Bookkeeping and Advisory Services for Sterling Businesses

Monthly bookkeeping, tax prep, and advisory services for Sterling small businesses. Accurate financials and flat monthly pricing from a Fairfax-based team.

Bookkeeping and Advisory for Sterling

Sterling sits at a busy intersection of Northern Virginia’s economy. Between the Route 28 corridor, Dulles Airport, and the steady growth across eastern Loudoun County, the area supports a wide range of businesses from logistics operators to professional service firms to local retailers. What many of them share is a need for reliable financial management without the cost of building an internal accounting department.

That is what we provide. ATS Bookkeeping and Advisory Services is a Fairfax-based firm that handles full-service bookkeeping, payroll, tax preparation, and advisory work for small businesses across Sterling and the wider Northern Virginia region. We work remotely through secure systems with consistent check-ins, so you get responsive support without needing to schedule office visits.

Monthly Bookkeeping

Transaction categorization, bank and credit card reconciliation, and monthly financial statements delivered on a reliable schedule. Your books stay closed every month so you always know where your business stands.

Tax Preparation

Business and personal tax returns prepared by the same team that keeps your books. When your financials are accurate all year, tax season becomes a straightforward process instead of a stressful scramble.

Catch-Up Bookkeeping

If your records have fallen months or years behind, we get them current. We organize the backlog, correct errors, reconcile everything, and then transition into ongoing monthly service so it doesn’t happen again.

Payroll Processing

Full payroll service including direct deposits, tax withholdings, quarterly filings, and year-end W-2s. Your employees get paid correctly and on time. Compliance deadlines are handled without you thinking about them.

Sterling Businesses We Work With

Sterling’s business mix reflects its location. Proximity to Dulles Airport means there are freight carriers, logistics companies, and transportation operators running out of the area. The Route 28 tech corridor brings professional service firms and government contractors. And the residential growth across Cascades, Countryside, and Sterling Park supports a healthy local economy of restaurants, retail shops, and home service providers. We provide Northern Virginia small business bookkeeping services for all of them.

Most of our Sterling clients are doing somewhere between $200K and a few million in annual revenue. Large enough to need professional bookkeeping and real financial reporting, but not large enough to justify a full-time hire. We fill that gap with a dedicated team that knows your books and is available when you have questions.

Transportation and Logistics

Sterling’s proximity to Dulles makes it a natural base for freight carriers, trucking companies, and logistics providers. We handle the fuel cost tracking, fleet expense management, and per-vehicle profitability reporting these businesses need to stay competitive.

Professional Services

Consulting firms, IT companies, law offices, and government contractors operating along Route 28 and throughout eastern Loudoun. We manage overhead tracking, client profitability analysis, and clean P&L reporting that partners and principals can review with confidence.

Construction and Trades

General contractors, electricians, plumbers, and HVAC companies working across Loudoun County and the broader Northern Virginia market. We provide job costing, progress billing support, and the financial documentation needed for bonding and lending.

Retail and Service Businesses

Restaurants, shops, salons, and service providers along Route 7 and throughout Sterling’s commercial areas. We handle sales tax compliance, inventory tracking, and the daily reconciliation that high-transaction businesses require to keep accurate records.

Frequently Asked Questions

Do you work with businesses throughout Sterling?

Yes. We serve businesses across Sterling including along the Route 7 and Route 28 corridors, Sterling Park, Cascades, and the surrounding eastern Loudoun County area. All work is handled remotely so your specific location doesn't matter.

How much does monthly bookkeeping cost?

Full-service bookkeeping starts at $300 per month. Your actual rate depends on transaction volume. We'll give you an exact quote after a short conversation about your business.

Can we meet in person if needed?

Yes. Our office is in Fairfax, a straightforward drive from Sterling. Most clients prefer working remotely because it's faster and more flexible, but we're available for in-person meetings.

My books are months behind. Where do we start?

We start with catch-up work. We organize all the backlogged transactions, fix errors, reconcile accounts, and get you current. Once you're caught up, we move into regular monthly service so it stays that way.

Do you prepare business tax returns?

Yes. We handle S-Corp, C-Corp, partnership, and sole proprietor returns along with personal tax returns. When we've been doing your books all year, the tax return is a natural extension of the work already done.
