Best Invoice Software for Virtual Assistants in 2026

Virtual assistants often work with multiple clients on retainer. Getting invoicing right from the start means predictable income and no monthly payment chasing. Here are the best tools.

What VAs specifically need from invoicing software

• Recurring monthly invoices, most VAs work on monthly retainers
• Service agreements that define scope, hours, and what happens with unused time
• Payment links clients can use without a PayPal account
• Automatic reminders for clients who consistently pay late
• Professional invoices that match the quality of the service they provide
• Ability to invoice in multiple currencies for international clients

1. Becflow - Best for VAs who want simplicity

2. Wave - Best free option

Wave is free and handles basic invoicing well. If you are just starting out as a VA and want something with no monthly cost, Wave works. The main downsides are no automated reminders and transaction fees on card payments.

3. FreshBooks - Best if you track hours

FreshBooks has time tracking built in, which is useful if you bill by the hour. It also handles recurring invoices. Starts at $19/month but limits clients on the cheapest plan.

The VA invoicing mistake that kills cash flow

Most VAs invoice at the end of the month for work they did throughout the month. This means you are always waiting 30-45 days to get paid for work you did at the start of the month. The fix is simple, invoice at the beginning of the month for the upcoming month's retainer. You get paid before you do the work, not after.
