Zap Bill

Zap Bill is online invoicing software for freelancers, contractors, consultants, agencies and small businesses that need to send professional invoices and get paid without the cost and complexity of a full accounting package. Built and run independently in the UK and available worldwide, Zap Bill focuses on one job: getting you from “I need to bill a client” to a polished PDF invoice in about a minute. Start free, no signup required Open the free invoice generator in any browser, fill in an invoice or quote, and download it as a PDF without creating an account. A free account adds three saved invoices a month, a customer database, a product and service catalog, expense tracking, payment recording and shareable client links, plus a 14-day trial of every Unlimited feature with no credit card needed. Tax-ready invoices for any country Country presets fill in your currency, date format, default tax rates and tax number label, so VAT invoices, GST tax invoices and sales tax invoices start with the right fields. Invoices support per-line tax rates, multiple taxes, discounts, shipping, deposit and retention deductions, tax point dates, company registration numbers, and multi-currency and multi-language output. Add your logo, signature and your own payment link, and email invoices from your own address, so every invoice looks like it came from your business. Quotes and estimates that convert Create quotes and estimates, send them to clients, and turn accepted quotes into invoices without re-typing a thing. Unlimited plan for businesses that bill every week Unlimited removes the saved-invoice limit and automates the admin that slows down cash flow: recurring invoices on weekly, monthly or quarterly schedules, automatic payment reminders, late fee automation, time tracking billed straight onto invoices, customer statements and custom invoice templates. Invite teammates to a shared workspace, connect your own systems through the REST API, and use CSV import and export to move invoice history, customers and products in or out. No transaction fees, no lock-in Zap Bill never takes a cut of your payments. Get paid by bank transfer, PayPal, your own payment link or whichever method suits you. There are no contracts, you can cancel anytime, and Unlimited comes with a 30-day money-back guarantee. What Zap Bill is, and isn’t Zap Bill is a dedicated invoice generator and billing tool, not double-entry accounting software. It doesn’t do bank feeds, reconciliation or payroll, which is exactly why it’s quick to learn, fast to use and a fraction of the price of platforms like Xero, QuickBooks or FreshBooks. If you need professional invoices, quotes and receipts without the accounting overhead, Zap Bill keeps billing simple so you can get back to the work you get paid for.
