Estimate To Invoice Progress Billing Map

Map progress invoices against the estimate total to keep billed amounts within scope. Preparation only, not an account action.

What to provide

The estimate total and every progress invoice issued against it.

How it works

1. Record the estimate total.
2. Sum the progress invoices issued.
3. Compute the billed percentage and remaining balance.
4. Flag any over-billing and return the map.

The output

estimate_total | invoiced_to_date | pct_billed | remaining | overbilled

Worked fictional example

Fictional estimate totals 40,000 with progress invoices of 12,000, 10,000 and 9,000: billed 31,000, which is 77.5%, leaving a remaining balance of 9,000; any new invoice above that over-bills the estimate.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
