Invoicing and payment

Invoicing of fees and payment deadlines 2025-2026

First invoice: the 2025 statement*

In April 2026, Valumat will send members a statement for the previous year (2025). This statement corresponds to the difference between the actual membership fee for 2025 (see 2025 declaration) and the instalments already invoiced and paid for the same year. The invoice resulting from this statement is payable within 30 days.

Three advance invoices for 2026:

Valumat will send members three advance invoices for 2026 simultaneously. The total amount of this advance on financing is calculated as follows: number of mattresses put on the market in Belgium in 2025 x 2026 rates.

1. The first invoice, corresponding to 25 % of the total amount, is due on 31 May 2026.
2. The second invoice, also corresponding to 25 % of the total amount, must be paid on 31 August 2026.
3. The third invoice, representing 25 % of the total amount, will fall due on 30 November 2026.

In practice, this means that only 75 % of the advance on financing for 2026 will be due in 2026. The remaining balance of 25 % will be invoiced in April 2027, at the same time as the final statement for 2025. The 2026 statement corresponds to the difference between the actual membership fee for 2026 and the instalments already invoiced and paid for this period.

This invoicing method is designed to reduce pre-financing for members, while allowing immediate recovery of the VAT charged.
