§ About
A small studio, on purpose.
Twelve people, one office on Mercer Street and 340 clients we know by name. We stay small so that the person who answers your email is the person who knows your books.

Our story
2014 —
Margot Ellery spent nine years doing tax for companies with finance departments. She noticed that the businesses who needed good advice most, the bakeries, studios and two-person startups, were the ones least likely to get it.
Double Entry opened with four clients and one rule: the books are closed by the 10th, every month, no exceptions. Twelve years and 340 clients later, the rule hasn’t moved. Neither has our habit of explaining every number in a sentence anyone can follow.
We’re licensed in New York and file in all fifty states. Most of our clients never visit the office. The ones who do get very good coffee.
Three principles
Debits on the left. Credits on the right. Everything else, in plain English.
No. 02
Explain the number
Every report comes with a sentence about what changed and why. If we can’t explain it simply, we haven’t finished.
No. 03
Answer the same day
A real accountant replies within four business hours. Our median last quarter was under three.
The people
Who keeps your books.
Every client has one named lead from this list, backed by a CPA who reviews every return.

Margot Ellery
CPA · MST
Nine years in Big Four tax taught Margot two things: small businesses get the least attention, and the best advice arrives before the year ends. She started Double Entry to fix both.

Theo designed the close process every client runs on. He believes most accounting problems are really filing problems, and has a label maker to prove it.
