Questions, corrections and workbook support
If you need help with a BuildCostSheets resource, found an error in a calculator or want to ask about a workbook, contact the site directly at hello@buildcostsheets.com.
Corrections and updates
If you notice a broken link, unclear wording or a calculation issue, send the page URL, what looks wrong and what you expected to see. Correction requests are welcome.
Commercial questions
Use the same address for licensing questions, partnerships or product-related business inquiries. BuildCostSheets does not accept guest posts or low-quality link placements.
What helps us respond faster
- The exact page URL or product name.
- A short description of the problem or question.
- Your local assumptions if the issue involves taxes, labor burden or pricing logic.
- A screenshot if the workbook or calculator display looks wrong.
Response expectations
BuildCostSheets is a small independent site, so replies are handled manually rather than through a support desk. The audience is primarily English-speaking contractors and estimators, but support messages are reviewed from Argentina business hours. Clear emails with the page URL and issue summary are much easier to resolve quickly.
If a page needs a factual correction, that request gets priority over general brainstorming. The goal is to keep published resources trustworthy, not just available.
What this inbox cannot do
BuildCostSheets can clarify how a calculator or workbook is meant to work, but it cannot verify every contractor's local wage law, tax treatment, insurance rule, production rate or contract clause. Final project pricing decisions always belong to the estimator and business owner.
