FBA prep centers in Michigan.

TurnKey Prep & Ship is a small Amazon FBA and Walmart WFS prep service in lower western Michigan, online since March 2025. It began as a books-and-media specialist and still runs that lane: per-item prep for books, DVDs and CDs at $1.50, including inspection, grading and a counterfeit check before FNSKU labeling. Its site now also covers general merchandise, from online and retail arbitrage to wholesale and private label, with liquidation loads reviewed case by case, at $1.00 per unit or $0.90 above 1,000 units a month. It receives 7 days a week and states processing within 48 hours, with a 24-hour rush for $0.25 more per unit. FBM fulfillment, returns at $1.00 per unit and storage with the first 14 days free sit alongside, and there is no setup fee and no monthly minimum. Two honest cautions: the operation is young (the founder's stated 12 years of e-commerce experience predates this business, which we date to 2025), and it publishes a state-level location only, no city or street address.

MI FBA Prep is a prep-and-ship center in Lapeer, Michigan handling Amazon FBA inbound prep: receiving, inspection, counting, storage, FNSKU labeling, poly bagging, bundling, and shipment to Amazon within 24 to 48 hours via UPS or LTL. Pricing is flat per unit with no hidden fees and a one-time $25 account-opening fee, plus 14 days of included inventory storage. The center works with new and international sellers and accepts pallets and freight, but does not take retail arbitrage, liquidation products, or book sellers at this time.

Michigan-based FBA prep center operating since 2005, owner-operated by Nathan and a small team. Specializes in small-to-mid wholesale and private-label Amazon sellers who want direct phone and email access to the operator. 24 to 48 hour turnaround. 14 days inventory storage included on every tier. Repeatedly recommended on FBA seller forums and podcasts; the personalized-service position is the moat.

Qualfon Logistics is the fulfillment arm of Qualfon, a business-process-outsourcing company headquartered at 13700 Oakland Avenue in Highland Park, Michigan, with facilities listed in Michigan, Pennsylvania and Nevada. Marketplace prep is one of four service lines alongside 3PL fulfillment, freight optimization and value-added services. The prep page covers Amazon FBA, FBM and Seller Fulfilled Prime, labeling, polybagging and protective packaging, bundling and kitting, carton prep and shipment preparation, inventory routing and compliance, and quality inspection, and it tracks Walmart's separate labeling and pallet standards as well as TikTok Shop's. One of its two case studies describes assembling 1 million kits and processing 3 million individual products for a single program. Cautions. The logistics site claims 40 years as a fulfillment operator while Qualfon's own corporate about page dates the founding to 1995, a gap of about nine years between the operator's two websites. There are no published prep rates. The positioning targets brands scaling past what a smaller 3PL can handle, so smaller sellers may not be a fit. No phone is published on the logistics site and the one testimonial is unattributed.

Encore Business Group is a 3PL in Kentwood, Michigan that runs DTC e-commerce fulfillment, subscription box packing, warehousing and an eBay consignment store next to its Amazon FBA and Walmart WFS prep line. The registry dates the LLC to May 2015. It began as contract assembly and kitting for manufacturers; its archived homepage lists Amazon FBA prep by June 2022. Commercial property listings show the Patterson Avenue address as a multi-tenant warehouse building completed in 2023, and the operator says it moved into 20,000 sq ft there in March 2024. The prep line covers private label, wholesale, retail and online arbitrage: receiving and inspection, FNSKU labeling, sticker removal, polybagging with suffocation warnings, bundling and multipacks, bubble wrap, and building the shipment in Seller Central or InventoryLab, with damage photos emailed. Rates are published: $1.50 per unit under 100 items a shipment, falling to $0.75 above 1,000, and $2.00 per unit for arbitrage prep, plus a $50 monthly subscription; 7 days of storage is included with prep. Cautions: prep runs 1-2 times a week depending on volume, not daily. ISO 9001 certification and the 98% accuracy and 99% on-time figures are the operator's own and we have not verified them. Prep is one of several lines here, so ask how FBA shipments are scheduled next to DTC and consignment work.

Shiplakes is a founder-run 3PL in Warren, Michigan, built for brands shipping 50 to 1,000 orders a month, running DTC pick and pack, inventory management, returns and Amazon FBA prep. The prep page sets out the whole inbound path rather than a feature list: an intake call covering catalog and restricted categories, limited Seller Central user permissions so the team can build shipments on the seller's behalf, inbound receiving with inspection and unitizing in 24 to 48 hours, FNSKU labeling with polybagging, bundling and shrink-wrap as required, shipment creation in Seller Central including fulfillment center selection and carton label generation, Amazon Partnered Carrier handoff, and reconciliation of unit counts against Amazon's received count. Prep is priced at $1.00 a unit falling to $0.80 above 2,000 units a month, with shipment plan creation at $20 and LTL pallet prep at $35. Supplements, beauty and electronics are named as core categories. Cautions. The domain is only 13 months old and no Michigan registry record was reachable without a browser, so the operating record is short and thinly documented. This is a small operation by design.

GrowthSpoke is a Grand Rapids, Michigan 3PL running e-commerce, retail, subscription box and TikTok Shop fulfillment, kitting and repackaging, with Amazon FBA prep as one of ten named service lines. The prep page sets out five concrete pieces of work: holding FBA inventory in the Grand Rapids warehouse until it ships, kitting and dekitting into bundles, sets and variety packs, case and carton forwarding labeled to Amazon's guidelines, repackaging to Amazon's packaging specifications, and barcode labeling covering both UPC and FNSKU. There is no minimum storage or order volume. The company publishes an eleven-person leadership team by name and holds an active Michigan registration. Cautions. The GrowthSpoke name and Michigan entity both date to 2025. The operation is older: the same Grand Rapids warehouse and Amazon FBA prep line traded as Sherpack until August 2025. Ask about the rebrand if contract continuity matters. The prep page describes a 211,000 sq ft warehouse; the building at the published address is documented at 140,000 sq ft in commercial listings and Colliers' West Michigan report. FDA registration and USDA organic handler status are claimed on the homepage as badges and are recorded as the operator's statement, not as verified. No email is published, so the phone line and the form are the only ways in.
