CEO Executive AssistantBilling and collections are among the most operationally important financial functions in a consulting firm. In a services business, revenue is recognized when work is delivered, but cash arrives only when invoices are paid. The gap between these two events, multiplied across a portfolio of engagements, creates working capital requirements that the firm must manage actively. Poor billing and collections management has caused the collapse of otherwise healthy consulting businesses that ran out of cash despite strong revenue.
For the consulting CEO, delegating billing and collections effectively means building a system that ensures invoices are accurate and timely, that collections are pursued consistently and professionally, and that cash flow is managed proactively, all without the CEO personally chasing late payments or reviewing every invoice.
The Billing and Collections Process
Billing and collections in a consulting firm involves several sequential activities.
Engagement setup. When a new engagement begins, the billing terms should be established in the contract and communicated to the finance function: billing cycle (monthly, milestone-based, or project-end), rate structure, expenses policy, and payment terms.
Time and expense tracking. Consultants record their time and expenses against engagement codes. The accuracy of this tracking determines the accuracy of invoicing.
Invoice generation. At the defined billing trigger, the finance function generates an invoice based on the tracked time, expenses, and the contract terms. The engagement manager reviews and approves the invoice before it is sent.
Invoice delivery. The invoice is sent to the client contact designated in the contract, typically the finance or accounts payable contact.
Payment tracking. The finance function tracks invoice payment against due dates and generates aging reports.
Collections follow-up. When invoices are not paid by the due date, the finance function follows up with the client according to the defined collections protocol.
Dispute resolution. When clients dispute an invoice, the account lead and finance function work together to resolve the dispute.
Write-offs. When invoices cannot be collected, the CFO approves write-offs above a defined threshold.
Delegating Each Billing and Collections Activity
Engagement setup. The engagement manager is responsible for ensuring that billing terms are correctly captured in the contract and communicated to finance. Finance is responsible for setting up the engagement in the billing system.
Time and expense tracking. Individual consultants are responsible for accurate and timely time and expense recording. The engagement manager is accountable for ensuring their team complies. The finance function runs exception reports to identify incomplete or late submissions.
Invoice generation. The finance function generates invoices. The engagement manager reviews and approves invoices before they are sent. This is a shared responsibility: finance ensures accuracy; the engagement manager confirms the invoice reflects the actual work delivered and resolves any discrepancies.
Invoice delivery. Finance sends invoices to the designated client contact. The account lead may choose to send a courtesy notification to their primary client contact for major invoices.
Payment tracking and collections follow-up. Finance owns this process. The collections protocol defines the timing and approach for follow-up: reminder emails at defined intervals, escalation to the account lead if payment is significantly overdue, and CEO involvement only for specific circumstances.
Dispute resolution. The account lead manages any client disputes that arise, working with finance to understand the billing basis and with the engagement manager if the dispute involves the substance of work delivered.
For a framework on how billing delegation connects to the broader finance governance model, the consulting CEO delegation resource provides context.
Designing the Collections Protocol
One of the most important tools for delegating collections is a clear, documented collections protocol. This protocol should specify:
Day 1 (Invoice sent). Invoice delivered to client with clear payment terms.
Day 31 (First reminder). Finance sends a polite reminder to the client’s billing contact.
Day 46 (Second reminder). Finance sends a second reminder, slightly more direct.
Day 61 (Account lead escalation). Finance notifies the account lead, who follows up directly with the primary client contact.
Day 76 (Senior escalation). The account lead engages the practice lead or senior partner. For significant amounts, the CEO is informed.
Day 91+ (CEO involvement). For invoices that remain unpaid beyond 90 days with no resolution in sight, the CEO engages directly or a formal dispute resolution process is initiated.
This protocol ensures that collections happen consistently without requiring CEO involvement in routine follow-up. The CEO’s involvement is reserved for genuinely difficult situations.
Billing Accuracy as a Delegation Requirement
Many collections problems begin as billing accuracy problems. Clients who receive inaccurate invoices, whether overbilled or billed for work they did not expect, dispute the invoice rather than paying it. Reducing billing disputes begins with improving billing accuracy.
Engagement manager invoice review. The engagement manager’s review of each invoice before it is sent is the primary quality control mechanism. They check that the invoice reflects the work actually delivered, that expenses are within the agreed policy, and that there are no timing or calculation errors.
Regular billing alignment conversations. For ongoing engagements, the account lead should periodically confirm with the client’s finance contact that the billing approach is working as expected. This catches any potential disputes before they occur.
Clear engagement setup documentation. Many billing problems arise from ambiguity in the original contract: unclear billing triggers, unexplained rate differences, or disputed expense scope. Clear, detailed engagement contracts reduce these problems at the source.
Cash Flow Monitoring and CEO Oversight
Even with fully delegated billing and collections operations, the CEO should maintain visibility into the firm’s cash flow and accounts receivable position.
Weekly cash position. The CFO provides a brief weekly update on the firm’s current cash position and any significant upcoming payments or receipts.
Monthly accounts receivable aging report. A report showing all outstanding invoices by client, age, and amount. The CEO reviews this report to identify any significant delinquencies or trends that require attention.
Monthly collection rate tracking. What percentage of invoiced amounts are being collected within the payment terms? A declining collection rate is a leading indicator of a billing or relationship problem.
The consulting delegation guide provides additional context on how financial delegation supports the firm’s overall commercial health.
Common Billing and Collections Delegation Failures
CEO as default collections escalation. When account leads routinely bring billing disputes to the CEO rather than handling them within their authority, the CEO becomes the de facto collections manager. Define the account lead’s authority to resolve billing disputes and enforce it.
Time recording that is consistently late or inaccurate. Consulting firms with poor time recording cultures produce inaccurate invoices and lose revenue to unbilled work. The CEO should set clear expectations about time recording timeliness and accuracy, and enforce them through the performance management process.
Billing delays at engagement close. When engagements conclude, the final invoice is often delayed while the delivery team moves on to the next project. Define a deadline for final invoicing after engagement close-out and track compliance.
Disputes allowed to age without resolution. Billing disputes that are not actively managed tend to become write-offs. The account lead’s responsibility includes resolving disputes promptly, not just logging them.
Conclusion
Billing and collections delegation is about building the operational processes, authority structures, and monitoring mechanisms that ensure the firm collects what it earns without the CEO personally managing invoice follow-up. The CEO maintains strategic visibility through cash flow monitoring and accounts receivable reporting, and engages directly only when collections situations require executive judgment.
The consulting CEO who invests in building a strong billing and collections system creates one of the most direct improvements to the firm’s financial health: better cash flow, lower bad debt, and more of the revenue earned actually arriving in the bank.
