Centers that fail any single criterion don't appear here. They appear in exclusions instead. Centers that pass all four but score low on the composite still appear, just lower.
Days since our last passing verification check. < 30d earns full credit; 30–60d partial; > 60d disqualifies.
Distinct services we've confirmed (prep, kitting, FNSKU, hazmat, photography, etc.). More services = more credit, capped at 12.
Self-reported and corroborated against seller-forum data. Centers that overstate this drop in rank when we catch the mismatch.
FDA registration confirmed (if claimed), certifications current, no flagged checks in 90 days, phone answered within 2 rings.
Small Michigan-based shop operating since 2005, the longest track record in our directory.
Why we ranked them here: Owner-direct relationships with sellers; markets fast turnaround and direct phone/email access rather than a support-ticket layer. Listicle quotes $1.25 to $2.05 per unit. Best fit for small-to-mid sellers who want a team that will actually pick up the phone. Independent listing (not a 3PL); FBA prep is what they do.
California importer specialist built for high-volume container intake at West Coast ports.
Why we ranked them here: California-based with explicit positioning around container unloading and large-scale shipments through West Coast ports. Has monthly volume minimums; not a fit under ~1,000 units/month. Listicle quotes $0.75 to $3.00 per unit depending on complexity. Strong choice if your inventory ships from China and lands in LB/LAX.
Orange County small-shop running a documented three-step receive/prep/ship workflow.
Why we ranked them here: Port-adjacent in Orange County, CA, a practical advantage for Southern California importers shipping through LB/LAX. Handles inspection, FNSKU labeling, packaging, and compliance checks. Listicle doesn't disclose pricing; call for a quote. Good middle option for SoCal sellers who want a smaller shop than the bigger California prep operations.
We name names: both the candidates we excluded and the reason. The 3PLs we recommend separately (with outbound links) live on /fba-prep-3pl/.
Failed our pure-FBA-prep classification test (3PL or fulfillment platform, not pure prep)
Imported amzprep.com's published 'Best 19 Amazon FBA Prep Centers' index as a candidate pool. 15 of them (including ShipBob, Ryder, Stord, DCL, Flowspace, ShipMonk, MyFBAPrep, eFulfillment Service, ShipHype, Simpl Fulfillment, AMZ Prep, YYZ Prep, Fulfillment-Box, Red Stag, Buske) primarily market themselves as 3PLs or fulfillment platforms with FBA prep as one offering among many. We list them as recommendations on /fba-prep-3pl/ instead. The 3 above are our pure-FBA-prep cohort.
Each change to the cohort is logged here with the date and reasoning, so anyone bookmarking or citing this page can see the state at a given time.
Initial cohort published: 3 pure FBA prep centers (MyPrepCenter, WestFBA, FBA In and Out). 15 candidates from amzprep.com archived as non-pure-prep (3PLs or platforms); see exclusions below. More added weekly.
