Outsourced fulfillment means a third-party logistics company, a 3PL, stores your inventory, picks and packs each order and ships it under your brand, while you keep running the store. Whether that beats doing it yourself comes down to two numbers worth writing down: what an order really costs you to ship in-house once your own hours are counted, and what a 3PL bill would come to once storage, receiving, surcharges and any monthly minimum are added to the quoted per-order rate.
It is usually time to outsource when the count shows your own hours have become the most expensive labor in the operation and a month's orders would cover a 3PL's minimum without stretching. It is too early when a minimum would be billing you for orders you don't have yet, or when your in-house setup is already faster and cheaper than any quote you can get.
Three ways to ship, and where a 3PL fits
Early brands ship one of three ways. In-house, you hold the inventory, pack every order and buy postage yourself. Carrier-direct, you still hold and pack the inventory but buy labels through a shipping platform or a carrier account, usually for less than you would pay at the counter. With a 3PL, you send inventory to their warehouse once, orders flow from your store to their system automatically, and tracking flows back to your customer. The first two are stages of the same thing. The third is a different operating model, and the switch deserves a real count before you make it.
The signals that matter more than an order count
Order volume is a lagging signal. By the time a round number feels like the trigger, the costs below have usually been piling up for months. Watch for these instead:
- You are the packer. A founder's hour is usually the costliest labor in the building, and the only one nobody invoices. If you spend Saturday mornings taping boxes, price those hours in the count below instead of treating them as free.
- Shipping problems are showing up in reviews. Wrong items, late packages and crushed boxes stop being rare and become a pattern. A bad week happens to everyone; a pattern is worth costing out, because the refunds and reships belong in your in-house number.
- Same-day shipping has quietly slipped. Either you commit to it and burn out, or you give it up and conversion suffers.
- Inventory lives in three rooms. Garage, kitchen and spare bedroom means you are paying for space in walking, searching and miscounts rather than rent, and that belongs in the count too.
- Every Q4 means renting space and hiring help. If the plan for peak is to survive it rather than grow through it, add what last year's scramble cost to the count.
- One good week would break the process. A press mention, a viral post or a first wholesale order can double a month's volume overnight. If you don't know how you'd ship it, you need a plan before it arrives.
None of these settles the question on its own. One might just mean you need a better shelving plan, and several together still only tell you it is time to run the count below.
Count what in-house really costs
In-house looks cheap because most of its costs never appear on an invoice. Take your last full month, add up the following, and divide by the number of orders you shipped. That is your real in-house cost per order.
- Labor, including yours. Every hour anyone spent receiving stock, picking, packing, printing labels, fixing mistakes and dropping off at the carrier. Price your own hours at least at what a packer would cost you with payroll taxes added, and higher if that time could have gone to product or marketing.
- Postage at the price you actually pay. Counter prices run well above commercial prices. USPS's published price list puts a 1-pound USPS Ground Advantage package to a zone 5 address at $11.70 at retail and $9.29 at the commercial price, a gap of about $2.40 on a single label. A shipping platform or a carrier account can close part of that gap on your own. Whether a 3PL's postage closes more of it depends on the carrier rates in its quote, so compare the postage line on an actual quote with what you pay today instead of assuming the warehouse wins.
- Packaging. Boxes, mailers, tape, dunnage and inserts, bought in small quantities.
- Space. The rent on a storage unit or the share of your lease, plus shelving and the room you can't use for anything else.
- Software. The shipping platform, the inventory tool, the label printer.
- Mistakes. Refunds, reships, replacement product and the support hours that go with them.
Most of the surprise sits on the labor line, because it is the only cost you were never billed for.
Count what a 3PL really costs
A 3PL bill is honest in the opposite direction: everything is on one invoice, which makes it look more expensive on paper even when it is cheaper in practice. Before comparing, build the full per-order number from the quote:
- The per-order fee, and what it includes. Some 3PLs quote one rate covering the pick, the packing, the packaging and the postage. Others bill a pick fee, a per-item fee, a pack fee, packaging and postage as separate lines. Neither is wrong, but a low headline number with four add-ons can cost more than a higher all-in rate.
- Postage. If it is not inside the per-order rate, ask for the carrier price you will actually pay, not a list price.
- Storage. Billed for the space your inventory occupies, usually by bin, shelf or pallet. Slow-moving stock costs money every month it sits.
- Receiving. Some 3PLs charge per pallet or per hour to check in inbound inventory; some include it.
- Carrier surcharges. Residential delivery, oversize parcels, peak season and address corrections are carrier charges that a 3PL passes along or marks up under its terms. Ask how each one is handled.
- Returns, kitting and projects. Each has its own rate.
- The monthly minimum. Many 3PLs set one. Ask what it applies to: a minimum on fulfillment fees alone, with postage billed separately, looks lower than a minimum on an all-in rate that already includes postage. How 3PL minimums work walks through the common structures.
- Your time, still. Managing a partner is work: checking invoices, coordinating inbound shipments, answering the warehouse's questions about a new SKU. It is far less than packing, but it isn't zero.
As a concrete example, Simpl's fulfillment pricing starts at $7/order with picks, packing, postage and packaging included. Storage is billed by the storage type your inventory uses (small bin, large bin, shelf or pallet), and receiving is free for every client, though inbound shipments that don't follow our receiving guidelines can be charged under our terms. Carrier surcharges, when they apply, are billed under our terms too. Standard ecommerce fulfillment accounts have a $750 monthly minimum, billed pay-the-difference: if a month's order charges come to less than $750, we bill the shortfall so order charges reach $750, and storage, returns and any carrier surcharges are billed on top. For light packages on standard shipping that is roughly 90 to 100 orders a month; heavier, larger or faster shipments reach it with fewer orders. The pricing page has the detail, and the 3PL pricing guide explains how other providers structure the same fees.
If the answer is "not yet"
If a month's order charges wouldn't come close to a 3PL's minimum, keeping fulfillment in-house for now is often the honest call, and there is nothing wrong with it. Use the time to make in-house cheaper and the eventual move easier:
- Stop paying counter prices. USPS sells labels online at commercial prices through Click-N-Ship, and shipping platforms that resell USPS postage typically pass those prices through from the first label. A business account opened directly with UPS or FedEx may get you discounts, but how much depends on the carrier and your volume. Price one of your typical labels through each before you decide. It is often the biggest line you can cut without changing anything else.
- Batch the work. Pack once or twice a day at set times instead of order by order, and keep a repeatable packing setup so a helper can take it over.
- Buy hours before you hire a person. A part-time packer for a few hours on your busiest days buys back founder time without a payroll you can't yet support.
- Keep clean data. Accurate SKUs, barcodes, weights and dimensions make a future 3PL onboarding fast and make your own picking faster today.
- Plan for a spike. Know in advance who you'd call for temporary help, where overflow stock would go, and which 3PL you'd talk to if a month doubled. Some brands run a hybrid for a season, packing the core catalog themselves and sending overflow or a single large order to a partner.
Re-run the count every quarter, or whenever something changes: a new sales channel, a wholesale order, a hire you're about to make. The moment to look again is when your own hours are the bottleneck and a month's orders would clear the minimum on their own.
If the answer is "now": what changes, and what doesn't
What changes:
- You stop touching boxes. Obvious, but a real adjustment after years of being hands-on.
- Inbound becomes the new bottleneck. Inventory has to reach the warehouse and be checked in before it can ship. At Simpl that takes 1 to 3 days after it arrives; plan reorders around it.
- You pay for capacity rather than labor. Slow months still cost something, and the busy ones are the warehouse's to staff rather than yours.
- Carrier problems get a partner. When a package is lost or damaged in transit, a good 3PL files the carrier claim for shipments it sent. Simpl does.
What stays yours:
- Customer support. The 3PL ships the order. "Where is my package" emails still land with you, and the shipping notification your customer receives comes from your store platform's settings, not from the warehouse.
- Inventory decisions. What to stock, how much and when to reorder. The 3PL executes; you decide.
- Packaging and unboxing, if you want them. Custom packaging, inserts and kitting are things a 3PL can run from your rules and your materials. The first weeks are for making sure the process matches what you'd do yourself.
- Watching the numbers. Check accuracy, inventory counts and your invoices closely in the first months. A good partner expects it.
When staying in-house wins
Outsourcing isn't the right move for every brand, and some of the clearest cases for staying have nothing to do with size.
- Your in-house operation already beats the quotes. A brand with a trained team, commercial postage and a well-run space can ship faster and cheaper than a 3PL it would be paying a margin to. If the real per-order number from your count is lower than the all-in quote, keep it.
- The unboxing is the product. A hand-assembled, highly customized experience you can't document for someone else to run is worth protecting.
- Handling or regulatory constraints. Some products carry licensing, security or compliance requirements that make it impractical for inventory to leave your facility.
- You're below the minimums you're being quoted. See the "not yet" section above, and look again when a month's orders would clear the minimum on their own.
Comparing quotes without getting burned
Pick a 3PL on headline price alone and you'll pay for it later. How to choose a 3PL covers the full evaluation; these are the questions that catch the most trouble on the first call.
- What exactly does the per-order rate include? Get the all-in number per order for your actual products before you compare anything, and ask for a sample invoice for a month like yours.
- What does the minimum apply to, and how is a shortfall billed? Fulfillment fees only, or an all-in rate with postage inside it. The same dollar figure means something different when postage counts toward it.
- What is the same-day cutoff, and what happened to it last peak? Ask specifically whether the cutoff moved earlier in November, whether same-day slipped to next-day, and how far behind receiving ran. Those are the capacity problems you would inherit.
- What's the accuracy rate, and who pays when the warehouse gets it wrong? A number without a cost-coverage commitment is marketing. The useful version says what the warehouse covers when it gets one wrong. Simpl's, for example, is 99.99% order accuracy with errors corrected at our cost, including return shipping and re-fulfillment.
- Who do I actually reach, and how fast? A named person or a ticket queue, by email or by phone, and the response time they will put in writing. The answer matters most in the week something goes wrong.
- Does it connect to where I sell? Ask about your store platform and each marketplace by name, and whether the connection is the warehouse's own integration or a third-party connector with its own cost and failure points. Inventory sync and tracking sync are the two things to test before go-live.
- Where will my orders ship from, and with which carriers? Location sets transit times, and the number of locations sets how your inventory is split. One warehouse means one inventory pool and simpler inbound; several means shorter transit for some customers and stock to balance between buildings.
- How long is the term, and how do I leave? Read the exit terms before you read the price: the contract length, whether it auto-renews, the notice period and any offboarding fees for shipping your inventory out.
- What does onboarding take, and what do they need from me? Ask for the timeline, the setup fee if there is one, and the SKU data they need before inventory can ship. At Simpl, standard onboarding runs 5 to 7 days with no onboarding fee; what happens between signing and the first order shipping is its own guide.
Next step
If your count says it's time, see Simpl's pricing or get started with your actual catalog and volume. Ecommerce fulfillment is what we do most. If the count says not yet, keep it and run it again next quarter. Either answer is a good one when it comes from the numbers.
