Each article in this series provides in-depth insights and practical strategies to help your firm become more profitable. Let's dive into our second topic: managing cashflow in AEC projects.


In the complex world of Architecture, Engineering, and Construction (AEC), profitability is not merely about winning projects and setting judicious fees. It's an intricate dance with that most crucial of partners: cashflow. Poor cashflow management can sink the most promising firms. This article explores strategies for turning financial challenges into steady, predictable cashflow.

The Cashflow Challenge: A Uniquely AEC Predicament

AEC projects, with their long timelines, present a cashflow challenge as substantial as the structures they aim to create. Significant upfront costs coupled with delayed income and payments create a financial balancing act that requires skill and strategy to navigate successfully.

The Lifecycle of Cash: From Outflow to Inflow

Typically, an AEC project's cashflow follows a predictable, if challenging, pattern:

  1. Initial Outflow: An substantial outlay of cash for design, planning, and the first stages of construction.
  2. Gradual Inflow: A steady trickle of progress payments as the project advances.

Below are three different scenarios that have differing impacts on the firms profitability.

The purple line is cost involved over time. The black line is the invoicing There is a small lag when some costs are incurred in setting up and winning the projects, but soon after the billing kicks in and remains ahead of costs incurred.

However, in many jobs, this is what tends to happen. The firm manages to invoice on progress completion against the costs incurred, there is very little margin for error. And if invoices are not paid when due, the firm will need to borrow cash to cover costs.

The final example shows a project where a lot of at risk-work was completed up front over multiple years before anything was invoiced. This is the worst case scenario for most firms and where we don’t want to be - as the firm needs to finance these costs (from borrowings or other projects) until such time that the cash is received.

Understanding this cycle is crucial for effective financial management.

Strategies for Cashflow Mastery: Turning Trickles into Streams

1. The Art of Negotiation: Favourable Payment Terms

In the world of AEC projects, negotiating favourable payment terms is as crucial as the design itself.

  • Front-loaded Payments: Push for larger upfront payments (eg mobilisation fees) to cover initial costs.
  • Frequent Invoicing: Aim for monthly invoicing - related to the cost expended (not just a straight-line drawdown) to ensure sufficient cashflow.

2. Diligent Pursuit: Managing Accounts Receivable

In the realm of accounts receivable, diligence is key to success.

  • Prompt Invoicing: Send invoices promptly as soon as milestones are reached.For example, if 50% of the project is complete, invoice for 50% of the fee to maintain cash flow.
  • Consistent Follow-ups: Establish a systematic approach, where all team members are involved, for following up on overdue payments.
  • Technological Support: Utilise software tools to automate invoicing and payment reminders, streamlining the process.

3. Strategic Outflow: Controlling Accounts Payable

While managing incoming cash is crucial, controlling outgoing cash is equally important.

  • Supplier Negotiations: Negotiate with suppliers and subcontractors for favourable terms, eg “paid-when-paid”.
  • Strategic Timing: Align outgoing payments with incoming cash where possible.

4. Forward Planning: Implementing Robust Forecasting

In the uncertain waters of AEC finances, accurate cashflow forecasting is essential for anticipating and addressing potential shortfalls.

  • Digital Tools: Employ project management software like Fresh Projects to forecast cashflow based on project schedules and payment terms.
  • Regular Updates: Review and adjust forecasts frequently as project details change.
  • Scenario Planning: Prepare for best-case, worst-case, and most likely scenarios to stay ahead of potential challenges.

5. Financial Buffer: Maintaining a Cash Reserve

A cash reserve provides protection against unexpected cashflow challenges.

  • Consistent Savings: Set aside a percentage of revenue, aiming for a reserve of 3-6 months of operating expenses.
  • Credit Backup: Consider establishing a line of credit as a backup, but use it judiciously.

6. Strategic Scheduling: Optimising Project Timelines

Strategic project scheduling can help balance cashflow across multiple projects.

  • Staggered Starts: If possible, avoid having too many projects in the cash-negative stages simultaneously. These tend to be either the very early stages of a job, or the construction stages.
  • Resource Distribution: Distribute resources efficiently across projects - ensuring that you are able to bill across all potential fee-earning jobs- to optimise cashflow.

Conclusion: Cashflow as a Strategic Asset

In the AEC industry, effective cashflow management is more than just financial necessity - it's a strategic tool that can drive profitability and growth. By implementing these strategies and leveraging technology to gain real-time insights, AEC firms can transform cashflow management from a challenge into a competitive advantage.

Remember, healthy cashflow doesn't just keep your business afloat; it provides the resources and flexibility to innovate, expand, and thrive in a competitive market.
