Hi HackerNews, first time solopreneur here (if that is a word) and my very first launch of a product which I built alone, start to finish. Not sure what to expect. I am super pumped and excited to show Vatfy to the HackerNews community and am very nervous (and scared to death at the same time) of what you guys think of my niche product. I created Vatfy because I did not find a simple and cheap alternative to making my invoices tax compliant. Yes, there are other solutions out there that do VAT validations, but most just do this initially (one time) or are insanely expensive (at least for my gusto). This kind of sucks if you are invoicing on a monthly basis as a SaaS (for example). So I created Vatfy to validate EU VAT ID numbers, calculate prices for B2B and B2C customers based on their location and help me figure out if you want to invoice net or gross pricing (with and without VAT percentages), be able to look up up-to-date VAT rates as well as have a place to store all my validation evidence in case the local tax authority ever wants to do an audit. Also very unsure about pricing at the moment. 100 free validations per month is a lot, but I always had the small business user in mind, who cannot or does not want to purchase a more expensive solution. Any feedback to Vatfy more than welcome!
