Verified AI Cost & Unit-Economics Report — synth-01
Period reconciled: 2026-06-01 to 2026-07-01 · Prepared for: synth-01
This report is an evidence pack of reconciled and verified AI-cost data — deterministic software output computed on company-provided inputs, prepared for and addressed to synth-01. It reflects reconciled historical data for the period 2026-06-01 to 2026-07-01: analysis of a closed, backward-looking window, not a forecast. [ Sample — in a delivered report, the client-specific legal framework appears here. Wording under counsel review. ] Full restricted-use and limitation-of-liability terms appear at the end of this report.
How to read this report
Two vocabularies recur below; read them once here.
Verification tiers — how firmly each dollar is established:
- T1 Reconciled — recomputed for each request and tied to the provider invoice; the firmest tier.
- T2 Invoice-verified — confirmed against invoice totals but not per request (for example, fixed subscription pools).
- T3 Management-declared — asserted by the company and not independently confirmed here.
- Uncovered — spend seen but not placeable in a tier; disclosed, never presented as declared.
Reconciliation quantities — how the invoice ties out:
- Coverage — the share of the invoice reconciled per request (the T1 share).
- Residual — the reconciliation error on tracked spend; near zero means tracked dollars tie to the invoice to the cent.
- Untracked — invoice spend the telemetry did not capture. Untracked is not a residual: a near-zero residual does not mean full coverage.
Inputs register and company assertion
[T1 RECONCILED] sources · [T3 MANAGEMENT-DECLARED] assertion. [EV-08]
Reconciliation draws on 3016 reconciled records (hashed for integrity) and effective-dated price tables. The company assertion (click-wrap) is captured in-product at delivery; in this synthetic demo it is a placeholder.
AI cost reconciles to the provider invoice to the cent; margin level warrants attention and vendor concentration warrants attention.
Reconciled AI cost of $9,716.21 ties to the provider invoice: $9,181.07 of tracked spend reconciles per request — the 94.49% coverage figure — while $283.14 (2.91%) is untracked spend the telemetry did not cover; the residual on tracked spend is $0.00 (cent-exact — a distinct quantity from untracked, not the same gap). Recoverable waste is estimated at $4,322.57/mo; the achievable-efficiency ratio (AER) — how close current spend already runs to the cost-optimal baseline — is 85.6%. Figures below carry a verification-tier badge. Each dimension measures a distinct thing — see the column — so a red margin and a green attribution score are not in conflict. [EV-01, EV-07]
Assessment (benchmark-relative index, never an absolute figure):
[T1 RECONCILED]
| Dimension | What it measures | Index | Status | Input tier |
|---|---|---|---|---|
| Margin Level (vs benchmark) | Where the AI-loaded gross margin sits today against public anchors — a current-level read, not a stress test; a higher margin is healthier | 15.8 | red — warrants attention | T1 cost + T3 revenue |
| Margin Resilience (under stress) | How much of the AI-loaded gross margin survives the worst replayed adverse shock — a price increase or caching disabled — a self-referential fragility test with no external benchmark; a thin surviving margin means the business absorbs cost shocks poorly | 24.5 | red — warrants attention | T1 cost + T3 revenue |
| Vendor Concentration | How exposed spend is to one provider — the inverse of the largest provider's cost share | 17.3 | red — warrants attention | T1 |
| Cost Efficiency (share optimized) | What share of spend already runs at the cost-optimal achievable baseline (AER) — a high value means most spend is optimized and only a small slice is recoverable, not that efficiency is mediocre | 85.6 | amber — warrants review | T1 |
| Unit-Economics Quality (current) | How completely current cost is attributed to a feature or tenant (chargeback-readiness) — a data-quality signal about today's tagging, not the margin itself; lightly penalised if any cohort runs at a loss | 80.9 | green — healthy | T1 |
The method is deterministic reconciliation, not estimation
Per-request token counts are recomputed against effective-dated provider price tables and tied to the provider invoice total (F2). Zero LLM in the cost path. Verification tiers: T1 RECONCILED (per-request, tied to invoice), T2 INVOICE-VERIFIED (invoice totals), T3 MANAGEMENT-DECLARED (company-asserted), UNCOVERED (seen but not placeable — never folded into T3). Reconciliation tolerance is 2.0%. [EV-08]
Every reconciled dollar ties to the invoice, to the cent
The signature exhibit. [EV-01]
[T1 RECONCILED]
| Line | USD |
|---|---|
| Invoice — usage | $9,464.21 |
| Invoice — fixed pools | $252.00 |
| Invoice — gross | $9,716.21 |
| Vendor credit (separate line) | $0.00 |
| Invoice — net of credit | $9,716.21 |
| Reconciled (per-request recomputed) | $9,181.07 |
| Untracked spend (telemetry gap) | $283.14 |
| Unexplained residual | $0.00 |
Three distinct quantities reconcile to the invoice total — do not conflate them:
1. Tracked spend, reconciled per request — $9,181.07, the 94.49% coverage figure, tied to the invoice at a residual of $0.00 (cent-exact).
2. Untracked spend — $283.14 (2.91%), invoice spend the telemetry did not cover (UNCOVERED tier).
3. Invoice-verified fixed pools — $252.00, subscription or committed lines not billed per request (T2 INVOICE-VERIFIED).
With $0.00 unexplained residual, these sum to the invoice total of $9,716.21. Residual and untracked are different things: the residual is the reconciliation error on tracked spend — it measures how exactly tracked dollars tie to the invoice, not how much of the invoice is covered. Untracked spend is invoice dollars the telemetry never saw. A small residual therefore does not imply full coverage; the uncovered remainder is disclosed above, not lost. Credits are shown as a separate line, never allocated per feature.

Unit economics carry a heavy-user margin tail
[T1 RECONCILED] cost · [T3 MANAGEMENT-DECLARED] revenue. [EV-04, EV-07]
Negative-margin cohorts: 1, totalling $423.59 of margin gap (shown separately, outside waste — a cost legitimately incurred). Unit-economics-quality index 80.9 (green). Revenue is management-declared (T3).
Reconciled cost trends across the period history; revenue remains a single period
Historical reconciled cost. No forward projection. [EV-01]
[T1 RECONCILED]
| Month | Reconciled cost | Requests |
|---|---|---|
| 2026-05 | $19,916.59 | 778,751 |
| 2026-06 | $9,181.07 | 354,899 |
Revenue is available for a single period only; a margin trend requires two or more revenue periods (limitation disclosed).
Under price and load stress, costs move as the price table dictates
T1 rows are deterministic replays of the reconciled request set; T3 rows are labelled hypotheticals. The Basis column states each scenario's cost basis — most replay the reconciled usage, while credit-expiry moves the invoice from net-of-credit to gross (gross and net are never mixed unlabelled). Routing envelopes are mathematical bounds — the cost if the entire existing workload were forced onto a single model, assuming no quality constraint — not achievable configurations and not a recommendation; unlike a provider price change, which moves every request's actual price, an envelope changes no price and only re-routes hypothetical traffic.
