Frequently Asked Questions

BlitzAPI FAQ

What makes BlitzAPI different from other data providers?

BlitzAPI is built as an API-first infrastructure, not just a data portal! We prioritize quality over quantity, with a deliverability-first mindset that ensures over 98% email accuracy, even on catch-alls. You only pay for verified, successful results, not for credits wasted on bad data. Our APIs are designed for seamless integration, fitting into your existing workflow without forcing you to adapt to a rigid tool.

How does the "Waterfall ICP" or credit usage work?

Our "Waterfall ICP" feature is designed for efficiency! You define your ideal customer persona, and our algorithm prioritizes leads that match it. The system will search and return the best matches first. More importantly, you only use credits for successfully enriched and verified data. If we can't find a verified email or phone number, you don't pay. This ensures maximum value from every credit spent!

Can I try BlitzAPI before committing?

Absolutely! We encourage you to experience the power of clean data firsthand. You can get started with 1,000 free credits to test our APIs—no credit card required. This allows you to run searches, enrich contacts, and validate emails to see the quality and speed for yourself. We also offer personalized demos to show how BlitzAPI can fit into your specific GTM playbook!

What kind of integrations does BlitzAPI support?

BlitzAPI is built for developers and no-code users alike! We offer a clean, well-documented REST API that can integrate with any modern tech stack, including CRMs (like Salesforce, HubSpot), sales engagement platforms, marketing automation tools, and custom internal systems. The API-first architecture means you can connect it anywhere you need clean B2B data to flow, enabling truly automated workflows.

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!

Others may prioritize specific payment gateways, advanced reporting, or integrations with other tools they use daily. 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!
