FOSA vs BOSA: How the Two Sides of a SACCO Work
7 April 2026
Understand the difference between FOSA and BOSA accounts, deposits, loans and services in a Kenyan SACCO.

FOSA and BOSA are common SACCO terms, but they describe different parts of the member relationship. BOSA is the traditional savings and credit side. FOSA provides front-office transactional services in a licensed deposit-taking SACCO.
What happens in BOSA
BOSA commonly handles member deposits, share capital, guarantor-based loans and payroll deductions. Deposits may support the loan multiplier and are often non-withdrawable until the member exits or meets the SACCO’s conditions.
What happens in FOSA
FOSA may provide withdrawable savings, salary processing, standing orders, mobile access, ATM services and short-term advances. The exact products differ between SACCOs. A FOSA account behaves more like a transactional account, but the institution remains a SACCO rather than a commercial bank.
A simple example
Otieno’s employer sends KES 60,000 to his FOSA salary account. The SACCO automatically transfers KES 5,000 to BOSA deposits and KES 12,000 to repay his development loan. He uses the remaining FOSA balance for ordinary payments. The two sides are connected, but the balances have different rules.
Do all SACCOs have FOSA?
No. FOSA services require the appropriate deposit-taking licence. An NWDT-SACCO can still offer loans and receive non-withdrawable deposits without operating a full front-office deposit business.
What to compare
Check FOSA charges, withdrawal access, digital channels, salary processing and short-term loan pricing. For BOSA, check contribution requirements, multiplier, guarantor rules, long-term loan rates and exit conditions.
Bottom line
FOSA is for day-to-day access. BOSA is the long-term savings, ownership and credit relationship. Read both fee schedules before moving your salary.
Editorial note: Product names and account rules differ between SACCOs.
