You probably have a version of this leak.
If any of these signals match your subscription or wellness operation, the same pattern is likely already costing you margin.
Monthly P&L cadence
You only see gross margin trends during month-end close, by then any input-cost drift is already 30–60 days deep.
Hero subscription SKUs
A handful of SKUs drive most subscription revenue; even small COGS drift on them compounds fast.
Many manufacturers
You source from a dozen-plus manufacturers and supplier price changes don’t always flow into purchasing on the same week.
No COGS-by-SKU view
Your accounting system shows gross margin at the company level, not the SKU level, so concentration leaks hide in the average.
Questions operators ask about quiet COGS drift.
Why doesn’t our P&L catch this faster?
The P&L is a monthly aggregate, drift on a 6-SKU subset is masked by stable margin across the other 74 SKUs in the catalog. The signal lives in per-SKU gross margin trended against a rolling 12-week baseline.
How does Halia know which baseline COGS to compare against?
Halia builds a rolling 12-week baseline for COGS per SKU using your invoice + order data. When a current-week landed cost breaches the upper band, it alerts immediately, before the topline gross margin moves enough for accounting to flag it.
Is 12-point margin compression on a hero SKU really $115K?
If 6 hero SKUs do ~$80K/month combined (a typical ~30% revenue share on an $8M brand), then 12 points of margin compression on those SKUs costs ~$9,600/month, $115K annualised. The dollar impact scales linearly with hero-SKU revenue share.
