💡 Challenge
Accounts-payable still receives hundreds of PDF invoices, reminders, and receipts every month.
Manual keying of amounts, due dates, and suppliers is slow, costly, and error-prone.
✅ Solution
Combine any free-tier OCR connector (Adobe PDF Services, Cloudmersive PDF/OCR, or Azure Document Intelligence Read F0) with Azure AI Language – Abstractive Summarization F0.
One Power Automate flow extracts text from each PDF and returns a clear, three-bullet summary - at zero cost up to 500 pages per month.
🔧 How It’s Done
Here’s the 5-step recipe:
- Trigger – When a file is created (SharePoint / OneDrive → folder Incoming Invoices).
- OCR action – pick one connector:
🔸 Adobe PDF Services (standard) 🔸 Cloudmersive PDF (premium) 🔸 Azure Read F0 (standard) - Compose – capture the plain OCR text (
contentortextfield). - HTTP – call Azure AI Language
/language:analyze-textwith
kind=AbstractiveSummarizationandsummaryLength=short. - Post-Process – send a Teams/Outlook summary, store in Dataverse table InvoiceSummaries, then move the PDF to an Archive folder.
🎉 Result
Every new invoice now triggers an automated pipeline - OCR → AI summary → messaging/storage.
Finance receives key facts (total, due date, supplier) within seconds and can focus on approvals instead of data entry.

🛠️ FAQ
1. Do I need a premium licence?
Only if you choose Cloudmersive (premium connector). Adobe PDF Services and Azure Read F0 use standard or HTTP actions.
2. What about multi-page PDFs with Azure Read F0?
The free tier processes only the first two pages. Split longer invoices or upgrade to S0 (€0.01 / page).
3. How do I avoid hitting Azure AI token limits?
F0 allows 16 384 characters per request - trim or chunk OCR text for very long invoices.
