Excel vs Software for Interior Design Estimation
When a spreadsheet is enough for interior quotations, and when dedicated estimation software saves time and errors.
Where Excel works
For a solo designer doing a few projects a year, a well-built spreadsheet can be enough.
Where it breaks down
Copied formulas break, rates drift between designers, versions multiply, and approvals and payments live elsewhere. Software keeps the rate card, quote versions, approvals and payments in one place.
