The Bookkeeper Behind Moncada Bookkeeping

I'm Oscar Moncada, and I started Moncada Bookkeeping to give business owners a bookkeeper who keeps their QuickBooks Online file accurate, explains things in plain language, and answers emails.

I have more than 10 years of bookkeeping experience. I also spent more than 20 years in insurance claims, where accurate records, careful documentation, firm deadlines, and clear explanations were part of every file. I bring those same habits to your books.

Today I focus on one platform, QuickBooks Online, and two services: cleanup for books behind or messy, and monthly bookkeeping to keep them current.
