A streamlined 6-step process ensures every order ships fast, accurately, and with full visibility.

You provide a BOM (bill of materials). We map components, quantities, and assembly steps.

All components received, counted, and staged by kit type.

Trained staff assemble kits per BOM. Quality checks at each stage.

New kit SKU barcoded. FNSKU applied if FBA-bound. UPC assigned if needed.

Random sample inspection. Scan verification of every completed kit.

Finished kits enter WMS inventory as a sellable SKU, ready to ship.
Purpose-built infrastructure, real-time technology, and hands-on service - all under one roof.
2-item bundles, gift sets with 8+ components, promotional kits, welcome boxes - any bill of materials, any complexity.
Need to change kit contents monthly? Seasonal variations? We update BOMs quickly and can run multiple kit versions simultaneously.
Whether you are shipping 200 orders a month or 200,000, our infrastructure scales with you.
DTC and Amazon sellers who want to offer product bundles without managing assembly in-house.
Kitting is time-intensive and error-prone when done in-house. Assembly line efficiency requires volume, trained staff, and quality control processes that most brands cannot sustain without dedicated warehouse space.
3PLCity runs kitting operations at scale. Our assemblers are trained on your BOM, our WMS scans and verifies every finished kit, and our process handles any component count or assembly complexity. You get professional kit production without the overhead of running your own assembly operation.
