Client Payments

Pay an invoice, retainer,
or engagement deposit.

Every engagement runs against a signed engagement letter and a numbered invoice. Payment is by ACH bank transfer or wire — the two methods your treasury team already uses for vendor payments. Nothing here replaces the engagement letter; it is simply how the money moves.

Accepted payment methods

Two methods, both bank-to-bank. Cards are not accepted — processing fees on a six-figure remediation run into the thousands, and that money belongs in your remediation, not in an interchange fee.

ACH Bank Transfer
Preferred

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, weekly remediation billing, and fixed-fee engagements.

Settles 2–4 business days  ·  Fee to you None
Domestic & International Wire
Accepted

Standard for global clients and for AP departments that route every vendor payment through treasury. Full remittance coordinates appear on each invoice; a W-9, W-8BEN-E, or bank letter is available on request.

Settles Same day domestic  ·  Best for Europe, Asia-Pacific, and LATAM clients

Pay by ACH

Secure hosted checkout, handled entirely by our payment processor. You authorize a one-time debit from your operating account; your bank credentials are never seen, stored, or transmitted by this firm.

Consultation Retainer
$1,500

Reserves a scoping call, document review, and a written preliminary risk assessment. Credited in full against the engagement fee if you proceed.

Pay retainer by ACH
Engagement Deposit
50% of scoped fee

Standard for audit and remediation engagements: 50% on signature to hold the dates, balance on delivery of the final report. The deposit amount is stated on your engagement letter.

Pay deposit against invoice
Hourly Advisory Block
$250 / hour

Mock inspection support, CAPA implementation review, and remote advisory. Purchase in blocks of 8, 20, or 40 hours; unused hours roll for 12 months.

Pay a specific invoice

Enter the invoice number exactly as it appears on your invoice (for example, GMP-2026-014). You will be taken to a secure hosted checkout to authorize an ACH debit. Paying by wire instead? Use the remittance coordinates printed on the invoice — no form needed.

ACH carries no surcharge to you. If your AP system requires a purchase order before payment, email the PO to the address on your invoice and we will bill against it on Net 30 terms. For invoices above $250,000, or for any international payment, use wire instead.

Remittance details

Full banking coordinates are printed on every invoice and provided in the engagement letter. They are deliberately not published on this page — vendor-impersonation fraud in pharma AP is common, and legitimate banking details should reach you inside a document you can verify.

W-9 on file. Current-year Form W-9 sent within one business day of request.
Certificate of Insurance. Professional liability and general liability; your entity can be named as additional insured.
Purchase orders accepted. Invoices reference your PO number and line items so AP can three-way match.
Net 30 standard. Net 45 and Net 60 accommodated for enterprise clients on request.
AP portal onboarding. Registration in Coupa, Ariba, Bill.com, Tipalti, or your internal supplier portal at no charge.
Mutual NDA before scoping. Executed before any facility, product, or inspection detail is exchanged.

Billing terms

Currency. All fees are quoted and payable in U.S. dollars.
Deposits. Audit and remediation engagements require a 50% deposit on signature of the engagement letter; the balance is due on delivery of the final report. Weekly remediation engagements are invoiced weekly in arrears.
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.

If the remediation roadmap was implemented and the FDA still issues a Warning Letter on a system covered by that roadmap, the engagement fee is refunded.
