Headless commerce & PIM
Composable storefronts on commercetools, Shopify Hydrogen or custom stacks, with PIM, MDM and a single product backbone across all channels.
Industries GDPR PCI DSS
RetailTech and Omnichannel Software Development Services for US & EU Retailers
YuSMP Group builds retail software for US and EU brands that sell across web, app, store and marketplace. We engineer headless storefronts, mobile shopping, POS and in-store inventory, customer data platforms, on-site personalization and loyalty stacks that share one product, pricing and customer model. PCI DSS scope stays minimal, GDPR and CCPA stay clean, WCAG 2.2 AA stays measurable. Recent omnichannel rebuilds have lifted conversion two to four points without rebrand risk.
Our retail practice covers six core lanes: headless commerce and PIM rebuilds for brands outgrowing their first platform; mobile shopping apps with native checkout and push-driven re-engagement; POS, in-store inventory and click-and-collect for retailers that operate physical stores; customer data platforms unifying web, app, store and CRM signal; personalization and search on first-party data; and loyalty plus subscription billing engines. We work under PCI DSS v4.0 for the payment surface, GDPR plus ePrivacy for EU customer data, CCPA for US opt-outs, and ADA plus WCAG 2.2 AA for accessibility. GS1, EDI and EAN/UPC underpin omnichannel SKU integrity.

FAQ
Retail FAQ
Do you migrate to headless commerce?
Yes. We decouple storefront from commerce engine and CMS, move catalog into a PIM, and roll out new categories progressively to keep revenue stable during the cutover.
How do you keep PCI DSS scope small?
We push card data into tokenized vaults or hosted fields with payment providers, then design adjacent services so they never see PAN. The audit boundary stays around a thin, well-instrumented zone.
Can you build POS and store-level inventory?
Yes. We deliver POS clients, offline-first inventory, click-and-collect, in-store fulfillment and returns flows that reconcile with the same product, pricing and loyalty data as web and app.
How do you handle ADA and WCAG 2.2 accessibility?
We build to WCAG 2.2 AA from the design system up, run axe and manual screen-reader passes per release, and document conformance to reduce ADA Title III demand-letter exposure in the US.
Do you work with GS1, EDI and EAN/UPC standards?
Yes. We model catalogs around GS1 GTIN, run EDI EDIFACT and ANSI X12 exchanges with suppliers and 3PLs, and validate EAN/UPC for omnichannel SKU integrity.
How do you handle GDPR and CCPA for personalization?
We deploy a consent management platform, server-side tagging and first-party data pipelines, plus DSAR and opt-out automation so personalization stays GDPR-aligned (EU) and CCPA-acknowledged (US) after the third-party cookie sunset.
