Key features

Quotes on site, offline

Works anywhere, even with no connection: build and export quotes on job sites and in basements, from the van, in full sun.

Ready material catalog

Breakers, RCDs, cables, sockets, wiring devices, panels, trunking, lighting and labor: add items with a quick search.

Automatic total and PDF

Set quantity and price and the total computes itself, discount and VAT included. Generate the PDF and send it by WhatsApp, email or print it.

Built for electricians

Not a generic management app: items, units and trade logic already in place. Customize catalog and prices the way you work.
