Your Inventory Management Resource • Online 24/7

From very basic to advanced.

Inventory management how-to training and

"Just do it!" calculators.


For retailers, inventory is...

...the only thing that makes money for you;

...the thing that takes up most of your time;

...the part of your business that soaks up the most cash.

And something that never seems to be right!

How best to deal with inventory? 

The pros in retailing use "Open-to-Buy" (by some name or another). 

Why? Because an Open-to-Buy...

...can improve margins and profits.

...can reduce the time spent on inventory management.

...can greatly improve cash flow.

...can reduce markdowns by reducing excess inventory.

And, it can help have the right merchandise in your store at the right time...and avoid having excess stock!
