Law firm financing: how solo and small firms fund their practice
Most small and solo law firms finance their practice one of three ways: a bank or SBA term loan (cheapest, but slow and hard to qualify for), a business line of credit (flexible, but usually reserved for firms with strong collateral and credit history), or revenue-based working capital like a merchant cash advance (MCA) or Byzfunder's ByzFlex Flexline (faster and more accessible, priced for the speed and access it provides). Which one fits depends on how fast you need cash, how strong your credit and time-in-business are, and what you're funding — payroll and case costs are different problems than a five-year office buildout.
This guide walks through each option honestly, including where it falls short, so you can match the financing to the actual gap in your firm's cash flow.
One thing up front, because it matters: this article is about financing your law firm's operations — not your clients' cases. Byzfunder does not offer litigation finance, case-specific advances, or lawsuit/settlement funding. Everything below is capital the firm uses for its own business — payroll, marketing, case costs the firm fronts, overhead, or expansion — repaid from the firm's own revenue, not from a settlement or verdict.
- Law firms qualify for financing on firm revenue and deposits, not just personal or business credit score alone
- Banks and SBA loans are the cheapest option but the slowest — often 30-90+ days to fund
- Revenue-based working capital (MCA/ByzFlex) qualifies primarily on cash flow and can fund same-day to 24 hours
- This is business capital for firm operations, never litigation funding tied to a specific case
Why law firms have a financing problem banks don't solve well
Law firms — especially solo and small practices — carry a cash-flow pattern that doesn't map cleanly to how banks underwrite.
Revenue is lumpy and delayed. Contingency-fee firms front case costs (filing fees, expert witnesses, depositions, medical records) for months or years before a case resolves, and even after a settlement, disbursement can take weeks. Hourly-billing firms deal with a different version of the same problem: invoices go out net-30 or net-60, and research on legal industry billing and collections has repeatedly found that firms collect only a fraction of what they bill, with the gap between hours worked and cash collected stretching over months.
Overhead doesn't wait for the case to close. Payroll, rent, malpractice insurance, and case costs are due now, regardless of when a client pays or a settlement lands.
Traditional underwriting is slow and collateral-heavy. Banks and SBA lenders look at time in business, personal credit, tax returns, and often require collateral or a personal guarantee tied to real assets. That process protects the bank, but it doesn't move at the speed a firm needs when payroll is due in five days and a big invoice hasn't cleared.
This is the gap revenue-based funding is built for: it underwrites the firm's actual cash flow — bank deposits and revenue — rather than waiting on a credit committee.
The main ways law firms finance their practice
Bank term loans
A traditional bank term loan is the lowest-cost option if you qualify. You borrow a fixed amount, repay in fixed installments over a set term (often 3-10 years), at an interest rate tied to your credit and the bank's underwriting.
Best for: established firms with strong personal and business credit, multiple years in business, and a clear, one-time use of funds (buying out a partner, opening a second office).
Watch for: approval typically takes weeks to months, often requires collateral or a personal guarantee, and many banks are unfamiliar with how law firm revenue works (trust accounting, contingency timing), which can slow or complicate underwriting.
SBA loans
SBA 7(a) and similar programs are government-backed loans issued through participating banks, with longer terms and competitive rates. They're a strong option for firms making a large, planned investment.
Best for: larger capital needs — office buildout, acquiring another practice, major equipment or technology — where you can wait out a longer approval process.
Watch for: the paperwork and underwriting timeline is the longest of any option here, often 30-90+ days from application to funding, and SBA loans generally require solid credit, financial documentation, and sometimes collateral. If you need working capital for something urgent, SBA is rarely the right speed.
Business lines of credit
A line of credit gives you access to a revolving credit limit you draw against as needed, paying interest only on what you use. It's a good fit for firms that want a standing cushion rather than a lump sum.
Best for: firms with an established banking relationship and strong credit who want flexibility for recurring, moderate cash-flow gaps.
Watch for: approval and limit size still depend heavily on credit and collateral, and banks can reduce or freeze a line during a downturn — right when you'd need it most.
Revenue-based funding (MCA and ByzFlex)
This is capital underwritten primarily against the firm's revenue and bank deposits rather than credit score or collateral. Two structures fall under this umbrella:
- A merchant cash advance (MCA) is a purchase of a portion of the firm's future receivables, priced with a factor rate — it is not a loan and does not carry an APR. Byzfunder purchases a fixed amount of future revenue at an agreed price, and the firm repays through a percentage of daily or weekly deposits, which flexes with cash flow. Read more on how a merchant cash advance works.
- ByzFlex is Byzfunder's revenue-based revolving capital — the ByzFlex Flexline — which gives a firm ongoing access to capital tied to its revenue performance, replenishing as the firm generates deposits. It is not a line of credit; it's a distinct revenue-based product. See revenue-based financing for the full breakdown.
Best for: firms that need cash fast — payroll, marketing spend, case costs the firm is fronting, bridging a slow collections period — and would rather qualify on deposits and revenue than wait on a credit-driven underwriting process.
- ✓Funds same-day to 24 hours once approved
- ✓Qualifies primarily on firm revenue/deposits, not a high credit score or collateral
- ✓Repayment flexes with daily/weekly revenue instead of a fixed bank-style schedule
- ✗Cost of capital is higher than a bank or SBA loan, reflecting the speed and accessibility
- ✗Not structured for large, long-horizon capital projects (a decade-long office build is a better fit for SBA)
Law firm financing options compared
| Funding type | Qualifies on | Speed | Best for | Watch for |
|---|---|---|---|---|
| Bank term loan | Credit history, collateral, financials | Weeks to months | Established firms, planned one-time capital needs | Slow approval, collateral/personal guarantee often required |
| SBA loan | Credit, financials, business plan | 30-90+ days | Large investments (buildout, acquisition) | Longest timeline, heavy documentation |
| Business line of credit | Credit history, banking relationship | Days to weeks | Recurring, moderate cash-flow cushions | Limits/access tied to credit; can be reduced in a downturn |
| Revenue-based funding / ByzFlex | Firm revenue and bank deposits | Same-day to 24 hours | Payroll, case costs, marketing, bridging slow collections | Higher cost of capital than bank/SBA options |
How to think about the real cost of each option
It's tempting to rank these options purely by rate, but that misses what each one is actually solving for.
A bank or SBA loan's low rate assumes you can wait for it. If the loan takes 60 days to fund and your payroll gap is next week, the "cheaper" option didn't solve your problem — it just declined slowly. The real cost of a bank loan includes the weeks of stress, the loan officer follow-ups, the financial statements you had to compile, and the risk that you miss the window entirely.
A line of credit's flexibility depends on it staying open. Banks can and do reduce or freeze lines of credit during periods of stress in a borrower's industry or their own balance sheet — which is exactly when a firm is most likely to need it. A line you can't draw on isn't really a cushion.
Revenue-based funding's cost reflects speed and access, not opacity. An MCA's factor rate (say, 1.2–1.5x the amount advanced, repaid as a percentage of daily deposits) is higher than a bank loan's APR because it's underwriting risk differently — deposits and revenue trend, not a decade of tax returns and a lien on firm assets. For a firm that can't wait, or doesn't have collateral to offer, that's the actual trade-off: pay more for speed and access, or wait weeks and hope the numbers still work when the money arrives.
The honest way to frame it: match the tool to the timeline. A five-year office lease buildout is a bank/SBA problem. A payroll gap in ten days is a revenue-based funding problem. Using the wrong tool for either one costs more than the rate difference suggests.
What law firms actually use financing for
Firms that turn to working capital are typically covering:
- Payroll and staff costs during a slow collections stretch
- Case costs the firm fronts in contingency matters — filing fees, expert witnesses, discovery costs — as part of normal firm operations
- Marketing and client acquisition, especially for practice areas with long sales cycles (personal injury, family law, immigration)
- Bridging the gap between billing and collection on hourly matters
- Expansion — hiring an associate, opening a satellite office, adding a practice area
Note the pattern: every one of these is a firm-level business expense, not a specific case's litigation cost being financed against its eventual outcome. That distinction is the line between working capital and litigation finance, and it's worth being precise about it.
What Byzfunder looks at when a law firm applies
Because revenue-based funding underwrites the business rather than a specific asset, the application process looks different from a bank's. Byzfunder generally reviews:
- Recent bank statements showing deposit volume and consistency — this is the core signal, since repayment is tied to ongoing revenue.
- Time in business — newer firms can still qualify; this factors in alongside revenue, not as a hard cutoff.
- Personal credit (FICO) — a floor of 525 for MCA and 550 for ByzFlex, well below what most bank underwriting expects.
- Basic firm information — entity structure, ownership, and how the funds will be used.
There's no requirement to disclose case files, client matters, or settlement details, because the underwriting isn't tied to any individual case — it's tied to the firm's operating account. That's a structural difference from litigation finance, where the case itself is the collateral.
Working capital vs. litigation funding: they are not the same product
It's an easy mix-up, so it's worth stating clearly: Byzfunder's funding is working capital for the law firm's business — not litigation funding tied to a specific case.
Litigation finance (also called legal funding or lawsuit funding) is a separate, specifically regulated product where a funder advances money against the expected outcome of a specific case, typically repaid only if and when that case settles or wins, secured by the case itself. It's usually structured as a non-recourse investment in the case outcome.
What Byzfunder offers is different in structure and purpose: capital advanced against the firm's overall revenue and deposits, used for the firm's general operations, and repaid from the firm's ongoing business activity — not from any single case's proceeds. If you're looking for capital tied to a specific matter's outcome, this isn't that product, and you should work with a dedicated litigation funder instead.
How the Federal Reserve and legal-industry data back this up
Two independent data sources point at the same underlying pattern small law firms live with every week:
Put together: the financing gap solo and small firms feel isn't anecdotal — it shows up in both the Fed's broad small-business data and the legal industry's own billing/collections research.
Bottom line
If you can wait weeks to months, have strong credit and collateral, and need capital for a large planned investment, a bank or SBA loan is the cheapest way to finance your firm. If you want a standing cushion and already have a solid banking relationship, a line of credit can work. But if you're a solo or small firm dealing with the reality of lumpy, delayed collections — payroll due before the invoice clears, case costs piling up before a settlement lands — revenue-based funding like an MCA or the ByzFlex Flexline is built to move at that speed, underwriting your firm's actual cash flow instead of asking it to wait. And to be clear one more time: this is capital for the firm's business, never for a specific case or settlement.

FAQ
How do law firms typically get financing? Most small and solo firms use one of three paths: a bank or SBA term loan, a business line of credit, or revenue-based working capital (MCA or ByzFlex) that qualifies on the firm's revenue and bank deposits rather than credit alone.
Can a new or solo law firm get funded? Yes — revenue-based funding options generally weigh current business revenue and deposit activity more heavily than time in business, which makes them more accessible to newer or solo firms than a traditional bank loan, where several years of financials are typically expected.
What credit score does a law firm need? For a Byzfunder merchant cash advance, the minimum FICO is 525; for ByzFlex, it's 550. Traditional bank and SBA loans generally expect a stronger credit profile and a longer credit history.
How fast can a law firm get funded? Revenue-based options like an MCA or ByzFlex can fund same-day to within 24 hours of approval. Bank loans typically take weeks; SBA loans often take 30-90+ days.
What's the difference between working capital and a traditional loan? A traditional loan is borrowed money repaid on a fixed schedule with interest (APR). An MCA is a purchase of future receivables priced with a factor rate — not a loan — and ByzFlex is revenue-based revolving capital, not a line of credit. Both repay based on the firm's ongoing revenue rather than a fixed monthly payment tied to a rate.
Is this litigation funding or lawsuit funding? No. Byzfunder's financing is working capital for the law firm's business operations — not an advance tied to a specific case's outcome or settlement. Litigation finance is a separate, distinct product that Byzfunder does not offer.
What can law firms use the funds for? Common uses include payroll, marketing and client acquisition, case costs the firm fronts as part of normal operations, bridging gaps between billing and collections, and expansion like hiring or opening a new location.
Does a law firm need collateral to qualify? Bank and SBA loans typically require collateral or a personal guarantee. Revenue-based funding like an MCA or ByzFlex is generally underwritten against the firm's revenue and deposits rather than requiring hard collateral, though terms vary by application.
