# System Six

Bookkeeping and CFO help after you take over.

Outsourced bookkeeping, payroll and part-time CFO work, with a service page written for acquisition entrepreneurs specifically. Its own pitch is the month after close: taking over books kept by the seller, closing them on a schedule, and producing statements a lender and an owner can both read.

- Category: Operating Resources
- Pricing model: Custom Pricing
- Where it fits: Operate & Grow the Business
- Website: https://systemsix.com/

## At a Glance

The clearest fit in this category for a buyer inheriting a seller's books, and the one question to ask on the call is what a month costs once the cleanup is done.

## What It Costs

Nothing published. Scope is quoted after a call, which is standard for bookkeeping engagements priced on transaction volume and the state of the books being inherited.

## Best For

A new owner who inherited the seller's bookkeeping and a lender who wants monthly statements

## Pros and Cons

- Pro: The acquisition-entrepreneur page states a client count, a transformation window and a retention figure, which is more than most firms in this category publish
- Pro: Its chief executive bought the firm himself through a [self-funded search](https://searchspheresource.com/glossary/self-funded-search), so the failure it describes is one it has been through
- Pro: Bookkeeping, payroll and CFO advisory come from one firm, which matters when the question is whether the numbers a lender sees are the numbers the owner runs on
- Con: No published pricing, so the engagement cannot be sized before a call
- Con: The figures on its own page are the firm's own, unaudited and undated
- Con: It is a sponsor of the main acquisition podcast, so its name recurs there as advertising rather than as a buyer's account of using it

## What Searchers Say

Named in roughly ninety episodes of the Acquiring Minds archive, mostly in the advertising slot. Its own acquisition-entrepreneur page carries client counts and a retention figure, which are the firm's claims about itself. No independent review at this directory's bar was found.
