A Profit number is only as good as the Costs under it. Kompound keeps every Cost effective-dated and never overwrites one — so a price change on the 1st moves your Margin from the 1st, and last quarter stays as it was.

Kompound models each one the way it actually behaves, not as a single flat percentage.
Pull cost from Shopify, enter your own, import a spreadsheet, or start with a Default Margin. Every entry is dated, and a coverage summary shows how much is still an estimate.
A packing fee per Order and a picking fee per item, dated — the two costs most brands forget and most tools cannot hold.
Carrier cost from what the Customer paid or from your own rate card, by weight, quantity or destination. Duties per country.
A percentage of the full capture plus a flat fee, per gateway, exactly as Shopify Payments, PayPal or Stripe charge it. Refund fees included.
Software, agencies, rent — recurring or one-off, categorised, imported from a spreadsheet or straight from your Shopify bill.
Salaries and hourly contractors with dated pay changes, classified as COGS, Marketing or Operating so the Margin Ladder stays right.
Refund Basis, how refunded goods are costed, and your Default Margin — the three settings that decide what “Profit” means for your Store.
Keep test Orders, wholesale and staff purchases out of your financial Reports by tag, payment status, Channel or value.
Ask “which Cost rose most this month?” and get the Income Statement, filtered to that line.
Costs are where Profit quietly disappears. Ask which one moved, and Kompass checks all eight.
How Ask Kompass Works →Set a Default Margin and start. The Income Statement is honest from that moment, and the footnote always tells you how much of COGS is still the estimate.
Nothing. Costs are effective-dated — a new figure applies from the date you give it, and history keeps the figure that was true at the time.
Yes, by spreadsheet for Products and Operating Expenses, and directly from your Shopify bill for app subscriptions.
Your choice in Accounting Settings: returned to inventory, or written off. It changes COGS, so the setting is stated on the Report.
Product cost, fulfillment, fees, ads and payroll — entered once, applied from the day they changed.
