eCommerce fulfillment services, because delivery speed is a visibility setting
Most sellers treat fulfilment as a cost line and try to make it smaller. On every major marketplace it is also a search input. Shoppers filter by delivery speed before they compare anything else, so the money you save on postage is frequently spent on not appearing in the results at all.
We work out what each order truly costs you to send, what promise that buys you on each channel, and whether a warehouse, the platform or your own back room should be doing it.
The true cost of every order including your own hours, the delivery promise each model buys you, and no commissions from any provider we recommend.
What are eCommerce fulfillment services?
eCommerce fulfillment services cover everything between an order being placed and the parcel arriving: where stock is held, who picks and packs it, which carrier moves it, what delivery promise the buyer is shown, and what happens when the parcel comes back.
Our involvement is advisory and operational rather than physical. We do not own a warehouse, which means we have no reason to recommend one. The work is deciding which model fits your products and margins, selecting and onboarding a provider if you need one, configuring the delivery settings on each channel so they reflect what you can actually do, and watching the metrics that decide whether you stay visible.
If you sell across several channels, this sits directly on top of marketplace management, because where stock lives and what each channel has been promised are the same decision viewed from two directions.
Cheap postage is not cheap if it hides you from buyers
The fulfilment decision gets made on a spreadsheet with one column: cost per order. That column reliably picks self-fulfilment, because posting things yourself looks like it costs the price of a stamp and a box. Two things are missing from it.
The first is your time. Picking, packing, queueing at the post office and handling the resulting questions is real labour, and when a seller prices their own hours honestly, self-fulfilment usually costs considerably more than it appeared to. The second is demand. Delivery speed is a filter on every major marketplace and a stated preference in every shopper survey. A slower promise does not lose you a small percentage of sales, it removes you from the consideration set of everyone who filtered.
So the real question is not which option costs least per parcel. It is which option produces the most profit per unit of stock, once the delivery promise has changed how many of them sell. That comparison sometimes favours the expensive-looking option, and sometimes does not. It depends on your margin, your product size and how much your buyers care about speed, which is why it should be calculated rather than assumed in either direction.
A light bulky item can cost more to send than a heavy small one. Carriers and fulfilment providers price on dimensional weight, so the box matters as much as the scales. Any per-order figure quoted without your real dimensions is a guess, and shrinking packaging is one of the few fulfilment savings that costs you nothing in delivery speed.
Speed is a filter, not a nicety
Buyers narrow by delivery before they compare price or photographs. A slow promise means you are excluded rather than rejected, and exclusion is invisible in your reports.
Your time is the missing cost
Self-fulfilment usually costs more than sellers think, because the hours are unpriced. It is also the cost that grows fastest as order volume rises.
Late dispatch is a metric
Missing a stated handling time damages seller standing on most marketplaces, and seller standing gates placement. One bad fortnight can cost months of visibility.
Returns are part of fulfilment
Return rate, restocking and who pays for shipping are frequently ignored in the model, and on some categories they decide whether the product is viable at all.
Self-fulfilment, third party warehouse, or the platform's own
There are only three answers, and most growing sellers end up using more than one at once. The skill is knowing which products belong in which, rather than picking a single model for the whole catalogue.
You pack it
Best for low volume, fragile or personalised items, and anything where the unboxing is part of the product. Breaks when volume rises or you want to take a holiday.
A third party warehouse
Best for steady volume across several channels, since one pool of stock can serve them all. Breaks when volumes are too low to clear minimums, or storage fees outrun slow-moving lines.
The platform fulfils it
Best for fast-moving items on that marketplace, where the badge and filter eligibility are worth the fee. Breaks when stock sits, because long-term storage charges punish it hard.
The useful mental model: platform fulfilment buys demand, a third party warehouse buys capacity, and self-fulfilment buys control. Decide which of those you are short of, then let that pick the model rather than the per-order cost alone.
Storage fees are how slow products quietly become losses
Every warehouse and every platform fulfilment programme charges for space, and those charges rise the longer something sits, sharply so in the final quarter of the year when space is scarce. This creates a failure mode that catches careful sellers off guard: a product with a healthy margin per sale that sells slowly can cost more in storage across a year than it earns.
Nobody notices because the storage bill arrives as one number for the whole account rather than attributed to the products causing it. The product looks profitable on its own line and the fee looks like general overhead, so both survive review indefinitely.
The fix is unexciting and effective: attribute storage cost per SKU, look at it next to sell-through rate, and act on the slow ones before the expensive season rather than after it. Sometimes that means a discount to clear, sometimes moving those lines to self-fulfilment, and occasionally accepting that a product should not be restocked at all.
How our eCommerce fulfillment services run
Cost what you actually do now
Packaging, postage, storage and your own hours at a real rate, per order and per product. Most sellers see a number here they did not expect.
Model the alternatives properly
Each option costed on your real weights, sizes and volumes, including storage and returns, with the demand effect of a faster promise estimated rather than ignored.
Select and onboard
Shortlisting providers against your actual profile, checking the contract terms that hurt later, and running a pilot before anything moves at scale.
Set the promises and watch them
Handling times and delivery options configured per channel to match reality, then dispatch performance monitored so a drift is caught before it becomes a metric problem.
We move a subset of products first on every transition. Moving an entire catalogue in one weekend is how sellers discover a provider's limitations with all of their stock already inside it.
What our eCommerce fulfillment services include
True cost per order
Your current fulfilment costed honestly, including labour, packaging, storage and returns, per product rather than as an average.
Model comparison
Self, third party and platform fulfilment costed on your real dimensions and volumes, with the delivery promise each one buys stated plainly.
Provider selection
Shortlisting and reference checking against your category and volume. We take no commission from providers, which is the only way this advice is worth anything.
Contract review
Minimums, storage bands, receiving fees, exit terms and how prices change. The costly clauses are rarely the headline pick and pack rate.
Integration and setup
Orders and stock flowing between your channels and the warehouse, with a pilot batch proving it before the catalogue follows.
Channel delivery settings
Handling times, cut-offs and shipping options configured per channel so the promise shown to buyers is one you can keep every time.
Storage cost attribution
Space charges assigned to the products causing them, reviewed against sell-through so slow lines are dealt with before the expensive season.
Returns handling
Where returns go, who inspects them, what gets restocked and what the whole process costs you per order rather than per return.
Dispatch metric monitoring
On-time dispatch, tracking upload and late shipment rates watched across channels, because these gate your visibility everywhere.
When you should keep packing them yourself
Volume is still low
Most third party warehouses have minimums that make small volumes expensive per order. Below those thresholds, doing it yourself is genuinely the right answer.
The product is personalised
Made to order, engraved or hand-finished items rarely survive a standard pick and pack process, and the exceptions cost more than they save.
Presentation is the product
If the unboxing is part of why people buy and recommend you, outsourcing it removes something your reviews are probably built on.
Your margin will not carry it
Low-value items are where fulfilment fees do the most damage. Sometimes the answer is raising order value through bundles rather than changing warehouse.
Before deciding anything, put a typical order through our eCommerce profit margin calculator at each fulfilment cost. If the gap between models is small, keep the one that costs you the least attention.

Our fee is separate from what you pay a warehouse or a platform, and we take nothing from providers. A referral commission would make every recommendation on this page worthless, so we do not accept them.
Fulfilment audit
$700 to $2,000 once. True cost per order and per product, the three models compared on your real numbers, and a recommendation with the reasoning shown.
Selection and transition
$2,000 to $7,000 once. Provider shortlisting, contract review, integration, pilot batch and the channel settings updated to match the new promise.
Ongoing oversight
$600 to $2,000 a month. Dispatch metrics, storage cost attribution, returns performance and provider issues chased on your behalf.
If the audit concludes that your current setup is already the right one, that is the finding you get. It happens often enough that we mention it here rather than discovering it awkwardly later.
Common questions about eCommerce fulfilment
When packing orders is consuming time you should be spending on the business, when volume is steady enough to clear a provider's minimums, or when you cannot offer a competitive delivery promise from where you are. Volume alone is a poor trigger. Plenty of sellers move too early, pay minimums on volumes that do not justify them, and lose the flexibility that was making their product distinctive.
For fast-moving items on that marketplace, usually yes, because the delivery badge and filter eligibility change how many units sell rather than just how they ship. For slow-moving items it is frequently a loss, since storage charges compound the longer stock sits and rise steeply in the final quarter. The honest answer is per product rather than per business, which is why most established sellers run a mixed model.
Usually yes, and it is one of the main reasons to use a third party at all, since a single stock pool serving every channel removes the split-inventory problem entirely. The exception is platform fulfilment programmes, which generally require stock to sit in their own network. Sellers who use both end up holding stock in two places, which is workable but needs the split deciding deliberately rather than by accident.
Third party pick and pack is commonly a few dollars per order plus shipping and storage, and platform fulfilment is usually higher per unit but includes the delivery promise. Both vary enormously with size and weight, and dimensional weight rules mean a light bulky item can cost more to send than a heavy small one. Any quote given without your real dimensions is a guess, including ours.
Set handling times you can meet on your worst week rather than your best, and upload tracking within the stated window every time. Most sellers set an optimistic handling time to look competitive and then breach it during their busiest fortnight, which is exactly when the damage costs most. A slightly longer promise that you always keep beats a fast one you sometimes miss.
On most marketplaces it is close to mandatory, because shipping cost is factored into how results are ranked and filtered, and buyers compare the delivered total anyway. On your own store it is a pricing decision rather than a moral one: the cost has to sit somewhere, and building it into the product price with a clear threshold usually converts better than showing it at checkout, where it is the most common reason baskets are abandoned.
They go back to the warehouse and are handled under whatever terms you agreed, which is precisely the part sellers skim in the contract. Ask specifically who inspects a return, what standard decides whether it is resellable, what the fee is per return and how long restocking takes. In categories with high return rates, these answers matter more to your economics than the pick and pack price does.
