Tools of Moltline Dropship Economics
	Description		Read-only	Idempotent	Open world
`lead_time`Turn supplier and transit times into a date you can promise. FREE. Adds a buffer, because the number a supplier quotes is their best case and the date you publish is a commitment. Typical input {"supplier_days": 3, "transit_days": 12, "order_date": "2026-08-20"} returns {"total_days": 17, "delivery_date": "2026-09-06", "promise_date": "2026-09-09", "advice": "..."}. Use when writing a shipping policy or answering "when will it arrive". Not for what the shipping costs: that is the shipping server. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "order_date must be YYYY-MM-DD, e.g. 2026-08-20"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.	Turn supplier and transit times into a date you can promise. FREE.

Every call is read-only and idempotent, so after correcting the input it is always safe to retry.	No	Yes	Yes	No
`margin_check`Show what one sale actually leaves after every cost. FREE. Subtracts supplier cost, shipping, payment fees, the ad spend that found the buyer, and anything else, then reports the break-even price so you know how much room there is. Typical input {"sell_price": 39.99, "supplier_cost": 12.4, "shipping_cost": 4.2, "ad_cost_per_order": 9} returns {"revenue": 39.99, "total_cost": 27.06, "profit": 12.93, "margin_pct": 32.33, "markup_pct": 222.5, "break_even_price": 27.06, "biggest_cost": "supplier_cost"}. Use before listing a product. Not for a whole tiered price list (that is price_ladder) and not for the effect of returns, which is returns_impact. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"}.

`moq_planner`Decide how much to order against demand, lead time and the cash you have. PREMIUM (license). A minimum order quantity is a cash-flow decision disguised as a purchasing one. Typical input {"unit_cost": 4.2, "moq": 500, "monthly_demand": 120, "cash_available": 3000, "lead_time_days": 45} returns {"moq_cost": 2100.0, "months_of_cover": 4.17, "affordable": true, "cash_after": 900.0, "reorder_point_units": 236, "verdict": "..."}. Use before committing to a supplier's minimum. Not for the margin each unit earns: that is margin_check. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"}.

`price_ladder`Work backwards from the margin you want to the price you must charge. FREE. Solves for price including the percentage fee, which is why it is not simply cost divided by one minus margin. Typical input {"supplier_cost": 12.4, "target_margins_pct": [30, 40, 50], "shipping_cost": 4.2} returns {"rows": [{"target_margin_pct": 30, "price": 25.99, "total_cost": 17.65, "profit": 8.34, "actual_margin_pct": 32.07}, ...]}. Use when setting a price list. Not for checking one price you already have: that is margin_check. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "target_margins_pct must contain at least one margin"}).

Every call is read-only and idempotent, so after correcting the input it is always safe to retry.	No	Yes	Yes	No
`returns_impact`Show what a return rate does to a margin that looked fine. PREMIUM (license). A 10% return rate does not cost 10% of profit. A returned order gives back the refund, adds inbound shipping, and recovers only the goods, never the advertising that found the buyer. Typical input {"sell_price": 39.99, "unit_profit": 13.23, "unit_cost": 12.4, "return_rate_pct": 8, "restock_pct": 70, "return_shipping": 6} returns {"cost_per_return": 37.31, "effective_profit": 10.25, "profit_lost_pct": 22.56, "break_even_return_rate_pct": 35.46}. Use when a category's returns are high enough to argue about. Not for the pre-returns margin itself: that is margin_check.

`sku_map_check`Find the breaks in a supplier-to-store SKU map before they ship. FREE. Two store SKUs pointing at one supplier SKU is usually intentional; two supplier SKUs claiming one store SKU is not, and it sends the wrong item. Typical input {"mapping": {"STORE-1": "SUP-A", "STORE-2": "SUP-A", "STORE-3": ""}} returns {"ok": false, "count": 3, "empty_targets": ["STORE-3"], "shared_supplier_skus": {"SUP-A": ["STORE-1", "STORE-2"]}, "whitespace_issues": []}. Use before importing a mapping or handing one to a fulfilment app. Not for validating Shopify's CSV columns: that is the shopify server. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "mapping must contain at least one store SKU"}).
