The term MRP gets thrown around a lot in manufacturing circles — but what does it actually do? This plain-English guide breaks it down for business owners, not IT managers.
If you've ever Googled "MRP software" and come away more confused than when you started, you're not alone. The term gets thrown around a lot in manufacturing circles, but the plain-English explanation is often hard to find. This guide is written for business owners — not IT managers — who want to understand what MRP actually does and whether it might be right for their operation.
MRP stands for Material Requirements Planning. At its core, MRP software is designed to answer three questions that every manufacturer deals with every day: What do I need to make? When do I need to make it? And what materials and resources do I need to do it?
A modern MRP system ties together your production schedule, your bills of materials (BOMs), your inventory levels, and your supplier lead times — and uses all of that to help you plan production runs, manage stock, and place purchase orders at the right time.
The result is less guesswork, fewer stock-outs, less overbuying, and a clearer picture of what's happening on your shop floor at any given time.
Spreadsheets are genuinely useful — most manufacturers start with them for a reason. They're flexible, cheap, and fast to set up. But as your product range grows, your team expands, and your production complexity increases, spreadsheets start to fight against you rather than for you.
The core problem is that spreadsheets are static. Every time stock moves, a production run starts, or a new order comes in, someone has to manually update a file — and hope everyone else is looking at the same version. MRP software handles all of this automatically, in real time, for everyone on your team simultaneously.
If you've experienced stock discrepancies, missed reorders, or production delays caused by a spreadsheet that didn't get updated, you've already felt the gap.
Accounting software like Xero, MYOB, or QuickBooks is built to track your financial transactions — invoices, payroll, GST, BAS. It does that job very well. But it's not designed to manage your production operations.
Think of it this way: accounting software tells you how much money you made. MRP software helps you make things more efficiently so there's more money to account for.
The two systems are complementary. Most MRP platforms will integrate with your existing accounting software so financial data flows between them automatically — no double entry required.
MRP software is most valuable for businesses that manufacture or assemble physical products — anything from food and beverages to industrial equipment, furniture, clothing, or custom fabrication.
If you're a small service business or a simple retailer without a production floor, MRP software is probably overkill. But if you make things, and that making is becoming hard to manage, it's worth exploring.
At MRPsupport, we specialise in two platforms: MRPeasy, which is purpose-built for manufacturers and distributors, and ERPNext, which is a broader open-source ERP that suits businesses needing more than just production management. Both are cloud-based, both are priced for SMEs, and both are significantly more capable than they appear at first glance.
See a full breakdown of both platforms and what's included in each implementation:

Modern MRP platforms like MRPeasy are far simpler to implement than the enterprise ERP horror stories from 10 years ago. Most SME implementations are live within 4–8 weeks.
The first step is usually a free discovery call to map out your current process and figure out whether an MRP platform would genuinely help — and which one fits your business. There's no obligation and no sales pressure. Just an honest conversation.

Both MRPeasy and Cin7 are well-regarded platforms for Australian SMEs. But they're built for meaningfully different use cases — and choosing the wrong one is an expensive mistake.
