Your benefits with easybill
From sentence to invoice
Describe informally what you need. The assistant turns it into a draft invoice with the relevant line items, which you then only need to approve.
Draft first, your “Yes” decides
The assistant always creates a draft first. It is not finalized until you approve it; only then does easybill assign the invoice number, and the document is unchangeable.
E-invoicing included
If you want, invoices are created directly as XRechnung or ZUGFeRD.
German tax reality
Small business scheme (Kleinunternehmerregelung), Reverse Charge, intra-Community supply (innergemeinschaftliche Lieferung): the tax options are available to the assistant and are shown correctly.
From quote to payment in the dialogue
Convert a quote into an invoice, send it, record payment, and, if needed, trigger a payment reminder or dunning notice. You handle the entire chain in chat.
Your data stays in your account
The assistant works via the official API in your own account: same login, same permissions, no data export to third parties.
Have documents created from an informal description
Invoice, quote, order, credit note: you chat with your AI assistant, and it turns it into a ready-to-use draft in easybill.
- Customer and payment terms come from your existing data
- Also possible from external sources, e.g., “turn this email into a quote”
- Line items, quantities, and amounts appear immediately in the draft
From quote to paid invoice, everything in chat
Quote accepted? “Turn it into an invoice.” Line items and terms are carried over automatically.
- Finalize and send the invoice—one sentence is enough
- Trigger a payment reminder or dunning notice if a document remains unpaid
- The entire chain from quote to payment stays in the dialogue
Information and payments from real account data
You write to your AI assistant: “RE-1042 has been paid.” The payment is assigned to the invoice, and your open items are correct again.
- Who still hasn’t paid?
- Which quotes are still open?
- Revenue with customer X this year?
Master data and times under control
Create or edit customers and items, find duplicates: the assistant keeps your records clean.
- Create new customers and items on the fly
- Track down duplicate entries
- For freelancers and agencies: you write “Invoice all open hours from project X,” and recorded times become a draft invoice
- Create and delete projects, assign documents to the project directly or later on
Send via email or by mail
Finished documents are sent by email or as a letter via easybill postal delivery, optionally as registered mail.
- Email sending directly from the chat
- Physical letter for recipients without a digital invoicing channel
- One sentence in the chat, one stamped letter with your customer
