Hupspot Guide to Payment Gateways
Choosing the right payment gateway is vital for any business using Hubspot to manage leads, quotes, and customer relationships. A secure, reliable gateway helps you collect payments online, build trust with buyers, and reduce friction at checkout so more deals close successfully.
This guide walks through what a payment gateway is, how it works, and how to compare providers based on security, cost, and ease of use.
What Is a Payment Gateway?
A payment gateway is a service that securely transfers payment data from your website, app, or invoicing tool to the financial institutions that process the transaction.
It acts like a digital point-of-sale (POS) terminal:
- Collects card or digital wallet details from the buyer.
- Encrypts and transmits that data to the payment processor and banks.
- Returns an approval or decline message in seconds.
- Helps protect you and your customer from fraud.
Many gateways can also handle recurring billing, refunds, and support for multiple payment methods such as credit cards, debit cards, and wallets.
How a Payment Gateway Works Step by Step
Behind every smooth online transaction is a technical flow that needs to be secure and fast. Here is a simplified version of what happens when a customer pays online.
1. Customer Enters Payment Information
The buyer chooses a product or service and moves to checkout, then enters card details or selects a digital wallet. The gateway securely captures this data on a payment form or hosted page.
2. Data Is Encrypted and Sent
The gateway encrypts the sensitive information so it cannot be read if intercepted. Then it sends the data to the payment processor, which communicates with the card networks and banks.
3. Authorization Request
The issuing bank (the bank that issued the customer’s card) checks:
- Is the card valid?
- Are there enough funds or credit?
- Is there any sign of fraud?
If everything looks good, the issuing bank sends back an authorization approval. If not, it returns a decline message.
4. Response to Merchant and Customer
The gateway receives the bank’s response and passes it back to the website or app. The buyer sees a confirmation message or is asked to try another payment method.
5. Settlement of Funds
Later, usually in daily batches, the transaction is settled. Funds move from the issuing bank to the acquiring bank (the merchant’s bank) and then to the merchant account.
Key Features to Look For in a Gateway
When you manage your sales funnel, contacts, and quotes on a CRM like Hubspot, your payment gateway should be just as reliable. Focus on features that support security, flexibility, and growth.
Security and Compliance
- PCI DSS compliance: Confirm that the provider meets Payment Card Industry Data Security Standards.
- Tokenization: Sensitive card data is replaced with tokens, reducing the risk of exposure.
- Encryption: End-to-end encryption keeps data secure in transit.
- Fraud tools: Risk scoring, address verification (AVS), and 3D Secure for extra authentication.
Supported Payment Methods
Your buyers expect choice. Look for gateways that can accept:
- Major credit and debit cards (Visa, Mastercard, American Express, Discover)
- Digital wallets (Apple Pay, Google Pay)
- Buy now, pay later options (where available)
- Bank transfers or ACH in markets that use them
Global Reach
If you sell internationally, your provider should support:
- Multiple currencies and currency conversion
- Localized payment methods for different countries
- Compliance with regional regulations
Ease of Integration
Many modern gateways offer:
- Prebuilt checkout pages and forms
- Plugins for popular ecommerce platforms
- Clear developer documentation and APIs
This helps you launch faster and maintain less custom code over time.
Transparent Pricing
Gateway pricing structures vary. Common models include:
- Flat-rate pricing: A fixed percentage plus a small fee per transaction.
- Interchange-plus: Interchange cost plus a consistent markup.
- Tiered pricing: Transactions grouped into qualified and non-qualified tiers.
Compare setup fees, monthly fees, chargeback fees, and refund policies before you commit.

3. Compare Pricing and Contracts
Gather quotes or use calculators from several providers. Pay attention to:
- Per-transaction fees
- Monthly minimums
- Chargeback and refund fees
- Contract length and cancellation terms
4. Evaluate Integration and Support
Ask these questions:
- Is there a plugin or direct integration for your ecommerce or billing system?
- How good is the documentation for developers?
- What support channels are available (chat, phone, email) and during which hours?
5. Test Before You Commit Fully
Use sandbox environments or test modes to simulate payments. Verify:
- Checkout speed and user experience
- Error messages and decline handling
- Data exports and reporting quality
Connecting Payment Data to Your CRM
Once your gateway is running, connect payment data with your CRM and sales tools so your team has a complete picture of each customer’s lifecycle.
Benefits of tight data alignment include:
- Clear visibility into which leads turned into paying customers.
- Accurate revenue reporting by campaign or sales rep.
- Automated follow-ups after purchase, renewals, and upsells.
