Big Accountants provides accounting advisory services to US businesses that have outgrown the way their finance function was first set up. We review how money, data and approvals move through your business, find what is slowing you down or putting you at risk, and help you put the fixes in place.

Accounting consulting works best when the advisers also do the work. Our team runs bookkeeping, controller and CFO engagements every month, so our recommendations are practical, sized for your business and tested in real closes, not lifted from a template.

Typical advisory outcomes
  • A faster, documented month end close
  • A chart of accounts that answers real questions
  • Controls that close obvious gaps
  • A software stack that fits your volume
  • Clear profitability by product and customer

FAQ

Accounting Advisory Services FAQs

What are accounting advisory services?

Accounting advisory services help a business improve how its finance function works. They cover processes, internal controls, chart of accounts design, systems selection, profitability analysis and preparing financial information for lenders, investors or buyers.

How is advisory different from bookkeeping or tax preparation?

Bookkeeping records transactions and tax preparation files returns. Advisory looks at how the whole finance function works and recommends changes that make it faster, more accurate and more useful for decisions.

Do you implement your recommendations?

Yes. We can put the changes in place ourselves, such as redesigning your chart of accounts or setting up approval workflows, or support your team while they do it.

How much do accounting consulting services cost?

Cost depends on the scope, the size of your finance function and the implementation support you need. We price advisory per project, hourly or as a fixed monthly fee, quoted in writing after a free call.

Do you give legal or tax advice?

We give accounting and finance advice. Legal questions are referred to your attorney, and tax positions are handled by qualified tax professionals, either our tax team or your own preparer.

Can you help us prepare to sell the business?

Yes. We clean up historical financials, prepare supporting schedules and organize the information buyers and their accountants usually request during due diligence.

How long does an advisory project take?

A diagnostic review usually takes two to four weeks. Implementation projects typically run one to three months, depending on scope.

Which industries do you advise?

We advise ecommerce, healthcare, retail, wholesale, manufacturing, restaurant, construction, real estate and accounting firm clients across the US.
