Spanish, Creole and the Checkout: What a Miami Website Has to Get Right

Most websites built for Miami are built for the United States and then given a Spanish toggle. That order is backwards, and it shows up in the places that cost money: a name field that rejects two surnames, a checkout that offers no instalments to a buyer who has never bought a sofa any other way.

Miami is a US city where a large share of customers conduct their commercial lives in Spanish, a meaningful share in Haitian Creole, and a growing share in Brazilian Portuguese. Your site still runs under Florida and federal law, prices in US dollars, and is taxed by county. Here is what has to be right at that intersection.

Language is the product, not a setting

English is the official language of the state under Article II, Section 9 of the Florida Constitution, adopted in 1988. Miami-Dade County went the other way: it passed an anti-bilingual ordinance in 1980, repealed it in 1993, and now routinely publishes public information in English, Spanish and Haitian Creole. That three-language pattern is a reasonable default for any business serving the county directly.

Which Spanish

There is no neutral Spanish in Miami. The city's Spanish is Caribbean and South American: Cuban in Hialeah and Westchester, Venezuelan in Doral, Colombian, Nicaraguan, Argentine and Peruvian across the county. Practical consequences for the build: use es-US in your hreflang and lang attributes rather than es-ES, never use vosotros forms, and get a human who lives in this market to review the copy. Castilian vocabulary reads as foreign here in a way that quietly undermines a local business.

Translation should be structural. Separate URLs per language, not a JavaScript swap, so Spanish pages can rank on their own. Spanish text also runs longer than English, so buttons and navigation need to survive the expansion without wrapping.

Haitian Creole and Portuguese

Haitian Creole matters in Little Haiti, North Miami and North Miami Beach, and it is genuinely underserved on the commercial web. If your customers are there, a Creole version is an advantage rather than a cost. Portuguese serves Brazilian buyers around Brickell, Aventura and Sunny Isles, and is usually worth doing only for property, luxury retail and professional services that actually sell to them.

The form fields that reject real customers

• Names. Spanish naming convention gives most people two surnames, the father's then the mother's. A last_name field capped at twenty characters, or validation that rejects spaces, turns Maria Fernandez Gutierrez into a support ticket. Allow accented characters and the letter ñ in every name field, and store everything as UTF-8 end to end.
• Addresses. Miami-Dade addresses carry directional quadrants, as in NW 7th Street, which address autocomplete handles and hand-typed validation usually does not.
• Phone numbers. Area codes 305 and 786 cover Miami-Dade, 954 covers Broward, 561 Palm Beach. Accept the country code too, because plenty of your visitors carry a Colombian, Venezuelan or Brazilian number and will use it.
• Dates. The United States writes MM/DD/YYYY and uses a twelve hour clock. Latin American visitors read DD/MM/YYYY by instinct. On any booking or delivery date, show the month as a word. It removes the ambiguity and costs nothing.
• Numbers. Dollar amounts here use a comma for thousands and a full stop for decimals. In Spanish and Portuguese that convention is reversed. If you localise number formatting automatically, check what 1,500.00 becomes on the Spanish pages.

Paying: US rails, imported expectations

The currency is the US dollar and the rails are American: card networks, ACH, Zelle for service payments, Apple Pay and Google Pay at the checkout. What is Miami-specific is who is holding the card.

• Instalments are an expectation, not a promotion. Customers who grew up paying in cuotas in Colombia or parcelamento in Brazil expect a per-month figure. The US equivalent is buy now pay later: Affirm, Klarna or Afterpay on the product page, showing the monthly amount and not only the total.
• Foreign cards get declined. Address verification compares the billing address to a US format, so a card issued in Bogota or Sao Paulo can fail in ways that look like fraud to a default gateway configuration. Review your risk rules before launch, or you will decline good orders all winter and never know.
• 3-D Secure behaves differently. International issuers challenge more often, so make sure your checkout handles the redirect and return without losing the cart.
• WhatsApp is a sales channel here. In most US cities a click to chat button is a nice extra. In Miami it is frequently where a high value enquiry actually closes, particularly in property, travel, trade and professional services. Put the number on the page and make sure someone answers it.

Tax has to be calculated from the address

Florida charges a six percent state sales tax and counties add a discretionary sales surtax on top, at rates that differ from county to county. A customer in Miami-Dade and one in a rural county can owe different amounts on the same order. Hard coding a single rate is wrong on day one and gets worse every time a county changes its surtax. Calculate from the destination address, through a tax service wired into the checkout, and register with the Florida Department of Revenue if you are selling in from out of state.

The legal floor in South Florida

Four things deserve attention before launch, and the first is not theoretical here.

1. 01Accessibility. The Southern District of Florida, which covers Miami, is one of the busiest federal courts in the country for website accessibility claims under Title III of the Americans with Disabilities Act. Small local businesses receive these demands routinely. Build to WCAG 2.1 AA and keep the audit on file. It is cheaper than settling.
2. 02Text and call consent. The Florida Telephone Solicitation Act requires prior express written consent for marketing calls and texts, and carries a private right of action. If your form collects a mobile number, the consent language has to be explicit, unchecked by default, and separate from your terms.
3. 03Privacy. The Florida Digital Bill of Rights took effect in 2024 and is enforced by the Florida Attorney General. Its core obligations reach only very large controllers, so most Miami businesses fall outside it, but the Florida Information Protection Act applies to everyone and sets deadlines for notifying customers after a breach.
4. 04Sector rules. Real estate sites must carry the brokerage's licensed name under Florida Real Estate Commission advertising rules, and law firm sites fall under the Florida Bar's advertising rules. In a city this dense with brokerages and firms, that comes up constantly.

How people find you here

Google dominates, but two local habits change the brief. Apple Maps carries real weight because iPhone share in this market is high, so an Apple Business Connect listing is not optional. Waze is unusually popular in Miami and across Latin America, and it pulls from its own listing data. Claim all three, and write your Google Business Profile description and services in Spanish as well as English, because a great deal of local search here is typed in Spanish.

Miami also sits on the main interconnection point between North and South American networks, which is why so much Latin American traffic passes through downtown. If your audience includes Bogota, Lima, Caracas or Sao Paulo, hosting in or near Miami buys you latency that European or West Coast hosting will not.

The calendar the build has to survive

Atlantic hurricane season runs from 1 June to 30 November. That is half the year in which your site may need to publish a closure notice or a safety message within an hour, from a phone, possibly on a degraded connection. Build that in: an editable site-wide banner, an alternative contact route, hosting that is not single-region, and a tested way to update the site when the office has no power.

The other calendar fact is seasonal demand. Winter, the cruise schedule out of PortMiami and the December art week bring a surge of international visitors on foreign SIM cards and foreign cards. That is the traffic your Spanish pages, your instalment options and your card risk rules are actually for.

A useful test before you sign off a Miami build: complete a purchase in Spanish, with a two surname name, a Colombian mobile number, and a card issued outside the United States. Most sites fail that run.
