Local backups, with an online option
Optional paid cloud-backup plans are available in the app. Online backup activation and cloud restores are managed by the administrator.

Add your company, parties and items, then create your first invoice. Your trial status appears inside the app.
Try it with your real workflow.
Eligible new accounts start with a free trial. View paid plans and optional backup pricing in Settings when you’re ready.
Is the download free?
Yes. Download the Windows installer for free. Eligible new accounts receive a trial after signup and email verification. Check the app for your trial duration and expiry date. This is not a lifetime-free plan.
Do I log in on this website?
Your billing workspace is in the Windows app. Download and install OSBS, then sign up or log in there. The website’s Admin link is for the software administrator, not customer login.
Can I use it on my phone or Mac?
This download is for 64-bit Windows PCs. Open this website on your Windows computer to install OSBS. It is not an Android, iPhone or Mac installer.
What happens after my trial?
You can view the available paid plans in the app. When a trial expires, the app limits access to viewing existing records until a subscription is activated.
Are my records stored online?
Your primary business database is on your PC. Account and licence information is handled online. Shared invoice PDFs and optional paid cloud backups also use server storage. Cloud backup is a separate, administrator-managed service.
How do I update an existing installation?
Use the app’s update option or install the latest download over your existing OSBS installation. Keep a verified backup first; don’t uninstall or delete your local application data.
