CASE STUDY
POS System with Margin Intelligence
Pricing clarity at the point of sale, with margin always visible.
- Pricing logic
- Decision flow
- Operations
Overview
A POS workflow designed around margin visibility and pricing guardrails—so sales decisions stay aligned with the business model, even under speed and pressure.
Problem
Margin was effectively hidden. Staff could discount without seeing the real trade-off, pricing rules lived in people’s heads, and profitability drifted without a clear source of truth.
Approach
Treat pricing as an operational system. Encode the rules, expose the trade-offs, and design the UI around the moment decisions are made—not around admin settings.
System design
- Margin-first line items: every cart decision surfaces profit impact, not just revenue.
- Discount guardrails: constrain discounting to approved ranges, with explicit reasoning when exceptions are needed.
- Role-based controls: separate who can set rules from who can apply them during checkout.
- Pricing inputs normalized: unify cost, tax, and discount logic so calculations behave consistently across products.
Key insight
Pricing errors are rarely “math problems.” They’re decision problems. The system has to make the right decision the easiest decision.
Impact
- Reduced discount drift by making margin impact visible during checkout.
- More consistent pricing behavior across staff, without extra training overhead.
- Clearer conversations between sales and ops because the rules became explicit and inspectable.
