# Facility Billing

Facility billing lets facility staff create and manage medical invoices from the facility panel. Invoices are stored by `0r-ambulancejob` first, so the feature can work even when you do not use a separate billing/payment resource.

Custom external billing calls are isolated in `modules/billing/server.lua`. By default, the bridge detects:

* `okokBilling`
* `qb-phone` for QBCore/Qbox servers

If no supported billing resource is started, invoices stay manual and staff can mark them paid from the facility panel after role-play payment.

## Configuration

Billing settings are inside `config/facility.lua`:

```lua
Config.facility.runtime.billing = {
    enabled = true,
    depositPaidInvoicesToFacilityAccount = true,
    presets = {
        { key = "revive",     label = "facility_billing_preset_revive",     amount = 750 },
        { key = "treatment",  label = "facility_billing_preset_treatment",  amount = 500 },
        { key = "surgery",    label = "facility_billing_preset_surgery",    amount = 2500 },
        { key = "scan",       label = "facility_billing_preset_scan",       amount = 900 },
        { key = "blood_test", label = "facility_billing_preset_blood_test", amount = 350 },
    },
}
```

* `enabled`: enables or disables facility invoice creation.
* `depositPaidInvoicesToFacilityAccount`: when `true`, paid invoices are deposited into the facility account.
* `presets`: quick invoice options shown in the facility billing UI.

## Database

Billing uses the `0resmon_ambulance_facility_invoices` table.

{% content-ref url="/pages/arRnnfdsNTlR4P4iiumo" %}
[Database SQL](/0resmon/0r-resources/0r-ambulancejob/setup-and-database/database.sql.md)
{% endcontent-ref %}

## Custom Payment Sync

When a custom billing resource confirms payment, call this from server-side code:

```lua
TriggerEvent("0r_ambulancejob:server:billingPaid", {
    invoice_id = 12,
    -- or external_invoice_id = "custom-bridge-id"
})
```

Client-triggered calls to this event are ignored.

## Server Exports

```lua
exports["0r-ambulancejob"]:CreateFacilityInvoice(payload)
exports["0r-ambulancejob"]:MarkFacilityInvoicePaid(invoiceId, options)
exports["0r-ambulancejob"]:CancelFacilityInvoice(invoiceId, reason)
exports["0r-ambulancejob"]:GetFacilityInvoices(facilityId, filters)
exports["0r-ambulancejob"]:GetPlayerUnpaidFacilityInvoices(identifier)
```

`CreateFacilityInvoice` accepts:

```lua
{
    facility_id = 1,
    patient_source = 23,
    amount = 750,
    preset_key = "revive",
    reason = "Revive"
}
```

You can also pass `patient_identifier` and `patient_name` instead of `patient_source` when the patient is not online.
