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

Shared Excel spreadsheets sent by email, double entry between accounting and stock, figures that never match at the end of the month: one day, every growing company asks itself about real management software. And the next question follows immediately: buy an existing product or have one custom-built?

01What an off-the-shelf product brings

Ready-made software (ERP, CRM, point of sale or payroll software) was designed for thousands of companies. Its strengths:

• Quick start: the product already exists.
• Proven features for standard processes.
• An often lower upfront cost.

Its limits appear when your way of working does not match the intended model: your teams work around the tool, the Excel files come back, and you pay licences for features nobody uses. Also check support for French and Arabic, for Algerian regulations and taxation, and for local payment methods.

02When custom software becomes the right choice

Custom software is built around your processes, not the other way round. It makes sense in particular when:

• your way of working is your competitive advantage (logistics, production, a particular customer relationship);
• you need to connect several tools that do not talk to each other;
• you want to control your data and the code, without depending on a vendor;
• existing products force you to pay for many modules to use only a small part of them.

Good software does not ask your teams to change jobs: it removes what slows them down.

03The hybrid option, often the most cost-effective

The choice is not binary. Many companies keep an off-the-shelf tool for accounting or payroll, and have custom-built what sets them apart: a sales dashboard, a field app for sales reps, a portal for resellers. The two worlds are connected through APIs.

04Five questions to decide

1. 01
   Are our processes standard or specific to our business?
2. 02
   How many different tools do we use today, and do they talk to each other?
3. 03
   What happens if the vendor changes its prices or discontinues the product?
4. 04
   Who needs to use the tool, on which devices, and in which languages?
5. 05
   What is the real cost over several years, including licences, training and adaptations?

05How a custom project works

At Codex, a custom software project starts with a scoping workshop to understand your business, then mock-ups approved screen by screen before development. Deliveries are made in phases, with a demo every time: you see the software take shape, and you can adjust priorities along the way.
