# Are All Available Apps and Integrations Available for Free? The activation of all apps and integrations in BestInvoicing is free. However, behind the connection, outside the BestInvoicing environment, there may be a paid service. Examples are: * Connection with **Ponto**: you will need a Ponto subscription, which may incur a monthly fee. * Transmission via **PEPPOL**: included in your BestInvoicing subscription, you can send up to 100 documents over this network. Above 100 documents the send price is $ 0.10/document. * Online payment via **Mollie.com**: you will need a Mollie.com subscription. They have different formulas and pricing for transaction fees. * Connection with **MailChimp**: this program offers free or paid subscription formulas, depending on what you want to set up in terms of email campaigns. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
