Introduction: Understanding FBA Prep Costs in the UK
If you're selling on Amazon UK through FBA, getting your products prepared correctly is crucial — but it comes with a cost. Whether you're self-prepping at home or outsourcing to a professional prep centre, understanding the pricing landscape will help you make better business decisions.
Amazon's fulfilment standards are strict. Your inventory needs to be inspected, labelled with FNSKUs, polybaged, and boxed in very specific ways. Miss these details, and Amazon will reject your entire shipment, costing you time and money. This is why many sellers choose to use a UK-based prep centre like Precision — not just to save time, but to ensure compliance from day one.
In this guide, we'll break down exactly how much FBA prep costs, what you're paying for, the different pricing models used across the industry, and what hidden costs you need to watch out for.
What's Included in FBA Prep Pricing?
When a prep centre quotes you a price per unit, different services are included depending on the centre and the pricing tier. Here's what typically falls under "standard FBA prep":
Core Prep Services
- Stock Receiving & Logging: Your shipment arrives at the warehouse and is logged into the system. Quantities are verified against what was expected.
- Inspection: Each item is checked for visible damage, defects, missing components, and discrepancies. This protects your account and your customers.
- FNSKU Labelling: Your unique Amazon barcodes are printed and applied to each unit. This is non-negotiable for FBA compliance.
- Polybaging: Items are placed in polybags (plastic wrapping) to protect them during storage and shipping — especially important for items that could be damaged by dust or moisture.
- Boxing: Units are packed into Amazon-standard boxes, ready for shipment to fulfilment centres. The prep centre uses new boxes or reuses your incoming packaging where possible.
- Shipping to Amazon: The prepared inventory is picked up and delivered to Amazon's fulfilment centres. Most quality prep centres include this in the per-unit price.
Pricing varies across UK prep centres depending on the provider and the complexity of your products. At Precision, standard prep is 45p per unit all-in.
Optional / Premium Services
- Bundling / Kitting: Combining multiple products into a single unit (multi-packs, gift sets, variety packs). Costs more per unit due to extra handling. At Precision, bundling is 80p per unit.
- Oversized Item Prep: Large or heavy items require different handling and cost more. At Precision, oversized items are 85p per unit.
- Dangerous Goods Processing: Items classified as hazardous (batteries, flammable, etc.) require special handling and labelling. Costs vary by centre.
- Storage: Holding your stock before it's sent to Amazon. Typically charged by the week or month, depending on volume.
- Photo Documentation: Professional photos of your products for quality assurance or record-keeping. Some centres charge extra for this; others include it.
- Returns Processing: Handling products that Amazon returns for being non-compliant or overstocked. Varies by centre.
FBA Prep Centre Pricing Models
There's no one-size-fits-all pricing model in the prep centre industry. Understanding the different approaches will help you compare quotes fairly.
Per-Unit Pricing (Most Common)
The vast majority of UK prep centres use per-unit pricing. You pay a fixed fee for each item prepared, regardless of product type (with exceptions for oversized or bundled items).
UK Per-Unit Rates Vary by Centre:
Standard prep: pricing varies by provider
Bundling: pricing varies by provider
Oversized: pricing varies by provider
Advantage: Transparent and predictable. You know exactly what you'll pay before you ship.
Disadvantage: If you have complex items or high volumes, the total cost can add up quickly.
Tiered / Volume Pricing
Many prep centres offer discounts when you send larger shipments.
Advantage: Rewards sellers who scale. Larger volumes typically qualify for better rates than smaller shipments.
Disadvantage: You need to reach the threshold to benefit. It may also incentivise over-ordering to hit a discount tier.
Flat-Rate Pricing
Some prep centres (usually smaller operations or for specific services) charge a flat fee per shipment rather than per unit, plus the cost of boxes.
Advantage: Can work well for small shipments.
Disadvantage: Becomes less cost-effective for larger volumes, so the effective per-unit cost varies with order size.
Hybrid Pricing
Some centres combine per-unit and per-shipment charges.
Advantage: Centres can cover their fixed overhead costs while offering competitive per-unit rates.
Disadvantage: You need to calculate the true all-in cost rather than just looking at the per-unit price alone.
What Affects FBA Prep Pricing?
Several factors determine where on the pricing spectrum your prep costs will fall:
Product Complexity
Simple items (single SKU, standard size, no bundling) cost less to prep. Complex items (variants, bundles, oversized, dangerous goods) cost more. At Precision, standard prep is 45p per unit, bundling is 80p, and oversized items are 85p — reflecting the extra handling involved.
Shipment Volume
Larger shipments often qualify for volume discounts. Prep centres save money per unit through operational efficiency at higher volumes and pass some of that saving on to you. Always ask about volume pricing tiers.
Turnaround Time Required
Most prep centres offer standard turnaround at no extra cost. If you need rush processing, expect to pay a premium, so clarify timelines and costs upfront.
Specialised Requirements
Anything outside standard prep carries extra cost: dangerous goods, poly-mailers, custom labelling, photo documentation, bundle assembly, and so on. These vary by centre.
Warehouse Location
Prep centres located closer to major Amazon fulfilment centres often charge slightly less because they save on shipping costs. A prep centre in the Midlands (like Precision in Atherstone) might be cheaper than one in the far north or south due to proximity to multiple FCs.
Frequency & Loyalty
Some prep centres offer loyalty discounts to regular clients. If you're sending shipments every week, you might negotiate a better per-unit rate than a one-off customer.
Hidden Costs to Watch Out For
When comparing prep centres, don't just look at the per-unit price. Several "hidden" costs can significantly increase your total expense:
Box Costs
If you're not providing your own boxes, or if the prep centre needs new boxes (because your incoming packaging is damaged), you'll be charged. Box costs vary by centre.
Storage Fees
If your stock arrives before you're ready to ship it to Amazon (waiting for a shipping plan approval, managing stock levels, etc.), you'll pay storage. Rates vary by centre and volume, so storage costs can add up depending on your needs.
Receiving / Check-In Fees
Some prep centres charge a separate fee just to receive and log your stock, on top of the prep fee. Always clarify whether "receiving" is included in the quoted per-unit price or charged separately.
Shipping Costs Not Included
Watch out for prep centres that quote only the prep fee but don't include shipping to Amazon. If you have to arrange and pay for shipping separately, costs can vary significantly depending on the shipment size and distance.
Minimum Order Fees
Some centres impose a minimum charge per shipment. Always check whether you'll incur extra costs if your shipments are small.
Returns / Rework Fees
If Amazon rejects part of your shipment (non-compliance, damage, etc.) and the prep centre has to rework or return the items, will you be charged? Some centres include this in their service; others charge extra.
VAT & Payment Method Surcharges
All UK prices are typically quoted excluding VAT (which you can usually reclaim as a VAT-registered seller). Some centres charge surcharges for certain payment methods, so ask about payment options upfront.

Key Pricing Features
- No Hidden Fees: What you see is what you pay. Receiving, inspection, labelling, and shipping to Amazon are all included in the per-unit price.

- Box Reuse: We reuse your incoming boxes whenever possible, keeping your costs down. We only charge £2 per new box if necessary.
- No Minimum Order: Whether you're sending 100 units or 10,000, we prep them for the same per-unit rate (subject to volume discounts).
- Transparent Volume Discounts: Hit 1,500 units and you get 5% off. Hit 2,500 units and you get 10% off. The tiers are clear upfront.
- Fast Turnaround: Standard prep is 24 hours from arrival. Larger shipments (2,500+ units) may take up to 48 hours, but there's no rush fee.
Calculating Your Total Prep Cost
To work out your exact FBA prep investment, use this formula:
Total Prep Cost = (Units × Per-Unit Price) + Box Costs + Storage (if applicable) + Any Premium Services
Example: 1,000 standard units at 45p per unit, with 2 new boxes at £2 each = (1,000 × £0.45) + (2 × £2) = £450 + £4 = £454 total
Cost per unit = £454 ÷ 1,000 = 45.4p
If you cross into a volume discount tier, recalculate:
Example with Volume Discount
If you hit 2,500 units at Precision: (2,500 × £0.45 × 0.9) = (2,500 × £0.405) = £1,012.50
Cost per unit = £1,012.50 ÷ 2,500 = 40.5p
Is Using a Prep Centre Worth the Cost?
Many sellers ask: could I just do this myself and save the money? The short answer is yes, but you'll probably lose money overall. Here's why:
Time Cost
DIY prep requires significant labour hours. When you factor in your hourly rate, the labour cost becomes substantial. More importantly, those hours are hours you're not sourcing products, optimising listings, or running ads. For a scaling business, that opportunity cost is huge.
Compliance Risk
Amazon is strict about prep standards. A single mislabelled box or missing FNSKU can cause your entire shipment to be rejected, costing you 5–10 days and hundreds of pounds in rush re-prepping. Professional prep centres know exactly what Amazon expects and get it right the first time.
Quality & Speed
Professional prep centres process shipments in 24–48 hours. Self-prepping often takes a week or more, meaning your stock reaches Amazon slower and you miss sales in that window.
The Real ROI
At 45p per unit (Precision's rate), prepping 1,000 units costs £450. Doing it yourself "costs" you 25+ hours of time. If you value your time at £20/hour, that's £500 in labour. The prep centre is cheaper, faster, and compliant. And as you scale to 5,000+ units per month, the savings (in time and accuracy) become even more obvious.

Summary: FBA Prep Costs in the UK
FBA prep costs in the UK typically range from 40p to 80p per unit for standard preparation, depending on the prep centre, your volume, and product complexity. The most transparent, cost-effective approach is to:
- Choose a prep centre with clear, per-unit pricing and no hidden fees.
- Ask exactly what's included (receiving, inspection, labelling, polybaging, boxing, shipping).
- Watch out for extra charges (boxes, storage, minimums, returns rework).
- Calculate your all-in cost, including any volume discounts.
- Compare the cost of outsourcing against the time you'd spend self-prepping.
- Choose quality over the cheapest quote — Amazon rejections and compliance issues will cost you far more than you save on prep fees.
