Feature Comparison

TRONVoice

Pay-As-You-Go Pricing with a Hard Cap

TRONVoice dismantles the traditional subscription model. You pay a flat €0.65 only for each invoice or quote you actually send. Crucially, your costs are capped at €16.25 per month, meaning once you send 25 documents, every additional invoice that month is essentially free. Credits never expire, offering unparalleled financial predictability and fairness, especially for businesses with fluctuating monthly workloads.

Unified Client CRM & Task Management

The platform centralizes all client interactions by integrating a robust CRM system. You can store detailed client notes, attach relevant files, and create specific tasks linked directly to a client, invoice, or project. This eliminates switching between disparate apps, ensuring all communication, deadlines, and follow-ups are organized in one accessible location for you and your team.

Automated Online Payments & Subscriptions

TRONVoice accelerates cash flow by enabling clients to pay invoices instantly via popular methods like iDEAL, credit card, and Bancontact. Furthermore, it automates recurring billing for subscription-based services. Set up the billing cycle once, and the system automatically generates and sends invoices, handles payment reminders, and manages the entire renewal process seamlessly.

Multi-Administration Management

Designed for accountants, bookkeepers, and agencies, this feature allows you to manage completely separate client administrations from a single TRONVoice login. Each administration maintains its own isolated set of invoices, clients, and data. This powerful functionality streamlines workflow for professionals serving multiple clients, effectively replacing cumbersome Excel and Word document chaos.

Frequently Asked Questions

TRONVoice FAQ

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

You purchase credits within TRONVoice. Each invoice or quote you send costs €0.65, which is deducted from your credit balance. The key benefit is the monthly cap: you will never be charged more than €16.25 in a single month, regardless of how many documents you send after reaching that threshold (approx. 25 documents). Unused credits roll over indefinitely and never expire.

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

All core features of TRONVoice are available to every user without tiered plans or upsells. This includes unlimited invoice creation, professional templates, client CRM, task management, automated payment reminders, online payments (iDEAL, credit card, Bancontact), cloud storage connections, and the ability to manage two separate client administrations for free. You only pay the per-document fee when you hit "send."

Can I manage multiple businesses or client sets?

Yes, absolutely. TRONVoice includes two free "administrations," which are fully separate workspaces for different businesses or client groups. This is ideal for freelancers with a side business or accountants managing client books. You can easily switch between them with one login. Additional administrations can be added for a fixed monthly fee.

How do online payments work for my clients?

When you send an invoice via TRONVoice, you can enable online payment. The invoice email will contain a secure "Pay Now" button for your client.

The payment is processed securely, and both you and your client receive instant confirmation, speeding up your cash flow significantly.
