Introduction
Put simply, order-to-cash (also known as O2C or OTC in the industry) is the end-to-end cycle from when a customer makes a purchase all the way through to the business collecting payment for it. The process starts the moment a customer places an order and ends when an invoice is settled, recorded, and the data is analyzed.
Having an efficient O2C process can define the success of your business, as well as the relationships you make with your customers. That’s why understanding how O2C works is key to streamlining your processes and upholding your reputation as efficient sellers.
Through this guide, we’ll cover all eight stages of the order-to-cash cycle, providing detailed information around invoicing-through-collections stages, so as an AR team, you can understand how best to alleviate the most day-to-day friction.
What is order to cash (O2C)?
Order-to-cash covers everything in a company’s ordering system - from order placement to cash in the bank, and the sale data eventually being recorded and analyzed.
While a common misconception is that the cycle is completed when a customer pays an invoice or bill, a number of important stages happen after this step, which we’ll go through in detail.
O2C is also often mistaken for other terms, too, such as quote-to-cash (which starts earlier at the quoting and pricing stage) and procure-to-pay (the buyer-side counterpart to the same transaction).
In this guide, we break the order-to-cash process into eight main stages.
The order-to-cash process flow, from order to payment
O2C can be broken into eight main stages:
Order management: The O2C process kicks off with a customer’s order.
Credit management: This assesses a customer’s financial viability to ensure they can afford to make the payment.
Order fulfillment: This is the process of selecting, packing, and eventually delivering the item or service.
Order shipping: The delivery process can involve in-house company shipping fleets or large national postal services.
Customer invoicing: Invoicing and payment can often be automatically generated, providing line items of the order, costs, shipping charges, taxes, or tariffs applied.
Accounts receivable (AR): This stage notes that money is owed to the company, creating a current asset on a balance sheet. It also tracks pace and consistency of payments.
Payment collections: Payment can be collected through cash, bank transfers, wire transfers, checks, online links, mobile payment services, or credit cards.
Reporting and data management: The final stage of the O2C process is collecting, recording, and analyzing the data.
All of these stages are interdependent, meaning they all rely on each other to complete the O2C process. However, any issues that arise may not appear in stage-order - a credit approval issue, for example, could surface later as a collections problem.
Order management to shipping: The operational side
First, it’s important to look at the initial four stages of the cycle - order management, credit management, fulfillment, shipping (stages 1 - 4) - to have a full understanding of the overall process.
1. Order management
Order management begins the entire O2C process, starting the moment a customer places an order. As soon as this order has been placed, the business’s order-to-cash efficiency is then put to the test, with the end result being the recording of data.
Orders can come through multiple types of streams, including:
Phone calls
Emails
Form submission
Online order (eCommerce platform)
Salesperson
2. Credit management
For orders where credit is available, customers are often sent through a credit approval process to ensure they have the funds to make the purchase.
However, this step isn’t essential for all businesses, such as cash-only payment systems or retail businesses that require immediate payment.
As well as evaluating customers for financial security, credit management also establishes guidelines for interest, payment terms or maximum credit allowances, as well as enforcing collections if needed.
3. Order fulfillment
The next stage is the physical process of fulfilling the order, which can often involve:
Warehouse management
Physically packing a product
Providing a service
Quality checks
Updating inventory and stock levels
This stage ensures the customer’s service or product is being prepared, and can then be shipped.
4. Order shipping
Next, the business is responsible for shipping the product to the customer. Delivery processes can often be complicated, especially overseas, so companies use different shipping methods, such as:
In-house company fleets
National postal services
International private shipping services (e.g. FedEx, DHL)
The criteria for this decision include speed of shipping, costs and reliability, so the delivery method you choose to use should be carefully considered to ensure it best fits with your business needs.
Invoicing to cash, where AR picks up the cycle
While the initial four stages are still important, stages 5 - 8 (invoicing, accounts receivable, collections, reporting) are more directly related to AR teams operating through the O2C cycle, so require special attention.
5. Invoicing
A key step in the O2C cycle, invoice generation and payment are often automatically generated in modern systems, but some traditional platforms may require manual invoice requests.
An accurate invoice provides line items including:
Order specifics
Costs
Shipping charges
Taxes
Tariffs applied
Customer data
Due date
Invoicing can also be customized to the business and customers' needs when using the right platform, meaning that this stage can become more efficient through long-term use. Invoicing should be sent out in a reliable timeframe to prevent delays and inaccuracies that can impact the whole O2C chain.
6. Accounts receivable
Accounts receivable (AR) refers to the money owed to the business by customers, and the processes used to collect and manage those receivables.
AR can monitor payments through payment tracking (monitoring incoming payments against the invoices) and reconciliation (matching those payments received to the correct invoices).
Often, systems use automation to ensure the O2C process is running as efficiently as possible, such as automatically sending out payment reminders or notifications for late payments. With the right AR automation platform by your side - like Quadient AR - this stage of the O2C process can be made that much easier.
7. Collections
During this stage, businesses can begin efforts to make the payment collections for invoices past their due date.
Common ways to collect payments include:
Debit cards
Cash
Checks
Credit cards
Wire transfers
Bank transfers
Mobile payment services (e.g., Apple Pay, Google Pay)
If this stage of the cycle isn’t well organized, it can often create a backlog or issues in the O2C process. For example, finding payments that are still overdue, or payments that haven’t been updated in the system and still show as ‘unpaid’, can cause confusion.
That’s why automated software can be extremely beneficial at this step, automatically sending payment reminders, late-invoice notifications, and confirmation emails when payment is received.
8. Reporting
Lastly, the final step of the order-to-cash process includes collecting, recording and analyzing the data of the entire transaction history, such as:
Length of O2C cycles
DSO (days sales outstanding - the average number of days it takes to collect payment after a credit sale)
Perfect order rate (percentage of orders delivered without issues, undamaged and on time)
Forecasting and cash flow
CCC (cash conversion cycle - how long it takes a business to convert its stock into revenue)
CEI (collection effectiveness index - how efficiently a team collects outstanding invoices)
Monitoring these metrics can help you visualize the bigger picture of the order journey, and identify what can be improved in the future.
Due to the nature of these stages directly affecting operating purposes, the rest of this guide will focus solely on the latter half of the O2C cycle, helping your business optimize and streamline its processes effectively.
Why the AR side of the order to cash cycle matters most
But why are stages 5 - 8 the most important for an overall order-to-cash cycle? It’s all in the numbers, the frictions faced when the process isn’t optimal and the potential for reduction in manual workload.
We understand that AR teams may face a number of challenges at this stage in the cycle, including:
High invoice volumes: Leaves more room for human error and an overwhelmed team, which eventually slows down the entire cycle.
Monotonous manual data entry: Costs time and money, especially when dealing with large customer values.
Systems that aren’t integrated seamlessly: Difficult to get a clear, real-time view of who owes what, and when.
Slow dispute resolution: High workloads or lack of efficient processes can cause long dispute cycles, elongating the DSO, and overall losing revenue.
Without the right automation platform at your disposal, these challenges can be amplified, causing overall staff dissatisfaction, bleeding into customer dissatisfaction and a clogged-up O2C process.
All of these challenges can then cause a delayed DSO - for context, the median DSO was 37.5 days in Q2 of 2026 (Source: Credit Research Foundation, https://www.crfonline.org/?p=1827). In this fast-paced world where automation and AI are constantly evolving internal processes, the previous DSO median was 40.1 days in the prior quarter, showing an active shift that needs to be recognized.
The good news is that these are common, solvable problems most AR teams can relate to in their own work, and you can optimize them with the right automation platform.
Common order-to-cash process challenges
While the AR side of the cycle is known to have challenges, that’s not to say the initial stages of the order-to-cash process are free of issues, either.
Some of the most common problems faced across the entire cycle include:
Credit risk and approval delays: Slow approval and inconsistent credit checks can cause delays for order fulfillment, as well as friction for both sales teams and customers.
Data silos between CRM, ERP, and finance systems: Disconnected systems can leave room for human error, with information spreading across teams where no one has a clear shared view of the customer journey.
Manual, error-prone invoicing and data entry: Risks of duplication, billing errors, missing information and out-of-date updates on customer payment progress.
Slow, unclear dispute resolution processes: If disputes lack clear ownership across the team, they can be buried under work, leading to invoice payment delays, customer dissatisfaction and slow cash flow.
Difficulty reporting on O2C performance in one place: If there’s no centralized view of the metrics, businesses may struggle to track performance effectively, identify where the cycle is being held up and make data-driven decisions to improve the O2C process.
How order-to-cash automation helps
That’s where the right order-to-cash automation tools can help put your business in a stronger position than the competition.
Automation can help address a number of the pain points in this process, if not all of them, but can most commonly assist with:
Automated invoicing and payment matching: Helping to reduce manual data entry and avoid human errors.
Centralized, real-time data: Giving AR teams the visibility they don’t typically get from disjointed systems that don’t integrate across the wider team.
Structured workflows: Helping to speed up dispute resolution rates, rather than letting cases sit unmanaged. In turn, this can reduce DSO (meaning the business collects payment faster). This leads to better customer satisfaction and team efficiency.
One thing that’s important to remember is that order-to-cash automation software doesn’t remove the need for good judgment. Instead, it removes repetitive, low-value work so the team can focus on what requires a human, and when.
In short, O2C software can improve day-to-day operations, strengthen customer relationships, and enhance overall brand reputation.
Key takeaways
To summarize everything we’ve covered in the article, the O2C process covers each stage of the cycle from the minute a customer order is received all the way through to collecting and analyzing that payment.
Each of the stages we’ve listed plays an important part in keeping business operations running smoothly, while issues such as payment delays, disputes about payment and manual data entry can cause challenges for teams.
