SaaS is a business model before it is an architecture
Building software that many customers share is a different discipline from building one system for one organisation. The technical differences — tenant isolation, per-customer configuration, metered usage — all follow from a commercial model where customers self-serve, pay monthly, and leave if the product stops earning its fee.
That has consequences for what you build first. A SaaS product needs signup, billing, and a working core feature before it needs breadth. Products that launch with twenty features and no billing integration cannot learn whether anyone will pay.
We scope first releases around the shortest path to a paying customer, then expand based on what those customers actually use.
What a SaaS build includes
- Multi-tenant data architecture with enforced isolation between customers
- Self-service signup, onboarding and account provisioning
- Subscription billing — Telebirr and Chapa for the Ethiopian market, Stripe or Paddle for international
- Usage metering and plan limits
- Role-based access control within each customer organisation
- Admin tooling so your team can support customers without database access
- Usage analytics that show which features earn their keep
- Automated backup, monitoring and incident alerting
Tenant isolation: the decision that is expensive to reverse
Most early-stage products should start with a shared schema and rigorous access controls. It is the cheapest to operate and the fastest to change while the product is still moving.
Move to stronger isolation when a specific customer or regulatory requirement demands it — not preemptively. Retro-fitting is work, but building database-per-tenant for three customers is work you may never need.
| Model | How it works | Trade-off |
|---|---|---|
| Shared schema | All tenants in the same tables, separated by a tenant ID | Cheapest to run and easiest to update; isolation depends entirely on correct application code |
| Schema per tenant | Each tenant gets its own schema in a shared database | Stronger separation, more predictable per-tenant work; migrations get harder as tenants grow |
| Database per tenant | Each tenant fully separate | Strongest isolation and easiest per-customer export; highest running cost and operational overhead |
Billing for Ethiopian and international customers
Products selling domestically need local payment rails. Telebirr and Chapa are the practical options for recurring ETB collection, and each has its own handling of recurring authorisation that shapes how you model subscriptions.
Products selling internationally need card processing in USD, which introduces merchant account and settlement considerations that are worth resolving before you write billing code rather than after.
Many Ethiopian SaaS products end up doing both, on different plans. That is workable, but the billing model has to be designed for it from the start — bolting a second currency and provider onto a single-currency subscription system is one of the more painful retrofits we see.
Build order that reduces risk
1. One core workflow
The single thing a customer would pay for, working end to end for one tenant.
2. Multi-tenancy
Isolation, provisioning and per-tenant configuration once the core is proven.
3. Billing
Signup, plans, payment and failed-payment handling. Until this exists you have no business.
4. Self-service onboarding
Removing your team from the signup path is what makes the model scale.
5. Admin and analytics
Support tooling and usage data, so you can help customers and see what they use.
Operating cost planning
SaaS economics depend on cost per tenant staying well below revenue per tenant, and infrastructure cost is only part of it. Support time, payment processing fees and the ongoing engineering required to keep the platform current all scale with customer count.
We model this with you before build, because it determines architecture. A product priced at a low monthly fee cannot afford a database per customer; a product with a small number of high-value enterprise customers can.
Cloud costs are billed in USD, which for Ethiopian operators makes forex availability an operational concern rather than a purely financial one. We factor it into the hosting design rather than treating it as someone else's problem.
Frequently Asked Questions
How long until we can charge our first customer?
For a focused product with one core workflow and billing, a few months is realistic. Products attempting broad functionality before launch take considerably longer and learn less, which is why we push hard toward a narrow first release.
Should we build for the Ethiopian market or internationally?
It is a strategic choice with real technical consequences — payment rails, currency, language and support hours all differ. Deciding early is more important than which you pick, because retrofitting the other is expensive.
Can you take over an existing SaaS product?
Yes. We start with an assessment of the codebase, architecture and operational setup, then give you an honest view of whether it should be extended or progressively replaced. We will tell you if the answer is uncomfortable.
Do we own the intellectual property?
Yes. On final payment you own the code, the repositories and the deployment configuration, with documentation to run it independently.
What ongoing work does a SaaS product need?
More than most people budget for. Dependency and security updates, payment provider API changes, customer support tooling and infrastructure maintenance all continue regardless of new features. Plan for a continuing engineering commitment, not a one-off build.
