What an AI employee can actually handle in Lexware

An AI employee doesn't just work through a list mechanically. It can carry out steps in a sensible sequence and reuse information from one step in the next. In Lexware, this is particularly useful for invoices, contacts, and articles.

Preparing and completing invoices faster

• The AI employee can create new invoices.
• It can create and finalize invoices directly.
• It can retrieve existing invoices.
• It can list invoices for a specific customer.

This saves time especially with recurring processes — particularly when the same information would otherwise need to be checked or transferred by hand again and again.

Managing contact data without duplicate entry

• The AI employee can create new contacts in Lexware.
• It can retrieve existing contacts.
• It can update contact data.
• It can pull up contact lists.

This helps when data comes in from emails, forms, or other systems and you don't want to maintain everything twice.

Keeping articles well maintained

• The AI employee can create new articles.
• It can retrieve individual articles.
• It can update article data.
• It can retrieve article lists.

This noticeably reduces work, especially with services, products, or prices that change regularly.

Why this pays off for SMEs

In many small and medium-sized businesses, administrative work ends up resting on just a few people. That's exactly where more time gets lost than you notice day to day: transferring data from emails, searching for contacts, preparing invoices, double-checking details. It adds up.

When you automate these kinds of tasks in Lexware with AI, less of it lands on your team. At the same time, you don't give up control — approvals can still go through people at the important points if that's what your process requires.

It's also worth being clear here: only functions that are actually included in the existing Lexware action list are described in this piece. The AI employee can create, retrieve, list, and in some cases update contacts, articles, and invoices in Lexware. Nothing beyond that is being promised here.

An example from everyday work

Imagine your virtual AI employee is named Mira. She handles recurring invoicing work that would otherwise sit with your team.

A new customer inquiry comes in by email. The message includes the company name, the contact person, and the services requested. Mira checks the details and first looks in Lexware to see whether the contact already exists — by retrieving existing contacts or checking the contact list.

If the contact doesn't exist yet, Mira creates it in Lexware. If it already exists, she checks whether details like the name or email address need updating. If something's out of date, she updates the contact.

Next, Mira looks for the matching articles or services. She retrieves individual articles or checks the article list. If an article is missing, she creates it. If an existing entry is outdated, she updates it.

In the next step, Mira creates the invoice in Lexware and carries over the relevant information from the contact and the article.

Things get interesting in the cases that don't run cleanly. If, say, an expected line item is missing or an article can't be clearly matched, Mira doesn't just guess. She hands the task back to a person and briefly explains what's missing or unclear.

A team member fills in the missing information or approves the selection. After that, Mira can continue. If everything is complete and unambiguous, she can create and finalize the invoice directly.

Bottom line: your team has to gather less information, enter less data twice, and field fewer follow-up questions. That's exactly why a workflow like this is often more useful in practice than it sounds at first.

How to get to automation without programming

There are two ways to set up a workflow like this.

The first is a ready-made virtual employee from the Scalan marketplace. In that case, the automation already exists and you don't need to configure anything yourself.

The second route goes through Scalan's guided assistant. There, you describe in your own words what should happen — for example: create a customer contact in Lexware, check the article, and prepare the invoice. That's how your own virtual employee gets built, without you having to write any code.

Why this often works better in practice than manual work or node-based tools

Manual work costs time — especially when information keeps getting transferred between systems. On top of that, the risk of errors rises every time data gets touched again.

Node-based automation tools can technically connect these processes. But in many SMEs, that still ends up resting on one person who builds the logic, maintains it, and reopens it whenever something breaks. It works, but in everyday use it's often more exhausting than it sounds at the start.

A virtual AI employee is easier for many teams to work with. You describe the goal, the employee works through the task, and it flags things when something isn't clear. That's exactly what makes the difference when automation in a business isn't just supposed to exist, but actually get used.

Especially with topics like workflow, AI agent, AI employee, and automation, what matters in the end isn't just the technical connection — it also has to stay understandable.

Trust, data protection, and implementation

For many companies, the framework matters just as much as the functionality. Scalan can support GDPR compliance and hosting in Germany. That's especially relevant when working with customer, contact, or invoice data.

For the Lexware actions named in this article, you don't need an additional developer, as long as the integration and the virtual employee are set up appropriately. If an individual special case goes beyond that, it needs to be reviewed separately. This article covers only the documented standard actions from the provided action list.
