Invoice Dispute Resolver
Example session with this skill installed
I received invoice INV-9902 for $4,500 from CloudScale. They billed 40 hours at $100/hr plus a $500 'setup fee' I never agreed to. My contract says the rate is $90/hr. I want to contest this.

I have analyzed the dispute for INV-9902. The primary issue is a Rate Mismatch combined with an Unauthorized Fee. There is a $900 discrepancy between the billed amount and the contractual terms.

Draft Communication to CloudScale
Subject: Formal Dispute: Invoice INV-9902 / CloudScale & [Your Company]
Dear CloudScale Billing Team,
We are in receipt of invoice INV-9902 for $4,500.00. We are disputing a portion of this invoice totaling $900.00 due to the following discrepancies:
Rate Mismatch: The invoice lists 40 hours at $100.00/hr. Per our signed agreement dated [Date], the agreed-upon rate for these services is $90.00/hr. This results in a $400.00 overcharge.
2.
Unauthorized Fee: A $500.00 'setup fee' was applied. This fee was not included in the original SOW or subsequent change orders.
We have processed a payment of $3,600.00 today, representing the undisputed portion of this invoice. Please issue a credit note for the remaining $900.00 so we may close this item in our records. We look forward to your confirmation by [Date + 5 Days].
Best regards,
[Your Name]

What you get
About this skill
Stop wasting hours arguing over invoices you cannot prove.
Invoice Dispute Resolution Analyst turns disputed invoices, billing records, contracts, spreadsheets, and email threads into a structured, evidence-backed resolution strategy. Instead of simply summarizing the dispute, it determines what is actually owed, what is contested, what the evidence supports, and what action to take next.
What You Get
Invoice Reconciliation Audits billed amounts line by line against contracts, quotes, supporting records, payments, and other available documentation.
Dispute Diagnosis Identifies the underlying issue, including rate mismatches, unauthorized work, scope creep, duplicate billing, short payments, and unsupported charges.
Evidence Assessment Scores each claim based on the strength of the available documentation and clearly separates verified facts from assumptions or disputed statements.
Resolution Strategy Recommends practical resolution paths such as credit notes, partial payments, payment recovery, settlement proposals, or escalation.
Ready-to-Send Communications Creates professional dispute letters, payment requests, counteroffers, and escalation messages designed to communicate the position clearly and preserve negotiation leverage.
How It Works
Build the Case — Extracts relevant facts from invoices, contracts, spreadsheets, PDFs, and email threads.
Reconcile the Numbers — Performs a line-by-line comparison and calculates supported, disputed, and undisputed amounts.
Assess the Position — Connects financial discrepancies to the available evidence and identifies the strongest and weakest parts of the case.
Build the Resolution Plan — Produces a structured dispute report, recommended next actions, communication drafts, and an escalation timeline.
Built For Real B2B Disputes
Use it when you need to:
Challenge vendor overbilling or unauthorized charges
Recover unpaid or partially paid invoices
Detect duplicate billing across invoices or service periods
Reconcile short payments against agreed terms
Prepare a documented response to a disputed invoice
Organize evidence before escalating a commercial dispute
Turn fragmented invoice and email data into one actionable case file
Why Use This Instead of a Basic Prompt?
A generic prompt may summarize an invoice dispute. This skill is designed to work through the numbers and evidence behind it.
It separates disputed from undisputed amounts, checks line-item discrepancies, identifies missing support, evaluates evidence strength, and converts the findings into a practical resolution strategy.
The result is not just a summary.
It is a structured case you can act on.
Deliverables
Depending on the case, the skill can produce:
Executive dispute summary
Line-item reconciliation table
Supported vs. disputed amount analysis
Evidence strength assessment

Payment recovery plan
Draft dispute correspondence
Counterproposal or settlement draft

Open issues and evidence checklist
Important Limitations
This skill provides business and financial analysis for dispute resolution. It does not provide legal advice, determine legal liability, access banking portals, verify external records, or process payments. Final decisions should be reviewed by the appropriate financial, legal, or commercial professional.
