Do I need to register a company to run a payment integration agency?

For small client work, you can start as a sole trader. To take larger contracts (KES 200,000+ or NGN 2M+), clients typically want to pay a registered entity. Register a business name with your county business registry (Kenya) or CAC (Nigeria). For clients requiring invoices with PIN/TIN, you need a registered business and KRA PIN or FIRS TIN.

How many clients can one developer handle?

One developer can manage 3-5 active integration projects simultaneously and 8-15 maintenance retainer clients. Beyond that, you need to hire. Start with contract developers on a per-project basis before committing to full-time hires. Tools like GitHub, Linear, and Notion help you manage multiple client projects.

What makes payment integration clients stick vs. churn?

Clients stay when you solve problems before they notice them. Set up monitoring (webhook failure alerts, settlement delay notifications) and proactively contact clients when you catch an issue. Clients who feel their integration is being watched over do not shop around. Clients who only hear from you when something breaks will eventually replace you.

Building a Payment Integration Agency

Start by completing 2-3 paid integrations as a freelancer to build your portfolio. Define your service packages: Basic Checkout (fixed price), Marketplace Integration, Subscription Billing, and a Monthly Maintenance retainer. Charge in KES or NGN based on your target market. Get your first clients from your existing network, LinkedIn, and Twitter/X posts showing your work. Grow by hiring junior developers on a project basis, then full-time as volume justifies.

Service Packages to Offer

Package	What It Includes	Typical Price (KES)
Basic Checkout	Paystack Popup, webhook handler, email receipt, 1 country	20,000 – 50,000
Full Stack Checkout	Custom checkout UI, M-Pesa + card, multiple countries, test suite	60,000 – 150,000
Marketplace	Split payments, subaccounts, vendor payout system, dashboard	120,000 – 350,000
Subscription Billing	Plans, billing cycles, dunning, pause/cancel flows	80,000 – 200,000
Monthly Maintenance	Monitoring, updates, support, webhook health checks	8,000 – 30,000/month

Convert 30% of one-off projects to maintenance retainers — this is your most stable revenue stream. When handing over a completed project, include a maintenance offer in your final invoice.

Getting Your First Clients

Your network — list 20 people you know who run businesses. Which ones take payments online? Ask if they are happy with their current checkout or need help.
LinkedIn — post about Paystack integrations, M-Pesa troubleshooting, and checkout optimization. Decision-makers at SMEs follow this content.
Twitter/X — share integration tips tagged #Paystack, #Daraja, #AfricanFintech. Paystack and M-Pesa support accounts sometimes retweet helpful content.
Referrals — your best growth channel. Every satisfied client is a referral source. Send a thank-you and ask "do you know anyone else who needs this?"
Upwork/Fiverr — create profiles with "Paystack integration Kenya" or "M-Pesa Daraja developer Nigeria." Inbound leads from diaspora-backed African startups come here.
