The business in one offer
Who it serves
Sole proprietors and single-member LLC owners in service trades, such as photographers, consultants or salon booth renters, who stopped categorizing in their accounting software six to twelve months ago and now face a tax filing deadline. They pay because their preparer cannot file from a mess, and doing it themselves keeps slipping.
What to sell first
A catch-up project for up to 12 months of one business checking account and one credit card, with up to 150 transactions per month: categorizing, monthly reconciliations to statements, a profit and loss statement and balance sheet, and a list of open questions for the client's tax preparer. Excluded: preparing tax returns, payroll or sales tax filings, multiple entities, and inventory accounting.
Caps on accounts and transactions let you quote from a quick look at statements instead of a long discovery call. The end point is clear: books reconciled through a date and handed to the preparer. Clients who see clean books often ask for monthly service, which you can quote separately.
What could it cost to start?
This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.
| Item to price | Example allowance |
|---|---|
| Accounting software accountant access and receipt capture tool, three months | $150.00 |
| Secure client document portal and e-signature, three months | $120.00 |
| Bookkeeping certification course or exam fee | $350.00 |
| Professional liability (errors and omissions) quote allowance | $500.00 |
| Second monitor and document scanner | $280.00 |
| Website and engagement letter template | $200.00 |
| Example total | $1,600.00 |
What this assumes—and excludes
Assumes working knowledge of double-entry bookkeeping and at least one common small business accounting program, plus your own computer. Excludes a CPA or enrolled agent credential, tax software, owner pay and local license fees. Price insurance with a carrier that understands bookkeeping services before you sign your first engagement letter.
Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.
How the unit economics work
At an assumed $1,500.00 per cleanup project and $35.00 in direct costs, contribution is $1,465.00 before monthly fixed costs, owner pay and taxes. With 18 all-in working hours per unit, that is $81.39 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.
The example also allows $110.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.
Try your own numbers
These are editable planning assumptions, not prices we have verified. Calculations stay in your browser.
Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 180 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.
How to find the first customers
Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.
- Ask tax preparers and enrolled agents in your area which clients arrive with unusable books each spring. Offer to take those cleanups so the preparer can focus on returns, and agree on a handoff checklist.
- Start outreach in late fall, before the filing crunch. Send a short note to owners in your professional network describing the fixed scope and the date by which you need statements to finish before their deadline.
- Create a sample before-and-after file using an invented business so prospects can see an uncategorized register turn into a reconciled P&L. Show it on calls rather than describing it.
- Offer a free 20-minute statement review that ends with a fixed quote. Track how many reviews convert to projects and adjust your caps if most prospects fall outside them.
What to validate before spending more
- Read the IRS rules on PTINs and confirm that your service stops at the books. If the client wants a return prepared, refer them to a credentialed preparer instead of filling in forms yourself.
- Run one cleanup for a friendly business and time categorizing, reconciling and client questions separately. Use the actual time per hundred transactions to set your caps and price.
- Check whether your state regulates the use of terms like accountant or accounting firm, and choose a business name and title that stay within those rules.
- Test your document intake by asking a pilot client to upload statements through your portal. If they struggle, simplify the instructions before onboarding paying clients.
The operational catch
Clients often have already filed returns for some of the months you are cleaning. Recategorizing those periods can make the books disagree with filed returns. Ask for prior returns at intake, flag differences instead of silently changing closed periods, and leave any amendment decision to the client's tax preparer.
A practical way to fund the first step
Collect half the fee at signing and the balance when the reconciled books are delivered. With software on monthly plans and no inventory, the first deposit covers insurance. Clients who convert to monthly bookkeeping give you recurring revenue to smooth the post-deadline lull.
Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.
Questions before you start
Can I prepare the client's tax return too?
Only if you have a PTIN and meet the other requirements for paid preparers, and even then it is a separate service with its own risks. Many cleanup specialists stay out of returns entirely and build referral relationships with preparers instead.
What if the client mixes personal and business spending?
Agree on a rule at intake, such as coding personal items to owner draws, and list unclear transactions for the client to confirm. Do not guess the purpose of large charges; ask in writing.
How do I price clients over the transaction cap?
Add a per-100-transaction fee above the cap and state it in the engagement letter. Counting transactions from statements before quoting keeps surprises out of the final invoice.
