09 — FAQ
Before we talk
Headless or monolith?
We recommend based on editorial velocity, team skills, and total cost of ownership — not trends.
Can you rescue a slow Shopify theme?
Yes — theme surgery, app rationalization, and Hydrogen paths are all in scope depending on goals.
Do you support B2B commerce?
Net terms, company accounts, and quote flows are common extensions on Shopify Plus and custom stacks.
