Source facts are permanent.
Original records and source-derived financial facts are preserved and protected from casual mutation.
Source-led financial history
Your financial history should outlive your software.
BuiFund is a durable financial archive and source-ledger system designed to preserve, normalize, reconcile, and reuse financial history from original institution-issued records.
Source → Ledger → Anywhere
Original records
Statements and source documents remain the evidence.
Canonical ledger
Normalized facts with provenance and reconciliation.
Replaceable applications
APIs, analytics, accounting tools, and future systems.
Built for permanence
Preserve the facts. Replace everything else.
Financial institutions already produce the documentary evidence. BuiFund keeps that evidence connected to a durable, machine-readable history rather than locking the history inside one application.
Verifiable provenance
Source identities, parser information, and reconciliation keep normalized facts traceable to their origin.
Reusable history
Applications can change without forcing financial history to be recreated from scratch.
Core principles
Designed around ownership of your history.
BuiFund separates documentary evidence, normalized financial facts, human interpretation, and the applications that consume them.
Interpretation is replaceable.
Categories, tags, notes, mappings, and other interpretation can evolve without rewriting historical facts.
Applications are disposable.
Web frameworks, accounting systems, databases, and analytics tools remain consumers rather than owners of the history.
