Clarity Before You Commit.
We believe you should feel informed and confident before choosing a bookkeeping partner. Here are answers to some common questions about how we work and what you can expect.
What industries do you specialize in?
We primarily work with architecture, engineering, and professional service firms. Our team understands the project-driven financial workflows these industries require—and we tailor our bookkeeping, accounting, and software support services to fit them.
Do you only work with firms using Deltek Ajera?
No. While we’re Ajera experts, we also work extensively with QuickBooks Online, QuickBooks Desktop, Statera, and other project-based accounting systems. Whether you're optimizing an existing setup or migrating to a new platform, we can support your team every step of the way.
Can you work with firms outside of Washington State?
Yes! Although we have a strong presence in the Pacific Northwest, we support firms across the United States. Our systems, communication processes, and financial platforms are built to serve clients virtually with the same responsiveness and quality you’d expect from a local partner.
Can InVantage3 help even if our financial systems are a mess?
Absolutely. Many of our clients come to us because their bookkeeping, reporting, or accounting systems aren't working the way they should. Whether you need a cleanup, system optimization, or a complete financial reset, we meet you where you are and build the right foundation for where you're headed.
What’s the difference between your bookkeeping services and outsourced accounting/advisory services?
Bookkeeping covers your day-to-day financial transactions: recording entries, reconciliations, AP/AR management, and financial closes. Our accounting and advisory services go deeper—offering cash flow forecasting, budget planning, financial strategy, and high-level reporting insights to help your leadership team make smarter business decisions.
How quickly can we get started with InVantage3?
Every engagement starts with a free consultation so we can understand your firm’s needs and recommend the right services. After that, onboarding typically moves quickly—especially if you already have accounting systems in place. Most clients are fully operational within a few weeks, depending on the complexity of the project.
