Manufacturing ERP Software: How to Prepare Before Vendors Start Pitching
Not All ERPs Are Built the Same
The acronym “ERP” covers more ground than people assume. Deltek and Certinia are built around projects, time, and billing for professional services firms and never touch a bill of materials or a work order, because their customers don’t have one. Other systems are core financial and CRM platforms where manufacturing gets bolted on later rather than being the reason the system exists. Then there’s a third category built manufacturing first, Epicor, Infor CloudSuite Industrial, and Plex among them, where production is the whole point and everything else supports it. Odoo leans toward that third group once you turn on the Manufacturing app, but it started as a flexible core platform you build outward from, which is part of why it stretches across different types of shops instead of locking you into one.
Discrete vs. Process vs. Job Shop
Discrete manufacturing builds distinct, countable units, machined parts, assemblies, equipment, and leans on bills of materials and work orders. Process manufacturing runs batches or continuous production, food, chemicals, and similar industries, and leans more on formulas and lot tracking. Job shops are their own category entirely, built around custom, one-off work quoted job by job, where accurate job costing matters more than repeatable routings. These three run differently enough that your ERP decision often comes down to which one actually describes you. JobBoss was built specifically for job shops, and NetSuite handles discrete work well but has real, documented gaps in tying a finished lot back to the component lots that went into it, which matters if you’re process manufacturing under compliance requirements. Odoo covers all three reasonably well without forcing you into one lane, worth knowing if you don’t fit neatly into just one.
There’s No Universal “Best”
Anyone claiming a single best manufacturing ERP for every business is selling something. Complexity here isn’t just headcount, it’s how many distinct steps your product passes through before it ships. An assembly shop putting together purchased components at one work center is a simpler problem than a shop running fabrication, then assembly, then paint, then QA as four separate stations, each feeding the next. The more work centers in that chain, the more the ERP has to track work in process moving between them. The right answer depends on your size, your industry, and your budget, a system built for a 500-person plant is often the wrong fit for a 15-person job shop, and vice versa. Locations matter too, a single facility can get by with a simpler setup than a business running two or three plants that need to share inventory or roll up numbers at month end. The real question isn’t which system is best, it’s which one fits the size and complexity you’re actually running at right now, and whether it can grow with you for the next ten years without forcing another migration down the road.
See More Than One Vendor Before You Decide
This is a decision you’ll likely live with for the better part of a decade, worth seeing more than one system before you commit to it. The problem is a generic vendor demo tells you almost nothing, every business has its own quirks, and a salesperson walking you through their best canned workflow isn’t the same as watching the system handle your actual process. Below is a script built around what you told us about your operation, the specific things worth putting in front of every vendor you talk to, so you’re running the same test across three or four demos instead of judging each one on how polished the presentation was. It’s a solid starting point, but it’s high level by design. Once you get into the real distinguishing requirements specific to your shop, that’s usually where it helps to have someone who’s done this before in the room, which is where we come in.
P.S. if you found this useful, there are ten more like it on the free tools page.
Get Vendors To Run YOUR Demo, Not Theirs
Left alone, most vendors will run you through the same polished demo they give everyone else, built to show off their strengths and steer around their weak spots. Answer six questions about how you build, and you’ll get a list built around your distinguishing requirements, the specific things to hand every vendor so they’re demoing your operation instead of their sales deck.
