One tool: BIM, 3D plans, takeoff and quotes
SangoImmo replaces a stack of tools — CAD, spreadsheet, estimator — with one offline-first BIM app made for Africa. Design the building, and the same model gives you quantities, cost, a quote, an invoice and a buy list. Free to design and cost; on web, Android and iOS.

Why one model beats a stack of tools
Drawing in one program, taking off in a spreadsheet and quoting in another is where errors and lost hours live. SangoImmo keeps the geometry, the quantities and the money in a single model: change a wall and the takeoff, the cost, the quote and the buy list all move with it. It works offline, on an entry-level phone, and speaks the language of the CFA-franc-zone site (block, ring beam, septic tank, Mobile Money).
