Is August free landlord software?

Yes. August has a genuinely free plan, not a trial that expires. You can manage your properties at no cost for as long as you like. Paid plans start at £8.99/month (Growth) for landlords who want additional features like advanced reporting and unlimited document storage. Portfolio (£14.99/month) and Portfolio+ (£29.99/month) are available for larger portfolios that need full control.
