Service
Recover Amazon 1P deduction leakage — without handing over Vendor Central access.
I help mid-sized 1P vendors turn shortage claims, chargebacks, price claims, and co-op deductions into evidence-backed dispute packages your team reviews and submits. Amazon deducts first and explains later; claims age out while nobody owns them, and recoverable money quietly becomes a write-off. The desk makes sure the recoverable ones don't.
Deliverables
What you get
Every engagement returns the same decision-ready structure.
- Claims classified by type, with recovery candidates prioritized by amount, deadline, and evidence strength
- Missing-evidence flags — exactly what to pull: BOL carton counts, ASN details, EAN/UPC, invoices
- Deadline-risk list — what ages out next and when
- Recurring patterns by PO / ASIN / carrier / FC — what keeps causing the leakage
- Dispute-ready drafts your team reviews and submits — you stay in control of Vendor Central

Claims near deadline
| Claim | Amount | Days left | Action |
|---|---|---|---|
| CB-20115 | $650 | ~20 days | Submit ASN logs now |
| CB-20138 | $380 | ~34 days | No evidence retained — log root cause |
| SC-10041 | $4,820 | ~42 days | Dispute this week (draft attached) |
Plus: recovery candidates in priority order, an evidence-gap list (what's missing and where to get it), and recurring patterns by PO / ASIN / carrier / FC.
Dispute-ready draft (appendix)
Dispute type: Shortage claim — PO-77120 / Invoice INV-88213
Summary: Amazon's receiving record shows 192 units against 240 shipped and invoiced (48-unit shortage, $4,820.00).
Evidence attached: BOL showing 10 cartons / 240 units tendered and signed without exception; ASN transmitted same day matching 240 units; carton pack list with EAN/UPC-level counts.
Request: Reversal of the $4,820.00 shortage deduction — tendered quantity is fully documented and no carton-level exception was recorded at delivery.
Your team reviews, adjusts if needed, and submits in Vendor Central.
Process
How it works
Export
You pull the relevant Vendor Central reports. No login sharing, no software to install, anonymized data is fine.
Triage
I classify, reconcile, and prioritize — finance-grade matching of POs, invoices, ASNs, and shipment records. Every dispute recommendation is reviewed by a person; nothing is automated into a submission.
Submit
Your team reviews the dispute-ready package and submits inside your own Vendor Central account.
Getting started
What you can send safely
Most engagements start with an anonymized export. If it's enough to classify and prioritize, it's enough to triage.
Useful columns
Claim or deduction ID · claim type · amount · deduction date · PO number · invoice number · dispute deadline if shown. A raw Vendor Central export works as-is — CSV or Excel, no special format needed.
Fine to redact
Vendor name · account identifiers · customer data · pricing you consider sensitive · any fields not relevant to the claims. Redact first, send second — a mutual NDA is also available before anything moves.
Data handling & confidentiality
What happens to your files
Deduction data is sensitive — claim exports, POs, invoices, shipment records. Here is the exact policy, so legal and finance don't have to guess.
- Vendor Central credentials are never requested. Everything runs off exports your team pulls; no disputes are submitted on your behalf.
- Your files are used only for your engagement — never for training, benchmarking, marketing, or other clients.
- Deleted within 30 days after the engagement ends — sooner on request — with written confirmation.
- Private, access-controlled storage. Files stay in the studio's own workspace; they are never loaded into a client-facing platform or multi-tenant tool.
- AI tools never train on your data. Reconciliation runs on the studio's own pipelines; where AI assists with classification or drafting, it runs on paid plans configured so your data is excluded from model training. Every dispute recommendation is reviewed by a person.
- Mutual NDA available before the free sample triage — signed first if you prefer.
The same commitments are written into the privacy policy.

Free Sample Triage
10–20 recent claims (anonymized OK). You see the exact output before spending anything.
Free
Send sample claimsDeduction Triage Sprint
Past 90 days of deductions: full triage, dispute-ready drafts, recommended next actions. 5–10 business days.
Flat project fee — quoted with your sample triage
Monthly Deduction Desk
Ongoing: new-claim review, deadline watch, evidence chasing list, dispute drafts, status tracking, monthly summary.
Flat monthly fee — no % of recovery
For reference: a full-time deductions analyst runs $70k+ a year; contingency recovery firms keep 25–30% of everything recovered. The desk is a flat, predictable fraction of either.

Boundaries, so expectations are clear
- No recovery guarantees — I prioritize by evidence strength precisely because not everything is winnable
- I never take Vendor Central credentials; your team submits all disputes
- Client data is deleted within 30 days of an engagement ending — the full policy is in Data handling above
- Independent service — not affiliated with or endorsed by Amazon
