Bridge Town applies the discipline of version control to financial models. Every assumption, formula, and output is committed to a project history — reviewable, diffable, and rollback-able. This page explains what git-versioned financial planning software means and why it matters for FP&A teams that need to answer "what changed and why" without a manual audit trail.
Try Bridge Town FreeWithout version control, answering this requires tracking down who edited the model, when, and what they changed — often impossible when models live in shared drives. With Bridge Town's version history, every change is timestamped and attributed. The diff view shows exactly which assumptions or formulas changed between any two versions.
FP&A teams commonly manage budget scenarios by duplicating spreadsheet files: "budget_v3_final_FINAL_USE_THIS.xlsx." Bridge Town uses branches — each scenario is a clean branch off the main plan. Scenarios can be compared with an output diff and merged when the preferred version is selected.
Regulated industries often need to demonstrate that financial models are controlled and auditable. A version-controlled model in Bridge Town provides an immutable record of every change — who made it, what it was, and what the model produced before and after.
Bridge Town stores financial model logic as Python files inside a versioned project. The project structure is similar to a software code repository — every change is committed with a message describing what was updated and why. The platform's AI agent handles committing changes as it works; finance users see a clean history timeline without needing to interact with version control commands directly.
Versioned operations in Bridge Town
In software engineering, git is a version control system that tracks every change to code files — who changed what, when, and why. Git-versioned FP&A software applies the same discipline to financial models: every change to a model assumption, formula, or structure is recorded with a timestamp and a description. Teams can view the full history of a model, compare any two versions, roll back to a prior state, or branch the model for scenario analysis.
Bridge Town stores financial model logic as Python files inside a project. Every change is committed to the project history, which functions like a git repository. Finance teams can view a timeline of model versions, see a diff of what changed between any two runs, and create branches for budget scenarios or sensitivity analysis. The history is permanent and append-only — nothing is lost.
Financial models often change during planning cycles: assumptions get updated, formulas get corrected, and scenarios get added. Without version control, teams manage this through file copies, email threads, and manual change logs. This makes it hard to answer "why did this number change?" or "what was our assumption last quarter?" Version control makes every change reviewable and every question answerable from the project history.
Yes. Bridge Town abstracts the version control layer. Finance analysts describe model changes in plain language, and Bridge Town handles committing and tracking the changes. The version history is exposed as a simple timeline in the interface — not as a command-line tool. Teams do not need to know git commands to get the benefits of a versioned workflow.
Yes. Each planning scenario is a branch in the project history. Teams can run base case, upside, and downside scenarios as separate branches, compare outputs across branches, and merge the preferred scenario into the main plan. This replaces the common practice of managing scenarios as separate files or tabs in a spreadsheet.
Bridge Town is free to start. Your first model is committed to a full version history from the beginning.
