I have run thousands of fast successful transactions over the last few years since this app first came out. It’s extremely reliable, which is SO important. Except for only a couple of glitchy moments in the years I’ve used this app, it has worked perfectly. When those glitches occurred, tech support was concerned, quick to react, and fixed things immediately with personal care and follow-up. I also like the webpage. It so easy to quickly set up or edit wording for email receipts. This is a real review. My business is the Nancy Shepherd House B&B in Winchester VA. Google it.
