Demand letters for CPAs, bookkeepers, and tax preparers with unpaid invoices from business clients
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.
| Service | Common Dispute | My 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 |
| Debtor's Defense | My 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 |
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 $2,500After 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.
