Have you worked with boohoo / PrettyLittleThing / THG-style multi-brand DTC clients?

Yes, anonymised because of NDA, but the case-study angle is real. We shipped a Magento 2.4 + Hyvä rebuild for a Northern Quarter streetwear DTC: UKFast Manchester DC hosting, Klarna + Clearpay + GoCardless BACS rails, Boxing-Day survived at 60× normal traffic with sub-100ms TTFB. For a THG-style multi-brand DTC aggregator we built a shared-catalogue + multi-storefront Magento across 8 brand-named storefronts (separate domains, separate themes, shared product/inventory/order pipeline), unified BACS payout to one parent merchant, per-brand VAT invoicing into Sage 200. For a Trafford Park B2B wholesale portal we built customer-specific catalogues, VAT-number-gated trade pricing, BACS Direct Debit via GoCardless with Net-30, and MTD-compliant invoicing into Brightpearl. References available on signed NDA, brand names withheld per UK fast-fashion industry custom.
