The $50 Billion Opportunity Hiding in Plain Sight: Why B2B Payments Are Still Stuck in the Past
By Nationwide Payment Systems — Payments Powered by People
B2B Payments – why your business needs to accept CARDS!
In a world where consumers can tap to pay for coffee in seconds, it’s almost unbelievable that U.S. businesses still cut paper checks to pay other businesses. Yet according to data from NACHA and the Association for Financial Professionals (AFP), roughly one-third of all B2B payments in North America are still made by check or wire.
That gap represents a massive — and largely untapped — opportunity. Industry analysts estimate tens of billions of dollars in potential digital payment volume that has yet to move onto faster, cheaper, smarter rails like ACH, virtual cards, and real-time payments.
For companies in fintech, invoicing, and merchant services, this is the next frontier — the $50 billion opportunity sitting in plain sight.
People want to pay business bills the same way they pay a personal bill, get a link -click and pay and not get out the check book or organize a wire to be sent out! – Card holders get the benefit of getting miles, points or cash back! They want to press the EASY BUTTON!

The B2B Payments Landscape in 2025-2026
| Payment Method | % of B2B Transactions (US & Canada) | Trend vs 2020 | Key Notes |
| Checks | ~33% | ▼ Down from 42% | Still common among SMBs & legacy systems |
| ACH / EFT | ~45% | ▲ Up sharply | Fastest-growing method (NACHA) |

Even with explosive ACH growth (worth $86.2 trillion in 2024), 30–40% of B2B transactions still rely on paper checks or wires.
If just 10% of those converted to digital, it would represent $50 billion+ in new digital payment volume — and major efficiency gains for American businesses.
Why Businesses Still Use Checks and Wires
Despite abundant fintech innovation, many organizations remain anchored to outdated processes because:
- Accounting or ERP systems aren’t integrated with payment gateways.
- Vendors and customers are slow to change established routines.
- Bank fees, reconciliation, and trust concerns create friction.
- Manual approval workflows still rely on signatures and paper.
Ironically, many of these companies already use digital payments — for payroll, subscriptions, or personal banking — but haven’t applied the same logic to vendor payables or receivables.
The Push Toward Digital: ACH, Cards & Smart Invoicing
Modern B2B platforms are closing that gap.
NPSONE Smart Invoicing, for example, helps businesses modernize with:
- Instant digital invoices including payment links for ACH or credit card.
- Recurring + subscription billing to streamline collections.
- QuickBooks sync for automated reconciliation.
- Customer self-service portals to simplify payments.
Each paper check replaced with a digital payment saves $4–$6 in labor, materials, and delays — while improving cash flow and visibility.
The “Untapped $50 Billion” Explained
Visa, Mastercard, and Amex don’t publish an exact “untapped B2B payments” figure, but all have described B2B as the largest remaining greenfield opportunity for digital payments.
- Visa B2B Connect, Mastercard Track, and Amex Payment all target this migration.
- NACHA’s B2B ACH volume continues double-digit growth each year.
- Analysts estimate tens of billions in volume still flowing through paper or wire channels that could convert to digital.
For solution providers like Nationwide Payment Systems, this isn’t theory — it’s the real frontier of merchant services.
