Check an estimate before you send it

Open the bill you are about to issue and confirm every position carries both a quantity and a rate. Blank cells and stray zeros are the first thing the validator hunts down, so a quick scan now saves surprises.

Why: A gap you overlook is a gap the client finds first, usually in the meeting. Reviewing the bill yourself means the validation pass confirms good work rather than exposing a hole.

Run the rule sets across the bill and read the traffic-light result. Each error and warning is linked to the exact position, so you can jump to the offending line and fix the cause rather than the symptom.

Why: Missing quantities, zero prices, duplicate lines and rates outside a sane band are cheap to correct today and awkward to explain after issue. The score is your honest go or no-go signal.

Once the bill reads green, export the executive summary alongside the detailed breakdown. The report ships the cost split and the validation outcome in one document.

Why: A report backed by a passed validation is one you can stand behind under questioning. It shows the client not just the total but that the total was checked against rules before it was sent.
