How to Switch Fulfilment Providers Without Disrupting Your Business

Why Businesses Switch Fulfilment Providers

Switching your fulfilment provider is one of the most stressful logistics decisions a business can make. The fear of disruption — missed orders, lost stock, system downtime — keeps many businesses locked into underperforming partnerships far longer than they should be.

But staying with the wrong provider has costs too: declining accuracy, slow dispatch, poor communication, rising prices, and ultimately, unhappy customers.

If you have decided it is time to move, the key is planning the transition carefully so your customers never notice the change.

When It Is Time to Move

Common triggers for switching include:

Declining accuracy — if pick error rates are consistently above 1%, there is a systemic problem
Slow dispatch — orders regularly missing the same-day dispatch window
Poor communication — unanswered emails, no proactive updates, difficulty reaching your account manager
Rising costs — prices increasing without corresponding service improvements
Capacity constraints — your provider cannot accommodate your growth
System limitations — inability to integrate with your sales channels or provide adequate reporting

If you recognise three or more of these issues, it is time to explore alternatives.

The Switching Process: Step by Step

Step 1: Define Your Requirements (Weeks 1–2)

Before approaching new providers, document exactly what you need. This ensures you can compare quotes accurately and avoid repeating the mistakes that led to the switch.

Document:

Current and projected monthly order volumes
SKU count and product characteristics (size, weight, fragility, special handling)
Storage requirements (pallet count, shelf locations)
Integration requirements (Shopify, WooCommerce, Amazon, etc.)
Service level requirements (dispatch cut-off, accuracy targets)
Any special requirements (kitting, branded packaging, B2B distribution)

Step 2: Evaluate and Select a New Provider (Weeks 3–6)

Request detailed quotes from 2–3 potential providers. Evaluate them against your requirements document, not just on price.

Evaluation criteria:

Pricing transparency — itemised rate card, not just a headline per-order rate
Technology — WMS capability, integration support, reporting
Location — proximity to your customer base and supply chain
Scalability — capacity for growth and peak season surges
References — speak to existing clients in similar industries
Site visit — visit the warehouse to assess operations first-hand

Step 3: Plan the Transition (Weeks 7–8)

Once you have selected your new provider, create a detailed transition plan.

Key elements:

Timeline — agree a target go-live date, working backwards to set milestones
Stock transfer method — will you physically move stock from the old warehouse to the new one, or will new supplier deliveries go directly to the new facility while existing stock depletes?
System integration — your new provider needs to connect to your ecommerce platforms. Allow 1–2 weeks for setup and testing.
Parallel running — consider running both providers simultaneously for 1–2 weeks to ensure the new operation is stable before fully cutting over
Communication — notify your customers of any changes to dispatch timelines or tracking providers

Step 4: Prepare the New Facility (Weeks 9–10)

Before any stock arrives, ensure:

Your account is set up in the new provider's WMS
All product data (SKUs, barcodes, descriptions, weights) is loaded into the system
Ecommerce integrations are configured and tested with sample orders
Carrier accounts are set up and labels can be generated
Returns processing procedures are agreed and documented

Step 5: Transfer Stock (Weeks 11–12)

This is the most operationally sensitive phase.

Option A: Direct Transfer

Arrange a haulier to collect all stock from the old warehouse and deliver it to the new facility. This is the fastest method but requires:

Accurate stock counts at both ends
Sufficient receiving capacity at the new warehouse
A brief period (1–3 days) where stock may be in transit and unavailable for orders

Option B: Gradual Migration

Route new supplier deliveries to the new warehouse while allowing existing stock at the old facility to deplete. This avoids the disruption of a physical transfer but means you are running two operations simultaneously for a period.

Option C: Hybrid

Transfer your fast-moving SKUs first, handle orders for those from the new facility, and transfer remaining stock in a second phase.

Step 6: Go Live and Monitor (Weeks 13–14)

Once stock is in the new facility and systems are connected:

Process a batch of test orders through the full cycle
Verify picking accuracy, packing quality, and carrier label generation
Monitor dispatch times against your agreed service levels
Check that tracking information feeds back to your sales channels correctly
Be available to resolve any issues quickly during the first week

Managing the Old Provider

Notice Period

Check your contract for notice period requirements. Most shared warehousing agreements require 1–3 months' notice.

Stock Reconciliation

Before removing stock, conduct a full stock count with your current provider. Any discrepancies should be documented and resolved before transfer.

Final Invoice

Ensure all outstanding charges are settled, including:

Storage up to and including the removal date
Any handling charges for preparing stock for transfer
Management fees for the final period

Data

Request copies of all stock reports, order histories, and returns records. This data belongs to you and will be valuable for your new provider.

Minimising Customer Impact

The goal is for your customers to experience zero disruption.

Best practices:

Build a small buffer stock of your top 20 SKUs to cover any gap during transfer
Time the switch during a quiet trading period (avoid peak season)
Update your returns address on all packaging and your website
Communicate proactively if there will be any temporary changes to dispatch times
