The short version
Trello (Atlassian) offers simple, visual kanban boards with cards, lists, and power-ups. It's great for lightweight tracking.
Prime RP is an operational ERP: weighted projects, multi-step approvals, finance, procurement, and field ops, with native chat and video.
Simple boards vs an operating system
Trello is perfect until work needs structure: dependencies, weighted progress, approvals with audit, budgets, and offline field capture. Prime RP provides that structure out of the box rather than bolting it onto cards.
Side-by-side
| Dimension | Trello | Prime RP |
|---|---|---|
| Simple kanban | Best-in-class | Built-in |
| Weighted progress & WBS | No | Yes |
| Multi-step approvals + audit | No | Yes |
| Finance & procurement | No | Yes |
| Built-in chat & video | No | Yes |
Bottom line
Trello wins for simple, delightful boards. Prime RP wins when work needs operational structure and communication.
