Describe the job or upload the plans. You get a full priced BOQ — sections, quantities, rates — that you then edit line by line, or change by telling the assistant what you want different. Priced against your own rate library where you have one.

Everything here is preliminary — for budgeting, marked draft, and not for construction. Approvals need a registered professional. Bring your concept and its numbers, and get put in touch with one.
Talk to a professionalHow it works
Describe the job
In plain words — or upload the plans and let the app take them off. Add your client, location and markups if it's going out as a bill.
Check the draft, change what's wrong
Every quantity and rate is editable, and nothing is saved until you accept it. Or say what you want different — "use precast slabs", "drop the ceiling" — and see the change before it lands.
Issue it under your own name
Totals roll up to the shilling. Export CSV, a print-ready bill or full bid documents — prepared by you, with your company on it.
Kenyan rate library
Indicative material, labour and plant baselines you can copy and localise to your county. Your own rates stay yours.
Money math you can trust
Section subtotals, overheads, profit and contingency — computed in one audited place, to the shilling. Never floats, never surprises.
Built for the diaspora too
