multiflow vs. Stax

Stax (formerly Fattmerchant, rebranded 2021) is a merchant-services company built on a subscription-pricing thesis. The pitch: instead of paying 2.9% + $0.30 on every transaction to Stripe or Square, you pay Stax a fixed monthly membership ($99-$199+/month across their tier structure) plus interchange passthrough plus a small per-transaction fee (usually $0.08-$0.15). For a merchant doing $30k/month in volume at ~1.8% average interchange, the math beats flat-rate by meaningful dollars.

They target SMB merchants who have outgrown Square/Stripe flat-rate economics but aren't large enough for a direct enterprise acquirer relationship. Their product surface includes an omnichannel POS offering, online payments, virtual terminal, recurring billing, and basic reporting. They're a reseller of underlying acquirer rails (historically First Data / Fiserv), not an acquirer themselves.

The subscription pricing thesis is legitimate for the target profile. SMB merchant at $30k-$200k/month, one brand or tight small-chain, mainstream vertical, omnichannel (card-present + online): Stax's membership + IC passthrough model saves real money vs. flat-rate competitors. We're not going to argue with the math.

Omnichannel SMB. If you have a brick-and-mortar location plus an online store and want one processor for both, Stax's unified POS + online stack is a genuine convenience. multiflow is e-commerce only and doesn't compete on card-present.

Fast SMB onboarding with transparent pricing. 1-3 days to go live with membership pricing laid out up front. multiflow's 10-day onboarding and custom pricing conversation is heavier than SMB merchants need.

multiflow's segment: operators running 3-20 brands across e-commerce and subscription, $500k-$50M combined volume, often in verticals Stax and similar mainstream SMB processors won't underwrite (peptides, nutra, SARMs, CBD, kratom, adult-adjacent). The pain profile is different: reconciliation across brands, per-brand descriptors, vertical-specialized acquirer placement, unified chargeback queue.

A portfolio of four brands on four separate Stax subscriptions costs $400-$800/month in membership fees alone, and still leaves the operator with four separate dashboards, four chargeback queues, and no consolidated reporting. That's the architecture multiflow replaces.

Our architecture: one orchestration layer above a vertical-specialized acquirer, per-brand soft descriptors, consolidated ledger, one chargeback queue. See how the layers fit.

Single brand, mainstream vertical, $30k-$200k/month, omnichannel. Stax's subscription + IC model is almost certainly better for you than flat-rate competitors and doesn't have the multi-brand overhead multiflow is built for. If you don't have a portfolio, you don't need portfolio orchestration.

SMB retail, salon, restaurant, professional services with both card-present and online volume. Stax's omnichannel is a real product. multiflow is e-commerce only and wouldn't cover your card-present swipe.

Fast SMB ramp. You want to be live in 3 days with transparent pricing you can evaluate on a single page. multiflow's motion is heavier and slower; Stax fits the SMB pace.

3+ e-commerce brands. The moment portfolio reconciliation enters the conversation, Stax's one-account-per-brand model starts to break. Membership fees multiply; dashboards multiply; descriptors drift. multiflow consolidates.

Restricted verticals. Stax's underwriting is mainstream SMB — peptide, nutra, SARMs, CBD, kratom, adult-adjacent operators will be declined. Vertical-specialized acquirers under multiflow orchestration is the standard path. See industry pages.

Mid-market volume where interchange passthrough without the SMB membership overhead makes more sense. At $1M+/month the membership savings curve flattens; direct IC+ via a mid-market acquirer under multiflow orchestration is more efficient. See pricing.

In theory an operator could run a card-present retail brand on Stax for POS + online and a separate portfolio of e-commerce brands on multiflow. Different rails for different channels. In practice, operators tend to consolidate on whichever tool fits the majority of their volume — splitting across Stax and multiflow is rare because the operator profiles diverge sharply.

We don't orchestrate above Stax accounts; Stax's architecture is single-merchant-account-per-subscription and doesn't fit under a multi-brand orchestration layer.
