Why this matters

Tracking contribution margin per SKU, inclusive of marketplace fees, prevents "profitable on paper" products from draining cash.

What to do about it

• Sales tax nexus rules vary by state or country and are one of the most commonly overlooked compliance risks for growing sellers.
• Separating inventory as an asset from cost-of-goods-sold timing is a common source of misleading monthly P&Ls.

The takeaway

None of this requires a large team or budget to start — it requires a consistent process. Review the metric or workflow behind "Sales Tax Nexus Basics for Growing Sellers" on a fixed schedule, and treat the first pass as a baseline to improve on, not a finished system.
