The short verdict
For most professional services firms, the best working-capital loan is a line of credit or overdraft that covers the gap between doing the work and getting paid. Buying a fee book, client list or partnership share suits a term loan sized on the earnings being bought. Consultancies billing large clients can also use invoice finance. Never borrow to fund partner drawings the firm hasn't earned.

Loans for accountants, lawyers and consultants are business finance for firms that sell expertise rather than goods: covering the gap between doing work and being paid, buying a fee book or client list, funding a partner buy-in, or fitting out an office. The best loans for professional services firms recognise that the firm’s most valuable asset is its stream of fees, not anything a lender can repossess.
Where does cash get stuck in a professional firm?
In two places: work in progress and debtors. Hours are worked and recorded, but they only become an invoice at a milestone or month end. Then the invoice waits for the client to pay. For a firm billing larger organisations, that can mean the fees for work done in March arrive in May.
Meanwhile, the firm’s costs don’t wait:
- Salaries for professional staff, paid fortnightly or monthly.
- Rent and technology, including software subscriptions that add up fast.
- Tax instalments, BAS and PAYG withholding on their own timetable.
- Partner drawings, which partners often expect at a steady rate regardless of collections.
Slow payment is a real pressure. The Payment Times Reporting Regulator’s January 2026 update found that 68.2% of small business invoices from large businesses were paid within 30 days in the first half of 2025, which leaves roughly a third waiting longer. For a consultancy with a few big clients, a single late payer can stretch the whole month.
What do lenders want from a professional services firm?
Lenders assess the quality of your fees. They’ll look at:
- Fee history. Several years of financials showing stable or growing billings.
- Client concentration. One client making up a big share of fees is a risk.
- Debtor ledger. How old your receivables are, and how reliably clients pay.
- Recurring work. Annual compliance work, retainers and ongoing matters are valued highly.
- The partners. Their experience, the partnership agreement and personal positions.
For law firms, lenders will be careful to separate office accounts from trust accounts. Trust money belongs to clients and never supports the firm’s borrowing.
Which loans are best for accountants, lawyers and consultants?
Four structures, graded for an established firm on our judging criteria:
| Facility | What it funds | Fit | Flexibility | Cost all-in | Paperwork | Security needed |
|---|---|---|---|---|---|---|
| Line of credit or overdraft | WIP and debtor gap | Strong | Strong | Fair | Strong | Fair |
| Acquisition term loan | Fee book, client list, buy-in | Strong | Fair | Fair | Weak | Fair |
| Invoice finance | Large-client receivables | Fair | Fair | Fair | Fair | Fair |
| Unsecured term loan | Fit-out, technology, hiring | Fair | Fair | Fair | Strong | Fair |
1. Our pick for working capital: a line of credit or overdraft
The gap between work done and fees collected comes back every month, so it needs a facility you can draw and repay repeatedly. A line of credit or overdraft, sized on your billings and debtor book, is the natural fit. Our line of credit versus overdraft verdict explains how to choose between them.
2. Our pick for growth by acquisition: a term loan sized on earnings
Buying a retiring practitioner’s fee book or a share of a partnership is paying today for fees over many years. A term loan sized on those fees, with a term that lets the acquired income repay it, is the right shape. Larger deals often involve property security. Our verdict on buying a business walks through the process.
3. Worth a look: invoice finance for consultancies
When most of your fees come from a handful of large, creditworthy clients on 30 to 60 day terms, invoice finance can release cash as soon as you bill. It suits engineering, IT and management consultancies more than firms with many small clients, and some financiers are wary of legal fees that can be disputed.
4. For defined projects: an unsecured term loan
A new office fit-out, a practice management system or a planned hiring round has a defined cost and a defined benefit. A fixed-term unsecured loan suits it, provided the term doesn’t run past the benefit. Our hiring staff verdict covers financing new roles.
Our verdict
Accountants, lawyers and consultants: where we land
- Best for
- A line of credit or overdraft for the gap between work and payment, and an earnings-based term loan for fee-book purchases and partner buy-ins.
- Not for
- Funding partner drawings the firm hasn't yet collected, or financing a long-term acquisition on short-term, high-cost money.
- Check before you sign
- Line fees on the full limit, review dates and conditions, clawback terms in any fee-book purchase, and total dollars repayable on acquisition loans.

Illustrative example: an accounting firm buys a fee book
Illustrative only. A two-partner accounting firm with steady recurring fees agrees to buy a retiring accountant’s fee book for $450,000. The book’s clients are mostly small businesses with annual compliance work. The sale includes a clawback if clients leave in the first year.
- Purchase: a term loan of $350,000 over five years, sized on the acquired fees and supported by a partner’s property for part of the amount.
- Deposit: $100,000 from the firm’s reserves.
- Integration costs: the firm lifts its line of credit by $50,000 to cover extra staff during the first tax season, when the new clients’ work is done but not yet billed.
- Clawback: the firm negotiates for any clawback refund to reduce the loan balance directly.
Verdict for this firm: a term loan for the purchase, a line of credit for the integration gap. Funding both through the line would have left it permanently drawn and unavailable for normal swings.
How much can a professional firm borrow?
Working-capital limits are usually set on billings and the strength of the debtor book. Unsecured, cash-flow and line-of-credit facilities for trading businesses typically fall between $5,000 and $500,000, with the higher end reserved for established firms whose deposits are large and regular. Acquisitions are different: the loan is sized on the fees being bought, and bigger deals generally lean on property, where property-secured business loans run from $20,000 to $5,000,000 against residential or commercial security. Lenders also weigh client concentration, so a firm with fifty steady clients may be offered more than one of similar size reliant on two.
Why shouldn’t a firm borrow to fund partner drawings?
Because it hides a problem rather than solving it. If partners draw more than the firm collects, borrowing to fill the gap simply moves the shortfall into debt, with interest added. The sustainable fix is aligning drawings with collected fees, tightening billing and chasing debtors faster. A facility should smooth timing, not fund a permanent overspend. Our cash flow verdict has more on telling the two apart.
How can a firm shrink the borrowing it needs?
The cheapest working-capital loan is the one you avoid by billing faster. Firms that invoice at milestones rather than at matter end, request deposits on large engagements, offer simple online payment and follow up overdue accounts promptly often find their facility barely gets drawn. Reviewing your debtor ledger monthly, and knowing which clients pay late every time, also lets you price slow payment into your fees. If you own your rooms or are considering it, our commercial property verdict covers premises finance.

Questions owners ask
How do accountants finance buying a fee book?
Usually with a term loan sized on the recurring fees being acquired and the expected client retention, sometimes supported by property for larger purchases. Lenders want the vendor's fee history, the sale agreement and any retention or clawback terms. A deposit from the buyer strengthens the application.
Can a law firm borrow against work in progress?
Not directly in most cases, but lenders do consider the firm's billing history and debtor ledger when setting a line of credit or overdraft limit. Trust money is not available to the firm and can't be used to support borrowing. Keep office and trust accounts strictly separate in any application.
Is invoice finance good for consultants?
It can be, particularly for consultancies billing government agencies or large companies on 30 to 60 day terms. The financier advances most of each invoice's value when you issue it. It suits firms with a few large, reliable clients more than firms with many small accounts.
How do I fund a partner buy-in?
Most incoming partners use a personal or business term loan sized on the share of profit they're buying, often with property security. Lenders review the firm's financials, the partnership agreement and how capital accounts work. Repayments are usually funded from the new partner's share of drawings.
Should a professional firm use an overdraft or a line of credit?
Both cover short gaps. An overdraft is linked to your transaction account and suits day-to-day swings, while a line of credit is a separate facility you draw and repay. Compare the fees on the full limit, how each is reviewed and how easily you can reduce it.
