Cost + timeline for a sporting goods Magento build (or migration from Shopify)?

Realistic ranges for a sporting goods brand at $2M, $10M GMV:

• Magento + Hyvä rebuild: $30k, $80k. Sporting-goods-specific scope adds: variable sizing matrix per category ($5k, $10k), fitment quiz per category ($6k, $15k each), personalization Custom Options + 1-2 partner integrations ($6k, $15k), team / club roster CSV importer ($8k, $18k), MSI + click-and-collect ($10k, $25k), B2B layer if team orders are above 15% (+$8k, $25k).
• Timeline: 10-16 weeks for a typical mid-market sporting goods store. Faster (8 weeks) if SKU count is small and category mix is narrow (e.g. running shoes only); longer (16-24 weeks) for full team-sports + retail integration + multi-region.
• Hosting: $400, $1,500/mo on Cloudways / dedicated. Sporting goods needs over-provisioned for seasonal spikes, assume 4-8x base traffic during peak windows. CDN (Cloudflare / Akamai) mandatory.
• Ongoing: $1.5k, $5k/mo retainer for through-season ops (pre-snow load test, mid-season roster reorders, partner SLA monitoring, fitment-quiz iteration).

Risks specific to sporting goods migration:

• Variant-product mapping is fiddly, Shopify treats “Size: 10, Width: D” as one option pair; Magento separates size and width into independent attributes. Migration script needs to flatten + reshape (especially for footwear).
• Personalization order history must migrate, team rosters from previous seasons are gold for mid-season reorder rate.
• SEO: redirects must cover product URLs (Shopify /products/<handle> → Magento /<url-key>.html) AND category URLs AND variant deep-links AND personalization-product URLs. Miss any of these and you drop 20-40% of organic for ~6 weeks, brutal in a seasonal vertical.
• Time the cutover for the off-season window, ski brands cut over April, August, golf brands cut over October, January, team-sports brands cut over March, May (between basketball + football seasons).

Run both stores parallel for 30 days behind a feature flag, only flip DNS once redirects map ≥98% of traffic + 30 successful test orders + 1 dry-run team-roster import. Sporting-goods migrations done well don’t lose ranking; done badly they take a season to recover.
