Frequently Asked Questions

What is BillingEngine?
BillingEngine is an accounting software that allows small businesses in particular to create and manage invoices quickly and easily.
Are my invoices machine-readable e-invoices?
Yes, all invoices you create with BillingEngine comply with the XRechnung and ZUGFeRD standards according to EN 16931 and can be electronically read by the recipient.
Do my invoice numbers have to start with 1?
No, you can also start with any higher invoice number within the year. All subsequent invoice numbers will then be automatically incremented.
How secure are my data?
The security of your data is our top priority. All data is always transmitted encrypted and stored exclusively on German servers. To protect against data loss, we perform regular backups. As a registered user, you can obtain additional protection through a Data Processing Agreement with us. Our detailed Technical and Organizational Measures precisely define how we ensure the protection of your personal data.
Who can view my data?
Only you and the people you grant access to (e.g. your tax advisor or your employees) can view your data. We never pass on your data to third parties. However, you can grant our support team access to your data at any time (temporarily) by enabling the Support Access option in your settings.
How are my data encrypted?
All data that you send to BillingEngine or receive from there via your browser is always encrypted with SSL. In your browser, you will therefore always see a small padlock symbol next to our web address.
Where is the server of BillingEngine located?
Our server is located at DigitalOcean in Frankfurt (Germany) and meets all requirements of the GDPR. We have concluded a Data Processing Agreement with DigitalOcean.
Can I use BillingEngine for free?
Yes, BillingEngine is basically free if you do not create more than 3 invoices per month. If you want to create more invoices, you can switch to one of the paid plans at any time.
What added value do the paid plans offer?
In the paid plans, you can create more invoices per month (depending on the plan you choose). In addition, the watermark on the PDFs is removed and you can use additional features such as recurring invoices and reminders. You can also set up additional access for employees or your tax advisor.
Can I switch to a different plan?
Yes. You can switch to a higher or lower plan at any time free of charge.
Will I receive a tax-deductible invoice?
Yes, every customer automatically receives a tax-deductible invoice with value-added tax from us for each payment, which you can claim as a business expense. You can also download all your invoices at any time in your account.
