Understanding Your Monthly Security Invoice Breakdown

This article is for Clients.

Your monthly security invoice in Attlock is more than just a total — it's a detailed record of every guard hour, site, and service charge for the billing period. Understanding how to read it helps you verify accuracy, spot discrepancies, and have informed conversations with your security provider about costs.

Where to Find Your Invoice

1. Log in to the Attlock client portal.
2. Go to Billing in the left navigation menu.
3. Select the invoice you want to review from the list. Invoices are listed by billing period, most recent first.

Invoice Header

The top of each invoice shows:

• Invoice number — a unique reference for this billing period
• Billing period — the start and end dates covered (typically the 1st to the last day of the month)
• Due date — when payment is expected
• Account name and address — your registered company details
• Security provider — the company providing your guards

Line Item Breakdown

The body of the invoice is divided into line items. Each line represents a specific charge:

Standard Guard Hours

This is the base charge for scheduled guard hours at each site. The line item shows:

• Site name
• Number of hours billed
• Hourly rate
• Subtotal for that site

If you have multiple sites, each site appears as a separate line item so you can see exactly what you're paying per location.

Overtime Hours

If guards worked beyond their scheduled hours — for example, due to an incident requiring extended coverage — overtime hours are listed separately. Overtime rates are typically 1.5x the standard rate and should be specified in your contract.

Public Holiday Rates

Guard hours worked on public holidays are billed at a higher rate (usually 2x standard). These appear as a separate line item showing the holiday date, hours worked, and the applicable rate.

Additional Services

Any services outside your standard contract — such as a one-off security sweep, event coverage, or emergency callout — appear as separate line items with a description and flat fee or hourly rate.

Adjustments and Credits

If your security provider has applied a credit (for example, due to a coverage gap or a service issue you raised), it appears as a negative line item. Check this section to confirm any credits you were promised have been applied.

Comparing Billed Hours to Actual Hours

Attlock makes it easy to verify that billed hours match actual guard attendance. On the invoice page, click View Attendance Breakdown to see a day-by-day log of guard check-in and check-out times for the billing period. Compare this against the billed hours on the invoice.

If you spot a discrepancy — for example, a guard was billed for 8 hours but the attendance log shows 6 — you can flag it directly from this view.

Raising a Billing Dispute

If you believe there's an error on your invoice:

1. Open the invoice and click Dispute Invoice.
2. Select the line item(s) in question.
3. Describe the discrepancy and attach any supporting evidence (e.g., a screenshot of the attendance log).
4. Submit the dispute.

Your security provider will be notified and has a set number of days to respond. The dispute status is tracked in Attlock so you can follow up if needed.
