Best accounting software in Germany for freelancers and sole traders — GDPR, ELSTER and e‑invoice ready

What German-compliant accounting software must actually do

Before comparing tools, you need to know what “compliant” means in the German context. The requirements go well beyond standard invoicing, and many popular international tools fall short in ways that only become obvious when the Finanzamt comes asking questions.

GoBD archiving: the baseline you cannot skip

GoBD rules set strict retention and auditability requirements for accounting documents. As of 1 January 2025, invoices and booking documents for self-employed persons are generally subject to an eight-year retention period, while books, inventories, and annual financial statements still require ten years. Either way, records must be stored in a tamper-evident, auditable format. You cannot delete or silently edit a posted invoice. The software must also maintain an immutable change log, machine-readable exports, and a documented procedure known as a Verfahrensdokumentation. If the Finanzamt audits you, they can demand a structured data export in a specific format. Platforms that archive only as editable PDFs or do not lock posted records are a real compliance risk, not a theoretical one.

ELSTER integration and the EÜR

Most freelancers in Germany use the Einnahmenüberschussrechnung (EÜR) rather than double-entry bookkeeping, which simplifies your obligations considerably. Your software still needs to calculate the EÜR from your recorded income and expenses and, ideally, submit it directly to the Finanzamt via ELSTER. Without native ELSTER integration, you are manually re-entering figures into a separate portal, which creates error risk and costs you time every quarter.

E-invoice mandates: ZUGFeRD and XRechnung

Germany is phasing in mandatory structured electronic invoices for B2B transactions, with the rollout running through 2027. Under the current transition schedule, larger suppliers face stricter issuance requirements from 1 January 2027, while many freelancers and smaller businesses in 2026 can still receive a standard PDF in some circumstances, though the direction of travel is clear. Compliant e-invoices must use ZUGFeRD or XRechnung format. Many tools support sending only, which is half the requirement. Check whether a platform handles both directions: creating outbound invoices in the correct format and importing and archiving inbound ones from suppliers.

How the leading platforms compare on the essentials

With those criteria in mind, here is how the main options stack up for German freelancers and small businesses in 2026.

Lexware Office and sevDesk: the mainstream defaults

Lexware Office and sevDesk are both widely recommended in German freelancer communities and independent reviews. Both cover VAT workflows, ELSTER submission, bank feeds, and DATEV export for handoff to a tax adviser. Lexware Office costs around 7.90 to 32.90 euros per month depending on the plan, while sevDesk’s plans run from roughly 9.90 to 30.90 euros per month (both as of September 2026, net). They are solid all-round choices; both work with German accounting terminology throughout, so some familiarity with it helps. Lexware and DATEV are largely German-first platforms; for sevDesk, we found no current information from the provider on an English interface (as of October 2026), so check the language options directly with the provider.

DATEV: powerful, but built for accounting firms

DATEV dominates the German professional accounting market and is the standard tool for Steuerberater. Its products are primarily aimed at tax advisers and their clients rather than at self-employed people who want to handle their own bookkeeping without professional support. Costs are modular and, according to market comparisons, can quickly reach 50 to 100 euros per month once you add the necessary components (approx., as of 2026, check with the provider). If your tax adviser uses DATEV and you want to collaborate directly, DATEV Unternehmen online is worth considering. If you are going it alone, it may add more complexity and cost than you need.

KontoVexa: built for the solo operator, not the accounting firm

KontoVexa is a cloud accounting platform built specifically for self-employed individuals and small businesses in Germany. According to the vendor, it combines invoicing, expense tracking, GoBD-compliant receipt archiving, EÜR, VAT management, and direct ELSTER submission in a single interface (EÜR, VAT returns and ELSTER from the Business plan). Its simplified mode is particularly useful: rather than confronting you with every feature at once, it shows only what is relevant to your business type and keeps the full view one click away. KontoVexa supports nine languages, including English, Turkish, Arabic, and Polish, making it well-suited to non-German-speaking freelancers who need to manage German-compliant bookkeeping in their own language. Your data is hosted in Frankfurt am Main in line with the GDPR, and sensitive data such as IBANs and tax numbers is additionally encrypted.

KontoVexa in practice: how it handles the tasks that matter

Here is how KontoVexa handles the three tasks German freelancers repeat most often.

Creating a compliant e-invoice

From the invoice screen, you select the client and add line items with the correct VAT rate. KontoVexa then generates the invoice with all mandatory fields pre-populated: your tax number, the correct sequential invoice number, the tax breakdown, and the due date. The output is a ZUGFeRD PDF (profile EN 16931) that embeds a structured XML file, satisfying both the visual and machine-readable e-invoice requirement for B2B transactions; you can also create an XRechnung. There is no separate export step or format conversion needed. As a Kleinunternehmer you issue invoices without VAT, with the § 19 UStG note, and KontoVexa monitors the turnover limits of €25,000 and €100,000.

Submitting a VAT prepayment via ELSTER

On the Business and Pro plans, KontoVexa takes your recorded income and expenses for the relevant period and calculates your Umsatzsteuer-Voranmeldung with the official Kennzahlen. You review the figures, KontoVexa checks them with ERiC, the official ELSTER interface, and transmits them directly to the Finanzamt using your ELSTER certificate; the transmission log is stored in your account. This replaces the manual process of downloading figures, opening the ELSTER portal, re-entering numbers, and saving the confirmation PDF somewhere you can find it in three years. Note that you will need a valid ELSTER certificate configured in your account to use this workflow.

Archiving a receipt with GoBD compliance

You photograph a receipt on your phone or upload a file. You link it to the booking with the expense category and tax rate, and KontoVexa stores it in an unalterable archive for ten years, in line with GoBD retention requirements. Booked records are not overwritten: corrections are made through reversal entries, and every change is recorded in the audit log. If an audit request arrives, you export reports and the cash book as CSV or XLSX directly from the platform, no scrambling through email attachments or desktop folders. KontoVexa does not offer an export in the tax administration’s own audit format, so agree the form of data handover with the auditor or your tax adviser.

Pricing reality check: what you actually pay in 2026

Pricing comparisons are complicated: many tools advertise entry-level plans that exclude the compliance features most freelancers actually need. The headline number rarely reflects what you will pay once you add ELSTER submission and full bookkeeping.

What the entry prices include (and exclude)

According to market comparisons, Lexware Office’s cheapest tier at around 7.90 euros per month covers invoicing and receipt storage but not the full bookkeeping and ELSTER submission workflow. sevDesk’s invoicing plan, from around 9.90 euros per month, does not include the accounting features needed for the EÜR; according to market comparisons, these start with its Buchhaltung plan. FastBill’s Solo plan at around 9 to 10 euros per month is positioned primarily as an invoicing tool rather than a full accounting solution (approx., as of 2026, check with the provider). To get the features that matter for German compliance across these platforms, expect to pay roughly 20 to 26 euros per month (as of 2026, net).

Where KontoVexa fits on price

KontoVexa is positioned as an affordable, all-in-one alternative with three transparent plans. The Start plan (9.90 euros per month or 99 euros per year, net) covers invoicing, e-invoicing with ZUGFeRD and XRechnung (create and receive), income and expense tracking, and GoBD receipt archiving. The EÜR, the advance VAT return and direct ELSTER submission are included in the Business plan (22.90 euros per month or 199 euros per year, net), together with SKR03 bookkeeping, bank statement import and free access for your tax adviser. Compared to the true cost of a compliant sevDesk or Lexware Office setup with all the necessary modules, KontoVexa aims to offer a short path to full compliance at a competitive monthly price. You can try it free for 30 days without a credit card. Check the current pricing page for the latest plan details.

Choosing the right tool for your situation

No single platform is the right accounting software for every freelancer or small business in Germany. Your profile determines which trade-offs matter most.

German-speaking solo freelancer managing your own books: If you are comfortable working in German, have a straightforward EÜR setup, and want to avoid a tax adviser for routine tasks, both KontoVexa and Lexware Office are strong candidates. KontoVexa’s simplified mode reduces the learning curve. Lexware Office is the better choice if your tax adviser specifically requests DATEV-format data exports and that working relationship is central to how you operate: KontoVexa offers no DATEV export, but on the Business plan your tax adviser gets free access of their own.

Expat or multilingual freelancer working under German tax law: If you registered your Gewerbe or freelance activity in Germany but work in English, Turkish, Arabic, Polish, or another supported language, KontoVexa is designed to let you manage your bookkeeping in your preferred language while producing fully German-compliant outputs for the Finanzamt. Among the tools reviewed here, it offers the widest choice of interface languages (nine); if you only need English, also check the language options of the other providers.

Growing small business or freelancer working with a tax adviser? If your business is scaling, you have employees, or your Steuerberater needs DATEV-format exports as a non-negotiable, sevDesk or Lexware Office on their mid-range accounting plans are the better fit. DATEV itself makes sense only when your tax adviser is driving the accounting workflow and you are contributing documents rather than managing the ledger yourself.

Before signing up for any platform, run through this checklist:

• Does it support ELSTER submission directly, not just export to a separate portal?
• Can it create and receive ZUGFeRD/XRechnung e-invoices?
• Is GoBD-compliant archiving included in the plan you are evaluating?
• Does it handle the Kleinunternehmerregelung if you are VAT-exempt?
• Is the interface available in a language you are comfortable working in?
• What does the plan you actually need cost once you include the compliance features?

The bottom line for freelancers and sole traders

The best accounting software in Germany for a freelancer is not necessarily the most well-known one or the one your tax adviser uses. It is the one that covers GoBD archiving, ELSTER submission, e-invoicing, and EÜR without requiring you to buy three separate modules or navigate an interface built for accounting professionals.

KontoVexa was designed to answer exactly that problem: full German compliance in a simplified interface that adapts to your business type, with support for nine languages so the rules stay clear regardless of your native tongue. The e-invoice mandate will only tighten through 2027, with stricter issuance thresholds taking effect from 1 January 2027. Getting your accounting setup right now saves a significant amount of pain later.

If you are evaluating cloud accounting software for your self-employed setup in Germany, the practical next step is to try KontoVexa and test the ELSTER submission and e-invoice workflow against your current process. You will quickly see whether it fits.
