BigCommerce
You are scaling past the limits of platforms like Shopify, need more open API capability, and lower transaction fees, but do not want to manage infrastructure.
Your business logic is so unique it requires rewriting core platform behaviour, and you have the budget and internal technical team to maintain it.
Key risk: Assuming that a SaaS platform means no developer costs for customisation. Teams frequently underestimate the need for bespoke storefront development and complex integrations, leading to unexpected project costs.
