"Amy Lunn of Margin Bookkeeping has been an absolute lifesaver for our organization's fiscal records. As a small nonprofit primarily funded by government grants, having clean and current books is critical to maintaining trust from our funders. When she started supporting us, we were behind by about 7 months, with a pretty tight deadline to get our books up to speed. She dove in immediately, navigating complex government payment schedules, billing, and reporting with ease. As a result we were able to get our books together on time and successfully passed the funder's audit! Throughout she was communicative, responsive, and above all focused on meeting our needs. We look forward to continuing to work with Amy and Margin!
