Evaluate Merchant Processing Fees

Audit net deposits vs. gross processing fees to see where you are losing margin and how to reduce fee leakage.

Business Value

Reveals what card processing actually costs you, as opposed to what the advertised rate implies. Instant-payout charges, cross-border surcharges, and dispute fees are individually small and buried inside net deposits, making them incredibly easy to overlook in day-to-day operations. By automatically calculating your true processing costs and identifying fee leakage, this prompt gives you a clear financial breakdown and an actionable checklist to immediately reduce overhead and protect your profit margins.

Verified Prompt

Act as a payment processing consultant.

My account shows net deposits and fee debits from [Insert Processor, e.g., Stripe, Shopify, or Square] over the last [Insert Number, e.g., 90] days.

  1. Calculate my total gross customer sales, total processing fees deducted, and net cash actually deposited into my Grasshopper account.
  2. Calculate my true effective fee rate as a percentage of gross sales (Total Fees ÷ Gross Sales).
  3. Compare that effective rate against my baseline target of [Insert Target Rate, e.g., 2.9% + $0.30 per transaction], and tell me whether — and by how much — I'm exceeding it. Note if cross-border fees, instant payout fees, or chargebacks are visible drivers of the gap.

Present as: a summary table (Gross Sales / Total Fees / Net Deposited / Effective Rate / Target Rate / Gap). Add one line noting these figures reflect only what's visible in the Grasshopper transaction data and should be cross-checked against the processor's own dashboard, since not all fee types may appear identically in bank data.

OUTPUT: Produce exactly these two sections, in this order, with these exact headings:

  1. Fee Summary A table with exactly these ten rows, in this order: | Line | Amount | |---|---| | Gross Customer Sales | ... | | Base Processing Fees | ... | | Instant Payout Fees | ... | | Cross-Border Fees | ... | | Dispute Fees | ... | | Total Fees | ... | | Chargeback Principal (lost revenue, not a fee) | ... | | Net Deposited | ... | | Effective Fee Rate (Total Fees ÷ Gross Sales) | ...% | | Excess vs Baseline | ...% | Then this reconciliation line, filled in with your numbers: Reconciliation: Gross Sales − Total Fees − Chargeback Principal = Net Deposited → [gross] − [fees] − [chargebacks] = [net] ✓/✗
  2. Savings Checklist Exactly 3 rows: | # | Change | Est. Monthly Savings | Trade-off | |---|---|---|---| | 1 (EXAMPLE) | Turn off instant payouts | $120.00 | Cash arrives 2 business days later |

RULES: If any portion of the prompt is incomplete, please flag it immediately and prompt me back to ensure all portions of the prompt are filled out.

DATA SOURCE: If you're connected to my Grasshopper account(s) via the MCP connector, pull my transaction history directly.

Why it’s structured this way

This prompt is engineered to parse transactional fee debits with strict mathematical formulas, ensuring your fee analysis is built on hard ledger numbers rather than high-level estimates.

  • Parameter-Driven Detection: You set the matching criteria, within a window of days you choose. Explicit dials mean the same file produces the same findings every time, and you can tighten or loosen the check deliberately rather than hoping the model calibrates the way you’d want.
  • Anti-Overreach Guardrail: The prompt is expressly forbidden from stretching its criteria to produce a finding, and must return the exact phrase “NO DUPLICATES FOUND” on a clean month. A tool that always finds something trains you to ignore it; a clean result has to be a real, trustworthy outcome.
  • Constructive, Non-Accusatory Framing: Flagged transfers are paired with the specific receipt or invoice to locate, never characterized as improper. The output is a documentation task list, which is what’s actually useful and what keeps the exercise focused on preparation rather than suspicion.
  • Import-Ready Output: Reformats the full transaction list with fixed columns and a blank category field, eliminating the re-keying step between your bank statement and your accounting software.
  • Data Grounding & Stability: Connects directly to live account data via our MCP-based AI Connector, allowing the AI to securely extract your processor’s transaction footprints and calculate your true effective fee rate without manual data entry.
