Every change, approved in writing

The client requested a change over WhatsApp, the architect approved it verbally, and the site manager found out on-site three weeks later — right when it was time to invoice. Plans circulated in different versions over email, and by the end of each phase no one could say for certain who had approved which change, or what it cost.

• A change approved with no formal record turns into a budget argument months later.
• Plans in different versions floating around email is the most expensive way to lose control of a build.

A change-order workflow where every modification is documented, with its cost and schedule impact, and requires the client's digital approval before it reaches the site — with a single version of the plans as the source of truth for the whole team.

A document management service versions every plan and phase budget; each change request goes through a digital-signature approval flow before notifying the site, leaving a traceable record of who approved what and when.
