Switching fulfilment providers: 7 signs it's time to make the move

Written by Alice Davies | 15-Dec-2025 08:00:00

The UK eCommerce market gets more competitive by the day. Customers expect more, carriers are placed under more pressure, and peak season gets more unpredictable each passing year.

When fulfilment performance slips during these high-stakes moments, the consequences are immediate: lower conversion rates, higher returns and, most importantly, customers who simply don't come back.

If you've been wondering when the right time is to switch fulfilment provider, you're not alone. Starting this conversation isn't a sign of failure, but a nod to the fact your brand wants fulfilment to be a key part of its growth strategy.

With this in mind, let's explore the warning signs and determine whether it's time for your business to make a change in 2026.

 

A quick rundown: Is it time to switch fulfilment provider?

If you recognise any of the following challenges as your own, it might be time to consider a change.

  • On-time delivery rate (OTD) consistently drops below 95-97%
  • Order accuracy consistently sits under 97-98%
  • Customer complaints linked to fulfilment are increasing
  • Peak season or high demand periods cause operational breakdowns
  • Fulfilment cost per order is rising without explanation
  • You lack real-time visibility on stock levels and order status
  • You don't feel as though your provider sets you up to scale
  • Innovation and automation are nowhere to be seen

If three or more of these apply to your business, it's time to start a dialogue on making a switch.

 

Sign #1: You're missing SLAs and delivery speeds are slipping

UK customers expect fast, accurate, fully tracked delivery. No matter the carrier, they want reliability above all else, and proactive resolution options when things don't go to plan. When orders take longer than promised or you're consistently missing carrier cut-offs, the impact can be severe.

Over eight in ten shoppers (84%) won't return to a brand after one poor delivery experience. One. This statistic alone demonstrates the need for brands to get it right more often than not.

Why this matters

  • Late deliveries are one of the leading causes of negative reviews (93% of consumers read reviews before committing to a purchase)
  • Trust doesn't last long when promises aren't kept
  • Cart abandonment rises when delivery estimates appear unreliable

A fulfilment provider should help you protect delivery promises and have processes in place for when things go wrong.

Red flags

  • Orders are regularly stuck in 'processing'
  • Carrier collections are often missed or inconsistent
  • Longer dispatch windows than competitors

Put simply: if you're constantly having to update customers (or worse, apologise to them), then the issue lies with your fulfilment provider.

 

Sign #2: Order errors, damaged parcels and incorrect shipments are increasing

Mistakes happen. But they shouldn't happen often. UK shoppers have high expectations for accuracy and quality, and one wrong item or damaged parcel can trigger a return, negative review, or a lost customer.

The more this happens, the more your customer service team comes under pressure, and the more likely it becomes that you'll lose customers. According to the UK Institute of Customer Service (ICS) poor customer service is costing businesses £7.3 bn a month in lost productivity. That money is better spent on growing your business, not playing referee between your fulfilment provider and angry customers.


What causes these issues?

  • Poor warehouse management or processes
  • Inexperienced or overstretched staff
  • Lack of validation steps
  • No barcode scanning
  • Inadequate training
  • Poor quality-control processes

What's the impact on your brand's revenue?

  • Reshipment costs
  • Lost inventory value
  • Customer churn
  • Lower lifetime value (LTV)
  • Rising negative reviews

If you're seeing mistakes in this area, your profitability is likely already eroding as a result.

 

Sign #3: Costs are rising without any clear justification

Fulfilment and logistics costs in the UK are on the rise thanks to labour shortages, increased storage demand and carrier price fluctuations. Many brands will have undoubtedly faced fulfilment cost increases in line with these changes; what matters most is transparency.

If you find that your fulfilment costs are increasing without explanation or increases in performance, it could be a telling sign that your provider sees your relationship as purely transactional.

The warning signs

  • Sudden storage surcharges
  • Pick and pack fees creeping upwards
  • Expensive relabelling or returns handling
  • Costs rising faster than order volume

If your fulfilment cost per order or margin is falling without any gains in performance, your provider's pricing model is likely misaligned with your needs.

 

Sign #4: You lack real-time visibility over inventory and orders

Modern eCommerce requires instant information. What's in stock, where it is, and when it'll ship. If your stock requires spreadsheets and guesswork, or you often feel like you're flying blind, you've likely outgrown your current provider.

Successful brands benefit from real-time inventory visibility to analyse stock at any given moment and react to problems quickly, and use demand forecasting tools to avoid under- or over-stocking.


The symptoms of poor visiblity

  • Overselling
  • Stockouts
  • Inaccurate replenishment
  • Unexpected backorders
  • Manual order checks
  • Customer queries your team can't answer

The right provider offers real-time inventory visibility, channel integrations, and no-lag order reporting.

Without visibility, decision-making becomes reactive, stock issues multiply, and your customers start to take notice.

 

Sign #5: Your provider can't scale with you (during peak season or otherwise)

Peak season is a golden opportunity for eCommerce businesses. It’s the time of year when sales are at their highest, and revenue is flowing in. But if your fulfilment provider is missing SLAs during this crucial period, you’re not just losing orders – you’re losing revenue.

The financial impact of missed SLAs can be staggering. In some cases, businesses risk up to 40% of their peak season revenue due to fulfilment issues. That’s a huge chunk of your annual income at stake, simply because your fulfilment provider can't keep up. If your provider isn’t meeting SLAs during the most critical time of year, it’s time to consider a switch.


Scalability failure looks like...

  • Missed carrier cut-offs
  • Slower pick/pack times
  • Labour shortages
  • Storage limits
  • No ability to flex capacity
  • Systems slowing down under load

Your fulfilment provider should help you reach new heights during peak, not collapse under the pressure.

 

Sign #6: Customer complaints about delivery are rising

If your customer support inbox or Trustpilot reviews are filled with delivery complaints, this is a major sign that your provider isn't offering you the support you need.

Bad delivery happens – there's no getting away from it. But your provider should be there for your brand when it does.

Offering customers fast resolution options in the event of bad delivery boosts your chance of preserving loyalty when customer patience is put to the test.

Common delivery complaints

  • "My parcel hasn't arrived on time."
  • "Tracking hasn't updated for days."
  • "I've received the wrong item."
  • "My package arrived damaged."
  • "Nobody can tell me where my order is."

Now, these complains won't all necessarily be the fault of your fulfilment provider, but that's no excuse for burying their heads in the sand. Customer patience is tightening, and delivery is one of the key factors in driving repeat business.

 

Sign #7: Your provider lacks innovation or automation

Effective fulfilment requires efficiency, accuracy and agility. Providers relying on spreadsheets and outdated warehouse systems can't keep pace with eCommerce market growth, stopping the brands they work with from reaching their potential.


Modern providers will offer...

If your provider can't explain their roadmap for automation and visibility improvements, they're planning to fall behind – and they'll take your business with them.

 

What should a best-in-class UK fulfilment provider offer?

Switching fulfilment provider isn't just about putting an end to your problems, but also about unlocking new levels of performance. Here's what a top-class provider can offer:

1. Outstanding service performance

2. Advanced technology

  • Real-time inventory visibility
  • Integrations with Shopify, WooCommerce, Amazon, TikTok Shop and more
  • Clear product roadmap
  • Tools for forecasting and bad delivery scenarios

3. Strong global network

4. Exceptional support

  • Responsive account management or customer service teams
  • Proactivity when issues arise
  • Regular performance reviews
  • Clear SLAs and KPIs

And, last but certainly not least, your fulfilment provider should feel like a partner, not a cost centre.

 

 

How to switch fulfilment providers with minimal disruption

Switching fulfilment providers doesn't need to be complicated. Here's how you can do it without losing your marbles:

Step 1: Audit your current provider

Track or compile key KPIs to benchmark against new partners. Include things like:

  • On-time delivery (OTD)
  • Error rate
  • Inventory/forecasting accuracy


Step 2: Assess potential providers with a checklist

Create a checklist of areas you'd like to improve in or ask potential new partners about.

  • Performance KPIs
  • Technology
  • Onboarding
  • References/case studies
  • Scalability potential
  • Future growth/business goals


Step 3: Create a transition timeline

Once you've found the right fit, plan the following areas as you migrate from one provider to another.

  • Inventory transfer
  • Tech integrations
  • Carrier labels
  • Test orders


Step 4: Communicate and switch

If there's a potential for delays during the changeover, make sure to keep your customers informed.

Phased migrations and dual-run windows can help to avoid order disruption in many cases, but your new provider should handle this in the onboarding process if necessary.

Once you've switched, monitor your KPIs closely for the first 30 days and benchmark against your previous provider.
