Wave also aligns with accounting standards and allows users to reconcile accounts with ease. 

Wave is ultimately a great entry-level tool when it comes to the best free invoicing software, and you can't really beat a free solution when you're starting out.

QuickBooks allows businesses to track their spending, send and customize invoices, and run reports for better business insights.

  • A wide range of accounting features
  • Income and expense tracking
  • Basic reporting

More than Just Invoices 

5. HoneyBook (web, iOS, and Android compatible)

HoneyBook is a CRM that can also handle the basics of invoicing (including invoice templates, payment notifications, profit and loss reports, and basic expense tracking). Its strength lies in its ability to do several business-related tasks rather than focusing on finances alone. 


  • User-ease and quick onboarding for new clients
  • Manages invoicing, payments, integration, and project workflow
  • Streamlined pipeline system, which helps to turn leads into clients
  • Supports Zapier, meaning it integrates with various online management tools.

  • Pricier than some other small business client relationship management platforms
  • Manual and pretty basic expense tracking, which may become arduous. 


HoneyBook offers customers a 7-day free trial and then has several plans available thereafter. Plans start at $16 per month for the starter plan and go right up to $66 for the premium plan. The latter allows for unlimited users, making it a better option for businesses with multiple employees needing to access invoicing tools. 

Why Choose Practice?

The Bottom Line 

Choosing the right invoicing software will depend on your business and unique payment management criteria. What works for a medium-sized law firm or an advertising agency with 50 employees won't work for a one-person coaching consultancy. Consider what you need from your invoicing software and choose a plan and service provider that tick all the boxes.
