Assign the three business roles
What the scheme requires
The Installer Operating Requirements define three roles every certified business must fill: a Licensee who signs the Installer Agreement, a Main Contact for scheme communication, and one or more Technical Supervisors. Your certification body will expect you to name them and show they are genuinely part of how the business runs. MCS guide to the new business roles (MCS)
The Payaca feature
Every Payaca user has exactly one defined system role, chosen from Payaca's fixed set (Super Admin, Admin, Sales Manager, Sales Agent, Restricted Sales Agent, Field Agent), each a bundle of what that person can reach and do. Your MD, office manager and engineers each see the parts of the operation their role covers, so who holds which responsibility is a fact in the system, not a line in a document.
