PrepVia vs DIY FBA Prep: The Real Cost of Doing It Yourself

Most sellers underestimate the true cost of in-house prep by 3–4x

FBA prep center vs DIY · Outsource FBA prep · Cost comparison

With Amazon ending its FBA Prep Service, every seller now faces the same decision: build an in-house prep operation or outsource to a prep center. DIY sounds cheaper on paper, but when you add up warehouse rent, labor, equipment, supplies, and the opportunity cost of your time, most sellers discover they're spending $15,000 to $20,000 per month to do what a prep center handles for a fraction of that cost. Here's how the numbers actually break down.

Honest Assessment

Which Approach Is Right for You?

We believe in transparency. DIY prep works for some sellers. Outsourcing works for most. Here's how to decide.

When DIY Makes Sense

  • You ship fewer than 200 units per month
  • You enjoy hands-on work and have time to spare
  • You already have free warehouse space
  • You’re not time-sensitive about Amazon check-in speed

When Outsourcing Makes Sense

  • You ship over 500 units per month
  • Growth is a higher priority than control
  • You value speed and accuracy over doing it yourself
  • You don’t want warehouse overhead and staff management
  • You need Net-30 cash flow flexibility
Real Scenarios

The Switching Moment

These are the moments when sellers realize it's time to outsource FBA prep.

“I spent 3 weekends in a row labeling 4,000 units instead of sourcing new products.”

“My DIY prep took 10 days. By the time inventory went live, I’d already missed the demand spike.”

“Amazon rejected my shipment because of label placement errors. I had to re-prep 2,000 units.”

“When I added up rent, labor, and supplies, I was spending $18K/month to prep what PrepVia does for $5K.”

DIY vs Outsourced FBA Prep — Common Questions

Is it cheaper to prep FBA inventory yourself or use a prep service?

When you account for all costs — warehouse rent, labor, utilities, insurance, supplies, and the opportunity cost of your time — DIY prep typically runs $15,000 to $20,000 per month for a mid-volume seller processing around 10,000 units. PrepVia handles the same volume for approximately $5,000 per month with everything included: prep, labeling, shipping to Amazon, and real-time tracking. Most sellers underestimate DIY costs by 3 to 4 times because they only count supplies and rent.

How much time does DIY FBA prep actually take?

For a 10,000-unit shipment, manual prep typically takes 7 to 10 working days including receiving, inspection, labeling (at 500–1,000 units per hour by hand), packing, and shipment creation. That does not include the time spent managing the warehouse, ordering supplies, and handling errors. PrepVia completes the same volume in 24 to 36 hours with automated workflows.

What equipment do I need for in-house FBA prep?

A basic in-house FBA prep setup requires: a thermal label printer ($300–$500), poly bag sealer ($200–$500), shrink wrap machine ($500–$2,000), packing tape dispensers, shelving and racking ($1,000–$5,000), a computer and barcode scanner ($500–$1,000), plus ongoing supplies like FNSKU labels, poly bags, boxes, and packing materials. Total initial equipment investment is typically $15,000 to $25,000, not including the warehouse lease.

At what volume should I switch from DIY to a prep center?

Most sellers find the breakeven point is around 300 to 500 units per month. Below 200 units, DIY can be cost-effective if you have free space. Above 500 units, the time you spend prepping is almost always worth more than the cost of outsourcing. The real tipping point is when prep time starts cutting into sourcing, marketing, or product research — the activities that actually grow revenue.

How do I transition from DIY prep to PrepVia?

Transitioning is straightforward. Sign up on the PrepVia App, connect your Amazon Seller Central account via API, and ship your next batch of inventory to our Miami, FL warehouse instead of your own space. We handle receiving, inspection, labeling, and shipping to Amazon. Most sellers transition in a single shipment cycle with zero downtime. You can phase the transition by sending some shipments to PrepVia while winding down your own prep operation.

What if I want to do some prep myself and outsource the rest?

Many sellers use a hybrid approach, especially during the transition period. You might prep small, simple shipments yourself and send larger or more complex shipments (bundling, kitting, oversize) to PrepVia. There are no volume minimums or long-term contracts, so you can use PrepVia for one shipment or all of them. The flexibility of Net-30 payment terms also means you are not locked into prepaying for services you may not need every month.

Does PrepVia handle all the same prep types I do in-house?

Yes. PrepVia covers FNSKU labeling, poly bagging, shrink wrapping, bubble wrapping, bundling and kitting (2 to 24+ units per pack), shipment creation via Amazon API, storage, and FTL/LTL forwarding. We also handle inspection, discrepancy reporting, and oversize items. If you are currently doing it in your warehouse, PrepVia can do it faster with 99.9% accuracy.

How fast can I get started?

Same-day onboarding. Sign up on the PrepVia app, create your first shipment, and start sending inventory — all in the same day. No setup fees, no minimums, no waiting period.
