PAYMENT PROCESSING FOR ECOMMERCE
Ecommerce Payment Processing:
Competitive Interchange & High-Risk Merchant Solutions
Payment processing is one of the most under-optimized line items in ecommerce — most merchants accept Stripe's default 2.9% + $0.30 without ever testing interchange-plus alternatives. 1Digital® arranges competitive processing partnerships and high-risk merchant accounts for verticals (firearms, cannabis-adjacent, supplements, adult, CBD) where standard processors don't serve.

How Payment Processing Optimization Compounds Margin
Payment processing fees are routinely one of the largest variable cost lines for ecommerce operations — and one of the least-optimized. Stripe's default 2.9% + $0.30 is a fair starting point for new merchants, but mid-market and enterprise operations leave significant margin on the table by not testing interchange-plus pricing models, processor-specific alternatives (Authorize.Net, Worldpay, TSYS, NMI), or platform-native payment programs (Shopify Payments at scale-discount tiers, BigCommerce Buy Now Pay Later integrations). A 30–80bp reduction in effective rate on a $10M annual processing volume is $30K–$80K of annual margin recovery.
For high-risk verticals (firearms, ammunition, cannabis-adjacent, CBD, vape, supplements, adult, regulated financial products), standard processors don't serve at all — Stripe, Square, PayPal, and Shopify Payments all prohibit most high-risk categories. 1Digital® arranges high-risk processor partnerships (Easy Pay Direct, Clearent, TSYS High Risk, specialized 2A-supportive processors for firearms, hemp-and-CBD-specific processors) that keep verticals operational without payment-processing risk. We work with platform partners across Shopify Plus, BigCommerce, Magento, and WooCommerce on the integration side.

Payment Processing — FAQ
How much can payment processing optimization actually save?
For mid-market merchants processing $5M–$50M annually, switching from default flat-rate (Stripe at 2.9% + $0.30) to interchange-plus pricing typically saves 30–80 basis points on effective rate — that's $15K–$400K of annual margin depending on volume and average transaction size. The savings come from passing through interchange fees at cost plus a fixed markup, rather than absorbing processor margin on every transaction. Enterprise volume ($50M+) typically achieves further savings through direct processor relationships and volume-discount tier negotiation.
What about high-risk merchant processing for regulated verticals?
Stripe, Square, PayPal, and Shopify Payments all prohibit firearms, ammunition, most cannabis-adjacent products (including hemp-derived intoxicants in many cases), CBD in some jurisdictions, vape, adult, regulated financial products, and high-chargeback categories. High-risk processors (Easy Pay Direct, Clearent, TSYS High Risk, Authorize.Net via high-risk gateways, vertical-specific processors like Square's firearms-friendly alternatives) serve these verticals at higher effective rate (3.5–5.5% typical) but keep operations functional. The right processor selection depends on vertical, chargeback profile, average ticket, and integration platform.
How do Buy Now Pay Later integrations fit into payment processing strategy?
BNPL (Affirm, Klarna, Afterpay, Sezzle) shifts financing risk to the BNPL provider in exchange for processor fees of 3–7% — significantly higher than card processing, but with documented AOV lift (varies widely by category, often 20%+) and conversion lift on higher-AOV categories. The economics work when AOV lift exceeds the marginal processor fee difference; they don't work for low-AOV categories where BNPL premium fees aren't offset by AOV gains. Decision should be data-driven per vertical and average order value tier.
What chargeback and fraud-screening tools do you recommend?
Depends on chargeback profile and AOV. For high-AOV ecommerce ($150+ AOV): Signifyd or Riskified with chargeback guarantee. For mid-AOV ($30–$150): NoFraud or Kount with rules-engine fraud screening. For platform-native solutions: Shopify Plus Fraud Analysis, BigCommerce's built-in fraud tools, Magento's Magento Commerce fraud detection. The right tool minimizes manual review on legitimate orders while catching the fraud patterns that produce 1–3% chargeback rates without screening.
How long does payment processing migration take?
For mid-market processor switching (Stripe to interchange-plus alternative): 2–6 weeks including underwriting, integration, and testing. For high-risk merchant account setup: 3–8 weeks including underwriting (high-risk underwriting takes longer), integration with platform-specific gateway, and chargeback monitoring setup. For enterprise direct-processor relationships: 6–12 weeks given negotiation, contract, and engineering integration. Migration timing should align with low-traffic periods to minimize risk of transaction-flow disruption.
