Plain invoicing program
- The invoice is typed by hand
- Hours are transferred via Excel
- Dunning happens sporadically
- The margin is only known after the fact
Create professional invoices in minutes: automated, legally sound and neatly tied into your business processes.
All data comes straight from CRM, projects and time tracking, with no manual steps and no external interfaces. From the quote to the paid invoice, everything stays in one system.
Definition
Invoicing software creates, sends, archives and manages quotes, orders, invoices and dunning notices digitally. Unlike a plain invoicing program, integrated invoicing software is cloud-based, multi-user and connected to sales, projects, time tracking and accounting. Anyone writing orders and invoices with it manages the open items, the recurring documents and the dunning stages in the same place. In teamspace the invoice therefore grows out of the order and the approved hours, not out of a second spreadsheet.
Billing hub
Booked hours, flat rates and travel expenses collect on the order. As soon as the condition is met, it switches the line item to due, without anyone piecing the invoice together by hand.

From quote to payment
Five steps from the billing module. Every document grows out of the previous one; address, line items and layout travel with it, so nobody enters anything twice.
A quote is built from the product catalogue, with price list, options and discounts. The status stays visible, and the Next Steps module is a reminder to follow up as long as there is no answer.
One click turns the accepted quote into the order, and the line items come along. The order is also the billing hub: it holds the payment plan, the billing rules and the status of every line item.
The order line items become work packages in the project. Hours are booked in the browser or in the web app, while flat rates and travel expenses come across from the project.
The order shows the billable line items and the invoice is created with one click. Depending on the setting, as a PDF, as ZUGFeRD or as XRechnung. Recurring invoices run on the schedule you set.
Open items sort themselves by status, and colour dots show the payment state. Dunning stages go out with their deadline and wording, either after approval or automatically.
Billing types
Time and materials, fixed price or duration: the type decides how a line item bills. One order mixes them in a single document.

Where it fits
Level of automation
You do not have to automate the invoicing software fully on day one. You begin with the manual route and raise the level of automation exactly when your processes are ready, in the same system and with no move to a different program.
Stage 1 · Manual
The order shows the billable line items, you review them and trigger the invoice with one click. As lean as a plain invoicing program, only without retyping from a second spreadsheet.
Stage 2 · Rules and templates
Assignment rules place approved hours on the right line item, recurring invoices run on the schedule you booked, and dunning works through its stages on its own once approved.
Stage 3 · End to end
The order turns into an e-invoice as ZUGFeRD or XRechnung, incoming documents are recognised by their barcode symbol, and the DATEV booking data service hands the entries over as a cloud API. From document to the books with no intermediate step.
In the invoicing software, quotes, orders, invoices and dunning notices sit in one place, filtered by state. Anyone allowed to see colleagues' documents has the whole firm in view, not just their own list.

Industry pageFee invoices by consulting day and seniority rate, travel expenses per client. One collective invoice at month end instead of loose individual documents.
Industry pageService retainers, SLA hours and licences bill themselves on the schedule booked. No forgotten billing run.
Industry pageInterim invoices by stage of completion, fixed-price and time-and-materials contracts. Change orders stay documented on the project.
Industry pageBill retainers and pass on freelancer costs. Interim and final invoice per campaign, cleanly separated.
Industry page“I save a lot of time writing invoices.”
“Staff in both support and project planning can see orders and invoices. That was not possible before.”
Case Study
A hypothetical practical example to illustrate how this works. Actual figures depend on your starting point, industry and implementation and are not guaranteed. A typical use case: an IT agency with 28 employees, separate time tracking, Excel lists and a stand-alone invoicing program.
Hours were exported monthly, prepared in Excel and transferred into the invoicing program. Entries were lost along the way, the billing run dragged on for days, and dunning only happened sporadically. Receivables grew because nobody saw the open items in one place.
In the invoicing software, hours, flat rates and travel expenses land directly on the order. The order shows what is billable and assembles the invoice from it. ZUGFeRD and XRechnung go out without switching tools, and the multi-stage dunning runs on its own once approved.

E-invoicing
When sending, teamspace produces a ZUGFeRD PDF and an XRechnung XML, depending on the setting. An incoming e-invoice is recognised by the barcode symbol in the mail attachment, and one click turns it into an incoming invoice with the data already read out.

Dunning
In the invoicing software, open items sort themselves into Open, Due and Overdue. If payment fails to arrive, the claim climbs four stages, each with its own deadline, fee and wording.

Scope
Six areas from the finance module. Incoming invoices, the DATEV interface and the online bank reconciliation belong to the enterprise edition.
The billing module starts in the office edition. Incoming invoices, the DATEV booking data service and the bank reconciliation belong to the enterprise edition. The prices shown are annual prices per user per month.

More modules
The billing module sits between sales, projects and time tracking. Eight further modules work on the same master data.
Incoming invoices
In the enterprise edition the invoicing software also manages the incoming side: documents are photographed or pulled in by drag and drop, an e-invoice is recognised by the barcode symbol in the mail attachment and becomes an incoming invoice. The DATEV booking data service transfers invoices, cancellations, incoming invoices and travel expenses to DATEV Unternehmen online as a certified cloud API, with no CSV export.
E-invoicing requirement
An e-invoice in the legal sense is a structured format such as the ZUGFeRD invoice or the XRechnung; a PDF sent by email does not qualify. The invoicing software handles both formats for sending and receiving. Since 2025 the obligation to receive applies in German B2B business, from 2027 the obligation to send for companies above 800,000 euros of prior-year revenue, and from 2028 for every company.
HOAI
Architecture and engineering practices bill their work phases under the German fee scale HOAI. The invoicing software models this through two line item types: a base value carries the estimated total construction costs, and every work phase sits on top of it as a percentage line item. Billing then runs through the same order as any other work, with interim payments and a final invoice.
Platform
Integration
The real lever in billing lies not in the document but in what it is made of. An invoice in teamspace is assembled from three sources that nobody has to retype.
The post-calculation on the order then compares plan, project actuals and invoice. That way you can read off the order whether the calculated margin really arrives in the invoice.
Security
Invoice data is sensitive: terms, margins, receivables. The invoicing software processes it exclusively in the EU, hosted in two geo-redundant, ISO 27001 certified data centres in Frankfurt am Main. On request you can activate the GoBD mode, which makes approved documents technically undeletable and enforces retention for ten years.
Migration
Invoicing software should take friction out, not create new friction. On the first day the company, logo and master data are set up and a test invoice is written; in the first week existing customers, open orders and products are added, via Excel, CSV or the REST API. After that, recurring invoices, dunning stages and, in the enterprise edition, the DATEV booking data service go live.
Quotes
Sales rarely fails on the first quote, it fails on the forgotten second contact. The invoicing software keeps every quote by status in one overview, creates a follow-up item with a deadline automatically on validation, and turns the accepted quote into the order with one click.
Templates
Quote, invoice and dunning notice should look as though they came from one house. The invoicing software sets up the layouts in the customer's corporate design, created once and valid for every document type. The product catalogue and price lists fill the line items, with tiered prices, volume discounts and a separate price list per customer.
Locations
Anyone working across several locations wants to appear separate on the outside and work together on the inside. Every location bills with its own invoice layout and its own number range, and reporting runs per location or across all of them. The separation of locations is available from the office edition onwards, where the billing module begins.

Fit
Invoicing software for a professional services firm convinces less through a pretty invoice printout than through an unbroken path from the quote to the incoming payment. Anyone selling work rather than products looks at three points in practice:
This is exactly where teamspace comes in: the order is the billing hub where booked hours, flat rates and dates collect until the finished invoice is ready.
