TRONVoice FAQ

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

You purchase credits, and each invoice or quote you send costs €0.65 in credits. The key benefit is your monthly spending is capped at €16.25. This means once you've sent enough documents to reach that cost (about 25 invoices), all further invoices you send that month are essentially free. Your purchased credits never expire, so you only top up when needed.

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

Every feature is available to all users from the start. This includes unlimited invoices, the CRM with notes & tasks, automated subscriptions and payment reminders, online payments (iDEAL, credit card, Bancontact), custom branding with your logo, and 2 free client administrations. There are no tiered plans or upsells for core features.

What happens if I need to manage more than 2 client administrations?

You start with 2 administrative profiles (e.g., for your own business and perhaps one client) for free. If you are an accountant or bookkeeper who needs more, you can add extra administrations for a fixed fee of €2.50 per month, each. This allows you to manage invoicing for numerous separate clients from one dashboard.

How do I get started and what is the free credit?

Getting started is completely free. Simply sign up and you will immediately receive €2.50 in free credits to use on sending your first invoices. There are no monthly fees, and you only pay for what you use beyond the free credit. You can explore all features and start invoicing right away without entering any payment details.
