St. Charles County is one of the fastest-growing counties in Missouri, northwest of St. Louis on the Missouri River — a base of corporate offices, technology, health care, and retail, anchored by O'Fallon and St. Charles.
We serve businesses across the county — O'Fallon, St. Charles, and the smaller communities in between.
Seven core bookkeeping services, all delivered remotely — designed specifically for the pace and complexity of St. Charles County's growing small business economy.
Your most important financial foundation. We categorize every transaction, reconcile every account, and deliver clean P&L and balance sheet reports to your inbox every month — so you always know exactly where your St. Charles County business stands financially.
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.
Missouri's state sales tax is a low 4.225%, but St. Charles County's local add-ons push combined rates toward 8-11%, and the state income tax keeps falling on annual revenue triggers (top rate now 4.7%, headed for 4.5%). We keep your combined sales tax and books clean.
There's no shortage of bookkeepers in St. Charles County — but most are local firms with hourly billing, slow turnarounds, and outdated processes.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.
