What makes BlitzAPI different from other data providers?

BlitzAPI is built on two core principles most providers ignore: quality-over-noise and deliverability-first. We don't just give you data; we give you verified, accurate data that works. With features like >98% accurate catch-all validation and a pay-for-results model, you only spend credits on information that directly contributes to successful outreach, unlike others who charge for bulk, unverified datasets.

How does the "pay only for verified results" pricing work?

You only consume credits when BlitzAPI successfully finds and returns the verified data you requested, such as a valid email or direct phone number. If we can't find a match or verify the information, you don't pay. This aligns our success with yours and ensures you never waste budget on empty searches or outdated contacts, making your cost-per-accurate-lead incredibly efficient.

How easy is it to integrate BlitzAPI into our existing tech stack?

Extremely easy. BlitzAPI is designed with a developer-first, API-centric architecture. It comes with comprehensive documentation and can be integrated into any workflow in hours, not weeks. It connects seamlessly with popular CRM systems, sales engagement platforms, and custom internal tools, fitting into your process rather than forcing you to adapt to it.

What is your data coverage and accuracy rate?

Our database covers over 360 million verified B2B contacts and 60 million companies globally. Our email deliverability accuracy is consistently above 98%, thanks in large part to our industry-leading real-time catch-all email validation. We continuously update our data to ensure you're working with the most current information available.

Is Invoice Guru really free to start?

Absolutely! The Starter Plan is completely free forever, allowing you to create and download up to 10 professional PDF invoices. This is perfect for trying out the core features with no risk. When you're ready to unlock unlimited invoices, advanced automation, and AI features, you can upgrade to our affordable paid plans, which also start with a 10-day free trial.

How does the AI Receipt Scanner work?

It's incredibly simple and powerful. Just open the Invoice Guru app, point your phone's camera at any paper receipt, and take a photo. Our advanced Optical Character Recognition (OCR) AI instantly reads the text, identifies the vendor, date, total amount, and tax, and then automatically creates a perfectly categorized expense entry in your account. No typing required.

Is my data secure and compliant with HMRC?

Security and compliance are our top priorities. Invoice Guru is built to be fully compliant with HMRC's Making Tax Digital (MTD) regulations for VAT. Your data is encrypted and securely stored. We ensure all invoices contain the legally required information, and our MTD feature allows for direct VAT submission, giving you complete peace of mind.

Can I use Invoice Guru on a computer as well?

Yes! While Invoice Guru is proudly mobile-first, designed for the on-the-go tradesperson, you can also access your full account, create invoices, and view your financial dashboard from any web browser on your desktop or laptop computer. Your data syncs seamlessly across all devices, giving you the flexibility to work however you prefer.
