What is an Online Invoice Generator?
An online invoice generator is a cloud-based tool that creates professional invoices through a web interface or mobile app. Instead of manually formatting documents in Word or Excel, you enter information into pre-designed forms that automatically calculate totals, apply your branding, and generate polished, payment-ready invoices in seconds.
How Online Generators Work
Create Account & Add Business Info
Sign up and enter your business name, address, logo, and payment terms once. This information automatically appears on every invoice you create.
Add Clients to Database
Enter client information once and save it. Future invoices auto-fill client details from your saved database—no retyping client addresses or emails.
Create Invoice from Template
Choose a client, select a professional template, add line items for services or products, and the system automatically calculates subtotals, taxes, and final totals.
Send & Track
Send the invoice via email directly from the platform, track when clients open it, receive notifications when they pay, and send automated reminders for overdue invoices.

Create Your First Invoice FreeFrequently Asked Questions
Are online invoice generators really free?
Many online invoice generators offer free tiers with basic features like creating and sending invoices. However, advanced features like payment processing, recurring invoices, automated reminders, and multi-user access typically require paid subscriptions. QuickBillMaker offers a free tier for up to 5 invoices per month, perfect for low-volume users or testing the platform.
Is it safe to use an online invoice generator?
Reputable online invoice generators use bank-level encryption (256-bit SSL), secure data centers, and regular security audits to protect your information. Look for platforms with SOC 2 compliance, GDPR compliance for EU clients, and clear privacy policies. Avoid generators that do not use HTTPS or have questionable data practices. Always check reviews and the company reputation before entering sensitive business data.
Can I customize the look of invoices from online generators?
Yes, most modern online invoice generators offer extensive customization options including uploading your logo, choosing color schemes matching your brand, customizing fonts and typography, adding or removing fields, and adjusting layout and spacing. Premium platforms often provide CSS editing for advanced customization. QuickBillMaker offers brand customization even on the free tier.
Do online invoice generators work on mobile devices?
Most web-based invoice generators are mobile-responsive, meaning they work in mobile browsers. Many also offer dedicated iOS and Android apps for enhanced mobile functionality like camera receipt scanning, push notifications, and offline access. Mobile apps are particularly useful for field service professionals, contractors, and anyone who invoices clients on-site.
Can I send invoices directly from the generator?
Yes, online invoice generators typically include email delivery features that send invoices directly to clients from the platform. You can usually customize the email message, set CC/BCC recipients, schedule send times, and track when invoices are opened. Some platforms also offer SMS delivery, client portal access, or integration with your existing email provider.
What happens to my data if I stop using the service?
Reputable platforms allow you to export your invoice data in standard formats like PDF, CSV, or Excel before canceling. Some offer grace periods to download data after subscription ends. Always check the data export options and data retention policies before committing. QuickBillMaker allows full data export at any time, and you retain access to your data even after downgrading to free tier.
