Middlesex County is the most-populous county in New England — home to Harvard, MIT, and the Kendall Square biotech cluster in Cambridge, the Route 128 tech corridor in Waltham, and the affluent and MetroWest communities of Newton, Somerville, Lowell, and Framingham.
We serve businesses across the county — Cambridge, Lowell, Newton, Somerville, Framingham, Waltham, and the smaller communities in between.
Seven core bookkeeping services, all delivered remotely — designed specifically for the pace and complexity of Middlesex 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 Middlesex 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.
Massachusetts businesses in Middlesex County pay a flat 5% state income tax — with a 4% surtax on income above roughly $1 million — and collect a flat 6.25% state sales tax that has no local add-on anywhere in the state. Corporations also owe the state's corporate excise. We keep your income, sales, and corporate-excise records clean.
There's no shortage of bookkeepers in Middlesex County — but most are local firms with hourly billing, slow turnarounds, and outdated processes.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.
