Custom software or off-the-shelf: how to choose?

The strengths of off-the-shelf software

Standard software is available right away, its cost is shared across many customers and it often has a large user community. For common needs, it is usually the most sensible option.

You simply have to accept working the way the software intends, and depend on the vendor for new features and pricing.

Signs it is time to go custom

Custom software becomes worthwhile when off-the-shelf software costs more than it brings:

• you work around the software with spreadsheets or double entry
• you pay for several subscriptions that do not talk to each other
• your products, units or processes do not fit the mold
• an essential feature does not exist and will not come
• you want to offer a unique service your competitors do not have

What custom software brings

Software built for you follows your exact workflow, connects to your existing tools (POS, store, accounting) and evolves with your business. You own the tool and your data.

In return, it requires an upfront investment and ongoing care. That is why it should be reserved for cases where it brings a real gain.

The middle path: connect rather than replace

You do not always need to rebuild everything. Often the best effort-to-gain ratio is to keep off-the-shelf software and build around it: a connector between two tools, an automatic import script, a dashboard that combines data. Languages like Python or Go are perfect for these small, high-impact programs.

Questions to ask before deciding

Before starting development, take time to answer a few simple questions:

• how much time do we lose each week with the current tool?
• which mistakes keep coming back?
• which tools need to talk to each other?
• who will use the software, on what device, and how comfortable are they?
