It depends on how many modules you choose to rebuild — a lean garage system is very different from a full dealership DMS. The tool converts that scope into tokens and person-months; the AI-tooling share is usually only a few percent of the total, while most of the cost is design and testing effort.

If you use most of the features and stay small, an off-the-shelf subscription is often the faster choice. But when you use only a fraction of it, need heavy customization or want to own your data and workflows, rebuilding module by module means you stop paying for what you never touch.

With an AI-assisted workflow for code generation, testing and documentation, TOT estimates savings of roughly 35–50% in effort versus a traditional build. That shortens time to a working version and lowers total cost, though engineers still review each business module.

They are framework-based estimates to help you size a budget, not a fixed quote. Results shift with module complexity, how deeply you integrate with existing dealership or telematics systems, and your data requirements; detailed scoping is needed to confirm the final figure.

The tool gives a cost estimate with a reference price list for each AI plan. It is not an official quote — for a detailed quote on your automotive software (by scope, features and integrations), contact TOT to scope it.
