Choose an LLM if…
You want to extract order information, understand unstructured emails, or experiment with AI. It's a strong starting point, but it isn't a complete order-processing system.
Extraflow vs n8n vs LLMs: Which Actually Gets Customer Orders Into Your ERP?
An honest comparison of AI, workflow automation, and purpose-built order processing.
Who makes sure the right order reaches your ERP?
An LLM can read your customer's email. n8n can move the data between systems.
That's the difference between automating a task and automating the entire order process.
Re: Plasterboard panels order
Hi, please send us 2 pallets of plasterboard panels, same as our last order, at our usual agreed price.
Standalone LLM
Can read and extract information from supplied documents.
n8n + LLM
Can do this with configured workflows and AI.
Extraflow
Identifies orders and extracts information from emails and documents.
If your team receives orders through emails/whatsapp, PDFs, Excel files, or images, this comparison explains what each approach can do, what you'll need to build yourself, and when a dedicated solution like Extraflow makes more sense.
TL;DR: Which Option Should You Choose?
Choose n8n/zapier if…
You have technical resources, need flexible integrations, and want to build and maintain your own automation. It can automate the full process, provided you build the business logic around it.
Choose Extraflow if…
You need to turn customer orders into ERP records, match products against your catalogue and customer-specific prices, and business rules - including requested delivery dates, lead times, and order requirements - while giving your team full control over exceptions and approvals.
The bottom line: All three can help you process an email. The real question is how much of the operational system you want to build and maintain yourself.
From customer email to ERP order: What does each option actually handle?
Reading an order is only the first step. Here's what happens when the customer uses different product names, negotiated prices, or unexpected document formats.
- Read incoming orders
- Find the correct products and prices
- Let your team check and correct orders
- Get orders into your ERP
- Keep everything running
| What needs to happen | n8n + LLM | Standalone LLM | |
|---|---|---|---|
| 1. Read incoming orders | Identifies orders and extracts information from emails and documents. | Can do this with configured workflows and AI. | Can read and extract information from supplied documents. |
| 2. Find the correct products and prices | Matches customer descriptions with ERP products, order history, and agreed prices. | You need to build and maintain the matching logic. | Needs access to your catalogue, customer records, and business rules. |
| 3. Let your team check and correct orders | Staff review exceptions and correct orders in a dedicated interface. | Approvals are possible; a complete order-review interface requires additional work. | Requires a separate application for team review. |
| 4. Get orders into your ERP | Designed to work with existing cloud and on-premise ERP systems. | Possible through connectors and custom integration. | Needs external tools and integration to create orders. |
| 5. Keep everything running | Order tracking, corrections, and ongoing product maintenance. | Your team maintains workflows, business rules, and custom components. | Requires an operational system around the model. |
Your customers don't speak ERP. Extraflow understands both.
Your customers use their own product names and descriptions. Your ERP expects exact product codes, quantities, and agreed prices.
Extraflow connects the two.

Where the Differences Actually Matter
For the first two steps -identifying an order and extracting its details—the approaches can produce similar results.
The difference becomes meaningful when extracted text must become a valid ERP transaction.
This is the problem Extraflow is built to solve.
See How Matching WorksProduct Matching Is Where the Real Work Begins
Customers don't always use your product names. Extraflow uses more than the words in the email to identify the correct order.
The more your team corrects, the less repetitive work it needs to do.
Your Catalogue
Find the right product.
Identify ERP items even when customers use different names, abbreviations, or descriptions.
Your Business History
Find the right customer and price.
Use order history and customer-specific pricing to narrow down possible matches.
Your Team's Corrections
Improve future matching.
Use previous corrections so repeated customer terminology becomes easier to process.
Building the First Automation Is Easy. Maintaining It Is the Hard Part.
The Weekend
The demo works.
Connect an inbox, extract order information, and send it to another system.
The First Month
Real-world exceptions appear.
Different document formats, customer prices, product names, and ERP rules need handling.
The First Year
Someone needs to own everything.
New customers, changed products, integration updates, and ongoing troubleshooting.
Build vs Buy: What's Included in the Work?
| What you need | DIY with n8n / Zapier | |
|---|---|---|
| Product matching | Dedicated capability | Build and maintain |
| Order-review interface | Included | Configure or build |
| ERP integration | Implementation required | Connector setup/custom development |
| Maintenance | Dedicated product team | Your team or partner |
The real cost isn't just the software subscription. It's the time, development, maintenance, and manual intervention needed to process a correct order.
