While Square is certainly an attractive option for businesses just starting out, we've found that over the long haul, Square isn't an ideal fit for many folks. To better serve our merchants, we've created our own processing solution in partnership with Gravity Payments, which you can read more about here.
The big difference between using Square and a fully integrated solution is that Square (and any other third-party POS) requires recording sales in two places, which can be a time-consuming and error-prone process. In contrast, letting ConsignCloud handle payment processing for you means better technical support, a smoother setup process, and fewer moving parts to distract you when processing sales — the most crucial part of your business.
That said, if you prefer to stick with Square Register, you can use it as a standalone device. You will need to ring up the items in ConsignCloud to get a total, switch to Square Register (a 4-finger swipe on an iPad is a quick way to do this), process the transaction through Square, and then return to ConsignCloud to finalize the transaction.
