Construction accounting & bookkeeping built for St. Louis contractors
FinTruction provides construction accounting and bookkeeping in St. Louis for general contractors, subcontractors, concrete companies, HVAC contractors, roofers, electricians, plumbers, and specialty trades operating across the bi-state STL metro. Our construction accounting and bookkeeping services include job costing, WIP reporting, retainage tracking, bi-state tax compliance, historic renovation cost tracking, AIA billing support, and monthly financial reporting tailored to the St. Louis construction market.
Construction companies in St. Louis operate in a bi-state metro area with major federal projects, healthcare facility expansion, historic renovation activity, and innovation district development. Generic small-business bookkeeping cannot address the financial complexity of running a construction company across the MO-IL border.
Our contractor bookkeeping services in St. Louis keep your financial records clean, reconciled, and ready for CPA review. We understand the cash flow patterns of bi-state construction companies and maintain your books to account for projects spanning the Missouri-Illinois border.
Every construction platform claims to have a "QuickBooks integration." Most break the moment your books need to be accurate. Sales tax mismaps, retainage disappears, change orders create duplicates, and job costing reports stop matching project reality. We fix the integration so your software, your books, and your job‑level numbers all tell the same story.
Also work with Foundation, Sage 100, Bill.com, ADP, Gusto, Ramp, and more. See all platforms we integrate →
St. Louis contractors work across a mix of federal facility builds, healthcare expansion, historic renovation, innovation district development, and residential construction. We build job costing systems that capture labor, materials, equipment, and subcontractor costs at the project level so you always know which jobs are making money.
Accurate WIP schedules are essential for St. Louis contractors seeking bonding capacity increases, bank financing, or accurate year-end financial reporting. We prepare Work in Progress reports that compare estimated costs to actual costs and identify underbillings and overbillings across your project portfolio.
Retainage balances can tie up significant working capital for St. Louis contractors, especially on larger commercial, federal, and institutional projects. We track retainage at both the receivable and payable level by project and contract, monitor release schedules, and ensure your balance sheet accurately reflects held funds for lender and bonding reviews.
St. Louis contractors face a complex tax landscape spanning Missouri and Illinois. Our construction tax planning services manage bi-state income tax obligations, the St. Louis earnings tax, sales tax differences between states and municipalities, historic tax credit documentation, and proper employee withholding based on work location.
Growing construction companies in St. Louis need more than monthly bookkeeping. Our controller services and CFO services provide the financial leadership that mid-size contractors need to grow their bonding capacity, manage cash flow across bi-state operations, and make strategic decisions on project selection and equipment investment.

They didn’t just record transactions and call it a day. They built a custom chart of accounts around how a remodeling company actually runs, did a full catch-up on years of bookkeeping inside QuickBooks Online, and now stay on top of my monthly bookkeeping and payroll. Every step, they broke it down in simple terms instead of burying me in accountant talk.

St. Louis is experiencing a significant construction resurgence driven by federal investment, healthcare expansion, innovation district development, and historic renovation activity. The National Geospatial-Intelligence Agency (NGA) West campus in north St. Louis is one of the largest federal construction projects in the Midwest, creating work for hundreds of contractors across multiple trades and generating economic development in surrounding neighborhoods.
The Cortex Innovation Community in the central corridor has transformed a formerly underutilized area into a thriving technology and research district, with ongoing construction of lab space, office buildings, mixed-use developments, and supporting infrastructure. BJC HealthCare and Washington University Medical Center continue to invest in facility construction and renovation, creating steady demand for contractors experienced in healthcare construction.
St. Louis has one of the largest inventories of historic buildings in the country, and adaptive reuse projects converting former warehouses, schools, and commercial buildings into apartments, offices, and mixed-use spaces are a major segment of the local construction market. These projects often leverage federal and Missouri state historic tax credits, which require careful cost tracking and documentation to maximize credit value.
For contractors operating in the St. Louis metro, the bi-state nature of the region creates unique financial challenges. Projects may cross the Missouri-Illinois border, employees may work in both states, and tax obligations differ by jurisdiction. FinTruction provides the construction accounting expertise that STL contractors need to manage these complexities while maintaining accurate job costing and financial reporting.
Bi-State Prevailing Wage Requirements: Contractors working on public projects in the St. Louis metro must comply with prevailing wage laws in both Missouri and Illinois. Missouri rates are set by the Missouri Department of Labor and Industrial Relations, while Illinois rates are determined by the Illinois Department of Labor. Federal projects such as the NGA West campus require Davis-Bacon prevailing wages. FinTruction tracks applicable rates by jurisdiction, trade, and county and prepares certified payroll reports for each authority.
St. Louis Earnings Tax: The City of St. Louis imposes a 1 percent earnings tax on income earned within city limits. Construction companies performing work within the city must withhold and remit this tax on employee wages and report net profits from projects within the city. Our accounting systems track project locations and allocate revenue and labor costs to ensure proper earnings tax compliance.
Historic Tax Credit Compliance: Contractors working on historic renovation projects in St. Louis may need to track qualifying rehabilitation expenditures for federal and Missouri state historic tax credits. Proper cost segregation between qualifying and non-qualifying work is essential to maximize credit value. FinTruction structures job costing to capture these cost categories and provides the documentation needed for tax credit applications.
Missouri Mechanics Lien Law: Missouri's mechanics lien law allows contractors, subcontractors, and material suppliers to place liens on properties when they are not paid for construction work. Specific notice requirements and filing deadlines apply, and the requirements differ from Illinois lien law for contractors working on both sides of the border. FinTruction helps STL contractors maintain the records and documentation needed to protect payment rights in both states.
Multi-State Workers Compensation: Missouri and Illinois have different workers compensation systems with different rates, classifications, and reporting requirements. Contractors operating across the state line must maintain proper coverage in both states and track labor costs accordingly. Our accounting systems ensure workers compensation costs are properly allocated to projects and reported by jurisdiction.
