Fund administration
Fund administration that proves every number
Your NAV, koers, fees and high-water marks are computed in exact decimal arithmetic, checked against four reconciliations, and locked so they cannot change behind your back. Tap any figure to see the formula, the inputs and the month it came from.
No credit card. Nothing is charged until your first 30 days are over.

What you can rely on
- Exact decimal arithmetic, computed in the database
- Four reconciliation checks before every lock
- Locked months cannot be quietly edited
- Dutch and English, statements included
Why FundFlow
Six things a spreadsheet cannot do
The short version. The long version is on the page about it.
The close is one guided flow
Balances, flows, costs, checks, lock. Five steps ending in a review that shows what will be written.
Figures are computed, never typed
NAV, koers, fees and high-water marks come out of one calculation in exact decimal arithmetic.
It checks itself before you lock
Four reconciliations run every time, and a failing one blocks the month rather than warning you.
Every number explains itself
Open any figure to see its formula, the inputs it used and the month it belongs to.
Statements go out from the same screen
A PDF per participant, in Dutch or English, with a delivery record per recipient.
A locked month stays locked
Immutable at the database level. Reopening is administrator only and leaves a written reason.

The hero flow
What a monthly close looks like
Five steps. The same five every month, in the same order, on a phone if that is what you have with you.
Enter the month-end balances
One card per bank and brokerage account, with last month’s figure shown behind yours and a running total as you type.
Confirm the money that moved
Every pending deposit and withdrawal for the month, confirmed or excluded one at a time. The step will not advance while anything is undecided.
Book costs and dividends
Add an expense, record a fee payment, or book a dividend with its country’s withholding-tax rate prefilled and allocated across participants by ownership.
Compute and review
The engine runs and shows you the gross return, the koers per series, the fees and the four reconciliation checks: with the difference and the threshold for each.
Confirm and lock
Lock the month yourself, or send it for a second person to confirm first. After that it is immutable: reopening is admin-only and needs a written reason.

- Pay per fund, so a second fund only costs you when you run one
- Yearly is €1,428 per fund, which is 20% off
Control
Built so a wrong number cannot go quiet
Fund administration is not really a data-entry problem. It is a problem of knowing that what you sent was right.
Locked months stay locked
Once a month is locked the database itself refuses to change it. Corrections happen by reopening it (admin only, with a written reason) or in the current month, the way a fund administrator would do it anyway.
Two people, if you want two people
Turn on NAV confirmation and the person who prepares the month cannot be the person who locks it.
Nothing arrives without a record
Every participant change is written to a history you can search. Every statement send is a delivery row with its own status.

Where this came from
Built for one fund, then opened up for others
FundFlow was developed to run the monthly administration of one fund: three fee series, fourteen participants, and a cycle of balances, fees, high-water marks, reconciliation and statements every month. Every rule in the engine was checked against how that fund actually worked, to the cent. Once it ran that fund properly, we opened it up as a product, because the job is the same for every manager doing it in a spreadsheet. It is built in the Netherlands.
Before you ask
The four questions everyone asks
What does FundFlow cost?
€149 per fund per month, or €1,428 per fund per year, excluding VAT. The price does not change with the size of the fund, the number of participants or the number of people who log in. The first 30 days are free and no payment details are collected to start.
I already have years of history. Can I move?
Yes. You anchor the fund with one opening month: the koers per series, the high-water marks and each participant’s units or value at that date. From the month after that you close normally in FundFlow. Months before your anchor month stay where they are. FundFlow does not reconstruct them.
What happens if I close a month wrong?
The reconciliation checks are there to stop most of it: a failing check blocks the lock. If something still needs correcting after a lock, an administrator can reopen the month with a written reason, or you can post a correction in the current month. Both are recorded.
Is it in Dutch?
Fully. The app, the emails and the PDF statements your participants receive are all available in Dutch and English, and the language of a fund’s reporting is a setting per fund.
Your next month-end could be the last one in a spreadsheet
Set up a fund, enter one opening position, and close a month. Thirty days is more than enough to find out whether the numbers agree with yours.
No credit card. Nothing is charged until your first 30 days are over.
