Integrations for catering & event software

Yes. Univents turns your invoices into a DATEV posting batch your tax advisor can import directly. Accounts, tax keys and the period are set in your settings. It is a file export, not a permanent connection to DATEV.

Yes. You connect your Lexware Office account once by signing in at Lexware, and from then on every issued invoice transfers with one click — with line items, tax rates and the recipient as a contact. On request Lexware Office reports the payment status back. Small businesses under § 19 UStG can transfer their invoices too.

You can transfer directly to Lexware Office, sevdesk and bexio: issue the invoice, hand it over with one click, optionally create the customer contact along with it and have the payment status reported back. For a file handover there is the DATEV posting batch and the BMD CSV export. BuchhaltungsButler is listed in the directory as in preparation — the interest button there helps us set the order.

Yes, in both directions. Confirmed events appear in the connected calendar and changes to the date flow back into Univents. There is one shared workspace calendar plus a personal one per admin seat; staff subscribe to their shifts as a calendar feed instead.

Yes. Univents has a REST API with per-workspace keys, plus an MCP endpoint for AI assistants such as Claude. It lets your own systems read and write events, contacts, quotes and staffing.

Tell us. A lot can already be connected today through the REST API or a middleware service, and providers with visible demand move up the queue.

Yes, if you switch it on. For the direct connections Univents checks hourly whether a transferred invoice is marked as fully paid there and then marks it as paid on your side too. The switch is off by default — and you should not use it together with the bank statement import for the same invoices, or the same payment is counted twice.

With Lexware Office, yes: invoices without VAT are created there as a tax-exempt document under the small-business scheme. sevdesk and bexio do not support that tax case through the interface — there you create such invoices manually or hand them over via the DATEV/BMD export.
