The ERP pitch sounds great. The reality doesn’t.
Someone told you that your shop needs ERP. Maybe it was a software sales rep. Maybe it was a consultant. Maybe it was an article that said “every growing manufacturer needs ERP.” The pitch goes like this: one system for everything. Quoting, scheduling, inventory, purchasing, accounting, quality, shipping. All connected. All automated.
It sounds like the answer to every problem your shop has. So you look into it.
Then you see the price: $49 per user per month (MRPeasy’s starting rate, for example). For 8 people, that’s $392/month. The enterprise tier with the features you actually need is $99/user. Now it’s $792/month. Tools like Katana aren’t much better, starting at $299/month. Plus implementation fees. Plus training. Plus a consultant to configure the system because the setup isn’t something you do in an afternoon.
You haven’t even started using it yet and you’re $5,000 in.
This is where most small manufacturers either walk away or sign up and regret it. Both reactions make sense. The software is good. It’s just not built for you. I cover this in more detail in why ERP for small manufacturers doesn’t make sense.
What ERP is built for
ERP stands for Enterprise Resource Planning. The key word is “enterprise.”
ERP systems were designed for companies with hundreds of employees, multiple departments, and complex supply chains. A company that needs purchasing to talk to manufacturing to talk to accounting to talk to shipping. A company with a full-time IT team to configure, maintain, and troubleshoot the system.
When you have 200 employees across 5 departments, a unified system makes sense. The purchasing manager creates a PO. The receiving team marks it as received. The inventory updates. The accounting system records the expense. The production schedule adjusts. Everything flows.
But you don’t have 200 employees. You might have 8. You don’t have 5 departments. You might have 2. You don’t have a full-time IT team. You have yourself.
The problem isn’t that ERP is bad. The problem is that ERP solves problems you don’t have, at a cost you can’t justify, with a complexity you can’t maintain.
What goes wrong when small shops try ERP
I see the same pattern repeat.
The setup never finishes
ERP systems require configuration. Bills of materials. Cost centers. Workflow rules. User permissions across 15 modules. Routing templates. Quality checkpoints. Purchasing approval chains.
For a large company, a consultant spends weeks configuring this. For a small shop, the owner spends evenings and weekends trying to figure it out between running jobs.
In our experience, most small shops configure 20% of the system and leave the rest untouched. They never finish setup because the setup is designed for a team of people, not one person with three other jobs.
The team doesn’t adopt it
You set up the system. You learned how to use it. But your floor workers didn’t. The interface has 30 menu items and they need 3. They can’t find the schedule because it’s buried under modules they’ve never heard of.
So they don’t use it. They go back to asking you. The system you spent weeks configuring becomes a tool for one person. That’s a $400/month personal organizer.
You use 10% of the features
ERP systems have modules for quoting, purchasing, inventory management, production planning, quality control, shipping, accounting integration, CRM, document management, and more. Small shops use: scheduling, basic inventory, and maybe job tracking.
You’re paying for 40 features and using 4. The other 36 aren’t free. They clutter the interface, complicate the setup, and slow everything down. Every module is another thing to learn, configure, and maintain.
The cost keeps growing
Per-user pricing means every new hire increases your software bill. Brought on a part-time machinist? That’s another $49/month. Hired a helper for the summer? Another seat. Want your shop foreman to check the schedule on his phone? Another seat.
The bill grows with your team, even though the value of the software hasn’t changed. You’re still scheduling the same machines. I break this down further in per-user pricing is killing small manufacturers.
What small manufacturers actually need
I’ve talked to a lot of shop owners. When you strip away the software marketing and the ERP hype, what they need comes down to four things.
1. Machines
You need to know what every machine is doing. Is the CNC running or idle? What job is on the lathe? Whether you run a machine shop or an assembly operation, this is the core question. When does the current job finish? Is the oven available tomorrow morning?
This is the core of running a shop floor. If you can’t answer these questions without walking over to each machine, you’re running blind.
2. People
You need to know who’s working on what. Which operator is on the CNC? Who’s available for the next job? Is anyone double-assigned?
In a 5-person shop, this fits in your head. In a 10-person shop with two shifts, it doesn’t. You need a place to assign operators to jobs and see who’s where.
3. Materials
You need to know what you have in stock. Do you have enough aluminum bar for the next three jobs? Are you low on grinding wheels? Will you run out of packing material before the end of the week?
You don’t need a full procurement system with purchase orders, vendor management, and receiving workflows. You need a number that tells you what’s on the shelf and a warning when it gets low.
4. Schedules
You need to see your entire shop on one screen. Every machine, every job, every deadline. A visual scheduling board that shows what’s running, what’s next, and where the conflicts are.
That’s it. Four things. Machines, people, materials, schedules.
If a tool covers those four things well, it covers what most small shops need. The other features that ERP systems offer (quoting, accounting, CRM, purchasing, quality management) are either handled by other tools you already use or aren’t needed at your scale.
Why less is more for small shops
There’s a reason “simple” keeps coming up when shop owners describe what they want.
Simple means everyone uses it. If the tool takes 10 minutes to learn, your whole team will use it. If it takes a week of training, only you and maybe one other person will use it. Full adoption is the difference between a tool that works and a tool that sits unused.
Simple means fast setup. You want to be scheduling today, not configuring a system for two weeks. Import your machines, add your jobs, start scheduling. If you can’t be up and running in an afternoon, the tool is too complex for your shop.
Simple means fewer things break. A tool with 4 features has 4 things that can go wrong. A tool with 40 features has 40 things that can go wrong. And when something breaks in an ERP, you need a consultant to fix it. When something breaks in a focused tool, you send a support email.
Simple means affordable. A tool that does 4 things costs less to build, maintain, and support than a tool that does 40. That’s why focused scheduling tools cost $10 to $40/month while ERPs cost $200+/month.
What about the other stuff?
“But I also need quoting.” Keep using whatever you use now. If it’s a spreadsheet, that’s fine. Quoting is a different workflow from scheduling.
“But I also need accounting.” You already have QuickBooks or Xero or your accountant’s system. Your scheduling tool doesn’t need to do accounting.
“But I need it all in one system.” Do you? Or has someone told you that you should? Most 5-to-15 person shops run on 3 to 4 tools: scheduling, accounting, email, and maybe a spreadsheet for quoting. That’s fine. Those tools don’t need to be connected. The connections add complexity without adding value at your scale.
The “everything in one system” pitch works for a 200-person company. For an 8-person shop, it means paying for and maintaining 30 features to get the 4 you need.
How to figure out what you need
Here’s a quick exercise. Takes 5 minutes.
Write down every question you answer about your shop floor in a typical day.
- “What’s running on the CNC?”
- “When is the Johnson job due?”
- “Do we have enough 1018 bar?”
- “Who’s on the lathe this afternoon?”
- “Is the saw free tomorrow?”
Now look at your list. How many of those questions are about machines, people, materials, or schedules? For most shops, the answer is all of them.
That’s what you need software for. Not quoting. Not accounting. Not CRM. The shop floor.
If you have questions that don’t fit those four categories, write those down too. That tells you what other tools you might need. But start with the floor. That’s where the pain is.

Frequently asked questions
Do small manufacturers need ERP software?
Most don’t. ERP systems are built for large operations with dedicated IT staff. Small manufacturers with 3 to 30 machines typically need production scheduling, not a 40-module system they’ll use 10% of.
What software do small manufacturers actually need?
A production scheduling tool that covers four things: machines, people, materials, and schedules. Everything else can stay in the tools you already use.
Why do small manufacturers struggle with ERP?
Three reasons: too complex to set up without consultants, too expensive with per-user pricing, and too broad. They include 30+ modules when most shops use 3 to 4. The result is expensive software that nobody fully adopts.
What’s the difference between ERP and production scheduling?
ERP covers everything: quoting, purchasing, accounting, inventory, HR, quality, and more. Production scheduling focuses on putting the right jobs on the right machines at the right time. Most small shops need scheduling, not ERP.
Start with what matters
You don’t need 40 features. You need 4. Machines, people, materials, schedules. If a tool covers those well, it covers what your shop needs today.
You can always add more tools later. If you grow to the point where you need full MRP, purchasing automation, or quality management, those tools will still be there. But you don’t need to buy them before you need them.
Start with the shop floor. That’s where the work happens. That’s where the problems are. Fix that first, and the rest takes care of itself. If you’re ready to look at tools, here’s my guide to production scheduling software for small manufacturers.
