Paymo – Best for Freelancers & Project-Based Work
Paymo focuses on freelancers and small teams who bill by the hour or manage client projects.
Unlike pure invoicing tools, Paymo integrates time tracking and project management directly into the billing process.
This makes it a strong choice for designers, consultants, agencies, and service-based businesses that need accurate time-based invoices.
While it doesn’t offer a permanent free plan, the free trial allows users to fully test the platform before committing.
Invoice Ninja
Invoice Ninja is one of the most flexible invoicing tools on the market.
What makes it stand out is its generous free plan combined with advanced features such as recurring invoices, client portals, and even the option to self-host the software.
It’s especially well suited for freelancers and small businesses who want full control over their invoicing process without monthly costs.
As your business grows, paid upgrades unlock automation and advanced integrations.
Zoho Invoice
Zoho Invoice is designed for businesses that want more than just basic invoicing.
As part of the Zoho ecosystem, it integrates seamlessly with CRM, accounting, and project management tools.
It’s a great option for companies that plan to scale and need automation, tax compliance, and professional workflows.
Zoho Invoice can be used on its own, but unlocks its full potential when combined with other Zoho products.
