Metered Usage Overage Cap Recheck

Recheck the overage charge on a metered invoice against the plan cap and per-unit price. Preparation only, not an account action.

What to provide

Plan included units, recorded usage, overage unit price and the invoiced overage.

How it works

1. Record the included units from the plan.
2. Compute overage units as usage minus included units.
3. Compute the overage charge as overage units times unit price.
4. Compare to the invoiced overage and return the difference.

The output

invoice | included_units | usage | overage_units | unit_price | expected_overage | invoiced_overage | difference

Worked fictional example

Fictional plan includes 1,000 units, usage is 1,150 and overage price is 0.10 per unit: overage is 150 x 0.10 = 15.00; the invoice shows 25.00, an overcharge of 10.00.

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.
