Connect your flows.
FairFlow ingests your accounts, grants and contributions. It pilots traceability, it never replaces your bookkeeping.
Made with Bonaub / For nonprofit finance teams
Every euro, traced to its source.
Mixed grants land on the same account. FairFlow untangles them, linking every expense to its funder and project, so nonprofits can prove where the money went instead of chasing a spreadsheet.

About the app
A SaaS platform for nonprofits.
FairFlow pilots the financial transparency of associations and nonprofits: it links mixed grants, membership fees and own revenue to their project and their source, in order of funding constraints.
Reconcile shared accounts between members, generate a self-contained report per funder, and stay anchored in the Belgian law on subsidies. FairFlow sits above your accounting; it never replaces it.
From mixed funds to a clear answer
The engine proposes the cascade and flags the risks. The decision stays with you.
FairFlow ingests your accounts, grants and contributions. It pilots traceability, it never replaces your bookkeeping.
A deterministic engine assigns every expense to its funder and project, in order of constraints, and flags clawback risk early.
Validate the proposed allocation, then send each funder a self-contained, replayable report of their own scope.
