RP pricing talk tends to focus only on the software cost. It skips the parts that actually set your total spend. Here's the full picture.
Off-the-shelf ERP: lower upfront cost, ongoing licensing¶
Standard ERP platforms usually charge a per-user, per-month fee. This can look cheap at first. But it grows with your team size. A 5-user setup and a 50-user setup do not cost the same over time. You're also stuck with the platform's set modules and logic. That's fine if your work is fairly standard: accounts, basic stock, a standard sales line.
Custom ERP development: higher upfront cost, no per-user licensing trap¶
A custom-built ERP is shaped around your real workflow, not the other way around. You own it outright. There's no fee per seat that grows as your team does. This costs more to build at first. But some firms have needs that don't fit a mold. Think set approval chains, rules tied to your trade, or odd stock logic. For them, this often costs less over 2 to 3 years. That beats fees on a stock platform that still needs constant patchwork.
The costs a lot of ERP quotes leave out¶
- Data moves. Moving your old records, like customers, stock, and past deals, into a new system takes real work. It's often quoted on its own, or not quoted at all until it's too late.
- Training. A system your team doesn't know how to use isn't saving you a thing. Budget time and cost for real hands-on training, not just a short guide.
- Custom creep. Off-the-shelf ERPs that need heavy custom work to fit your process can end up costing close to a custom build. It's just spread across "small" change requests over a year.
- Connecting to what you have now: your website, your accounting software, your CRM. An ERP that doesn't talk to your other systems just becomes one more place to enter the same data.
How to decide¶
If your core work, like accounts, standard stock, and standard sales tracking, is truly plain, off-the-shelf is usually the faster, cheaper start. Maybe you keep spreadsheets now to patch gaps in a stock tool. Or your process is set enough that no stock tool can flex to fit it. Either one is a sign that custom development pays for itself.
