Accounting built around how engineering firms operate
Project-based accounting, tax planning, and advisory support built for engineering firms across the greater Sioux Falls, SD area, including Hartford
Quick answer
Buss CPA is a CPA firm serving Hartford and Sioux Falls, South Dakota, offering tax preparation, outsourced accounting, and advisory services built for project-based engineering firms. Services include fixed-fee outsourced accounting with job costing by project, entity and personal tax planning, and partner compensation advisory, all backed by secure online access to financial data.
Engineering firms don't run on a normal invoice cycle. Progress billing, retainage, multi-phase contracts, and project timelines that stretch across fiscal years complicate the numbers in ways a generic bookkeeper rarely anticipates. Buss CPA works with engineering firms and professionals across the greater Sioux Falls area, with offices in Hartford and Sioux Falls, who need an accounting partner that understands project-based revenue recognition and the cash flow gaps that come with it.
We handle the accounting so you can focus on your business, which for an engineering firm means fewer hours reconciling change orders and more time on the work that actually pays the bills: design, site visits, client relationships. Whether you run a two-person civil engineering practice or a firm with several project managers billing across multiple jobs at once, the accounting needs to keep pace with what's happening on the ground, not lag two months behind it.
Tax preparation and planning for engineering firms and professionals
Engineering firms face tax questions a general preparer often misses. Entity structure alone changes the math: an S-corp election can reduce self-employment tax exposure for a principal engineer, while a multi-partner firm structured as a partnership needs its own guaranteed payment and basis tracking. Buss CPA prepares both business and personal returns for engineers and engineering firm owners, and the two conversations rarely stay separate.
Deductions specific to professional service firms, equipment and software depreciation, vehicle use for site visits, home office allocations for firms with remote staff, only pay off when they're planned for before year-end instead of discovered in March. That's the difference between personal income tax preparation done reactively and a proactive strategy that accounts for quarterly estimates, retirement contributions, and entity-level decisions throughout the year. Firms that wait until filing season to think about taxes typically pay more than they should. Buss CPA reviews tax positions on an ongoing basis, so surprises get caught in October, not April.
Outsourced accounting for project-based engineering firms
Tracking profitability by project is where most engineering firms lose visibility. A job that looks profitable on the invoice can be underwater once labor hours, subcontractor costs, and overhead allocation get factored in. Buss CPA's outsourced accounting services give engineering firms a fixed monthly fee and a full back-office function built for project-based work.
What that includes:
Job costing tracked by project, so you know which contracts are actually profitable
A fixed monthly fee, no surprise invoices for routine bookkeeping work
Cash flow reporting that accounts for retainage and progress billing timelines
Payroll processing built around salaried engineers, hourly drafters, and contract staff
Accounts payable and receivable managed on a predictable schedule
Monthly financial statements delivered through
Advisory support for growing engineering practices
Growth in an engineering firm usually forces partner-level decisions: bringing on a new principal, changing how profits get split, or figuring out what a founder's exit looks like in five or ten years. Those conversations need a financial picture that's current, not a set of books closed out last quarter.
Buss CPA's advisory work with engineering and professional service firms covers partner compensation structures and the financial strategy behind expansion, whether that's opening a second office or adding a specialty practice area. The goal isn't a one-time recommendation. It's an ongoing relationship where financial data informs decisions as they come up, not after the fact. Firms that treat advisory as a standing conversation tend to handle partner transitions and growth decisions with fewer surprises than firms that call an accountant only at tax time.
