Working files for Tradex Trading & Contracting.

• tradex-flow.html: the project flow from cost estimate to customer and subcontractor progress billing, with owner, Odoo document and control for each step, plus a monthly progress log per project.
• tradex-estimate.html (served at /estimate): project cost estimates. Keep a price list of materials and subcontractor items (typed in or imported from Excel/CSV), build the cost of one indoor unit, multiply by the number of units, add overhead (15%) and indirect cost (35%) on direct cost, and price for a 20% margin on the sales price. Rates can be changed per estimate, and each estimate exports to Excel with live formulas.

Using it

Open tradex-flow.html or tradex-estimate.html in a browser and sign in (one account works for both). The first time, choose Create an account, confirm the email Supabase sends, then sign in. Only emails on the editors list can see or change the data.

Everything is stored in the Supabase project "live artifact" (eu-central-1). Each change is saved when you press Save and logged with who made it and when; open History on a step to see its past versions.
