TrueMargin calculates your store's net profit by subtracting cost of goods sold, payment-processing fees, shipping, and ad spend from your Shopify sales. A profit waterfall shows where the money goes, and a per-product breakdown shows which products make money. When a product's cost is missing, TrueMargin estimates it and labels it as an estimate that you can accept or edit. An optional daily email summarizes yesterday's net profit and margin.

• Net profit after COGS, payment fees, shipping, and ad spend
• AI estimates missing product costs, clearly labeled and editable
• Per-product margins that reconcile to your shop total
• A daily profit email with yesterday's net profit and margin

Cleartill calculates your store's profit after tracked costs by subtracting cost of goods sold, payment-processing fees, shipping, and ad spend from your Shopify sales. Overheads such as rent and salaries are not tracked, and the app says so. A waterfall shows where the money goes, and a per-product breakdown shows which products make money. Missing product costs are estimated and clearly labeled, and you can edit them. An optional daily email summarizes yesterday's profit and margin.

• Profit after tracked costs: COGS, payment fees, shipping, ad spend
• AI estimates missing product costs, clearly labeled and editable
• Per-product margins that reconcile to your shop total
• A daily profit email with yesterday's profit and margin

Days of Cover tells you which products to reorder, when, and how many units to buy. It ranks by profit rather than sales volume, because your biggest seller is not always the one worth your money. Give it a budget and it funds your most urgent products first, then says what it could not fund. Once a month it estimates what stockouts cost you. Every suggestion expands to its arithmetic. It is read-only: marking a purchase order received here does not change your Shopify inventory.

• Daily reorder list ranked by urgency or by profit at risk
• Purchase orders that fit a budget, with a report of what went unfunded
• Last month's estimated lost profit from stockouts, by product
• Every suggestion expands to the arithmetic behind it
• Import your Stocky export: suppliers, lead times and stock history
