Amazon profitability software

Amazon profitability software should answer more than “did revenue go up?”

CEILR connects unit contribution, advertising economics, cash support, inventory continuity and evidence so sellers can distinguish profitable growth from growth that only looks healthy in a revenue dashboard.

Profit truth before growth

Separate sales, contribution, ad efficiency and fundability.

A product can grow revenue while contribution falls, ACoS looks acceptable while cash tightens, or PPC scales just before inventory becomes constrained. CEILR keeps those trade-offs visible.

01

Pre-ad contribution

What remains before advertising.

Start from selling price minus landed cost, Amazon/per-order fees and other per-order costs. This is the economic room advertising has to work with.

02

Protected contribution

Decide what profit must survive.

A break-even advertising ceiling is not always the right operating ceiling. CEILR can preserve a seller-entered contribution target before determining ad room.

03

Profit-Safe CPC

The economic click ceiling.

Translate allowable ad spend per order through conversion rate to determine the maximum CPC supported by the entered unit economics.

04

Fundable CPC

The cash-aware ceiling.

A click can be profitable in theory and still be unsafe to fund. CEILR keeps the economic ceiling distinct from the cash-supported ceiling.

05

Inventory continuity

Profit is irrelevant if stock disappears.

Growth recommendations must respect stock runway, supplier lead time, inbound units and reorder needs rather than optimizing PPC in isolation.

06

Evidence health

Know which numbers deserve confidence.

Provider estimates, seller-entered costs and observed marketplace evidence have different trust states. CEILR keeps freshness and missing-data status attached.

Profit decision stack

The minimum stack for a financially rational growth decision.

CEILR evaluates economic room first, then fundability and continuity.

CEILR does not guarantee profit and does not silently fill missing cost, conversion, cash or inventory inputs. Seller economics remain seller-controlled.
