Accepted payment methods
Both methods are bank-to-bank. Cards are not accepted — processing fees on a large engagement run into the thousands, and that money belongs in your quality program, not in an interchange fee.
Direct debit from your operating account, authorized once through a secure hosted checkout. No surcharge is passed through to you and no banking details are exchanged by email. The right choice for deposits and fixed-fee engagements.
For clients outside the United States, whose banks cannot send ACH. Wire instructions are sent directly by Roberto on request and are never printed on invoices, which protects you against payment fraud. A W-9, W-8BEN-E, or bank letter is available on request.
Pay a specific invoice
Enter the invoice number exactly as it appears on your invoice (for example, INV-2026-0001). You will be taken to a secure hosted checkout to authorize an ACH debit. Paying from outside the United States? Email gmpauditingandconsultingllc@gmail.com for wire instructions.
Remittance details
Banking details are never printed on invoices or published on this page. U.S. clients pay through the secure ACH checkout above; for an international wire, Roberto sends the instructions to you directly on request. Vendor-impersonation fraud in pharma AP is common, so confirm wire instructions by phone before the first payment.
Vendor onboarding
Large manufacturers cannot pay a consultant who is not set up in their vendor master. Everything your procurement team needs is ready before you ask for it.
Billing terms
Currency. All fees are quoted and payable in U.S. dollars.
Deposits. Day-rate audit and assessment engagements: 50% of the fee on signature to hold the dates, balance on delivery of the final report. The deposit amount is stated in your engagement letter and is invoiced and paid below like any other invoice.
Terms. Net 30 from invoice date unless otherwise agreed in the engagement letter.
Expenses. Travel, lodging, and reasonable expenses are billed at cost outside the Philadelphia metro area, with receipts.
Cancellation. Engagements cancelled with fewer than 10 business days' notice are billed at 50% of the scheduled on-site fee, reflecting dates held and travel booked.
Zero Warning Letter Guarantee. Applies to audit engagements only; assessments (including Clinical Phase GMP Assessments and the Pre-Approval Mock FDA Inspection) and hourly services are not covered, because assessment recommendations are implemented at the client's discretion. If every audit finding was fully addressed before the FDA inspection and the FDA issues a Warning Letter to the audited site on what was cited in them, within 12 months of the audit report, the professional fee is refunded (travel and expenses excluded). Full terms are stated in the engagement letter, which governs.
Payment methods. ACH bank transfer for U.S. clients; international wire on request. Credit and debit cards are not accepted.
Security. ACH authorizations are handled entirely by a PCI-DSS Level 1 payment processor. This firm never sees, stores, or transmits your banking credentials, and will never email you a change of banking details.
