zepdesk.deAll Modules and Features
Five core modules and the full range of features in every plan, built as one coherent whole
Quotes and Invoices
The document flow from quote through order and delivery note to invoice runs as a single process, and you carry each document over from the previous one with a click, with no duplicate entry. When a quote is accepted, you convert it straight into an invoice. Unlimited invoices in every plan, including recurring ones for subscriptions and maintenance contracts, with live preview and an individual PDF layout per company (logo, colors, footer texts). Incoming payments are matched automatically.
E-Invoicing
You send and receive XRechnung, ZUGFeRD and hybrid PDF in a legally compliant way, in every plan at no extra charge. For public sector clients and mandatory B2B areas, you store the Leitweg-ID (routing ID) once in the customer profile, after which ZepDesk generates the valid e-invoice to authorities with a click. The system automatically detects incoming e-invoices on upload and takes the data directly from the XML structure.
Receipts and OCR
You capture receipts by smartphone photo, email inbox or drag and drop. The OCR runs on EU servers and uses no external AI services; it recognizes the supplier, date, document number and amounts including VAT and proposes the posting and the matching bank transaction. If a receipt already contains ZUGFeRD or XRechnung data, this is taken over without text recognition. Storage is GoBD-compliant, with reversal instead of deletion and a complete history.
Banking and Reconciliation
You import bank statements via CSV, MT940 and CAMT from any German bank. ZepDesk assigns each transaction to its receipt or open invoice and proposes the matching entry. You manage SEPA direct debits including mandates and PAIN.008 export. Direct The direct bank connection via finAPI (PSD2) is already available, and file import works alongside it.
Double-Entry Bookkeeping and EÜR
Choose EÜR (cash-basis accounting) or double-entry bookkeeping with the SKR03 or SKR04 chart of accounts, cleanly separated per company and extendable with your own accounts at any time. The bookkeeping is GoBD-compliant, with a complete general ledger and audit-proof storage.
Fixed Assets, Provisions and Closing
For corporations, ZepDesk covers fixed assets with straight-line and declining-balance depreciation (AfA), low-value assets, pooled depreciation and an asset movement schedule, plus provisions, accruals and deferrals, period-end closing and a legally compliant cash book for cash transactions.
Dunning
You start a three-stage dunning process with configurable fees and default interest directly from the open invoice.
Taxes and ELSTER
Filings and returns are generated directly from the postings, with no re-entry and no recalculation. EÜR and UStVA (advance VAT return) for the self-employed, KSt (corporate income tax), GewSt (trade tax, with a configurable multiplier per municipality) and E-Bilanz for corporations. In total, ZepDesk generates 14 data types as official ELSTER XML; you will find the details in the ELSTER section.
Reports and Dashboard
BWA (business analysis), EÜR, UStVA, trial balance and revenue trend are generated live from the posting journal, always up to date and without a series of clicks. The dashboard shows revenue, open items, the VAT return due and new receipts as key figures right on the home page.
Master Data, CRM and Multi-Company
Customers with purchase history, open items, VAT ID, Leitweg-ID and GDPR consents, items with price tiers and tax rates, suppliers with reverse-charge logic. For GmbH and AG, shareholders with capital distribution, corporate bodies and meeting minutes are added. You manage several companies in a single login, with separate accounting circles, individual branding and a company switcher; one company is included.
DATEV Export and Tax Advisor Access
You export postings, debtors and creditors in the DATEV EXTF format (v7.0, SKR03 or SKR04) as a ZIP for the tax firm, including the stored consultant and client number. Your tax advisor also gets a dedicated role with read access and export, at no extra charge.
Tax audit and auditor export
For a tax audit ZepDesk produces the Z3 data export under section 147 (6) of the German Fiscal Code in IDEA format (data carrier handover with all postings) plus the DSFinV-K export for cash transactions. The audit-proof, GoBD-compliant records are kept for ten years.
AI Assistant (BYOK) and REST API
The ZepDesk assistant carries out tasks directly in the system and makes every step traceable. It works on a Bring Your Own Key principle: you store your own API key (Claude or OpenAI, for example) or use a local model. Requests go exclusively to your own provider, and your data stays with you. Without a key, the assistant remains inactive and the rest of the software runs independently. An open REST API for your own integrations is included.
Association, Foundation and Corporation
For associations and foundations, ZepDesk offers sphere-based accounting under § 64 AO (four spheres), donation receipts based on the official template, and a monitor for the 50,000 EUR exemption limit, use of funds and reserves. Corporations receive the balance sheet, E-Bilanz, KSt and GewSt through to period-end closing.
ELSTER Integration with 14 Data Types
ZepDesk generates your tax office filings as official ELSTER XML, directly from the postings, one click per filing, with ERiC direct submission or upload to Mein ELSTER.
The 14 data types at a glance: UStVA (advance VAT return), UStE (annual VAT return), USt 1 H (special VAT prepayment), Anlage EÜR (cash-basis accounting schedule), GewSt (trade tax), KSt (corporate income tax), KapESt (investment income tax), Lohnsteuer-Anmeldung (payroll tax return), assessment under § 180 AO, business income tax (Anlage S and G), E-Bilanz under § 5b EStG, EC Sales List (Zusammenfassende Meldung, ZM), OSS and property tax (Grundsteuer). Submission is by ERiC direct dispatch or as official XML for upload to Mein ELSTER. The complete private income tax return (Anlage N, KAP, V and others) remains with Mein ELSTER or your tax advisor.
