At a glance
Catalogue product count grouped by brand (BC’s vendor / brand field). Tells you how the catalogue is split across suppliers, which brands carry the catalogue depth, and where supplier concentration risk lives. The brand split is a leading indicator for supplier-relationship management.
Calculation
Worked example
A US homewares brand on BigCommerce Pro that resells multi-brand inventory plus a private label, snapshot at 12 Apr 26.
What’s interesting:
- House Label at 33.2% is healthy private-label concentration. Mature multi-brand retailers typically run 25-40% on house brand; the margin uplift on private label (60-80%) vs branded (25-40%) is the financial case. Below 25% suggests under-developed private label; above 40% suggests over-reliance.
- Brand A at 14.9% is the supplier-concentration risk. A 15% catalogue share + multi-year contract means a price increase, a stockout, or a contract dispute on Brand A hits 15% of the catalogue. Most stores diversify when single-brand share approaches 20%.
- The 26.2% long-tail across 40 brands is structurally interesting. Each long-tail brand carries 30-100 SKUs on average; together they make up a quarter of catalogue. Long-tail brands collectively are the 2nd-largest “brand” but are operationally fragmented. Consolidation potential: drop the bottom 10-15 brands with lowest sell-through, simplifies merchandising significantly.
- 45 Unassigned products is small but consequential. These products lack a brand value; Amazon Channel Manager and Google Shopping require a brand attribute and will reject these from feeds. Fix the brand field for these 45 products before they affect marketplace listing eligibility. Often the cause is a CSV import where the supplier didn’t provide brand data; a quick mapping fix.
- Brand-level revenue often differs from brand-level catalogue share. A brand with 5% of products may generate 25% of revenue (high-velocity) or 1% (long-tail catalogue padding). Pair with Top Products and BC Top SKUs Revenue for the revenue-weighted brand view.
- Audit the Unassigned bucket urgently. Empty brand fields break marketplace feeds; fix in a one-time bulk update.
- Review supplier-concentration risk. Brands above 15% catalogue share + above 25% revenue share need succession planning, what’s the diversification strategy if that supplier fails?
- Prune long-tail brands annually. The 40th-ranked brand probably represents 0.5-1.5% of catalogue and 0.2-0.8% of revenue. Operations cost (separate supplier relationship, separate purchase orders, separate returns process) often outweighs the revenue contribution.
- Watch private-label growth deliberately. House Label growth from 30% to 50% over 2-3 years is a pricing-and-margin transformation; it should be deliberate, not accidental.
- Cross-reference brand list with marketplace brand registry. Amazon’s Brand Registry requires verified brand ownership; non-registered brands lose access to A+ Content and Brand Analytics, materially hurting Amazon channel performance.

Reconciling against the vendor’s own dashboard
Where to look in BigCommerce Control Panel: Catalogue → Brands shows the master brand list with product counts. Catalogue → Products supports filter by Brand. For marketplace-feed validation, Channel Manager shows which brands are eligible for which channels. Amazon Brand Registry verification status lives in Amazon Seller Central, not in BC.
