German invoicing for Kleinunternehmer in WordPress: quotes → invoices in one click, §14 UStG fields, PDF & email. Pro adds DATEV, ZUGFeRD & GoBD.

== Description ==

KleinBooks brings the German business workflow — **Angebot → Rechnung** (quote → invoice) — directly into your own WordPress admin. No second tool, no monthly SaaS subscription. It is built for Kleinunternehmer and small businesses who already run their site on WordPress.

= Free =

* Write quotes/offers (Angebote) and convert them to an invoice in one click
* Create invoices with the correct German mandatory fields (§14 UStG basics)
* Generate clean PDF invoices & quotes (DomPDF) and send them by email
* Manage your clients and customers
* Log business expenses
* A simple dashboard with a revenue overview

= Pro =

Upgrade the day you need to be audit-ready and mandate-ready:

* **ZUGFeRD / Factur-X e-invoicing** — get ready for the 2027/2028 German e-invoice mandate
* **DATEV export** (EXTF 700, SKR03/SKR04) for your tax advisor
* **GoBD compliance lock** — tamper-proof, immutable invoices with proper Storno (cancellation)
* **AfA / Abschreibung** — depreciation tracking

KleinBooks Free is an invoicing tool. Compliance features (GoBD lock, DATEV export, e-invoicing) are part of KleinBooks Pro.

== Installation ==

1. Install KleinBooks from the WordPress plugin directory, or upload it to `/wp-content/plugins/kleinbooks`.
2. Activate the plugin through the **Plugins** screen in WordPress.
3. Open **KleinBooks** in the admin menu and create your first invoice.

== Frequently Asked Questions ==

= Is KleinBooks free? =

Yes. The core invoicing features are free and fully functional. The compliance features (ZUGFeRD e-invoicing, DATEV export, GoBD lock, AfA) are part of KleinBooks Pro.

= Does the free version make me GoBD-compliant? =

No. The free version is an invoicing tool. GoBD compliance, audit-proof immutability, DATEV export and e-invoicing are part of KleinBooks Pro.

= Do I need an external service or account? =

No. KleinBooks runs entirely inside your own WordPress install. Your invoicing data stays on your own site.

= Can I write quotes (Angebote)? =

Yes, in the free version. Write an Angebot, send it as a PDF by email, and when the client accepts, convert it into a draft invoice in one click — the invoice stays editable so you can make any last changes before sending. The quote and the invoice stay cross-linked so you always see where each one came from.
