FAQ #

What do I need to use the integration?

You need a timeBuzzer Pro account and a Lexware Office account with a plan that supports partner integrations.

Which layers can I import to?

You can import both customers and services into any layer. This allows you to tailor the integration perfectly to your individual structure.

How does automatic import work?

You can activate automatic import to automatically transfer future customers or services in Lexware Office to a selected layer in timeBuzzer.

If you want to import existing customers and services, you can do so using the manual import function.

I only record projects – can I still bill Lexware Office customers?

Yes, that works. Import and export are independent of each other. Even if you don’t create any customers in timeBuzzer, the export will always show you all Lexware Office customers. This means you can still bill your recorded project times for each Lexware customer.

Only users with the Administrator role can create Lexware Office invoices or import Lexware Office customers and services in timeBuzzer. Managers and regular users do not have access to these functions.

Which articles are imported?

All articles in Lexware Office that are marked as service are available for import into timeBuzzer. Currently, only the names are transferred; hourly rates cannot be imported at this time.
