FAQs

  • How do I choose the right 3PL for my supplement business?

    +

    Choosing a third-party logistics (3PL) provider is about much more than finding warehouse space. The right partner should understand the specific requirements of supplement storage, provide complete inventory visibility, maintain recognised food safety standards and be able to support your business as it grows.

    Why this matters

    Your logistics provider becomes an extension of your business. They are responsible for storing your products safely, fulfilling customer orders accurately and protecting your brand's reputation. A warehouse that lacks the appropriate experience, systems or quality controls can lead to delayed deliveries, inventory inaccuracies, damaged products and dissatisfied customers.

    For supplement brands, where product quality, traceability and shelf life are critical, selecting the right logistics partner can make a significant difference to both operational performance and customer confidence.

    What to look for

    When evaluating a 3PL, consider:

    • Experience handling food supplements and nutraceuticals

    • Food-grade warehouse facilities

    • Recognised certifications (such as BRCGS where appropriate)

    • Batch traceability

    • FEFO stock rotation

    • Warehouse Management System with customer visibility

    • Scalability

    • E-commerce fulfilment capability

    • UK and European distribution

    • Value-added services such as contract packing and relabelling

    Common mistakes

    • Choosing purely on price

    • Failing to visit the warehouse

    • Overlooking technology capabilities

    • Ignoring future growth requirements

    • Not checking customer references

    Questions to ask

    • How do you manage batch traceability?

    • What certifications do you hold?

    • How do customers access inventory information?

    • Can you support Amazon FBA?

    • How quickly can you receive imported goods?

    ‍

  • What questions should I ask before appointing a 3PL?

    +

    A good logistics provider should be able to explain not only what services they offer but how they protect your products, maintain compliance and support your future growth.

    Why this matters

    Many businesses compare warehouse costs without understanding how different providers operate. Asking the right questions early can reveal significant differences in quality, technology and operational capability.

    Key questions

    • What industries do you specialise in?

    • Do you regularly handle food supplements?

    • How do you manage expiry dates?

    • What happens if a product recall is required?

    • Can I access live inventory?

    • What KPIs do you measure?

    • How quickly are orders dispatched?

    • Can you integrate with my ERP or website?

    • How do you manage seasonal demand?

    • Can you scale as my business grows?

    Common mistakes

    Focusing only on warehouse rates rather than the total cost of the supply chain.

    ‍

  • Should I choose a specialist supplement 3PL or a general warehouse?

    +

    General warehouses may be suitable for some products, but supplement businesses often benefit from working with a logistics provider that understands food-grade storage, traceability and compliance.

    Why this matters

    Supplements require more than pallet storage.

    Expiry management, hygiene, batch control and environmental monitoring are all important considerations.

    A specialist provider is more likely to have established procedures designed specifically for these requirements.

    Common mistakes

    Assuming every warehouse operates to the same standards.

    ‍

  • How important is warehouse location?

    +

    Warehouse location influences transport costs, delivery times, import efficiency and customer service.

    Why this matters

    Warehouses located close to major ports and transport networks can reduce lead times, minimise transport costs and speed up the movement of imported goods.

    For businesses serving both the UK and Europe, strategic location becomes an important competitive advantage.

    Consider

    • Distance from ports

    • Motorway access

    • Distribution networks

    • Customer locations

    • Future expansion

    ‍

  • Does my 3PL need experience in the supplement industry?

    +

    Industry experience isn't always essential, but it can significantly reduce risk and shorten implementation time.

    Why this matters

    An experienced supplement logistics provider is already familiar with:

    • Batch traceability

    • Shelf life management

    • Food-grade warehousing

    • Retail requirements

    • Amazon FBA

    • Product recalls

    • Customer reporting

    This experience often leads to smoother operations from day one.

    ‍

  • What certifications should I look for in a supplement warehouse?

    +

    The certifications you require will depend on your products, customers and markets, but recognised food safety and quality standards can provide additional assurance that warehouse processes are well controlled.

    Why this matters

    Independent certification demonstrates that a warehouse has been assessed against recognised standards and follows documented procedures for quality, hygiene and operational control.

    Common certifications or approvals that may be relevant include food safety standards, organic certification (where applicable) and customs authorisations for businesses using bonded warehousing or international trade.

    Questions to ask

    • Which certifications do you currently hold?

    • How often are your facilities independently audited?

    • Can you provide copies of your latest certification?

    • What procedures support ongoing compliance?

    Common mistakes

    Assuming certification alone guarantees the right fit. It's also important to understand how those standards are applied day to day and whether they match your specific products and customer requirements.

    ‍

  • Should I visit a warehouse before appointing a 3PL?

    +

    Yes. Whenever possible, visiting a prospective logistics partner gives you valuable insight into their operation and allows you to assess whether their standards match your expectations.

    What to look for

    During your visit, pay attention to:

    • Cleanliness and housekeeping

    • Organisation of storage areas

    • Condition of pallets and racking

    • Staff engagement and professionalism

    • Security measures

    • Technology in use

    • Goods-in and dispatch processes

    A well-run warehouse often reflects a well-run logistics operation.

    Questions to ask

    • Can I see how goods are received?

    • How are customer products segregated?

    • How do you manage damaged stock?

    • How are orders picked and checked before dispatch?

    ‍

  • How do I compare two 3PL providers?

    +

    Comparing logistics providers shouldn't be based on price alone. Consider experience, technology, certifications, service levels, scalability and how well each provider understands your business.

    Compare areas including:

    • Industry experience

    • Food-grade accreditations

    • Warehouse Management System

    • Inventory visibility

    • Customer support

    • Reporting

    • Fulfilment capability

    • Geographic location

    • Growth potential

    Tip

    Create a scorecard and assess each provider against the same criteria rather than relying on instinct.

    ‍

  • Should I ask for customer references?

    +

    Yes. Speaking to existing customers provides valuable insight into how a logistics provider performs in day-to-day operations.

    Ask about

    • Communication

    • Reliability

    • Accuracy

    • Problem solving

    • Responsiveness

    • Reporting

    • Technology

    • Continuous improvement

    ‍

  • What should I look for during a warehouse visit?

    +

    A warehouse visit gives you the opportunity to assess operational standards that may not be visible in a proposal or presentation.

    Observe

    • Cleanliness

    • Housekeeping

    • Staff engagement

    • Product organisation

    • Warehouse condition

    • Security

    • Goods-in processes

    • Dispatch operations

    • Technology

    • Health & Safety

    ‍

  • How often should I review my logistics provider?

    +

    Logistics partnerships should be reviewed regularly to ensure they continue meeting business requirements.

    Typical review topics

    • KPIs

    • Service levels

    • Costs

    • Inventory accuracy

    • Customer feedback

    • New business requirements

    • Continuous improvement opportunities

    Many businesses hold quarterly or biannual review meetings with their logistics partner.

    ‍

  • What does a successful 3PL partnership look like?

    +

    The best logistics relationships are built on trust, transparency and shared objectives.

    A successful 3PL does more than store products and dispatch orders. They become an extension of your business, providing reliable operations, accurate information and practical advice that helps support long-term growth.

    Characteristics of a successful partnership

    • Open communication

    • Shared performance measures

    • Continuous improvement

    • Flexible operations

    • Accurate inventory

    • High order accuracy

    • Reliable reporting

    • Mutual trust

    • Long-term thinking

    Choosing a logistics partner is a strategic decision that can influence customer satisfaction, operational efficiency and future growth for many years.

    Taking the time to evaluate providers carefully, ask the right questions and understand how they operate will help you build a supply chain capable of supporting your business as it evolves.

    The best partnerships are not based solely on cost. They are built on expertise, transparency, shared goals and a commitment to delivering consistently high standards of service.

    ‍

  • How important is warehouse technology?

    +

    Technology underpins almost every aspect of modern logistics.

    Good systems provide

    • Live inventory

    • Barcode scanning

    • Batch traceability

    • Customer portals

    • Automated reporting

    • Integration with business systems

    Technology improves visibility whilst reducing manual administration.

    ‍

  • Should my 3PL integrate with my business systems?

    +

    In most cases, yes. Integrating your Warehouse Management System with your ERP, e-commerce platform or order management system reduces manual administration and improves inventory accuracy.

    Benefits include

    • Live inventory updates

    • Automatic order transfer

    • Faster dispatch

    • Reduced manual errors

    • Better reporting

    • Improved customer experience

    Common integrations

    • Microsoft Dynamics

    • SAP

    • NetSuite

    • Sage

    ‍

  • How important is technology when choosing a 3PL?

    +

    Technology has become one of the biggest differentiators between logistics providers.

    Why this matters

    A modern Warehouse Management System provides:

    • Live inventory

    • Batch tracking

    • Expiry reporting

    • Order tracking

    • Customer dashboards

    • Reporting

    • Integration with e-commerce platforms

    Without these capabilities, businesses often rely on manual processes that increase the risk of errors.

    ‍

  • When is the right time to switch to a third-party logistics provider?

    +

    Many businesses move to a 3PL when their existing operation starts limiting growth. Signs include running out of storage space, struggling to keep up with order volumes or spending too much time managing logistics instead of developing the business.

    Common signs it's time

    • Warehouse space is becoming restricted.

    • Order volumes are increasing rapidly.

    • Stock accuracy is becoming difficult to maintain.

    • Retail customers require more sophisticated fulfilment.

    • You're expanding into new markets.

    • E-commerce sales are growing quickly.

    • Staff are spending too much time on logistics.

    Benefits of outsourcing

    A specialist 3PL can provide additional capacity, experienced warehouse teams, established systems and the flexibility to support future growth without the capital investment of expanding your own facilities.

    ‍

  • How can I tell if a 3PL will scale with my business?

    +

    Your logistics requirements are likely to change as your business grows. Choosing a provider with scalable facilities, systems and services can help avoid the disruption of changing warehouses later.

    Signs of scalability

    • Multiple warehouse locations

    • Additional storage capacity

    • Flexible labour

    • E-commerce capability

    • European distribution

    • Contract packing

    • Amazon preparation

    • Technology integrations

    ‍

  • How do I know if my warehouse is too small?

    +

    If you're regularly running out of storage space, struggling to organise stock or delaying production because there is nowhere to store finished goods, it may be time to review your logistics strategy.

    Warning signs

    • Overflow pallets

    • Narrow aisles

    • Frequent stock movements

    • Temporary storage areas

    • Delayed goods receiving

    • Increasing inventory errors

    • Reduced productivity

    A specialist 3PL can often provide additional capacity without the need for major capital investment.

    ‍

  • Should I outsource fulfilment or keep it in-house?

    +

    The answer depends on your order volumes, available resources and long-term growth plans. Many businesses begin with in-house fulfilment before moving to a specialist provider as demand increases.

    In-house fulfilment may suit

    • Start-up businesses

    • Low order volumes

    • Highly specialised products

    • Businesses wanting complete operational control

    Outsourced fulfilment may suit

    • Rapidly growing brands

    • Multi-channel retailers

    • Amazon sellers

    • Businesses expanding internationally

    • Companies wanting to focus on product development and sales

    Questions to ask yourself

    • Are logistics becoming a distraction from growing the business?

    • Can your current operation cope with seasonal peaks?

    • How much time is spent managing stock and dispatch?

    • Do you have the systems needed to support future growth?

    ‍

  • What happens if my business grows quickly?

    +

    Your logistics provider should be capable of growing alongside your business.

    Look for

    • Additional warehouse capacity

    • Flexible labour

    • Additional fulfilment stations

    • European distribution

    • Technology that supports increased order volumes

    ‍

  • How long does it take to move to a new 3PL?

    +

    Implementation can take anywhere from a few days to several months, depending on the complexity of your operation. Planning and communication are essential to ensure stock transfers and customer deliveries continue with minimal disruption.

    Typical implementation stages

    • Discovery

    • Process mapping

    • System integration

    • Stock transfer

    • User testing

    • Go-live

    • Post-implementation review

    Common mistakes

    Leaving too little time for testing before live operations begin.

    ‍

  • What happens during the onboarding process?

    +

    Onboarding is the process of setting up your products, systems, stock and operating procedures before your logistics provider begins managing day-to-day operations.

    A typical onboarding includes

    • Product information

    • SKU creation

    • Batch requirements

    • Packaging specifications

    • Customer requirements

    • Integration testing

    • Warehouse training

    • Stock migration

    • Trial orders

    A structured onboarding process helps reduce disruption and ensures both parties understand how the operation will work from day one.

    ‍

  • What service levels should I expect from a 3PL?

    +

    A professional 3PL should define clear Service Level Agreements (SLAs) covering order accuracy, dispatch times, inventory accuracy and communication.

    Typical service measures

    • Order accuracy

    • Inventory accuracy

    • Goods receiving times

    • Same-day dispatch cut-off

    • Customer response times

    • Returns processing

    • Stock reporting

    Why this matters

    Clearly defined performance standards allow both parties to measure success and identify opportunities for continuous improvement.

    ‍

  • How important is inventory visibility?

    +

    Complete inventory visibility allows businesses to make informed decisions about purchasing, production and customer service.

    Why this matters

    Without accurate stock information, businesses risk overselling, stock shortages or unnecessary inventory holding.

    A modern customer portal should allow you to see:

    • Stock levels

    • Batch numbers

    • Expiry dates

    • Orders awaiting dispatch

    • Goods received

    • Returns

    • Inventory movements

    ‍

  • Should my 3PL provide regular reporting?

    +

    Yes. Good reporting helps businesses monitor performance, identify trends and make informed supply chain decisions.

    Useful reports include

    • Inventory reports

    • Ageing stock

    • Expiry reports

    • Order volumes

    • Returns

    • Dispatch performance

    • Stock accuracy

    • Warehouse KPIs

    Why this matters

    The best logistics providers don't simply store products—they provide information that helps improve your business.

    ‍

  • What KPIs should I use to measure my 3PL?

    +

    Key Performance Indicators (KPIs) provide an objective way to assess how well your logistics partner is performing.

    Typical KPIs include

    • Order accuracy

    • Inventory accuracy

    • On-time dispatch

    • Goods receiving performance

    • Returns processing

    • Stock discrepancies

    • Customer complaints

    • Picking accuracy

    • Delivery performance

    • Warehouse utilisation

    Common mistake

    Measuring only cost rather than service quality and operational performance.

    ‍

  • How important is communication with my 3PL?

    +

    Strong communication is one of the most overlooked aspects of a successful logistics partnership.

    Good communication includes

    • Regular review meetings

    • Named account contacts

    • Fast response times

    • Performance reporting

    • Early warning of potential issues

    • Continuous improvement discussions

    ‍

  • Should my 3PL offer value-added services?

    +

    Many supplement brands benefit from working with a provider that offers more than storage.

    Examples include

    • Contract packing

    • Kitting

    • Relabelling

    • Promotional packs

    • Amazon preparation

    • Quality inspections

    • Returns management

    Using a single provider often reduces handling and shortens lead times.

    ‍

  • Can my 3PL support seasonal demand?

    +

    Supplement sales often increase significantly during periods such as January, Black Friday and promotional campaigns.

    Ask your provider

    • How do you manage seasonal peaks?

    • Can labour be increased quickly?

    • Is additional warehouse space available?

    • Can dispatch capacity be expanded?

    ‍

  • How secure should my warehouse be?

    +

    Warehouse security protects both your products and your reputation.

    Security measures may include

    • CCTV

    • Controlled access

    • Alarm systems

    • Visitor management

    • Perimeter security

    • Stock audits

    • Cyber security for Warehouse Management Systems

    ‍

  • What happens if something goes wrong?

    +

    Every logistics operation occasionally experiences unexpected challenges. The difference lies in how quickly problems are identified, communicated and resolved.

    Ask

    • How are incidents reported?

    • What happens if stock is damaged?

    • How are customer complaints investigated?

    • How are corrective actions managed?

    ‍

  • How are product recalls managed?

    +

    An experienced 3PL should have documented recall procedures supported by complete batch traceability.

    Effective recall systems include

    • Batch identification

    • Stock isolation

    • Customer reporting

    • Distribution history

    • Regulatory support

    • Investigation records

    ‍

  • Can a 3PL improve customer service?

    +

    Yes. Faster dispatch, better inventory accuracy and improved order tracking all contribute to a better customer experience.

    Benefits include

    • Faster deliveries

    • Fewer picking errors

    • Better communication

    • Reduced stock shortages

    • Improved returns handling

    ‍

  • What are the warning signs of a poor 3PL?

    +

    Several indicators may suggest a logistics provider is not the right fit.

    Warning signs include

    • Poor communication

    • Lack of reporting

    • Limited technology

    • Untidy warehouse

    • High staff turnover

    • Unclear pricing

    • No performance measures

    • Limited industry experience

    • Poor customer references

    ‍

  • How much does a supplement 3PL cost?

    +

    There is no single cost for outsourcing logistics because pricing depends on your products, order volumes, storage requirements and the services you need. Rather than focusing on the lowest warehouse rate, businesses should consider the total cost of ownership, including storage, fulfilment, transport, stock accuracy and customer service.

    Why this matters

    The cheapest provider isn't always the most cost-effective. Hidden costs such as inventory errors, delayed dispatches, damaged products and poor customer service can outweigh any savings on storage charges.

    A transparent pricing model should explain exactly what is included and identify any additional charges for services such as goods receiving, contract packing, Amazon FBA preparation or returns processing.

    What to look for

    • Transparent pricing

    • No unexpected handling charges

    • Clear storage rates

    • Receiving costs

    • Pick and pack charges

    • Returns processing fees

    • Value-added services

    • Transport costs

    Common mistakes

    Comparing quotations without checking exactly what services are included.
