What the Bulk Variations Manager plugin does
WooCommerce's built-in generator adds variations in batches of up to
50, and each variation's price is then entered by hand.
Bulk Variations Manager replaces that with one form. Select a base
product, set its base price, choose the attributes, and enter a price
difference for each attribute value. The plugin generates every
combination and calculates each final price.
Example: A T-shirt with 6 sizes, 6 colors and 3 fits
has 108 variations (6 × 6 × 3). With a $12 base price, Small adds
$0, Medium adds $1, Large adds $3 and White subtracts $0.50. The
plugin applies those differences to all 108 variations in one run.
