At Elaxtra Advisors, we work with technology services executives and management teams as their businesses evolve. A common shift is moving from traditional time-and-materials (T&M) models toward fixed-fee, milestone-based, subscription, and managed-service arrangements. These models can change the commercial profile of a business, but they also require corresponding changes in how revenue is recognized.
Under a pure T&M model, billing and revenue recognition generally align closely with hours delivered. As companies introduce fixed-fee projects, milestone billing, upfront deposits, or recurring contracts, the relationship between billings and recognized revenue becomes less direct. Understanding this distinction is important for accurately managing the company’s financial statements.
The key distinction is that invoicing and revenue recognition are separate events and do not necessarily occur at the same time. Billing schedules may be structured around cash-flow considerations, such as upfront deposits or milestone payments. Under US GAAP (ASC 606), however, revenue is generally recognized as the underlying performance obligations are satisfied rather than when an invoice is issued. The difference between billing and revenue recognition is reflected through several balance sheet accounts.
Deferred revenue (a liability). When a company bills or collects cash before delivering the underlying services, such as through a 50% upfront deposit, the amount is generally recorded as deferred revenue. The liability is recognized because the company still has an obligation to deliver the contracted services. As those services are provided, the deferred amount is recognized as revenue. Recording upfront billings as revenue before the related work is delivered can overstate both revenue and profitability.
Unbilled revenue (a contract asset). The opposite situation can occur when a company performs work before it has the contractual right to issue an invoice. On fixed-fee or milestone-based projects, revenue may be recognized as performance obligations are satisfied even though billing occurs later. In these cases, the amount may be recorded as a contract asset rather than accounts receivable. Once the relevant billing conditions are met, the balance can be reclassified to accounts receivable.
Accounts receivable and cash complete the billing cycle. Issuing an invoice generally creates an accounts receivable balance, while collecting that receivable converts it into cash. Neither event, by itself, determines when revenue is recognized.
A fixed-fee engagement can therefore involve several stages: an upfront deposit increases deferred revenue; delivery of the services results in revenue recognition and reduces the deferred balance; work performed ahead of a billing milestone may create a contract asset; reaching the milestone generates an invoice and accounts receivable; and collection converts the receivable into cash. Revenue follows the delivery of the underlying services, while billing and cash collection follow the contractual payment schedule.
The implications extend beyond accounting. Gross margin, EBITDA, and ultimately business valuation depends on appropriately recognized revenue. Recognizing revenue based on billings rather than performance can result in overstated profitability and create adjustments during financial diligence. Establishing appropriate revenue recognition practices early can improve financial reporting, planning, financing processes, and transaction readiness.
As organizations evolve in their commercial models, their accounting processes should evolve accordingly. A clear revenue recognition policy, regular tracking of deferred and unbilled revenue, and a reconciliation between billings and recognized revenue can provide greater visibility into the company’s financial performance and support more consistent reporting.
