Do we have to replace Lexware?

No. Lexware Office stays your program for invoices and bookkeeping. We just make sure the data gets there on its own instead of being typed in.

Does this work with lexoffice?

Yes, lexoffice is now called Lexware Office. For older Lexware programs installed on your own computer, we check in the intro call what is possible.

Does the system send invoices without me?

Only if you want it to. Usually we create invoices as drafts, and you check and send them. What may run on its own, you decide in the blueprint.

What changes for my tax adviser?

Nothing. The documents are created in Lexware Office as before, just without the typing.

Connect Lexware and stop retyping invoices

The job is done, and the invoice is already waiting in Lexware Office. We connect your website and your system to Lexware so customers, quotes and invoices are entered only once.

Sound familiar?

“In the evening I'm still in the office writing invoices.” Yet the data is already there: in the enquiry, in the job, on the timesheet. Still someone types address, line items and amounts into Lexware again, and every retyping is a chance for a transposed digit.

Invoice straight from the job

The job has been finished for days, but the invoice waits until there is time for paperwork at the weekend.

Once the job is done, the system creates the invoice in Lexware Office, with customer, line items and hours. You check it and send it.

Customers kept in two places

The customer has moved. Lexware has the new address, the job book still has the old one.

Customers are kept in sync between your system and Lexware Office. Change an address in one place, and it is right in the other too.

Who has paid already?

Before the next appointment goes out, someone opens Lexware to check whether the last invoice was paid.

The payment status from Lexware Office shows right next to the job, and in the customer portal if you like. You see unpaid invoices without searching.

Before a project starts, there is a fixed price.

No open-ended invoice, no surprise at the end: you know what it costs before we begin. The blueprint has a fixed price too and is fully credited when you place the order.

At a glance

What happens by itself between your system and Lexware Office.

How it works

01Look at what is thereWe look at how quotes and invoices are created today and which data lives where. The blueprint sets out what will run on its own and what you keep checking yourself, with a fixed price.
02ConnectWe connect your website or your system to Lexware Office through its official interface. Your bookkeeping stays where it is.
03Runs on its ownFrom then on customers, quotes and invoices move by themselves. We host the connection, keep an eye on it and adjust it when Lexware changes something.

What this could look like for you

A made-up example, not a customer project – it shows how a project like this typically runs with us.

Starting point

A painting business writes its quotes in Lexware Office but plans its jobs in a spreadsheet. When a job is finished, the owner copies address, areas and hours into the invoice by hand in the evening.

Solution

We build a lean job management system and connect Lexware Office: a quote becomes a job with one click, and once the job is done, the invoice is waiting as a draft in Lexware. The payment status flows back into the job list.

Result

The invoice is one click to check instead of an evening of typing, transposed digits are gone, and the owner sees unpaid invoices without opening two programs.
