How to Brief a 3PL Provider: What Information You Need to Have Ready

Briefing a 3PL provider properly is one of the easiest ways to get a faster quote, avoid hidden assumptions and make the move into outsourced logistics smoother.

Many businesses approach 3PL logistics with a simple question: "How much will it cost to store and send our stock?" That is a fair starting point, but a provider cannot answer accurately without understanding how your products move, how orders are placed, what customers expect, and where the tricky parts of the operation sit.

A strong brief does not need to be a polished document. It can be a spreadsheet, an email summary or a structured call. What matters is that it gives the provider enough detail to assess fit, plan capacity and price the work sensibly.

Below is a practical guide to the information you should have ready before speaking to a 3PL provider.

Why a clear 3PL brief matters

A 3PL provider is not just quoting for warehouse space. They are assessing the labour, systems, equipment, transport and processes needed to handle your stock correctly.

If your brief is vague, the provider has to make assumptions. Those assumptions can lead to inaccurate pricing, missed operational details and delays during onboarding. If your brief is clear, the provider can ask better questions, flag risks early and build a service around the way your business actually works.

A good brief helps with:

• Faster and more accurate quotes
• Better advice on service fit
• Clearer onboarding timelines
• Fewer surprises around costs
• A smoother handover from your current process
• More realistic expectations on cut-off times, delivery options and stock control

For growing businesses, this is especially important. The point of outsourcing is usually to create more time, capacity and reliability. Starting with the right information makes that far easier.

Start with what you need the 3PL to do

Before getting into SKU counts and pallet numbers, be clear on the outcome you want.

Some businesses need a full pick, pack and dispatch operation. Others need overflow warehousing, bulk pallet storage, same-day transport, retail display assembly or a combination of services. Your provider needs to know which parts of the logistics process you want to outsource and which parts you plan to keep in-house.

For example, an eCommerce brand may need a complete order fulfilment service covering goods in, storage, pick and pack, carrier dispatch and returns. A manufacturer may only need extra pallet and bulk storage for seasonal stock. A retail supplier may need display units assembled, pre-filled and distributed to stores.

Your opening summary should answer three questions clearly:

• What do you sell?
• What logistics problem are you trying to solve?
• What would a successful partnership look like in 3 to 6 months?

This gives the provider the context behind the numbers.

Company and product background

A short business overview helps the 3PL understand the shape of your operation. This does not need to be a long company history. Focus on the practical details that affect logistics.

Include your business type, sales channels and product categories. If you sell through your own website, online marketplaces, wholesale, retailers or trade customers, say so. Different sales channels often come with different requirements around packaging, labelling, service levels and returns.

You should also explain the type of products you handle. Are they fragile, heavy, high value, food related, batch controlled, promotional, seasonal or awkward to store? Do they have best-before dates, serial numbers or special handling needs? These details affect storage layout, picking checks, stock rotation and carrier choice.

If you already know your main pain points, be honest about them. Common examples include late dispatches, lack of warehouse space, stock errors, rising carrier costs, too much time spent packing orders, or difficulty coping with peak periods. A good provider will not see this as a weakness. They need to know where the pressure is so they can design the right process.

Stock and storage information to prepare

Storage is one of the biggest areas where detail matters. A provider needs to understand not just how much stock you have now, but how that stock arrives, how quickly it moves and how it needs to be controlled.

At minimum, prepare your number of SKUs, approximate stock holding, pallet quantities and product dimensions where available. If you have a product list or stock file, this is often the most useful document you can share.

Useful storage details include:

• Number of active SKUs
• Average units held per SKU
• Pallet quantities and pallet type
• Carton dimensions and weights
• Product dimensions and weights
• Whether stock is racked, floor stored or mixed
• Batch, serial number or best-before date requirements
• Stock rotation method, such as FIFO or FEFO
• Seasonal stock increases
• Any stock that needs segregation or special handling

You do not need perfect data to start a conversation. If you are unsure, say which figures are estimates. A reliable provider can work with estimates at first, then firm up pricing and space planning once stock files or sample data are available.

Order volumes and fulfilment requirements

Order volume is one of the main factors in any 3PL logistics brief. A provider needs to know how many orders they will handle, how complex those orders are and what customers expect after checkout.

Average daily order numbers are useful, but they do not tell the whole story. Peaks matter. If you usually send 80 orders per day but reach 500 orders per day during Black Friday, Christmas or a product launch, the provider needs to know that from the start.

Share information such as average orders per day, peak orders per day, average order lines, average units per order and the proportion of single-item versus multi-item orders. Also explain your dispatch promise. Do you offer next-day delivery? Do orders need to be dispatched the same day if placed before a certain time? Do wholesale orders follow a different process from direct-to-consumer orders?

Packaging is another important detail. Let the provider know whether you use plain cartons, branded packaging, padded mailers, fragile protection, inserts, gift notes or specific packing rules. If your brand experience depends on how an order is packed, include photos, packing instructions or examples.

Returns should be included too. Even if returns are low, the provider needs to know whether returned items are inspected, quarantined, reworked, restocked or disposed of.

Inbound stock and supplier details

Goods in is often overlooked in a 3PL brief, but it can have a major impact on warehouse planning. The provider needs to understand how stock arrives before they can plan how it will be checked, booked in and stored.

Explain whether stock arrives from UK suppliers, manufacturers, import containers, couriers, pallet networks or your own vehicles. Include typical delivery frequency, notice periods and whether deliveries arrive palletised, loose loaded or mixed by SKU.

If stock arrives in containers, say whether it is floor loaded or palletised, and whether carton counts and SKU checks are required during unloading. If stock arrives with incomplete paperwork or mixed SKUs, mention this early. It may not be a problem, but it will affect the process.

You should also prepare examples of delivery notes, packing lists, commercial invoices or supplier ASN files if you use them. The cleaner the inbound information, the easier it is for a 3PL to keep stock accurate from day one.

Delivery and transport requirements

Your 3PL provider also needs to understand how goods leave the warehouse. Parcel dispatch, pallet distribution, dedicated vehicles and retail deliveries all work differently.

For eCommerce orders, share your current carrier services, delivery countries, delivery speeds and any issues you are experiencing. For trade or wholesale orders, explain pallet sizes, booking-in requirements, tail-lift needs, timed delivery windows and whether customers require specific paperwork.

If you need dedicated vehicles, urgent movements or store deliveries, include those details in your brief. Businesses with more complex transport and delivery requirements should be clear about vehicle type, loading access, delivery restrictions and whether proof of delivery is needed.

Do not forget failed deliveries and exceptions. How should the provider handle returned parcels, refused pallets, damaged goods or delivery address errors? These situations are easier to manage when the rules are agreed in advance.

Systems, integrations and data

Systems are central to a successful 3PL partnership. Even if your products are simple, order data, stock movements and dispatch confirmations need to flow accurately.

Prepare a list of the platforms you use. This might include your website platform, marketplace accounts, ERP, inventory system, accounting software or shipping tools. If you sell through multiple channels, explain which system is the source of truth for stock and orders.

For eCommerce fulfilment, the provider will usually need product data, order data and stock data. They may also need access to a test store, API credentials or export files depending on the integration method.

Useful system information includes:

• Sales platforms and marketplaces
• Order management system or ERP
• Product codes, SKUs and barcodes
• Product descriptions and variant details
• Stock file format
• Order import method
• Dispatch confirmation requirements
• Tracking number upload requirements
• Returns data requirements

If your product data is messy, now is the time to clean it. Duplicate SKUs, missing barcodes and inconsistent product names can all create avoidable issues during onboarding.

Special projects, FSDUs and co-packing

Not every 3PL brief is about standard storage and dispatch. Many product businesses also need project work, such as re-packing, point of sale assembly, retail display preparation or promotional fulfilment.

If you need FSDU design, pre-fill and dispatch, your brief should include the display type, unit dimensions, product quantities per display, retailer requirements, artwork or assembly instructions, delivery schedule and any compliance documents. Retail projects often involve strict timings, so deadlines and approval stages should be clear from the start.

For co-packing or contract packing, include sample photos, packing specifications, expected volumes, quality checks and whether materials are supplied by you or sourced by the provider. Small details matter here. For example, the difference between adding one insert to a carton and building a multi-product promotional kit can change the labour requirement significantly.

A simple 3PL briefing checklist

If you are not sure where to start, use the table below as a working checklist. You can copy the headings into a document or spreadsheet and fill in what you know.

You do not have to complete every section before making contact. However, the more detail you can provide, the more useful the first conversation will be.

Information that affects pricing

A 3PL quote is usually built from several moving parts. Storage, goods in, picking, packing, packaging materials, carrier charges, returns, integrations and special projects can all affect the final cost.

The most common pricing problems happen when the brief leaves out operational complexity. For example, 1,000 orders per month sounds straightforward, but the cost will differ depending on whether those orders are single-item parcels, multi-line orders, fragile goods, subscription kits or wholesale cartons.

Be clear about anything that adds handling time. This includes bundling, re-labelling, expiry date checks, serial number capture, custom packaging, quality control, retailer paperwork and customer-specific delivery rules.

It is also worth explaining what you currently spend if you know it. You do not have to reveal every commercial detail, but sharing your current pain points around cost helps the provider suggest a realistic setup.

Common mistakes when briefing a 3PL provider

The biggest mistake is only sharing average volumes. Averages hide peaks, and peaks are often where logistics operations fail. If your business has big campaign days, seasonal surges or retailer deadlines, make them clear.

Another common mistake is underestimating process detail. Business owners often know the quirks of their operation so well that they forget to mention them. If your team follows a special packing rule, checks a product before dispatch or adds paperwork for certain customers, that rule needs to be documented.

It is also risky to brief purely on price. Price matters, but the cheapest quote is not always the best fit if it misses service requirements. A good briefing process should help you compare providers on capability, communication and reliability as well as cost.

Finally, avoid waiting until the last minute. Moving stock, integrating systems and testing processes all take time. If you are planning to outsource before a peak period, product launch or retail promotion, start the conversation as early as possible.

What a good provider should do with your brief

Once you have shared your brief, the provider should not simply send a generic price list. They should review the details, ask practical questions and explain how they would handle your operation.

You should expect discussion around stock layout, order workflow, integration options, carrier services, reporting, responsibilities and onboarding. If something in your brief creates a risk, such as missing barcodes or uncertain peak volumes, a good provider should flag it early.

The next step is usually a quote, followed by a more detailed onboarding plan if both sides agree there is a fit. That plan should clarify timelines, data requirements, stock transfer arrangements, testing and go-live responsibilities.
