You purchase credits for your TRONVoice account. Each time you send an invoice or a quote to a client, one credit (worth €0.65) is consumed. There is a strict monthly cap of €16.25, which equals 25 documents. If you send more than 25 invoices or quotes in a month, you will not be charged extra; those additional documents are essentially free. Any unused credits remain in your account forever.
What payment methods can my clients use?
TRONVoice integrates with popular online payment gateways, allowing your clients to pay invoices directly and securely with a click. Supported methods typically include iDEAL, credit/debit cards, and Bancontact. This convenience leads to significantly faster payments and less administrative hassle for both you and your clients.
Can I manage more than one business?
Yes, TRONVoice supports multiple administrations. You start with two administrative profiles for free, allowing you to manage the invoicing for two separate businesses or clients from one account. If you need more, additional administrations can be added for a fixed monthly fee, which is ideal for accountants or entrepreneurs with multiple ventures.
What happens if I stop using TRONVoice for a while?
Your data and any remaining credits are safe. One of the core principles of TRONVoice is that your purchased credits never expire.
