Invoicing software 2026: GoBD- and e-invoice-ready, without accounting knowledge

Anyone looking for invoicing software in 2026 usually has two questions in mind: is everything legally sound – and can I manage without accounting knowledge? This overview shows what matters in modern invoicing software and how Easy Invoice in the PepperTools Office Cloud solves it.

What invoicing software needs to do in 2026

Two points are legally decisive:

• GoBD (German principles for proper bookkeeping): invoices must be tamper-proof, traceable and kept for the statutory periods (usually 8 or 10 years). Good software supports GoBD-compliant invoicing by archiving documents in an audit-proof way and logging changes.
• E-invoicing: in the B2B sector the electronic invoice is coming – the software should handle the German standard formats XRechnung and ZUGFeRD. What applies when is covered in our article on the e-invoicing obligation 2027 and 2028.

Then there are the basics: clean master data, all document types (quote, order confirmation, delivery note, invoice, credit note, cancellation) and a professional PDF with your own logo. How a correct invoice is structured is explained in our guide to writing an invoice.

No idea about accounting? You don't need any

The most common reason tradespeople and service providers put off bookkeeping: the jargon. That's exactly what we take off your hands. In Easy Invoice you simply assign an incoming payment to the matching invoice – the system does the rest in the background. The corresponding accounting entries are created automatically, neatly prepared for your tax adviser.

This is made possible by an integrated payment workflow: PayPal statements and bank statements (e.g. from StarMoney) are imported, and clear-cut payments are suggested directly for the right document. You confirm – done. This keeps your open items up to date without you booking a single entry by hand.

Suitable for small businesses too

One of the most common questions: is this also suitable for small businesses (Kleinunternehmer)? Yes. As a small business under § 19 of the German VAT Act you use the platform without any problem – your documents are correctly issued without VAT shown and with the appropriate note. And if you outgrow the small-business scheme or are subject to standard taxation, you book just as cleanly using chart of accounts SKR03 or SKR04 – with either accrual or cash-basis taxation. So the software fits from your first document to your growth.

Work anywhere – without installation

Easy Invoice runs in the cloud: you open it directly in the browser on any PC, without installation and with automatic updates. Anyone who has been using the Easy Invoice desktop software can transfer their entire data set (customers, items, documents, payments) to the cloud – without starting over.

Always with you: the app for Android and iOS

Your office fits in your pocket: the mobile app is available for Android and iOS. Master data, documents and contacts are available everywhere – at the customer's site, in the field or on the construction site, even without a laptop. You can see the current status of your orders and open receivables at any time and check directly on site, instead of gathering information later in the office. And right on the spot you can capture notes and reminders about the customer – so the next appointment is always prepared.

In 9 languages – interface, app and documents

Multilingualism is no half-measure at Easy Invoice: the landing page, the SaaS platform and the mobile apps are fully available in 9 languages – German, English, Spanish, French, Italian, Dutch, Polish, Russian and Turkish. Every employee works in their own language – on the same shared data set.

And it doesn't stop at the interface: for each customer you set which language the documents are generated in. The Italian customer gets their quote in Italian, the Polish one their invoice in Polish – fully localized PDFs including column headers, footers and dunning texts, without the user having to switch.

Secure and legally sound – your data stays in Germany

• Hosting in Germany, processing in compliance with the GDPR.
• Automatic backups – you don't have to worry about anything.
• Tamper-proof archiving of outgoing documents and your e-invoices in secure object storage; once archived, the document stays unchanged.
• Everything traceable – processes are logged and can be retrieved specifically when needed (e.g. a tax audit).
• Multi-step login with optional two-factor authentication and strict tenant separation.

Built for tradespeople and service providers

• Partial and final invoices: partial invoices during the project, a final invoice at the end with correctly offset advance payments – ideal for construction and longer projects.
• Dunning: multi-stage reminders automatically, so your money arrives on time (more in the dunning guide).
• Reports & tax-adviser export: document journals, EUR (income-surplus) analysis and exports in common handover formats – a clean basis for the VAT advance return as well.

Flexible instead of a long contract

Easy Invoice adapts to your business: cancellable monthly (up to one day before expiry), multiple users per tenant – your tax firm can join in too – and user seats can be added as needed. Various packages with different feature scopes cover everything – from the occasional invoice writer to daily use with a larger volume of documents.

Best to see for yourself: try it for 10 days at your leisure – with no bank details required.
