The best ERP for manufacturing is the one that matches how you make things: a light MRP system if you're a small maker moving off spreadsheets, a full manufacturing ERP for job shops and engineered products, or a modular suite you grow into. Below are ten options in no particular order, with whether each offers a free plan or only a trial.
Manufacturing software tends to get chosen in the finance office and then handed to the shop floor, and that's where most rollouts wobble. The people who build the product, book the materials and chase late jobs are the ones who'll live in the system every day, so their questions matter as much as the accountant's.
This list covers ten ERP and MRP systems sorted alphabetically and in no particular order. I've taken every description from the maker's own website, re-checked today, and I've kept the free column honest: most of these are sold through a demo or a trial, and only a couple have a free option you can keep using. If you're planning the wider rollout too, my piece on planning an ERP implementation step by step is a good companion.
Manufacturing ERP systems at a glance
Free plan means the maker's site describes something you can keep using with no time limit, such as open-source software or a one-app plan. Trial only means a time-limited trial. No means the route in is a demo or a conversation with sales.

The NIST rule that follows defence and federal work
If you supply US federal agencies, or a defence prime that does, this one matters before you sign anything. NIST publishes SP 800-171 Revision 3, which replaced Revision 2, and it sets out recommended security requirements for protecting Controlled Unclassified Information in nonfederal systems. It covers the components that process, store or transmit that information.
What that means for a manufacturer: drawings, specifications and order details from a government contract can count as that kind of information, and your ERP is where they'll end up. Ask each vendor, in writing, how their system supports those requirements and where your data is held. If you don't do government work, it's still a sensible security checklist to borrow.
MRP, full ERP or a modular suite?
- Cloud MRP: bills of materials, production orders and stock in one place. Often the quickest win for a small maker on spreadsheets.
- Manufacturing ERP: adds job costing, quoting, shop floor control and accounts. Suits job shops and engineered products.
- Modular suite: start with one or two apps and add more. Flexible, but someone has to own how the pieces fit.
- Open source: free software you can run yourself. You'll need a person or partner who's comfortable looking after a server.
Steps for running a manufacturing ERP trial
- List your five most painful jobs, such as late orders or stock you can't find, before you look at any demo.
- Pick one real product with a full bill of materials and use it in every trial, so you're comparing like with like.
- Get a shop floor lead and someone from accounts into each trial, not just the person signing off.
- Check how the system handles your routing, scrap and part-finished work, not just the finished goods.
- Ask how your data comes back out if you leave, and in what format.
- Only book the long implementation once a short pilot has worked.
Training is where good systems succeed or stall, and my guide to training staff on a new ERP covers how to get people using it from week one.

My plain advice for manufacturers replacing spreadsheets
If you're a small maker and your problem is stock and production orders, start with a cloud MRP trial and see if it covers you before you look at a full ERP. If you're a job shop that quotes custom work, put job costing at the top of your list, because that's where spreadsheets lose you the most.
Whatever you choose, run the trial with a real product and the people who'll use it. And if you touch any government or defence work, ask the security question first, not after go-live.
Frequently asked questions
What is the difference between MRP and ERP?
MRP plans materials and production. ERP usually adds accounts, sales, purchasing and more, so the whole business runs from one system.
Is there a free ERP for manufacturing?
Yes, a couple. Some are open-source software you host yourself, and some offer a free plan with one app. Check what's included before you commit time to setting one up.
How long does a manufacturing ERP take to set up?
It depends on how many products, routings and users you have. A small maker can often get going on a cloud MRP quickly, while a full ERP for a larger plant takes far longer.
Do I need an ERP if I only have a few staff?
Not always. If stock and production orders are the pain, a lighter MRP may be enough. Move up when accounts, sales and purchasing start fighting each other.
What should I ask in an ERP demo?
Ask to see your own product built in the system, how it handles scrap and rework, how stock is counted, and how you'd export your data if you left.
Does NIST SP 800-171 apply to my business?
It's aimed at nonfederal organisations handling Controlled Unclassified Information, usually through US federal or defence contracts. If you're not sure, ask your customer what they require.
