Choose a 3PL for your Shopify brand by testing fulfillment execution, system workflows, and the complete warehouse invoice against your actual orders. Keep parcel and freight contracts in your brand's name, so warehouse selection stays separate from transportation rates and switching warehouses never requires surrendering your rates.
What goes into the operating brief?
Build a one-page brief from your real Shopify orders before contacting anyone. Give every candidate the same document, because a proposal written against assumptions compares warehouses you never described.
Include SKU dimensions and weights, order composition, packaging instructions, receiving formats, returns rules, and the exceptions that matter to you: bundles, inserts, fragile items, lot tracking, and expiration dates where they apply. Mark each item required or preferred. A required workflow needs evidence in the demonstration; a preferred feature needs an honest explanation of the trade-off.
| Area | What to provide | What to verify |
|---|---|---|
| Orders | Actual order lines and item combinations | How picking and packing match the work |
| Receiving | Inbound formats and inventory records | Discrepancy and putaway procedures |
| Packaging | Carton, insert, and handling instructions | Who supplies materials and approves substitutions |
| Returns | Inspection and disposition rules | When inventory becomes sellable again |
| Service levels | Cutoffs and exception handling | Written definitions, reporting, and escalation |
The 3PL pricing breakdown shows which charges belong in that comparison.
How do you test the Shopify workflow?
A connection is not a process. Ask for a demonstration built on representative orders, then deliberately break things: edit an order, cancel one after the warehouse starts work, correct an inventory count that is wrong, and route a return.
For each step, record what the warehouse system sends back to Shopify, who catches a failed update, and who owns the exception. An exception assigned to everyone is owned by nobody.
Approve the workflow, not the integration label. A good demonstration shows what happens when something breaks, not only when everything works.
How do you evaluate execution and network fit?
Judge the warehouse on the work it performs: receiving, inventory control, picking, packing, returns, and escalation. Ask each candidate to explain its procedures using your order profile, then compare the answers side by side.
Network fit is a separate decision. Compare locations against your customer destinations and inbound routes, and decide whether you need one site or inventory spread across several. More locations create more inventory decisions; a simpler network can still meet your delivery requirements.
Make every service-level commitment measurable: the event that starts the clock, the event that ends it, exclusions, reporting, and who resolves a miss.
How do you compare the full invoice?
A pick-and-pack line is not a quote. Ask each candidate for an itemized invoice illustration against the same operating scenario, built from your actual order activity where possible, with every assumption named.
Keep receiving, storage, pick and pack, materials, returns, account charges, minimums, and warehouse accessorials visible. Identify which charges depend on activity and which apply regardless.
Three billing mechanics deserve a direct answer before signing: how storage space is measured and when, what counts toward the monthly minimum, and what triggers an accessorial charge and who approves it. Keep the fee schedule attached to the agreement, with a defined process for approving changes.
Evaluate transportation separately from warehouse fees. Parcel is one piece; include LTL, FTL, drayage, and crossdock where your inbound or outbound work requires them.
What do you settle before signing?
Settle operating responsibilities, billing definitions, and the exit process before inventory moves. Your agreement should explain inventory reconciliation, open-order handling, data access, final charges, and inventory release.
Keeping transportation contracts in your brand's name keeps that decision separate from warehouse selection, so leaving a warehouse never means leaving your rates.
new3PL is an independent advisory and placement firm that keeps transportation contracts in the brand's name; treat it as one neutral option if you want help separating the two decisions.
FAQ
What should I check first when choosing a 3PL for my Shopify brand?
Start with a written brief of your SKU profile, order workflows, and billing expectations. Ask every warehouse to demonstrate the same work and explain the same invoice.
Do I have to give up my parcel rates when I switch 3PLs?
No. Switching warehouses does not require surrendering rates when transportation contracts stay in your brand's name. Confirm account setup and pickup procedures before inventory moves.
Is a Shopify integration enough to approve a 3PL?
No. Test order edits, cancellations, inventory discrepancies, shipment updates, and returns, and assign an owner to each exception.
