Frequently Asked Questions

My QuickBooks is a mess. Can you fix it without starting over?

In most cases, yes. We can typically clean up and reconcile existing QuickBooks files rather than rebuilding from scratch, correcting miscategorized transactions and catching up missed reconciliations so your books are accurate and tax-ready.

Can you convert QuickBooks Desktop to QuickBooks Online?

Yes. We handle the full Desktop-to-Online conversion process, including chart of accounts setup, historical data migration, and bank and credit card connections, so the transition is seamless rather than something you have to figure out alone.

Does QuickBooks setup look different for different industries?

Yes. A contractor's job costing, a restaurant's POS integration, and a nonprofit's fund accounting each require a different chart of accounts and workflow from day one. We tailor setup to how your specific industry actually operates.

Do you offer ongoing QuickBooks training, or just initial setup?

Both. We provide one-on-one training sessions in person or over Zoom, plus ongoing support and troubleshooting as your business grows and your QuickBooks needs change.

Is your QuickBooks support backed by real accounting expertise?

Yes. Unlike many QuickBooks consultants who are generalists without an accounting background, our support is provided by CPAs who understand both the software and the underlying bookkeeping and tax implications of how your books are set up.
