Amazon PPC guardrails
Amazon PPC software that shows the maximum CPC your product can afford.
Before you raise bids or budgets, CEILR compares represented current CPC with Profit-Safe CPC, Fundable CPC, cash and inventory evidence so you can see whether the next click is economically supportable.

The decision card
Three numbers before one decision.
CEILR does not invent missing inputs. If current CPC, economics, cash or inventory evidence is absent, the decision stays evidence-bounded instead of being filled with a generic recommendation.
| Signal | What CEILR uses it for | Truth boundary |
|---|---|---|
| Profit-Safe CPC | Your economic click ceiling from represented contribution and conversion. | Profitability ceiling, not a promise of future conversion. |
| Fundable CPC | The lower cash-supported ceiling when represented liquidity and commitments make the profitable ceiling unaffordable. | Left unavailable when the required cash inputs are missing. |
| Current CPC | Compared with the represented ceilings before CEILR promotes more spend. | Must come from connected/imported seller evidence; missing stays missing. |
| Decision | Seller-reviewed scale, cap, hold or evidence-needed guidance with the binding reason visible. | CEILR never sends the bid or budget change to Amazon. |
Fast first value
Start with the Amazon Search Term Report you already have.
You do not need to replace your existing research stack. Import seller-owned performance evidence, add the product economics CEILR needs, and review which terms are inside the represented ceiling, over it, or still need evidence.
Import the Search Term Report.CEILR validates the required performance columns instead of silently converting missing metrics to zero.
Add real product economics.Selling price, landed cost, Amazon/per-order fees, protected contribution and the represented conversion inputs drive the ceiling.
Compare spend with the guardrail.See where represented CPC is within the supported ceiling, above it, or cannot yet be judged because evidence is incomplete.
Keep the reason attached.The decision retains its evidence, constraint and later proof path instead of disappearing after the recommendation.
Apply the packet in Seller Central.CEILR stays read-only. Execution Proof records recommended, tracked, verified, drifted or inconclusive from readable Amazon targeting state.
Grade later settled evidence.A later Search Term Report that starts after the tracked date can support WRONG or not-falsified. Missing later evidence stays ungraded.
Already use Helium 10, Jungle Scout or sellerboard? Keep the specialist data you trust. CEILR's job starts where the next financial decision still needs to be reconciled.
Why ACoS alone is not enough
A profitable click and a fundable click are two different questions.
Profit-Safe CPC asks whether the unit economics support the click.It is tied to represented contribution and conversion, not a category benchmark.
Fundable CPC asks whether the business can safely fund the planned traffic.Cash commitments and represented constraints can make this lower than the profitable ceiling.
Track the decision afterwards.CEILR preserves the reasoning and later evidence so the seller can grade what happened instead of remembering only the wins.
If the represented evidence cannot support a scale decision, CEILR is designed to say so rather than manufacture certainty.

The point is not to add another PPC dashboard. It is to stop the next advertising dollar from being judged on ACoS alone.
