Catch the charge that
never made it onto the invoice.

Droplet traces every gap from contract to usage to billing to payment, so billing teams see exactly where a charge went missing and what to fix.

Case RA-014, usage overage not invoiced. The contract check passes, with overage of $0.002 per unit above 8M, and so does usage, with 12.41M units metered. Billing fails: the overage line is missing from the invoice. Payment was collected as billed. Open findings: Acme Corp, $8,420 per month; Northstar Health, $27,600; Atlas AI, $3,360 per month.

Find the line that went missing.

Most billing errors are small and quiet. Droplet finds them line by line.

Spot usage that was never invoiced

Compare what was metered with what each invoice actually charged.

An Acme Corp invoice for September 2026: the per-seat price is invoiced, the usage above 8M units is missing from the invoice, and the discount billed is 5 points over the contract.

Run the same controls every time

Standard detection controls check pricing, usage, discounts and commitments on every audit.

Controls by exposure: usage to invoice coverage, $48.2K, investigation; contract to billed rate, $39.7K, warning; minimum commitments, $32.0K, warning; seats to subscription quantity, $14.1K, passing.

Fix it with a corrective action

Corrective actions and approvals keep every fix on the record.

27 findings have a corrective action open. Next action: issue a corrective invoice for Acme Corp, due in 2 days. 11 findings are closed and their recovery verified.

From missing line to corrective invoice.

Droplet shows the failing step; your billing team makes the fix.

  1. Connect billing and usage

    Link Stripe, your contracts and your usage data. Droplet only reads them.

  2. Check every line

    Line items are compared with contract terms and metered usage on each audit.

  3. Trace the gap

    Contract, usage, billing and payment are checked in order, so the failing step is obvious.

  4. Correct and verify

    Open the corrective action, issue the invoice in your billing system and track it to closed.
