Connected by Design

One system from daily operations to accounting

MESOS connects the business document, inventory movement, payment, accounting effect, tax treatment and related adjustment instead of treating every module as a separate process.

Built around the transaction lifecycle

Start with the operational document your team actually uses. MESOS keeps the next document, stock movement, payment and accounting treatment connected as the transaction progresses through the business.

Operations Sales, purchasing, inventory, POS and F&B POS in one working environment.

Accounting Business transactions flow into the double-entry accounting framework.

Malaysia-ready Tax and LHDN MyInvois information remain connected to the underlying transaction.

Sales

Manage the complete sales process

Keep customer-facing sales documents connected from the first proposal through fulfilment, invoicing, payment and subsequent adjustments.

Proposal / Quotation

Prepare customer proposals and quotations before moving an accepted transaction into the sales process.

Sales Order

Record confirmed customer orders and keep the order connected to the documents that follow.

Delivery Order

Record goods delivered to customers and maintain the relationship back to the originating sale.

Sales Invoice

Issue customer invoices with product, tax, currency, payment and accounting information connected to the transaction.

Credit Note & Debit Note

Adjust the original sales transaction while preserving the relationship between the adjustment and its source document.

Customer Payments

Record customer settlements against sales documents and keep paid and outstanding amounts connected to receivables.

Purchasing & Expenses

Handle stock purchases and non-stock vendor bills correctly

MESOS separates inventory procurement from ordinary operating expenses, so stock-related purchases and non-stock vendor bills follow the right workflow.

Purchase Order

Create and manage purchase orders for products and stock being procured from suppliers.

Goods Received Note

Record goods received from suppliers and keep the receiving process connected to purchasing activity.

Purchase / Supplier Bill

Record stock-related supplier purchases, costs and liabilities while keeping the purchase connected to inventory and accounting.

Bill (Other Vendor)

Record bills and operating expenses that are not related to inventory, such as rental, utilities, professional fees, maintenance, subscriptions and other vendor charges. MESOS records the expense, payable and subsequent payment through the accounting workflow without creating stock movements.

Non-stock related expenses

Purchase Credit & Debit Notes

Adjust supplier purchase transactions while preserving the relationship with the original purchase document.

Supplier Payments

Record payments made to suppliers and maintain the remaining payable balance against the relevant purchase transaction.

Other Vendor Bill Payments

Settle non-stock vendor bills through the payable workflow without creating any inventory movement.

Inventory

Keep products and stock movements connected

Inventory activity follows the underlying purchase, sale and applicable adjustment instead of being maintained as a separate record.

Products & Services

Maintain products and services in one catalogue for use across sales, purchasing, POS, tax and accounting workflows.

Stock Tracking

Track stock movement generated by applicable purchasing, sales and inventory-related transactions.

Adjustment Stock Effect

Where an adjustment affects inventory, MESOS can preserve the appropriate stock effect instead of treating every credit or debit adjustment the same way.

Purchasing-to-Stock Flow

Goods received and stock-related purchases remain connected to the inventory movement that they create.

POS Inventory Integration

Applicable POS sales feed back into inventory so operational sales and stock movement remain connected.

POS & F&B POS

Front-counter sales connected to the back office

Process day-to-day counter and food-and-beverage transactions while keeping customer, inventory and accounting information within the MESOS environment.

Point of Sale

Process ordinary counter sales through MESOS POS with the transaction linked back to the business system.

F&B POS

Use a dedicated food-and-beverage POS workflow for operational sales while retaining back-office integration.

Walk-in & Registered Customers

Handle normal walk-in sales while retaining customer records for transactions that need an identified customer.

POS-to-Inventory

Applicable POS sales can update stock movement so sales activity and inventory do not operate as separate records.

Accounting Integration

POS transactions feed the MESOS accounting framework instead of operating as disconnected front-counter sales records.

Accounting

Accounting connected to real business transactions

MESOS links operational transactions to the accounting framework so the ledger reflects what actually happened in sales, purchasing, payments and adjustments.

Double-Entry Accounting

Business transactions post through the MESOS double-entry accounting framework with debit and credit effects kept in balance.

General Ledger

Keep accounting entries linked to the operational transactions that generated them for clearer financial records.

Accounts Receivable

Track customer invoices, payments, adjustments and remaining receivable balances within the sales lifecycle.

Accounts Payable

Track supplier purchases, other vendor bills, payments, adjustments and outstanding payable balances.

Central Posting Rules

Accounting treatment is controlled through central posting logic rather than each business module independently deciding its own entries.

Adjustment Relationships

Credit, debit and reversal-related accounting effects can retain their relationship to the transaction being adjusted.

Malaysia Tax

Tax treatment connected across the transaction

Configure Malaysia tax information centrally and carry the applicable treatment through products, sales, purchasing and related adjustment documents.

Central Tax Configuration

Keep tax setup in one central configuration instead of maintaining independent tax rules in every document workflow.

Malaysia SST

Maintain the relevant Malaysia Sales and Service Tax configuration used by applicable business transactions.

Product Tax Classification

Keep tax classification information with products and services so it can be applied consistently in transaction workflows.

Inclusive & Exclusive Pricing

Support transactions where tax is included in the displayed price or added separately according to the configured pricing treatment.

Sales & Purchase Tax Treatment

Carry the applicable tax information into sales and purchasing transactions instead of treating tax as a disconnected field.

Credit / Debit Note Tax Continuity

Keep adjustment tax treatment tied to the underlying transaction instead of independently selecting an unrelated tax treatment.

LHDN MyInvois

Malaysia E-Invoice built into the MESOS workflow

Keep E-Invoice submission and MyInvois information connected to the same business transaction and accounting record already managed in MESOS.

MyInvois Integration

Prepare and submit eligible Malaysia E-Invoice transactions to LHDN MyInvois through the MESOS workflow.

Validation Status

Keep the MyInvois submission result visible so validated or rejected documents can be identified inside MESOS.

Customer E-Invoice Information

Maintain the customer identification and tax information needed for applicable E-Invoice transactions.

Product & Service Classification

Use product and service classification information as part of the MyInvois transaction preparation process.

Consolidated POS E-Invoice

Support consolidated MyInvois processing for applicable POS transactions through the MESOS E-Invoice workflow.

E-Invoice Credit & Debit Notes

Keep E-Invoice-related sales adjustments linked to the underlying transaction instead of creating a disconnected adjustment record.

Validated E-Invoice Details

Keep submitted document details and the information used to access the validated MyInvois E-Invoice available within MESOS.

Multi-Currency

Work with transaction and base currencies

Keep foreign-currency transaction values and their corresponding base-currency amounts connected throughout the document and accounting workflow.

Foreign-Currency Transactions

Use a transaction currency on applicable sales and purchase documents while retaining the company base currency.

Exchange Rates

Apply an exchange rate to convert the transaction amount into the relevant base-currency accounting value.

Base-Currency Visibility

Show the corresponding base-currency amount alongside foreign-currency values where exchange-rate conversion applies.

Accounting Currency Treatment

Keep foreign-currency transaction values connected to the base-currency amounts used by the accounting entries.

Customers & Suppliers

Keep counterparties connected to their transactions

Customer and supplier records remain connected to sales, purchasing, balances, payments, tax and E-Invoice information.

Customer Records

Maintain customer details for use across proposals, sales, invoices, payments, tax and E-Invoice transactions.

Supplier & Vendor Records

Maintain supplier and other vendor information for stock purchases, operating expenses, payables and settlements.

Payments & Adjustments

Keep settlements and related adjustment documents associated with the underlying customer or vendor transaction.

Tax & E-Invoice Information

Store the relevant tax and identification information required when a customer or supplier transaction needs it.

Document Workflow

Documents that follow the business process

Move through the sales and purchasing lifecycle with related documents instead of repeatedly recreating disconnected information.

Sales Flow

From the first customer offer through fulfilment and settlement.

Proposal → Sales Order → Delivery Order → Invoice → Payment / Adjustment

Purchasing Flow

From stock procurement through receiving, liability and settlement.

Purchase Order → GRN → Purchase → Payment / Adjustment

Non-Stock Expense Flow

Operating expenses can bypass inventory entirely while still following accounts payable.

Other Vendor → Bill → Expense / Payable → Payment

Adjustment Continuity

Credit Notes and Debit Notes remain connected to the underlying transaction they are intended to adjust.

Original Document → Credit / Debit Note → Accounting / Tax Effect

Users & Controls

Control access around business responsibilities

Give users access to the MESOS functions required for their role while keeping accounting and transaction responsibilities controlled.

Multiple Users

Support different users working across the operational and accounting areas of the same MESOS environment.

Role-Based Access

Assign access according to the user's business responsibilities rather than exposing every function to every user.

Module Permissions

Control which functional areas a user can access within the wider MESOS business workflow.

Controlled Accounting Roles

Keep accounting responsibilities within designated roles instead of making sensitive accounting operations universally available.

Transaction Lifecycle Controls

Keep operational actions tied to the appropriate transaction state and document relationships.

Integrated Business Management

One transaction. One connected business system.

MESOS connects sales, purchasing, non-stock expenses, inventory, POS, accounting, tax and Malaysia E-Invoice within the same transaction lifecycle. The operational document, stock effect, payable or receivable, accounting entry, tax treatment and related adjustment can remain connected instead of becoming separate records in separate systems.
