Order to cash: the process, where it breaks and where AI helps
Order to cash (O2C) covers every step from a customer’s order until you receive the payment and apply it to their account. For a manufacturer or distributor, it runs through order entry, credit, the promised date, shipping, invoicing, collection and cash application. This guide follows each step, shows where it usually breaks and marks the steps AI can draft for a person to approve.
What order to cash covers
The ASCM Supply Chain Dictionary defines the order-to-cash cycle as everything from a customer placing an order to the payment received and credited. Its stated goal is to turn sales into financial benefit as fast as possible.
Where the cycle starts and ends depends on who draws it. Microsoft’s business process catalog for Dynamics 365 starts order to cash at the order and leaves quotes to a separate prospect-to-quote process. It also places picking, packing and shipping in an inventory-to-deliver process.
In a plant or a distribution business, the shipment sits in the middle of the cash cycle, so this guide keeps it in. ASCM’s description of order management for customer orders also includes order promising, order entry, pick, pack and ship, billing and reconciliation of the customer account.
The order to cash process, step by step
For a manufacturer or distributor that sells on credit terms, the process runs in eight steps.
The first four steps belong to the order desk and the warehouse or plant. The last four belong to accounts receivable. Each hand-off between those teams is a place where an order can wait.
Where each step breaks
Each step has a usual way of failing. The list pairs each failure with the check that catches it at its own step.
- Order. A wrong item, price or unit goes in from the PO and stays hidden until the goods or the invoice arrive. The sales order guide lists the common entry errors and their checks.
- Credit. The warning appears and the order ships anyway. Business Central shows credit warnings at order entry but lets you post past them, so write down who may release an order over its limit.
- Promise. The order desk confirms the requested date without checking supply. Order promising checks stock and planned receipts first, and capable-to-promise works out a date for items you still have to make or buy.
- Fulfil. A short line ships in part, and the customer learns about the rest from the packing slip. Tell them first, with a date, as the backorder guide describes.
- Invoice. The invoice goes out late, or without the customer’s PO number, and their accounts payable team cannot match it. In Business Central, a line ships before it is invoiced, so a shipment posted late delays the invoice as well.
- Collect. Nobody chases an overdue invoice until month end. Business Central can send statements and reminders, also called dunning letters, and it can automate the reminders.
- Apply. A payment arrives with a remittance listing several invoices, or none, and sits unapplied. Payment reconciliation matches the payment text to open invoices, and you can review and change the matches before posting.
- Report. Someone computes days sales outstanding once a quarter, from an export. A weekly figure by customer shows a slow payer while you can still act on the next order.
Which steps AI takes over, with a person approving
AI fits the steps that mean reading documents or matching records. It drafts the work, and a person approves it before anything reaches a customer or posts in the ERP.
| Step | What AI drafts | What a person approves |
|---|---|---|
| Order | Reads the emailed PO, matches each line to your items and prices, and drafts the sales order | The draft order, with every flagged price or item |
| Credit | Summarizes the customer’s balance, overdue invoices and payment history | Releasing an order over the credit limit |
| Promise | Proposes a ship date from stock, open purchase orders and the production schedule | The date sent to the customer |
| Fulfil | Drafts the backorder notice with the quantity shipped and the expected date | The notice, before it goes out |
| Invoice | Compares each invoice with its order and its shipment | Corrections to any invoice that does not match |
| Collect | Drafts reminders and a call list ranked by amount and days overdue | Which customers to call and what to send |
| Apply | Matches payments and remittances to open invoices | The matches, before they post |
| Report | Computes days sales outstanding and overdue balances by customer every week | Credit terms and holds that follow from the numbers |
Microsoft already ships parts of this in Business Central. Its Sales Order Agent drafts quotes and orders from customer emails and does not post documents. Its bank reconciliation assist uses AI to propose matches between bank transactions and ledger entries.
ThriveAI’s order desk automation starts at the first step. It reads each emailed PO, checks it against your items and prices, and drafts the order for a person to approve. Your data is designed to stay at rest on your own server in Canada. Inference runs on that same server with an open-weight model, or through a frontier model under a written zero-data-retention control. Human in the loop explains how the approval step works.
How to measure order to cash
These numbers show how fast your orders turn into cash.
- Days sales outstanding (DSO). ASCM defines DSO as total accounts receivable divided by the average daily sales rate. A company with $36.5 million in yearly sales sells $100,000 a day on average. If it carries $4.2 million in receivables, its DSO is 42 days.
- Cash conversion cycle. BDC, the Business Development Bank of Canada, calculates it as average days inventory plus average days receivable, minus average days payable. The result is how long your cash stays tied up in stock and receivables. Days inventory outstanding covers the inventory part, with a calculator.
- Order to cash time. Measured per order, the cycle runs from the order date to the date the payment is applied. Split it by step to see where orders wait longest.
BDC notes that most companies want to keep average days receivable between 30 and 45 days, and that the right standard depends on the industry. In the example, each day of DSO is $100,000 of cash, so cutting DSO from 42 to 35 days frees about $700,000.
Where to start
Start with the step that holds orders longest, measured on your own records. Pull a few months of orders from the ERP with four dates each: entered, shipped, invoiced and paid. The gaps between those dates show where orders wait.
If most of the wait sits before the shipment, start with the order desk and the promised date. If it sits after the invoice, start with collection and cash application. AI in finance covers the cash forecasts and reports built from the same records.
