Loan Product Design & Amortization Methods

1. Overview & Business Value#

This comprehensive operational guide details the architecture, business workflows, configuration parameters, and execution steps for Loan Product Design & Amortization Methods within SmartERP.

Configure cooperative credit products, reducing balance vs flat interest formulas, grace periods, and late payment penalties.

2. Prerequisites & Security Access Groups#

• Required Modules: smarterp_sacco_core, smarterp_equb, smarterp_loan_management
• Security Groups:
  • SACCO Loan Officer (Technical ID: smarterp_sacco.group_sacco_officer)
  • SACCO Credit Committee Member (Technical ID: smarterp_sacco.group_sacco_committee)
  • SACCO General Manager (Technical ID: smarterp_sacco.group_sacco_manager)
• Master Data Dependencies: Member KYC profiles, share capital registers, savings product tiers, loan products with reducing-balance schedules, and Equb rotational pool configurations.

3. Step-by-Step Configuration & Execution#

Step 1: Navigating to the Module Interface#

1. Log into your SmartERP instance at https://smarterp.et/odoo.
2. Open the main App Switcher (grid icon in the top-left corner).
3. Select the SACCO & Equb app icon.
4. From the top navigation bar, open SACCO & Equb → Members → KYC Registry / Savings Accounts / Loan Applications / Equb Pools.

Step 2: Creating and Parameterizing Records#

1. Click the New button in the top-left control panel.
2. Complete the mandatory fields in the record form:
   • Member Identification Number (Mandatory): Unique membership number complying with Ethiopian Cooperative Commission rules
   • Full Name & Kebele ID (Mandatory): Verified member identity with physical residence verification
   • Share Capital Subscriptions (Mandatory): Subscribed shares not exceeding statutory 10% member ceiling (Proclamation 985/2016)
   • Primary Savings Product (Mandatory): Compulsory regular monthly savings account configuration
3. Configure optional operational parameters and localized tags as required:
   • Guarantor & Collateral (Optional): Approved co-signers with locked savings accounts or registered vehicle/property lien
   • Equb Rotational Group (Optional): Linked digital Equb pool with lottery draw eligibility
   • Beneficiary Nominee (Optional): Designated next of kin for death or disability benefit transfer
4. Click the Save icon in the control bar to commit the record.

Step 3: Validating and Processing Transactions#

• State Transitions: Execute operational state progression (Application → KYC Verified → Approved → Active / Disbursed → Delinquency Monitored → Settled).
• Ledger & System Impact: Loan disbursement debits loans receivable and credits cash/bank; loan repayments credit interest income and loan principal, updating 5-tier NBE provisioning registers.
• Audit Verification: Automated recording of author ID, timestamp, and immutable revision history.

Loan Product Diversity in Financial Cooperatives#

SACCOs design targeted credit facilities serving member socioeconomic needs:

• Emergency Micro-Loans: Short-term loans (1 to 3 months) for medical or family emergencies, disbursed within 2 hours.
• Consumer / Asset Financing: Medium-term loans (12 to 24 months) for household appliances, solar systems, or laptops.
• Business & Working Capital: Loans (12 to 36 months) financing member trading, retail shops, or manufacturing.
• Housing & Construction Loans: Long-term loans (3 to 5 years) for home acquisition or residential construction.

Mathematical Amortization Formulas#

SmartERP supports both standard Ethiopian microfinance interest calculation methods:

1. Reducing Balance (Diminishing) Method#

Interest is computed strictly on the remaining unamortized principal balance at each installment:

$$I_t = P_t \times \left( \frac{r}{12} \right)$$

$$\text{Equal Monthly Installment (EMI)} = P_0 \times \frac{\frac{r}{12} \left( 1 + \frac{r}{12} \right)^n}{\left( 1 + \frac{r}{12} \right)^n - 1}$$

Where $P_0$ is principal, $r$ is annual interest rate, and $n$ is total months. Principal repayment increases each month while interest declines.

2. Flat Interest Method#

Interest is calculated on the original initial principal throughout the entire loan tenure:

$$\text{Total Interest} = P_0 \times r \times \left( \frac{n}{12} \right)$$

$$\text{Monthly Installment} = \frac{P_0 + \text{Total Interest}}{n}$$

Note: While simpler, ECC directives strongly encourage reducing balance formulas to promote ethical financial inclusion.

Penalty Interest & Grace Period Setup#

In the loan product configuration canvas:

• Grace Period (Days / Months): Moratorium on principal repayment during project gestation.
• Penalty Interest Rate: Statutory penalty (typically 2% to 5% per annum) applied strictly to overdue principal amounts following a 5-day grace window.

4. Advanced Configuration Points#

• Automated Actions & Scheduled Tasks (Crons):
  • SACCO: Accrue monthly member savings interest (smarterp_sacco.ir_cron_savings_interest): Runs on the final day of each calendar month to credit interest
  • Loan: Evaluate 5-tier NBE delinquency classification (smarterp_sacco.ir_cron_loan_delinquency): Runs nightly to compute loan loss provisions per NBE directives
  • Equb: Execute scheduled lottery draw (smarterp_sacco.ir_cron_equb_draw): Runs on defined pool cycle dates using provably fair random selection
• Custom Print Templates & Reports:
  • Member Savings Passbook & Transaction Ledger
  • Loan Amortization Schedule (Reducing Balance)
  • NBE 5-Tier Delinquency & Loan Loss Provisioning Statement
  • Annual Patronage Dividend Distribution Schedule
• Multi-Company Rules: Record-level security isolation under Company 1 (Ashewa Technology Solutions S.C.), preventing cross-company ledger leakage across parent and subsidiary legal entities.
