Calculates break-even ROAS, PNO/COS and target ROAS per category and campaign mix from contribution margin (COGS, fees, fulfilment, returns), on the same VAT and shipping basis as your Google Ads conversion value, with all arithmetic shown.

Plans SKU-level clearance markdowns from stock, sell rate and exit date, stops at a VAT-correct floor, and shows the EU Omnibus 30-day prior price and correctly based discount percentage for every step, including progressive-markdown rules.

Compares your offers with competitor prices you supply, matched on GTIN and on total price with shipping, flags where you are out of the market or leaving margin, and suggests the smallest price move above your VAT-correct floor.

Lets an agent read and write iDoklad through API v3 for an online store: unpaid and overdue invoices, payments backed by bank records, Default-template drafts the owner approves, credit notes and accountant exports.

Lets an agent work a store's Stripe account safely via the Stripe plugin, MCP or REST: find payments, explain declines, triage disputes by due date, reconcile payouts and fees, and prepare owner-approved refunds.

Sets or reviews a free-shipping threshold and shipping prices from your own basket distribution, carrier cost per parcel, contribution margin and bunching below the line, with profit per order and a test readout, no invented lift.

Decides before launch whether a sale, coupon or bundle pays: break-even uplift from contribution margin, pull-forward, cannibalisation, coupon leakage, ad-target impact, EU 30-day prior price check and a baseline readout.
