Executable, not theoretical
Only actionable spreads
Every opportunity pairs a buy-side retailer you can actually source from with a sell channel where you can list third-party inventory. No dead-end price gaps you can't execute.
DecimalShiftOpportunity Network
LiveRetail-arbitrage opportunity intelligence
Actionable arbitrage edges across 28+ marketplaces.
DecimalShift scans pricing in real time and surfaces only the spreads you can actually execute — buy from a sourceable retailer, sell on a marketplace that takes third-party inventory, with margin modeled after fees and shipping.

What surfaces, and why it's real
28+ marketplaces · real-time
Continuous sweeps
DecimalShift runs live scans across 28+ retailers and marketplaces, re-checking pricing as it moves so the edge in front of you reflects the market right now.
Profit, not price gap
Margin after fees
Cost modeling folds in marketplace fees and shipping before anything surfaces, so the projected profit is the number you'd actually keep — not a raw price delta.
Confidence you can trust
Twin-SKU matching
Cross-store matching confirms the buy and sell legs are the same product before a spread is shown, suppressing the look-alike mismatches that turn a 'deal' into a loss.
