Restaurant Costing Spreadsheet vs Software: When the Spreadsheet Breaks
A sober comparison of spreadsheets and purpose-built costing software for small food businesses.
Spreadsheets are a good beginning. They are flexible, cheap, and familiar. They also become fragile when recipes, supplier prices, packaging, staff access, and AI imports enter the picture.
Where spreadsheets work
A spreadsheet can be excellent for a small menu, a single operator, and stable prices. It gives control and makes the math visible.
The problem starts when more people need access, invoices change weekly, and recipes contain other recipes.
Where software earns its place
Software helps when the workflow needs permissions, versioning, price history, supplier comparison, AI extraction, staff access, and structured review.
Karu is not trying to replace thinking. It is trying to remove the repeated data cleanup that keeps operators from thinking clearly.
The migration should be gentle
The best path is not forcing users to rebuild everything manually. They should be able to upload existing spreadsheets, menus, invoices, and recipes.
AI can turn that starting mess into drafts, and the user can approve the records that matter.
Operator checklist
Use spreadsheets while the workflow is simple.
Move to software when versioning and permissions matter.
Import existing files instead of starting from zero.
Keep approved data separate from AI drafts.
