Understanding your COEX invoice

Registered beverage manufacturers pay scheme contributions for eligible beverage containers they supply into Queensland.

Your invoice is calculated using the eligible container quantities reported for the relevant period and the applicable scheme price for each material type.

How invoices are calculated

Your scheme contribution is based on:

Scheme prices are stated in cents per container and are exclusive of goods and services tax (GST).

Calculation:

Number of eligible containers reported × applicable scheme price = scheme contribution

For current prices, visit scheme pricing page.

How often will I be invoiced?

Your minimum reporting and invoicing frequency depend on the number of eligible beverage products you supply each year:

Annual volume of eligible beverage products Mandatory reporting frequency*
Up to 100,000 (Micro) Annually
100,001 to 300,000 (Small) Quarterly
More than 300,000 (Large) Monthly
* Beverage manufacturers can choose to report sales volumes more frequently than their minimum reporting requirement.

When are invoices due?

Payment is due within 25 business days.

The 25-business-day payment term has applied since the March 2026 invoice. It replaced the previous payment term of five business days.

Your invoice will show the amount payable and the relevant due date.

Understanding your invoice

Your invoice may include:

  • business or site details
  • the invoice number and date
  • your manufacturer site scheme ID
  • the relevant billing period
  • quantities for each material type
  • the unit price for each material type
  • the amount charged for each invoice item.

Invoice item descriptions

You may see the following descriptions on your invoice:

Scheme contribution

A charge based on the sales volumes your organisation reported for the period.

Adjusted scheme contribution

A correction made after an earlier invoice was calculated using an estimate and your organisation subsequently submitted its actual overdue sales volumes.

Scheme contribution estimate

An estimated charge for a period where sales volumes were not reported by the due date.

Audit adjustment

An adjustment that has been reviewed and approved for a particular material type and reporting period.

What if the volumes on my invoice look incorrect?

A difference may occur because:

  • a sales volume submission was missed and an estimate was used
  • an adjustment has been applied to the unit count.

Check the sales volumes recorded in the CDS Business Portal for the relevant period.

If you submitted incorrect volumes, enter the corrected volumes for that period through the portal. You may need to provide a reason, comments and supporting documents. The adjustment will be reviewed, and you will be notified of the outcome.

An approved adjustment may appear on a later invoice, depending on when it is approved in the billing cycle.

Can I calculate an invoice in advance?

You can estimate a scheme contribution by multiplying the applicable price for each material type by the corresponding eligible container volumes.

The final invoice may differ if reported volumes, scheme prices or approved adjustments change.
