Spearfish sits at the mouth of Spearfish Canyon in the northern Black Hills — a fast-growing tourism, outdoor-recreation, and college town anchored by Black Hills State University, health care, and a scenic quality of life drawing new residents. Its downtown anchors a small-business economy of hospitality, education services, and retail.
South Dakota is one of the most tax-friendly states in the country — there's no personal income tax and no corporate income tax at all. The state sales tax is a low 4.2% (temporarily reduced from 4.5%), and cities may add up to 2% in municipal sales tax (about 6.2% combined). For Spearfish businesses, there's no state income-tax return to file — the work is keeping sales and municipal-tax records clean, and that's exactly what we do.

Got months or years of backlog? We clean it all up so you can move forward with an accurate set of books — ready for your CPA and ready for decisions.
Starting fresh or inheriting a mess? We configure QuickBooks, connect your accounts, and build a chart of accounts tailored to your industry and business model.
Every account reconciled every month — ensuring your books match your bank statements and every transaction is accounted for accurately.
P&L statements, balance sheets, and cash flow reports that are easy to read, understand, and act on — delivered every month, on time.
We track what you owe and what's owed to you, keeping your cash flow picture clear and your vendor relationships organized.
We ensure payroll expenses hit your books correctly every pay period, syncing with your payroll processor to keep everything reconciled and tax-ready.
There's no shortage of bookkeepers in Spearfish — but most are local firms with hourly billing, slow turnarounds, and outdated processes. Tides was built differently.
We're not a local firm that went remote reluctantly. We were built remote-first from day one, which means faster delivery, better systems, and no overhead passed to you.
One flat rate based on your transaction volume. No hourly billing, no surprise invoices, no "extra work" fees. You know exactly what you're paying every month.
We don't just hand you a spreadsheet. Clean, readable reports with plain-language summaries — so you can make real business decisions from your financials.
Tax season gets dramatically easier when your books are maintained properly year-round. Most clients report lower CPA bills after working with Tides.
We earn your business every month. No lock-in agreements, no early termination fees. If we're not delivering, you can leave. That keeps us sharp.
All plans include monthly P&L, balance sheet, bank reconciliation, and dedicated support. Payroll bookkeeping support available as an add-on.
