Feature
Hungarian invoicing and receipt integrations with less manual administration
AI Booking was built for Hungarian service providers and includes native Billingo and Számlázz.hu integrations. Booking, payment, invoicing and the configured receipt flow can be managed in one system. Payment requests and bank transfers are supported, while email notifications can be controlled by document type.
What does this mean in practice?
Imagine an ordinary day with AI Booking working in the background. Before you even arrive at your business, the first booking is already in: a returning guest chose a time on their phone at 7:42 and received an automatic confirmation email. Your calendar is up to date; over breakfast, a glance at your phone shows what the day holds. The Hungarian invoicing and receipt integrations are designed to give you this peace of mind with less manual administration: native Billingo integration through its API, native Számlázz.hu integration as an alternative, and online invoices and computer-generated receipts — without spending the whole day by the phone.
While you're working, guests don't interrupt you with urgent calls, because your online booking page is available 24/7. In the afternoon, when you check back in, you review the incoming bookings, cancellations, and payments in a few minutes — and importantly, everything is organized, searchable, and exportable. The guest registry remembers what each person liked last time, so at their next booking you already know exactly what to prepare. Weekly statistics show you the trends: is revenue growing, how many new guests arrived, and which service is most in demand.
In the evening, when you close up the workshop or salon, you no longer need to keep a paper diary or send follow-up emails. AI Booking automatically sends tomorrow's reminders (and, in the Basic/Pro plan, the SMS messages), updates Google Calendar, and prepares the monthly statistics. Your job remains the professional part — the system takes over the booking administration.

How to use it in 3 steps?
- 1
Registration and basic settings
The first step is registration without a bank card (the Pro plan is free until December 31, 2026) — all you need is an email address or a Google account sign-in. The onboarding wizard walks you through your account basics (business name, contact, booking URL), then you set up your services: name, duration, price, description. Can be activated: Native Billingo integration — API-level connection. Your booking page is then already live, and your guests can book right away — with an average setup time of 15-30 minutes.

Working hours, calendar and notifications
In the second step, you set your working hours (weekly, daily, exceptions, time off), and connect your Google Calendar account so your private events also block booking slots. You decide which email templates are active (confirmation, reminder, follow-up) and when they go out (e.g. 24 hours before). In the Basic and Pro plans, you can also add SMS reminders. Can be enabled: Native Számlázz.hu integration — an alternative option. This way your guests receive an automatic, branded confirmation.

Sharing the link and daily use
The third step is sharing your booking link: in your Instagram bio, a Facebook post, a business card QR code, an embedded booking form on your website or a WordPress shortcode. From then on, the system works automatically with online invoices and computer-generated receipts. Each morning, you can check your mobile admin dashboard (installable from your phone's browser), view and accept the day's bookings, and export invoices to Billingo or Számlázz.hu at the end of the month. The statistics module shows how your business is growing.
+30-40%
more returning guests after the first 3 months — the combined effect of booking automation, reminders, and guest records. A typical result for providers; the exact figure depends on the industry and activity level.
How does it fit with the other features?
Why is it worth choosing Billingo or Számlázz.hu?
Both are established Hungarian document providers with online invoicing connectivity. AI Booking offers a native integration for each — choose the one used by your business and accountant.
How does it integrate with the booking process?
After successful payment, AI Booking initiates the configured document in the selected system. Required customer, service, amount and VAT data are transferred from a verified snapshot. Email notification is configurable and the process status remains visible in AI Booking.
VAT rates and special cases
Set the VAT code according to the provider's own tax status; there is no hard-coded default for everyone. Always consult an accountant or tax adviser for special or cross-border transactions.
Proforma invoice + bank transfer
If the guest doesn't pay online (e.g. pays via company bank transfer), the system automatically generates a proforma invoice, which the guest receives by email. Once the transfer arrives, you confirm the final invoice together with your accountant in the AI Booking admin. Useful for B2B bookings.
Refunds and cancellations
If you refund the guest's payment, the cancellation invoice is also generated automatically. The online invoicing system automatically reports the cancellation to the NAV (Hungarian tax authority). You only initiate the refund in the AI Booking admin — the rest is automatic.
Frequently asked questions
Do I need a separate Billingo or Számlázz.hu subscription?
Yes, you need a separate subscription to your own plan with the invoicing provider. AI Booking only provides the API integration. Both Billingo and Számlázz.hu offer a free or low-cost starter plan.
Is invoicing automatic?
When automatic issuing and notification are enabled, the system queues the document after a successfully settled payment. The external provider's response time may vary; status is visible in the admin interface.
What if the guest's billing details are incorrect?
Required billing details must be complete before issuing an invoice. An issued tax document cannot be edited; an incorrect document may need to be cancelled and replaced according to the billing provider's rules.
Can I use it as a flat-rate or simplified taxpayer too?
Yes, both Billingo and Számlázz.hu handle Hungarian tax forms. For tax questions, it's always advisable to consult an accountant — the system automates the operational side.
Can multiple companies or multiple tax numbers be managed?
Yes, if you run several businesses, a separate AI Booking account is recommended for each — every account can have its own Billingo/Számlázz.hu connection. In the Pro package, a separate invoicing profile can also be configured per staff member.
What about foreign guests?
For foreign or intra-EU transactions, VAT treatment depends on the transaction and partner data. AI Booking passes the recorded data to the billing provider, but the tax classification must be determined with your accountant.
How is data reported to the Hungarian Tax Authority?
AI Booking initiates the document in the selected Billingo or Számlázz.hu account. The Hungarian Tax Authority connection, eligibility and current reporting requirements must also be configured correctly in the document provider account.
