Is ERP Worth the Cost? A Complete Guide to ERP ROI

When you’re shopping for ERP software and see the price tag, it’s natural to wonder, "Is this really worth it?" If you’ve come across ERP quotes that feel higher than expected, you're not alone. Many small to mid-size businesses find themselves in this situation when considering an ERP implementation.

Here's what we’ve found through decades of working in the ERP space: Budget becomes a big hurdle when the value isn’t clear.We also know that ERP isn’t just another software purchase. It’s a long-term investment in how your business runs. And when it’s the right fit, the return can be transformational.

How to calculate the ROI of ERP

Let’s start with this formula:

ROI = (Value of investment – cost of investment) / Cost of investment * 100%

To get a realistic number, you’ll want to look at both your Total Cost of Ownership (TCO) and the measurable benefits. Here’s how that breaks down.

Total cost of ownership

• Software licenses or subscriptions
• Implementation services
• Training and onboarding
• Custom development or integrations
• Ongoing support and maintenance

Measurable benefits

ERP systems deliver savings across three key areas:

1. Displaceable costs

• Lower inventory costs: Better inventory management leads to reduced carrying costs, fewer expedited shipments, and increased inventory turns.
• Reduced labour costs: Automation minimizes manual tasks, allowing your team to focus on higher-value work. For example, one ProjectLine customer eliminated the need to hire an extra full-time role after ERP implementation.
• Reduced days sales outstanding: With integrated quote-to-cash processes, you can speed up invoicing and improve cash flow. One client reduced invoicing time from three months to two weeks.

2. Avoidable costs

• Avoid leasing additional warehouse space by improving inventory turnover.
• Prevent headcount increases or reduce costly overtime through process efficiency.

3. Intangible benefits

• Better decision-making with more reliable data
• Enhanced customer relationships via faster service
• Stronger vendor negotiation resulting in better pricing
• Fewer costly errors and smoother handoffs between departments

You won't be able to catch every benefit in a spreadsheet, but these should help you build a strong case for the value of your ERP investment.

How to improve your ROI from ERP

Getting a great return doesnt mean spending more. It means:

• Choosing the right-fit system (not just the biggest name)
• Standardizing processes before you implement
• Starting with core features, customizing later
• Training your team well from day one
• Working with an experienced  ERP partner who can guide you through the best practices and help you avoid common pitfalls

Consider total value, not just the upfront cost

If you're experiencing sticker shock, you're not alone. The price tag of ERP can feel daunting, especially when you don't have a clear picture of what you’re getting in return. But once you see the full scope of benefits—from tangible cost savings to business transformation—the investment starts to make a lot more sense.
