Profitability · F-2
You think your ROAS is healthy. Once you layer COGS, a different story emerges.
Trellis applies your COGS to each attributed order and ranks every campaign by what it actually contributes from a margin perspective, not by what it looks like in isolation. Some "top-performing" campaigns may land below break-even once your margin lands. You'll know exactly which ones.

Platforms claim credit for orders. Your first-party data surfaces what actually happened.
Ad platforms may conflate clicks, views, and page visits as a primary conversion metric. Your store records what was actually purchased. Trellis reconciles every platform claim against your first-party order data and surfaces the duplicates, view-throughs, and visits platforms wrongly counted as sales. You'll know which sales were real.

Changelog · F-5
Your Changelog gives the next audit evidence to recommend what's working in your accounts.
Keep a record of the changes you make (budgets, campaigns, ad groups, and keywords) using our Changelog templates. During your next audit, the Changelog will evaluate which adjustments improved performance and which ones resulted in wasted spend. By your sixth audit, the confidence core has compounded against six cycles of recorded outcomes — the range tightens to your account's actual responsiveness, so recommendations are calibrated to how you convert, not to a generic benchmark.

Understand the why behind your campaign's results.
The Trellis Rating reads each connected ad account and rolls them into one profit-weighted number. Not a vanity metric. It surfaces your contribution margin (revenue derived from campaigns less ad spend and COGS), shows you the weakest signal from your account, and recommends what changes to make.

4 audits covering 30 of 30 days
Each recommendation passes five independent gates before it surfaces. Miss any threshold and the audit holds the finding for monitoring. You see what's worth watching, not what's forced from thin data.
- Statistical weight: enough conversions that the pattern isn't random.
- Audit depth: enough history to compare against your own baseline, not someone else's.
- Business context: your gross margin, your AOV, and attribution-validated orders.
- Falsifiable structure: each recommendation names a credible alternative and the threshold that would shift the call.
- Evidence traceability: every figure traces back to a value computed from your data, not a number a model invented.
When the evidence is weak, the audit holds the finding for monitoring instead of pushing a recommendation. A held finding is a valid result, not a failure. When the evidence is strong, the recommendation shows its work: the recommended direction, a credible alternative, and the threshold that would shift the call in the next audit.
The Changelog stitches each audit to the next, anchored by every change you record on the ad platforms. After three audits, the model projects budget impact. After six, it runs full inference calibrated to how your account responds. The hours you used to spend combing reports and joining CSVs stay reclaimed.
A full audit written for your account, not a generic template.
Every audit applies your gross margin, cross-references your order data, and gates every recommendation behind a statistically significant conversion floor. The methodology is the rigor.
Whether you're running ads yourself or owning the channel inside a small business, Trellis calibrates depth, focus, and recommendations to your business economics. One methodology, adapted to how you work.

Your first Catalyst Audit
Ready when you are.
Connect your accounts and your first Catalyst Audit runs in minutes. Every recommendation is grounded in your first-party data and your real business economics.
Questions worth asking.
The Trellis confidence core grades every recommendation, not a generic AI prompt. Each one is gated by a conversion threshold: below it, the audit holds the finding for monitoring instead of forcing a recommendation. Above it, the audit names a credible alternative and the threshold that would shift the call in the next audit. Every claim carries an evidence tag traceable back to your data.
Trellis connects to your ad platforms via OAuth: the same authorization Google, Microsoft, and Meta use. The connection is read-only. Trellis pulls performance data for analysis but never modifies bids, budgets, or campaign settings on your account. Your business economics (margins, targets, COGS) are encrypted at rest and isolated per workspace. No data is shared between clients.
Three things your ad platform’s reporting won’t surface: whether campaigns are profitable after your COGS (not just on revenue), whether platform-reported conversions match the orders your store actually recorded, and which configuration changes caused performance shifts. A campaign showing 3× ROAS may be operating near break-even once your gross margin lands. Trellis catches that; the platform UI does not.
Connect your ad platforms via OAuth in under two minutes. Enter your blended gross margin: one number. Run your first audit. Most accounts see their first scored report within minutes of signing up. No CSV uploads, no technical configuration. The first report tells you how your campaigns are really doing.
Owner-operators, in-house marketers, and agencies running multiple client accounts. The methodology scales to any of them. The same evidence standards and confidence gating apply whether you’re running one campaign or fifty.
Each Catalyst Audit reads your Changelog of the changes you’ve recorded on the ad platforms since the last audit, then measures their actual effect on margin and conversion. After three audits, the model projects budget impact. After six, it runs full inference calibrated to how your account responds. Each audit gets more specific over time.
