Fixed-price internal tools that replace spreadsheet chaos

Spreadsheets fail when three people edit the same tab, formulas break at row ten thousand, and nobody knows which version is truth. Internal tools fix one workflow: approvals, inventory, scheduling, or handoffs between teams. Lab Twelve prices them as fixed-scope apps—usually Micro or Business tier—after the scope chat names screens, roles, and data. You are buying a deployed tool, not a workshop series.

FAQ

Questions for this build type

We only have a spreadsheet—is that enough?

Bring the sheet. We extract entities and screens in the scope chat. If the workflow is unclear, we will say so before you pay.

Can this integrate with Google Sheets?

One-way import or sync can be scoped as an integration add-on.

What if requirements change mid-build?

Scope lock defines done. New work is a change order or lane ticket after launch.
