Gaithersburg is one of the most diverse business communities in Maryland, from the shops and restaurants of Kentlands and Rio to the biotech and IT firms along the I-270 technology corridor to the trades businesses that keep Montgomery County running. Quanterra Financial gives those owners accurate books and a clear view of where the money is going.
Every month we categorize transactions, reconcile accounts, and deliver financial statements that are ready for your tax preparer, your lender, or your own planning. When something looks off, you hear about it from us first.
Serving Gaithersburg and Upper Montgomery County
We are based in Bethesda and work with owners throughout Gaithersburg, Germantown, Montgomery Village, and Clarksburg. Most of that work happens through QuickBooks Online and a monthly call, with in-person meetings when they are useful.
Home service providers are a specialty. Plumbers, HVAC companies, landscapers, cleaners, and remodelers have seasonal cash flow, job costing, and equipment purchases that a generic bookkeeper often gets wrong. We set the books up so you can see margins by job and plan for the slow months.
Founder Romeo Traettino is a QuickBooks Gold ProAdvisor and former audit professional. That background is why our clients describe our work as meticulous.
