The eight things peak will tell you about your 3PL that a rate card never will

A 3PL rate card gives you the cost of individual fulfilment activities; peak shows you how well those activities work together when volumes, customer expectations and operational pressure are at their highest, revealing the planning, resilience, visibility and problem-solving capability that a spreadsheet rarely captures.

Key takeaways

• Peak exposes operational resilience, not just warehouse capacity. A 3PL that looks efficient at average volumes may struggle when order velocity suddenly changes.

• The best 3PLs plan with you. Forecasting, capacity planning and clear communication should happen before Black Friday, not after something goes wrong.

• Technology matters most when things get complicated. Real-time visibility becomes significantly more valuable when inventory, orders and exceptions are moving quickly.

• Fulfilment doesn't end at dispatch. Carrier performance, delivery exceptions, returns and customer service all form part of the experience your 3PL is helping you deliver.

• The real question after peak isn't “did you hit your numbers?” but “what did you learn, and what will you change as a result?”

Why peak is a better 3PL test than a rate card

A rate card tells you what a 3PL charges for receiving, storage, pick and pack, shipping, returns and any value-added services.

Useful? Absolutely.

Enough to understand how that 3PL will perform when your order volume doubles? Not necessarily.

The problem is that fulfilment costs rarely exist in isolation. A cheaper pick fee means very little if poor inventory accuracy creates overselling, manual processes slow down dispatch, or your customer service team spends December answering “where is my order?” tickets.

Peak has a habit of exposing those hidden costs.

Order volumes become less predictable. Promotions create sudden surges. Bestsellers move faster than forecast. Returns arrive in waves. Carrier networks become congested. Marketing, operations, finance and customer service all need the same information at the same time.

Peak changes the question from “can this 3PL process our normal volume?”, to “can this 3PL remain reliable when nothing is normal?”. That is a much better test of operational maturity.

At IFGlobal, we see peak as an annual stress test of the entire fulfilment model. Our experience of Peak 2025 reinforced that view.

• 20% more orders dispatched than the previous year

• 97% SLA adherence

The result wasn't simply a bigger warehouse effort; it came from earlier forecasting, operational planning, workflow optimisation, carrier collaboration and real-time visibility all working together.

If you're reviewing your 3PL ahead of peak, here are eight things worth looking at.

1. How well your 3PL plans ahead

Anyone can tell you they have capacity. But how do they prove it?

Peak planning should start months before the first Black Friday order lands. Your 3PL should want to understand your promotional calendar, expected order volumes, SKU velocity, new product launches, channel mix, packaging requirements and international demand.

They should also be challenging your assumptions.

A forecast that says “we expect 40,000 orders” is useful. A conversation that asks when those orders will arrive, which SKUs will drive them, how promotional activity will affect the curve and what happens if volume is 30% higher than expected is much more valuable.

At IFGlobal, we typically recommend beginning peak planning 12–16 weeks before Black Friday, depending on SKU breadth, lead times and channel complexity.

Questions to ask your 3PL

• When does your formal peak planning process begin?

• What information do you need from us?

• How do you build capacity around our forecast?

• What happens if our forecast changes?

• How do you scenario-plan for a volume spike?

• Who owns the peak plan on your side?

A mature partner should be helping you identify the problem before it happens.

2. Whether “scalable” really means scalable

“Scalable” is one of the most overused words in fulfilment.

A warehouse can have plenty of floor space and still struggle to scale. True scalability means being able to increase throughput without allowing accuracy, service levels or communication to fall apart.

That means having a plan for:

• Additional labour

• Packing and dispatch stations

• Shifts and operating hours

• Packaging materials

• Inventory replenishment

• Carrier collections

• Systems capacity

• Quality control

• Exceptions and rework

Peak is where these individual components collide.

IFGlobal's 2024 peak provides a useful example. We handled 52% more orders picked, packed and dispatched over Black Friday weekend than the previous year, while overall order volume increased by 28.7% between 1st November 2024 and 10th January 2025.

The important point isn't the number itself, but what that number tells you. Capacity needs to be designed, not assumed.

Don't just ask a 3PL, “can you handle our peak volume?”. Ask them to show you what changes operationally when your volume goes from 2,000 orders a day to 5,000. The answer should go beyond “we'll put more people on the floor.”

3. Whether their technology helps when things get messy

Technology is easy to demonstrate when everything is working normally. Peak is when you find out whether it helps.

A dashboard showing yesterday's order volume isn't particularly transformational. Useful technology should give teams the information and tools they need to make decisions while there is still time to act, stopping a small issue from becoming a customer-facing problem.

If 500 orders suddenly become stuck because of an integration issue, a report telling you about it tomorrow isn't much use. Visibility that flags the problem while there is still time to intervene is considerably more valuable.

At IFGlobal, our proprietary Fulfilment Operating System, BladePRO, provides real-time visibility across inventory and order flow, automated workflows and performance reporting across the entire fulfilment operation. During peak, that visibility helps teams make faster decisions and dynamically rebalance workloads.

The point isn't to have the most impressive technology stack. It's to have technology that helps you make better decisions when things get complicated.

4. How good their communication really is

You don't need a 3PL that tells you everything. You need one that tells you the right thing at the right time.

During peak, communication becomes part of the operational infrastructure.

If a carrier changes its collection schedule, a forecast jumps significantly, a particular SKU is running low or a dispatch SLA is at risk, your team needs to know what is happening and what action is required.

Good communication should be proactive rather than reactive.

Your 3PL should be able to tell you:

• What your peak cut-offs are

• When capacity checkpoints will happen

• How volume changes will be communicated

• What happens when an SLA is at risk

• Who owns escalation

• How carrier disruption will be communicated

• How post-peak performance will be reviewed

At IFGlobal, peak planning is supported by a centralised Peak Readiness Guide and regular operational communications through our Account Management team, Client Portal and email notifications, giving brands a single source of truth for key dates, cut-offs and actions.

Because when your fulfilment partner goes quiet, your customer service team usually gets louder.

“Peak is where a 3PL proves whether it’s really a partner. Anyone can promise capacity when volumes are predictable; the real test is how you communicate and adapt when they aren’t. For us, the value comes from working with brands early, challenging assumptions and solving problems together so peak becomes something we’re prepared for rather than something we have to firefight.” Dom Webb, Account Management Lead, IFGlobal.

5. What happens when the carrier isn't playing ball

Your 3PL doesn't control the entire delivery network. That's precisely why you should ask what happens when something goes wrong outside the warehouse.

Peak puts pressure on carrier networks. Capacity constraints, weather, depot disruption, network congestion and unexpected demand can all affect delivery performance.

A strong 3PL should therefore have more than a list of carrier rates. It should have carrier strategy.

That might include:

• Multiple carrier options

• Defined service levels

• Contingency plans

• Escalation routes

• Carrier performance monitoring

• The ability to redirect volume where appropriate

For brands selling internationally, network design matters too. Strategically positioned inventory can reduce delivery distances and create more options when one region or carrier network experiences disruption.

IFGlobal operates fulfilment centres across the UK, EU and US, giving brands the option to position inventory closer to customers and build a more geographically resilient operation.

A carrier price isn't a resilience strategy. Ask what your 3PL does when the cheapest or preferred option stops performing.

6. Whether they protect accuracy when speed increases

Peak often creates an uncomfortable trade-off.

• Move faster and the risk of mistakes can increase

• Slow down to protect accuracy and you risk missing service levels

The best fulfilment operations are designed so that speed and accuracy aren't competing priorities. That comes down to process design, technology, quality controls, fulfilment centre layout, training, and the ability to identify exceptions early.

It's also why headline throughput figures should always be paired with accuracy and SLA data.

Ask your 3PL for:

• Order accuracy

• Pick accuracy

• Dispatch SLA adherence

• Inventory accuracy

• Exception rates

• Returns accuracy

• Peak performance versus business-as-usual performance

Here at IFGlobal, we report 99.98% order accuracy and 99.9% on-time dispatch across our operation. Our quality management approach is also supported by ISO 9001 certification, which provides a structured framework for monitoring and continuously improving quality.

The point isn't to chase a perfect-looking number, but to understand how your 3PL maintains quality when pressure increases.

7. What happens after the order leaves the warehouse

Here's another thing a rate card can hide. Fulfilment doesn't end when the parcel leaves the building. Peak creates a second operational wave after dispatch.

Customers contact your team about delayed deliveries. Parcels are returned. Refunds need processing. Exchanges need managing. Returned stock needs checking back into inventory.

If your 3PL treats returns as an afterthought, the pressure moves downstream into your customer service and finance teams. That's why peak performance should be measured across the entire customer journey.

This also gives you a better way to assess the real cost of fulfilment.

A 3PL with a slightly higher pick fee but substantially fewer delivery exceptions, manual interventions and return-processing delays may be delivering better overall value.

A good peak review therefore shouldn't finish with “all orders dispatched”. It should ask what happened to those orders afterwards.

8. What your 3PL learns and whether it changes anything

This may be the most revealing test of all.

Every peak produces data, but not every 3PL turns that data into improvement. A genuinely mature partner should finish peak with a list of lessons, not just a spreadsheet of results.

• What caused the biggest bottlenecks?

• Which processes worked particularly well?

• Where did demand differ from forecast?

• Which carriers performed best?

• Which SKUs created operational friction?

• Did any packaging or kitting processes slow throughput?

• Where could inventory have been positioned differently?

• Which issues were avoidable?

• And crucially: what will change before next peak?

If your 3PL's post-peak review simply confirms that it hit its SLAs, you've learned something about last year's performance.

If it identifies why performance looked the way it did and what will be different next time, you've learned something about the maturity of the operation.

At IFGlobal, peak performance feeds into ongoing operational planning, including improvements around forecasting, flexible labour, workflows, carrier resilience and earlier preparation. That's the difference between reporting performance and improving performance.

The peak test: Key questions to ask your 3PL

If you're reviewing your current provider or comparing potential partners, use these key questions as a starting point.

If the answers are specific, measurable and backed by examples, you're starting to see the operation behind the sales pitch.  If the answers are vague, that's useful information too!

“The real commercial cost of fulfilment isn't always visible on a rate card. If an operation can't flex with demand, the impact can quickly show up in missed sales, additional customer service costs, inventory issues and a poor customer experience. Peak gives brands the opportunity to look beyond the headline price and assess whether their fulfilment model is giving them the flexibility and operational capability they need to grow.” Dan Thompson, Commercial Manager, IFGlobal.

How to benchmark your 3PL during peak

You don't have to wait until the end of peak to decide whether your 3PL performed well. Set your baseline before the season starts and review performance at agreed checkpoints.

Before peak

Record:

• Forecasted versus expected order volume

• Normal order accuracy

• Normal dispatch SLA

• Inventory accuracy

• Normal returns processing time

• Carrier performance

• Known operational constraints

During peak

Track:

• Actual versus forecast volume

• Orders processed per day

• SLA performance

• Accuracy

• Exceptions

• Carrier performance

• Backlog

• Customer service contacts

• Returns volumes

After peak

Ask what changed.

Compare your peak results with business-as-usual performance.

A provider doesn't necessarily fail because one KPI dips during the busiest week of the year. What matters is whether the impact was understood, communicated and controlled, and whether the same issue is likely to happen again.

That context is much more useful than a single headline number.

Don't choose a 3PL on the rate card alone

Price matters, but fulfilment is one of those areas where the cheapest line item can become the most expensive decision if it creates hidden operational costs elsewhere in the business.

A slightly lower pick fee won't compensate for:

• Stock inaccuracies

• Missed dispatch SLAs

• Additional customer service contacts

• Emergency carrier changes

• Manual reconciliation

• Slow returns

• Lost sales caused by poor inventory visibility

• Operational teams spending their time firefighting

It’s worth changing the mindset behind selecting a fulfilment partner from “which has the cheapest rate card?” to “which gives us the strongest operational performance for the total cost of serving our customers?"

That is a much harder question to answer from a spreadsheet.

Fortunately, peak gives you another way to answer it.

Look at how a provider plans, responds, and communicates. Look at its data, accuracy, and carrier strategy. Look at what happens when something goes wrong, then look at what it changes afterwards.

Anyone can look good on a rate card. Peak shows you what you're buying.

Fulfilment that performs when it matters

At IFGlobal, we don't see peak as an isolated season. It's a test of whether the fulfilment model is genuinely built to support growth throughout the year.

We've been helping ecommerce brands scale since 2002, shipping products across 100+ countries. Today, our UK, EU and US fulfilment network is supported by BladePRO, our proprietary Fulfilment Operating System, giving brands visibility across orders, inventory and operational performance.

Our approach is built around the idea that fulfilment should evolve with the business, not become a constraint as it grows.

That means combining people, processes, technology and infrastructure to create an operation that can absorb complexity, adapt to demand and keep customer experience at the centre.

Planning your next move?

Peak isn't necessarily the right time to change 3PLs. Switching fulfilment providers immediately before your busiest trading period can introduce its own operational risks.

But it is a good time to understand how your current operation is performing and whether it will still support where your business is heading next.

If you're reviewing your fulfilment model, we're happy to have an early conversation, benchmark what you're doing today and explore what a future move could look like, without any expectation to switch before peak.

Because the best time to assess whether your 3PL can handle your next stage of growth is before you need them to prove it.
