Understanding FBA prep costs in the UK
Whether you self-prep at home or outsource to a professional prep centre, getting your inventory ready for FBA comes with a cost either way. Amazon's fulfilment standards are strict, stock needs inspecting, FNSKU labelling, poly bagging, and boxing to a specific standard, and getting it wrong risks a rejected shipment. This guide breaks down what you're actually paying for, the different pricing models used across the industry, and the hidden costs worth watching for.
What's included in FBA prep pricing?
Core prep services
- ◆Stock receiving & logging — your shipment is logged in and quantities verified against what was expected.
- ◆Inspection — each item checked for visible damage, defects, or discrepancies.
- ◆FNSKU labelling — your unique Amazon barcode printed and applied to every unit.
- ◆Poly bagging — protective plastic wrapping where the category requires it.
- ◆Boxing — units packed into Amazon-standard boxes, reusing your incoming packaging where possible.
- ◆Shipping to Amazon — delivery to the fulfilment centre, included in the per-unit price at Precision.
Optional / premium services
- ◆Bundling / kitting — combining multiple products into a single sellable unit, priced higher than standard prep due to the extra handling.
- ◆Oversized item prep — large or heavy items requiring different handling.
- ◆Dangerous goods processing — items like batteries or flammables requiring specialist handling and documentation.
- ◆Storage — holding stock before it's sent to Amazon, typically charged by the week or month.
FBA prep pricing models
| Model | How it works | Trade-off |
|---|---|---|
| Per-unit pricing | A fixed fee for each item prepped, the most common approach across UK prep centres. | Transparent and predictable, but costs scale directly with volume and complexity. |
| Tiered / volume pricing | Discounted rates once you cross a volume threshold. | Rewards scale, but you need to actually hit the threshold to benefit. |
| Flat-rate pricing | A fixed fee per shipment rather than per unit. | Can work for very small shipments, less cost-effective at larger volumes. |
| Hybrid pricing | A combination of per-unit and per-shipment charges. | Covers a centre's fixed overhead, but means calculating your true all-in cost rather than reading the headline rate alone. |
What affects FBA prep pricing?
- ◆Product complexity — simple, single-SKU items cost less than bundles, oversized products, or dangerous goods.
- ◆Shipment volume — larger shipments often qualify for volume discounts as the centre gains operational efficiency.
- ◆Turnaround requirements — rush processing outside the standard timeline typically carries a premium, worth clarifying upfront with any provider.
- ◆Specialised requirements — dangerous goods, custom labelling, or photo documentation all add cost.
- ◆Warehouse location — a centrally located UK prep centre can mean lower onward shipping costs to multiple fulfilment centres.
- ◆Frequency & loyalty — regular, high-volume clients can sometimes negotiate better rates than one-off shipments.
Hidden costs to watch out for
- ◆Box costs — charged if new boxes are needed because incoming packaging is damaged or unusable, always ask whether a centre reuses your boxes where possible.
- ◆Storage fees — if stock arrives before you're ready to ship it on to Amazon.
- ◆Receiving / check-in fees — some centres charge separately for logging stock in on top of the prep fee, always clarify what's included.
- ◆Shipping not included — some providers quote only the prep fee and charge shipping to Amazon separately.
- ◆Minimum order fees — a flat minimum charge regardless of shipment size.
- ◆Returns / rework fees — if Amazon rejects part of a shipment and it needs reworking.
- ◆VAT & payment surcharges — UK prices are usually quoted excluding VAT, and some providers add surcharges for certain payment methods.
How Precision's pricing works
Our pricing is built to be transparent and competitive, with no hidden costs:
| Service | Price | What's included |
|---|---|---|
| Standard prep | 45p per unit | Receiving, inspection, FNSKU labelling, poly bagging, boxing, and shipping to Amazon |
| Bundling | 80p per bundle | Assembly, “Sold as Set” labels, FNSKU, poly-wrapping, boxing, and shipping |
| Oversized items | 85p per unit | All standard services, sized for large or heavy items |
| Dangerous goods | £2 flat fee per shipment | Specialist handling, labelling, and documentation |
| Volume discount (1,500+ units) | 5% off | Applied to the standard prep rate |
| Volume discount (2,500+ units) | 10% off | Applied to the standard prep rate |
| New boxes (if needed) | £2 per box | We reuse your incoming boxes wherever possible |
- ◆No hidden fees — receiving, inspection, labelling, and shipping to Amazon are all included in the per-unit price.
- ◆Delivery to Amazon included — we don't charge separately for shipping your prepared stock on to fulfilment centres.
- ◆Box reuse — we reuse your incoming boxes wherever possible to keep costs down, only charging for new boxes when genuinely needed.
- ◆No minimum order — the same per-unit rate applies whether you're sending 100 units or 10,000, subject to volume discounts.
Calculating your total prep cost
Total prep cost = (units × per-unit price) + box costs + storage (if applicable) + any premium services.
Example: 1,000 standard units at 45p per unit, plus 2 new boxes at £2 each = (1,000 × £0.45) + (2 × £2) = £450 + £4 = £454 total, or roughly 45.4p per unit.
With a volume discount: 2,500 units at the 10% discounted rate = 2,500 × £0.45 × 0.9 = £1,012.50, or roughly 40.5p per unit.
Is using a prep centre worth the cost?
Time
DIY prep requires real labour hours, and those are hours you're not spending sourcing products, optimising listings, or running ads. For a growing business, that opportunity cost adds up quickly.
Compliance risk
A single mislabelled box or missing FNSKU can get an entire shipment rejected, costing days of delay and the expense of rushed re-prepping. A prep centre that does this daily knows exactly what Amazon expects.
The real ROI
At 45p per unit, prepping 1,000 units costs £450. Doing it yourself takes real hours of labour, once you value your own time realistically, a prep centre is very often the cheaper option, and the gap widens further as volume scales.
For sellers sending meaningful volume each month, outsourcing to a prep centre tends to pay for itself in time saved and mistakes avoided, though the exact break-even point depends on how you value your own time.
