Books That Keep Up with Growth
Spearfish businesses are growing quickly, and records often fall behind growth. A builder takes on more projects, a property manager adds buildings, an outfitter adds a second location. Monthly bookkeeping keeps the numbers current so owners can price work, manage cash and file taxes on time. BOMCAS keeps books for Spearfish businesses remotely.
Our bookkeeping page for South Dakota lays out the monthly routine; this one applies it to Spearfish builders, property managers and seasonal businesses.
Each Month
- Reconcile bank, card and loan accounts.
- Match sales and booking reports to deposits.
- Record bills, receipts and accruals.
- Post payroll and match liabilities to deposits.
- Reconcile sales, gross receipts, tourism, county and hotel district balances.
- Deliver financial statements and brief notes.
The 2027 County Tax
From January 2027, Lawrence County's tax needs to be recorded with the other sales taxes, and from July 2027 the state rate changes. We update tax codes, check that registers and booking platforms charge the new rates on the right dates and review the first returns under each change.
Builders and Trades
Construction businesses need job costing that captures materials, labour, subcontractors and equipment for each project, along with retainage, change orders and progress billing. Accurate work in progress at month end shows which jobs are over budget before they finish.
Property Managers and Landlords
Property managers hold owners' rents and tenants' deposits in trust. Their books need trust accounts reconciled monthly, owner statements that match the bank and separate records of management fees. Landlords with several properties benefit from tracking each property separately.
Seasonal Visitor Businesses
Hotels, rentals, campgrounds and outfitters earn much of their revenue in a few months and during rally week. Books that separate deposits for future stays, track each tax and show seasonal margins help owners plan staffing and cash for the quiet months.
Practices and Professional Firms
Medical, dental and professional practices need patient or client receipts, insurance payments and adjustments recorded clearly, with owner draws handled consistently.
Remote and Online Businesses
Online sellers and consultants need sales tracked by state for sales tax thresholds and income tracked by client and location. Marketplace fees and payment processor reports should be reconciled monthly.
Wyoming Work
Businesses working in Wyoming should record revenue and costs for those jobs separately, so Wyoming sales and use tax, unemployment insurance and workers' compensation reports can be prepared from the books.
Guest Deposits and Cancellations
Lodges, cabins and guide services take deposits months before rally week or the summer season. Those deposits are liabilities until the stay or trip happens, and refunds, cancellation fees and platform payouts need to be matched to each booking. Recording them correctly keeps revenue in the right month and the sales tax on the right return.
Restaurants and Breweries
Restaurants, coffee shops and craft beverage businesses need daily sales recorded by category, tips paid out matched to payroll, and food, beverage and packaging costs tracked as a share of sales. Alcohol and food fall under the same gross receipts tax, but inventory and licence costs should be kept apart so margins are clear.
Lender and Investor Reporting
Developers and growing businesses often owe their banks or investors quarterly statements, covenant calculations or construction draw reports. Monthly closes make those reports routine rather than a scramble.
Year-End Package
After December closes, we deliver the adjusted trial balance, fixed asset additions, a list of vendors who need Forms 1099 and the sales and county tax totals, so the business return can begin without another round of clean-up.
Software and Access
We work in QuickBooks Online and other cloud systems, and you keep ownership of the file and full access to your data.

Talk to BOMCAS About Bookkeeping in Spearfish
Each close supports sales and county tax returns, payroll and the business return, plus owners' personal returns, and it makes planning dependable. When records are behind, start with catch-up filing, and businesses with Canadian links should review cross-border tax. Businesses that operate in other parts of South Dakota can use our state guides on business taxes, personal taxes, sales and use tax, payroll, tax planning, late filing and Canada–U.S. tax, which all start from the South Dakota overview.
