For many back-office and customer service teams, order entry is still a sequence of copy-paste operations from emails, attached PDFs, and B2B portals into the company ERP. A workflow that doesn't scale, generates errors, and slows down customer response times.
In this guide we look in detail at how purchase order automation works, which documents can be processed, how it integrates with major ERPs, and which criteria to use when choosing the right solution for your company.
1. Why Manual Order Entry Is Still a Problem
Despite digitalization having touched almost every business process, incoming order management often remains manual. The reasons are historical: customers send orders in different formats (PDF, Excel, structured emails, digitized faxes), and building a point-to-point EDI integration for each customer is expensive and inflexible.
The result is a process that still looks like this:
- The customer sends an order via email with an attached PDF
- The operator opens the PDF, reads it, opens the ERP
- Manually types each line: item code, description, quantity, price, delivery address
- Saves the order, sends confirmation to the customer
- The manager reviews and approves
The hidden costs of this process are significant:
- Operational time: an average of 5–15 minutes per order, multiplied by hundreds or thousands of orders per month
- Typing errors: rates between 2% and 5%, generating returns, complaints, credit notes, and customer friction
- Bottleneck during peaks: the capacity to process orders is limited by available staff, not by demand
- Lack of traceability: difficult to reconstruct who entered what and when
2. How Purchase Order Automation Works
A purchase order automation system automatically extracts data from any incoming order document and transfers it into the company ERP, without the operator having to manually re-enter any line.
The core of the system is an Artificial Intelligence engine trained to:
- Recognize the document as a purchase order, regardless of format
- Extract key fields: header (customer, date, order number, delivery address), lines (item code, description, quantity, price, unit of measure)
- Normalize the data: map customer item codes to internal codes, apply correct price lists, handle specific business rules
- Flag exceptions: unrecognized codes, anomalous quantities, price discrepancies — before they reach the ERP
Unlike template-based systems, an AI engine doesn't "break" when a customer changes their layout or adds a column to their PDF. It learns from the document's patterns and adapts over time.
3. Which Documents Can Be Processed
A mature order automation solution must be able to handle all the formats in which customers send their orders:
- Structured PDFs (generated by the customer's ERP software)
- Scanned PDFs (paper documents photographed or scanned)
- Excel and CSV files with order line tables
- Free-text emails, where the order is written in the body of the message
- Images (JPG, PNG) of printed orders
- EDI and XML streams for more structured customers
The ability to handle all these formats in a single workflow is what differentiates an AI platform from a simple file import solution.
4. How It Integrates with Major ERPs
ERP integration is the critical point of any order automation project. The most common methods are:
Native APIs
The most robust and traceable method. The automation system calls the ERP's APIs to create the order directly, with complete logs of every operation. Supported by major modern ERPs: SAP, Odoo, Microsoft Dynamics 365, Oracle NetSuite.
Structured file import
In the absence of APIs, the system generates a file in the ERP's import format (CSV, XML, JSON) that is loaded automatically. Less elegant but often sufficient to get started.
A native API integration is preferable to file-based solutions because it is faster, traceable, and less prone to synchronization errors.

5. The End-to-End Operational Flow
Here is what the process looks like with an active automation solution:
- Automatic receipt: the order arrives via email, B2B portal, or shared folder and is captured without human intervention.
- Classification: the AI engine recognizes the document as a purchase order and separates it from any other attachments (confirmations, shipping instructions, etc.).
- Data extraction: all relevant fields are extracted with a confidence score associated with each field.
- Validation and matching: item codes are matched to the internal catalog; discrepancies are flagged for review.
- Sending to ERP: high-confidence fields are automatically sent to the ERP; uncertain ones are queued for human review.
- Customer confirmation: once the order is recorded, the confirmation is sent automatically.
The operator intervenes only to validate exceptions — not to re-enter every single line.
6. Real Use Case: An Italian Manufacturing Company
The following data comes from a real project conducted by Typelens with an Italian industrial automation and plant engineering company, with approximately €20 million in annual revenue.
The problem
The company manually managed 80,000 lines of delivery notes and orders each year. Each document required an average of 5 minutes of manual work: opening the PDF, reading it, entering it into the ERP, verifying. A repetitive, slow, and error-prone process.
The solution
The implementation of Typelens made it possible to automate the entire workflow: document capture, data extraction with OCR + AI, matching with catalog items, and automatic sending to the ERP. The operator intervenes only for final validation and exception handling.
The results
- Time per document: from 5 minutes to less than 1 minute (80% reduction)
- Hours recovered: over 1,100 hours per year (equivalent to 0.5 FTE)
- Estimated savings: approximately €12,500 in annual operating costs
- Scalability: the same logic was extended to supplier invoices and commercial quotes
The same architecture applied to delivery notes is directly transferable to incoming purchase orders, with the same extraction, matching, and ERP integration logic.

7. How to Choose an Order Automation Solution
Not all solutions are equal. Here are the key criteria to evaluate before choosing an automated order import platform:
Format handling
The solution must natively handle PDFs (structured and scanned), Excel, emails, images, and EDI streams. Check whether it uses rigid templates (which "break" when the customer changes their layout) or flexible AI models that automatically adapt to new formats.
Accuracy and confidence score
Each extracted field should have an associated confidence score. Fields below the threshold are flagged for human review (Human-in-the-Loop), while high-confidence ones pass automatically. This balances speed and control.
Integration with your ERP
Verify that pre-configured connectors exist for your ERP. A native API integration is preferable to file-based solutions because it is faster, traceable, and less prone to synchronization errors.
Exception handling
A good system is not one that "never makes mistakes", but one that handles errors in a structured way. Verify that there is a clear interface to review exceptions, correct them, and use them to improve the model over time.
Scalability and pricing
Evaluate the pricing model: per processed document, per monthly volume, or flat fee. Verify that the solution handles seasonal peaks without performance degradation or unexpected costs.
Security and traceability
Every processed order should have a complete log: who did what, when, with what confidence level. This is essential both for internal audits and for handling any disputes with customers or suppliers.
Conclusion
Purchase order automation is not a future project: it is an operational lever already available, with measurable ROI within a few months. The transition from manual copy-paste to automated import changes the role of the back office: from data entry executor to process controller. Fewer errors, faster response times, and the ability to scale without growing the team. If your company still receives orders via email or PDF and enters them manually into the ERP, now is the time to evaluate a solution.
