Q : My client is not registered on Peppol. Can I still send him an invoice via this network?
A: No, both parties must be registered on the Peppol network for the invoice to be sent. If your client is not registered, you will have to send them the invoice by another means, such as email or PDF.
Q: What happens if I send the invoice and the recipient is not registered on Peppol?
A: You will not be able to send the invoice via Peppol. The option will not work, and you will receive an alert message about this.
Q : How can I find out if my client is registered with Peppol?
A : You can check whether your client is registered with Peppol by using our Peppol registry available online.
Simply enter your client's company number to see if they are registered.
Example :
If you're not sure, contact your client directly to confirm.
​
​Q: Do all invoices have to be sent via Peppol?
A: Since 2026, electronic invoicing via Peppol is mandatory for all invoices exchanged between Belgian professionals (B2B). This means that invoices between Belgian self-employed individuals and Belgian companies must be sent via Peppol. Invoices issued to private individuals (B2C) or to foreign customers are not subject to this obligation. For those clients, you can continue using other invoicing methods, depending on their preferences.
Q : Can I use Peppol for international transactions?
A: Yes, Peppol is designed to facilitate cross-border transactions within the European Union and even beyond. However, make sure that your client is also registered on the Peppol network so that the invoice is received correctly.
​
​Q: How can I be sure that my registration with Peppol is correct?
A: When registering, it is essential to provide accurate information, such as your company number and contact details. If you have any doubts or need assistance, you can contact our support team to check your registration.
​
Q : Does Peppol have an additional cost with Accountable?
A : There are no additional costs for using Peppol with Accountable.

Très bien, disponibilité !

C’est hyper clair et le service est impeccable, vous répondez vite. La seule chose que j’ai remarqué qui pourrait être une nouvelle fonctionnalité: avoir la possibilité d’être plus précis au niveau de la détermination de ce qu’on paye pour nos cotisations sociales quand on a choisi un plan d’apurement. Par exemple, 300€ par mois au lieu que le choix soit juste par trimestre.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful…my accountant and tax advisor are good, but never so comprehensive and accurate. Combined with the AI I never feel alone with Accountable

Le contact avec l'equipe ! On n'a pas affaire à un chat avec un robot stupide qui ne comprend rien mais avec des humains et un vrai dialogue

altijd snelle, vriendelijke en professionele service. Ook al heb ik door gebrek aan activiteit weinig gebruik kunnen maken van uw diensten. Gisteren heb ik het contract opgezegd, en ook dat is heel vlot verlopen. Waarvoor dank.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answer to most of the basic questions, specific scenarios need counsel from a human which your team performs beautifully.
