3PL fulfillment pricing is the single most opaque part of outsourcing your order operation. Most brand operators get a quote, see a number that feels reasonable, sign the contract, and then watch the invoice balloon over the next six months as line items they never noticed start adding up.
This guide breaks down what you are actually paying for, where 3PLs hide cost, and how to read a quote so you know your true cost per order before you commit. It is written for DTC operators shipping anywhere from 50 to 5,000+ orders per month, and it is honest about where Simpl Fulfillment fits in.
What you're actually paying for: the 8 fee categories Every 3PL fulfillment pricing quote, no matter how it is structured, rolls up into eight cost categories. If your quote does not break out all eight, you are not seeing the full picture.
1. Receiving. What it costs to unload your inbound freight, count it, and put it on the shelf. Usually billed per pallet, per carton, or per labor hour. A 20-pallet shipment can cost anywhere from a small flat fee to several hundred dollars depending on the 3PL's model.
2. Storage. What it costs to keep your inventory in the warehouse each month. Some 3PLs bill by cubic foot, others by pallet position, others by bin or shelf. Simpl bills by storage type (small bin, large bin, shelf, or pallet) based on the SKU footprint, not a cubic-foot calculation.
3. Pick. What it costs to retrieve an item from its storage location. Most 3PLs charge per pick, with the first pick included in a base order fee and additional picks priced separately. Simpl's flat-rate model bundles 3 picks into the base order price.
4. Pack. What it costs to put the items into a shipping container with the right dunnage and any custom inserts. Quotes that look cheap on pick often hide the cost in pack.
5. Shipping. The actual postage paid to the carrier, plus any markup or "shipping fee" the 3PL adds. For most brands, this is the largest single line on the invoice. See the next section.
6. Returns. What it costs to receive a returned order, inspect it, restock it, and process the refund. Some 3PLs charge a flat return fee. Others bill receiving, inspect, and restock as three separate line items.
7. Account management. What it costs to actually talk to a human. Some 3PLs include a named account manager in the base price. Others charge for "premium support" or bill account-manager time hourly. Quotes that look cheap up front often skim cost out of this line.
8. Integrations and setup. What it costs to connect your store, configure shipping rules, set up SKU profiles, build kits, and onboard new sales channels. Usually a one-time setup fee plus ongoing change-order fees for new integrations.
A useful exercise: take any 3PL quote you have on the table, list these eight categories, and write the dollar figure your prospective 3PL charges next to each one. If you cannot fill in all eight from the quote alone, that is your first red flag.
How shipping fees work (and why they're the biggest line item) For most DTC brands, shipping postage is 50–70% of the total monthly invoice. Pick-and-pack labor gets the attention because it is the easiest line to compare across quotes, but the shipping line is where margin actually lives or dies.
Three things drive the cost of a shipment.
Carrier rate card. Every 3PL has negotiated rates with USPS, UPS, FedEx, and regional carriers. The size of those discounts varies a lot. A 3PL doing 5 million shipments a year has materially better rates than one doing 200,000. Ask any 3PL you are evaluating to quote a sample shipment on your most common dimensions and weight, then compare against carrier list rates and a service like Pirate Ship to see how much of the published discount you are actually getting.
Dim weight. Carriers bill the greater of actual weight or dimensional weight, which is a volume calculation: length × width × height divided by a divisor (currently 139 for most domestic services). A 1-pound order in a 12×12×6 box is billed at 5 pounds. If your packaging is oversized for your product, you are paying dim-weight tax on every shipment. A good 3PL right-sizes packaging by SKU profile; a lazy one ships everything in the same box.
Zones and surcharges. Domestic shipping is priced by zone (1 through 8) based on the distance between the origin warehouse and the delivery address. A package shipped from a single warehouse to a coast-to-coast customer can cost twice as much as a same-weight package shipped within zone 2. On top of zone math, carriers add surcharges for residential delivery, fuel, peak season, oversized packages, additional handling, and remote-area delivery. Surcharges are not optional and are not negotiable for most brands.
The most common shipping-cost surprise on a new 3PL contract is the surcharge stack. The pick-pack rate looked good, but the 3PL's effective shipping rate, after surcharges and any markup on postage, is meaningfully higher than what you were paying before. Always model your top-10 shipments (the SKU combinations and destinations that actually drive your volume) against any new 3PL quote. Quote averages lie; actual SKUs do not.
The hidden costs nobody quotes upfront This is the section the operator who has been burned reads twice. None of these costs appear on a one-page pricing sheet. All of them show up on the invoice.
Peak surcharges. Most 3PLs add a per-order peak surcharge from October through January. The number is rarely on the published rate sheet. Ask explicitly, in writing, what the peak surcharge is, when it applies, and whether it is per-order or a percentage uplift on pick-pack.
Kit-build fees. Bundles, subscription boxes, and gift sets often look like a single SKU to your store but are assembled from components inside the 3PL. The labor to build the kit is billed separately from the pick-pack on the outbound order. If you ship a subscription box with 6 components, you may be paying for the kit-build labor plus the pick-pack on the outbound shipment.
Project management hours. Onboarding, new SKU setup, photo audits, kit redesigns, peak-season prep meetings, and most one-off requests get billed as PM hours at rates typically between $50 and $150 per hour. The rate is usually in the contract; the volume of hours you will actually consume is not.
Expedited and exception receiving. Standard receiving has a 1–3 day turnaround. Need it on the shelf today because a flash sale is going live tomorrow? That is an expedite fee. Pallet arrived with a missing BOL or unlabeled cartons? That is an exception-handling fee.
Storage minimums. Some 3PLs enforce a monthly storage minimum: you pay for X bins or Y pallet positions whether you use them or not. Common with seasonal brands that under-utilize summer storage and get hit with a charge for empty space.
Change-order fees. Adding a new sales channel, changing a packing-slip template, modifying a shipping rule, or adding a returns app integration may all be billable change orders. Ask for the standard change-order fee schedule before you sign.
Long-tail SKU fees. A few 3PLs charge a per-SKU monthly fee on top of storage. If you have 800 SKUs of slow-moving inventory, that compounds quickly.
The fix is the same in every case. Ask for the full fee schedule in writing (not the sales-deck one-pager) and read the master services agreement before you sign. If a 3PL will not put the fee schedule in the contract, that is your answer.
How to decode a 3PL pricing quote Most 3PL quotes are written to be hard to compare. Three quotes from three vendors for the same brand will use three different units, three different inclusions in the base rate, and three different ways of describing storage. Walk through any quote in this order.
Step 1: Translate to a single unit. Convert every fee to a per-order or per-month figure based on your actual volume. Quote A says "$3.50 base pick fee + $0.45 each additional pick." Quote B says "$5.00 flat per order, includes 4 picks." If your average order has 2.5 items, Quote A costs $4.18 per order and Quote B costs $5.00 per order. But Quote A does not include packaging materials and Quote B does. Always normalize.
Step 2: List what is in the base rate, and what is not. Make a checklist of: pick fee, pack labor, standard packaging (mailer or box), branded packaging, insert cards, dunnage, postage, returns processing, account management, basic reporting, advanced reporting. Mark each line "included" or "extra." Two quotes with the same base rate can be 40% apart on real cost depending on what is bundled.
Step 3: Run your top-10 SKU combinations through the math. Take your 10 most common order profiles from the last 90 days. Run each one through the prospective 3PL's pricing: base order fee, additional picks, packaging, postage based on weight and destination zone. Now you have an apples-to-apples projected invoice. Anything else is marketing math.
Step 4: Add the hidden-cost stack. Peak surcharge × your Oct–Jan volume. Estimated PM hours for onboarding (ask the 3PL for a number, get it in writing). Returns processing × your return rate. Long-tail SKU fees × your SKU count. Add these to the per-order math.
Step 5: Compare like-for-like on storage. Quote A bills $25 per pallet position. Quote B bills $0.65 per cubic foot. Quote C bills by storage type with no cubic-foot math. Convert each to "what does my actual inventory cost per month here," using your average on-hand inventory by SKU footprint. Storage math is the line most often miscompared.
A 3PL that resists this exercise is telling you something about how their pricing is structured. A 3PL that walks through it with you, line by line, is the one to take seriously.
Flat-rate vs per-service: which model wins There are two basic pricing structures in the 3PL market.
Per-service is the traditional model. You get a line item for receiving, a line item for storage by pallet or cubic foot, a per-pick fee, a per-pack fee, postage at the 3PL's negotiated rate plus or minus a markup, returns charged per stage, and account management priced separately. The math gets complicated, but you pay only for what you use. Predictable for ops teams that already know their cost structure cold; opaque for first-time outsourcers.
Flat-rate bundles the per-order operational fees into a single number. Simpl's flat-rate pricing starts at $7 per order and includes 3 picks, postage, and packaging in the base rate. Storage and returns are still billed separately because they scale on different variables, but the per-order line is one number you can plan against.
Neither model is universally cheaper. The honest tradeoffs:
Flat-rate is cheaper if your average order has 1–3 picks and you do not have edge-case SKUs that need special handling. The bundle includes what most DTC brands actually use.
Per-service is cheaper if you have a high-pick average (5+ items per order is common in some kit-heavy categories), unusual SKU dimensions, or operations that need granular cost attribution by SKU line for accounting.
Flat-rate is dramatically easier to forecast. If you are scaling fast or planning a big quarter, knowing your per-order cost is a single number makes margin modeling tractable.
Per-service can mean lower headline cost but higher total invoice if you do not catch every line item before signing.
The honest move: model both. Take your last 90 days of orders, apply the flat-rate math, then apply the per-service math against the specific 3PL you are evaluating. Whichever is lower wins. Read the contract for both, because the per-service quote often has more surcharges and minimum-volume clauses than the headline rate suggests.
Simpl's positioning is flat-rate-by-default because it removes the line-item negotiation that eats the most operator time, and because the brands we serve (50 to 5,000+ orders per month) tend to benefit from the simpler math. We are not the right answer for every brand. We are the right answer for brands who want one number per order, no surprises, and same-day shipping on anything that comes in before 12pm CST.
What 3PL pricing actually costs per month Three scenarios using Simpl's flat-rate-per-order pricing. Most 3PLs do not publish per-service rates, so the tables below show Simpl cost only. Apply the framework above when you have a competing quote in hand.
Scenario 1: 50 orders/month (early-stage DTC brand) Average order: 2 picks, 1 lb, shipped to mixed zones 2–6. 50 SKUs on hand, predominantly small-bin storage. No subscription, no kits.
Pick + pack + packaging + postage (per order × 50). $7.00/order starting × 50 = starting at $350/mo.
Storage (50 SKUs, small-bin). Bin-based; varies by SKU count and storage type.
Account management. Included: dedicated AM, email, same-day responses.
Returns. Per-return, varies with rate.
Setup / onboarding. Included in 5–7 day onboarding.
Indicative monthly total. Starting at ~$350 + storage + returns.
At 50 orders per month, the price difference between pricing models often comes down to whether your storage and account-management line items are bundled or itemized. The Simpl flat-rate is forecastable; a per-service quote is usually only cheaper if you have unusually low storage footprint and zero account-management needs.
Scenario 2: 200 orders/month (growth-stage DTC brand) Average order: 3 picks, 1.5 lbs, shipped to nationwide zones 2–8. 200 SKUs, mix of small-bin and shelf storage. Some kit assembly.
Pick + pack + packaging + postage (per order × 200). $7.00/order starting × 200 = starting at $1,400/mo.
Storage (200 SKUs, mixed bin/shelf). By storage type, no cubic-foot math.
Kit-build labor. Included up to 3 picks per outbound; kit components billed if pre-assembled.
Account management. Included.
Indicative monthly total. Starting at ~$1,400 + storage + returns.
At 200 orders per month, kit-build fees and account-management line items become material. The flat-rate bundle is usually within 10–20% of a tightly negotiated per-service quote; the question for the operator is which model removes the most calendar time spent reading invoices.
Scenario 3: 500 orders/month (scaling DTC brand) Average order: 2 picks, 2 lbs, shipped to nationwide zones 2–8. 500 SKUs, mixed storage. Peak season pushes volume to 1,200/mo for 3 months.
Pick + pack + packaging + postage (per order × 500). $7.00/order starting × 500 = starting at $3,500/mo.
Peak season surge (1,200/mo × 3 months). Same per-order rate during peak (no peak surcharge baked in).
Storage. By storage type.
Returns processing. Per-return; if we ship the wrong order, Simpl covers the return shipping and re-fulfillment.
Account management. Included: dedicated AM, same-day email.
Indicative monthly total. Starting at ~$3,500 + storage + returns.
At 500 orders per month and above, the peak-season surcharge difference is the line that most often decides total annual cost. Brands that scale 2–3x for peak pay materially more under per-service models that apply a peak per-order uplift. Under Simpl's flat-rate, the per-order number is the per-order number. In October and in February.
5 questions to ask before signing a 3PL contract The five questions below are the ones that separate operators who get the quote they signed from operators who get a 30% larger invoice in month four.
1. Can you put the full fee schedule, including peak surcharges and PM hours, in the master services agreement? Sales decks are not contracts. If a fee is not in the contract, the 3PL can change it without notice.
2. What is your per-order cost for my actual top-10 SKU combinations, including postage to my actual destination zones? Make them do the math on your real data, not on a generic example. If they cannot or will not, they do not know their own pricing.
3. What does it cost to onboard, and how long does it take? Onboarding runs anywhere from a week to a quarter at most 3PLs, and some (e.g. ShipBob) charge a one-time onboarding fee on top of the per-order rate. Simpl onboards in 5–7 days, with 1–3 day receiving turnaround and no onboarding fee. Confirm both the time and the dollar cost; both vary widely.
4. What is your order-accuracy guarantee, and who pays when an order ships wrong? "Accuracy" with no cost-coverage clause is a number on a marketing page. Simpl's 99.99% accuracy commitment is paired with at-our-cost error correction. If we ship the wrong order, we cover the return shipping and re-fulfillment. Ask your prospective 3PL: what is the SLA, and what happens when you miss it?
5. Who do I talk to when something goes wrong, and how fast do they respond? Account management quality is the line item that does not show up on the quote and matters most in month seven. Simpl assigns every client a dedicated account manager, reachable by email, with same-day (often faster) responses during business hours. Ask any 3PL: do I get a named human, and what is the response-time commitment?
Frequently asked questions about 3PL fulfillment pricing How much does a 3PL cost per month? 3PL fulfillment pricing for a DTC brand typically runs between a few hundred dollars per month at the very low end and tens of thousands per month at the high end, with the per-order cost as the largest single driver. For a brand shipping 200 orders per month at an average of 2 picks per order, monthly 3PL cost commonly lands in the low-to-mid four figures, depending on storage footprint and shipping zones. Simpl's flat-rate pricing starts at $7 per order, which includes 3 picks, postage, and packaging.
What's included in 3PL fulfillment pricing? A 3PL fulfillment quote usually covers eight cost categories: receiving inbound freight, monthly storage, picking items, packing the order, shipping postage, returns processing, account management, and integrations or setup. Most quotes break these out as separate line items. Some, including Simpl's flat-rate model, bundle the four per-order operational fees (pick, pack, packaging, postage) into a single number, starting at $7 per order, and bill storage and returns separately.
Are 3PL prices negotiable? 3PL prices are negotiable at sufficient volume, generally above 1,000–2,000 orders per month for most providers, and the per-pick fee, peak surcharge, and storage minimum are the lines most commonly negotiated. Below that volume threshold, most 3PLs offer a published rate card with limited flexibility. Flat-rate providers, including Simpl, typically have less negotiation surface on the per-order rate but more flexibility on storage, kit-build, and onboarding fees depending on your inventory profile and ramp plan.
What hidden fees do 3PLs charge? The fees most commonly omitted from a published quote are peak-season surcharges (October–January per-order uplift), kit-build labor, project-management hours billed for onboarding and one-off requests, expedited and exception receiving, storage minimums on under-utilized space, change-order fees for new integrations or shipping-rule edits, and per-SKU monthly fees on long-tail inventory. Ask for the full fee schedule in writing and read the master services agreement. If a fee is not in the contract, treat it as variable.
Is flat-rate 3PL cheaper than per-service pricing? Flat-rate 3PL pricing tends to be cheaper for brands shipping orders with 1–3 picks and standard SKU dimensions, because the bundle covers the operational lines those brands actually use. Per-service pricing can be cheaper for brands with very high pick counts, unusual SKU profiles, or operations that need granular per-line cost attribution. The honest test: model the last 90 days of your orders under both pricing structures using actual SKU and destination data. Simpl's flat-rate starts at $7 per order, bundling 3 picks, postage, and packaging.
How do storage fees work at a 3PL? 3PL storage fees are billed in one of three ways: by cubic foot (volume of inventory stored), by pallet position (one charge per pallet on the floor), or by storage type (small bin, large bin, shelf, or pallet) based on SKU footprint. Simpl uses the storage-type model: each SKU is assigned a storage type based on dimensions, and you pay per the type used. Pallet-position pricing favors brands with consolidated heavy inventory; cubic-foot favors brands with mixed product sizes; storage-type favors brands with high SKU counts and mixed footprints.
What does "pick and pack" actually cost? Pick-and-pack at a per-service 3PL is usually two line items: a per-order pick fee for the first item, an additional per-item pick fee for each item beyond the first, and a separate pack labor fee. Total per-order pick-pack at standard DTC volumes commonly lands in the low single dollars to mid single dollars, before packaging materials or postage are added. Simpl's flat-rate price of starting at $7 per order bundles pick (3 included), pack labor, standard packaging, and postage into one number, so the "pick-and-pack cost" question rolls up to a single line.
The bottom line 3PL fulfillment pricing is not complicated because the underlying operations are complicated. It is complicated because most quotes are structured to make comparison hard. The 8-fee framework above is the same regardless of vendor; the work is forcing every quote into the same shape so you can read them side by side.
Simpl's pitch is straightforward: flat-rate pricing starting at $7 per order, all 8 fee categories named in the contract, dedicated account management included, same-day shipping on anything received before 12pm CST, 99.99% accuracy with at-our-cost error correction, and onboarding in 5–7 days. We are built for D2C brands shipping 50 to 5,000+ orders per month who want one per-order number they can plan against.
If you are evaluating quotes from us or anyone else, the most useful thing you can do is run the top-10 SKU exercise above. The 3PL that walks through it with you is the one to take seriously.
