Consulting Firms: The Hidden $750 Fee on a $25,000 Project Payment

Consulting firms process large project payments and retainers. Network Offset Pricing eliminates the cost.

By David C.

Key Takeaway

Consulting firms process large project payments and retainers. Network Offset Pricing eliminates the cost.

Consulting is a high-invoice business. Monthly retainers of $5,000–$25,000, project milestone payments of $10,000–$100,000, and advisory fees create significant card processing volume. When clients pay by card, your processor takes 2.5%–3.5% of every dollar.

A $25,000 milestone payment at 3% costs **$750 to process**. For a consulting firm processing $50,000–$300,000/month in client card payments, annual fees reach **$15,000 to $126,000**.

The Consulting Processing Problem

Enormous Per-Transaction Costs

Premium and Corporate Cards

Corporate clients almost exclusively use corporate credit cards or premium rewards cards — the most expensive card types to process at 2.3%–2.7% interchange.

Client Convenience vs. Firm Cost

Consulting firms accept cards as a client convenience. The client prefers card payment for cash flow management, rewards, and simplicity. The firm absorbs $300–$1,500 per payment in processing fees for that convenience.

Network Offset Pricing for Consulting

Invoice example:

Why Consulting Clients Accept It

  • B2B norm. Corporate clients encounter network offset pricing across vendors.
  • Large payments strongly incentivize ACH/wire. Saving $1,000 on a $25,000 payment is a no-brainer. Most clients switch to ACH.
  • Firms already differentiate pricing by payment terms. Net-30 vs. Net-60 pricing is standard. Cash vs. card pricing follows the same logic.
