The Verdict
Invoice Ninja wins on cost and flexibility if you're willing to self-host or stay small — it's the better pick for freelancers who need invoicing, quotes, and a client portal without a recurring bill. Harvest wins on polish and team usability, especially if you already rely on tools like Slack, Asana, or QuickBooks and are willing to pay per seat for cleaner time tracking and reporting.
How to switch from Invoice Ninja to Harvest
- 1Export your data from Invoice Ninja via Settings > Account Management > Export, downloading separate CSV files for clients, invoices, expenses, and payments.
- 2Clean up the CSV files to match Harvest's import format, since Harvest requires specific column headers for client and project import.
- 3Use Harvest's CSV import tool (under Settings > Import) to bring in client and project records; invoice history will need to be re-entered or kept as an archive.
- 4Recreate recurring billing manually in Harvest by setting up projects and budgets, since Harvest doesn't automate recurring invoices the way Invoice Ninja does.
- 5Reconnect integrations like QuickBooks, Slack, or Asana directly in Harvest's integration settings to replace any automations you had running through Invoice Ninja.
- 6Invite your team to Harvest, assign seats, and run both tools in parallel for one billing cycle before fully retiring Invoice Ninja.
Invoice Ninja vs Harvest: common questions
How do I export my data from Invoice Ninja before switching to Harvest?+
Go to Settings > Account Management > Export in Invoice Ninja, which generates CSV files for clients, invoices, expenses, and payments. Download each data type separately since Invoice Ninja doesn't bundle everything into one export file. Keep these CSVs as your backup even after migrating, since Harvest's import tools won't pull historical invoice line items directly.
What features will I lose moving from Invoice Ninja to Harvest?+
You'll lose the client portal, proposal/quote generation, and recurring invoice automation that Invoice Ninja includes natively. Harvest focuses on time tracking and simple invoicing tied to hours worked, so anything involving complex billing workflows or client-facing approval flows will need a separate tool or manual process.
Is Harvest's free plan enough for a small team?+
No — Harvest's free plan is capped at 1 seat and 2 projects, so it only works for a solo freelancer testing the product. Any team of 2 or more will need the Pro plan at $13.75 per seat/month, which adds up fast compared to Invoice Ninja's free self-hosted option.
Does Harvest integrate with the same tools as Invoice Ninja?+
Harvest has more native integrations, including Slack, Asana, Trello, Basecamp, and QuickBooks, which Invoice Ninja doesn't match out of the box. If your workflow depends on syncing time tracking with project management tools, Harvest will require less manual setup.
Will switching from Invoice Ninja to Harvest cost more over time?+
Yes, if you were using Invoice Ninja self-hosted for free, switching to Harvest means paying $13.75 per seat/month indefinitely once you exceed 1 user. For a 5-person team, that's roughly $825/year versus $0 for self-hosted Invoice Ninja (excluding server costs), so the switch is a real recurring expense, not a one-time fee.
