Frequently Asked Questions
Everything you need to know about BuildNFO construction calculators.
What is BuildNFO?
BuildNFO is a construction calculator suite for WordPress with 180 calculators across Free, Pro and Enterprise versions — covering concrete, steel, masonry, finishing, MEP, utilities and full project cost estimating.
What is the difference between the three versions?
Each tier is cumulative. Free has 30 core calculators. Pro adds 40 professional estimating tools (70 total). Enterprise adds 110 more including building-cost, commercial and AI workflows (180 total).
How do I add a calculator to my site?
Use a shortcode:
. Paste it into any page or post and the calculator renders automatically. It works with any theme or page builder.
Are the calculations accurate?
All formulas are deterministic and use standard construction conventions. Always verify results against your local building codes and project specifications before final use.
Do the AI features need an API key?
Yes. AI, Picture and Map calculators work as manual estimators out of the box. For automatic extraction from plans or photos, you connect your own Anthropic Claude or OpenAI API key. No AI credits are included.
Is it one-time payment or subscription?
Both. You can buy Pro or Enterprise once for lifetime use, or subscribe monthly for a lower entry price with ongoing updates.
Where can I buy Pro and Enterprise?
Pro and Enterprise are available on CodeCanyon and directly via Freemius on adnanthemes.com. Contact us for enterprise or multi-site licensing.
Can I upgrade later?
Yes. Start with Free or Pro and upgrade anytime — all calculators and settings carry forward.
