Frequently asked questions

Can I move my Excel estimates into ObraMaestra?
Yes. You can import old estimates and keep quoting from there. You keep your history and your prices.
Does ObraMaestra replace Excel for quoting?
For building and sending estimates, yes: faster and without formula errors. If you still want a sheet, you can export the estimate to PDF.
Is it worth it if the spreadsheet is free?
The sheet does not charge, but each estimate takes hours and one bad cell can cost you the job. ObraMaestra saves that time and those errors; you can start free.
Do I need to know formulas or templates?
No. You describe the job in plain language and the assistant builds the line items, quantities and prices. You never touch a formula.
Are prices updated by country?
Yes. It uses reference prices by country (Chile, Mexico, Colombia, Peru, Argentina and Brazil) so you do not look them up by hand.
