The revenue side of the profit tree
Installed inside the Shopify admin, Seamline reads your store on a schedule: orders, payments, refunds, fulfilments and the SKU list.
What is read
- Paid, partially paid and refunded orders with their line items
- Payment transactions with settlement currency and fees
- Refunds and refund line items
- Fulfilment records and the SKU catalogue
Where it lands
- Order totals, discounts, taxes and shipping lines form the revenue side of each SKU row
- Transaction fees feed the platform fee check when Shopify Payments is the gateway
- Refund amounts drive the refund-rate and return-fee checks
- SKU identity is what links ad spend and cost profiles back to profit
Rules fed by store data
Seven active rules read on these records. Each finding names the affected orders and the evidence behind it.

- FX gain/loss spike
- Daily FX gain/loss rate jumps above the 7-day baseline and an absolute threshold
- Order-vs-gateway reconciliation gap

- Refund loss-rate spike
- Refund loss rate per SKU or country jumps vs the 7-day baseline
- Return fee surge
- Return fees multiply vs the 7-day daily average
- SKU contribution margin drop
