Billomat

What Is Billomat?

Germany's regulatory landscape for invoicing and bookkeeping is notoriously demanding. The GoBD framework (Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern) imposes strict requirements on how businesses create, store, and manage financial documents. For freelancers and small businesses navigating this landscape, choosing the wrong invoicing tool means compliance headaches down the road.

Billomat, founded in 2007 and headquartered in Cologne, was built specifically for this environment. It is a German online invoicing and accounting tool that prioritises compliance — GoBD, GDPR, and German tax law — while keeping things simple enough for non-accountants. The DATEV export feature, which allows seamless data transfer to tax advisors, is a standout for the German market.

Owned by Billomat GmbH & Co. KG, the platform serves primarily freelancers, sole traders, and small to medium-sized businesses in the DACH region (Germany, Austria, Switzerland). It competes with international tools like FreshBooks and Wave, but its deep integration with German tax and compliance infrastructure gives it a significant home-market advantage.

Billomat is not trying to be a full ERP system or a competitor to enterprise accounting platforms. Its strength lies in doing the fundamentals well — invoicing, expense tracking, payment reminders, and tax preparation — within a framework that German tax authorities will accept without question.

Key Features

GoBD-Compliant Document Management

Billomat's compliance infrastructure is its core selling point. All invoices, credit notes, and financial documents are stored in a tamper-proof, audit-ready format that meets GoBD requirements. This means every document has an immutable audit trail, proper sequential numbering, and long-term archival that satisfies German regulatory inspections. For freelancers who dread the Finanzamt, this is genuine peace of mind.

DATEV Export

The DATEV integration is arguably Billomat's most valuable feature for the German market. DATEV is the software system used by approximately 40,000 tax advisory firms across Germany. Billomat's export feature packages your accounting data in the exact format your tax advisor needs, eliminating manual data re-entry and reducing the risk of transcription errors. This alone can save hours during tax season.

Automated Invoicing and Payment Reminders

Recurring invoices can be configured to generate and send automatically on your chosen schedule — weekly, monthly, quarterly, or custom. When clients are late paying, Billomat sends graduated payment reminders (Mahnungen) that comply with German dunning procedures. You set the escalation timeline, and Billomat handles the rest. The reminder templates are customisable and available in multiple languages.

XRechnung and E-Invoicing

For businesses working with German public sector clients, Billomat supports the XRechnung format, which has been mandatory for government invoicing since 2020. It also supports ZUGFeRD, the hybrid PDF/XML format increasingly used across European B2B transactions. This forward-looking support for e-invoicing standards positions Billomat well as EU-wide e-invoicing mandates expand.

Bank Reconciliation

Billomat connects to your bank account and automatically matches incoming payments to outstanding invoices. This significantly reduces the time spent on manual bookkeeping. The matching algorithm handles partial payments and can learn from your corrections over time.

Pricing

Billomat's pricing starts at 9 EUR per month for the Solo plan, which covers up to 30 documents per month and a single user. For most freelancers sending fewer than 30 invoices monthly, this is sufficient. The Business plan at 18 EUR per month expands to 300 documents, three users, and adds recurring invoices and bank reconciliation. The Enterprise plan at 49 EUR per month removes document limits and supports up to 10 users.

Compared to international alternatives, Billomat is competitively priced for what it offers in the German market. FreshBooks starts at around 15 USD per month but lacks GoBD compliance and DATEV integration. SevDesk, a direct German competitor, starts at a similar price point but with different feature packaging.

The main pricing criticism is the lack of a free tier — only a 14-day trial is available. For freelancers just starting out with minimal invoicing needs, this is a barrier. However, for established freelancers and small businesses, the cost is modest relative to the compliance value and time savings on tax preparation.

Annual billing provides a discount of approximately 10-15%, making it worthwhile for users committed to the platform.

EU Compliance & Privacy

Billomat is exemplary in EU compliance. All data is stored on servers in Germany, the company is German-owned and operated, and the platform is built from the ground up for GDPR compliance. A data processing agreement (DPA) is available for business customers.

Beyond GDPR, Billomat's GoBD compliance means your financial records meet the highest German regulatory standards for digital bookkeeping. The audit trail is immutable, document numbering is sequential and verifiable, and all data is retained for the legally required periods.

For businesses in regulated industries or those handling sensitive financial data, Billomat's compliance posture is hard to beat among invoicing tools. The XRechnung and ZUGFeRD support further demonstrates commitment to European e-invoicing standards.

Who It's Best For

• German freelancers who need GoBD-compliant invoicing without learning complex accounting software.
• Small businesses in the DACH region that work with German tax advisors and need seamless DATEV export.
• Businesses invoicing the public sector that require XRechnung format support.
• Compliance-conscious SMEs that need an audit-ready financial document trail on EU servers.

The Verdict

Billomat does one thing exceptionally well: it makes German invoicing compliance effortless. The GoBD compliance, DATEV export, and XRechnung support form a trifecta that no international invoicing tool can match. For freelancers and small businesses in the DACH region, it removes genuine anxiety around tax compliance.

The trade-offs are real, though. The interface feels a generation behind modern SaaS design, multi-currency support is limited, and the German-market focus means it is less useful for international businesses. If you operate primarily in Germany and want invoicing software your Steuerberater will love, Billomat is an excellent choice. If you need a globally flexible invoicing platform, look at broader alternatives.

Frequently Asked Questions

How does Billomat compare to sevDesk?

Both are German invoicing tools with GoBD compliance and DATEV integration. SevDesk offers a slightly more modern interface and includes a free tier for basic use. Billomat has stronger XRechnung support and a more mature API for custom integrations. SevDesk is better for businesses wanting light accounting features alongside invoicing, while Billomat focuses more tightly on document management and invoicing workflows. The choice often comes down to interface preference and specific feature needs.

Can Billomat handle multi-currency invoicing?

Billomat supports creating invoices in different currencies, but its multi-currency capabilities are limited compared to international platforms like FreshBooks or Xero. Exchange rate handling is basic, and reporting is primarily EUR-denominated. For businesses that invoice predominantly in euros with occasional foreign currency transactions, it works adequately. For businesses with significant multi-currency needs, a more internationally focused tool may be more appropriate.

Does Billomat offer time tracking?

Yes. Billomat includes a built-in time tracking feature that lets you log billable hours against clients and projects. Tracked time can be converted directly into invoice line items. The time tracking is functional but basic — if you need detailed project management with time tracking, you may want to pair Billomat with a dedicated time tracking tool and use the API to connect them.

Is Billomat suitable for agencies or growing teams?

Billomat can work for small agencies, particularly on the Business (3 users) and Enterprise (10 users) plans. Role-based permissions let you control who can create invoices, view financial data, or manage client records. However, for agencies needing project management, detailed profitability tracking, or complex approval workflows, Billomat may feel too lean. It works best as an invoicing layer within a broader toolset rather than an all-in-one agency management platform.

What file formats does Billomat export?

Billomat exports invoices as PDF documents and supports DATEV format for tax advisor integration. Financial data can be exported as CSV for spreadsheet analysis. The platform also generates XRechnung (XML) and ZUGFeRD (PDF/A-3 with embedded XML) formats for e-invoicing compliance. API access on higher tiers allows pulling data in JSON format for custom reporting or integration with other business systems.
