Paystack vs Flutterwave vs Interswitch: Best Payment Gateway for WordPress in Nigeria
Why Your Gateway Choice Matters
Your payment gateway does more than process checkout transactions. It’s the difference between completing a sale and watching customers abandon their carts in frustration.
In Nigeria, this matters even more. The Central Bank of Nigeria (CBN) recently fined Paystack ₦250 million for regulatory issues. Flutterwave powers payments across 14 African markets. Interswitch has operated for over 20 years. Each gateway has strengths and weaknesses that directly affect your business.
Choosing the right payment gateway for WordPress in Nigeria involves understanding how each platform addresses real-world challenges, such as failed transactions, settlement delays, and regulatory compliance. This article breaks down what you need to know about integrating Paystack, Flutterwave, and Interswitch with WordPress, focusing on what actually works in the Nigerian market.
The Nigerian Payment Gateway Reality
Nigeria’s digital payment landscape has undergone significant changes. The CBN’s push for financial inclusion, combined with the widespread adoption of smartphones, has created a competitive gateway market.
What matters most for business owners choosing a payment gateway for WordPress in Nigeria? Transaction success rates. Failed payments aren’t rare here. Network issues, insufficient card limits, and banking system quirks result in a significant percentage of transactions failing on the first attempt.
Compliance is equally important. The CBN is watching fintech companies closely. Choosing a gateway with solid regulatory standing protects your business from unexpected disruptions.
For WordPress users specifically, integration quality determines how quickly you go live and how smoothly payments work afterward.
Meet the Big Three
Paystack
Paystack launched in 2016 and was acquired by Stripe in 2020 for over $200 million. They’re known for developer-friendly APIs, clean documentation, and responsive support.
The recent CBN fine for launching products without proper licensing raised compliance questions, but they remain one of Nigeria’s most popular gateways.
Flutterwave
Flutterwave positions itself as a pan-African payment platform operating across multiple countries in Africa. Their strength lies in versatility – they support a diverse range of payment methods, from mobile money to bank transfers.
If you need to accept payments across West Africa or handle multiple currencies, Flutterwave offers more options than competitors. WordPress integration requires more technical knowledge than Paystack, but their infrastructure handles volume well.
Interswitch
Interswitch is the veteran player, founded in 2002. They power Verve cards and operate Quickteller, making them deeply embedded in Nigeria’s financial infrastructure.
Their advantage is stability and institutional trust. Banks and large enterprises often prefer Interswitch due to their track record. WordPress integration isn’t as smooth as Paystack, but they handle large transaction volumes reliably.
What SMEs Need to Know
Transaction Success Rates and Reliability
A gateway with 2.5% fees but an 85% transaction success rate costs more than one with 3% fees and a 95% success rate.
Paystack generally performs well in Lagos and major cities, with strong infrastructure during peak periods. Some users report occasional issues with specific banks.
Flutterwave’s success rates vary depending on the payment method. Card transactions work well, but mobile money and bank transfers may experience delays due to network congestion.
Interswitch maintains consistently high success rates, especially for Verve cards. Their bank relationships result in fewer transaction rejections, although refund processing is sometimes slower.
Track your own success rates after going live. What works for one business might not work for yours.
Payment Methods and Local Support
Nigerian customers use multiple payment methods. Your gateway needs to support what your specific customers prefer.
All three gateways handle Mastercard, Visa, and Verve. The differences emerge with alternative payment methods.
Paystack offers bank transfers, USSD, and QR codes. Their bank transfer feature works particularly well for high-value B2B transactions where customers prefer direct debit.
Flutterwave supports the widest range of options: cards, bank transfers, USSD, mobile money (MTN, Airtel), and even cryptocurrency. If your customers are spread across multiple African countries, this versatility matters.
Interswitch focuses on cards and bank transfers. They pioneered Verve, so Verve transactions often process faster through Interswitch than through competitors. If most of your customers use Verve, this is a significant advantage.
WordPress Integration: Choosing Your Payment Gateway
Payment gateway integration for WordPress happens primarily through plugins. The quality of these plugins determines your setup experience and ongoing maintenance burden.
Paystack offers an official WooCommerce plugin that’s well-maintained and regularly updated. Installation is straightforward, even for non-developers. The plugin handles webhooks properly and includes good error handling.
Documentation is clear, and most WordPress customization needs are covered in their guides. When issues arise, their support team understands WordPress-specific problems.
Flutterwave offers a WooCommerce plugin; however, it requires more technical expertise to configure correctly. Setting up webhooks can be tricky, and you’ll need to understand concepts such as callback URLs and API keys.
If you’re comfortable with WordPress best practices, the Flutterwave plugin works fine. If you’re less technically inclined, you may need to hire assistance for the initial setup.
Interswitch plugin support is the weakest of the three. Their official plugin exists, but updates are infrequent. Many users rely on third-party plugins or custom integrations, which introduce maintenance concerns.
For businesses planning extensive customization with Elementor add-ons, Paystack offers the smoothest experience.
Plugin reliability matters as much as features. A plugin that breaks after WordPress updates creates serious problems. Paystack’s plugin stability is excellent. Flutterwave is generally reliable, but occasionally requires manual intervention. Interswitch plugins sometimes lag behind WordPress core updates.
Pricing Structure for Volume Businesses
Transaction fees directly impact your margins. Look beyond headline percentages to understand real costs.
Paystack charges 1.5% + ₦100 per transaction (capped at ₦2,000). The ₦100 fee is waived for transactions under ₦2,500, which helps with small purchases. International cards incur a 3.9% fee plus ₦100.
Pricing is simple and transparent with no hidden fees. Volume discounts require negotiation.
Flutterwave charges approximately 2.0% total for local NGN transactions (including platform fees), with a cap of ₦2,000, making them competitive for high-value transactions. International cards are charged a rate of approximately 4.8%. Pricing is subject to change, so please confirm the current rates on Flutterwave’s official pricing page before making a decision.
Interswitch pricing varies by business type and is subject to negotiation. Base rates are typically 1.5-2%, but large businesses can negotiate better terms. Setup fees may apply.
Settlement timing affects cash flow. Paystack settles T+1 (next business day). Flutterwave offers instant settlements for a fee; otherwise, it is T+1. Interswitch typically settles T+2.
For a business processing ₦5 million monthly, these differences matter. Calculate costs based on your expected volume and average transaction size.
Reporting and Business Management
Dashboard quality matters for daily operations.
Paystack’s dashboard is clean and intuitive. Exports work well, reports are comprehensive, and integration with accounting software is straightforward. Their API documentation is excellent for custom reporting.
Flutterwave’s dashboard handles complexity well, especially for multi-country or multi-currency operations. The interface offers more options and settings, which aid in complex operations but can overwhelm users of simple stores.
Interswitch’s dashboard is functional, but it is dated. Export options are limited, and generating custom reports requires extra clicks.
For WordPress membership sites with recurring payments, Paystack’s subscription management is most user-friendly.
Multi-Currency and International Payments
If you sell to customers outside Nigeria or frequently accept foreign cards, multi-currency support becomes critical.
Flutterwave leads here. They support over 150 currencies and 30 countries in Africa. If your WordPress use cases include cross-border sales, Flutterwave simplifies currency conversion and settlement.
Their exchange rates are competitive, and they handle the complexity of different regional payment methods.
Paystack supports multi-currency but focuses primarily on Nigeria and Ghana. International card acceptance works well, but they’re not built for pan-African operations like Flutterwave.
Interswitch primarily handles Nigerian transactions. International card acceptance works, but they’re not the best choice if international sales are a major part of your business model.
Compliance and Regulatory Standing
The CBN’s recent crackdown on fintech companies underscores the importance of regulatory compliance more than ever.
All three gateways hold the necessary licenses to operate in Nigeria. The differences are in how they handle new products and services.
Paystack’s ₦250 million fine was for launching a peer-to-peer payment feature without proper licensing. This doesn’t affect standard payment processing, but it highlights the regulatory risks in Nigeria’s fintech space.
Flutterwave has faced regulatory scrutiny in Kenya but maintains good standing with the CBN in Nigeria. Their size and funding provide some stability.
Interswitch’s 20+ year track record and close bank relationships give them regulatory advantages. They’re seen as part of Nigeria’s financial establishment rather than a disruptor.
For businesses in regulated industries (healthcare, finance), Interswitch’s stability might outweigh the convenience of newer platforms.
Support When Things Go Wrong
Payment issues need fast resolution.
Paystack offers email, live chat, and phone support for escalated issues. Response times are good (within hours), and their team understands WordPress-specific problems. Community forums are active with documented solutions.
Flutterwave provides email and phone support. Response times vary, sometimes taking a day for non-critical issues. Support is knowledgeable but less familiar with WordPress specifics.
Interswitch support is formal and process-driven. They’re reliable but slower. Urgent issues may take longer to resolve than those of competitors.
Paystack’s customer-facing error messages are clearest, reducing support tickets because customers understand what went wrong.
Starting Small? Here’s What Matters
If you’re launching your first WordPress website for business and processing your first online payments, your priorities differ from established SMEs.
Easiest Setup Process
Paystack wins here. Their WordPress plugin installs in minutes, configuration is intuitive, and you can process test transactions immediately. The documentation assumes you’re not a developer and explains each step clearly.
Account approval typically takes 1-2 business days if you have proper documentation (CAC registration, bank account, valid ID).
Flutterwave setup takes longer. The plugin configuration requires understanding webhooks and API keys. If technical terms intimidate you, budget for developer help.
Interswitch requires the most formal onboarding process. Approval can take a week or more, and setup often needs technical assistance.
Lowest Barriers to Entry
All three require business registration (CAC documents), a business bank account, and a valid ID.
Paystack’s approval is fastest and most flexible for small businesses. Flutterwave approves most legitimate businesses but asks more questions about your model. Interswitch prefers established businesses and may be less suitable for early-stage startups.
Pricing for Small Volumes
Paystack’s 1.5% + ₦100 is fair for small volumes. The per-transaction fee is a drawback for very small purchases, but it works fine for most products.
Flutterwave’s local fee is approximately 2.0% all-inclusive for NGN payments; however, please note that this does not include costs for instant settlements and add-on services.
Interswitch’s pricing isn’t transparent for small businesses and requires negotiation.
Simple WordPress Integration
For non-technical users, Paystack’s plugin is most forgiving. It works with popular WordPress themes out of the box and rarely conflicts with other plugins.
If you’re using page builders like Elementor or WooCommerce, Paystack requires minimal configuration, beyond simply entering your API keys.
Flutterwave and Interswitch plugins occasionally require adjustments to function properly with specific themes or page builders.
Support When You’re Learning
Paystack’s support team is patient with beginners and walks you through basic WordPress questions.
Flutterwave support requires more technical knowledge and sometimes uses jargon that can be confusing to non-technical users.
Interswitch support is professional but formal, better suited for businesses with dedicated IT staff.

- You can negotiate custom pricing
Questions to ask yourself:

Common Problems and Solutions
Failed Transactions
Failed payments frustrate customers and result in lost sales. Common causes include insufficient card limits, expired cards, network timeouts, and bank restrictions.
Paystack’s retry logic is most aggressive, automatically attempting failed transactions multiple times. Flutterwave lets you configure retry behavior. Interswitch is more conservative.
Improve success rates by offering multiple payment methods. If card payment fails, customers can try bank transfer or USSD.
Cart Abandonment
Poor checkout experience drives abandonment. Long load times, confusing payment pages, and a lack of trust signals can all hinder conversions.
Paystack’s checkout interface is the cleanest and loads fastest, which is important for WordPress speed optimization.
Test your checkout flow on mobile. Most Nigerian e-commerce happens on phones. A desktop-only optimized checkout kills conversions.
Disputes and Chargebacks
Customers sometimes dispute legitimate charges.
Paystack’s dispute management is straightforward, with clear evidence submission. Flutterwave’s process is similar but sometimes slower. Interswitch is more formal and documentation-heavy.
Prevent disputes by sending immediate order confirmations, providing clear tracking information, and making your refund policy easily accessible.
Using Multiple Gateways
Some businesses offer multiple payment options at checkout. This improves success rates but adds complexity.
If you choose this route, prioritize gateways based on their transaction success rates and customer preferences. Make your preferred gateway the default option.
This approach is most effective when you have technical resources available to manage multiple integrations. For most small businesses, focusing on a single gateway and optimizing it is more effective than spreading efforts across multiple gateways.
Beyond the Gateway
Your gateway is important, but not the only factor in payment success.
Website performance matters. Slow checkouts increase abandonment. Focus on WordPress speed optimization alongside gateway selection.
Security builds trust. SSL certificates are mandatory. Display trust badges. Use secure hosting.
Mobile optimization is critical. Test your entire checkout on a mobile phone with average Nigerian internet speeds.
Regular maintenance prevents problems. Set up a maintenance schedule that includes testing your payment gateway monthly.
Consider a website redesign if your current design makes checkout confusing.
Final Thoughts
No payment gateway is perfect. Each has trade-offs.
For most Nigerian businesses starting with WordPress, Paystack offers the best balance of reliability, ease of integration, and cost. If you need pan-African reach or diverse payment methods, Flutterwave’s complexity pays off. If you’re an established business prioritizing stability and regulatory compliance, Interswitch is a sensible choice.
Start with one gateway and commit to it for 3 to 6 months. Track transaction success rates, settlement times, and customer feedback to optimize your operations. Real data from your business beats theoretical comparisons.
Payment gateway integration isn’t a one-time decision. As your business grows, your needs change. Choosing the right payment gateway for WordPress in Nigeria requires staying flexible and being willing to switch if your current gateway stops serving you well.
