What do you buy when you buy an accounting practice?
An accounting firm's value sits in its client ledger: the list of clients, what they pay each year and how reliably they come back. Specifically you acquire:
- Recurring compliance fees. Annual tax returns, financial statements, periodic tax filings and payroll compliance that clients need every year.
- Bookkeeping and outsourced finance work. Often billed monthly, which smooths cash flow.
- Advisory and project work. Budgets, restructures and business advice. Valuable, but less predictable.
- Staff. The accountants and bookkeepers who actually prepare the work and talk to clients.
- Work in progress (WIP) and debtors. Work done but not yet billed, and invoices not yet paid.
- Systems and records. Practice software, workpapers, templates and engagement letters.
Accounting practices are often priced against recurring annual fees, with a retention adjustment if clients leave in the first year. Rather than rely on a rule-of-thumb multiple, work out what the fees will earn under your cost base.
What makes a good accounting firm to acquire?
- Recurring compliance makes up most of the fees. Advisory is upside, not the foundation.
- Staff, not the partner, prepare the work. If the retiring partner does every return personally, retention falls when they leave.
- A healthy client profile. A book dominated by retirees winding down their businesses will shrink. A mix of growing small businesses will not.
- Clean lock-up. WIP and debtors collected promptly, with no history of write-offs.
- Compatible software. If both firms use similar cloud platforms, migration is weeks, not months.
- Clients near you or in your niche. The retiring partner's book of clients that look like yours is the ideal target.
What are the due diligence risks when buying an accounting firm?
Beyond the general due diligence red flags, check:
- Client consent and confidentiality. Professional rules often limit how client files move to a new owner. Check the rules of your professional body and state/country.
- Registrations held by individuals. Tax agent or practising registrations may belong to the partner, not the firm. Make sure someone qualified signs from day one.
- Professional indemnity run-off. Claims can arrive years after the work was done. Confirm the seller keeps run-off cover for past work.
- Fee concentration. One family group of entities can look like twenty clients but leave as one.
- Staff restraints and loyalty. A senior accountant who leaves can take clients with them.
- Under-billed WIP. Some partners carry unbilled time that will never be recovered.
Why do accounting firm owners sell?
The most common reason is retirement without succession. Junior staff rarely want to buy the firm, and many partners have spent decades building client relationships they want protected. Others sell because of tax-season burnout, or because keeping up with software, security and regulatory change no longer appeals. These owners usually value continuity for clients and staff over a lump sum, which is exactly what makes seller finance work.
How do the no-money-down structures fit an accounting firm?
Deals combine senior (commercial) debt, seller finance and seller rollover in different proportions:
| Structure | Best fit in accounting | Why it works |
|---|---|---|
| 100% vendor finance | Retiring sole practitioner | The partner is paid from the fees their clients keep paying, so retention risk is shared fairly |
| 70/20/10 | Multi-staff firm with strong recurring fees | Lenders understand recurring compliance income; the seller note can carry a retention adjustment |
| 60/40 | Partner staying on for several years | A 40% rollover keeps the partner introducing clients and signing work |
The retention adjustment is the accounting-specific feature. If an agreed share of fees does not renew in year one, the seller note reduces. That protects the buyer without asking the seller to give up price upfront. Read seller finance explained for how the note itself works.
What synergies come from buying a competing accounting firm?
- Off-season capacity. Most firms have quiet months. Adding a fee base fills them with staff you already pay.
- One software stack. Practice management and tax software licences consolidate.
- Advisory cross-sell. A compliance-only book is often under-served on advisory.
- Shared admin and reception. One front office can serve both client bases.
- Specialist depth. Combining teams lets you offer niche expertise neither firm could staff alone.
Illustrative example: a retiring sole practitioner
Illustrative only. A firm with $2.5M in fees buys a retiring partner's practice billing $700k a year in mostly recurring compliance work, for $750k.
- Funding: 100% vendor finance. No bank. The partner is paid over five years from the acquired fees.
- Retention clause: If less than an agreed share of fees renews in year one, the remaining instalments reduce proportionally.
- Handover: The partner works two days a week for six months and personally introduces the top 50 clients.
- Why it works: The acquired fees are delivered by existing staff, so profit covers the repayments with room to spare. We aim for a DSCR of around 1.5x.
Josh Li, who bought two of his own clinics with 100% vendor finance, says the same lesson applies to accountants: sellers say yes when they trust the person taking over their clients, not when they get the highest number.
If you run an established accounting firm doing $1M+ in revenue and want a signed LOI within 90 days, see if you qualify for an acquisition strategy call.
