Billing and invoicing in architecture and engineering (A&E) firms are more than back-office tasks. They are the financial foundation of project delivery and client relationships. Invoice processing solutions tailored specifically to meet A&E needs improve accuracy, efficiency, and strengthen cash flow.
With Total Synergy, you gain these benefits plus powerful tools to spot common challenges early and implement strategies that help you work smarter, boost profitability, and keep client relationships strong.
What Trips Up A&E Billing (and How to Fix It)
1. Inefficient Invoicing Process Drains Time and Resources
According to The 2025 Architecture & Engineering Industry Benchmark Report, only 51% of A&E firms collect client payments within 31–60 days of invoicing. For many A&E firms, invoicing still relies on spreadsheets, manual calculations, and endless email threads. This process is slow and pulls project managers away from billable work. Over time, inefficient invoicing erodes margins and limits your firm’s ability to grow.
2. Disconnected Systems Create Billing Delays and Lost Revenue
When project management, time tracking, and finance tools don’t integrate and talk to each other, staff are left reconciling data manually. The result can be bottlenecks, delayed billing cycles, and missed charges. Invoicing delays directly translate into delayed payments, which can turn into cash flow headaches.
3. Limited Visibility Into WIP and Outstanding Payments
Without clear visibility into work-in-progress (WIP) and outstanding invoices, your firm risks underbilling, overlooking revenue, or being blindsided by late or missed payments. These gaps can make forecasting unreliable and long-term financial planning difficult.
4. Errors and Rework from Manual Data Entry
Manual data entry can often lead to duplicate charges, omitted billable hours, or misapplied expenses. Even minor mistakes can erode client trust, require extra hours to rework, and extend payment timelines. In a client-driven industry like A&E, invoice errors can cost you much more than time. They can cost client relationships.
How Project Accounting Transforms A&E Invoicing
Project accounting brings time, expenses, and financial data together in one place, giving your firm real-time control over project finances. By linking billing directly to active projects, you gain the accuracy and transparency needed to invoice with confidence and keep cash flow steady.
Unlike generic accounting systems, Total Synergy is purpose-built for the unique workflows of architecture and engineering firms. The platform empowers project managers to generate invoices quickly and with fewer errors, while giving finance teams clear visibility into project performance, margins, and profitability. At the same time, clients benefit from itemised, transparent invoices that build trust and reduce the likelihood of disputes.
Streamlined project accounting also reduces administrative burden by automating repetitive tasks, such as time entry approvals, expense allocations, and progress billing. This means less time chasing down data and more time focusing on delivering exceptional projects. With accurate financial insights at every stage, your firm can forecast revenue more effectively, make smarter business decisions, and strengthen long-term client relationships.
5 Features That Make A&E Invoicing Faster
To truly optimise billing and invoicing, A&E firms need software with functionality tailored to the way they work. These five features make the biggest impact:
1. Customisable Billing and Invoicing
Firms can customise invoice formats, branding, and payment terms to client and project requirements. Consistent, accurate invoices build trust and make payments easier.
2. Quick, One-Step Invoicing Process
Automated invoice creation reduces administrative work and accelerates billing. One-step generation enables project managers to move quickly from approval to client delivery.
3. Flexible Invoicing
Flexible invoicing supports fixed-fee, hourly, milestone, or percentage-of-completion models, ensuring billing matches each contract. Pre-bill invoice drafts let managers review invoices before sending, reducing errors and capturing all billable work.
4. Finance Dashboards
Interactive dashboards provide real-time insights into WIP, outstanding invoices, and overall financial health. With instant visibility, you can track finances, proactively address cash flow issues, and optimise resources.
5. Invoice History Tracking
Invoice history tracking makes it easier to resolve disputes, monitor payment behavior, and maintain transparency with clients. These clear records reduce confusion while strengthening client confidence.
