🏭 Prep Centres vs Self-Ship

When you buy products to sell on Amazon FBA, they need to be prepped before they can be sent to Amazon’s warehouse. This means labelling, packaging, and sometimes bundling your items so they meet Amazon’s requirements.

You’ve got two options: do it yourself at home, or pay a prep centre to handle it for you.

What Does “Prepping” Involve?

• FNSKU labelling — sticking Amazon’s barcode label on each unit
• Poly bagging — putting products in clear bags with suffocation warnings where required
• Bubble wrapping — protecting fragile items
• Bundling — combining multi-packs if you’re selling bundles
• Box packing — packing items into boxes that meet Amazon’s weight and dimension requirements
• Creating the shipment — generating labels and booking delivery to Amazon

Option 1: Prepping at Home (Self-Ship)

What You Need

• A printer (for FNSKU labels and box labels)
• FNSKU label stickers (blank labels from Amazon or eBay, ~£10 for 1,000)
• Poly bags with suffocation warnings (various sizes, ~£5-15)
• Bubble wrap (for fragile items)
• Packing tape and sturdy boxes
• A decent workspace — a table or desk is fine to start with

Pros

• Free — no per-item fees
• Full control — you see every product and can check quality yourself
• Faster turnaround — you can prep and ship the same day you receive stock
• You learn the process — understanding prep makes you a better seller even if you outsource later

Cons

• Takes time — labelling 50 units takes a solid chunk of your evening
• Space — boxes pile up quickly, especially if you’re scaling
• Doesn’t scale — at some point, your living room can’t be a warehouse anymore
• Boring — let’s be honest, it’s not the exciting part of the business

When Self-Ship Makes Sense

• You’re doing under 50-100 units per week
• You’re just starting out and want to learn the full process
• Your margins are tight and you can’t afford prep centre fees
• You’ve got the space at home

Option 2: Using a Prep Centre

A prep centre is a third-party warehouse that receives your stock, preps it to Amazon’s standards, and ships it into FBA on your behalf.

How It Works

1. You buy products online and have them delivered directly to the prep centre (not your home)
2. The prep centre receives and logs your stock
3. They label, poly bag, bubble wrap, and pack everything
4. They create the shipment in Seller Central (or you do it remotely)
5. They send it to Amazon’s warehouse

You never touch the product. It goes from retailer → prep centre → Amazon → customer.

What It Costs

Prep centre pricing varies, but typical UK rates:

Rough rule of thumb: Budget around £1-2 per unit all-in for a standard prep centre service. Factor this into your profit calculations BEFORE buying stock.

Pros

• Saves huge amounts of time — you focus on sourcing, they handle the rest
• Scales easily — whether you’re doing 50 or 500 units a week
• No space needed — your home stays a home, not a warehouse
• Professional quality — less chance of prep errors that get your shipment rejected

Cons

• Costs money — £1-2 per unit adds up, especially on low-margin products
• Less control — you’re trusting someone else to check quality
• Turnaround time — most prep centres take 1-3 days to process your stock
• Communication — good prep centres are responsive, bad ones cost you money through delays

When a Prep Centre Makes Sense

• You’re doing 50+ units per week regularly
• You value your time more than the per-unit cost
• You don’t have space at home
• You want to scale the business properly

How to Choose a Good Prep Centre

Not all prep centres are equal. Here’s what to look for:

1. Turnaround time — ideally 1-2 working days
2. Transparent pricing — no hidden fees, clear per-unit costs
3. Good communication — they respond to emails/messages quickly
4. Photos of your stock — some will send photos so you can check condition
5. Reviews/recommendations — ask in the Money Masters community for recs
6. Location — closer to Amazon’s UK warehouses can mean lower shipping costs

Pro tip: Start prepping at home so you understand exactly what’s involved. Once you’re consistent and doing enough volume, switch to a prep centre. You’ll be able to spot if they’re doing a bad job because you’ve done it yourself.

The Hybrid Approach

Many sellers use a mix:

• High-value or complex products → prep at home so you can check quality
• Standard, simple products → send straight to the prep centre
• Bulk wholesale orders → prep centre (you don’t want 500 units in your living room)

There’s no right or wrong answer. It depends on your volume, your margins, and how much you value your time. Start at home, move to a prep centre when it makes sense financially.
