About
Ah&Oh helps small teams manage ERP, online shop, CMS with application builder, task manager and POS on one shared data set, so orders, invoices and products are recorded once. Workspaces share a common knowledge base. Robin, the AI agent, handles routine tasks such as creating products from PDF or CSV files, preparing quotes, and coordinating fulfillment from stock checks to shipping labels and invoices. Robin works within the user's permissions, with human approval. ERP features include ZUGFeRD e-invoicing, a DATEV connection, a REST API and Model Context Protocol (MCP). The cloud service is hosted in Germany. The One plan includes the full ERP for €1 per month, and pricing is usage-based rather than based on users or revenue.

E-Rechnung Pro:
About
E-Rechnung Pro is a browser-based e-invoicing tool for freelancers, small businesses and accounting professionals that need to prepare ZUGFeRD or Factur-X documents. Users can create hybrid PDF/A-3 invoices with embedded XML in BASIC, EN 16931 and EXTENDED profiles, convert existing PDF invoices into hybrid files with OCR-assisted extraction for scans, and validate ZUGFeRD, Factur-X and XRechnung documents against EN 16931 rules. A document area provides history, status and search for invoices and validation results. The service runs online without installation and supports English, German, French and Ukrainian interfaces. Users can review validation messages and download files for further handling in their existing workflows.
