InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I'm not 100% sure if it has exactly what you are looking for (although I'm pretty sure it does) but check our ERPNext, it's a full ERP but you can just use the accounting function and I am certain it has this feature I just haven't used it in awhile so I can't check to make sure. It's open source and self hosted https://erpnext.com/
