I will build ai invoice processing automation with n8n, ocr and approval
Anowar Hossain
About this gig
Need AI invoice processing without manual data entry?
I will build an n8n workflow that reads your vendor bills with OCR and AI, flags errors and duplicates, saves the data and sends each one for approval.
Flow: email or folder -> extract -> validate -> duplicate check -> save -> approve -> alert.
WHAT I AUTOMATE
- Invoice data extraction from Gmail, Outlook or a folder (PDF, scan, image)
- Vendor, bill number, dates, subtotal, tax, total (line items from Standard)
- Validation, duplicate detection and status tracking (Standard+)
- Save to Google Sheets or Airtable; database/accounting via API (Premium/extra)
- Approval workflow via Slack, Telegram or email (Premium/extra)
- Unclear files flagged for manual review; error logs in Premium
Great for accounts payable teams, bookkeepers and small businesses.
YOU RECEIVE
A tested n8n workflow, setup help, simple documentation and free fix support (7-30 days).
GOOD TO KNOW
You provide your n8n workspace and AI/OCR API keys (billed by the provider). Accuracy depends on scan quality, so uncertain results go to manual review.
Note: Message me first with 2-3 redacted sample bills.

FAQ
What is included in each package?
Basic: data extraction from 1 email or folder into Sheets or Airtable. Standard adds line items, validation, duplicate detection, status tracking and alerts. Premium adds approvals, accounting/DB sync, error logs, docs, video and a 2nd source.
How fast is delivery and what if I need changes?
Delivery is 2, 4 or 7 days (Basic, Standard, Premium) once I have your sample invoices and access. Revisions: 2, 3 or 5. After delivery I fix issues in the workflow for 7, 14 or 30 days at no extra cost.
What invoice types and data can you process?
PDF, scanned, image and email-attachment bills from different vendors: vendor, number, dates, tax, total, currency and line items (Standard and up). Very blurry or handwritten files may need manual review, so I add a review path.
Do you guarantee 100% accurate extraction?
No tool can promise that. Basic flags unreadable files; Standard adds validation and a Needs Review status, so unclear or mismatched invoices go to a person instead of being saved wrongly.
How does the invoice approval workflow work?
Included in Premium, or add the Approval Workflow extra. Approvers get Approve/Reject buttons in Slack, Telegram or email and the decision is saved. Slack/Telegram buttons need your n8n reachable over public HTTPS.
How do you detect duplicate invoices?
I compare vendor, bill number and total with earlier records. Matches are marked Duplicate instead of being saved or approved again. Included from Standard.
Can you connect QuickBooks, Xero or my ERP?
Yes, if the tool has an API or an n8n node. Accounting/database sync is in Premium, or add the QuickBooks Xero Sync extra. For other tools, message me before ordering.
Which AI/OCR do you use, and is my data safe?
OpenAI, Gemini, Claude or a dedicated OCR API, chosen for your invoices and budget. Everything runs in your own n8n and accounts, API usage is billed to you, and I never ask for passwords: credentials are added inside your n8n.
Do I need my own n8n account?
Yes, n8n Cloud or self-hosted. If you don't have one yet, I will guide you through the sign-up and connecting your credentials. I build inside your workspace.
Do you give accounting or tax advice?
No. I automate the process you already use: data capture, checks and approvals. Accounting rules and tax decisions stay with you or your accountant.
