What is Invoice Generation?
The Invoice Generation skill is a specialized tool within the Openclaw Skills library designed to automate the creation of high-quality financial documents. By utilizing the each::sense AI, it allows developers and business owners to generate visually appealing, accurate documents like invoices, receipts, and purchase orders through simple natural language prompts.
This skill is built for versatility, supporting everything from minimalist digital receipts to complex international invoices with multi-currency support and localized tax compliance. As part of the Openclaw Skills ecosystem, it bridges the gap between raw financial data and professional, client-ready documentation, offering both high-performance (max) and cost-effective (eco) generation modes.
Invoice Generation Use Cases
- Automating monthly billing for service providers and freelancers.
- Generating instant payment receipts for e-commerce transactions.
- Creating professional project quotes and estimates for client approval.
- Issuing credit notes and refund adjustments for accounting accuracy.
- Streamlining procurement with automated purchase order generation.
How Invoice Generation Works
- The user provides transaction details (parties involved, items, prices) via an API request to Openclaw Skills.
- The AI analyzes the input to determine the document type, such as an invoice or a quote.
- Dynamic calculations are performed for sub-totals, taxes (VAT/GST), and grand totals based on the provided rates.
- Branding elements like logos and color schemes are applied to the document layout.
- The finalized document is generated as a structured output, ready for digital delivery or printing.
- Optional multi-turn sessions allow the user to refine the design or add details iteratively.
Invoice Generation Setup
To integrate this skill into your workflow, you need an API key from eachlabs. Use the following bash command to generate your first document:
curl -X POST https://sense.eachlabs.run/chat \
-H "Content-Type: application/json" \
-H "X-API-Key: $EACHLABS_API_KEY" \
-H "Accept: text/event-stream" \
-d '{
"message": "Generate a professional invoice for web development services, $2,500 total, due in 30 days",
"mode": "max"
}'
