FAQs - Frequently asked questions:

Invoicing software

  • Can I use the 1&1 invoicing software to create professional invoices online?

    Yes. With the online billing software from 1&1, creating invoices is a walk in the park. In just a few clicks, your invoice is complete. The intuitive interface allows you to create invoices quicker than by hand, and with fewer errors—if any required information is missing, such as the tax code, the program will let you know. You only need to enter the data once; from then on, the invoicing software will fill out the required information automatically. For example, customer addresses only need to be entered once as master data, which is then stored and used for recurring invoices. This way, you don't need to repeat the entry process every time, allowing you to save time and energy for your core business instead.

    If you want to turn prospects into customers, you need a professional and compelling offer—which you can create just as quickly and easily with the online invoicing software. Don't let the next customer pass you by; convince them with your offer.

    You can use the software to create professional invoices from anywhere—whether you're at home, at work or on the move. You can also access your personal account from any device; with the invoicing software, bookkeeping is totally flexible and location-independent.

    What's more, the billing software from 1&1 powered by sevDesk always generates consecutive invoice numbers—meaning one less thing to think about. When it comes to identifying invoices, sequential invoice numbers are a must. Errors can easily occur when generating these by hand, and not without consequence. With the online invoicing software from 1&1, you can be sure to avoid careless mistakes with regards to invoice numbers.

    Small businesses and freelancers also need to promote themselves: communicate your name or your brand continuously to make sure that your customers recognise it. Professionally designed invoices are an opportunity to advertise. With the 1&1 invoicing software, you can design your invoices yourself: the letterhead, logo and layout can all be customised according to your taste. No specific design skills are required—thanks to the intuitive interface, you can handle the process quickly and easily.
  • What are the advantages of the online invoicing software for small businesses and freelancers?

    There are many advantages to using the 1&1 invoicing software online, such as the integrated post interface. This enables you to send your finished invoices directly by post without having to print them, put them in an envelope and post them yourself. If you want to send your invoices by email, the invoicing software helps you to complete your email automatically with the invoice as a PDF attachment. Simply click send and your invoice is on its way. Of course, you can also download the PDF file to send the invoice yourself or keep a copy for your records.

    If you want to export important files, the online billing software from 1&1 enables you to send your files in either CSV, PDF or ZIP format.
  • Can I use the invoicing software to cancel invoices?

    The accounting program not only makes it easy to create invoices, you can just as easily cancel them too. With the invoicing software, you can cancel and rectify any incorrect invoices in just a few clicks. Then, all you need to do is send the relevant cancellation invoice to the customer. Thanks to the software's simple and intuitive usability, you save considerable time and stress.
  • Can the online invoicing software be used on different devices?

    With the 1&1 accounting program powered by sevDesk, you benefit from total flexibility—regardless of whether you need the invoicing software for Mac or Windows. The software is also available as an app for iOS and Android, allowing you to create invoices on your smartphone or tablet.
