Choosing a B2B ecommerce agency means finding a team that understands your products, your operations and the way your customers buy.
For wholesalers, manufacturers and distributors, an online store may need to support negotiated pricing, complex catalogues, credit accounts and repeat orders. It also needs to work with the systems and people already running the business.
An agency’s portfolio can show you its design capabilities. These seven questions will help you assess whether it can deliver what your business needs.
1. Do they understand how your B2B customers buy?
Ask prospective agencies how they would handle your actual sales process.
Your customers might need to see account-specific prices, request a quote, submit a purchase order or pay on agreed terms. Some may require multiple buyers under one company account, with different permissions and approval limits.
A capable agency should ask about these requirements early and explain how they would shape the customer experience.
Ask: “How would you make it easier for an existing trade customer to place their regular order?”
Look for an answer that considers finding products, checking availability, accessing the right pricing and completing the order with minimal effort.
2. How will they connect ecommerce with your existing systems?
Your ecommerce platform needs reliable information about products, customers, stock and orders. Much of that information may already live in your enterprise resource planning (ERP), accounting or warehouse systems.
Ask the agency to explain where each type of information will be managed, how it will move between systems and what happens when an update fails.
Be cautious of a proposal that describes an integration as straightforward before anyone has examined your systems and data.
Ask: “If a customer’s pricing changes in our ERP, how will that change reach the online store—and how will we know if it fails?”
A strong answer should cover both the connection and the ongoing responsibility for keeping it working.
3. How will they decide which platform fits your business?
Ask the agency whether your requirements are better served by adding B2B ordering to your existing website or creating a separate portal, and how that choice affects costs and ongoing management.
An agency should be able to explain its platform recommendation against your requirements.
Ask which capabilities are included as standard, which require additional applications and which need custom development. Those choices affect costs, maintenance and the flexibility to make changes later.
If an agency specialises in one platform, ask it to explain where that platform fits your business well and where compromises would be necessary.
Ask: “Which of our requirements will be hardest to deliver on your recommended platform?”
A useful answer will make the trade-offs clear enough for you to assess.
4. Can they handle your catalogue and pricing complexity?
A polished demonstration using a handful of simple products may tell you little about how your store will work.
Your catalogue might include pack sizes, minimum order quantities, technical specifications, compatible parts or products sold in different units. Pricing could vary by customer, contract, quantity or location.
Give shortlisted agencies a representative sample of your products and pricing rules. Include the awkward exceptions your sales team regularly handles.
Ask: “Can you show us how a customer would find and order these products at the correct price?”
Look for evidence that the proposed approach works for both customers and the staff maintaining the catalogue.
5. How will they help customers and staff adopt the store?
Launch day is one milestone. Customers still need a reason to use the new ordering channel, and your team needs to know how to support it.
Ask how the agency will involve existing customers in testing. It should also consider how sales and customer service staff will introduce the store, help customers get started and handle exceptions.
Useful features might include saved order lists, quick ordering by product code or easy access to previous purchases. Their value depends on how well they match your customers’ routines.
Ask: “What would your plan be for getting our existing trade customers to place their first online order?”
Look for a practical approach to onboarding, training and customer feedback.
6. What is the full cost of delivering and running the solution?
Compare proposals against the same scope. One agency may include data migration, integration testing and training, while another treats them as additional work.
Ask for a breakdown covering:
- Discovery, design and development.
- Product and customer data migration.
- Integrations and third-party applications.
- Platform subscriptions and recurring fees.
- Testing, staff training and launch support.
- Ongoing maintenance and improvements.
Clarify the assumptions behind the quote, including any work your team must complete. Cleaning product data or documenting pricing rules can require substantial internal effort.
Ask: “What could increase the project cost, and which ongoing expenses are excluded from this proposal?”
Where discovery is needed before a firm price can be provided, ask what it will resolve and what deliverables you will receive.
7. What happens after launch?
Before signing, establish who will support the store and how problems will be handled.
Ask about support hours, response commitments, monitoring and responsibility for third-party integrations. Make sure you understand who owns custom code and how your business can access its accounts, documentation and data.
Agree on how you will assess performance after launch. Depending on your priorities, useful measures might include active trade accounts, repeat online orders, ordering errors or time spent manually processing orders.
Ask: “What will you review with us during the first 90 days, and how will you decide what to improve?”
A strong answer should connect ongoing work to the business outcomes you agreed at the start.
A checklist for your shortlist
Before choosing an agency, make sure you have:
- Relevant B2B project examples and references.
- A documented understanding of your buying and sales processes.
- A clear platform recommendation with its limitations explained.
- An integration plan with named responsibilities.
- A scope that accounts for your catalogue and pricing rules.
- A realistic budget, including ongoing costs and internal work.
- An adoption plan and clear post-launch support arrangements.
The right B2B ecommerce agency should help you make informed decisions throughout the project. You should understand what is being built, why it suits your business and what it will take to operate successfully.
