How to Choose a B2B Online Ordering Platform

November 14, 2026 · 4 min read

This guide walks you through selecting a B2B online ordering platform that fits your wholesale business, from evaluating your current process to testing with real buyers.

What you need

• Your current wholesale price list with any volume discounts or customer tiers
• A list of your existing wholesale customers and their typical order patterns
• Access to your inventory management system or current stock tracking method
• Your payment terms (net 30, net 60, credit requirements)
• Names of any software you use for accounting, inventory, or fulfillment

Step 1: Map your current wholesale process

Write down every step a buyer takes to place an order today. Include how they request a price list, how they submit orders, how you confirm inventory, how payment happens, and how you send shipping updates. Note where orders get delayed, where mistakes happen, and where you spend the most time manually entering data. This becomes your requirements list.

Step 2: Identify must-have features for your pricing structure

Your platform must handle your actual pricing model. If you offer tiered pricing based on order volume, customer type, or product category, confirm the platform supports multiple price lists per customer. If you extend net terms, verify it can display payment due dates and integrate with credit vetting services like Balance, Resolve, or TreviPay. If you have minimum order quantities or case pack requirements, make sure those rules can be enforced at checkout.

Step 3: Check integration compatibility

List every system that touches your wholesale orders: your accounting software, inventory management, warehouse management, shipping platform, and CRM. Contact platform vendors and ask for documentation showing how their system connects to yours. Real-time inventory sync matters most if you sell across multiple channels. ERP integration with systems like NetSuite, SAP, QuickBooks Enterprise, or Microsoft Dynamics 365 prevents double entry but often requires custom development work.

For brands that need help with integration planning and setup, Get Wholesale Orders builds B2B portals with ERP and WMS connections included, handling the technical work so the system launches ready to take orders.

Step 4: Evaluate the buyer experience

Request a demo account and place a test order as if you were one of your customers. Check whether product search works well, whether images and descriptions load quickly, and whether the cart clearly shows pricing, minimums, and payment terms. Ask if buyers can reorder from past orders, save favorites, or download invoices. A confusing buyer experience means fewer orders, even if the backend works perfectly.

Step 5: Compare total cost over 12 months

Add up platform fees, transaction fees, payment processing fees, integration costs, and any charges for user seats or API calls. Many platforms charge a monthly subscription plus a percentage of each order. Others charge by active buyer count. Include the cost of your time: if a platform requires 10 hours a month of manual work that another automates, that time has a dollar value. Pick the option that costs less when you include labor.

Step 6: Test with a small group of real customers

Before rolling out to your full buyer list, invite 5 to 10 customers to use the new platform alongside your old process. Give them a small incentive to try it and ask for feedback after their first order. Watch for complaints about confusing navigation, missing product information, or payment problems. Fix those issues before the full launch.

Step 7: Plan your migration and launch timeline

Set a date to move all buyers to the new system. Decide whether you will import past order history or start fresh. Prepare an email explaining the change, including login instructions and a contact method for questions. Plan to monitor the first two weeks closely, responding quickly to any technical problems or buyer confusion. Most B2B portals take 3 to 6 weeks to build and launch when integration and data migration are included.

Troubleshooting

Problem: The platform cannot handle your pricing structure. If your pricing model is too complex for the platform's standard features, ask whether custom pricing rules can be added through an integration or API. If not, you will need to either simplify your pricing or choose a more flexible platform. Forcing a mismatch leads to manual workarounds that defeat the purpose of automation.

Problem: Integration costs exceed the platform subscription cost. Custom integration work can run thousands of dollars and take months. If the integration quote is higher than a year of platform fees, compare the cost against hiring a service that includes integration, or consider a platform that offers pre-built connectors for your systems. Alternatively, accept some manual data export and import if order volume is low enough to make that practical.

Problem: Buyers are not adopting the new platform. If customers continue placing orders by email or phone after launch, the platform is either too complicated or does not offer enough advantage over the old method. Call your top 10 customers, ask why they are not using it, and fix the specific barriers they name. If the platform saves you time but not them, consider adding an incentive like a small discount for portal orders, or accept that some customers will always prefer personal contact.
