Custom business application vs ERP: which one to choose?

Yahya Samadi20 February 20248 min read

A client running a bicycle rental business in Casablanca called me one day with a direct question: 'Yahya, someone's offering me Odoo at 800 dirhams per user per month. Does that make sense for us?' His company had 12 employees, two branches, and very specific booking and tracking processes tied to his business. I told him no — and here's why.

Honestly, we think Odoo and SAP are oversized for 80% of Moroccan SMEs. They're not bad products — they're just built for organizations with dedicated IT teams, standardized processes, and a serious training budget. An SME with 15 to 100 people and workflows specific to their industry isn't their natural target.

Market ERPs shine where processes are standard: accounting, payroll, ISO-style invoicing. But the moment you have specific business logic — fleet management, real-time construction tracking, reservations with dynamic availability — you end up customizing the ERP. And that's where costs explode: consultants, configuration, training, add-on modules.

A custom application costs more upfront — that's fair to say. But it's built exactly around your processes, takes two to three weeks to master (versus three to six months for an ERP), and doesn't charge you per-user licenses. For the bicycle client, we built a solution in eight weeks covering reservations, per-branch bike tracking, and automatic contract generation. He now saves over four hours a day in manual data entry.

The only case where we'd recommend an ERP: when the SME genuinely needs full, certified accounting and financial coverage, and has someone internal to run it. In every other case, an application targeting the real operational problems will be more effective and cheaper over three years.

What's your main bottleneck today — invoicing, field tracking, stock management? That answer should drive your choice, not the other way around.
