Journal entry examples every consulting owner should understand
Key Takeaways
Every transaction in your books needs a journal entry with equal debits and credits, whether your software creates it automatically or you post it by hand.
Eight entries cover most of what a consulting firm records: invoices, payments, prepaid retainers, subcontractor bills, payroll, prepaid software, owner draws, and month-end adjustments.
A prepaid retainer is a liability until the work is delivered. Booking it as revenue on day one overstates income and leads to costly decisions.
Fix a wrong entry with a correcting entry that reverses and reposts it. Deleting history breaks the audit trail and the month-end close.
Review manual entries every month, match each one to a document, and limit how many people are allowed to post them.
Quick Answer
A journal entry records one business transaction as equal debits and credits across at least two accounts in the general ledger.
Consulting firms rely on a short list: billing clients, collecting cash, handling retainers, paying subcontractors, running payroll, spreading prepaid costs, and recording owner draws.
Give every entry a date, a clear description, and a source document, then review manual entries monthly so mistakes surface before reports reach you.
Picture the owner of a six-person consulting firm, called Harbor Advisory here as an illustration. A client signs a six-month retainer for $24,000 and pays it all on March 3. The bookkeeper records the full amount as March revenue. March looks like a record month, so the owner approves a second hire. In reality, only $4,000 was earned in March, so reported profit was overstated by $20,000.
Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer that catches entries like this one before they reach the owner's reports. This guide shows the journal entries a consulting owner should recognize, with the debits and credits written out, so that a mistake like the March retainer is easy to spot.
What is a journal entry, and why should a consulting owner care?
A journal entry is the basic record of a transaction. It lists the accounts affected, the amount in each, and the date, and the total debits always equal the total credits. Each entry posts to the general ledger, and the ledger feeds the profit and loss statement and balance sheet you use to run the firm.
Accounting software creates most entries automatically when you send an invoice or categorize a bank transaction. The entries you post by hand are the risky ones, because they cover situations the software cannot see on its own, such as prepaid retainers and corrections.
How do debits and credits work in plain terms?
A debit is the left side of an entry and a credit is the right side. Neither means good or bad. They simply increase or decrease different kinds of accounts.
- Assets and expenses increase with a debit and decrease with a credit
- Liabilities, equity, and revenue increase with a credit and decrease with a debit
Cash is an asset, so cash coming in is a debit. A client prepayment you have not yet earned is a liability, so it is a credit.
Which journal entries does a consulting firm record most often?
The figures below are illustrative. Eight entries cover most of the activity in a typical consulting firm.
| Event | Debit | Credit |
|---|---|---|
| Invoice a client for $10,000 | Accounts receivable $10,000 | Consulting revenue $10,000 |
| Client pays that invoice | Cash $10,000 | Accounts receivable $10,000 |
| Client prepays a $24,000 retainer for six months | Cash $24,000 | Deferred revenue $24,000 |
| Recognize one month of that retainer | Deferred revenue $4,000 | Consulting revenue $4,000 |
| Receive a $6,000 subcontractor bill | Subcontractor expense $6,000 | Accounts payable $6,000 |
| Run payroll with $20,000 in gross wages | Wages expense $20,000 | Cash $14,800 and payroll liabilities $5,200 |
| Pay a $12,000 annual software subscription | Prepaid expenses $12,000 | Cash $12,000 |
| Owner takes a $5,000 draw | Owner draw $5,000 | Cash $5,000 |
Three of these deserve extra attention. The prepaid retainer sits in deferred revenue until you deliver the work, and you move $4,000 to revenue each month, as covered in our guide to deferred revenue accounting for retainers. The annual software payment is a prepaid asset that you expense at $1,000 per month. The owner draw is not an expense, because it reduces equity, as explained under owner draw.
What are the most common journal entry mistakes, and how do you fix them?
Most journal entry problems fall into five patterns.
- A prepaid retainer recorded as revenue, as in the Harbor Advisory example
- Personal spending coded as a business expense
- Entries with no description or supporting document
- Entries deleted instead of reversed
- Month-end accruals missing entirely
The fix: for the retainer, post a correcting entry dated in the open period. Debit consulting revenue $20,000 and credit deferred revenue $20,000. March profit drops to its true level, and the deferred revenue balance releases $4,000 each month through August.
The fix: never delete a posted entry. Reverse it with a new entry that references the original, and then post the right one. The history stays intact, and the books still tie to the bank. For period-end entries such as accruals, see our guide to adjusting journal entries.
How should an owner review journal entries each month?
You do not need to read every line. A short monthly review catches most problems.
- Ask for a list of all manual entries posted during the month
- Check that each entry has a date, a description, and a document behind it
- Look closely at round-dollar entries and entries posted on the last day of the month
- Confirm that someone other than the preparer approved the entry
Run this review as part of the monthly close, described in our guide to the month-end close process for service firms. It is the cheapest control a small firm has.
Frequently asked questions
Do I need to post journal entries myself if I use accounting software?
Usually not for routine activity. Software creates entries when you send invoices, record payments, and match bank transactions. Manual entries are for items the software cannot see, such as accruals, reclassifications, depreciation, and corrections. Someone with accounting judgment should post and review them.
What is the difference between a journal entry and an adjusting entry?
An adjusting entry is a type of journal entry made at the end of a period to record revenue or expense in the right month. Examples include accrued wages and the monthly release of a prepaid retainer. Regular entries record transactions as they happen.
Who should be allowed to post manual journal entries?
Keep the list short. The person who prepares an entry should not be the only person who approves it, which is a basic form of segregation of duties. In a small firm, the owner can approve a monthly list of manual entries prepared by the bookkeeper.
In the Harbor Advisory example, the owner paused the second hire, had the March retainer corrected with one entry, and asked for the monthly manual entry list going forward. Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer that produces that list and flags entries that need a second look.
