The verdict in three sentences
A foreign accounting SaaS costs USD 20-60 per user per month in Nairobi in 2026, while a custom solution tuned to local standards runs USD 20,000-50,000. SaaS is quick to start but bills in foreign currency, adapts poorly to local chart-of-accounts and tax rules, and hosts your client data off the continent. For a firm heading toward 10-plus staff, custom solves currency risk, local tax compliance and data sovereignty at once.
Foreign SaaS vs local custom: the real criteria
The sticker price does not tell the whole story. Here is the structuring comparison for a Nairobi firm (2026 estimate).
| Criterion | Foreign SaaS | Local custom |
|---|---|---|
| Entry cost | USD 20-60/user/month | USD 20,000-50,000 |
| Billing | In USD/EUR (FX risk) | In local currency, fixed |
| Local chart of accounts | Partial / workarounds | Native |
| Client payments | Card only | M-Pesa, mobile money, card |
| Data hosting | Off Africa | Configurable, local possible |
| Support | Foreign time zone/language | Local, in English |
| Setup time | 1-4 weeks | 4-6 months |
5-year TCO and currency risk
With a SaaS at USD 40/user/month, here is the cumulative 5-year cost versus a custom build at USD 34,000 (plus support of USD 450/month).
| Team members | SaaS 5 yrs (USD) | Custom 5 yrs (USD) | Verdict |
|---|---|---|---|
| 5 | 120,000 | 61,000 | Custom |
| 8 | 192,000 | 61,000 | Custom |
| 12 | 288,000 | 61,000 | Custom |
| 20 | 480,000 | 61,000 | Custom |
At constant FX, custom becomes cheaper from just 3-4 staff over 5 years. And the table ignores currency risk: a 10 % rise in the dollar mechanically inflates the entire SaaS bill, with no added value in return. Custom, billed and maintained in local currency, shields you from that volatility.

Mini case study
Mr. Otieno, partner at a 12-person accounting firm in Nairobi, uses a foreign SaaS at USD 40/user/month, i.e. USD 480/month. Over 5 years that is more than USD 288,000, in foreign currency. A custom solution at USD 34,000, tuned to local standards with mobile-money collection built in, costs USD 61,000 over 5 years including support. The saving exceeds USD 227,000, while keeping client data hosted locally and billing in local currency.
FAQ
Does custom really handle local tax rules? Yes, natively: chart of accounts, statutory statements and returns are modelled from the start, with no workarounds or double entry.
How much is the starter version? A core of accounting + billing + client portal starts around USD 20,000 for roughly four months of development.
Can we collect via mobile money? Yes; mobile-money integration is standard, with confirmation webhooks and automatic payment reconciliation.
What is the annual maintenance budget? Expect USD 350 to 850/month depending on module count and the tax changes to be tracked.
Where is the data hosted? Your choice: local or regional hosting is possible, guaranteeing client data sovereignty, unlike most foreign SaaS.
