Why merchants choose us
An Atlanta base and an Auckland team, so there are no idle days.
We work from a base in metro Atlanta and a development team in Auckland, so your day and ours overlap from both ends. Questions you send at the end of your day are usually answered before you start the next one, and calls are booked in your time zone. Projects move without idle days, and we do not block progress on live calls when async works better. Underneath it is the same custom Shopify development we run for direct-to-consumer brands, B2B wholesalers and hybrid stores.
If you have waited days for an agency to reply before, the split between Atlanta and Auckland is the fix: someone is always working on your store. We have been doing this long enough to have the handoff rhythm figured out.

Shopify Experts USA FAQ
Do you work with US Shopify merchants?
Yes. Yes, and most of our clients are in the United States. We work on Shopify and Shopify Plus builds, migrations and app development from our metro Atlanta base, quoting in USD and scheduling across every US time zone.
Can you handle US sales tax across multiple states?
Yes. Shopify Tax or Avalara configured for economic nexus by state, with correct product tax codes and marketplace facilitator rules. Multi-state sales tax is the single most common thing merchants get wrong on their own.
Do you set up US carriers and fulfillment?
Yes. USPS, UPS, FedEx and DHL with live rates or rate tables, plus ShipStation, ShipBob and 3PL integrations for merchants shipping at volume.
How do I hire a Shopify developer in the USA?
Check they are a certified Shopify Partner, ask for stores they engineered rather than designed, and confirm who you actually speak to. We publish our own apps on the Shopify App Store, which is checkable evidence of depth.
Who are the best Shopify experts in the USA?
The best fit pairs Shopify engineering with the commercial reality here: multi-state sales tax, carrier rate shopping and high-volume fulfillment. Judge on published apps and real builds rather than an awards page.
Can you set up Shop Pay, Affirm and Klarna?
Yes. Shop Pay, Affirm, Klarna, Afterpay, PayPal and Apple Pay through Shopify Payments. Accelerated checkout materially affects mobile conversion.
What does a US Shopify build cost?
Small fixes from USD 49, theme customization typically USD 99 to 1,000, a starter store USD 899 to 3,500, custom theme USD 3,500 to 12,000, migration USD 949 to 5,000, and enterprise or Shopify Plus work from USD 15,000, depending on catalog and integrations. Quoted fixed-price in USD before work starts.
Can you migrate our store from Magento, WooCommerce or BigCommerce?
Yes. Products, customers and order history migrated with a redirect map that preserves rankings, plus sales tax, carriers and USD gateways configured before cutover.
Do you build B2B and wholesale for US suppliers?
Yes. Customer-group pricing, volume tiers, net 30 and net 60 terms, purchase orders and a wholesale portal, using our own Shopify app so Shopify Plus is not required.
Can you integrate Shopify with NetSuite, QuickBooks or an ERP?
Yes. NetSuite and QuickBooks are common in US mid-market, and we build real-time inventory, order and customer sync with retry and error logging so failures surface rather than drift.
Do US merchants need Shopify Plus?
Often not. Plus earns its cost for checkout customization, Shopify Functions, very high order volume or multi-store setups. We will tell you when it is not justified.
Can you sell internationally from a US store?
Yes. Shopify Markets with local currency presentment, duty-inclusive pricing so international shoppers avoid surprise charges, and correct hreflang for regional versions.
Do you handle CCPA and US privacy compliance?
Yes. CCPA and CPRA consent handling, Shopify customer privacy API integration, and correct data handling in any custom app we build.
How long does a Shopify project take?
Theme customization 3 to 5 weeks, custom theme 8 to 12 weeks, migration 8 to 16 weeks, with a dated milestone plan rather than an open-ended estimate.
Do you work across US time zones?
Yes. We schedule around Eastern, Central, Mountain or Pacific and deliver against agreed milestones, so overlap is for conversations rather than a requirement for progress.
Do you support stores after launch?
Optional retainer only. You can run the store yourself, the code is yours, and there is no license fee.
Do you work with US agencies white-label?
Yes. We provide Shopify engineering for US agencies needing depth without hiring in-house, under your brand.
How do we start a Shopify project?
Tell us what you sell, your platform, catalog size and what is not working. We come back with a fixed-price USD quote and milestone plan at no charge.
