In-house fulfilment works until order volume, product complexity, or peak swings outgrow your space and staff. Outsourcing swaps fixed costs for variable ones but gives up some control. A small pilot with one product range is the safest way to test the move before committing.
Most product businesses start by packing orders themselves, and that is usually the right call. The question is when the garage, the spare room, or the small unit stops being an advantage. The answer depends on a few easy-to-measure thresholds.
At What Point Does In-House Fulfilment Stop Working?
Three thresholds tend to arrive in the same order: volume, complexity, and peaks. Volume comes first, and many sellers feel the strain between 50 and 100 orders a day, when packing starts to take up most of the day. Complexity follows, as soon as the catalogue includes bundles, fragile items, or products that need kitting.
Peaks are the third. A business that handles 40 orders a day in spring and 300 in the last two weeks of November cannot staff for the peak without carrying the cost all year. Founders in this position often start by choosing the right fulfilment partner to take on the repetitive work, so they can spend their time on product and sales.
The table below outlines the usual thresholds and what each looks like in practice.
| Threshold | Typical warning sign | What it costs you |
| Volume | Packing takes more than four hours a day | Less time for product and marketing |
| Complexity | Frequent pick errors on bundles or variants | Refunds, reshipments, and bad reviews |
| Peak swings | Orders triple for a few weeks each year | Overtime, temporary staff, or late dispatch |
| Space | Stock is stored in living or working areas | Slower picking and lost stock |
When two or more of these appear together, the case for outsourcing is usually strong. The next step is to price the in-house option properly, and most sellers undercount it.
What Does In-House Fulfilment Really Cost?
The visible costs are easy to list: packaging, carrier fees, and perhaps a part-time packer. The hidden ones are larger. Space costs money even in a spare room, because that space could hold stock for sale or serve as a workspace.
Labour is the biggest item. Count the founder’s own hours at a realistic hourly rate, plus holiday cover, sick days, and training for new hires. Someone who packs for four hours a day isn’t selling, designing, or answering customers during that time.
Errors add a further layer. Each mis-pick costs a refund or reshipment, the return postage, and some goodwill. Insurance, equipment, and label and stock-control software complete the picture. Once these are added, many sellers find their in-house cost per order is higher than a provider’s quote.
What Do You Give Up by Outsourcing?
Outsourcing isn’t free of trade-offs, and it helps to name them before you sign. Control is the main one. Your stock sits in someone else’s building, so you rely on their accuracy, their cut-off times, and their handling of problems.
The other costs are specific:
- Minimum monthly fees or order volumes that apply in quiet months.
- Storage charges that rise for slow-moving stock.
- Less flexibility for last-minute packaging changes, handwritten notes, or personal touches.
- Dependence on integration quality between your shop and the provider’s system.
- Switching costs if the relationship does not work out.
None of these is a reason to avoid outsourcing, but each is a reason to read the contract carefully and test before fully committing. A short trial exposes most of these issues at low risk.
How Do You Pilot Outsourced Fulfilment Before Committing?
A pilot should be small, measurable, and time-limited. Choose one product range or one sales channel, ideally one with predictable demand and simple packing. Send a limited amount of stock and route only those orders to the provider for four to six weeks.
Track four numbers during the trial: pick accuracy, dispatch time against the promised cut-off, damage rate, and cost per order including all surcharges. Compare them with your in-house figures from the same period. If the provider matches or beats you, widen the range in stages.
The same thinking applies in manufacturing, where makers have long weighed doing the work themselves against buying capacity from outside. Coverage of how on-demand manufacturing is expanding in Europe shows the same logic at work: variable capacity lets a small business scale without owning every step.
Keep a rollback plan too. Hold some stock back and keep your packing materials until the pilot has run through at least one busy period.
Frequently asked questions
When should I stop fulfilling orders myself?
When packing takes much of your working day, errors are rising, or seasonal peaks overwhelm your space and staff. Many sellers reach this point at 50-100 orders a day.
Is outsourced fulfilment cheaper than doing it in-house?
Often, once labour, space, errors, and packaging are counted. The answer depends on volume, product size, and the provider’s fee structure.
What do I lose by outsourcing?
Some direct control over packing and timing, plus exposure to minimum fees and storage charges. A clear contract and a pilot reduce these risks.
How long should a pilot last?
Four to six weeks is common, and longer if you want to see a busy period.
Can I keep some orders in-house?
Yes. Many sellers outsource standard products and handle custom or high-touch orders themselves.
