QuickBooks POS reviews V10

I'm looking for guidance and assistance, I'm willing to pay for your time and effort.

I run a mobile accessories business and my stocks comes and goes very fast, in addition I have several sales avenue such as website, facebook and my small retail shop.

I've decided to go with woo commerce with qbpos ver 8, 9, 10 or qbpos ver 11 2016. I found 2 plugins both from 61extensions that integrates woo with qbpos. (Links: and ) which looks great but at the same time I found some really bad reviews about it at

I'm in a dilemma here as I have yet purchased qbpos. I needed to make sure the plugin works first before purchasing, otherwise if the plugin doesn't work then it'll be a huge waste of money because it's important that the inventory and website stocks is both up to date otherwise I may be in trouble for selling products that is out of stock to my customers, which was the whole point of me revamping the website.

Here are my questions:

1) Have anyone here used either plugins from 61extensions before and/or experienced with integrating woo + qbpos? I hope to hire you to help us out.

2) Aside from the plugins mention above, is there other methods to integrate woo with qbpos?

3) Is there a free or trial version of quickbooks pos so at least I can purchase the plugin, if it doesn't work at least I'll just lose the money on purchasing the plugin.
