NeatInvoice

NeatInvoice is an invoicing workspace built for freelancers and independent consultants who send invoices regularly and want to get paid without the back-and-forth. Most invoicing tools tell you when a payment is overdue. NeatInvoice tells you when your client opened the invoice — before it's even late. Every invoice gets a live client link: a URL your client opens in their browser, no PDF attachment needed. You see exactly when they viewed it, with timestamp and device. No more sending a follow-up email just to ask "did you get it?" When a payment is late, NeatInvoice handles the follow-up for you. Set a reminder offset once, and automated emails go out to your client after the due date — so you stay focused on work, not chasing payments. Everything lives in one workspace across two screens: the invoice editor where you create and manage invoices, and the finance overview where you see your full billing picture — paid this month, still owed, overdue, revenue trends, top clients, and which services earn the most. Key features include live invoice links with view tracking, email dispatch directly from the app, automated payment reminders, recurring invoice schedules for retainer clients, multi-currency support across 40 plus currencies, invoice labels in 12 languages, multiple business workspaces for freelancers managing more than one brand, saved client and item library for faster invoice creation, and PDF export always available. Free plan includes 25 invoices per month, live link tracking, finance overview, and PDF export with no credit card required and no expiry. Pro plan adds email dispatch, automated reminders, and recurring billing.
