“Can a 30-year-old A&E vertical SaaS become the financial operating system (payments, payroll, accounting) for architecture and engineering firms?”
BQE evolved from a time-billing tool (BillQuick, 1995) into a vertical SaaS firm-management platform for architecture and engineering firms, especially after acquiring ArchiOffice and EngineerOffice in 2009. Under Serent Capital ownership since 2021, it has layered embedded finance products — BQE ePayments (ACH + card acceptance via a PayFac model) and Gusto-powered embedded Payroll — into its CORE platform to deepen wallet share with A&E firms.
BQE processes payments through BQE ePayments (self-operated). Disclosed money-movement rails: ACH.
BQE connects to bank accounts through Plaid.
BQE's payroll is powered by Gusto Embedded.
BQE integrates with QuickBooks, Xero and MYOB.
The Embedded Finance Index 2026 maps 5 layers in BQE's stack: Payments / PSP (BQE ePayments (self-operated)); Money movement (ACH); Payroll (Gusto Embedded); Open banking (Plaid); Accounting (QuickBooks, Xero and MYOB).
BQE was founded by Shafat Qazi and is founded in 1995, headquartered in West Hollywood, CA, United States.
BQE's acquisitions include ArchiOffice (2009) and EngineerOffice (2009).
