Short answer: Conexiom is built for sales order automation and fits higher-volume manufacturers and distributors on ERPs it supports. Rossum is a broad AI document platform with a published entry plan of about $18,000 a year. Parseur is a low-cost, do-it-yourself parser. A custom AI order desk is set up and run for you around the ERP you already have. For most shops under 150 people, the deciding questions are order volume, which ERP you run, and whether anyone on staff will maintain the setup.

Conexiom
Conexiom focuses on one job: turning customer POs into clean sales orders. It reads PDFs, spreadsheets and emails, checks them against your ERP data, and sends the order in. It lists integrations with more than 40 ERPs and has especially deep ties to Epicor's distribution systems. Its customers include large distributors like Fastenal and Graybar.
Good fit if: you handle a high volume of orders and run an ERP on its list.
Think about: pricing is quoted and aimed at larger operations.
Rossum
Rossum is an AI platform for reading business documents of many kinds, not only purchase orders. It's strong when you have several document types to automate at once. Its entry plan has been listed at about $18,000 a year, with higher plans quoted.
Good fit if: you want one platform for orders, invoices and other documents.
Think about: connecting it to your ERP is part of the setup, so plan who will do that work.
Parseur
Parseur pulls data out of emails and attachments. It's inexpensive and quick to start. You build the parsing rules and connect the output to your ERP yourself, usually with an automation tool.
Good fit if: you have low volume, simple PO layouts, and someone who enjoys setting up tools.
Think about: every new customer layout, part-number mismatch and ERP change becomes your job to maintain.
A custom AI order desk
This is the approach Marson Labs takes. AI reads each PO, matches lines to your parts and prices, flags anything off, and builds the order in your ERP's own import format. Your team approves before anything posts. It's set up for the ERP you already have and kept running for you.
Good fit if: you're a 20 to 150 person shop, you want it done for you, or your ERP isn't on the big platforms' lists.
Think about: it's a service relationship, so pick a builder you trust to stay responsive.
Five questions to decide
- How many orders a month arrive by email, PDF or spreadsheet?
- Which ERP do you run, and can it import orders from a file or an API?
- Who on your team would maintain the setup?
- Do you need other documents automated too, like invoices?
- What would one wrong order cost you, and who should approve orders?
Questions
Is Conexiom worth it for a small manufacturer?
It can be at higher order volumes on an ERP it supports. Pricing is quoted, so get a quote with your real monthly order count.
Can I automate PO entry for less than an enterprise platform costs?
Yes. Self-serve parsers start on free or low monthly plans, and custom setups are quoted to your size. The trade-off is who does the setup and upkeep.
Do any of these replace my ERP?
No. All four feed orders into the ERP you already run.
