Frequently Asked Questions

TRONVoice FAQ

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

You purchase credits, and each invoice or quote you send costs €0.65, deducting one credit. The key benefit is the monthly cap: you will never be charged more than €16.25 (25 credits) in a single month, regardless of how many documents you send beyond that. Purchased credits never expire, so you only pay for what you use, when you use it.

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

Every feature in TRONVoice is available to all users from the start. This includes unlimited invoicing, the CRM with notes and tasks, automatic subscription billing, online payments (iDEAL, credit card, Bancontact), payment reminders, custom branding, cloud storage integration, and your own administrative email inbox. There are no premium tiers or upsells.

Are there any monthly subscription fees?

No, there are no mandatory monthly subscription fees. You operate on a pure pay-per-use credit system. The only recurring cost is if you choose to add extra client administrations beyond the first two (which are free), which is a fixed €2.50 per month per additional administration.

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

If you don't send any invoices or quotes in a given month, you pay nothing at all for that period. Your existing credits simply remain in your account, ready for when you need them, as they have no expiration date. This makes TRONVoice exceptionally cost-effective for businesses with fluctuating workloads.
