About
We started with somebody else’s spreadsheet
FundFlow was not designed from a category definition. It was built to run one fund’s monthly administration (three fee series, fourteen participants, a cycle that took an evening), rebuilt until that evening became a quarter of an hour, and then opened up as a product for every other manager with the same job.
No credit card. Nothing is charged until your first 30 days are over.

What we found in the spreadsheet
Everything worked, and nothing was safe. Management fees were right. Performance fees with high-water marks were right. But the totals carried floating-point residue from years of accumulated arithmetic, a row inserted in the wrong place would have gone unnoticed for months, and the only thing standing between a wrong month and fourteen investors was the care of one person on one evening. That is not a criticism of the person. It is what spreadsheets are.
What we decided because of it
Money maths runs in the database in exact decimal arithmetic, never in JavaScript. A month is a unit of truth that gets locked. Every derived figure keeps its inputs so it can explain itself. Reconciliation is not a column somebody remembers to check, it is a gate. And every screen is designed for a phone first, because the person doing this work is not always at a desk when the statements land.
Who builds it
FundFlow is a small software company in the Netherlands. Small enough that the person who answers your email is the person who wrote the code, and that we would rather tell you what FundFlow does not do than find out later that you needed it.
The rules we hold ourselves to
Computed, never typed
If a figure can be derived, you never enter it. Manual entry is reserved for the things only you can know.
One goal per screen
A screen answers one question or completes one task. Anything more becomes its own step.
Numbers get the typographic care
Tabular numerals, consistent precision, and a way to see the working behind every one of them.
Say what it does not do
The feature list on this site is the honest one. If something is not built, you will not read about it here.
