The verdict in three sentences
Shopify Plus B2B is an excellent choice when your commercial rules stay standard: company-specific catalogs, payment terms, volume discounts, and you accept a subscription of at least 2,300 USD a month. A custom platform becomes more cost-effective once your 1,500 resellers need complex pricing rules, seasonal pre-orders or tight ERP sync. Over 3 years, the total cost gap can exceed 100,000 USD either way: calculate it on your own rules, not on a brochure.
The context: 1,500 resellers and rules that do not fit a box
The e-commerce director of a textile manufacturer (home linen and workwear) currently sells to 1,500 resellers through field reps and a PDF catalog. Orders cover 2,800 SKUs with sizes and colours, seasonal pre-orders 6 months ahead, in-season replenishment and prices that vary by reseller status (wholesaler, retailer, buying group), annual volume and sometimes region.
| Business need | Native Shopify Plus B2B | With third-party apps | Custom |
|---|---|---|---|
| Company-specific catalogs and prices | Yes | Yes | Yes |
| Annual volume tier discounts | Partial | Yes, 100 to 300 USD per month | Yes |
| Seasonal pre-orders with deferred delivery | Not native | Yes, with limits | Yes |
| Size x colour matrix quick entry | Partial | Yes, 50 to 200 USD per month | Yes |
| Net 30 or net 60 payment terms | Yes | Yes | Yes |
| ERP sync (stock, credit, invoices) | Via connector | Connector 300 to 1,000 USD per month | Built to spec |
| Multi-level approval at reseller | Partial | Depends on app | Yes |
Shopify Plus is moving fast on B2B and many manufacturers are well served by it. The risk appears when 4 or 5 apps pile up to fill gaps: stacked monthly fees, conflicting updates and business logic scattered across vendors.
Total cost over 3 years: the real comparison
| Item (2026 estimate) | Shopify Plus B2B | Kolonell custom platform |
|---|---|---|
| Platform subscription | 2,300 USD x 36 = 82,800 USD | No licence |
| B2B apps | 200 to 1,000 USD per month, 7,200 to 36,000 USD | Features built into development |
| Setup by a partner agency | 30,000 to 90,000 USD | Complex app: 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) |
| ERP connector | 10,000 to 25,000 USD + possible subscription | Included in quoted scope |
| Maintenance and enhancements | 1,000 to 3,000 USD per month at agency | 120,000 FCFA per month (183 EUR), enhancements quoted |
| Hosting | Included | Quoted separately |
| Code ownership | Theme and apps with third parties | Code and data with you |
Shopify Plus has real strengths: managed hosting and security, a rich ecosystem, launch in 3 to 4 months. Custom requires tighter scoping, 4 to 6 months of development and a team able to evolve the platform. Full Kolonell grid: simple app 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR), medium 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), complex 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR). A portal for 1,500 resellers with pre-orders and ERP sync sits in the complex band.
How to decide in 4 questions
First, how many of your pricing rules does Shopify Plus B2B cover natively? Above 80%, the platform is probably the right call. Second, does your ERP have a maintained Shopify connector? Third, do you also plan a consumer (B2C) channel? Shopify Plus then serves both. Fourth, how much time will your team put into the tool? A custom platform needs an internal owner who can prioritise enhancements.
Mini case study
Mark, e-commerce director of the manufacturer, models both scenarios over 3 years in USD. Shopify Plus: 82,800 USD subscription + 600 USD a month in apps (21,600 USD) + 55,000 USD setup + 16,000 USD ERP connector + 1,600 USD a month agency maintenance (57,600 USD) = about 233,000 USD. Custom: a 14,000,000 FCFA development project (about 21,340 EUR) + 6,588 EUR of maintenance + a prudent 25,000 EUR reserve for enhancements and hosting = about 53,000 EUR, roughly 57,500 USD. If 30% of the 1,500 resellers go online and each digital order saves 16 USD of handling across 8 orders a year, the annual gain is 450 x 8 x 16 = 57,600 USD. Both options pay off, but the total cost gap points Mark towards custom, provided scoping is done carefully.

FAQ
Does Shopify Plus really handle B2B in 2026?
Yes, with company catalogs, payment terms and specific prices. Limits show on seasonal pre-orders and complex discount rules, often filled by 2 to 5 paid apps.
Can we start on Shopify and migrate later?
Yes, but migrating 1,500 reseller accounts with their history and prices often costs 15,000 to 45,000 USD. It is better to decide after auditing your commercial rules.
How long does a custom platform take to launch?
Allow 4 to 6 months for a complex scope, then a pilot with 50 to 100 resellers before full launch.
How does ERP sync work?
Stock, customer credit and invoices sync every 5 to 15 minutes via API. Approved orders flow into the ERP with no re-keying.
Should we keep field sales reps?
Yes, the portal frees them from data entry. They focus on acquisition and key accounts, and can place orders for a reseller from their tablet.
