How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A Shopify and ecommerce development agency builds the store itself and then keeps it trading: the theme or headless front end, the app, payment and ERP integrations, migration off WooCommerce, Magento or PrestaShop, product data and checkout work, the speed and conversion fixes that follow launch, and the maintenance retainer that owns the store once real orders are running through it.
Twelve external firms serving Miami cleared that check, judged on what their own sites publish about building and running stores rather than on one ecommerce line in a services menu. Eight name Shopify by name, four name a client, and the shortlist stops where the evidence stops.
What does a Miami Shopify development agency actually deliver?
A built or migrated store, the payment, ERP and marketing integrations behind it, and someone accountable for speed and checkout after launch. Twelve external firms cleared our evidence check, eleven publish a Miami base, four name a client you can check, and none publishes a rate.
1. Web Tonic
About: Web Tonic builds stores inside one development programme, so the build, the demand that lands on it and the reporting are planned together rather than handed between suppliers. Miami briefs usually arrive as a replatform with live orders to protect, so we settle migration scope, redirects and who owns the code before we quote. A brand that only wants a theme installed cheaply will be better served by several of the firms below.

Frequently Asked Questions
Why does this Miami shortlist stop at twelve external firms?
Because the evidence bar removed the rest. We started from the digital, web and ecommerce businesses a Miami search surfaces, then read each site for published store work: Shopify or ecommerce service pages, migration write-ups, platform partner status or documented builds. Firms whose only reference to ecommerce was a menu item, whose sites were dormant, or whose own logo could not be verified did not survive the read. Twelve did, and we did not pad the list to reach a rounder number.
Which of these firms name Shopify rather than ecommerce in general?
Eight of the twelve: Digital Silk, Solved Puzzle, Astra Results, Anderson Collaborative, Heyday, Smash Interactive, On The Map and Raging Agency. The rest sell store building, web development or ecommerce growth without committing to a platform on the pages we read, which usually means the platform is decided per project. Ask which platform they would recommend for your catalogue and why, and ask it before the first invoice rather than after the theme is chosen.
Which Miami firms name clients you can check yourself?
Four. Digital Silk names Massimo Motor and Absolute Dogs, Anderson Collaborative names Washify and RUJO Boots, Heyday names Kae Sushi and Plaza Coral Gables, and Digital FX names Five Star Jewelers. The others credit nobody on the pages we read, which is not disqualifying for a small studio bound by client confidentiality, but it does mean references have to come out of the first call. Ask for two live stores in your category and permission to contact the people who commissioned them.
How should a brand compare quotes when almost nobody publishes a price?
Force every bidder onto the same grid. Not one of them publishes a build price or a retainer. Ask whether the quote is a fixed build or time and materials, what the post-launch retainer costs, whether the theme code is yours or licensed, who holds the Shopify Partner account, how redirects and historic order data are handled in a migration, and what a change request costs in month four. Two quotes for one brief routinely differ threefold on those lines.
Does the agency have to be inside Miami?
Not really, but you should know where they are. Eleven of the twelve publish a Miami base and Digital FX works from Miami Beach rather than Miami proper. Proximity matters for photography days, warehouse visits and stakeholder workshops, and almost nothing else in a build. What matters more is whether the developer writing your theme is an employee or a subcontractor, and which timezone they answer support tickets from.
Choosing a Shopify Development Agency in Miami
Eleven of the twelve external firms publish a Miami base, so location alone will not narrow this list. Specialism does: eight commit to Shopify in writing.
Four name a client you can verify. Not one of them publishes a build price or a retainer. Ask what the retainer after launch costs and who owns the theme code when the contract ends.
Migration, not design, is what usually goes wrong. If you are moving a live store, ask how redirects, historic orders and customer accounts are handled, and who is accountable in the first week of trading.
Whoever you brief, insist the build and the demand that lands on it are read in one report, because a fast store nobody visits is a design project rather than a commercial one. If you would rather have the build, the growth programme and the reporting in one place, read our latest analysis or see how we work in Miami.
