Payment Schedules User Guide

Overview

The Payment Schedules feature in Nama ERP allows you to define flexible payment terms and installment plans for sales documents. This comprehensive guide covers the setup and usage of payment schedule templates and their application to sales transactions.

Understanding Payment Schedules

Payment schedules allow businesses to:

• Define installment payment plans for customers
• Set up down payments and deferred payment terms
• Automatically calculate payment dates and amounts
• Track payment collections against scheduled payments
• Manage both fixed-value and percentage-based payment plans

Key Components

1. Payment Schedule Template (نموذج جدولة الدفعات): Master file defining reusable payment terms
2. Schedule Lines: Individual payment installments with dates and amounts
3. Payment Tracking: System tracking of actual payments against scheduled amounts

Payment Types and Methods

Equal Payments Method

The system automatically divides the remaining amount into equal installments:

Calculation Formula:

Payment Amount = (Total - Down Payment) / Number of Payments
Last Payment = Adjusted for rounding differences

Example:

• Invoice Total: 120,000
• Down Payment: 20,000 (or 16.67%)
• Remaining: 100,000
• Payments: 10
• Each Payment: 10,000

Variable Payments Method

Define custom payment amounts or percentages for each installment:

Percentage-Based:

Payment Amount = Total × Payment Percentage

Fixed Value:

Payment Amount = Specified Fixed Value

Mixed Example:

Applying Templates to Sales Documents

Payment Schedule Templates can be applied to:

• Sales Quotations
• Sales Orders
• Sales Invoices
• Any document implementing the HasPaymentSchedule interface

Application Process

1. Open Sales Document
2. Select Payment Template in the Payment Schedule section
3. System Calculates schedule based on:
   • Document total amount
   • Template configuration
   • Update type settings
4. Review Generated Schedule in the Schedule Lines grid
5. Manual Adjustments (if template allows)
6. Save Document to finalize schedule

Generated Schedule Information

For each scheduled payment:

• Payment Date: Calculated based on template periods
• Payment Value: Calculated amount
• Payment Percent: Percentage of total
• Remaining: Outstanding amount after payments
• Installment Code: Unique identifier for tracking

Payment Schedule Calculations

Date Calculations

First Payment Date:

Document Date + Grace Period = First Payment Date

Subsequent Payments:

Previous Payment Date + Payment Period = Next Payment Date

Amount Calculations

With Down Payment:

Remaining Amount = Total - Down Payment - External Payments
Payment Amount = Remaining Amount × Payment Configuration

Rounding and Approximation:

Rounded Payment = Round(Payment Amount, Approximation, Rounding Type)
Last Payment = Remaining Amount - Sum of Previous Payments

Validation Rules

The system validates:

1. Total Percentage: Must equal 100% for percentage-based templates
2. Down Payment: Cannot specify both value and percentage
3. Payment Values: Must not exceed remaining amount
4. Payment Dates: Must be valid future dates
5. Template Lines: At least one payment line required for variable payments

Payment Documents and Installment Tracking

Once payment schedules are created and applied to sales documents, the system provides comprehensive tracking through payment documents that can mark installments as paid.

Receipt Vouchers and Payment Vouchers

Both Receipt Vouchers (سندات القبض) and Payment Vouchers (سندات الدفع) include an Installment Lines (الأقساط) collection that enables payment tracking against scheduled installments:

• Receipt Vouchers: Used primarily for sales documents to record customer payments
• Payment Vouchers: Used primarily for purchase documents to record supplier payments

Installment Lines Collection

The installment lines grid in payment documents contains the following key fields:

Payment Processing Logic

When payment documents are committed, the system uses InstallmentUtils to:

1. Update System Paid Fields: Automatically updates the systemPaid amount for each installment
2. Calculate Remaining Balances: Recalculates remaining amounts across all related installments
3. Validate Payment Order: Ensures payments follow proper sequence (earlier installments paid first)
4. Prevent Overpayments: Validates that paid amounts don't exceed installment values

Payment Tracking Process

Step 1: Create Payment Document

1. Open Receipt Voucher or Payment Voucher
2. Enter basic payment information (customer/supplier, amount, date)
3. Navigate to the Installment Lines tab

Step 2: Add Installment Payments

1. Click Add Line in the Installment Lines grid
2. Select the Installment Document (sales invoice, quotation, etc.)
3. Choose the specific Installment Code from the document
4. Enter the Paid Value (can be partial or full payment)
5. Repeat for multiple installments if needed

Step 3: Payment Validation

The system automatically validates:

• Payment amounts don't exceed installment balances
• Payment order follows due date sequence (if configured)
• Referenced installments exist in the source document
• Total payments match the document amount

Step 4: Effect Application

Upon saving the payment document:

• Installment balances are updated across the system
• Related sales/purchase documents show updated payment status
• Aging reports reflect the new payment information
• Customer/supplier accounts are updated

Multi-Document Payment Support

Payment documents can process installments from multiple source documents in a single transaction:

Receipt Voucher RV-2024-001
├── Customer: ABC Company
├── Total Amount: 150,000
└── Installment Lines:
    ├── Invoice INV-001, Installment #1: 50,000
    ├── Invoice INV-001, Installment #2: 25,000
    └── Invoice INV-002, Installment #1: 75,000

Payment Order Enforcement

Configuration Options:

• Strict Order: Must pay installments in due date sequence
• Flexible Order: Allow payments in any order
• Document-Level Setting: Override at individual document level

Installment Payment Entry System

Behind the scenes, the system maintains InstallmentPaymentEntry records that track:

• Payment Document: Which receipt/payment voucher made the payment
• Installment Document: Which sales/purchase document contains the installment
• Installment Code: Specific installment being paid
• Effect Type: How the payment affects the installment (SystemPaid, CollectedByFP, etc.)
• Paid Value: Amount applied to the installment

Summary

Payment Schedules provide flexible payment term management in Nama ERP, enabling:

• Standardized payment terms through templates
• Automatic calculation of installment plans
• Integration with financial modules
• Comprehensive payment tracking

By following this guide and best practices, you can effectively implement and manage payment schedules to improve cash flow management and customer payment terms.
