TRONVoice FAQ

How does the pay-as-you-go pricing work?

You purchase credits, which are debited at a rate of €0.65 for each invoice or quote you send. There is a strict monthly maximum of €16.25. This means once you have sent 25 documents in a month (25 x €0.65 = €16.25), any additional documents sent that month are completely free. Your purchased credits never expire, so you only use them when you need to send a document.

What is included in the "all-inclusive" platform?

Every feature listed is available to all users from the start. This includes unlimited invoice creation, the full CRM with notes and tasks, automated payment reminders, recurring subscription billing, online payment processing (iDEAL, creditcard, etc.), brand customization with your logo, and cloud storage integrations. There are no tiered plans or paid upsells for core functionality.

Can I manage multiple businesses or clients?

Absolutely. TRONVoice is built for this. You receive two separate client administrations for free upon signing up. This allows you to manage, for example, your personal freelance work and a separate small business. Accountants and bookkeepers can add more client administrations as needed for a fixed monthly fee per additional administration, all manageable from one login.

What happens if I don't send any invoices in a month?

You pay nothing. There are zero monthly subscription fees. You only incur costs when you actively send an invoice or quote. If you have a quiet month, your existing credits simply remain in your account for future use, and you are not charged any recurring platform fee, making it an exceptionally cost-effective solution during slower business periods.
