Fixed cost that does not flex
Rent, racking and equipment cost the same in February as in November. A 3PL converts that fixed cost into a variable one that moves with your volume.
Comparison
Running your own warehouse versus using a 3PL
The comparison most brands make is rate-per-order against their own labour cost, and it is the wrong comparison. Your own warehouse has costs that never appear as a line item anywhere.
- Written to be useful even if you decide to stay in-house
- Covers the costs that never appear as line items
- Includes when in-house is the better answer

The situation
Why the obvious comparison is misleading
A 3PL quotes you a rate per order. Your own warehouse does not present you with one, so people compare a full price to a partial one.
- Rent and utilities counted, but not the capital tied up in racking and equipment.
- Hourly labour counted, but not recruitment, training, turnover or management time.
- No line item for the founder hours spent on the warehouse instead of the brand.
- Peak staffing solved by everyone working weekends, so it looks free.
- Capacity risk invisible until the month you outgrow the building.
- Carrier rates negotiated alone at your volume rather than at a 3PL's.
- Software, insurance, workers compensation and compliance spread across other budgets.
What we run
The costs that do not show up on an invoice
Management attention
Somebody senior is running the warehouse. That person's time is the most expensive input in the whole operation and it is never costed.
Peak staffing
Seasonal hiring, training and the quality dip that comes with temporary labour. A 3PL absorbs this across many customers.
Capacity as a step function
You do not grow into 20% more space. You move buildings, which is a project, a cost and a risk all at once.
Carrier leverage
Rates are a function of volume. Your volume alone is smaller than the volume a 3PL aggregates.
Single points of failure
One person who knows where everything is, one forklift, one building. All fine until one of them is unavailable.
The other direction
When keeping it in-house is the right call
The right choice depends on your products, volume, and team.
Fulfillment is part of the product
If every order needs highly personal or changing assembly, in-house fulfillment may fit best. Walk a prospective provider through that work before deciding.
Highly specialised handling
Product requiring unusual equipment, licences or handling conditions is often cheaper to run yourself than to find and pay a provider to replicate.
Very low volume
Below a few hundred orders a month, the overhead of managing a 3PL relationship can exceed what it saves.
You already have the building and the people
If the space is committed on a long lease and the team is stable and not the constraint, the sunk cost is real. The question then is capacity, not cost.
Reference
The honest comparison
Scroll the table sideways to see every column
| Your own warehouse | A 3PL | |
|---|---|---|
| Cost shape | Mostly fixed. Same in your quiet month. | Mostly variable. Falls when volume falls. |
| Control | Total. You set every process. | Contractual. You set requirements, they run them. |
| Capacity | Steps up in building-sized jumps | Flexes within the provider's network |
| Peak | You hire, train and supervise | Absorbed across many customers |
| Carrier rates | Negotiated at your volume | Negotiated at aggregated volume |
| Speed of change | Immediate. It is your floor. | Requires a conversation and sometimes a fee |
| Management load | High and permanent | Low if it works, high if it does not |
| Unusual requirements | Trivial. Just do it. | Depends entirely on the provider |
| Best when | Highly specialised handling, or fulfillment IS the product | Volume varies, channels multiply, or the team is the constraint |
Proof
A brand that made this exact decision
Googan Squad, published by Nile.
- 1–3 daysOrder to shipment, down from 5–10 in their own warehouse
- ~10%Reduction in fulfillment cost
They ran their own warehouse. Influencer-driven launches produced demand spikes it could not absorb, and it was expensive. Both the speed and the cost improved after moving, which is the combination that makes the decision easy in hindsight and hard in advance.
FAQ
Questions we get asked
Not covered here? Ask us directly and you will get a specific answer rather than a brochure.
Ask a questionAt what volume should we outsource?
Look at cost, capacity, and the time your team spends on the warehouse. Outsourcing may help when those demands start taking attention from the rest of the business.
Will a 3PL definitely be cheaper?
Not necessarily on a pure cost-per-order basis, especially if your own operation is lean and your volume is steady. It is usually cheaper on total cost once you include management time, peak staffing and the cost of capacity you are not using.
Can we do both?
Yes, and some brands do. Keeping a small in-house operation for special or high-touch orders while a 3PL runs volume is a reasonable hybrid, though it does mean two inventory positions.
How should we plan the transition?
Start with inventory, system testing, and a transfer schedule. Our switching guide walks through the decisions to make with both warehouse teams.
