For a US Shopify brand, the three things that predict whether an agency works out are timezone overlap with whoever runs your account, experience at your revenue stage, and whether the person who pitched you is the person doing the work. Office location matters far less than any of them.
Here's what to check, and where the offshore-versus-domestic question actually lands.
The four checks
| Check | What you want | How to verify |
|---|---|---|
| Timezone overlap | 4+ hours of shared working time with the person on your account | Ask where the strategist sits, not where the company is registered |
| Stage experience | Has run US paid media at your revenue level | Ask for a brand at your stage and what the constraint was |
| Who does the work | Named strategist, introduced before you sign | "Can I meet whoever will run the account?" |
| US market specifics | Understands US shipping expectations, sales tax display, seasonality | Ask how they'd handle BFCM planning |
Timezone matters, location mostly doesn't
The real question isn't which country the agency is in. It's whether you can get a decision made the same day.
Paid media has a daily rhythm — a creative dies, spend needs reallocating, a feed breaks. If your strategist is twelve hours away, every decision costs a day. Over a quarter that's material.
Four or more hours of overlap is usually enough. Ask specifically: *"What hours does the person on my account work, in my timezone?"* Not where the office is — where the person sits.
Plenty of excellent agencies serving US brands are not headquartered in the US. Plenty of poor ones are. The overlap question sorts it better than the flag does.
Stage experience is the underrated one
An agency that scales $500K/month budgets is not automatically good at taking a brand from $300K/year to $800K/year. Different constraints entirely.
At $200K–$1M, the constraint is usually the offer, the landing page, or attribution — not media buying sophistication. At $5M+, it's creative volume and channel diversification.
Ask this: *"Tell me about a brand you worked with at roughly my revenue. What was the constraint, and what did you change?"*
A specific answer names a bottleneck and a fix. A vague one lists services. We wrote about how the constraint moves in what profitable Shopify brands do differently at $500K, $1M and $3M.
US market specifics worth testing
Four things that catch out agencies without US ecommerce experience:
- Shipping expectations. Free shipping thresholds and delivery speed materially affect US conversion rates and belong in the offer conversation, not just the ads.
- Sales tax display. Tax added at checkout rather than shown in the price is a known US drop-off point.
- Seasonality. BFCM is not a week in the US — it's a six-week arc. An agency that starts planning in November is late. Ours is written up in the BFCM playbook.
- Attribution after iOS changes. Platform-reported ROAS overstates. Any agency serving US DTC should reconcile against Shopify without being asked.
Ask how they'd approach BFCM for your brand. The answer separates people who've run US retail calendars from people who haven't.
Where we fit
We work with US and Canadian Shopify brands, typically $200K–$3M — 15+ brands and $2M+ in managed ad spend, 100% Shopify. $2,000/month, published, no discovery call needed to see the number.
The approach is fundamentals before scale: we don't increase spend until the offer, page and measurement underneath it work. A DTC apparel brand cut CAC by 38% in three months on unchanged spend that way, and a pet products brand had $12,000/month of waste removed without revenue dropping.
Where we're the wrong fit: brands above roughly $5M, anyone needing in-house video production or multi-market management, and anyone on a platform other than Shopify. The full comparison of agencies covers who to look at instead.
Questions to send before any call
Email these to every agency on your list. Replies beat discovery calls for comparison:
- What's your monthly retainer for [scope] at [revenue]?
- Who would run my account, and what hours do they work in my timezone?
- Tell me about a US brand at my revenue stage — what was the constraint?
- Does the retainer include creative production and landing page work?
- Do I own the Business Manager, ad accounts and pixel?
That last one matters more than most brands realise — the contract terms breakdown explains what it costs to get wrong.
What to do today
Send those five questions to your shortlist. Note two things: what they answer, and how long it takes.
An agency that replies within a day with specific numbers is showing you how they'll communicate for the next twelve months. One that insists on a call before answering question one is showing you that too.
Ours: $2,000/month, named strategist introduced before you sign, US and Canada hours, creative direction and landing page audit included, production quoted separately, and you own every account. Book a 20-minute call and we'll tell you what we'd fix first, before you pay anything.
