Own warehouse or fulfillment partner: when does outsourcing pay off?

Dávid Kornis, Head of Fulfillment Division · Published: November 10, 2026 · 6 min read

In short
  1. Running your own warehouse costs more than the rent: staff, cover, packaging materials, carrier contracts, software, and your own time.
  2. Outsourcing makes sense when packing starts taking time away from growth, or when you also sell on a second channel (marketplace, B2B).
  3. When choosing a partner, look at the dispatch cut-off, itemized pricing and how fast returns are processed first.

Most online stores start packing orders at home or in a small storeroom. For a while, that's the cheapest option. Then comes the point where packing takes more time than buying or selling. This article helps you recognize where you are, and what to look for if you decide to outsource.

What does your own warehouse really cost?

Most people equate the cost of their own warehouse with the rent. The full picture is wider:

  • Space: rent, utilities, shelving. Too little at peak times, partly empty the rest of the year.
  • Staff: packers' wages, plus cover during holidays or sick leave.
  • Packaging materials: boxes, void fill, tape. More expensive in small quantities than in bulk.
  • Carrier fees: with low volumes, it's harder to get a good carrier contract, and every carrier has to be managed separately.
  • Software: inventory management, label printing, connecting your online store and marketplaces.
  • Your time: every hour you spend packing or reconciling stock is an hour taken from growth.

Add these up for one month and divide by your monthly order count. That's your own cost per order, the figure to compare a fulfillment partner's quote against.

Six signs it's time to outsource

  1. Packing takes up your day. If you spend hours a day boxing orders, that time is missing from purchasing, marketing and your customers.
  2. Dispatches slip. If orders received in the afternoon regularly only ship the next day, both your customers and the marketplace notice.
  3. Mistakes are increasing. Wrong size, wrong color, missing item: each one turns into a return and an unhappy customer.
  4. You're running out of space. If stock is already piling up in the corridor, you can't buy in for the next season.
  5. You're opening a second channel. Alongside eMAG, Allegro or B2B partners (wholesalers, retail chains), shared stock becomes hard to track by hand. eMAG and Allegro from one warehouse
  6. You can't handle peak season. If order volumes jump in season, your own team can only keep up with overtime or delays.

When doesn't it pay off (yet)?

Outsourcing isn't the right decision for everyone, and it's better to know that up front.

  • Very few orders. Below roughly 50 orders a month, packing yourself is typically still more cost-effective. We also suggest talking from that volume, although setup with a ready-made connector is free.
  • Made-to-order products. If you make every item after the order comes in, there's nothing to store in advance.
  • Every parcel is unique. If every order gets a handwritten note or a custom selection, outsourcing only helps in part. Many custom requirements can be turned into rules, though: custom packaging, inserts, kitting. Value-added services

Got another question? Write to us.

How do I calculate my own warehouse's cost per order?

Add up one month's costs: rent and utilities, packers' wages including cover, packaging materials, carrier fees, software and your own time. Divide this by your monthly order count, and compare the itemized fulfillment quote against it.

When doesn't it pay off to outsource your warehouse?

If you have fewer than roughly 50 orders a month, if you make to order, or if every parcel is completely unique.

What should I check first with a fulfillment partner?

The dispatch cut-off, itemized pricing, and how long it takes for returns to get back into stock. After that, ready-made integrations, the client portal and onboarding time.

What happens in peak season if I outsource my warehouse?

The partner's team and capacity handle the jump in orders, so you don't have to organize overtime or temporary staff. With us, orders received by the cut-off ship the same day, even in peak season.
