Crescere.VF is online invoicing software for freelancers, small businesses and accounting firms in Spain. It complies with Verifactu, the Spanish Tax Agency's system that requires every invoice to carry a chained hash and a QR code. Create invoices, quotes and delivery notes, send them by email and get paid by card or PayPal through a client portal. For subscription businesses, it charges customers' cards automatically through the merchant's own Redsys terminal, issues a Verifactu invoice for every successful payment and retries failed ones, with no per-transaction fee. Free plan with Verifactu and up to 10 invoices a month.
