How 5 Minute Estimate works.

No desktop apps, no complex login portals, no CRM onboarding. Everything happens inside WhatsApp.

Step 1

Send your project to Max

Open WhatsApp and message Max. You can send PDF drawings (planning or building regs), structural calculations, site photos, sketches, or record a 60-second voice note describing the job. Max reads what you send and starts building the scope.

Step 2

Max checks scope and flags gaps

Max reviews your drawings and notes, identifies discrepancies between plans, checks for common risk items (party wall, build-over agreements, planning conditions), and asks 2–3 quick questions to clarify anything missing before drafting.

Step 3

Review your draft documents

Within minutes, Max sends back your branded PDF documents: estimate, quote, material take-off, programme, or draft H&S pack. Every document shows assumptions and gaps clearly flagged. You review, adjust, and send to your client. Final review is your responsibility.

Supported inputs

  • Drawings: PDF, PNG, JPG — planning drawings, building regs, structural engineers' details
  • Audio: WhatsApp voice notes describing the job in your own words
  • Photos: Site photos, existing conditions, handwritten sketches with dimensions
  • Documents: Client emails, tender specifications, Word documents, Excel price lists

What you get back

  • Structured estimate or quote with itemised sections
  • Material take-off or quantified schedule
  • Estimating-stage programme where applicable
  • Draft H&S documents (RAMS, method statements) — require competent-person review
  • All outputs are drafts requiring builder review before issue

Turnaround and limitations

Most drafts are returned within 5 minutes of receiving your information. Complex projects with multiple drawings or unusual scope may take a few minutes longer. Max works best with clear drawings and scope descriptions; very vague or incomplete briefs may need additional clarification before drafting can begin.

Max is an estimating assistant, not a substitute for professional judgement. Always review assumptions, quantities, rates, and terms before sending to your client.
