Pricing Model

Membership / Subscription Pricing Explained

Membership pricing replaces the per-transaction percentage markup with a flat monthly fee. Interchange is passed through at cost. It's sometimes described as "wholesale" processing because the processor's margin comes from the membership fee, not a per-transaction cut.

Quick Answer

Under membership pricing, you pay a monthly membership fee plus interchange and assessment fees at cost, plus a small per-transaction fee (cents, not a percentage). There is no percentage-based processor markup per transaction. The monthly fee funds the processor's service. At higher volumes, eliminating the per-transaction percentage markup can reduce the effective rate compared to interchange-plus or flat-rate.

How Membership Pricing Works

In interchange-plus pricing, processors charge a percentage markup per transaction (e.g., 0.25% + $0.10). That percentage scales with volume — the more you process, the more the processor earns from markup. Membership pricing breaks this scaling by replacing the percentage markup with a flat monthly fee.

Under membership pricing, you still pay interchange (passed through at cost) and assessment fees (also at cost) and a small per-transaction fee covering transaction-level costs. But the processor's profit comes from the monthly membership fee — not from taking a percentage of each sale.

At low volumes, the monthly membership fee can make this model more expensive than alternatives. As volume grows, the absence of a per-transaction percentage markup means the effective rate decreases relative to interchange-plus. The crossover point depends on the specific fee structure of the provider and your average interchange rates.

When Membership Pricing May Work Well

Established merchants with consistent monthly volume who can absorb a fixed membership fee

Higher-volume businesses where eliminating per-transaction percentage markup produces meaningful savings

Merchants who already understand interchange-plus and want to reduce variable markup costs

Businesses with predictable card mix where interchange pass-through is well understood

When It May Not Fit

Low-volume or seasonal merchants where the monthly membership fee exceeds what the markup savings provide

Very new businesses without enough volume history to evaluate whether the math works

Merchants with highly variable monthly volume where the fixed fee becomes costly during slow months

Businesses that process primarily low-interchange transactions where the markup savings are smaller

Advantages

No percentage-based processor markup per transaction
Interchange passed through at actual cost — fully transparent
Effective rate tends to decrease as volume grows
Easier to audit: membership fee is fixed and known upfront

Trade-offs

Monthly membership fee is a fixed cost regardless of volume
May require minimum volume to make economic sense
Statements require understanding interchange to read accurately
Fewer providers offer this model than flat-rate or interchange-plus

Common Misconceptions

❌ Myth: Membership pricing means there are no per-transaction fees.

✅ Fact: Membership pricing eliminates the percentage-based processor markup per transaction — but interchange, assessment fees, and a small per-transaction cost still apply. The monthly membership replaces the markup percentage, not all fees.

❌ Myth: Membership pricing is always cheaper than interchange-plus.

✅ Fact: At low volumes, the monthly membership fee can make this model more expensive. Whether it's cheaper depends on your volume, card mix, and the specific fee structure of the provider. Calculate using your actual numbers.
