I’m pretty certain AI quadruples my output at least and facilitates fixing, improving and upgrading poor quality inherited software much better than in the past. Why pay for SaaS when you can build something “good enough” in a week or two? You also get exactly what you want rather than some £300k per year CRM that will double or treble in price and never quite be what you wanted.
Building is only one part. Maintaining and using/running is another.
Onboarding for both technical and functional teams takes longer as the ERP is different from other company. Feature creep is an issue. After all who can say no to more bespoke features. Maybe roll CRM, Reporting and Analytics into one. Maintenance costs and priorities now become more important.
We have also explored AI agents in this area. People specific tasks are great use cases. Create mock up and wireframes? AI can do well and you still have human in the loop. Enterprise level tasks like say book closing for late company ERP? AI makes lot of mistakes.
