Most AEC firms stall at key growth stages where outdated people, processes, and technology can no longer support scale.
At BQE, we talk to thousands of architecture and engineering firms of all sizes every year. These conversations have taught us that A/E firms rarely experience growth as a smooth curve. Instead, they tend to hit distinct management breakpoints. At these breakpoints, the people/process/technology that once worked begin to break down or fail.
Recognizing these inflection points and responding with intention can be the difference between sustainable growth and ongoing chaos. Firms need to address the right challenges at the right times to succeed.
This is our take on the different breakpoints and the challenges to solve (and some thoughts on how technology can help solve them).
1-5 employees: The founder-driven firm (65% of A/E firms)
The majority of A/E firms begin – and then remain – at this stage. Firms this size have the benefit of speed and flexibility. So why do most firms never escape this stage?
- Limited financial clarity. “I look at my bank account at the beginning of the year and then again at the end of the year, and that tells me if it was a good year.” While cash flow may feel manageable, there is too much uncertainty and ambiguity from project to project. There is minimal planning, and no real sense of profitability as a business.
- Memory and Excel. Proposals, contracts, projects, and invoices live in an individual person’s memory or a manually updated Excel file. This can lead to errors, delays, wasted time, and missed opportunities for the firm.
- Volatility. There is inherent volatility for firms at this stage. The firm might be relying on one project coming through to hire or hold on to a couple of employees. Revenue is unpredictable as projects start and stop.
At this stage, starting to build better financial visibility and simple processes can help establish some repeatability and visibility for decision-making before complexity starts to increase.
5-20 employees: The transitional firm (20% of A/E firms)
Eighty-five percent of A/E firms have fewer than 20 employees, meaning this stage can be a difficult one to escape. Firms at this stage start to stagger under the weight of inefficiencies and often need to better identify what’s driving success (or holding them back from achieving it). Challenges here include:
- Growing inefficiencies. Firm leaders start to spend too much of their time tracking project statuses, getting invoices out the door, collecting payment for those invoices, etc. Complexity increases not linearly but exponentially, so buttoning up basic processes becomes a must.
- Project status. Many firms lack real-time visibility into the performance of a given project or even the ability to easily report on its status. Budget overruns and timeline delays become more common as the attention of leadership is pulled in too many directions. Client satisfaction can start to take a hit at a time when building a happy client base is essential.
- Project performance. Many firms can’t answer the question, “What was my margin on project X?” Without timely, trusted data on each project, firms might be focusing their attention on projects, or clients, or segments that are a drain on the business rather than highly accretive. There may be a better sense of firm-wide performance, but that view doesn’t trickle down to project-level accounting.
At this stage, tools to streamline invoicing and provide strong project-level data become essential to help firms control the chaos and break the 20-employee barrier that holds so many back.
20-100 employees: The scaling firm (10% of A/E firms)
At roughly 20 employees, A/E firms also need to start building for specialization and scale. Some of the most substantial challenges at this stage:
- Resource allocation and forecasting. Firm leaders can no longer look across the room and know what everyone is working on. Nor can they intuitively forecast whether a project can be staffed appropriately. The level of complexity increases substantially.
- Standardization. With an expanded team, firm leaders and project managers can no longer march to the beat of their own drums. Without standardized processes, firms struggle to maintain quality and scale. Further, leadership needs to be looking at the same set of metrics to continue to manage and improve the business.
- Specialization. Firm leaders can no longer wear as many hats as they once did. We often see firms starting to hire their first true finance, BD, marketing, or operations leaders at this stage. While specialization in roles at a firm is necessary, it presents its own hiring and management difficulties.
To address these challenges, firms need to invest heavily in building out their reporting and analytics and ensure the distribution of information and reports to the right people. Further, firms should invest in training their staff on how to best analyze data and use it to improve performance on an individual, project, and firm-wide level. Improved project planning and staffing tools lead to better project delivery and reduce staff burnout while helping manage margins.
100+ employees: The optimizing firm (5% of A/E firms)
Leaders of firms with more than 100 employees have moved beyond managing projects and teams. They are now managing an enterprise. Complexity is no longer operational alone; it is strategic, financial, and organizational.
- Strategic decision-making. Should the firm double down in the healthcare market? Should they expand into education? What should hiring look like for the next year? These are all big questions requiring standardized, trusted, and often timely information that many firms lack even at this scale.
- Governance, risk, and data integrity. Financial controls, audit readiness, security, and data accuracy become critical. Informal workarounds that once felt acceptable now introduce real operational and reputational risk.
- Organizational. As the number of functions grows and the size of each function expands, often across multiple offices, alignment and accountability become difficult. Firms often lack the right processes and tools to standardize processes and metrics as they scale further.
At this stage, firms are investing in larger finance, ops, or IT functions to get more out of their firm management systems. They are often exploring integrations (moving to more of a best-of-breed versus best-in-class paradigm) to get more efficiency and insights out of their systems.
Final thought
Firms are often too slow to invest in the infrastructure required to scale. At the same time, building for too much scale too early can be equally damaging, consuming resources before the firm is ready to absorb added complexity.
The data underscores how difficult this balance is. Roughly 85% of A/E firms never reach 20 employees, and 95% remain below 100. Growth is rarely limited by opportunity alone. More often, it is constrained by whether a firm’s people, processes, and systems evolve at the right moments.
Across thousands of conversations with A/E firms, clear patterns emerge in how operational, financial, and project challenges change with scale. To help firms better understand where they sit on this curve, we created a Firm Maturity Index that benchmarks key business indicators across stages of growth. It is designed as a diagnostic, not a scorecard, and can serve as a practical reference for leadership teams looking to align on priorities and make more intentional decisions about what to improve next. The Firm Maturity Index is available here: Firm Maturity Index.
