Amazon profitability software
Amazon profitability software that turns profit into the next seller decision.
See what remains after landed cost, Amazon fees and advertising, then connect that contribution to CPC, cash and inventory before you scale. CEILR keeps the financial boundary visible instead of treating revenue growth as the decision.

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.
01Pre-ad contribution
What remains before advertising.
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.
02Protected contribution
Decide what profit must survive.
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.
03Profit-Safe CPC
The economic click ceiling.
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.
04Fundable CPC
The cash-aware ceiling.
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.
05Inventory continuity
Profit is irrelevant if stock disappears.
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.
06Evidence health
Know which numbers deserve confidence.
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.
| Question | Signal | CEILR decision |
|---|---|---|
| Unit contribution | Price − landed cost − fees − other costs | Know the pre-ad room |
| Allowable ad spend | Contribution − protected contribution | Set the ad room per order |
| Profit-Safe CPC | Allowable ad spend × CVR | Set the economic CPC ceiling |
| Fundable CPC | Cash-supported CPC vs Profit-Safe CPC | Use the lower ceiling when cash is constrained |
| Inventory guardrail | Runway + lead time + inbound | Avoid profitable demand that creates a stockout |
CEILR does not guarantee profit and does not silently fill missing cost, conversion, cash or inventory inputs. Seller economics remain seller-controlled.
