Event invoices that land in sevDesk

Every ticket purchase in Streavent already creates an invoice. Over the Open API those invoices, credit notes and billing contacts flow into sevDesk as vouchers and contacts, ready for the books.

The problem

The event is over, and accounting starts from a stack of PDFs

Tickets sold, invoices went out, refunds happened, and now someone re-enters every document into the accounting tool by hand. Numbers get transposed, the credit notes never match the invoices, and the tax advisor waits.

Event invoices into sevDesk

Every ticket purchase in Streavent creates an invoice. Over the Open API it lands in sevDesk as a booked voucher, so your accounting starts from real data, not a re-typed list.

Cancellations as credit notes

Cancel a ticket and Streavent issues a credit note. It flows to sevDesk against the original invoice, so refunds and books stay in sync without a manual correction.

Contact

Buyers as contacts

The billing contact behind each purchase reaches sevDesk as a contact record, new ones created, known ones matched, ready for invoicing and the DATEV export.

These are the most common flows, not all of them. Speakers, sponsors, agenda and more sync too, and you can create a whole event straight from your tool.

How it works

How Streavent connects to sevDesk

code

Over the Open API

Streavent's REST API (from the Growth plan) exposes invoices, credit notes and billing contacts.

sync

No-code via Zapier or Make

Prefer no dev work? A Zapier or Make flow picks up each new Streavent invoice and creates the matching voucher in sevDesk, with no script to maintain.

receipt_long

Ready for your tax advisor

Invoices, credit notes and vouchers land in sevDesk as booked documents. From there the DATEV export runs as usual, so your tax advisor works with the numbers.

For your team

One event signal for your whole team

account_balance

Finance: no invoices re-typed

Every ticket invoice and credit note reaches sevDesk on its own. Finance stops re-keying documents and starts the month from a set of books that already balances.

event_available

Event team: billing runs itself

You set ticket prices and tax rates once. Streavent invoices each purchase and hands it to sevDesk, without anyone exporting a list after the event.

support_agent

Tax advisor: clean books

Documents arrive in sevDesk in order, numbered and matched. The DATEV export runs from real data, so month-end closes without a round of questions.

FAQ

Frequently asked questions

Streavent is an all-in-one event software for professional B2B events with 200 to 5,000 attendees that connects to sevDesk over its Open API. Ticket invoices, credit notes and billing contacts flow to sevDesk as vouchers and contacts, ready for the DATEV export. Registration, ticketing, check-in, badge printing and event app run in one platform, hosted in Germany.

No, and we will not pretend otherwise. The connection runs over Streavent's Open API (REST, from the Growth plan) into the sevDesk REST API, or over no-code tools like Zapier and Make. That covers the flows that matter, invoice, credit note and contact into sevDesk, but you or a developer set the mapping up once. A built-in native sync exists today only for HubSpot, Salesforce and DATEV.

The billing documents from your event: the automatic invoice per ticket purchase, the credit note on each cancellation, and the billing contact behind them. Streavent creates these anyway, the integration hands them to sevDesk as vouchers and contacts so they are booked, numbered and ready for the DATEV export.

No. Streavent is the event layer in front of your accounting: sevDesk stays the system of record for your books, the DATEV export and your tax advisor, Streavent issues the event invoices and hands them over. Details on the pricing page.
