Invio is a fast, self-hosted invoicing application designed for simplicity and transparency, allowing users to maintain full control over their data and deploy it anywhere. Invoices are rendered as HTML from selected templates and business settings, with PDF generation using wkhtmltopdf and an HTML fallback option. In this step by step guide I will show you how to install Invio on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Invio v2.2.0 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

STEP 16

Now open your browser and type in your HTTPS/SSL certificate like this https://akaunting.yourname.synology.me that you have previously created at STEP 6.
