I use ERP.Aero Aviation ERP Platform to run our aviation supply business entirely from RFQ to invoice, and I find the marketplace API integration for RFQs and inventory management awesome. Transitioning from notes, spreadsheets, and memory to this platform has been better than awesome. I really like how it's easy to use, we were up and running fast, and the support is better than advertised. Their team responds fast and is always available, which makes a huge difference. Moreover, the initial setup was easy, and they helped by importing our data and training our staff, allowing us to go live in just a few weeks. The platform is comprehensive, providing audit trails, storage for documents, and basically everything we need on-site.
