A product with 40 units left only in XXS and XXL looks 'in stock' to ad platforms, but converts at a fraction of normal rate. SizeRun Guard catches broken curves immediately.
Ad spend keeps pushing shoppers to hero products where core sizes are already sold out, hurting conversion and ROAS. SizeRun Guard replaces fragile manual checks with a repeatable, human-approved workflow built around your catalog and finance rules.
01
Stop Wasting Ad Budget on Fringe-Size Leftovers
A product with 40 units left only in XXS and XXL looks 'in stock' to ad platforms, but converts at a fraction of normal rate. SizeRun Guard catches broken curves immediately.
02
Category-Specific Core Size Definitions
Define what 'healthy stock' means per category — e.g., Women’s Footwear requires 37–40 in stock, while Men’s Tops require at least 3 of S/M/L/XL above 5 units.
03
Instant Restock Re-Activation
As soon as warehouse replenishment restores core sizes, products automatically flip back to 'Eligible' so campaigns capture peak demand without manual spreadsheet checks.

ILLUSTRATIVE SCENARIOS
Example edge cases for SizeRun Guard
SCENARIO 01
Hero Runner With 80 Units Only in Extreme Sizes
The operational problem
A top-spending sneaker still had 80 total units in stock, but 100% of sizes 38–41 were sold out, cutting conversion rate by 68%.
Example outcome with SizeRun Guard
Flagged immediately as 'Core sizes 39 and 40 unavailable' and shifted ad budget to the Sand colourway with a complete size run.
SCENARIO 02
Mid-Week Warehouse Restock
The operational problem
150 units of a bestselling jacket arrived at the 3PL on Wednesday, restoring sizes S, M and L.
Example outcome with SizeRun Guard
Automatically flipped the style from `Flag` to `Eligible` in the next sync so paid social resumed promoting it the same day.
SCENARIO 03
Collection Top-Row Merchandising
The operational problem
Top-sorted collection items had fragmented sizes, frustrating organic shoppers on mobile.
Example outcome with SizeRun Guard
Provided a daily broken-size report so merchandisers demoted fragmented styles below full-size-run alternatives.
