Subscription / Membership Pricing

Also called membership pricing, wholesale pricing, zero-markup pricing, interchange-plus-zero

You pay a fixed monthly membership and get interchange at cost plus a small per-transaction fee. Excellent above a volume threshold, bad below it.

What it is

Subscription pricing replaces the percentage markup with a flat monthly fee. Interchange and assessments pass through at cost, and the processor adds a small per-transaction charge instead of basis points. Stax is the reference implementation: published tiers of $99/month under $150,000 annual volume, $139/month for $150,000-$250,000, and $199+/month above $250,000, with interchange plus $0.08 card-present and plus $0.15 keyed, ACH at 1% capped at $10, and a $10/month PCI fee. Payment Depot and Dharma run comparable models. The math is a straight breakeven. Because your marginal cost per additional dollar of volume is essentially just interchange, the model gets cheaper per dollar the more you run. Below the crossover, the fixed membership dominates and you are paying more than a flat-rate account would cost. Published analysis puts that crossover around $10,000-$11,000 per month against flat-rate pricing. What you are actually buying is the removal of the percentage markup. On $75,000 a month, a 30 basis point interchange-plus markup costs $225; a $199 membership costs $199 and stops growing. As an illustration, at $150,000 a month the same comparison is $450 versus $199. The savings scale with you, which is the opposite of every other model in this glossary.

Why it matters to your business

As a rule of thumb, if you do more than about $75,000 a month with a healthy average ticket, subscription pricing is often the cheapest legitimate model available, and the savings compound as you grow. Going from a 30 basis point markup to a $199 flat membership on $150,000 a month is roughly $250 a month, $3,000 a year, and $9,000 a year at $300,000 a month. If you run high transaction counts on small tickets - a bar, a coffee shop, a QSR - do the per-item math before you sign anything. The percentage savings can be entirely consumed by eight cents times a lot.

Where it gets contested

Subscription pricing is genuinely good and it is also aggressively marketed with a misleading headline. 'Zero markup' and 'wholesale rates' describe the percentage only. The per-transaction fee is a markup. The membership is a markup. The PCI fee is a markup. Adding $0.08 to every card-present transaction on a 2,000-transaction month is $160, which is a 40 basis point equivalent on a $40,000 book - not zero. The second issue is the transaction-count blind spot. The model is priced for high average tickets. A bar running 4,000 transactions a month at an $18 average is $72,000 of volume and 4,000 x $0.08 = $320 in per-item fees on top of the membership. The same $72,000 at a $250 average ticket is 288 transactions and $23. Identical volume, wildly different outcome, and the sales page shows you the second scenario. Third, watch the tier boundaries. Membership tiers priced off annual volume can reprice you upward as you grow, sometimes automatically. Ask what happens the month you cross a threshold, and get it in writing.

How to check it yourself

Take last month's transaction count and card volume. Compute: (membership + count x per-item fee + PCI and other monthlies) / volume, and add your actual blended interchange. Compare that number to your current effective rate. Do it with your real transaction count, not your volume alone - the transaction count is what breaks or makes this model.
