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.”

Invoice Automation Software FAQs
Short answers to what people ask before they start.
What Is Invoice Software?
Invoice software creates invoices and quotes (estimates), sends them to clients and tracks what happens next. QuickBilling sends each one as a share link, an email and a PDF, then shows you when it’s opened.
Can Clients Accept A Quote Online?
Yes. Clients open the quote from the link and accept or decline it without an account. You get an email when they respond.
How Do I Turn A Quote Into An Invoice?
Open the accepted quote and convert it in one step. Every line item carries over, so nothing is retyped.
Will I Know When My Invoice Is Opened?
Yes. Every plan shows whether, when and how often a link was viewed. Premium and Unlimited add IP address, approximate location, device and browser.
Can I Add Discounts, Due Dates And Late Fees?
Yes. Invoices support due dates, a percentage or flat discount and an optional late fee with its own label.
Do Recurring Invoices Send Automatically?
No, you stay in control. A recurring invoice creates a draft on your schedule, and you review and send it. Recurring invoices are on every plan.
Can QuickBilling Remind Clients To Pay?
Yes. When you email an invoice, you can switch on reminders the day before and two days after the due date, plus optional 7- and 14-day follow-ups.
Is There An Invoicing API?
Yes. A REST API with an OpenAPI description. API keys come with the Unlimited plan, and each key belongs to one workspace.
Is QuickBilling E-Invoicing Software?
It sends every invoice electronically, as a link and a PDF. It doesn’t create structured e-invoices such as XRechnung, ZUGFeRD or Factur-X, so it isn’t electronic invoicing software in the EN 16931 sense.
Is QuickBilling Automated Invoicing Software?
In part. Recurring invoices are prepared as drafts on your schedule, reminders go out before and after the due date, and customers and line items carry over. You still review and send each recurring invoice.
Can I Print My Managing Director, Register Court And VAT ID On The Invoice?
Yes. In your billing profile you enter managing director(s), registered seat, register court, register number and your VAT ID. Switch on “Show company details in the footer” and QuickBilling prints your company, bank and tax details in the page footer; it is on by default for German invoices. Which details your invoice needs is a question for your accountant.
