Payment Gateways for Tampa Ecommerce Sites

When a Tampa buyer types their card number into your WooCommerce checkout, three systems coordinate:

1. The gateway (Stripe, Square, Authorize.net) encrypts the card data, authorizes the charge with the card network, and returns a yes/no.
2. The merchant processor (often the same company, sometimes separate) settles the funds and deposits them to your bank.
3. Your bank account receives the deposit, usually 1-3 business days later.

Modern gateways (Stripe, Square) bundle gateway + processor. Older models (Authorize.net) separate them — you have a gateway and a separate merchant account at a bank. The bundled model is simpler; the separated model can be cheaper at high volume.

Square makes the most sense for businesses that already use Square for in-person sales — a Tampa cigar lounge, a boutique fitness studio, a coffee shop with retail, a med spa with a product line. The advantage is unified inventory and customer data across online and in-person.

Pricing. 2.6% + 10¢ for online card-not-present transactions on the Square Online platform. 2.9% + 30¢ for invoices. In-person POS is 2.6% + 10¢. No monthly fee on the free tier.

Strengths:

• Inventory sync between online store and in-person POS. Sell a candle at your Hyde Park storefront, the online stock count updates automatically.
• Customer records unified across channels. A buyer who bought in-store appears in your online customer list with their preferences.
• POS hardware is excellent and reasonably priced (the Square Stand, Square Terminal, Square Register).
• Same-day deposits available for a fee.
• Strong customer support, including phone.
• Square Loyalty program is straightforward and works across channels.

Weaknesses:

• WooCommerce integration is functional but less polished than Stripe’s. Some store features (especially around subscriptions and complex variations) work better with Stripe.
• No native Apple Pay/Google Pay express button on WooCommerce — possible with a workaround, but not default.
• Online checkout is less customizable than Stripe.
• Square Online (their hosted ecommerce platform) is a separate thing from “Square as a gateway on WooCommerce.” We’re talking about the latter here.

Best for: Tampa businesses with a real physical presence who want unified online + in-person commerce. Coffee shops, breweries, boutiques, salons with retail, fitness studios. Pairs well with the product page and checkout patterns we standardize on.

Authorize.net is the OG gateway. Owned by Visa. Slower-moving, less polished than Stripe, but still relevant in two scenarios.

Pricing. Authorize.net itself is a gateway — you need a separate merchant account from a bank or ISO. Gateway fee is typically $25/mo + 10¢ per transaction. Merchant account fees vary by acquirer; usually 2.5%-2.9% + 25-30¢, sometimes lower for high-volume B2B.

Strengths:

• Many traditional merchant banks default to Authorize.net. If your bank already gave you a merchant account, this is likely the path.
• Supports recurring billing (CIM) and ACH transactions natively.
• Strong B2B fit — net-30 invoicing, purchase order workflows, customer information manager (CIM) for storing tokenized cards.
• Phone-based support and account managers.
• Wide acceptance for higher-ticket transactions ($1K+) where some processors get nervous.

Weaknesses:

• Older API, clunkier integrations. WooCommerce extension works but isn’t as smooth as Stripe.
• Apple Pay/Google Pay support is limited.
• Monthly gateway fee whether you transact or not.
• Less innovation, less roadmap. The product hasn’t changed materially in years.

Best for: Tampa B2B distributors, dental and medical supply, industrial parts, high-AOV retail, businesses with existing bank-issued merchant accounts. See B2B ecommerce in Tampa for the customer-side build.

The default payment configuration on a new build:

Primary: Stripe — handles card transactions, Apple Pay, Google Pay, and subscription billing.

Secondary: PayPal Checkout — appears as a button at the top of checkout. Captures the 20-25% of buyers who prefer it.

Optional add-ons:

• Stripe Klarna / Afterpay — if AOV is $100+ and the buyer demographic skews younger, BNPL lifts conversion 10-20%.
• ACH via Stripe — for B2B stores that want lower-fee bank-debit transactions on large orders.
• Authorize.net replacing Stripe — if the client already has a merchant account they want to keep.

This covers 90% of Tampa ecommerce use cases.

The headline rate isn’t the whole picture. Things that add up:

Chargeback fees. $15-25 per chargeback. A 0.5% chargeback rate on a $1M/year store is 50 chargebacks at $15 each = $750/year, plus the chargeback amount itself.

Refund fees. Stripe and Square refund the transaction but keep the processing fee. So a refunded $100 sale cost you $3.20 in fees that don’t come back. Build this into your refund policy thinking.

International transaction fees. Cards issued outside the US carry an extra 1% on Stripe. Worth knowing if you ship internationally.

Currency conversion. If you accept multiple currencies, conversion adds 1-2%. Most Tampa stores transact in USD only; this is minor.

Monthly minimums. Most modern gateways have none. Some older merchant accounts (especially through banks) have a $25-$50/mo minimum in fees regardless of volume. Read the contract.

Three questions narrow it down:

1. Do you have a physical Tampa storefront with in-person sales?

– Yes → Square (unified inventory and customers) – No → continue

1. Are you primarily B2B with net-30 terms, POs, or an existing bank merchant account?

– Yes → Authorize.net (or Stripe + a B2B extension if you want modern UX) – No → continue

1. Default answer: Stripe primary + PayPal secondary.

BNPL providers (Klarna, Afterpay, Affirm, PayPal “Pay in 4”) aren’t payment gateways themselves — they layer on top of your existing gateway. The buyer chooses BNPL at checkout, the BNPL provider pays you in full, and they collect installments from the buyer over 4-6 weeks.

Fees: Typically 4-6% per transaction, paid by you. Higher than a standard card.

Worth it when:

• Your AOV is $100+
• Your buyer demographic skews under 40
• You’re in CPG, fashion, beauty, fitness, supplements, or home goods
• You can absorb a 4-6% take rate or have built it into pricing

Not worth it when:

• AOV is under $50 (BNPL friction isn’t worth the small ticket)
• Premium luxury positioning (clashes with installment psychology)
• B2B (where net-30 invoicing replaces it)

We integrate via Stripe’s native BNPL options (Klarna and Afterpay are both Stripe-integrated now) or via standalone WooCommerce extensions for Affirm.

A frequently overlooked piece of gateway selection: how the money flows into your books.

Stripe. Daily payout, single line item per payout in your bank. Stripe dashboard shows fees, refunds, chargebacks separately. Easy QuickBooks Online integration via Synder or the native Stripe integration. We help wire this on launch.

Square. Daily payout, similar structure to Stripe. QuickBooks integration is native and clean.

Authorize.net. Payout flow depends on your merchant acquirer. Reconciliation is more manual — you’re matching gateway deposits to bank deposits, often with a day’s lag.

PayPal. Payouts sit in PayPal’s wallet until you transfer to your bank. Reconciliation is its own thing — PayPal fees, refunds, and chargebacks live in a separate ledger from your card processor.

For a single-gateway store, reconciliation is easy. For a multi-gateway store (Stripe + PayPal + Square), the accountant earns their fee. Worth knowing on day one, not month nine.

If you’re building a new Tampa ecommerce store, payment gateway setup is part of our standard WooCommerce build — we configure, test, and tune the gateway as part of the project.

If you have an existing store and want a gateway review (paying too much in fees, mobile conversion suffering, gateway-related dispute issues), the $500 ecommerce audit covers it.
