01PRICING
A price nobody can rewrite.
The displayed amount is computed by the server from your grid: material, surface, metres of edging, hardware, labour, margin. The browser computes nothing, it asks. At checkout the price is recomputed and compared: the slightest gap and the order is refused.
- Price grid and purchase costs are never sent to the browser.
- Checkout re-comparison: any gap blocks the payment.
- Your margins never leave your instance.
