25It follows that, similarly to the entitlement to interest for late payment provided for in Article 3(1) of Directive 2011/7, the entitlement to a fixed minimum sum provided for in Article 6(1) of that directive, which also arises from a ‘late payment’ within the meaning of Article 2(4) of that directive, is linked to individual ‘commercial transactions’. That interest, like that fixed sum, is to become payable automatically upon expiry of the period for payment laid down in Article 3(3) to (5) of that directive, provided that the conditions set out in paragraph 1 thereof are satisfied (see, to that effect, judgment of 1 December 2022, DOMUS-SOFTWARE, C‑370/21, EU:C:2022:947, paragraph 23 and the case-law cited).
