Kitting, bundling and multi-packs, Miami FL
FBA Kitting and Bundling Service in Miami
FBA kitting and bundling: kits and multi-packs from 2 to 24 units, built and labeled with the kit's own barcode
Amazon SPN Certified · 24-36h prep window · Net-30 terms
PrepVia builds bundles, multi-packs and custom kits for Amazon sellers in one warehouse in Miami. Components are counted at receiving, and in the PrepVia app you see what arrived against what you sent. The kit is assembled to a written procedure, and the kit barcode is applied and verified by scan. The finished kits are boxed, the box content goes to Amazon through our own Amazon SP-API integration, and the freight goes on the Amazon partnered carrier when Amazon offers it. The difference between the three formats is on the kitting vs bundling guide.
SLA definition and production numbers are published on the facts page and republished when they change.
What is the difference between a kit, a bundle and a multi-pack on Amazon?
Three formats, one rule: the unit Amazon receives must carry one barcode and arrive as one piece.
| Format | What it is | How it is labeled and packed |
|---|---|---|
| Bundle | What it is: Two or more different products sold together as one listing, under the seller's own ASIN and the seller's own barcode. | How it is labeled and packed: One kit barcode on the outside. Component barcodes covered. A note that the set is not to be separated. |
| Multi-pack | What it is: Several units of the same product sold as one listing, for example a 3-pack or a 12-pack of one SKU. | How it is labeled and packed: One barcode for the pack quantity, not the single unit. The single-unit barcode is covered. |
| Kit | What it is: An assembled set with components, inserts and packaging, built to a written procedure before it ships. | How it is labeled and packed: Same as a bundle: one barcode, components covered, packaging closed so the kit arrives as one unit. |
Amazon treats a bundle or a multi-pack as one product with one barcode. The packaging has to keep the set together through the fulfillment center. That is why the kit is closed in a poly bag, a shrink wrap or a box. The outside carries a note such as "Sold as set, do not separate".
Component barcodes are covered so an associate scans only the kit barcode. When Amazon changes a packaging rule, the build sheet for the affected kit is updated before the next batch. When a bundle beats a multi-pack is explained in the kitting vs bundling guide for 2026.
How does PrepVia build kits at volume?
Six steps, the same for a hundred kits and for ten thousand. The count is carried from the dock to the box. You register the components in Send to PrepVia and ask for the shipment in Send to Amazon, with the prep notes for the kit.
Step 1
One written procedure per kit
Each kit configuration gets a build sheet: components, quantities, orientation, packaging, inserts and the barcode to apply. The floor builds from the sheet, not from memory.
Step 2
Components counted at receiving
Every inbound is counted against the packing list before assembly starts. The app shows expected against received units for each component, and a warehouse receipt in PDF once the shipment closes.
Step 3
Assembly in batches by configuration
Kits are built in batches, one configuration at a time, from the build sheet.
Step 4
Kit barcode applied and verified
The kit's own barcode is applied and read back by scanner before the unit is packed.
Step 5
Poly bag or shrink wrap
Kits are poly bagged or shrink wrapped as the listing requires. A suffocation warning goes on the bag when Amazon requires one.
Step 6
Boxed, with box content sent by API
Finished kits are packed by SKU and the box content goes to Amazon through our own SP-API integration. Freight goes on Amazon's partnered carrier when Amazon offers it.
Bagging and wrapping: Poly bagging and shrink wrapping · Something outside the build sheet: Custom prep · Kits that come back or change: Unbundling and kit rework
