Business Organization & Licensing
Every contractor operates through some form of business entity, and the form you choose affects your personal liability, your taxes, and how you raise money and add owners. This topic covers the main entity types and the general principles of operating a licensed contracting business. These fundamentals are broadly consistent nationwide; specific license classifications, fees, and renewal rules are set by each state.
Estimating & Bidding
An estimate that is too high loses the job; one that is too low loses money. This topic covers how contractors build accurate estimates, the difference between markup and margin, how to compute material quantities, and the common types of bids. The math principles here are universal.
Contracts & Contract Law
The contract defines the deal: what will be built, for how much, by when, and what happens if something goes wrong. This topic covers the elements of a valid contract, common clauses contractors must understand, and how contracts are changed and enforced. These principles come from general contract law and apply broadly across states.
Project Management & Scheduling
Delivering a project on time and on budget requires planning the sequence of work, tracking progress, and communicating clearly among the owner, designer, subs, and crew. This topic covers scheduling tools like CPM and Gantt charts, the concepts of critical path and float, and the documents that keep a project coordinated.
Financial Management & Accounting
Many contractors fail not from lack of work but from poor financial control — running out of cash while waiting to be paid. This topic covers the basic financial statements and ratios, cash-flow realities unique to construction, and job costing. The concepts and formulas here are universal business fundamentals.
Safety & OSHA
Construction is one of the most hazardous industries, and safety is both a legal duty and a business necessity. This topic covers the employer's core safety obligations, the hierarchy of controls, and key federal OSHA requirements that apply on construction sites nationwide, such as fall protection and excavation safety.
Employment & Labor Law
When a contractor hires workers, a web of federal employment and labor laws applies. This topic covers worker classification, wage and hour rules, workers' compensation, and hiring paperwork. The federal baselines here apply nationwide, though states may add stronger protections on top of them.
Building Codes & Permits
Building codes and the permit process exist to protect public health and safety by ensuring structures are built to accepted standards. This topic covers the purpose of codes, the permit and inspection process, and the difference between building codes and zoning. Most U.S. jurisdictions adopt model codes, so the framework is broadly consistent even though local amendments vary.
South Carolina Contracts & Agreements
Contracts and agreements are the most heavily weighted section of South Carolina's Business Management and Law exam. This chapter covers the elements of an enforceable contract, change orders, liquidated damages, and the AIA general conditions.

A sound bid combines the right profit math, correct overhead allocation, and accurate unit pricing. This chapter covers margin, overhead, and the unit-cost method.
South Carolina Financial Groups
South Carolina ties a contractor's bid limit to its financial strength through five Financial Groups. This chapter covers the group bid limits, the Group V thresholds, and how a contractor qualifies and bonds.

South Carolina Labor & Employment
South Carolina imposes a strict work-authorization rule, and worker classification is scrutinized on every job. This chapter covers E-Verify and the employee-versus-contractor test.

Construction materials carry a tax the contractor pays, and federal unemployment tax has a credit that changes the effective rate. This chapter covers sales and use tax on materials and the FUTA rate.
South Carolina Lien Law
South Carolina's mechanic's lien law sets two strict deadlines that a contractor must not miss. This chapter covers the time to file the lien and the time to enforce it.
