The ease of use, ability to customize features with our own branding is what I like best about this product! It makes it easy as pie when you are trying new things out or using older versions that didn't have all your customizations in place yet - just import an existing document into one which does already include those changes/customization(s) needed by us now.
Nothing specific at present but will update once we find something good enough (or not). We've been able solve issues related to accounting processes within sales teams both internal & external customers alike while also allowing some automation where possible without much manual effort involved from Accounting team's end thus saving time spent during their workflows.
