Contracts
Keep the deal beside the number
Record the agreed terms once, then link billing, service and payment activity to them. When a number changes, you can see which contract and recorded event produced it.
The contract is where the money story starts
At a company I ran before Economico, billing problems often began when the signed terms lived in a different place from the billing system. A renewal, service period or custom term could change what a customer owed, while the spreadsheet kept an older answer. The contract needs to remain visible when the invoice and report are read later.
Record activity against the terms you accepted
Your agent records a contract from the terms you agreed. It can then record acceptance, billing, service, usage and payment against that contract. Each recording has a receipt and a statement that cannot be edited later, linked to the source documents you provide. Amendments keep the earlier terms in the history instead of overwriting them.
Record the signed Acme service terms, then show which activity created this month's amount due and which source document supports it.
The agent does not decide what the contract means
You still supply and approve the agreed terms and evidence. Economico does not negotiate, sign or interpret legal language for you, and it does not email invoices to customers. What it gives you is a ledger record that keeps the agreed terms, the activity and the financial effects connected.
