Monthly volume sets your per-unit rate tier — the biggest cost lever.

Over ~20 lb or 18 inches.

Fragile or glass items.

Multipacks and kitted sets, billed per bundle.

Estimated monthly prep cost (low – high)

$980 – $1,790

Blended per unit: $0.98 – $1.79

Standard prep — 500–2,499 units/mo$750 – $1,250
Oversize / heavy surcharge$50 – $200
Receiving$20 – $140
Storage$160 – $200

DIY comparison: prepping in-house typically runs $1,200 – $1,800/month at this volume ($1.20–$1.80/unit in labor + materials).

Why prep matters: Amazon ended its own FBA prep service on January 1, 2026. Unprepped shipments lose damage-reimbursement eligibility, and the ~$0.60/unit inbound defect fee would be roughly $600/month on this volume.

Based on published US prep-center rates, July 2026. Standard prep assumes FNSKU labeling and polybagging are included; some providers itemize them. Real quotes vary with product mix and region.

What Changed in January 2026

For years, sellers could send unlabeled, unbagged product to Amazon and pay a per-unit fee for Amazon to prep it at the fulfillment center. That service ended in the US on January 1, 2026. Every shipment created since must arrive with FNSKU labels applied, polybags with suffocation warnings where required, and packaging that meets Amazon's prep rules for the product category.

The enforcement teeth are real: unprepped shipments no longer qualify for damage reimbursement, and Amazon's inbound defect fee runs about $0.60 per unit on non-compliant shipments. On a 2,000-unit shipment that is $1,200 of pure penalty. Amazon's official guidance now points sellers to exactly two options: prep in-house, or hire a third-party prep provider — which is why prep-center demand jumped in 2026.

Compare all-in cost, not headline rate. A $0.50-per-unit headline can cost more than a $0.90 all-inclusive rate once labeling, bagging, receiving, and storage are itemized on top. Ask what the base rate includes, whether there is a setup fee ($0–$2,000 across the market, often waived), and whether a monthly minimum applies (300+ units at some providers, none at others).

Prep Center vs. DIY: Where the Break-Even Sits

DIY prep costs roughly $1.20–$1.80 per unit all-in: materials are only $0.05–$0.15, but a practiced person preps 40–80 simple units an hour, and most sellers are not practiced. Three volume bands tell the story:

  1. Under ~500 units/month. DIY and outsourced prep cost about the same on paper — the decision is about your time and error rate. Many prep centers now run no-minimum pricing aimed at exactly this tier.
  2. 500–2,500 units/month. Volume-tiered prep rates ($0.75–$1.25/unit) usually undercut in-house labor, and the 15–25 hours a month of prep work is better spent on sourcing and listings.
  3. 2,500+ units/month. Published rates of $0.40–$0.75 per unit are well below realistic DIY costs, which now require dedicated staff and space. This tier is not close.

Two product profiles push toward a prep center even at low volume: oversize or heavy goods (DIY prep of 40-pound items is slow and miserable, and many prep centers refuse them — the ones that accept them are built for it), and imported container freight, where prepping at the port eliminates a freight leg that dwarfs the prep fees.
