Why order volume alone isn’t enough to decide
Two businesses with the same monthly order volume can be in radically different situations. A single-product brand with stable stock and few returns can run its logistics in-house for far longer than a multi-SKU, seasonal business selling across several channels.
The number of active SKUs, average items per order, return rate, seasonality, and number of sales channels matter at least as much as raw volume. It’s the combination of these factors, not one isolated number, that should guide the decision.
Signal 1: growth outpaces in-house capacity
The most obvious signal is also the one most often ignored for too long. When every order spike forces businesses to pull staff from other departments or rent extra storage space at the last minute, the in-house setup has hit a structural limit. Continuing to absorb growth this way can make costs higher, less predictable, and harder to steer. A 3PL cost simulation based on actual operating data provides a more reliable basis for comparing the two models.
Signal 2: errors and delays increase alongside volume
A setup that worked well at one level of activity can become hard to sustain as volumes grow. Picking errors, undetected stockouts, dispatch delays, and customer complaints tend to increase alongside volume, and not necessarily in a proportional way: processes designed for a certain pace of activity often reach their limits sooner than expected. If your error rate and delays keep increasing as volumes grow, the organisation has likely reached an operational limit.
Signal 3: seasonal peaks become unmanageable
Some businesses face predictable peaks (seasonal sales, end-of-year holidays, back-to-school) that can push volumes to several times their usual level within a few weeks. Hiring and training temporary staff for a few weeks a year, year after year, takes up a huge amount of management time for a result that’s often disappointing in terms of service quality. A 3PL pools infrastructure, industrialises its processes, and plans resources across multiple clients. Its ability to absorb a peak still depends on the quality of forecasts and the contractual commitments agreed in advance.
Signal 4: a new sales channel demands more than you can deliver alone
Launching on a marketplace or entering a new market often changes the equation. Each platform sets its own dispatch deadlines, tracking formats, and returns rules. Building these integrations in-house, for every new channel, requires a technical and human investment that few businesses can justify against the initial volume that channel generates.
Signal 5: catalogue or order complexity explodes
A catalogue that grows significantly, orders containing an increasing number of different items, or the arrival of products with specific storage constraints (fragility, weight, temperature) all significantly increase logistics complexity, independent of order volume. This complexity is often underestimated until it causes visible operational bottlenecks.
Signal 6: logistics is pulling the team away from its core focus
This is the most strategic signal, and often the last one noticed. When founders or the sales team spend a significant share of their time packing boxes, resolving delivery issues, or managing stockouts, the business diverts resources away from product development, marketing, and customer relationships. This opportunity cost never shows up on a balance sheet, but it slows growth just as much as a cash flow problem would.
Quick diagnostic grid
Before contacting a provider, it’s worth taking an honest look at your own situation. For each signal, tick the box that matches your current situation.
| Signal | Present | Partially present | Absent |
|---|---|---|---|
| Growth outpaces in-house capacity | ☐ | ☐ | ☐ |
| Errors and delays increase alongside volume | ☐ | ☐ | ☐ |
| Seasonal peaks become unmanageable | ☐ | ☐ | ☐ |
| A new channel demands more than you can deliver alone | ☐ | ☐ | ☐ |
| Catalogue or order complexity explodes | ☐ | ☐ | ☐ |
| Logistics pulls the team away from its core focus | ☐ | ☐ | ☐ |
The more signals marked “present” or “partially present”, the more seriously the question of outsourcing deserves to be explored, regardless of order volume.
How to confirm it’s the right time before reaching out to providers
Beyond this grid, it’s worth quantifying, even roughly, the real and often invisible cost of the current situation: overtime, errors, customer dissatisfaction, missed commercial opportunities. This assessment then makes it possible to approach providers with a clear scope to outsource, rather than a vague sense that “we probably should outsource at some point.”
