Should we go with custom software or off-the-shelf software for our order management?

Over the years, I've seen very few SMEs build custom software and not end up regretting it. Unless your business model is a tech product itself, don't reinvent the wheel. Off-the-shelf platforms are refined by the collective experience of thousands of companies; standardizing your approval flows around those best practices will make your business far more structured in the long run.

With bespoke builds, source code ownership, documentation quality, and library maintenance are always massive question marks. Most agencies leave zero documentation. If you part ways with them two years later, no other developer will want to touch that code—they'll just tell you to scrap it and rewrite everything from scratch.

Back in 2021, we paid 19.000 € for custom software for a similar wholesale business. By the end of year two, between change requests, server costs, and bug fixes, total spending hit 34.000 €. If we’d gone with an off-the-shelf cloud solution, we would have paid 11.000 € at most over three years.

Take these three steps right now: 1) Map out your current order workflow step by step into a diagram. 2) Figure out which of your discount approval rules are genuinely essential and which are just force of habit. 3) Test run the trial versions of the two most popular off-the-shelf software options for 14 days with a few real orders.

edit: I wrote something wrong above, sorry about that.

Off-the-shelf systems aren't completely innocent either. You start with a per-user licensing model, and then the moment you hit an extra user or data storage limit, your annual bill suddenly doubles. Plus, your data is held hostage in their cloud, leaving you to deal with incomplete CSV files when you try to export it.

we had custom software built then the dev kid moved back to his hometown and the whole system blew up in our faces... they wanted money for every tiny button change we switched to an off-the-shelf system and its been pure peace of mind dont go looking for trouble imo

Will your B2B customers place orders through their own customer portals or will the software only be used internally by the 14 people on your team? If you're planning a customer-facing B2B portal, off-the-shelf B2B e-commerce modules run way more stably on these budgets.

The general consensus in this thread is clear: a 28.000 € initial investment plus 450 € in monthly maintenance is an unnecessary risk for your revenue and order volume. Adapting your processes to off-the-shelf software is far cheaper and safer than taking on the maintenance and developer dependency risks of custom software.

Here's how it went for us. Start with a small trial; don't commit to everything at once.

If I were you, I'd go this route.

I'd say don't rush. The biggest time-waster for us was not knowing who had the final say.

Im also curious if anyone does it differently.

The cheap-looking path usually ends up costing more later. Taking notes for two weeks yields better results than a six-month estimate.

If you post the result here, it will help others too.

Thanks, that was the answer I was looking for.

You're right.

Correct. The biggest time-waster for us was not knowing who had the final say.

The answer varies greatly by industry; there is no one-size-fits-all rule.

Thanks for writing this that's the right way. If scope grows either time or budget must grow. There is no third option.

Proven by experience.

Correct.

I feel the same way. If it's your first time, start small; scaling comes later.

If I were you, I'd go this route.

i was thinking the same thing. the biggest time-waster for us was not knowing who had the final say.
