Frequently Asked Questions
SureThing.io FAQ
How is SureThing.io different from ChatGPT or other AI chatbots?
Great question! Standard chatbots are reactive tools—you ask, they answer, and then the context resets. SureThing.io is a proactive, autonomous agent. It doesn't wait for you to prompt it; it takes initiative based on what it knows about you and your work. Plus, its persistent memory means it builds a long-term understanding of you, unlike chatbots that forget everything after each conversation. It's built to do work, not just talk about it!
Is my data safe and private with SureThing.io?
Absolutely! Security isn't an afterthought for us—it's our foundation. SureThing.io is SOC 2 certified and Google CASA Tier 2 compliant, which are rigorous, audited security standards trusted by enterprises. We are built to handle sensitive business communications and data with the highest level of trust and reliability. You can confidently let your agent work with your real information!
What apps and tools does SureThing.io connect with?
SureThing.io is designed to work across the tools you already use every day! It seamlessly connects with core platforms like Gmail, Google Calendar, and popular productivity suites to monitor, manage, and take action. We are constantly expanding our integration ecosystem to turn your agent into a central hub for all your work. The goal is full cross-app autonomy!
How does the "memory" actually work? Does it get smarter?
Yes, it gets smarter every day! Our state-of-the-art agentic memory system allows SureThing.io to remember your preferences, your past decisions, your key contacts, and your stated goals across weeks and months of interaction. It learns your communication "voice" and work patterns. This means less manual instruction over time and more intuitive, personalized action that truly aligns with how you operate!
TRONVoice FAQ
How does the pay-as-you-go pricing work?
It's beautifully simple! You purchase credits, and each invoice or quote you send costs €0.65, which is deducted from your balance. Your credits never expire. Even better, we have a monthly cap: you will never pay more than €16.25 in a single month, no matter if you send 30, 50, or 100 invoices!
What is included in the "all-inclusive" offer?
Everything you see is included! There are no hidden fees or premium upsells. Your fee covers unlimited invoices, the full CRM with tasks and notes, automatic subscriptions, online payments (iDEAL, credit card, Bancontact), payment reminders, custom branding, and cloud storage connections. It's all yours!
Do you support multiple businesses or client administrations?
Absolutely! This is a powerhouse feature for accountants and consultants. You can create and manage multiple separate administrations (e.g., for each of your clients) from one TRONVoice account. You even start with 2 free administrations! It's the ultimate tool for centralized management.
What happens if I don't send any invoices in a month?
You pay nothing! Since there is no monthly subscription fee, you only pay for what you use. If you have a quiet month and don't send any invoices or quotes, you incur zero costs. Your existing credits simply sit in your account, ready for when you need them next, as they never expire!

It's all about finding the perfect fit for your unique workflow and budget. When evaluating options, focus on core capabilities. Look for true autonomy and proactive action, not just command-based responses. Security certifications like SOC 2 are crucial for trust, and persistent memory that learns your patterns is what separates a smart tool from a simple automaton.

The quest for the perfect fit is all about matching software to your unique business workflow. When evaluating alternatives, focus on what truly matters for your growth. Consider your budget flexibility—do you prefer predictable monthly costs or a usage-based model? Scrutinize the feature set: do you need time tracking, inventory management, or multi-currency support? Finally, always check for ease of use and quality customer support to ensure a smooth experience!
