We needed this to maintain accounts for our B2B products, so we came up with https://github.com/RealImage/QLedger https://github.com/RealImage/QLedger - we deploy the ledger as an internal service (Go+Postgres+Docker) and write a 'Bank' over it for each business model that we have (two-party / multiparty). Works great so far, and is pretty solid. Would love feedback. We haven't yet hit the scale where postgres can't sum up the transactions in time and we need to maintain caches, but we're willing to look at ideas for that.
