BQE CORE

BQE CORE is an all-in-one project management, time tracking, billing, CRM, and accounting platform for architecture and engineering firms. Most firms are stuck tracking the wrong metrics, or none at all, while the numbers that actually drive profitability stay buried in spreadsheets and disconnected systems. That gets harder to ignore once a firm has grown past a single office, brought on dedicated finance and operations staff, and started running several projects at once. CORE gives firm leaders one place to see the metrics that matter: billing multiplier, effective billing rate, utilization, and realization, in real time. The difference shows up in the numbers. In BQE's 2026 A&E Benchmarking Report, firms with the highest billing multiplier ran profit margins 7.5 points higher and grew revenue twice as fast as the rest of the industry. Thousands of A&E firms use CORE to run more efficient, more profitable practices, so their teams spend less time on manual tracking and more time on the design and engineering work they set out to do.
