Platform

Everything a prep center needs.

Inbound receiving, prep tracking, FBA shipment creation, itemized billing, and a branded seller portal — in one platform built end to end for Amazon FBA prep operators.

What you get

Every part of the prep workflow, in one app

Every capability below is included on every plan. See Pricing for plan tiers based on monthly volume.

Inbound

Inbound receiving workflow

Log parcel and pallet inbound, capture photo evidence on arrival, and tie every box to a seller PO so nothing gets lost between dock and prep floor.

  • Parcel and LTL pallet receiving
  • Photo evidence on every inbound
  • PO reconciliation against the seller
Inbound

Container destuffing tracking

Schedule, log, and bill direct-to-warehouse 20 ft and 40 ft container unloads. Tie every container to the inbound shipments it produces.

  • 20 ft and 40 ft containers
  • Tied to inbound shipments
  • Auto-billed to the seller
Prep

Prep tracking

Move every unit through FNSKU labeling, polybag, bundle, fragile, and oversize prep with a full audit history. Add prep types per SKU or per shipment.

  • Full audit history per unit
  • Per-SKU prep instructions
  • Operator throughput visibility
Prep

Add-on services & extras

Define your own prep extras — polybag, bubble, multipack, bundle, OA / RA handling, oversize — and have them attach to the seller invoice automatically.

  • Configurable per prep center
  • Per-unit or per-shipment
  • Auto-billed at invoice time
Outbound

FBA shipment creation (SP-API)

Build, label, and book FBA shipments directly through Amazon SP-API. STA / SPD partnered carriers, multi-destination splits, and 2D box content barcodes — all in the platform.

  • SP-API shipment plans
  • Partnered carrier (UPS) booking
  • Amazon US and Amazon Canada marketplaces
Billing

Itemized per-unit billing

Configure your prep tiers, add-ons, and receiving fees once. Stratosphere generates the per-unit invoice for every seller and collects via Stripe.

  • Configurable rate cards
  • Stripe payments built in
  • Downloadable PDF invoices for sellers
Billing

Storage & receiving fees

Track included storage windows, post-window pallet storage rates, container destuffing, and additional labour — billed alongside prep on a single invoice.

  • Included storage windows
  • Pallet / month rates
  • Labour and destuff line items
Sellers

Seller portal

Every prep center gets a branded seller portal where its sellers see live inbound, prep status, FBA shipments, photo evidence, and downloadable invoices.

  • Live status per shipment
  • Photo evidence visible to seller
  • Self-serve invoice downloads
Operations

Exception tracking

Flag missing labels, damaged goods, prep blockers, and shipment issues while the work is happening so the owner and seller both know what needs attention.

  • Prep blockers visible early
  • Seller-facing notes
  • Photo evidence attached to the issue
Operations

Operations dashboard

Throughput, backlog, and shipment status across the entire prep floor — so the operator knows what's stuck before the seller emails to ask.

  • Backlog and aging views
  • Per-operator throughput
  • Shipment status at a glance
