# Billing Operations with BlueRockTEL

2023-07-01 By BlueRockTEL Team

## Two Billing Modes

BlueRockTEL's Events menu allows you to run billing operations. Two modes are available, each with a distinct purpose.

## Pre-Production

Pre-production lets you simulate the next billing campaign **without generating or sending real invoices**. The operation runs on a copy of your database.

By default, it corresponds to the current month's batch, or the next chronological batch if you use multi-batch billing.

### What You Can Verify

For each simulated invoice, pre-production displays:

- Invoice number, customer record and billed sites
- Customer account and company name
- Gross and net totals
- Payment method
- Charge breakdown: one-time fees, recurring subscriptions, consumption and prorated amounts

You can view individual invoice PDFs and consumption statements.

### Correct Before Launching

If anomalies are detected, you correct the affected customer records and run another pre-production. This cycle can be repeated as many times as needed until everything is validated.

It is also possible to simulate billing for the **following month**, which allows you to anticipate and correct any configuration errors before the first of the month.

An email notification confirms when the operation is complete.

## Production

Once all data has been verified and validated in pre-production, you launch **production**. This operation:

- Generates the final PDF invoices
- Sends them by email to customers
- Initiates SEPA direct debits for active mandates

Production runs only once per cycle, after pre-production validation. This is the guarantee of reliable, predictable billing.
