Why do ecommerce brands actually switch 3PLs?

Ecommerce brands rarely begin looking for a new fulfilment partner without cause. Some are leaving an existing provider, and others are outgrowing an in-house operation, but most are doing so under pressure, after months of absorbing a problem that has finally started to cost them revenue.

The underlying issues will be familiar to anyone who has run a warehouse, but what is less visible is how often each one surfaces, and which problems tend to arrive together.

Drawing on 75 conversations we had with ecommerce brands actively searching for a new fulfilment partner, our findings set out why brands begin the search and the pressures behind those decisions, not the state of the wider market.

What the conversations show

• Pricing is consistently the first thing brands raise when asked why they’re looking for a new fulfilment partner.

• Operational and service issues often compound, with communication, billing and visibility problems appearing alongside warehouse performance issues.

• Capability gaps become decisive when a 3PL cannot support requirements such as FBA, returns, kitting or specialist handling.

• Many brands search for a 3PL before they’ve even launched, particularly where existing providers impose minimum volume requirements.

• Switching triggers aren’t always operational: commercial structure, geographic coverage and responsiveness can be just as important.

Immediate reasons for switching 3PL providers

While some issues build gradually, others can trigger a search for a new partner almost immediately. Pricing shocks, serious service failures, and lost inventory are among the problems most likely to push a brand from frustration into action.

Pricing and unexpected costs: Surprise fees, margins added through intermediated models, rising carrier costs or a pricing structure that no longer fits the brand’s unit economics can quickly make an existing arrangement unsustainable. Brands selling subscription boxes and heavy products raise these concerns more often than others.

Service failures and product losses: Lost or mis-shipped inventory, damaged products and returns processes that destroy stock rather than salvage it can quickly erode confidence in a provider. For brands selling high-value SKUs, a single significant loss or fulfilment failure can be enough to trigger a move.

"They recently raised our rates right before peak last year, and we were kind of taken aback. It really has come down to price now because theirs has gone up a lot in the past 12 months." — Collectibles business, USA

Day-to-day friction

Not every reason for switching is a single major failure. Often, smaller operational problems build over time, consuming internal resources and making fulfilment tasks increasingly difficult to manage.

Software, billing and visibility problems: Weak WMS and portal integrations, opaque invoices, no reliable API or Shopify connection. Several brands described auditing bills by hand every week, and losing any reliable view of their own KPIs in the process.

Communications and account management: Slow responses, no dedicated contact, and no escalation path. This matters most on tightly coordinated launches, where a delayed reply results in fulfilment errors.

Capacity, scaling and seasonality: Growth or peak season exposing throughput limits. More than one brand described switching off marketing spend because the warehouse couldn’t keep up with demand.

Reporting and carrier performance visibility: Carrier performance data and transparent SLAs are increasingly expected as standard. Brands move when they can’t get either.

"I'm not saying never audit [your bills], I'm just saying it's cumbersome and it shouldn't be. I shouldn't be auditing my invoices for four hours a week. It's absolutely exhausting." — Homeware brand, USA

Where capability runs out

For some brands, the issue isn’t how well a 3PL performs, but whether it can support the operation at all. When a provider can’t handle a required workflow, product type or regulatory requirement, there’s often little room for compromise.

Returns, rework and complex workflows: Inspection, refurbishment, serialisation, kitting, hygienic liner replacement, and FBA prep. When the process can’t be replicated, brands often switch providers.

FBA and marketplace readiness: For brands selling through marketplaces, fulfilment requirements can be highly specific. Opaque or uncompetitive prep pricing, or FBA treated as an afterthought rather than a core workflow, can become a reason to look elsewhere.

Product and regulatory specialism: Requirements such as hazardous goods handling, chilled storage, GDP or FDA compliance and serialisation can rule out otherwise suitable providers. For brands with specialist requirements, these capabilities are often non-negotiable.

"The cost of production is around 60% of the sales price. We can't afford a refund or return just because of a damaged book. Shipping has to be carried out by someone who knows what they're doing; minimising damages by handling with care." — Luxury publishing business, UAE

Commercial fit goes beyond the warehouse

Not every search begins with a fulfilment failure. For some brands, the issue is simply fit: minimum volumes, geographic coverage or a commercial model that no longer works.

Minimums and commercial flexibility: Startups and small launches turned down for not meeting volume thresholds. A one to two pallet launch is a common profile among brands rejected by other fulfilment providers.

Geographic coverage, tariffs and localisation: International brands moving stock in-country to cut duties and transit times, particularly on UK to US, and EU to UK routes.

Direct control and a simpler commercial model: A preference for dealing with the warehouse directly, without layers that add cost and distance from the operation.

"We need a 3PL that accepts low volumes at the beginning and lets us scale step by step. We'd already been turned away by one for not meeting their 2,000-shipment minimum." — Health and wellness brand, USA

Reasons compound until breaking point

Brands rarely leave over a single issue. In most cases, several of the pressures above compound until the situation becomes urgent, whether that is lost sales, a failed peak, a significant error, or an unsustainable cost.

"You know when your 3PL starts growing and getting more customers, and they start making a lot of mistakes and you just don't see the end of it?" — eCommerce toy brand, UK

What this suggests about 3PL partnerships

Across the conversations, many of the problems appear to begin before the 3PL relationship does. The issue is often not simply that a provider performs poorly over time, but that the original match was wrong from the start. 

A brand leaving over pricing structure needs a different conversation to one leaving over a returns workflow that destroyed stock. A brand rejected elsewhere for a two pallet launch needs a third. As generic enquiries, all three look alike. Only the reason behind the search tells them apart. The same reasons also recur. Pricing pressure, capacity constraints and capability gaps are not events but conditions. They build over the life of any fulfilment relationship, and whether they end the next one appears to depend on how much operational fit existed at the start.

“Brands don’t switch fulfilment partners lightly. By the time they start looking, something has usually been going wrong for a while. What stands out is how often the deciding factor sits outside the warehouse itself. Pricing structure, billing clarity and responsiveness come up as frequently as operational performance, which suggests the way a relationship is set up matters as much as how it is run.” — James Olsen, CEO, fulfilment.com

Scrutiny, however, is concentrated in a particular place. Pricing transparency, billing accuracy and responsiveness account for a substantial share of everything cited, and none of the three is a direct warehouse operation. The rarer reasons work differently. A provider that can't legally handle hazardous goods, or hold stock at a specific temperature, isn't a partial fit for those brands, and no amount of service quality elsewhere closes that gap.

How we can help

Every reason above points to the same underlying issue: the match was wrong before the relationship started. That's the part we work on.

When you come to us, we ask why you're looking, not just what you need. For example, a brand leaving over surprise fees needs a different shortlist to one leaving over a returns process that wrote off good stock. We use the reason behind your search to filter the 200+ vetted 3PLs in our network, so you're only comparing providers who can actually take you on.

That means:

• Pricing you can check before you commit: We put comparable quotes side by side, so you can see the fee structure rather than discovering it on your first invoice.
  
  

• Capability confirmed upfront: If you need FBA prep, kitting, hazardous goods handling, chilled storage, or GDP and FDA compliance, we only shortlist providers who genuinely do it, not ones who'll treat it as an afterthought.
  
  

• No minimum volume dead ends: Our network includes providers who take on one to two pallet launches, so an early-stage brand isn't ruled out before the conversation starts.
  
  

• Coverage where your customers are: Whether you're moving stock in-country to cut duties on UK to US routes or expanding across the EU, we match you with providers who already operate there.
  
  

• Direct relationships: You deal with the warehouse, without layers in between adding cost and distance from your operation.

Comparing fulfilment providers costs nothing. Tell us what went wrong last time and we'll shortlist partners built for your requirements, in minutes.
