Home Nota Invoice Sync for Lexware Office – WooCommerce Integration

WooCommerce → Lexware Office

Real Lexware Office invoices, straight from WooCommerce

Nota Invoice Sync creates invoices in your Lexware Office account directly over the official API — no ERP, no middleware, no CSV exports. Lexware itself computes every tax amount, so low-value line items never get rejected over a rounding mismatch.

🧾 One-Click Invoices

From order to Lexware invoice — without leaving WordPress

Create a draft or a finalised Lexware Office invoice right from the order screen. The matching Lexware contact is found by email or created for you, and kept in sync when the customer’s billing address changes on a later order.

  • Draft (“Entwurf”) or finalised — your choice per shop
  • Contact lookup, creation and updates handled automatically
  • Invoice number and status shown on the order list and order screen
  • “Refresh invoice status” button picks up an invoice finalised directly in Lexware Office
  • Test mode: log the exact payload without sending anything

🇪🇺 Tax Treatment

German & EU tax handling that matches your accountant’s setup

Domestic, intra-community reverse charge, EU distance sales (OSS) or third-country export — the correct Lexware tax type is worked out from the order itself. And before anything goes wrong, the settings page compares your shop’s tax table with your Lexware account’s configuration and warns you about mismatches that would get invoices rejected.

  • Reverse charge detected from the order’s VAT-ID and zero tax
  • E-invoice (ZUGFeRD/XRechnung) format shown on every finalised invoice — ready for the 2027 B2B mandate
  • OSS mismatch warning — before the first rejected invoice
  • Kleinunternehmer (§19 UStG) accounts handled automatically
  • Trusts your shop’s tax decisions — never recalculates behind your back
⚡ Automatic Invoicing · PRO

Invoices that create themselves when the order does

Pick the order statuses that should trigger an invoice — processing, on hold, completed, or pending for pay-on-invoice shops — and the rest happens in the background, without making your customer wait at checkout.

  • Trigger on any combination of order statuses
  • Abandoned checkouts are detected and skipped, never invoiced
  • Runs queued in the background, retried on temporary API outages
  • Duplicate protection: one order can never become two invoices
⚡ When to create invoices
☑ Processing — payment received
☑ On hold — awaiting bank transfer
☐ Completed
☑ Pending — pay-on-invoice orders
ℹ Abandoned checkout detected for #10251 — skipped

📬 After the Invoice · PRO

PDF delivery, payment reminders and payment status — handled

The invoice PDF is attached to the WooCommerce order email automatically (finalised invoices only — a customer never receives an “Entwurf” watermark). Overdue invoices get up to three configurable reminder stages through Lexware’s own dunning documents. And twice a day, the plugin checks whether Lexware already shows an invoice as paid and notes it on the order.

  • PDF attached to the emails you choose
  • Three reminder stages with configurable day thresholds
  • Payment status read from Lexware — one-way, informational by design
  • Reminders stop automatically once Lexware already shows an invoice as paid
  • Compliance/GoBD export — one CSV of every finalised invoice, payment and credit note
  • Credit notes (Gutschrift) against any invoice — one click, or automatically on refund
  • PDF download — always for you, and optionally for customers via My Account
📦 Bulk Import · PRO

Invoice your last six months of orders — safely

Switching from another tool, or starting fresh mid-year? Filter existing orders by date and status and let the bulk importer work through them in small batches, paced to stay well inside Lexware’s API rate limit. Interrupted? It resumes exactly where it stopped.

  • Filter by date range and order status
  • Rate-limit-safe pacing — built for the API’s 2 requests/second cap
  • Resumable: survives timeouts, restarts and interruptions
  • Already-invoiced orders are always skipped, never duplicated

Frequently asked questions

No. Nota Invoice Sync is an independent product and is not affiliated with or endorsed by Haufe-Lexware GmbH & Co. KG. It talks to your Lexware Office account through the official public API, with an API key you create yourself. Lexware and Lexware Office are trademarks of Haufe-Lexware GmbH & Co. KG.

Yes. lexoffice is the former name of Lexware Office. The plugin uses the current api.lexware.io gateway.

No. The free version creates unlimited invoices — drafts or finalised — from the button on the order screen, with the complete tax treatment. Pro removes the manual step and adds everything that happens after the invoice: automation, PDF delivery, reminders, payment sync, credit notes and bulk import.

Any plan whose subscription includes access to the Public API (an API key created in Lexware Office’s Public API settings). Using the API itself costs nothing extra.

EUR only — that is a Lexware Office limitation, not a plugin one. Orders in another currency are skipped with a clear log entry instead of producing a wrong invoice.

Only when an invoice is created: the customer’s name, billing address, email and the order’s line items go to your own Lexware Office account over the official API. Nothing is sent to any other service, and nothing is sent at all until an invoice is actually created. Finalised invoices are kept by Lexware for ten years, as German accounting law (GoBD) requires.

It only ever creates documents and creates/updates the matching customer contacts. It never deletes anything, and uninstalling the plugin leaves your Lexware Office data completely untouched.

Yes — the plugin declares HPOS (High-Performance Order Storage) compatibility and works with both classic and HPOS order storage.
