Edge cases, single-line nursing-bra brand vs full-range maternity retailer, what changes?
The two extremes have very different needs, honest cut:
Single-line brand (e.g. a nursing-bra-only brand with 4 styles × 90 size variants × 4 access-flap types):
- Shopify Plus is usually enough if you stay under 2,000 variants per style. Above that, Magento.
- Subscriptions are nice-to-have (replacement bras at 6-month cadence) but not core revenue.
- Registry sync matters less (nursing bras are post-baby; baby-shower gift-giving cycle is mostly over).
- Fit-guide UX is the #1 lever, build the best B-K cup matrix walkthrough on the internet and you win on word-of-mouth.
- Return-friendly policy is critical (~22% return rate, mostly cup-size adjustments postpartum).
Full-range maternity retailer (e.g. apparel + nursing + supplements + postpartum across 2,500+ SKUs, think PinkBlush, A Pea in the Pod, Seraphine):
- Magento + Hyvä is the right answer almost always. Shopify ceilings on variant count, FDA-DSHEA, subscription complexity, and B2B layering all hit at this scale.
- Trimester filter + due-date capture is foundational, without it the catalog feels generic.
- Registry sync (especially Babylist) drives 12-25% of revenue on a full-range maternity store.
- FDA-DSHEA labelling for the supplement SKUs is non-negotiable.
- Multi-region (US + UK + EU + AU) is usually on the roadmap within 18 months, pregnancy is universal but sizing isn’t.
- B2B layer (boutique baby stores, hospital gift shops) is worth $200k, $2M/yr at this scale. Adobe Commerce B2B Companies or Open Source + Aheadworks B2B Suite.
The middle case, a brand with 200-1,500 SKUs spanning 2-3 categories, is where the platform-fit conversation gets interesting. Shopify Plus is “good enough” up to about $5M GMV in that band; Magento becomes worth the migration cost above that. Hatch Collection famously stayed Shopify, A Pea in the Pod migrated to Magento, PinkBlush has always been Magento, three roughly comparable brands, three different choices. The trigger isn’t GMV alone; it’s the number of trade-offs you’re losing on Shopify (variants, FDA, B2B, multi-region) compounding.
