Can I add multiple QuickBooks company in one company of onlinecheckwriter?
Yes, you can. You can add multiple companies of QuickBooks into one company of onlinecheckwriter, unless you want to separate it completely.
For instance, some business people like to keep each Corporation completely different. In this case, they don’t want to create a multiple email ID and having to switch around to each account. So adding a company means you can access both of them using the same email ID.
Sometimes some business prefers to keep each division of the industry with its own online check writer account. So adding company, they can access all of them using the same email ID.
