The honest answer: a few hours of committee time, mostly spent finding documents you already have.
The work is not technical. It is gathering what the society already holds and agreeing the numbers you are starting from.
Numbers, owners, area, and whether each is owner-occupied or tenanted.
What you bill and how each is worked out. If it is in the bye-laws, that is enough.
What each member owed on the changeover date. This is the number worth getting right.
The registration certificate, society PAN, and the bank account members will pay into.
We verify the society’s registration and bank account before any bill goes out — the payee name members see is the one the bank returned, not one typed in.
The first bill run is checked against what you would have issued yourself, so errors surface before members see them.
Bills go out on schedule and the committee moves to reviewing rather than producing.
A platform that lets anyone put a bank account in front of a society’s members is a fraud waiting to happen. We check first, every time, and block communications if the account name does not match.
On a managed plan a dedicated accountant does the work and your committee approves it.
