Price Safety System (Price Gateway)

Every price change in Repricefy goes through a 3-layer safety system before it reaches Amazon. Even if there's a bug in a strategy, the Price Gateway catches it.

Layer 1: Strategy + Floor/Ceiling Check

The repricing strategy calculates a target price, then it's checked against your floor and ceiling:

  • Target below floor? → Uses floor instead
  • Target above ceiling? → Uses ceiling instead
  • Target within bounds? → Proceeds to Layer 2

Layer 2: Safety Guardrails

Even if the price is within floor/ceiling, additional safety checks run:

Maximum change per cycle: 30%

If the price would change by more than 30% in a single cycle, it's blocked. This prevents sudden crashes from bad data.

Example:

  • Current price: $35.00
  • Strategy wants: $22.00
  • Change: 37% → BLOCKED
  • Result: price stays at $35.00

The next cycle, the strategy will try again. If competitors really did drop that much, the price will step down gradually over multiple cycles.

Layer 3: Price Gateway (Final Validation)

This is the last line of defense before any price reaches Amazon:

  1. Recalculates your floor price FRESH — uses current supplier cost, current fees, current margin settings
  2. Blocks losses — if the final price would result in a negative margin, it's blocked
  3. Auto-corrects — if your current Amazon price is already below your floor (from a manual change or data error), the Gateway raises it to the floor
The Price Gateway is unique to Repricefy. Most repricers rely only on floor/ceiling checks. Our 3-layer system catches edge cases that simple floor/ceiling checks miss — like when your supplier cost changed since the floor was last calculated.

What gets blocked?

The Price Gateway blocks:

  • Any price below your current floor (recalculated fresh)
  • Any price that would result in negative profit
  • Any change greater than 30% in a single cycle
  • Any price that seems like an error (e.g., $0.01 on a product that normally sells for $30)

What happens when a price is blocked?

  1. The price stays unchanged on Amazon
  2. A log entry is created explaining why it was blocked
  3. You can see all blocked prices in your Repricing Log
  4. The strategy tries again on the next cycle

Can I override the safety system?

No. The Price Gateway cannot be disabled. It exists to protect you from selling at a loss, even if you make a configuration mistake.

Your Ninja Foodi Pressure Cooker:

  1. Strategy (Buy Box Targeting): target price = $87.99
  2. Floor/Ceiling: $85.00 floor, $120.00 ceiling → $87.99 is within bounds ✓
  3. Safety guardrails: current price was $89.99, change is 2.2% → under 30% ✓
  4. Price Gateway: recalculates floor from current supplier cost ($67.50) → floor = $84.20 → $87.99 > $84.20 ✓
  5. Result: $87.99 sent to Amazon ✓
