The verdict in three sentences
A distributor that still receives 60% of its orders by phone and fax is paying its inside sales reps to re-key order lines instead of selling. A B2B ordering portal with customer-specific pricing, visible account balance, one-click reorder and an ERP connection typically moves 30 to 50% of orders online within 12 months. The choice is between a B2B SaaS at 300 to 1,500 EUR (about 325 to 1,600 USD) per month for a standard catalog and a custom portal at 20,000 to 60,000 EUR (about 22,000 to 65,000 USD) as soon as your pricing terms and ERP are specific.
Why phone and fax cost more than they seem
For a food wholesaler near the Port of Miami, an electrical supply distributor in Doral or an office supplier in Hialeah, phone orders have a hidden cost: 4 to 8 minutes of data entry per order, 2 to 4% of incorrect lines (wrong SKU, wrong quantity), and customers who can only order during business hours. Restaurant owners, electricians or facility managers who order in the evening or on weekends switch to competitors that already offer a portal.
| Indicator (distributor with 15 to 40 M EUR revenue) | Phone and fax orders | B2B portal orders |
|---|---|---|
| Processing time per order | 4 to 8 minutes | under 1 minute (review) |
| Incorrect line rate | 2 to 4% | 0.3 to 0.8% |
| Ordering window | 7 am to 6 pm on weekdays | 24/7 |
| Average order value | baseline | +8 to 15% (suggestions, reorder) |
| Entry cost per order | 3 to 6 EUR | 0.5 to 1 EUR |
| Customer visibility on balance and invoices | by calling customer service | self-service |
These figures are 2026 orders of magnitude seen at regional distributors; the real gain depends on lines per order and the quality of your item master data.
B2B SaaS or custom portal: 2026 pricing and limits
B2B SaaS platforms (wholesale-focused tools, B2B modules for Shopify or BigCommerce) deploy quickly and cover the catalog, customer accounts and group pricing. Their limits show up with cascading customer discounts, net prices negotiated on 3,000 SKUs, different free shipping thresholds by zone, or distribution ERPs (NetSuite, Sage X3, Epicor, food distribution systems) that require fine-grained synchronization.
| Criterion | B2B SaaS | Custom portal |
|---|---|---|
| Setup cost | 2,000 to 10,000 EUR | 20,000 to 60,000 EUR |
| Recurring cost | 300 to 1,500 EUR per month | 200 to 600 EUR per month (hosting, maintenance) |
| 3-year cost (mid-range) | 38,000 to 45,000 EUR | 47,000 to 55,000 EUR |
| Time to launch | 1 to 3 months | 3 to 5 months |
| Customer pricing and cascading discounts | price groups, sometimes limited | free rules, pulled from the ERP |
| Balance, invoices, credit notes online | often partial | complete, real time |
| ERP connection | standard connector or CSV import | custom two-way API |
Over 3 years the cost gap is small. Custom is justified when the portal must reflect your commercial terms exactly: a customer who sees a price different from the one on their invoice abandons the portal within weeks.
The features that drive adoption
A B2B portal is not judged by its storefront but by its ordering speed. Business customers always order the same items: reorder features (repeat last order, usual shopping lists, quick entry by SKU) matter more than design. Adoption also follows a simple rule: sales reps must push the portal, not suffer from it.
| Feature | Impact on adoption | Priority |
|---|---|---|
| Net customer prices displayed | essential for trust | launch |
| One-click reorder and usual lists | 40 to 60% of online orders go through it | launch |
| Quick entry by SKU or file upload | essential above 20 lines | launch |
| Balance, invoices and credit notes viewable | 30% fewer customer service calls | launch |
| Stock and delivery time per item | fewer cancelled orders | phase 2 |
| Mobile app or PWA for drivers and customers | ordering in the field, kitchen or job site | phase 2 |
| Sales rep commission kept on online orders | avoids internal resistance | launch |

Carlos, sales director of an electrical supply wholesaler in Doral, handles 26,000 orders per year for 22 million EUR (about 24 million USD) of revenue, 60% of them by phone and fax. He invests 42,000 EUR in a custom portal connected to his ERP, plus 4,800 EUR per year of maintenance. After 12 months, 40% of orders go online, or 10,400 orders. At 5 minutes saved per order, the inside sales team recovers 867 hours, about 26,000 EUR of time reallocated to prospecting. The 10% increase in average order value on those orders, at a 25% gross margin, adds about 88,000 EUR of margin. The portal pays back in under 5 months.
FAQ
How many customers really order online in the first year?
As a 2026 order of magnitude, 30 to 50% of orders move online after 12 months if the sales team supports customers. The 20% most regular customers adopt first, often from month 3.
Do we really need to connect the portal to the ERP?
Yes, without a connection you re-key online orders, which cancels the gain. The connector represents 25 to 35% of a custom portal budget, or 6,000 to 18,000 EUR.
Can we offer online payment to business customers?
Yes for new customers or small accounts, by card or bank transfer. Customers on account keep their net 30 or net 45 terms, invoiced as usual.
How do we keep sales reps from slowing the portal down?
Keep their commission on their customers' online orders and give them a portal dashboard. This simple rule often lifts adoption from 15% to over 35% within a year.
How long does it take to launch a custom portal?
Count 3 to 5 months, including 4 to 6 weeks for the ERP connection and customer pricing migration. A one-month pilot with 20 to 30 customers is strongly recommended.
