Launching a Software-as-a-Service (SaaS) business in Nigeria is a massive opportunity as local SMEs digitize. However, SaaS requires specific architectural decisions around multi-tenancy, security, and subscription billing.
Multi-Tenancy: Shared Database vs Isolated Databases
For most startups, a Shared Database (Logical Separation) using a tenant_id column on every table is the most cost-effective and scalable approach. Use Postgres Row Level Security (RLS) to ensure no tenant can ever see another's data.
Subscription Billing in Naira & USD
In Nigeria, recurring cards can fail due to bank restrictions or OTP challenges. Offer both Card Auto-Renewal via Paystack Subscriptions and automated Virtual Bank Transfers for monthly top-ups.
Nigerian B2B buyers often prefer annual bank transfers over monthly credit card subscriptions. Ensure your billing engine supports manual bank reconciliation with automated account credits.
Security & Compliance (NDPR)
Under the Nigeria Data Protection Regulation (NDPR), you must encrypt all user data in transit and at rest. Use HTTPS, secure JWTs, and host your databases in regions that comply with local guidelines.
