A significant amount of cash flow delays occurs before invoices are sent, with 9–18% of earned revenue often remaining unbilled in complex SAP environments, impacting working capital for large enterprises.
Inefficiencies in the billing process, rather than slow-paying customers, are the primary cause of cash flow issues, leading to 5–15 additional days of billing lag and higher Days Sales Outstanding (DSO), which affects overall financial performance.
Organizations can improve cash flow by focusing on Billing Cycle Time, utilizing real-time visibility, structured workflows, and pre-invoice quality checks to reduce disputes and accelerate invoicing processes.
Many organizations focus on improving cash flow by strengthening collections or implementing payment automation. However, a significant portion of delayed cash flow occurs before an invoice is even sent.
Across complex SAP environments, 9–18% of earned revenue remains unbilled at any given time, representing millions—or even hundreds of millions—of dollars in trapped working capital for large enterprises.
The root cause is often not slow-paying customers, but inefficiencies in the billing process itself.
The Hidden Gap in the Order-to-Cash Cycle
The Order-to-Cash process has two key components:
-
Billing Cycle Time (BCT) – the time between completing work and issuing a correct invoice
-
Collection Cycle Time (CCT) – the time between invoice delivery and payment receipt
While collections are influenced by customer behavior, Billing Cycle Time is entirely within an organization’s control. Delays in this stage often come from missing documentation, approval bottlenecks, manual handoffs, or invoice errors that trigger disputes.
In many industries—including energy, manufacturing, construction, and services—these delays can add 5–15 days of hidden billing lag, significantly increasing Days Sales Outstanding (DSO) and slowing cash conversion.
The Financial Impact
Billing delays directly affect working capital and financial performance:
-
9–18% of revenue typically sits unbilled each month
-
5–15% of invoices are disputed due to defects
-
Every DSO day can lock millions in working capital for large enterprises
For example, a $5B organization can have hundreds of millions of dollars tied up in delayed or defective invoices, increasing borrowing costs and limiting the ability to reinvest in growth.
Why Traditional Systems Don’t Solve the Problem
Standard ERP systems like SAP manage orders, deliveries, and invoices, but they often lack visibility into the time and operational gaps between those steps.
Without clear tracking of billing cycle time, organizations struggle to answer key questions:
-
How long does it actually take to convert completed work into an invoice?
-
Where do invoices stall in the process?
-
How much working capital is tied up in billing delays?
Closing the Billing Gap
Improving Billing Cycle Time requires a structured approach that includes:
-
Real-time visibility into unbilled work
-
Structured workflows across operations, field teams, and billing
-
Pre-invoice quality checks to reduce disputes
-
Metrics that measure billing performance, not just collections
By addressing these operational gaps, organizations can accelerate invoicing, improve cash flow, and reduce the amount of capital tied up in the billing process.
