B2B e-invoicing in Montenegro
Businesses are not mandated to issue electronic invoices to other companies in Montenegro. There are plans for mandatory B2B e-invoicing; however, there is currently no regulatory obligation to implement it.
That said, businesses can voluntarily opt to issue e-invoices to other organisations—but only if they have obtained the buyer’s explicit consent to do so. If businesses choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by using, for example, an electronic signature.
Electronic fiscalisation is mandated for all businesses in Montenegro, requiring businesses to automatically report invoice data to the nation’s tax administration through certified software. However, there is no indication of when electronic invoicing will also become a requirement.
