Timshal vs. spreadsheets for financial modeling
Spreadsheets are the most flexible tool in finance, and for a quick analysis nothing beats them. But a company's operating model is not a quick analysis. It grows every month, more people depend on it, and the cost of a broken formula grows with it. Here is where spreadsheets strain, and what changes in a dimensional model.
Copied formulas vs. formulas written once
In a spreadsheet, adding a product or region means copying rows and hoping every formula followed. In Timshal, product and region are dimensions: a formula is written once and applies to every member, and a new member picks up the logic automatically.
Pasted actuals vs. connected data
Spreadsheet models are refreshed by exporting from the accounting system and pasting, every month. Timshal connects to QuickBooks Online, payroll systems, Google Sheets and BigQuery and refreshes on a schedule or on demand.
File copies vs. scenarios and versions
A spreadsheet scenario is usually a copy of the file, and the copies drift apart. In Timshal a scenario stores only the assumptions you changed, and the rest follows the base case. Version history saves the model as you work, and you can roll back to any saved version.
Emailed files vs. controlled access
Instead of emailing a workbook, you give people Viewer or Editor access, or share a read-only link scoped to one view for investors. One person edits at a time, so changes never collide, and viewers are unlimited.
Asking questions of the model
Timshal's assistant answers questions about your model from its computed values, such as what drove a change or where a number comes from. With the AI add-on and your organization's own OpenRouter account, it can also make edits. The same add-on lets AI tools such as Claude work with your models through Timshal's MCP server.
The honest trade-offs
There is no one-click Excel import: you rebuild the model, which is also a chance to give it a cleaner structure. A spreadsheet is still the right tool for a one-off calculation. And you can always export a model to a formatted Excel workbook when someone needs a file.
