Profit-first Amazon seller software
Amazon seller software that shows what to scale, cap, hold or stop before you spend more.
CEILR turns product economics, Amazon PPC, keyword, cash and inventory evidence into one seller-reviewed decision. See the CPC your ASIN can afford, whether cash and inventory support more traffic, and the evidence behind the next action.
CEILR is published in the Amazon Selling Partner Appstore, supports seller-authorized Amazon connections, and remains read-only to Amazon seller state. CEILR does not create or change listings, prices, inventory, orders, bids, budgets or keywords.
The seller problem
Amazon sellers rarely lack metrics. They lack a single defensible decision across conflicting metrics.
A keyword tool can say demand is attractive. A PPC dashboard can say ACoS is rising. A profit dashboard can say the ASIN is still profitable. Inventory can say only 24 selling days remain. Cash can say the next purchase order is due before the next settlement. Those are not six unrelated facts. They are one operating decision.
| Signal | Dashboard-only interpretation | CEILR decision question |
|---|---|---|
| High search demand | “Target the keyword.” | Is it relevant, economically supportable and evidenced strongly enough to pursue? |
| ACoS = 28% | “Good” or “bad” versus a generic benchmark. | What is this ASIN's allowable ACoS after actual landed cost, fees and desired retained contribution? |
| CPC = US$1.20 | Compare with category/auction CPC. | Can the product afford US$1.20 at the observed conversion rate? |
| Campaign is profitable | Scale spend. | Can available cash and inventory fund the additional click/order volume? |
| Rank improved | Optimization worked. | Did visibility improve after a recorded action, and did the resulting traffic create a better economic outcome? |
| Data is missing | Fill the blank with an estimate. | Keep the field missing and lower confidence until supported evidence exists. |
Core decision layers
CEILR connects the parts of an Amazon business that normally live in separate tools.
The platform is intentionally category-agnostic. The formulas use the seller's product economics and evidence rather than a generic “good Amazon margin” or “good ACoS” benchmark.
01Product and competitor evidence
Research becomes an input, not a verdict.
Product and competitor evidence
Research becomes an input, not a verdict.Use supported product and competitor evidence to investigate opportunities, competing ASINs and visibility. CEILR does not present unsupported competitor sales, ranks or demand estimates as facts. See Amazon product research and reverse ASIN research.
02Keyword intelligence
Relevance → evidence → listing/PPC decision.
Keyword intelligence
Relevance → evidence → listing/PPC decision.Keyword evidence is reconciled with listing coverage, visibility state and PPC economics. A high-volume term is not automatically a good term if it is irrelevant, already covered or financially unsafe. See Amazon keyword research.
03Profit-Safe CPC
How much can a click cost while protecting contribution?
Profit-Safe CPC
How much can a click cost while protecting contribution?CEILR calculates the allowable advertising amount from selling price, landed cost, Amazon/per-order fees, other variable costs and the contribution you choose to preserve. Conversion rate translates that per-order advertising room into a CPC ceiling. Test it with the Amazon CPC calculator.
04Fundable CPC
Profitability is not the same as affordability.
Fundable CPC
Profitability is not the same as affordability.A campaign may be profitable on paper while consuming more operating cash than the seller can safely deploy before settlement, reorder or other commitments. Fundable CPC adds the capital constraint. See Profit-Safe vs Fundable CPC.
05Inventory continuity
Do not scale demand blindly into a stockout.
Inventory continuity
Do not scale demand blindly into a stockout.Runway, reorder economics and inventory evidence sit beside PPC decisions so a seller can see when additional demand conflicts with replenishment timing or cash. See Amazon inventory planning.
06Evidence Health and Decision Memory
Know why the decision exists and what happened after it.
Evidence Health and Decision Memory
Know why the decision exists and what happened after it.CEILR records evidence source, freshness and decision history instead of treating all numbers as equally trustworthy. Missing or stale evidence can reduce confidence. Later measurements can be attached to the original decision rather than reconstructed from memory.
Worked Amazon PPC economics
“What should I bid?” starts with unit economics, not the auction suggestion.
This worked example is hypothetical and exists to show the arithmetic. It is not Amazon market data or a recommended bid.
| Input / result | Value | Formula |
|---|---|---|
| Selling price | US$44.95 | Seller-entered |
| Landed cost | US$18.00 | Seller-entered |
| Amazon / fulfilment fees | US$8.50 | Seller-entered verified amount |
| Other variable cost | US$1.00 | Seller-entered |
| Pre-ad contribution | US$17.45 | 44.95 − 18.00 − 8.50 − 1.00 |
| Break-even ACoS | 38.82% | 17.45 ÷ 44.95 |
| Observed conversion rate | 10% | Seller-entered evidence |
| Break-even CPC | US$1.75 | 17.45 × 10% |
| Protected contribution | US$5.00/order | Seller objective |
| Profit-Safe CPC | US$1.25 | (17.45 − 5.00) × 10% |
| Available ad cash | US$1,000 for 1,200 planned clicks | Fundable CPC = US$0.83 |
| Final operating ceiling | US$0.83 | Lower of 1.25 Profit-Safe and 0.83 Fundable |
With these inputs, US$1.10 CPC is below break-even, but it is still above both the seller's cash-funded operating ceiling and the final decision ceiling. “Below break-even” is not the same as “safe to scale.”
Amazon PPC software
CEILR is deliberately decision support, not an autonomous ad operator.
Some Amazon sellers want software to change campaigns automatically. CEILR is not built for that operating model.

Amazon seller software comparison
Where CEILR is stronger—and where established competitors remain stronger.
CEILR should not be bought because a marketing page claims it replaces every specialist tool.
| Need | Consider | Why |
|---|---|---|
| Largest mature product/keyword research ecosystems | Helium 10 / Jungle Scout | Longer data history, specialist workflows and established research scale. |
| Automated Amazon advertising execution | Helium 10 / specialist PPC automation | CEILR remains read-only by design. |
| Detailed profit dashboard/accounting workflow | sellerboard and similar specialists | Mature dedicated profit/cost reporting can be deeper than CEILR's decision layer. |
| Profit + PPC + cash + inventory in one decision | CEILR | This cross-functional financial boundary is CEILR's core product thesis. |
| Evidence provenance and missing-data discipline | CEILR | Source quality, freshness and missing evidence are explicit decision inputs. |

Who CEILR is for
Best fit: sellers with real products, real PPC and real capital constraints.
CEILR is most differentiated after the seller has moved beyond “should I open an Amazon account?” and is managing decisions across live products.
01Private-label and brand operators
Contribution and inventory matter.

Contribution and inventory matter.When a seller has product-specific landed costs, referral/fulfilment fees, advertising spend and reorder commitments, generic benchmarks become less useful than product-specific economic ceilings.

One decision chain.If the same keyword appears separately in research, PPC, rank and profit tools, CEILR's value is carrying the signal across those domains until one decision is economically and evidentially coherent.
