Checklist for choosing a Shopify agency for a New York store

    On this page

      Choosing a Shopify agency for a New York store, or one that sells to New York customers, comes down to a few checks. Is the business real? Do you know who handles sales tax? Can you work across time zones? Does the team treat accessibility as part of the build? This guide is neutral advice for any agency, wherever based.

      You get a way to verify the business, sales tax facts for your adviser, a time zone overlap plan, what ADA.gov says about accessibility, tips for the directory and Clutch, and a proposal checklist. We read every source on 3 November 2026. For general questions, see questions to ask before hiring an agency.

      Verify the business entity

      The New York Department of State runs a Corporation and Business Entity Database. It covers corporations, limited liability companies, limited partnerships, limited liability partnerships and assumed name filings. The department's FAQ says the data is updated daily and that each result shows the current name, date of organization, county, service of process address, registered agent if any, and current status. The department says it relies on what filers submit and cannot guarantee the data is complete or accurate.

      • Match the legal name on the proposal and invoice to the entry, and check the status and date of organization.
      • The FAQ says corporations, limited partnerships and LLCs must generally use their true legal name or file an assumed name certificate. If the website name differs, ask for the legal name.

      An agency based elsewhere may not appear there. Ask for its legal name and where it is registered, then check that register. A record shows who you would sign with, not how good the work is.

      Sales tax: what the agency should and should not decide

      The New York State Department of Taxation and Finance (DTF) says anyone who will make sales subject to sales tax in New York must register for a Certificate of Authority, and should apply at least 20 days before starting.

      For a seller with no physical presence in New York, the DTF's nexus page, last updated 29 July 2026, says you must register as a vendor if, in the immediately preceding four sales tax quarters, both of these were true: gross receipts from tangible personal property delivered into New York exceeded $500,000, and you made more than 100 such sales. Meeting only one is not enough. The page says to file a certificate of registration within 30 days after the day you met both, and to begin collecting tax 20 days thereafter. It does not say exactly what those 20 days count from, so ask your adviser.

      Shopify Tax calculates and collects sales tax in the US, the EU, the UK and Canada, but Shopify says tax is your responsibility. You register with the tax agency, and you file and pay unless you use Shopify Tax with automated filing. Its US setup steps have you add each state where you are registered, with its sales tax ID. Its liability page adds that nexus rules differ by state.

      So the agency should configure what you and your tax adviser decide, and test it. Ask for test orders to New York addresses showing the tax lines, and a plain list of what was not set up.

      Time zone overlap if the agency is elsewhere

      New York is on Eastern Time. NIST says Eastern standard time (EST) is 5 hours behind UTC and Eastern daylight time (EDT) is 4 hours behind. Daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, which was 1 November this year.

      A good overlap plan sits in the proposal and names:

      • a daily window, stated in Eastern Time, when your contact is online and can talk live;
      • the working days and each side's public holidays;
      • how urgent problems, such as a broken checkout, are reported, who answers outside the window, and response times in writing;
      • a written end of day update, and release times inside your working hours so someone on your side can test;
      • what changes when the clocks change.

      Accessibility expectations for US stores

      The ADA.gov web guidance, dated 18 March 2022, says the Department of Justice has consistently taken the position that the Americans with Disabilities Act (ADA) applies to the goods, services, privileges and activities that businesses open to the public offer, including on the web. It says such businesses must take steps to provide appropriate communication aids and services, such as captions, where needed to communicate effectively with people with disabilities. It adds that, at that date, the Department had no regulation setting detailed web standards, that businesses have flexibility in how they comply, and that existing technical standards, including the Web Content Accessibility Guidelines (WCAG), give helpful guidance.

      Whether the ADA covers your store is a question for a lawyer. You can still set a clear target in the contract. Ask which WCAG version and level the agency builds to, how it tests (keyboard, screen reader, color contrast), which parts it cannot control, such as third-party apps, and who fixes problems found after launch. If you also sell to the EU, see our European Accessibility Act guide, which covers a different law.

      Payments and checkout

      Shopify's supported countries page says you can use Shopify Payments if your business is in a listed country, and the United States is listed. For US stores, Shopify's payment methods page lists Visa, Mastercard, American Express, Discover and Diners Club cards, and the wallets Apple Pay, Google Pay and Shop Pay. It does not list PayPal, Klarna, Affirm or Afterpay, so if you want any of them, ask how the agency will add them. If you ship into the US from abroad, see our guide to selling from the Middle East to the UK, Europe, the US and Canada.

      Shopify Partners and the directory

      Shopify's Partner Directory filters by services, location, industry, language, price range in US dollars and tier. Shopify says its default order favors active, certified and local partners. It lists four tiers: Select for small and medium businesses, Plus for mid-market and larger ones, Premier for large enterprises and Platinum for global enterprises. The partner program page says every partner starts on a Registered tier and can move up. The pages we read do not say what earns each tier or whether Shopify verifies partners. That page also says some earlier program brands ended, such as the Shopify Experts Marketplace in December 2023 and the Plus Partner program in December 2024. So ask which tier an agency holds today.

      Shopify sends review requests once a partner has had collaborator access for a week or more, and says reviews come from eligible merchants on a paid plan. Use the directory for a shortlist, then run the other checks.

      How to read reviews on Clutch

      Clutch says reviewers log in with LinkedIn, Google or a company email, and that it checks identity and work history. A useful review it cannot verify is published as Not Verified, so look for that label. Its methodology page, updated October 2026, says reviews carry the most weight in the core of its score, more than clients and experience or market presence, and that only verified reviews count. A directory's default order lists sponsored companies first, then verified providers, then the rest by rank, so check which listings are sponsored.

      • Favor recent reviews. Clutch says reviews from the last two years carry the most weight.
      • Match project size and type to yours, and read how problems were handled.
      • Ask where the work is done, and ask for a client you can call.

      What a fair proposal contains

      Ask for it in writing. To see what a Shopify project can include, read about Shopify solutions.

      • Legal parties: entity names and registration details on both sides, and whether prices include tax.
      • Scope: pages, templates, apps, integrations and migrations, plus a list of what is out of scope.
      • Milestones and payments: dated stages, what you receive and approve at each, and payments tied to them.
      • Tax and checkout setup: who configures sales tax and payments, who confirms the settings with your adviser, and which test orders prove them.
      • Time zone and accessibility: the overlap window, urgent contact route and response times, plus the WCAG version and level, the test method and what is excluded.
      • Ownership: the store, domain, theme code, design files and app accounts sit with you. Shopify says owners approve a collaborator request, choose its permissions and can remove access later, and that collaborators cannot receive store ownership. See also who owns the code.
      • Handover and support: documentation, an admin walkthrough, removal of the agency's access at the end, and what support covers after launch, for how long and at what price.

      Questions to ask

      1. Which legal entity will sign, and where is it registered?
      2. Who decides where my store collects sales tax, and what will you configure and test?
      3. Which Eastern Time window will my contact be online, and who answers urgent issues outside it?
      4. Which WCAG version and level do you build to, and how do you test it?
      5. Which Shopify Partner tier do you hold today, and where is your directory profile?
      6. Whose Shopify account will hold the store, domain and apps?
      7. How will you test checkout on a phone with each payment method I offer?
      8. What support do I get after launch, and at what cost?

      Red flags

      • The agency cannot give a legal name or registration details, or the invoice name differs from the proposal.
      • It says it will handle sales tax for you or tells you where to register. Those decisions belong to you and your adviser.
      • Time zone cover is called flexible, with no hours or response times in writing.
      • It promises an ADA compliance badge or guaranteed result, with no test method.
      • It asks for your owner login instead of a collaborator request, or wants to create the store under its own account.
      • The scope is a few lines with no exclusions, or full payment falls due before any work is shown.
      • It promises rankings, traffic or sales.

      This is general information, not legal or tax advice. Check the current rules or ask a qualified adviser before you decide.
