The Accounting Industry's Collection Problem

You delivered the business tax returns. You completed the ERTC filing. You reconciled the books. And now the business client won't pay.

Accounting professionals face a unique collection challenge: clients often think the work "wasn't that hard" or dispute fees after receiving the deliverable. Some clients become hostile when they owe taxes or don't qualify for expected credits, and take it out on the CPA by refusing to pay the professional fee.

I work with multiple accounting firms across California. My demand letters for accounting A/R are tailored to the specific dynamics of the relationship between a firm and its business clients.

One limit up front: I handle fees owed by business clients. Fees owed by individuals for personal tax returns or other personal, family, or household matters are consumer accounts, and I do not take those. A licensed collection agency or licensed collection counsel is the route for them, and I can refer you.

Common Accounting A/R Scenarios

ServiceCommon DisputeMy Approach
Business tax preparation"The tax result was worse than we expected"Cite engagement letter + scope of work; the tax outcome is not the CPA's guarantee
ERTC filings"I didn't get approved" or "IRS hasn't processed it"Filing ≠ approval; services were rendered per agreement
Monthly bookkeeping"I didn't use the reports" or "switching firms"Services rendered per contract; work product delivered
Audit preparation"The audit didn't go well"Engagement letter defines scope; outcome is not guaranteed
Business advisory"Your advice didn't help"Advisory services are not outcome-guaranteed; cite engagement terms

How the Debtor Typically Responds (and My Rebuttal)

Debtor's DefenseMy Rebuttal
"The work was substandard"You accepted the deliverable, used the returns, and only raised quality concerns after receiving the invoice
"You're overcharging"Engagement letter specifies rate; time records document hours; no objection raised during engagement
"I'm reporting you to the Board"Regulatory complaints don't excuse payment obligations; I advise client on Board response while collecting the fee
"I'll pay next month"Formal deadline with consequences; convert verbal promise to written commitment
The regulatory threat: Some clients threaten to report the CPA to the state Board of Accountancy as leverage to avoid paying. This is common and rarely successful, but it adds stress. My demand letters address this directly, a regulatory complaint does not extinguish a contractual payment obligation.

Pricing for Accounting Firms

Each business client that owes the firm is a separate demand matter. Attorney demand engagements start at $2,500 per debtor for claims up to about $30,000, after a conflict and scope check. I do not offer volume or per-account collection pricing.

Want me to write it and send it?

I take a business or commercial dispute and write the demand myself, on my letterhead, then handle delivery and read the response you get back.

Request the attorney demand engagement, starting at $2,500

After a conflict check, I draft the demand on my letterhead, prepare the supporting chronology and damages figure, send it by certified mail and email, and review the first substantive response. Sergei Tokmakov, California Bar #279869.

Scope of my practiceI do not take creditor-side consumer-debt collection matters or personal, family or household loan collections. Business-to-business invoices, commercial contracts and payment-platform disputes are what I handle. Regulated consumer collection matters belong with licensed collection counsel, and I can refer you.
