Emeka owns a supermarket in Owerri. On a busy Saturday afternoon, every card terminal in his shop started saying “transaction failed”. The queue grew, customers put their baskets down and walked out, and Emeka lost about an hour of sales. He phoned his bank, and the bank said, “Call your PoS provider.” The PoS provider said, “There is a network problem with the switch.” Emeka asked me afterwards, “Who is actually in charge of my money between my till and my bank account?” It was a fair question, and the honest answer is: several companies, and most shop owners have never heard their names.

One of those names is a company you have almost certainly used without knowing it. Interswitch and Verve sit behind many of the cards, terminals and bill payments that Nigerians use every day. You may have a Verve card in your wallet right now. You may have paid a school fee or bought electricity through a service built on the same rails. I set up POS systems and payment flows for shops, pharmacies and restaurants in Abuja and Lagos, and understanding these rails has saved my clients many hours of confusion.

In this article I explain in plain language what a payment switch is, what Interswitch and Verve do, how one card payment travels from your till to your bank, why payments fail, and what you can do about it. Facts from public reports or company statements are marked “reported” or “publicly stated”. The details of fees and rules change, so please check the official pages before you make decisions.

Interswitch and Verve in plain English

Let us start with the simplest picture. Imagine a big roundabout in Lagos where roads from many towns meet. Cars enter, the roundabout sends each car onto the right road, and everybody arrives. A payment switch is a roundabout for money messages.

What is a payment switch?

A payment switch is a technology company that connects banks, terminals, merchants and payment services so they can talk to one another. When a customer of Bank A taps a card at a shop whose terminal belongs to Provider B, the message goes through a switch, which routes it to Bank A, asks “Can this customer pay ₦25,000?”, and returns the answer in seconds. Without switches, every bank would have to connect separately to every other bank and every terminal. It would be slow, expensive and messy.

Why Nigeria needed a switch in the first place

Think back to the early days of ATMs in Nigeria. Many people remember queueing at their own bank’s machine because using another bank’s ATM was difficult or expensive, or simply not possible. Each bank had built its own island. A shared switch meant a customer of one bank could use another bank’s machine, and later a shop could accept a card from any bank on one terminal. That single change made cards far more useful. It is a good reminder that a simple, boring connection can open a whole market.

The Interswitch story, as publicly reported

Interswitch is a Nigerian company that was founded in 2002 by Mitchell Elegbe, who has been widely reported as its founder and chief executive. It began with a simple, powerful job: connecting banks so that a customer of one bank could use another bank’s ATM. Over the years it grew into a wider payments and digital commerce company, serving banks, businesses, governments and consumers. In 2019 Visa was reported to have invested about $200 million for a minority stake, in a deal that valued the company at more than $1 billion. That made it one of the early Nigerian tech unicorns, though the exact terms are for the companies to state.

Verve, Quickteller and the other products

Verve is the card scheme (the brand and rulebook behind a card) owned by Interswitch, and it is a Nigerian-built alternative to the big global names. Many Nigerian bank debit cards carry the Verve logo, sometimes alongside Visa or Mastercard. Quickteller is a well-known consumer and business service for bill payments, transfers and airtime. There is also an online payment gateway for merchants, tools for collections by governments and large billers, and services for banks and PoS providers. The company has also publicly described efforts to push Verve into other African markets.

The payment rails map: who does what when you pay

When a payment goes wrong, the hardest part is knowing whom to call. So let me draw the map of who does what. It will help you ask the right question the first time.

The four parties in a card payment

There are four main parties. The cardholder is your customer. The issuer is the customer’s bank, which gave her the card and holds her money. The merchant is you. The acquirer is the bank or payment company that serves you, gives you your terminal or gateway and receives money on your behalf. Between them sit the switch and the card scheme. Each takes a small fee for the work, and each can be a point of delay.

Switches, schemes and gateways: three different jobs

People mix these up, so here is a simple rule. A switch moves the messages. A scheme sets the rules and brand of the card, such as Verve, Visa or Mastercard. A gateway is the tool that lets a website or app talk to the system. A company can do more than one of these jobs. For example, Interswitch acts as a switch and runs the Verve scheme, and it also offers a gateway. Paystack and Flutterwave, which I describe in my articles on the Paystack story and on Flutterwave explained, are gateways and payment platforms that connect to banks and switching services behind the scenes.

NIBSS and instant bank transfers

Not every payment is a card payment. When you send a bank transfer from your phone and it arrives within seconds, you are usually using a system run by NIBSS, the Nigeria Inter-Bank Settlement System, which is jointly owned by the Central Bank of Nigeria and the banks. NIBSS also runs the BVN system and other national payment services, and it is a separate organisation from Interswitch. Nigeria has several parties in the rails, not one, which is normal for a large payment system.

Follow one ₦25,000 payment from your till to your bank

Let us make this real. Amaka buys goods worth ₦25,000 at Emeka’s supermarket and pays with her Verve card. Here is what happens, in plain steps. The whole thing usually takes a few seconds.

The journey, step by step

1. The cashier enters ₦25,000 and Amaka inserts or taps her card.
2. The terminal reads the card and asks for her PIN, then sends an encrypted request to the provider that manages the terminal.
3. The provider sends the request to a switch, which recognises the card scheme and routes it to Amaka’s bank, the issuer.
4. Amaka’s bank checks her balance, limits and fraud rules, and replies “approved” or “declined”.
5. The answer travels back along the same path, and the terminal prints a receipt.
6. Later, in a process called clearing and settlement, the money moves between the banks, and the acquirer pays Emeka, minus fees, usually on the next business day or on the schedule in his contract.

Where time and money leak

Delay can happen at every step. The terminal may lose the network. The provider’s server may be slow. The switch may have a problem, or the issuer’s system may time out even though the money was actually taken. This last case is the scary one: the customer’s bank has debited her, but the terminal never got the “approved” message. The customer sees “failed”, the bank sees “success”. The fix is a reversal, which returns the money automatically after checks. The rules say banks and providers must handle such cases within set time limits, and you can read the current rules on the CBN’s official website.

Settlement: why the money is not in your account yet

A customer’s payment approval is instant, but the actual movement of money between banks happens later, in batches. This is called settlement. Your provider then pays you according to your agreement: some pay the next business day, some pay faster for an extra fee, and weekends and public holidays can add time. So a Saturday sales total may reach your bank on Monday or Tuesday. If you have to pay a supplier on Monday morning, plan for that. Keep a small cash buffer, and ask your provider for the settlement calendar, including how it treats holidays such as Christmas, Eid and Easter.

Why ordinary payments fail

• Customer side: wrong PIN, insufficient funds, daily limits on the card, or a bank fraud rule that blocked the payment.
• Terminal side: weak network, low battery, old software or a damaged card reader.
• Provider or switch side: downtime, heavy traffic on salary days and festive seasons, or upgrades.
• Issuer side: the customer’s bank is slow or has an outage.

When Emeka’s terminals all failed together on that Saturday, the likely cause was not his shop. It was somewhere upstream, and the only thing he could do was tell customers honestly, keep a backup payment option ready and record every failed attempt. We fixed that with a small plan I describe later.

What “pending”, “failed” and “reversed” really mean

Payment screens use a few status words, and each one tells you what to do. Successful means the issuer approved and the money is on its way to you, so you can release the goods. Failed means the payment was declined, and no money should leave the customer’s account. Pending means nobody is sure yet, so wait and do not release goods or ask the customer to pay again until you know. Reversed means the money was returned to the customer after a problem. Many disputes start because a cashier treats “pending” like “successful”. A simple rule on the wall, “No goods on pending”, prevents a lot of losses.

Verve, Visa, Mastercard and AfriGo: what merchants should know

If you accept cards, you will meet more than one card brand. Knowing the differences helps you avoid a very common complaint: “Your machine does not accept my card”.

Verve in everyday use

Verve is widely used across Nigerian banks, and many customers, especially those with basic bank accounts, carry it. For in-person payments on PoS terminals, Verve is generally well supported in Nigeria. Your terminal provider should confirm that Verve is enabled on your terminal, in the same way as other brands. Ask them to show you a test transaction with a Verve card before you sign.

Global schemes and international cards

Visa and Mastercard are global card schemes. Their cards work in many countries and are widely accepted for online payments abroad. Verve has made efforts, including reported partnerships with global networks, to widen its acceptance beyond Nigeria, but for international online shopping, customers still often use Visa or Mastercard products. If you sell to the diaspora or foreign customers, test your online checkout with foreign cards as well as with local ones. AfriGo, a national card scheme launched by the CBN and NIBSS in 2018, is another local option that you may see on some cards.

What to check on your terminal and website

For a physical shop, test every card type your customers carry: Verve, Visa, Mastercard, and contactless or tap cards. For an online store, check that your gateway lets Verve card holders pay, because a large share of Nigerian shoppers have one, and some checkout flows need extra steps such as a PIN or an OTP (a one-time code sent by SMS). Test at a slow network time as well. I once found a store where Verve payments failed only at night because a bank code arrived too late. The owner had never tested at night.

What the Interswitch story teaches business owners

You may never run a payment switch. But the choices behind this company hold ideas that any business can use.

Build the boring infrastructure that everyone needs

Interswitch grew by solving a shared problem: banks needed to connect. It did not chase the newest fashion. It built a service that many others depended on. In your own market, ask what “pipe” other businesses need. For a small team in Abuja, that might be reliable delivery for online sellers, or a clean school fees system for private schools. Boring and necessary beats exciting and optional.

Make connection easier for everyone

A switch becomes more valuable with every new bank and merchant that connects. That is called a network effect: the more users, the more useful the service. If you run a marketplace, a franchise or a group of shops, think about how each new member makes the whole group stronger, not just bigger. Good systems reward everyone who joins.

Trust and regulation are part of the product

Payments are regulated for good reasons. Companies in this business spend a lot of time on licences, security standards and reports. When you handle money in any way, treat compliance as part of your service, not a paperwork burden. Keep your registrations up to date, use official channels, and keep proper records.

Partner with giants without losing your identity

The reported investment from a global payments network suggests that Nigerian infrastructure can work with global players and still keep its own identity. In small business terms, you can partner with a big supplier or platform and still keep your own brand and customer relationship. Do the partnership, but keep your list, your brand and your records.

Play the long game

Infrastructure businesses rarely win overnight. They earn trust one working day at a time, and they get paid because others depend on them. In small business terms, the long game means answering every complaint properly, keeping your promises on delivery dates and paying your suppliers on time. Reputation compounds like interest. A shop in Kaduna that has never failed a customer in ten years does not need to shout. The neighbourhood does it for her.

A client-style story. Tunde runs three pharmacies in Lagos. His terminals came from three different providers, one for each branch, because each branch manager had chosen his own. At month end nobody could match the card sales. We moved all three branches to one provider with one report and connected the terminal totals to his POS software. The first month showed a gap of ₦86,000 that came from two manual entries and one duplicate. He said, “I did not know I had three problems until I had one report.” Standard rails and standard reports make errors visible.

The costs behind a card payment

You pay a fee when a customer pays by card. That fee pays for a chain of services, and understanding the chain makes negotiation easier.

Where the fee goes

The fee you pay is often called a merchant service charge or merchant discount rate. In general, it covers the customer’s bank for the risk and service of the card, the provider that serves you, the switch that routes the payment and the card scheme. How it is shared depends on rules, contracts and the type of card, and regulators can set caps. I will not give you a single universal rate, because it depends on your provider, your volume and the rules of the day.

A worked example with an assumed rate

Suppose your agreed rate is 0.8% on card sales, and you sell ₦2,000,000 by card in a month. The fee is ₦16,000. If your net profit margin is 10%, your profit on those sales is ₦200,000, so the card fee takes 8% of that profit. That is not a disaster, but it is not a rounding error either. If you also lose ₦40,000 a month to failed payments and unmatched records, the “hidden” cost is bigger than the fee. That is why records and reliability matter as much as the rate.

Chargebacks and disputes on card payments

A chargeback happens when a customer disputes a card payment with her bank, and the bank pulls the money back from the merchant while the case is checked. For a shop, common causes are a customer who does not recognise a charge, a claim that goods never arrived, or a genuine mistake such as a double charge. The card scheme’s rules decide how long you have to respond. Keep your receipt, order record and delivery proof for at least six months, and read your provider’s dispute rules before you sign. Strong records win most disputes, and weak records lose them.

How to negotiate and compare

Ask each provider for the full price list in writing: fee per transaction, any cap, monthly or terminal fees, and settlement times. Ask about the cost of chargebacks and the time allowed to respond. Compare the total cost for your own volume, not just the headline percentage. A provider with a slightly higher fee but faster settlement and better support may be cheaper overall than one with a low fee and slow, unclear reports.

Card, transfer, QR, USSD or online checkout: which should your shop use?

Every business in Nigeria should think about a mix of ways to get paid. Each method rides on different rails and has a different feel for the customer and a different risk for you.

Card on a PoS terminal

This suits shops with a counter: supermarkets, pharmacies, restaurants and salons. It gives instant confirmation on the terminal, a receipt and a record. The cost is the merchant fee and the terminal cost, and it depends on network and power. It is the closest thing to cash for the customer who has a card.

Bank transfer

Transfers are hugely popular. They are quick, and there is no terminal cost. The risk is proof: fake alerts and screenshots. A safe habit is to confirm the money in your own bank app or dashboard, and to ask for the transaction reference or session ID (a unique code for that transfer). Using a dynamic account number that is created for each order can make matching much easier.

QR codes, USSD and online checkout

QR codes let a customer scan and pay from her banking app, without typing an account number. USSD (dial-code) payments work even without data, which is helpful for customers with basic phones or weak networks. Online checkout, through a gateway, suits websites and apps. For a business that sells both in person and online, combining methods gives customers choice and gives you backup when one rail is down.

Proof of payment and daily reconciliation

Reconciliation is a long word for a simple habit: matching what your records say with what your bank and providers say. It is the single best defence against lost money in a shop that takes cards and transfers.

References, session IDs and receipts

Every payment leaves a trail. A card payment has a terminal receipt with a reference number, and your provider’s report lists it. A bank transfer has a session ID or transaction reference. An online payment has a gateway reference. Train your staff to ask for and note the reference when a customer says “I have paid”. If a dispute comes, the reference lets your provider or bank trace the payment quickly. Without it, everyone is guessing.

A ten minute daily routine

1. At closing time, print or download the terminal or gateway report for the day.
2. Compare the card and transfer total with the total in your sales system or ledger.
3. List any difference and circle the likely cause: failed payment, manual entry, refund or duplicate.
4. Check the next morning that the settlement from your provider matches the previous day’s report, less fees.
5. Record any open dispute, with the customer name, amount, reference and date.

This routine takes ten minutes for a small shop. It catches mistakes when they are small. A supermarket with several tills or a restaurant with many waiters needs software to do it automatically, and that is where a proper POS system helps. You can see how I set that up for different kinds of business in my pages on supermarket POS software, pharmacy POS software and restaurant POS systems.

Handling disputes and reversals calmly

When a customer says she was debited but the terminal said “failed”, do not argue. Take her phone number and the time and amount of the attempt, keep the failed receipt, and check your provider’s report. Tell her that most such cases are reversed by the banks within the time set by the rules, and give her a follow-up time. If it is not reversed, help her raise it with her bank and give them your terminal details. A shop owner who helps calmly keeps the customer and the reputation.

Risks to plan for in the rails

The rails are strong, but they are not perfect. I do not say this to scare you. I say it because a calm business prepares. Here are the risks I see most often.

When the network goes down

Outages happen at banks, switches, providers and telecom networks. They cluster at busy times: month end, salary days, festive seasons and big sales days. When the terminals fail at once, do not blame your staff. Switch to your backup: a bank transfer with a dynamic account, a QR code, or a second provider’s terminal. Put a small sign near the till that says which options are available today. Customers are patient when they see a plan.

Card fraud, skimming and social tricks

Fraudsters use stolen cards, cloned cards and clever stories. Watch for people who try many cards, who rush you, or who ask you to “refund” a payment to a different account. Never refund to a different method than the original payment without checking. Keep your terminals in view, do not let strangers touch them, and report any suspicious device tampering to your provider. For shops with cash and expensive stock, a camera over the till area is also worth the cost.

Depending on one provider or one rail

Concentration risk means putting everything in one basket. If all your card sales run through one provider and it has a problem, your business slows down. If all your online sales run through one gateway, a review or outage stops them. Reduce risk by keeping at least one alternative ready, such as a second provider for busy shops or a backup gateway for online stores. The extra cost is small compared with a lost weekend.

Why Interswitch and Verve matter in Nigeria right now

The payment rails are not glamorous, but they shape what your customers can do and what your business can offer. Three changes make them more important each year.

Interoperability is why any-bank payments work

A customer of any bank can pay at a shop whose terminal comes from any provider, and it works in seconds, because of shared rails and rules. That is not true everywhere in the world. It took years of work by the CBN, banks and companies like Interswitch and NIBSS. For you, the benefit is simple: you do not need a separate machine for each bank. Do not take it for granted, and do not forget who keeps it running.

Nigerian-built rails and trust

Local schemes and switches mean that a lot of Nigerian payment traffic can be handled at home, with local knowledge and local support. That matters for speed, for cost and for resilience. It also means that when you have a problem, there are Nigerian teams you can reach. Many Nigerian founders now build on these rails, and I explain how developers use the newer layers in my guide to fintech APIs in Nigeria.

New layers on top of old rails

Agent banking, gateways and mobile wallets ride on the same foundation. You can see how one of the biggest agent networks grew in my article on Moniepoint and the rise of agent banking in Nigeria. Each new product uses the rails in a slightly different way, and each adds its own fees and support paths. The more you understand the base, the easier it is to judge each new offer.

What may come next

Nigeria’s payment system keeps evolving. QR code payments, mobile wallets, links between local and international networks, and new ways for apps to connect to bank data are all being discussed and built. I cannot tell you which will win, and some ideas will fade. What I tell my clients is to follow the CBN’s official announcements, keep their systems flexible, and avoid signing very long contracts that lock them into one method. A flexible business can adopt the next good tool quickly.

A 30 day payments health check for your business

Use this plan to turn the ideas in this article into action. It needs no special skill, only a notebook and a bit of time each week.

Week by week

Write a one page payment guide for staff

Write down, on one page, what to do when a payment fails, when a customer shows a screenshot, when all terminals go down, and who to call at each provider. Add phone numbers and account details for support. Stick it beside the till. Emeka, the supermarket owner in my opening story, did this and now his cashiers handle a system outage in minutes instead of half an hour.

Key takeaways

• Interswitch and Verve are Nigerian-built payment infrastructure: a switch that routes payments, and a card scheme used on many local debit cards.
• Interswitch was founded in 2002 by Mitchell Elegbe and was reported to have received a $200 million investment from Visa in 2019, valuing it at over $1 billion.
• A card payment involves a customer, her bank, your provider, a switch and a scheme. Knowing who does what helps you call the right party.
• Failed payments have many causes. Record every failure, keep receipts and never release goods on a screenshot.
• Test every card brand you accept, including Verve, on your terminal and your website, and at different times of day.
• Compare providers on total cost for your volume: fees, settlement time, support and reports, not just the headline percentage.
• Reconcile daily. Ten minutes at closing time catches errors that would otherwise cost you thousands of naira.
• Keep a backup payment method or provider so that one outage does not stop your shop.
