POS as an Execution Layer, Not a SaaS App
A POS is not a workflow tool or a reporting dashboard. It is the live execution layer of your business.
2 min de lecture
Most POS platforms are built as SaaS products.
This is where the problem starts.
SaaS assumes:
- ✕ Time to think
- ✕ Time to reload
- ✕ Time to wait
- ✕ Connectivity
Retail execution has:
- ✓ Customers waiting
- ✓ Pressure to perform
- ✓ Zero tolerance for delays
- ✓ Real-world constraints
POS is not a system of record

The POS
Executes — live, under pressure
Execution cannot depend on SaaS assumptions
When a POS is treated like a SaaS app:
- • Workflows become rigid
- • Custom logic becomes expensive or impossible
- • Staff adapts to the system instead of the system adapting to operations
Execution slows down. Errors increase.
The execution-layer model
A true execution-layer POS:
- ✓ Integrates with ERP and CRM without replacing them
- ✓ Owns real-time operational logic
- ✓ Works independently at store level
- ✓ Centralizes rules while allowing local variation
This is not a UX decision. It is an architectural one.
Key takeaway
If your POS behaves like a SaaS dashboard, it will eventually fail under real operational pressure.
