Hello, Welcome to Microsoft Community.
Thank you for your inquiry, you are looking for some advice on offline accounting software.
Unfortunately, due to community restrictions, I cannot offer you any third-party software recommendations.
However, based on my personal advice, if the accounting software you were using can work offline, it's best to stick with it to keep the learning curve low.
If you are using it for work, you can discuss with your colleagues, usually everyone's opinions can give you some inspiration.
Hope you can find the right software.
