PromoMate reads your Shopify orders to help you judge a sale before, during and after it runs. Before: it estimates how much extra sales your discount needs to break even, from your own trading history. During: it watches the sale's pace against that target. After: it reports what the sale did, updating as refunds and later orders settle, and carries what it learned into your next sale. It gives evidence-based estimates, not predictions or advice.

• See what your discount needs to earn before the sale starts
• Watch the sale's pace against that target while it runs
• Get an honest result afterwards, updated as refunds settle
• Carry what each sale taught you into the next one
