How to sync inventory for product variants?

[AnaGRN]

Hello,

Does anyone know an app that could syncronize inventory for product variants? 

My products are always composed by 2 variants

1st variant: sizes with stock

2nd letter: letters with stock

How can i track the inventory of all of the variants?

Thank you in advance.

Ana
