Short answer: you don't need a new ERP. Most ERPs can already import orders from a file or through an API. What's missing is the step in between, where someone reads each customer PO and types it in. You can close that gap four ways: move buyers to an ordering portal, use a self-serve document parser, buy an order automation platform, or have a custom AI order desk set up around your ERP. In every option, a person should approve orders before they post.
Why orders still get retyped
Large customers often send orders by EDI, which flows straight into the ERP. Everyone else sends what they have: a PDF attached to an email, a spreadsheet, a few lines typed in the email body, sometimes a scan. Each one has its own layout, and customers use their own part numbers. So someone opens the email, finds the part in your system, checks the price, and keys the order line by line. The ERP isn't the problem. The problem is that nothing reads the PO for you.
The four ways to fix it
| Option | How it works | Your effort | Pricing model | Best fit |
|---|---|---|---|---|
| Ordering portal | Buyers place orders themselves on a website tied to your catalog and pricing | Medium. Customers must agree to use it | Monthly subscription | Repeat customers who are willing to change how they order |
| Self-serve document parser | A tool pulls fields out of emailed POs. You build the rules and the link to your ERP | High. You set up and maintain templates | Low monthly plans | Low volume and someone on staff who likes setting up tools |
| Order automation platform | Software built for sales order entry reads POs and pushes orders to supported ERPs | Medium. Vendor-led setup | Annual contract, quoted | Higher volume and an ERP the vendor already supports |
| Custom AI order desk | AI reads POs, matches them to your parts and prices, and builds the order in your ERP's import format. Someone sets it up and runs it for you | Low | Setup plus monthly, quoted | Smaller shops that want it done for them, or ERPs the platforms don't cover |
What the workflow looks like
Whichever option you pick, a good setup follows the same five steps:
- The PO arrives in a shared orders inbox.
- The order details are read: customer, ship-to, dates, and every line.
- Each line is matched to your part number and price, including customer part numbers that differ from yours.
- Anything that doesn't match is flagged for a person.
- A person approves, and the order goes into the ERP.
Step 5 matters. Automation that posts orders with nobody looking is how a wrong price ships.
What to have ready
- An export of your part list or item master from the ERP
- Your current price lists, including customer-specific prices
- A list of customer part numbers that differ from yours, if you have one. If you don't, the first few weeks of orders will build it.
- How your ERP takes orders in: a file import, an API, or neither
- A few months of real POs from your top customers, to test with
How to choose
If most of your orders come from a few customers who would use a portal, start there. If you process a high volume of orders on an ERP a platform already supports, get quotes from order automation platforms. If you're a smaller shop, your ERP is less common, or you want someone else to set it up and keep it running, a custom setup is usually the better fit. Marson Labs builds the custom option, so weigh that when you read this. The checklist above applies whichever way you go.
Questions
Do I need to replace my ERP to automate order entry?
No. If your ERP can import orders from a file or connect through an API, it can take automated orders. Most can do at least one.
Will customers have to change how they send orders?
Not with document-based options. They keep emailing POs. Portals are the only option that asks customers to change.
What happens when a PO is messy or a part number doesn't match?
In a good setup, that line is flagged and a person fixes it before the order posts. Nothing should go into the ERP unreviewed.
