# Bordereaux and carrier settlements

> Review the monthly carrier report, attest it, and record the remittance.

Carrier bordereaux and state filings are different records.

* **Accounting > Filings** holds one monthly premium bordereau per program.
* **Accounting > State filings** holds one statutory transaction report for each eligible surplus-lines bind, premium-bearing endorsement, or cancellation return with a home state.

See [State filing](https://docs.useunderflow.com/controls/state-filing.md) for the statutory workflow.

## What enters a bordereau

The bordereau is built from the premium ledger, not from the policy's current total. Premium-bearing bind, endorsement, cancellation, and reversal events create immutable ledger rows. Fees and taxes remain separate from gross premium; net due carrier is gross premium less commission.

The booking date decides the program-month. The transaction's effective date can be different. A reversal is a new row that offsets an earlier row; the original is never edited.

For direct-bill business, the carrier collected the premium. The bordereau still reports gross premium and commission, but the carrier-settlement payable is zero; Underflow does not create a remittance from Premium Trust. Agency-bill and MGA-bill transactions contribute their net carrier amount to the payable.

Open **Accounting > Filings** to see every program-month with ledger activity. A current or older period can appear as **Not filed** before its program's deadline.

## Monthly filing

Each program defines how many calendar days after month-end its report stays open, at least one, so a month is never filed on a day it is still taking bookings. Underflow checks due periods daily at 11:00 UTC. The current Cyber program waits three days; another carrier can use a different deadline. Programs with no activity receive no filing. A missed run is caught by the next daily check, and re-running does not create a duplicate.

Filing:

1. Stores the complete, versioned report and its integrity digest.
2. Changes the filing state to **Awaiting sign-off**.
3. Creates a carrier settlement in **Ready**.
4. Prevents new ledger postings into that program-month.
5. Creates a sign-off moment under **Desk > Decisions**.

A late correction cannot be backdated into a frozen period. Record it in an open period so the adjustment appears in the later bordereau.

## Review and sign off

Open the Desk moment, or go to **Accounting > Filings** and select the program-month. The moment takes you to the report; sign-off is available only there. Review the booking date, transaction type, policy, insured, effective date, gross premium, commission, net due, and totals.

Select **Download CSV** for the carrier export. The CSV also includes the immutable transaction ID, submission number, policy expiration, taxes, fees, commission rate, currency, description, and a totals row.

An admin or owner can select **Sign off**. Aurora cannot sign. A filed report is stored once and never rewritten, so the report the member reviewed is the report the signature attests to; Underflow checks the stored digest before recording the signature and refuses a filing whose artifact does not match it. The filing and settlement change from Ready to Signed in one transaction. Repeating the action does not replace the first signature.

> [!NOTE]
>
> The CSV and screen both read the stored filing artifact after filing. They are not regenerated from mutable labels.

The current bordereau workflow does not transmit a report to a carrier. Download and delivery happen outside the workbench.

## Carrier settlement

Open **Accounting > Settlements** to see what the desk owes each carrier by program-month.

| State | Meaning |
| - | - |
| Accruing | The period is open and totals are calculated live from the ledger |
| Ready | The bordereau has filed and totals are frozen, awaiting sign-off |
| Signed | A member signed off the bordereau |
| Paid | An admin or owner recorded the carrier remittance |

After sign-off, admins and owners can select **Mark paid** and add a wire or check reference. Underflow refuses payment while the settlement is only Ready. This records a remittance that has already happened; it does not initiate a bank payment. A positive amount creates one paid carrier-remittance row against Premium Trust. A zero or negative amount closes without a disbursement.
