Every discount needs more sales just to stand still. Evenline shows exactly how many, from your real Shopify cost per item, fees, shipping and refunds. Compare price changes, % off, free shipping, free-shipping thresholds and multi-buy offers. Plan a fair test with sample size and run time from your traffic, then review the result from any testing tool and log a decision you can defend. Evenline never changes your prices.

• Break-even lift for price changes, discounts, free shipping and multi-buy offers
• Uses your Shopify cost per item and order-history refund rate
• Sample size and run time from your own traffic and costs
• Review results from any testing tool against your break-even line
• Versioned costs and a locked decision log, in English or Chinese
