What Are the Disadvantages of Using a Third-Party Payment Gateway?
Third-party payment gateways make it easy to start accepting payments quickly, but that convenience comes with trade-offs that become more noticeable as a business scales. Understanding these disadvantages — rather than discovering them after they've already caused a problem — helps businesses decide whether a third-party gateway is still the right fit as they grow.
Key Takeaways
Third-party payment gateways can introduce higher costs, security dependencies, and reduced control compared to direct payment processing relationships.
Businesses are exposed to the third-party provider uptime, policy changes, and account review decisions, which they can't directly control.
Complex integration requirements and customer friction (redirects, unfamiliar checkout branding) can affect conversion rates.
Regulatory compliance responsibilities don't fully disappear just because a third party handles processing — businesses still carry some obligations.
Direct or first-party payment gateway options exist specifically to address these limitations for businesses that have outgrown third-party solutions.
Higher Costs Over Time
Third-party gateways typically charge a percentage-based fee per transaction, which can add up significantly for high-volume businesses. Unlike a direct merchant account relationship, where fees may be more negotiable at scale, many third-party providers apply relatively fixed fee structures regardless of a business's transaction volume, making them proportionally more expensive as a business grows.
Security Vulnerabilities and Shared Risk
While reputable third-party gateways maintain strong security standards, businesses are ultimately trusting an external party with sensitive transaction data. Any security incident on the provider's side — a data breach, a service vulnerability — can directly affect the merchant's business and customer trust, even though the merchant has no direct control over the provider's internal security practices.
Dependence on Provider Uptime
When a business relies entirely on a third-party gateway, any outage on the provider end directly stops the business from processing payments. This dependency is often invisible until it causes a problem — a payment outage during a high-traffic sales period, for example, can mean significant lost revenue that the merchant has no way to prevent or route around.
Reduced Control Over Transactions
Third-party gateways set their own rules around transaction holds, account reviews, reserve requirements, and dispute handling. A business can find funds held or an account under review based on the provider internal risk algorithms, sometimes with limited visibility into why or how long the review will take. This lack of control can create serious cash flow uncertainty, particularly for businesses in higher-risk categories that are already subject to closer scrutiny.
Complex Integration Requirements
While many third-party gateways market themselves as easy to integrate, more advanced use cases — custom checkout flows, multi-currency support, subscription billing logic — often require significant development work to properly integrate with a third-party provider's API and constraints, partially offsetting the "quick setup" advantage that draws businesses to third-party solutions in the first place.
Potential Customer Frustration
Some third-party gateways redirect customers away from the merchant own website to complete payment, which can introduce friction, reduce trust at the point of purchase, and increase cart abandonment compared to a fully embedded, on-site checkout experience.
Regulatory Compliance Challenges
Using a third-party gateway doesn't fully remove a business compliance obligations. Depending on how payment data flows through the integration, merchants may still carry PCI DSS responsibilities, and they remain responsible for how they represent transactions to customers, handle refunds, and manage data privacy — compliance work that can be easy to underestimate when a third party is technically "handling payments."
Why Some Businesses Move Toward First-Party Payment Processing
Given these disadvantages, businesses — particularly as they scale — often look for alternatives that give them more direct control. This is where B2B direct, first-party payment gateway solutions become relevant: rather than routing every transaction through a third-party intermediary with its own risk rules and fee structure, a first-party setup gives a business a more direct processing relationship, often with more negotiable fees, more transparency around account holds, and more control over the checkout experience. Webpays, among other providers, positions itself around offering this kind of more direct payment relationship for businesses that have outgrown the constraints of third-party gateways.
When Third-Party Gateways Still Make Sense
To be fair, third-party gateways aren't wrong for every business. They make sense for:
Early-stage businesses that need to start accepting payments quickly without significant upfront setup
Low-volume businesses where percentage-based fees don't yet represent a meaningful cost
Businesses that don't have the technical resources for a more complex direct integration
Situations where the third party brand recognition (PayPal, for example) actively helps customer trust at checkout
The disadvantages become more significant as transaction volume grows, as the business enters higher-risk categories, or as the need for a fully custom checkout experience increases.
A Practical Way to Evaluate the Trade-Off
Calculate actual fee cost at current and projected volume — not just the advertised rate
Assess how much control you need over transaction holds, reserves, and dispute handling
Review your uptime tolerance — how much revenue would a processing outage cost you during peak periods?
Consider your checkout experience needs — does customer friction from redirects matter for your conversion rates?
Evaluate your compliance exposure — confirm exactly what PCI and regulatory obligations remain with you regardless of which gateway you use
The Bottom Line
Third-party payment gateways solve a real problem — fast, low-friction access to payment processing — but that convenience comes with cost, control, and dependency trade-offs that grow more significant as a business scales. For businesses that have outgrown these limitations, first-party or direct payment gateway solutions offer an alternative built specifically to address them.

Frequently Asked Questions
Is a third-party payment gateway ever a bad choice?
Not inherently — it depends on business stage and needs. Early-stage or low-volume businesses often benefit from the speed and simplicity of third-party gateways, while the trade-offs become more significant as volume and complexity grow.
Do third-party gateways remove all compliance responsibility from merchants?
No. Merchants typically retain some PCI DSS and regulatory obligations depending on how payment data flows through the integration, even when a third party handles the core processing.
What's the main difference between a third-party and a first-party payment gateway?
A third-party gateway acts as an intermediary with its own fee structure, risk rules, and account review processes. A first-party (direct) gateway gives a business a more direct processing relationship, typically with more control and negotiable terms, especially at higher transaction volumes.
How do I know if my business has outgrown a third-party gateway?
Common signs include rising per-transaction costs at scale, frequent account holds or reviews affecting cash flow, or a growing need for a custom checkout experience that the third-party provider can't fully support.
Can switching from a third-party to a first-party gateway affect my checkout experience?
It can improve it, since first-party setups often allow for a fully embedded, on-site checkout rather than redirecting customers to a third-party branded page — though the actual improvement depends on the specific implementation.
