Most architecture and engineering firms have a good idea of how busy they are. But being busy doesn’t always mean being profitable.Â
If work is completed but hasn’t been billed, it’s difficult to know how much revenue is still to come or whether that work will ever be recovered.
WIP reporting closes that gap, giving principals and project managers a clear picture of where money is sitting before it’s invoiced, as well as whether any of it is at risk of never being collected.
What is WIP Reporting in Architecture and Engineering Firms?
WIP, or work in progress, is the value of work your team has completed but hasn’t yet invoiced. In an A&E context, that means time spent on design, documentation, consultant coordination, and other project tasks that have been recorded but haven’t yet made it onto an invoice.
WIP reporting is the process of tracking that unbilled value in real time. It shows you what’s been earned, what’s been billed, and the gap between the two.
Done well, it’s one of the most useful financial signals available to a firm. Without that visibility, principals end up making resourcing and billing decisions without knowing where the firm actually stands.
Why WIP Reporting Matters for A&E Project Profitability
Strong project delivery doesn’t automatically lead to strong financial performance. To stay profitable, your firm needs to turn completed work into revenue as quickly and efficiently as possible.
WIP reporting matters because it surfaces three things that quietly erode margins in A&E firms.
Delayed Billing Weakens Cash Flow
One of the biggest risks is delayed billing. Every day that completed work sits unbilled is another day your firm is funding the project instead of being paid for it. When time is recorded but invoicing is delayed, your firm effectively funds the client’s project between delivery and payment.
According to the 2025 A&E Industry Benchmark Report, 51% of firms collect client payments within 31 to 60 days of invoicing, a pattern confirmed in the 2026 Engineering Industry Benchmark Report as well. A WIP report shows you how much value is sitting in that pipeline and whether any of it is at risk of ageing out.
Unmanaged WIP Increases Write-Off Risk
WIP reporting also helps reduce write-offs. When project teams can see work approaching or exceeding the agreed budget, they can have conversations with clients before additional work becomes unrecoverable. This makes it easier to manage scope changes and avoid unexpected losses, as well as project margin erosion.
Accurate WIP Improves Cash Flow Planning
WIP reporting also improves forecasting and cash flow planning. When firms can see the value of unbilled work across all active projects, itâs easier to forecast when invoices will go out and what your cash position is likely to look like over the coming weeks and months. Revenue forecasting becomes far more grounded when it starts from an accurate WIP position.
What Should an A&E WIP Report Include?
An effective WIP report should provide more than just a total dollar value. The most complete view includes:
Budget Performance by Project PhaseÂ
Compare budgeted costs with actual costs across every project phase. This helps project managers identify budget overruns before they become major financial issues. Tracking against your phase-level budget gives a much clearer picture of project performance.
Billing and Invoice Status Â
Understand exactly where each project sits in the billing process. Has the invoice been prepared, sent or paid? Connecting your invoicing workflow with your WIP data in one integrated system helps ensure completed work doesn’t sit unbilled for longer than necessary.
Realisation RateÂ
This metric measures how much recorded work becomes billed and collected revenue, and is one of the least tracked metrics among both architecture and engineering firms. Monitoring this alongside WIP helps identify opportunities to improve profitability.
Aged WIP
The longer work remains unbilled, the greater the chance it won’t be recovered. Aged WIP can indicate scope disagreements, billing delays, or work that was done but may no longer be recoverable.
Subconsultant CostsÂ
Consultant fees also contribute to your overall WIP position. Tracking these costs alongside internal labour gives firms a complete picture of project profitability. Accurate time tracking across everyone working on the project keeps your financial reporting honest.
Track Project Finances Smarter with Total Synergy
With real-time visibility into your project finances, it’s easier to protect margins, improve cash flow and keep projects on track.
Purpose-built for architecture and engineering firms and headquartered in Sydney, Australia, Total Synergy brings WIP reporting into the same platform where teams record time, manage project budgets, and raise invoices. No exporting to spreadsheets or reconciling figures across separate systems.
When timesheets are linked to project budgets and invoicing happens inside the same platform, your WIP position updates automatically. As a result, project managers can see how much work is ready to invoice, finance teams gain a clear view across the business, and principals have the information they need to make informed decisions without relying on spreadsheets or manual reporting.
If WIP reporting has been a quarterly exercise at your firm rather than an ongoing one, that’s worth changing. Book a demo now to see how Total Synergy supports real-time project financial visibility.
