If you’re shipping serious volume on Shopify, handing fulfilment to a Shopify-integrated 3PL usually beats running the warehouse yourself. The hard part is picking the right one. This guide covers what to check, how to compare providers fairly, and how to run the first 90 days so problems surface early.
We’re a Gold Coast 3PL, so we’re one of the options you’d be comparing. We’ve written this so it works for evaluating any provider, us included.
Key takeaways
- Check that the 3PL has a reliable Shopify connection that syncs orders, inventory and tracking automatically, and can handle your expected volume.
- Ask for clear, itemised costs for pick and pack, storage, receiving and returns, modelled against your actual SKU mix.
- Test orders beat sales presentations. Run real orders through your shortlist before you sign.
- Structure the first 90 days around on-time dispatch, pick accuracy, cost per order and stock discrepancies.

Why outsourcing fulfilment makes sense for scaling Shopify stores
Outsourcing starts to make sense once order volume, SKU count or the number of sales channels outgrows what a small team can handle. A 3PL lets you scale fulfilment without building and running your own warehouse. If you’re not sure you’re there yet, here are the signs you need a 3PL partner.
The outcomes to expect from a well-matched 3PL are specific, not vague promises:
- Faster delivery, through carrier networks and a warehouse location that suit where your customers are.
- Fewer picking and packing errors, measured against a stated accuracy target rather than a verbal assurance.
- A clear, itemised cost per order instead of an internal estimate that hides labour and overheads.
- Capacity to absorb peak trading without hiring and training casual staff every November.
Start your budget planning with a per-order estimate from each shortlisted provider, built from your actual SKU mix. Generic price ranges won’t tell you much.
The checklist: five non-negotiables when choosing a Shopify 3PL
Score every candidate against the same five criteria before you sign. Skip one and you risk locking in a provider that can’t keep up with your growth.
Technology fit. The 3PL needs a reliable Shopify connection that sends orders through automatically, updates fulfilment status and keeps inventory in sync. Shopify supports direct 3PL connections through apps and APIs, so there’s no reason to accept manual CSV uploads, which become a real risk as order volume climbs. Our guide to connecting Shopify to a 3PL covers what a good integration looks like.
Operational fit. Ask for a stated pick and pack accuracy target and a same-day dispatch cut-off time. Confirm they handle kitting, bundling and returns in-house rather than passing them on to someone else.
Cost fit. Ask for itemised pricing across pick and pack, storage, receiving and returns, modelled against your own SKU sample. Ask about minimum monthly spends and any other fees up front, so you’re comparing the full cost structure and not just the headline rate.
Coverage. Check that the warehouse location and carrier partners actually suit where your customers live, not just where the 3PL happens to have a lease.
Contract and governance. Insist on a written service level agreement, defined KPIs, clear exit terms and a named contact you can actually reach. These are also the areas where most 3PL red flags show up.
The cheapest pick and pack rate on a proposal can hide extra cost in re-ships, refunds and other fulfilment mistakes. Weight accuracy and integration quality above a slightly cheaper handling fee. Peak season deserves its own questions too: ask for the actual peak volumes they’ve handled and the accuracy they kept up during that period, not a general statement about capacity.
Pro tip: before you sign, ask every shortlisted provider for a written SLA and a sample invoice. Did they hand them over straight away, or did they stall? That tells you more about how they’ll treat you after the contract than anything in the sales deck.
Shortlist, quotes and test orders: a practical selection process
Your complexity and volume decide whether you need a formal request for proposal (RFP) or a tighter shortlist. Brands with large SKU ranges, subscription boxes or international freight usually benefit from a full RFP. Simpler single-channel stores can shortlist two or three providers and move faster.
Ask for a standard pricing sheet. Every provider should return a modelled cost per order based on the same SKU sample, not a price range you can’t compare line by line.
Ask for SLA data and integration details. You want hard dispatch and accuracy numbers and a working integration demo, not a sales deck.
Run test orders end to end. Place real orders through your Shopify store, track them through picking, packing, dispatch and delivery, then process a return the same way.
Plan the timeline realistically. A formal RFP-style switch to a large operator can take a couple of months of implementation and piloting after you’ve chosen a provider. It doesn’t have to. A Shopify brand moving to a smaller, well-integrated 3PL can be live much faster. Ours typically go live in one to two weeks. If a shortlisted provider quotes much longer, ask them why.
Treat the test order phase as non-negotiable. A provider’s sales pitch and its warehouse floor are two different things, and the only way to see the gap is to watch a real order move through their system.
Onboarding and the first 90 days: milestones and metrics
The first three months set the tone for the whole relationship. Plan them deliberately rather than letting them happen to you.
Expect four milestones: systems connect and sync correctly, stock arrives and is received into the warehouse system, a pilot batch of orders runs through picking and dispatch, then you move to full live cutover. Where practical, run a short parallel window so you can catch discrepancies before the new process takes your full order volume. For the detail, see how to onboard a 3PL provider step by step.
Track these metrics daily or weekly through the transition:
- On-time dispatch rate against the agreed cut-off
- Pick accuracy against the SLA target
- Cost per order against your modelled estimate
- Exception rate: stock discrepancies, mis-picks and delayed shipments
Agree who owns what. Your team typically owns Shopify store settings, product data and customer communication. The 3PL typically owns receiving, storage, picking, packing and dispatch. Write the split into the service agreement.

Getting started
If you’re weighing a move, test us the way this guide says to test anyone. Ask for a sample invoice built around your product mix, book a Shopify integration demo, and run a batch of pilot orders through our warehouse. Returns run under the same roof through our shipping and returns service, so you can test those too.
