THE KEY ANSWER
The first version of the B2B platform should handle the full, most common purchase scenario. The priority is correct prices, availability, roles, the order, and its status. Add advanced features only after verifying customer behavior.
Start with conversations about the last order
Ask customers to describe a specific purchase: where they got the product number, how they checked the price, and what they had to ask about. Observe the documents and tools used between steps. The question “what features should the portal have?” usually leads to a long wish list. The last actual transaction shows what hinders work.
Distinguish segments. A regular customer ordering the same items needs a quick reorder, while a new customer needs better descriptions and help with selection. The first version can handle one of these scenarios. A conscious choice of the group makes it easier to limit the scope without creating a portal that tries to be everything for everyone.

Data must align with the sales process
Individual price lists, discounts, packaging units, and limits are part of the purchase. If the portal shows an indicative price, but the real one comes back via email, the customer still has to take an extra step. Determine which terms can be presented as binding and which require confirmation. Mark this clearly before placing the order.
Availability should have a defined meaning: stock status, reservation possibility, or expected date. Do not use these terms interchangeably. If data is updated periodically, show the update time and plan a check before approval. An error in the delivery promise may cost more than a few extra seconds of checking.
Serve the company, not just a single account
One person may prepare the purchase, while another approves it. Accounting receives the invoice, and the warehouse handles delivery. Map roles and addresses without assuming that the account owner does everything. The user should see the appropriate orders and understand when a supervisor's approval is needed.
Prepare full error handling: changed price, missing item, exceeded limit, and duplicate submission. Keep the cart and allow fixing the specific issue. A generic “an error occurred” message often ends with a call to the sales representative. This restores the work that the portal was meant to reduce and weakens trust in the next purchase.
Measure autonomy and service quality
After launch, monitor completed orders, status inquiries, and cases of returning to email. Separate invited customers from actively purchasing ones. If orders still require manual correction in the ERP, check the integration and rules before expanding the catalog with AI recommendations.
Choose subsequent features based on process obstacles. This could be importing a product list, reordering, or tracking delivery. An assistant can help find a product in the catalog, but it will not replace correct prices and data. First ensure a reliable purchase, and then shorten the path to it.
WHERE TO START
Bring this into your project.
- Choose the customer group and order type.
- Agree on the meaning of prices, stock levels, and deadlines.
- Plan roles and purchase approval.
- Measure manual interventions after placing an order.
Choose one thing your process is missing today. It's a useful topic for your first conversation with the team.
QUESTIONS AND ANSWERS
Frequently asked questions.
Should a B2B portal replace sales representatives?
It does not have to. It can take over repetitive service and give sales representatives more time for consulting and complex relationships. The scope should result from what customers need.
When to add AI to the platform?
When the basic purchase works reliably and there is a specific task requiring interpretation, e.g., finding a product based on a description of the need. First ensure that the catalog and selection rules are good enough.
