Frequently Asked Questions

You've got questions. We've got answers.

Answers to common questions about our services, billing, and how we work.

What types of businesses do you work with?
We work with sole proprietors and corporations — including service providers, consultants, trades, and online sellers. Our clients include retail and e-commerce businesses, yoga studios, wellness clinics, real estate agents, contractors, restaurants and cafés, hair salons, and more. Whether you're just getting started or managing a growing operation, we’ll tailor our services to fit your needs.
Why choose a dedicated bookkeeping service like Castle?
We’re built for small business owners who want to stay in control. With weekly updates to your books, real-time reporting, and flat-rate pricing. We help you stay compliant without paying CPA-level fees. While accountants often update books your books quarterly or annually, we keep your numbers current — so you can make better decisions, borrow with confidence, and grow smarter.
How much do your bookkeeping services cost?
Our flat-rate packages start at $200/month for sole proprietors and $450/month for corporations with employees or more complex needs. Pricing depends on the size of your business, and transaction volume.
What’s the difference between catch-up and clean-up bookkeeping?
Catch-up bookkeeping gets you up to date if you’ve fallen behind — for example, if months of records are missing. Clean-up bookkeeping fixes errors in existing books that may be disorganized or inaccurate. We offer both during onboarding or as a one-time service.
Is everything handled remotely?
Yes! Castle is fully digital. You’ll receive automated reminders and upload your documents through secure platforms. You can manage everything from your home, office, or even while traveling.
Will I have a dedicated bookkeeper?
You’ll be supported by our team rather than just one person. Our system-based approach means if someone is away, your file is still covered — with no disruption to your service.
Do you require a contract?
At Castle Bookkeeping, we keep things simple and flexible. All of our services are offered on a month-to-month basis with automatic renewal — no long-term contracts, no surprises. You can pause or cancel anytime with 30 days’ notice. We believe great bookkeeping should earn your trust every month.
Can you work with my current bookkeeping software?
We exclusively use QuickBooks Online to provide consistent, efficient service and maintain the highest quality standards across all client accounts.
