Clear answers for Amazon FBA sellers.
Running Amazon FBA at scale comes with a lot of moving parts. This page gives you straight answers to the questions sellers ask most often before partnering with Fast Prep UK.
Ask us on WhatsAppGetting started with Fast Prep UK
How onboarding, supplier deliveries and your FastPrep OS account work.
Yes. You can use our warehouse as the shipping / delivery address for your suppliers. Your registered company address and billing address stay the same (usually your accountant or office). Only the delivery address on the PO and shipping label changes to our warehouse.
We recommend that every shipment to us clearly shows:
- Your company name / Amazon store name
- A reference (PO number or shipment name)
- Our full warehouse address (copy it from your account in one click)
This way, when a lorry arrives with multiple loads, we can quickly match your cartons to your account — and you see them as received in your FastPrep OS account.
No long-term contract and no rigid minimum to start. You can work with us whether you're testing your first shipments or already sending thousands of units per month. We do not lock you into 6–12 month agreements and we do not charge onboarding or setup fees.
What we do ask for during onboarding:
- Your estimated monthly volume band (0–100, 101–500, 501–1,000, 1,001–2,000 or 2,000+ units)
- The types of products you sell (categories, fragility, special handling)
This helps us plan capacity and give you realistic expectations on processing times as you scale.
Getting started is simple:
- Open your account online with your contact and business details — it takes about 2 minutes.
- Confirm our terms in your FastPrep OS account — your prices, our address and everything you need are already there.
- Connect your Amazon account from the app in a few clicks, through Amazon's own secure authorisation (for shipping plans and labels).
- Start shipping! Announce the delivery in your account and send your goods directly from your suppliers to our warehouse.
You don't have to email us every time you send stock. Here's how it works:
- You announce the delivery in your account (Deliveries to FastPrep): the products, the quantities and the tracking number
- Our team is notified automatically the moment you save it
- We get ready to receive and prep those products, and you follow every box in your account
Add the courier's tracking number to the delivery. Our system follows the parcel at the courier automatically, so we know exactly when it arrives. When it reaches us we scan it at the door, and it shows as received in your account.
Storage, product limits & risk management
What we store, for how long, and which products sit outside our standard service.
Yes. Storage is charged per cubic metre, for every night your goods are with us, from the day they arrive, at the rate on your My rates page.
No storage fee:
- The goods arrive for a prep request you created before they arrived
- They are waiting only for our team to prep them and send them to Amazon
Storage fee applies:
- The goods arrive and no request is ready yet to send them to Amazon
- They wait for something on your side — a listing to fix, a label, a decision
- You keep stock with us on purpose and send it to Amazon over time
Yes. To keep operations safe, predictable and cost-effective, we work within a few clear limits under our standard service:
- Maximum purchase value: up to ~£100 per unit (your buy price from the distributor / manufacturer). This limits financial risk if compensation is needed in rare cases of damage or loss.
- Maximum dimension: up to ~100 cm on the largest side. Oversized goods create handling and safety constraints that slow operations and increase costs.
Items that fall outside these limits — for example very high-value units, very large or heavy items, or temperature-sensitive products — are reviewed case by case. Where possible, we'll confirm feasibility and pricing before accepting them into the warehouse.
Operations, prep & shipping to Amazon FBA
Turnaround times, shipping plans, removals, returns and multi-channel support.
Our standard target is around 24 hours for regular FBA prep shipments once the goods are fully received and all instructions are clear.
Larger volumes (full containers, big pallet projects) or custom prep may take longer, but we agree the timeline with you in advance. In all cases, you can see the live status of each SKU and shipment in your FastPrep OS account.
We can work in both ways:
Full-service mode (standard and preferred):
- We create the Amazon FBA shipping plans in your Seller Central
- We generate FNSKU labels and box / pallet labels
- We prepare cartons / pallets and book carriers
You create the shipping plans, we follow your labels:
- You create the shipments in Seller Central
- You send us the FNSKU labels and box labels
- We apply them and dispatch according to your plan
Yes — it's a standard service at Fast Prep UK. We manage:
- Amazon removal orders delivered to our warehouse
- Customer returns you want us to inspect, rework, and prep back into FBA (or route elsewhere)
Typical steps can include: receiving and logging returned units, visual inspection (and basic checks where possible), sorting resellable vs non-resellable stock, repacking and re-labelling resellable units for FBA, and preparing unsellable stock for supplier return, disposal, or your preferred action.
Pricing: in most cases, removals and returns are charged using our standard pricing — verify in the Pricing Calculator. Exceptions: only unusual cases (complex testing, heavy rework, mixed conditions, non-standard workflows) are quoted separately based on actual time and complexity.
Our core business is Amazon FBA prep and inbound handling. We're not a D2C pick-and-pack fulfilment centre for individual Shopify or eBay orders. However:
- We can receive and store inventory that you later send to another fulfilment partner
- We can forward bulk stock (cartons or pallets) to other warehouses, distributors or partners
If you have a more complex, multi-channel setup and want to see whether we can support part of it, send us the details and we'll let you know what's feasible.
Pricing, billing & contracts
Fees, calculator, invoicing cycle and how we keep pricing transparent.
No. We keep pricing simple and transparent:
- No onboarding / setup fees
- No monthly subscription
- No "account admin" charges
- No surprise receiving fees added at the end
Every chargeable operation (receiving, labelling, polybagging, bundling, pallet prep, storage, etc.) is listed clearly in our FBA Prep Cost Calculator, explained in plain English on our Services page, and recorded in your FastPrep OS account as we work.
We use a per-operation, per-unit model — what we call the Profit-Grid.
Use the online FBA Prep Calculator:
- Select your monthly volume band
- Add the services you typically need (receiving, FNSKU labelling, polybagging, bundling, pallets, storage, etc.)
- See your effective cost per unit and per batch before you ship
Track everything in your FastPrep OS account: every time we perform an operation, it's logged against the relevant SKU or shipment. You can see running totals and status in real time — no waiting for the invoice to know where your money went.
This gives you exact landed prep cost per SKU, so you can set safe repricer floors, identify high-cost low-margin SKUs, and make pricing and sourcing decisions based on real numbers, not averages.
We invoice once per month:
- Invoice is issued on the 1st of each month
- It covers all work completed in the previous month
- You have 7 days to settle the invoice
Your FastPrep OS account
The platform you share with our warehouse — what it does, who can use it and how your data stays safe.
FastPrep OS is our own platform — the same system our warehouse team works in every day. In your account you announce deliveries, see every box we receive, ask us to prep and send goods to Amazon, and follow your costs and invoices. Everything you see is live, straight from the warehouse floor.
Yes. You connect it from your FastPrep OS account through Amazon's own authorisation, and you can disconnect it at any time. We only use what prep needs: your products, shipping plans, labels and shipment status. We never see your card, bank or payout details.
Yes. In Team you add colleagues, a VA or your bookkeeper, each with their own login and the right access — for example Operations for requests, Finance for billing, or Viewer to only look.
Yes. The assistant in your account answers questions about your stock, your requests and your costs at any time, using your own live data. For anything else, message our team from the app, on WhatsApp or by email.
Yes. With the FastPrep OS API your systems can announce deliveries, create prep requests and read your stock, boxes and decisions automatically. Webhooks tell your system the moment something changes.
From now on everything happens in your FastPrep OS account: announcing deliveries, prep requests, status and costs. Your spreadsheet stays as a read-only archive of everything before. We send each client a personal link to open the account with the details we already have.
