What Customers Say
“I built QuickBilling because sending an invoice should feel like sending a link. I want to know when it has been opened, and I want reminders to go out before and after the due date without me writing them by hand.”
“I send an estimate as a link, my client accepts it without needing an account, and I convert it to an invoice in one click.”
“I can see when a client has opened an invoice, and the reminder schedule does the nudging for me. I no longer write those awkward follow-up emails.”
Solution Plus moved its client billing to QuickBilling
Solution Plus Tech Consultancy is a small consultancy in Sharjah. It sends each estimate to a client as a link, and the client accepts it online without an account.
An accepted estimate becomes an invoice in one click. Clients can mark invoices paid, and the team keeps its expenses in the same workspace.
“Our estimates, invoices and expenses now live in one place.”

Free Invoicing Software FAQs
Is QuickBilling Free?
Yes. The Free plan costs nothing and needs no card. It includes 1 workspace, up to 5 customers and unlimited invoices and estimates, with recurring invoices and expense tracking.
Is There A Limit On How Many Invoices I Can Send?
No monthly limit on any plan. Email sending has a daily limit to protect deliverability; sharing by link has no monthly limit.
Do My Clients Need An Account?
No. Clients open your invoice or estimate from a link, download the PDF, accept or decline an estimate, or tell you they’ve paid, without signing up.
Can QuickBilling Remind My Clients To Pay?
Yes. When you first email an invoice, reminders the day before and two days after the due date are checked for you to keep or uncheck, plus optional 7- and 14-day follow-ups. They stop once the invoice is paid.
How Does Invoice Link Tracking Work?
Every invoice or estimate shared as a link records each visit. Free shows whether, when and how often it was viewed; Premium and Unlimited add IP address, approximate location, device and browser.
Does QuickBilling Track Expenses?
Yes, on every plan. Log expenses with receipts, set budgets and see income and expenses together in profit and loss and tax reports.
Can I Cancel At Any Time?
Yes. Cancelling stops future charges, you keep paid features until the end of the period, and your account then moves to Free with your data intact.
How Is QuickBilling Different From Wave Or Zoho Invoice?
It focuses on getting invoices opened and paid rather than full accounting: open tracking, no client login, expenses in the same workspace, and an API and MCP server to automate routine work.
Can I Try The Invoice Preview Without An Account?
Yes, the preview on this page works in your browser. To save, send and track an invoice, create a free account; there’s no separate no-sign-up generator.
