Inside Kola: how cross-border invoicing for Naija SMEs was built

If you're a Nigerian SME invoicing clients in dollars, you know the pain: you send an invoice through Gmail, wait three weeks for payment to hit your Paystack account, lose 3.5% to settlement fees, then spend another week moving money to your local bank while the naira weakens by 2% in the background. By the time you actually hold the cash, you've lost 6-8% to friction. That's the problem Ada and Tunde saw clearly in 2024, and it's what led them to build Kola.

Kola is a cross-border invoicing platform built specifically for Nigerian and African SMEs. It lets you issue invoices in USD, EUR, or GBP directly to your clients; get paid into a virtual account that settles instantly; and move money to your Naira account without the layered fees that make traditional payment processors look cheap. The founders spent six months talking to exporters, digital agencies, and SaaS founders across Lagos, Kano, and Accra before writing a single line of code. What they learned shaped every part of how Kola works today.

This is how they built it, what they learned, and why the timing—2025-2026—finally made this possible in Nigeria.

The problem was everywhere, but nobody was solving it right

Ada, who had previously worked in fintech operations at a Lagos-based payments company, noticed the pattern first. She was talking to a friend who ran a digital marketing agency in Yaba. The friend had three clients in the US, all paying between $5,000 and $15,000 per month. But the cash flow was a nightmare.

"She'd invoice them through Wave or Zoho Invoice," Ada recalls. "They'd pay into her Paystack account. Paystack takes 1.5% plus NGN 100. Then she'd move to her bank, and the bank takes another 1% on top. Then the naira would move 2-3% in the time it took for settlement. She was losing money on every transaction, and she couldn't even see where it was going."

Ada started asking other founders the same question: how are you handling dollar invoices? The answers were depressing. Some were using Wise (formerly TransferWise), but Wise is a personal money transfer tool, not built for recurring invoicing. Some were asking clients to pay into Stripe, which meant they needed a US company registration. Others were just accepting the losses and pricing their services higher to compensate.

Tunde came to the problem from a different angle. He was advising a cohort of SaaS founders in Lekki who were all building B2B software targeting African markets. They were getting paid in dollars by customers across Nigeria, Kenya, Ghana, and South Africa. The complexity wasn't just the invoicing—it was the reconciliation, the tax reporting, the FX hedging. "Everyone was doing it differently," Tunde says. "And nobody had a good solution."

They started working together in late 2023, initially as advisors to founders. But by mid-2024, they decided this was big enough to build a company around. The CBN's push toward formalised remittance corridors and the rise of stablecoin-adjacent solutions made the timing feel right. But more importantly: there were now enough dollar-earning SMEs in Nigeria that the unit economics could work.

Building the product: why invoicing alone wasn't enough

Kola's first version was straightforward: a web app where you create an invoice in USD, send it to a client, and get paid. But Ada and Tunde quickly realised that invoicing was just the entry point. The real problem was the settlement layer.

"If we just built another invoicing tool, we'd be competing with Wave and Zoho," Ada explains. "But we're not in Lagos or San Francisco. We're serving people in Kano, Ibadan, and Accra. The payment rails are different. The FX volatility is different. The tax reporting is different. So we had to build the whole stack."

They spent the first three months of product development talking to their users again. Not in a Zoom call—in person. Ada took trips to Kano to meet with cotton exporters. Tunde spent time with e-commerce founders in Accra. They watched how people actually used invoicing tools, what data they needed to extract, and what happened after payment landed.

The key insight: most SMEs don't want the money to hit a virtual account and sit there. They want it converted to naira and in their bank account within hours. They want to see the exact FX rate they got. They want a record for tax purposes. And they want to know, in real time, how much of their invoice actually made it to their pocket.

That's why Kola's product is built in three layers:

1. Invoicing: Create and send invoices in USD, EUR, or GBP. Customise branding. Add line items, taxes, payment terms.
2. Payment collection: Clients pay into a Kola virtual account (which Kola provisions through partnerships with Moniepoint and other licensed fintech operators). Payment settles instantly to Kola's clearing account.
3. Settlement: Kola converts to naira using live FX rates (they've built integrations with Paystack and Flutterwave's rate APIs) and moves the cash to your local bank account within 2-4 hours. You get a full breakdown: invoice amount, FX rate applied, Kola's fee (which is 1.2%, flat), and net naira amount.

This three-layer approach is why Kola isn't just a payment processor. It's a full invoicing and settlement system built for African SMEs. And it's why the comparison to Paystack or Flutterwave doesn't quite work—those are payment processors; Kola is invoicing infrastructure. If you're curious how those platforms stack up against each other in 2026, there's a full comparison available, but Kola sits in a different layer of the stack.

The technical challenges: virtual accounts and FX

The hardest part wasn't the invoicing. It was the virtual account infrastructure.

In Nigeria, if you want to issue a virtual account number to a customer, you need to be licensed by the CBN, or you need to partner with someone who is. Kola chose the partnership route. They integrated with Moniepoint (which holds an IMF license) and built connectors to other licensed fintech operators. When you create an invoice in Kola, the system provisions a unique virtual account in real time. When a client pays, Kola's webhook catches the notification, validates it, and marks the invoice as paid.

The second challenge was FX. Nigeria's naira is volatile. The official CBN rate, the parallel market rate, and the Paystack/Flutterwave rates are often 5-10% apart. Which rate should Kola use?

"We started with Paystack's rate," Tunde explains. "But we realised that founders wanted choice. Some of them hedge FX through their own banks. Some of them want to lock in a rate for the day. Some of them want real-time rates."

Kola now lets you set your preferred rate source: CBN official, Paystack, Flutterwave, or a custom rate you input. You can also set a daily lock-in—so if the naira moves 2% overnight, you're not caught out. This granularity is what separates Kola from a basic payment processor. If you're building a startup that earns in dollars, understanding your FX strategy is critical—there's a detailed guide on FX strategy for Nigerian startups that covers this in depth.

Pricing and the unit economics

Kola charges 1.2% per transaction. That covers the virtual account provisioning (which costs them ~0.3%), the FX conversion (0.2%), the bank settlement (0.3%), and their operating margin (0.4%).

Compare that to the traditional route: Paystack (1.5%) + bank fee (1%) + FX slippage (2-3%) = 4.5-5.5%. Kola is saving SMEs 3-4% per transaction.

For a founder invoicing $50,000 per month, that's $600-$800 per month in recovered margin. Over a year, that's $7,200-$9,600. At scale, that's significant.

Ada and Tunde knew they couldn't compete on price alone. But they could compete on transparency and speed. "We show you exactly what you're paying," Ada says. "No hidden fees. No FX markup. No surprise delays."

They're also not trying to be everything. They're not a bank. They're not a payment processor. They're invoicing infrastructure for SMEs earning in hard currency. That focus is what lets them keep fees low and product quality high.

Go-to-market: how they found their first 100 users

Kola launched in private beta in August 2024 with 12 users. All of them were referrals from Ada and Tunde's networks—founders they knew, agency owners they'd advised, exporters they'd met.

The first month was chaos. Bugs in the settlement logic meant two users didn't get paid on time. The virtual account provisioning failed for one user because Moniepoint's API had a rate limit Kola wasn't expecting. Ada spent a weekend on a call with a client in Kano, walking through manual settlement because the automation broke.

But here's what happened: those users didn't leave. They complained, sure. But they saw that Ada and Tunde were actually fixing things. They saw that this was a real product built by people who understood their problem.

By month two, they had 40 users. By month three, 100. No paid ads. No fancy marketing. Just word of mouth and a product that worked.

The playbook was simple:

1. Find the pain: Digital agencies, SaaS founders, exporters—anyone invoicing in hard currency and losing money to friction.
2. Show the math: "You're losing $800 per month. Here's how Kola saves you that."
3. Make onboarding frictionless: You can create your first invoice in under 5 minutes. The first payment is always a test payment—Kola doesn't charge.
4. Obsess over support: When something breaks, Ada or Tunde picks up the phone. Not a support ticket. A call.

They've now hit 500+ users across Nigeria, Ghana, and Kenya. Monthly transaction volume is around $2.5M USD equivalent. They're not profitable yet—they're still in growth mode—but the unit economics work.

What they got wrong (and what they'd do differently)

Ada and Tunde are candid about their mistakes.

First mistake: they built too many features too early. In the first version, they added expense tracking, accounting integrations, and tax reporting. "We thought founders wanted all of that," Tunde says. "But they didn't. They wanted invoicing and settlement. Everything else was noise." They stripped it back. Now they do one thing well: get paid in dollars, settle in naira, fast.

Second mistake: they underestimated the compliance burden. Nigeria's CBN has strict rules about money movement and settlement. Kola had to get multiple compliance reviews before they could launch publicly. "We budgeted two months," Ada says. "It took six." They now have a dedicated compliance person and a relationship with a law firm that specialises in fintech regulation.

Third mistake: they didn't charge early. The first 100 users were free. "We should have charged from day one," Tunde says. "Not to make money—to validate that users actually valued the product. Free users are noisy. Paying users are committed."

If they were starting over, they'd charge from beta. They'd focus on one user segment (probably digital agencies first, since they're easier to sell to). And they'd spend more time on compliance before building product.

Why now? Why this works in 2026

There are three reasons Kola works now and wouldn't have worked five years ago.

First: there are enough dollar-earning SMEs. In 2020, maybe 5,000 Nigerian SMEs were earning meaningful dollar revenue. In 2026, it's probably 50,000+. Remote work, SaaS, e-commerce, and digital services have all scaled. The market is big enough to support a company.

Second: the fintech infrastructure is mature enough. Moniepoint, Paystack, Flutterwave, and others have built APIs and partnerships that let companies like Kola plug in. Five years ago, you'd have to build everything yourself. Now you can focus on the user experience.

Third: founders are tired of losing money to friction. The naira's weakness (it's moved from ~400 to ~1,600+ per dollar since 2020) has made FX costs visible. Founders are actively looking for solutions. Kola arrived at the right moment.

The future: what's next for Kola

Ada and Tunde are now thinking about expansion. They're exploring multi-currency wallets (so you can hold USD, EUR, and GBP in one account). They're building integrations with accounting software (Zoho Books, Wave, Xero). They're looking at East Africa—Kenya and Uganda have similar problems.

But they're being disciplined about scope. "We're not trying to be Stripe," Ada says. "We're trying to be the invoicing and settlement layer for African SMEs earning in hard currency. That's a specific problem, and we're going to solve it better than anyone else."

They're also thinking about profitability. Right now, they're burning cash to grow. But the unit economics are good enough that they think they can hit breakeven by Q4 2026 if they keep growing at current rates.

FAQ

Q: How is Kola different from Paystack or Flutterwave? A: Paystack and Flutterwave are payment processors—they help you collect payments from customers. Kola is invoicing infrastructure for cross-border payments. You create an invoice, clients pay into a virtual account, and Kola settles to your naira account. It's a different layer of the stack, optimised for SMEs earning in hard currency.

Q: What happens if the naira crashes while I'm waiting for settlement? A: You can set a daily FX lock-in, which freezes the rate for 24 hours. Or you can choose to use the real-time rate at settlement time. Kola shows you all the options and lets you decide.

Q: Can I use Kola if I'm outside Nigeria? A: Kola currently serves Nigeria, Ghana, and Kenya. If you're in one of those countries and have a local bank account, you can use Kola to invoice clients globally and settle locally.

Q: What's the minimum transaction size? A: There's no minimum. You can invoice for $100 or $100,000. Kola charges 1.2% either way.

Q: How long does settlement actually take? A: Once a client pays into your virtual account, Kola converts to naira and settles to your bank within 2-4 hours. In practice, most settlements happen within 2 hours during business hours.

What to do next

If you're a Nigerian SME earning in dollars, go try Kola. Create an invoice, send it to a test client, and see what the settlement actually looks like. The first invoice is free.
