Finanzfluss Copilot vs Shift4

Finanzfluss Copilot is a German portfolio and budgeting tracker covering brokerage accounts, dividends, budgets and German investment tax. The feed is sparse and uneven: a tax module for Freistellungsauftrag and Vorabpauschale in December, then a five-day Fixit Week in May where the whole engineering team stopped feature work and closed 144 bugs, then near-silence until the August release adding transaction splitting.

The product is being built out along the specifics of German retail investing — allowance tracking, pre-payment tax estimates, broker-specific asset classes — and the Fixit Week reads as an explicit acknowledgement that UI debt had accumulated faster than it was being paid down. Transaction splitting is a standard expectation in this category, so the current direction looks like closing gaps against established budgeting apps rather than opening new ground.

Given the entries here, the likely next step is more depth in budgeting and categorisation now that a transaction can carry several categories; the feed is too intermittent to predict timing with confidence.
