About Giersch Group

Bookkeeping, accounting and consulting for owners in Milwaukee, Wisconsin, come from the Giersch Group, a family-run firm. It works with family businesses, small enterprises, franchises and nonprofit organizations, and says that it draws most of its clients from southeast Wisconsin while serving businesses anywhere in the country virtually.

Bookkeeping and reporting that a CPA can use

Bookkeeping is the core of the work. The firm says it produces, reviews and manages a client's books on a full accrual basis, so that the owner can see the financial position of the business at any time. The records it prepares are intended to be ready for a CPA's review, and the firm also handles tax compliance, payroll and audit support.

The firm offers guidance on the difference between an accountant, a bookkeeper and a CPA, which it says helps owners choose the right kind of help. Day-to-day tasks such as check writing for accounts payable and collections calls for accounts receivable are included in the service.

Management consulting for owners who want a clearer picture

The consulting work starts with a business analysis that looks at strengths, weaknesses, threats and opportunities. The firm says it then presents information on financial systems, business strategy, optimal cash reserves, internal organization and technology, with recommendations the owner can act on.

The firm also reviews business models, market positioning, cash flow management and operating structure. Its stated aim is to help owners see how each business decision will affect their finances before they make it.

Virtual CFO and controller support

For businesses that need financial leadership but not a full-time hire, the firm provides outsourced CFO and controller services on a virtual or interim basis. These cover financial reporting, modeling and budgeting, and setting up a QuickBooks system along with online accounting services and training for the client's staff.

Support for startups and family-run firms

The firm supports startups and young businesses with consulting, accounting and HR services that it describes as affordable for companies at an early stage. It describes its approach as getting to know the owner's goals first and then tailoring the bookkeeping and consulting to fit.

The family business services address succession, communication and decision-making, and the firm says it understands these issues because it is itself a family business. It has served more than 700 clients over the past decade, according to its site.
