The verdict in three sentences
For a distributor with 45,000 industrial part numbers in Amsterdam, BigCommerce B2B Edition (from around USD 1,000 a month in licence plus EUR 20,000 to 50,000 in implementation) is attractive as long as pricing, catalogue and part-number search fit its native features. Beyond that, a custom platform (EUR 60,000 to 140,000, 4 to 8 months) costs more upfront but becomes competitive on 3-year total cost once apps, workarounds and licence tiers that rise with revenue add up. The decision rests on three measurable criteria: search response time, the number of apps and workarounds needed, and the share of revenue made online.
Where a SaaS platform hits its limits at 45,000 SKUs
BigCommerce handles a 45,000-product catalogue comfortably. Limits appear elsewhere: customer-specific net prices synced from the ERP for hundreds of accounts, cross-reference search (finding a SKF bearing by its FAG or NSK equivalent), quote workflows with sales approval, and quick order by file upload or 50-line entry. Each gap is filled by an app or a custom integration, and licence tiers rise with online revenue.
| Symptom (2026 order of magnitude) | Acceptable B2B threshold | Common degraded situation |
|---|---|---|
| Search response time | < 300 ms | 1.5 to 3 s |
| Category page load | < 1.5 s | 3 to 5 s |
| Apps installed | 10 to 20 | 30 to 45 |
| Custom scripts and middleware jobs | 0 to 5 | 15 to 25 |
| Zero-result search rate | < 5% | 15 to 25% |
| Pricing records synced from ERP | Up to a few hundred price lists | Thousands, with sync delays |
Before choosing, a EUR 3,000 to 6,000 audit shows whether the SaaS route covers your must-haves or whether you will spend three years working around it.
Comparing both options over 3 years
| Item (EUR excl. VAT, 2026 order of magnitude) | BigCommerce B2B Edition | Custom platform |
|---|---|---|
| Initial implementation | 20,000 to 50,000 | 60,000 to 140,000 |
| Annual licence (from USD 1,000 per month, rising with revenue) | 11,000 to 40,000 | 0 |
| Apps and search engine per year | 4,000 to 12,000 | 1,200 to 6,000 |
| Hosting per year | Included | 3,600 to 9,000 |
| Maintenance and middleware per year | 8,000 to 18,000 | 8,000 to 18,000 |
| 3-year total cost | 89,000 to 260,000 | 98,000 to 239,000 |
| Time to launch | 3 to 5 months | 4 to 8 months |
The licence line is the swing factor. BigCommerce Enterprise pricing is negotiated and scales with gross merchandise volume, so a distributor doing EUR 4 to 6 million online typically lands well above the entry price. A custom build carries no licence but requires a reliable partner for hosting and maintenance.
The features that tip the decision
Search comes first. A maintenance buyer searches by part number, often mistyped, and expects an instant result with the in-stock equivalent. Quotes come second: in industrial parts, 30 to 50% of revenue still goes through quotes, and a portal that cannot handle that flow leaves half the business on the phone. ERP sync is third: stock per warehouse, supplier lead times, net prices and customer credit in real time, plus Dutch specifics such as iDEAL and invoice payment on account.
If those three needs are covered natively or by fewer than 5 reliable apps, stay on BigCommerce. If you need 10 apps and custom middleware, a custom or headless platform connected to your ERP becomes the rational choice.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Daan, ecommerce director of an industrial parts distributor in Amsterdam (illustrative example), makes EUR 4.2 million online out of EUR 18 million revenue. His BigCommerce setup costs EUR 48,000 a year in licence, apps and middleware. A EUR 120,000 custom build cuts that to EUR 16,000 a year. If faster search and online quotes raise the online share from 23% to 28%, that is EUR 900,000 of extra revenue at 25% gross margin, or EUR 225,000 a year. On this scenario the rebuild pays back in under 6 months.
FAQ
Is BigCommerce B2B Edition enough for industrial distribution?
Yes for a catalogue up to 50,000 SKUs with a few dozen price lists, especially with an external search engine. Beyond 200 to 300 customer-specific net price lists synced from the ERP, sync and performance become harder to manage.
What does a pre-decision audit cost?
Expect EUR 3,000 to 6,000 and 2 to 3 weeks. It measures response times, lists required apps and prices both scenarios over 3 years.
Can we migrate without losing SEO?
Yes, with a complete 301 redirect plan across 45,000 product pages and categories. A temporary 5 to 15% dip in organic traffic for 4 to 8 weeks is common.
What about other SaaS options?
Shopify Plus B2B and similar platforms start around USD 2,300 a month. They suit standard pricing rules, less so when cross-reference search is critical.
How long does a custom platform take?
About 4 months for a core scope (catalogue, search, pricing, ordering), up to 8 months with quotes, file uploads and a full customer portal.
