Unit 6.5
How ERP Systems Support Business Processes: The Order-to-Cash Cycle
Learning Objectives 🎯
By the end of this session, you will be able to:
- ✅ Explain how an ERP system supports a cross-functional business process.
- ✅ Describe the steps of the Order-to-Cash (O2C) business process.
- ✅ Identify how different ERP modules (Sales, SCM, Finance) interact during the O2C cycle.
- ✅ Understand the power of integration in reducing errors and providing real-time visibility.
The Challenge: Information Silos
Traditional (Siloed) Approach
- Sales has its own system.
- Warehouse has a separate inventory list.
- Accounting uses different software.
- ❌ Manual data re-entry
- ❌ High chance of errors
- ❌ No real-time visibility
Integrated ERP Approach
- One central database.
- All departments use the same system.
- Data entered once is available to everyone.
- ⚡ Automated workflows
- ⚡ Single source of truth
- ⚡ Real-time visibility

The Order-to-Cash (O2C) Cycle
Definition: The Order-to-Cash (O2C) cycle is the complete set of business processes covering the receipt and processing of a customer order, its fulfillment, and the receipt of payment.
It's the core process of how a company makes money from its sales.
Let's see how an ERP makes this seamless.

The O2C Journey: An Overview 🗺️
- Step 1: Create Sales Order (Sales Dept)
- Step 2: Fulfill Order (Warehouse/Operations)
- Step 3: Ship Order (Logistics/Shipping)
- Step 4: Create Invoice (Accounting)
- Step 5: Receive Payment (Accounting)
In an ERP, each step automatically triggers the next, creating a smooth, integrated flow.

🎉 O2C Complete! One system, five modules, zero manual errors.
Step 1: Create Sales Order (Sales Dept)
A salesperson receives a new order from a customer.
- They access the CRM or Sales module to create the order.
-
⚡ Integration in Action: The ERP instantly...
- Checks customer credit limit (Financial Module).
- Verifies and reserves inventory (SCM Module).
- Once confirmed, the order automatically moves to the next stage.

Inventory Check (SCM):—
Steps 2 & 3: Fulfill & Ship (Operations)
Step 2: Fulfill Order (Warehouse)
- Confirmed order appears as a "pick list" in the SCM module.
- Staff picks and scans items.
- 📊 Inventory levels are updated in real-time across the entire system.
Step 3: Ship Order (Logistics)
- SCM module generates shipping documents (packing slip, etc.).
- System can integrate with carriers (e.g., Aramex, local couriers).
- Shipping the order updates its status and triggers invoicing.

Pick list received from ERP — scan each item to confirm.
✅ Pick Complete! ERP has updated live inventory. Shipping documents are being auto-generated (Step 3).
Steps 4 & 5: Invoice & Payment (Accounting)
Step 4: Create Invoice
- Shipping the order automatically triggers the Financial module.
- An invoice is generated and sent to the customer.
- An entry is created in Accounts Receivable (A/R).
Step 5: Receive Payment
- Clerk records payment in the Financial module.
-
⚡ Integration in Action: This single entry...
- Clears the A/R invoice.
- Updates the cash balance.
- Updates the customer's credit status.

Practical Application: O2C in Nepal
Scenario: A Kathmandu-based electronics distributor (e.g., a supplier for Daraz) uses an ERP system.
- Order: A customer in Pokhara orders a laptop via their website (integrated with the ERP's Sales module).
- Integration: The ERP checks the Kathmandu warehouse stock (SCM) and the customer's payment status via an integrated gateway like eSewa or Khalti (Finance).
- Fulfillment: The warehouse team gets the pick order. The ERP suggests the best local courier based on delivery time to Pokhara.
- Visibility 🔍: The sales team in Kathmandu can see the exact moment the laptop is shipped and when the payment is cleared, without making a single phone call to the warehouse or accounting.

🧪 Quick Activity: Which O2C Step and Module?
A bakery wholesaler supplies cafés. For each event, name the step and the ERP module.
- A café orders 200 croissants for Saturday. → Create sales order · Sales
- Bakers get a list of what to pack for the van. → Fulfil order · SCM
- The van driver's delivery note is confirmed. → Ship order · SCM
- The café receives a bill by email. → Create invoice · Finance
- The café's bank transfer arrives. → Receive payment · Finance
Key Takeaways recap
What have we learned about ERPs and the O2C cycle?
- ERPs streamline cross-functional processes by integrating departments onto a single platform.
- The Order-to-Cash (O2C) cycle is a perfect example of an end-to-end process supported by an ERP.
- An action in one module (Sales) automatically triggers actions in others (SCM, Finance).
- This integration provides a single source of truth and real-time visibility across the entire organization.
Discussion Questions 💬
- What problems could occur in the O2C process if a company used separate, non-integrated systems (information silos)?
- Besides Order-to-Cash, what is another cross-functional process that would benefit from an ERP system? (Hint: Think about buying materials).
- How does real-time inventory visibility from an ERP specifically benefit the sales department?
🔁 The Mirror Image: Procure-to-Pay (P2P)
O2C is how a firm gets paid. P2P is how it buys and pays suppliers.
- Purchase requisition: a department requests materials (SCM).
- Purchase order (PO): approved and sent to the supplier (SCM + Finance budget check).
- Goods receipt: the warehouse records what actually arrived (SCM, inventory up).
- Supplier invoice: entered in Accounts Payable (Finance).
- Payment: cash goes out; A/P cleared; ledger updated (Finance).
Same idea as O2C: one entry triggers the next step in another module.
🎬 Watch: Procure-to-Pay in SAP
🧮 Worked Example: The Three-Way Match
Illustrative: a Bhaktapur furniture maker orders sal timber. Before paying, the ERP compares three documents.
| Document | Quantity | Price per cu. ft |
|---|---|---|
| Purchase order | 100 cu. ft | NPR 4,000 |
| Goods receipt | 90 cu. ft | — |
| Supplier invoice | 100 cu. ft | NPR 4,000 |
- ❌ Mismatch: only 90 arrived, but the invoice is for 100.
- The ERP blocks payment of NPR 4,00,000 and allows only 90 × 4,000 = NPR 3,60,000 until the supplier issues a corrected invoice.
- In silos, Accounts might never know the warehouse was short.
