Switching 3PL Providers, Without the Operational Chaos
Most brands stay with a 3PL that isn't working for them six months longer than they should. Not out of loyalty, but out of fear of the move itself. The good news: switching 3PL providers is almost always less disruptive than staying with one that's holding you back, provided you do it in the right sequence. That sequence is what this page is about.

Your error rate is creeping above 2 percent
Industry benchmark for a healthy 3PL is a 1 to 2 percent error rate, with a documented root-cause process when mistakes happen. Once errors hit 3 percent or higher with no corrective plan, you're not dealing with isolated incidents anymore. You're paying for systemic operational failure in returns, refunds, replacement shipments and customer churn.
SLAs are missed more often than they're hit
Same-day dispatch becomes next-day. Next-day becomes "by end of week". Carrier handoffs drift. The first time it happens at peak, you absorb it. The fifth time, your repeat customer rate starts to drop.
Inventory is lost, damaged or unaccounted for
Phantom stock in the system, damaged goods written off without explanation, cycle counts that never reconcile. Inventory shrinkage is a tax you didn't agree to pay, and a 3PL that can't account for stock at SKU level is failing at the most basic job they were hired to do.
Communication has gone from proactive to non-existent
You stopped getting weekly check-ins. Your account manager changed three times in a year. Tickets sit unanswered for 48 hours. When you can't get a human on the phone during a peak-week problem, the relationship is already broken.
Hidden fees keep showing up on your invoice
Storage surcharges. Receiving fees that weren't in the quote. Carrier fuel adjustments. Long-term storage penalties on slow-moving SKUs. A transparent 3PL bills the same way every month. If your invoice surprises you, your pricing model is the problem.
Their tech can't keep up with your business
No real-time inventory visibility. Integrations that break with every Shopify update. No API for the new sales channel you want to launch. A 3PL with outdated WMS technology becomes a ceiling on how fast you can grow.
They can't scale with your peak or your expansion
Capacity tightens every Q4. They can't take on TikTok Shop, or B2B retail, or a new EU market. Every new initiative needs a phone call, a contract amendment and a delay. Your growth plan is being slowed by your fulfilment partner.
Industry data: 56 percent of consumers will abandon a retailer after a single poor delivery experience. Every week you wait to switch compounds the customer damage you can't see in the dashboard.
How to switch 3PL providers in three phases
Every clean 3PL switch follows the same three-phase framework: prepare, migrate, optimise. The brands that struggle aren't underprepared, they just don't know what to do in what order. Here's the sequence.
Prepare your exit
(2 to 4 weeks)
Before you sign with anyone new, you need three things: your true fulfilment numbers, your contract exit obligations, and a clear specification of what you actually need from a new 3PL provider.
Pull your real cost-per-order from your current 3PL dashboard, broken down by storage, pick and pack, shipping, returns, surcharges and write-offs
Document your operational requirements: SKU count, average daily orders, peak multiplier, integrations, packaging spec, returns rules, international destinations
Read your current contract for notice periods (30, 60 or 90 days are standard), termination fees, data ownership rights and inventory release timing
Define non-negotiables for your next provider (same-day dispatch cut-off, multichannel capability, EU coverage, transparent pricing model, named account manager)
Shortlist providers against those criteria, request quotes, and validate references with brands of similar volume and SKU complexity
Migrate with a parallel-run window
(3 to 5 weeks)
Your customers should not be able to tell this is happening. That is the whole point of a parallel run: test orders first, a staged SKU handover, and a cutover timed to your quietest week.
Build a shared transition document (shared sheet, Asana board or project plan) with every task, owner and deadline visible to both sides
Migrate slow-moving SKUs to the new provider first. Your fast-moving products stay with the incumbent so cash flow is protected while the new 3PL gets up to speed
Integrate your sales channels, OMS and packaging spec with the new provider before any live orders route through them
Run end-to-end test orders: a real order placed on your live site, picked, packed and shipped by the new 3PL, tracked all the way to delivery
Run both providers in parallel for a defined window (typically 2 to 3 weeks), routing a small percentage of orders to the new 3PL and ramping up only when error rates and SLAs hold
Plan inventory cutover for your lowest-volume window, not your peak. End of season, or your quietest trading month, is ideal
Set up returns mail forwarding from your old 3PL with a clear cut-off date, so late returns don't get stranded
Optimise after go-live (first 60 days)
Go-live isn't the finish line. The first 60 days are where a good 3PL provider proves they can actually run your operation better than you had it before.
Daily monitoring of order flow, error rates, dispatch SLA and carrier performance in the first 30 days
Weekly account review with your named onboarding lead to surface friction points before they become habits
Carrier mix optimisation: routing orders through the most efficient carrier for each size, destination and SLA
Packaging efficiency review: box sizing, fill, dim-weight rebalancing
Returns data feedback loop into product, listings and customer service
What changes when you switch to Gonini
Switching 3PL providers is only worth doing if the new one is structurally better. Here's what brands typically gain in the first 90 days with us.
A named onboarding lead, not a ticket queue
Every switch is run by a single named onboarding manager from kickoff to go-live. They own the project plan, the timeline and the daily standups. No generic support email, no rotating account handlers
Transparent per-order pricing, modelled before you commit
We model your fulfilment costs against your current 3PL's actual invoices, not against a generic price list. You see your projected cost-per-order before you sign anything. No hidden surcharges, no minimum spend, no long-term lock-in.
A parallel-run window built into every transition
You don't flip a switch. You ramp. A defined parallel-run period lets us prove our SLAs on a subset of your volume before we take it all. If anything looks wrong, your old 3PL is still shipping, and we fix it before scaling.
Tech that connects in days, not months
Native integrations with Shopify, Shopify Plus, Amazon, eBay, WooCommerce, Magento, BigCommerce, TikTok Shop and 30+ other platforms. Custom OMS integrations available. Most channels live in under 10 minutes of setup.
UK and EU coverage from one account
If part of why you're switching is that your current 3PL can't support EU expansion, you don't need to start a separate provider relationship to fix it. Stock can be held in UK or EU fulfilment centres, or split across both, from the same dashboard.
Operational visibility most brands haven't had before
Live inventory by SKU, order status, dispatch SLA tracking, carrier performance, cost per order, returns data and exception reporting all surfaced in one Seller Portal. The data you wished you'd had with your last 3PL.
Your switching 3PL provider checklist
If you're starting to plan a switch, work through this checklist before you talk to any new provider. It will save you weeks and protect you from the most common transition mistakes.
Before you start the search
Pull 12 months of cost data from your current 3PL invoices
Calculate true cost-per-order including surcharges, returns and write-offs
Document your current error rate, on-time dispatch rate and damaged-goods rate
Review your current contract for notice period, termination fees and data ownership clauses
List your must-haves for the new provider (integrations, geographies, SLAs, pricing model)
During provider selection
Request a fully costed quote based on your actual SKU and order data, not list pricing
Ask for two reference customers of similar volume and category
Confirm the named onboarding lead and ask to meet them before signing
Request a written transition plan with milestones, owners and a go-live date
Confirm contract terms: notice period, termination, data export rights, inventory release
During the transition
Build a shared transition document visible to both 3PL teams
Set up integrations and run end-to-end test orders before any live volume routes through the new 3PL
Migrate slow-moving SKUs first, fast-moving SKUs last
Run a parallel-run window of at least 10 to 14 days
Set a returns mail-forwarding cut-off date with the outgoing 3PL
Communicate any temporary impact to internal teams (CX, marketing, finance)
After go-live
Daily order monitoring for the first 30 days
Weekly account review for the first 60 days
Carrier mix and packaging optimisation review at day 60
Full cost-per-order benchmark vs your previous provider at day 90
Is switching 3PL providers the right move for your business?
Gonini works best for brands that have already outsourced fulfilment once and want a structurally better operator. That includes:
E-commerce brands shipping 1,000 to 50,000+ orders a month who are seeing error rates climb or SLAs slip with their current 3PL
DTC and multichannel sellers whose current 3PL can't keep pace with new sales channels (TikTok Shop, marketplaces, B2B retail)
Brands hitting capacity ceilings at peak season and tired of the Q4 fire drill
UK businesses expanding into the EU who need a single 3PL provider that covers both regions
Operations leaders tired of opaque invoices, hidden surcharges and contracts that auto-renew without warning
Founders who've been quietly thinking about switching 3PL providers for six months and want a structured way to start
