FAQs

Shopify Customization questions from Portsmouth

Will customisations survive theme updates?

Yes — we structure changes so they're upgrade-safe and versioned in Git.

Can you support our existing vendors and hosting in Portsmouth?

Yes. We coordinate directly with local Portsmouth-area hosts, DNS providers, and incumbent agencies. No politics, no finger-pointing — just getting the work done.

Can you take over from another shopify customization provider in Portsmouth?

Yes — handovers from other agencies and freelancers are common. We run a structured audit, inherit cleanly, and document everything as we go so you're never locked in.

What if our Portsmouth team needs to talk to a senior engineer urgently?

Clients on a care plan get a direct line to the senior on their account. One-off engagements get response within the SLA we agree at quoting time.
