We use A2X for both Shopify and Amazon. Though the initial setup was not intuitive on the billing side, their customer support was solid and we ended up creating the two accounts we needed to get everything synced up. Works wonders.

It does exactly what I need it to do. Great support i n the set up.

I love this system, because it is one of the most used worldwide, because it transmits a solidity in the accomplishment of its work, which generates confidence, for the experts in accounting in company leaders, who use this software to carry out their operations related to electronic commerce, mentioning that I like at great scales, its data quality control to lead to promote exclusive and necessary information, for the effectiveness of these commercial and economic facts.
