In every organization, finance is the heart of operations. Yet common problems persist: delayed journal entries after receiving payments, late receipt issuance, outstanding debts not cleared after payment, bank data discrepancies, and withholding tax complications. This article explains how the Finance Module in ERP handles all of these — from receiving and making payments to direct bank system integration.
What Is a Finance System?
The Finance Module, or Finance Module (FI), manages all incoming and outgoing payments for the organization, fully integrated with other ERP modules:
- Accounts Payable (AP) — Outstanding payables are sent to FI for payment processing
- Accounts Receivable (AR) — Receivables are sent to FI for receipt issuance
- Budget (BG) — Verifies available budget before approving disbursements
- General Ledger (GL) — All receipts and payments are automatically posted to the ledger
Core Functions of the Finance System
| Code | Function | Description |
|---|---|---|
| FI-01 | Deposit Slip | Records bank deposits with receipt references |
| FI-02 | Receipt | Issues receipts upon payment, linked to invoices |
| FI-03 | Payment Request | Prepares disbursement requests referencing AP payables |
| FI-04 | KTB Corporate Online Integration | Sends payment data directly to KTB's banking system |
| FI-05 | Withholding Tax | Automatically calculates and records withholding tax (PND 53) |
Revenue Collection
Revenue collection in ERP starts from invoices (AR) and flows into the finance system step by step:
FI-02 Receipt
When a customer or agency makes a payment, the system automatically links to the invoice (AR) with no duplicate data entry:
- Invoice data is pulled in instantly to generate receipts
- Receivable balances are automatically cleared when receipts are issued
- Supports partial payments
FI-01 Deposit Slip
After receiving payment, the system records the bank deposit:
- References the related receipt
- Records the bank account for the deposit
- Summarizes daily deposit totals
The system handles multiple revenue types including budget allocations, subsidies, and operating income — all flowing through a single system with accurate ledger postings.
Payment Processing
The payment side involves multiple approval and verification layers, all managed by the system:
FI-03 Payment Request
- References payables from AP directly — no duplicate data entry
- Verifies budget availability before approval
- Routes through the defined approval hierarchy
CP-01 Check Issuance
- Print checks directly from the system
- Records check number, check date, and encashment status
FI-04 KTB Corporate Online
- Make payments directly through KTB's banking system (no checks needed)
- Automatically send payment files from ERP to KTB
FI-05 Withholding Tax (PND 53)
- The system automatically calculates withholding tax based on expense type
- Generate withholding tax certificates directly from the system
KTB Corporate Online Integration
One of the most time-saving features is the integration between ERP and KTB Corporate Online from Krungthai Bank, which automates nearly the entire payment process:
Benefits of KTB Corporate Online Integration
- Send payment files directly from ERP to KTB — no duplicate data entry in the banking system
- No check printing needed — reduces costs for checks, stamp duties, and handling time
- Payment results automatically update back to ERP — no manual status checking needed
- Reduces risk of lost or forged checks — funds transfer directly to the recipient's account
For organizations with high volumes of monthly payments, KTB Corporate Online integration significantly reduces processing time — no individual check printing, no check signing, no check delivery, and no tracking of un-encashed checks.
Withholding Tax (FI-05)
Withholding tax is required with every payment, but issues often arise because tax rates vary by expense type, calculations are error-prone, and month-end data consolidation is difficult. The FI module handles it all:
- Automatic tax rate calculation — Tax rates are configured by expense type, and the system calculates automatically when processing payments.
- Generate PND 53 from the system — Print withholding tax certificates instantly.
- Monthly tax summaries — Consolidate data for Revenue Department submission without gathering from multiple sources.
Workflow
The finance system operates in sequential, interconnected steps for both revenue collection and payments:
Revenue Collection Flow
Invoice (AR) → Receive Payment → Receipt (FI-02) → Bank Deposit (FI-01) → Post to Ledger (GL)
Payment Flow
Payable (AP) → Payment Request (FI-03) → Approval → Pay via KTB/Check (FI-04/CP-01) → Withholding Tax (FI-05) → Post to Ledger (GL)
Every step is automatically connected — data flows from one module to the next without re-entry, reducing errors, saving time, and enabling full traceability for every transaction.
Good finance management isn't just about making correct payments — it's about having connected data from budget through procurement to payment. Every baht has a traceable origin and can be audited at every step.
