Rebuild Your Procure-to-Pay Process with AI Automation

Most manufacturing SMBs start by using their accounting software's built-in tools, like QuickBooks Bill Pay. These tools manage payments but do not automate the tedious data entry from vendor invoices. An accounts payable clerk still spends hours manually keying in invoice numbers, line items, and due dates, a process where a single typo can lead to a costly overpayment.

To solve the data entry problem, some teams try dedicated OCR software. An OCR tool can extract text from a PDF, but it does not understand context. It might pull '12/25/2024' but cannot reliably identify it as the 'due_date' field across a dozen different invoice layouts. This forces developers to write brittle, template-based rules for each vendor, which break the moment a vendor changes their invoice design.

AP automation platforms seem like the next logical step, but they introduce new problems. They charge per invoice or have high monthly minimums, penalizing volume. A manufacturer processing 1,000 invoices per month can face a $500 monthly bill before user fees. These platforms also lack the ability to run custom validation logic, like checking a PO line item against a custom field in a proprietary inventory management system before approving payment.

Syntora's approach to procure-to-pay automation for manufacturers begins with a detailed discovery phase to understand your specific vendor ecosystem and integration points. The goal is to design a system that not only automates invoice processing but also integrates deeply with your existing financial tools.

The ingestion pipeline would be designed to automatically pull new invoices from various sources, such as dedicated email inboxes or file shares. This process often utilizes services like AWS Lambda for scalable processing. For document interpretation, the system would employ Amazon Textract, ensuring high-fidelity OCR for both digital PDFs and scanned paper documents, even those with complex table structures.

Following OCR, the raw text from Textract would be processed by a large language model API, such as Claude 3 Sonnet. Syntora would define a precise JSON schema with key fields like Invoice ID, PO Number, Vendor Name, Line Items, and Total, to extract structured data. This methodology aims to significantly reduce the manual effort involved in data entry.

A custom FastAPI service would be developed for data validation. This Python application would verify extracted data against your ERP, checking PO numbers and line-item prices, and identifying potential duplicates. Validated invoices would then be pushed directly to your accounting system's API, whether NetSuite, QuickBooks, or a custom platform. Drawing from our experience building an internal accounting automation system using Express.js and PostgreSQL, which handles complex transaction categorization and journal entries, Syntora understands the importance of a robust audit trail. Your procure-to-pay system would use a Postgres database, such as Supabase, to log every transaction and its status for compliance and tracking.

The system would be deployed as a serverless application, optimized for operational efficiency. Syntora implements structured logging using `structlog` and configures monitoring tools like CloudWatch. This ensures that any processing issues, such as an elevated API error rate, trigger immediate alerts, allowing for prompt investigation and resolution.
