At some point, packing orders from your spare bedroom stops working. Maybe you’re doing 50 orders a day and your kitchen table is buried in bubble wrap. Maybe a shipping error just cost you your best customer. Maybe you’re staring down Q4 and know you can’t survive it doing fulfillment yourself. Whatever got you here, you’ve decided it’s time to hand shipping over to a third-party logistics provider — a 3PL.
Knowing how to choose a 3PL well is one of the more consequential operational decisions you’ll make as your store scales.
The problem is that “3PL” covers everything from a two-person warehouse in Ohio to a publicly traded logistics company with dozens of facilities. Picking the wrong one doesn’t just cost you money — it costs you customers, because shipping problems show up in reviews, not spreadsheets. Here’s how to choose a 3PL that actually fits your store, step by step.
1. Know Your Own Numbers First
Before you request a single quote, you need to know your own shipping profile cold. 3PLs price based on your specifics, and vague answers get you vague — usually inflated — quotes back. At minimum, have these numbers ready before you reach out to anyone:
-
Where your customers actually are (a West Coast-heavy customer base needs different fulfillment center placement than a nationwide spread)
If you don’t have exact figures, pull your last 90 days of order data from Shopify or Amazon Seller Central. A 3PL that quotes you a price without asking for any of this is either guessing or padding the number to cover their own risk.
2. The Five Things That Actually Determine Fit
Every 3PL will tell you they’re reliable, affordable, and easy to work with. That’s marketing. What actually separates a good fit from a bad one comes down to five measurable things:
| Criteria | What to actually look for |
| On-time delivery performance | Their real on-time percentage over the last 12 months — not a target number |
| Pricing transparency | A clear rate card with no vague “contact us” line items |
| Communication & responsiveness | How fast they answer before you’re a paying customer |
| Customs & documentation | Whether they handle customs brokerage in-house or outsource it — outsourcing adds a hand-off point where shipments get lost |
| Insurance, tracking & risk management | What’s covered automatically, what requires opt-in, and who eats the cost when something is lost or damaged |
These aren’t arbitrary categories. They’re worth formally scoring when comparing multiple providers, because ‘gut feeling’ falls apart fast once three quotes come back within a few dollars of each other. This is really the core of how to choose a 3PL: comparing providers on the same five things, not on vibes. In short, this is how to choose a 3PL you can actually trust.
3. Questions to Ask Before You Sign Anything
A sales call will always sound good. These are the specific questions that surface what a sales call won’t:
- What’s your minimum monthly commitment, and what happens if I don’t hit it? Are storage fees flat per pallet or bin, or do they scale with how long inventory sits?
- Do you integrate directly with Shopify or Amazon, or does someone need to manually sync inventory?
- PricingWhat’s your average pick-and-pack turnaround, from order received to shipped?that looks too good, with no clear explanation why
- Who’s my point of contact when something goes wrong — a dedicated rep, or a shared support queue?
- What does offboarding look like if I switch providers later? Get this in writing — some 3PLs make it deliberately slow to get your own inventory back.
- Do you have experience with my specific product category? A 3PL that mostly handles apparel may not have the right setup for fragile electronics or perishables.
If a provider is cagey on any of these, that’s information too.
4. Red Flags Worth Walking Away From
A sales call will always sound good. These are the specific questions that surface what a sales call won’t:
- No written SLA (service-level agreement) — only verbal promises
- Pricing that looks too good relative to competitors, with no clear explanation why
- Reluctance to provide references from current clients in your product category
- No clear, specific process for handling damaged or lost shipments
- Long-term contracts with steep early-termination penalties and no pilot period offered
Any one of these alone isn’t automatically disqualifying. Two or more together usually is.
If a provider is cagey on any of these, that’s information too.
5. Why a Structured RFP Beats ‘Just Asking for a Quote’ When Choosing a 3PL
Most sellers email three 3PLs some version of ‘what would you charge to fulfill my orders?’ and end up comparing three answers to three slightly different questions — because each provider assumed different things about volume, service level, and scope. That’s not actually a comparison.
