Side-by-Side
What Is the Difference Between Invoice Factoring and a Line of Credit?
Seven dimensions that matter to CFOs, controllers, and business owners making this decision. No asterisks, no hidden qualifications.
AR Funding
Time to Funding
Based On
Balance Sheet
Covenant Risk
Commitment
If Customer Can't Pay
Cost Transparency
Invoice Factoring (Sigma)
Set up in 24–48 hours, then invoices funded the same day
Mainly your customers' creditworthiness
No debt added — a sale of receivables, not a loan
None — doesn't trigger bank covenants or require financial reporting
12-month standard term, with a trial period available on request. No usage minimums: factor only the invoices you choose.
By default you replace the invoice. Optional credit insurance covers a customer who doesn't pay.
One fee per invoice, set by how long your customer takes to pay. The schedule is in your agreement before you sign.
Bank Line of Credit
Weeks to months — underwriting, committee review, covenant setting
Your business credit score, financials, and operating history
Debt appears on balance sheet; affects debt-to-equity ratios
May include covenants on revenue, EBITDA, working capital, or debt ratios — violations can trigger early repayment
Annual renewal common. Unused portions may have fees. Commitment expected.
—
Interest rate disclosed upfront, but total cost depends on utilization and duration — can be difficult to model accurately
Same Invoice, Same 45 Days
What Each Costs on a $100,000 Invoice
One $100,000 staffing invoice that your customer pays in 45 days, funded two ways. The factoring figures come from our capital estimator. The bank line's interest is a hypothetical dollar figure; yours depends on your bank's terms.
| Invoice factoring (Sigma) | Bank line of credit | |
|---|---|---|
| Cash on day one | $85,000 advance | $85,000 drawn, if it fits under your credit limit |
| What it costs | $3,525 fee, calculated on the full invoice | About $1,000 in interest (hypothetical), plus any annual, unused-line or renewal fees |
| When your customer pays | Your customer pays Sigma $100,000. Sigma releases the $15,000 reserve minus the fee: $11,475 | You repay the $85,000 plus interest |
| You keep in total | $96,475 | About $99,000, before bank fees |
| If next month's invoices double | Funding grows with the invoices you submit | Capped at your limit until the bank approves an increase |
| What it takes to qualify | Mainly your customers' credit. Set up in 24–48 hours | Your financials, operating history and often covenants. Weeks to months |
A bank line usually costs less, if you can get one and stay within its limit. Factoring costs more per invoice and fits when the bank says no, the line is maxed out, or your sales are growing faster than the limit.

After You Qualify
What Happens Next
Once you submit your application, here's exactly what to expect — with real timelines.
Scenario 01
Submit your application
5-minute form. No financial statements, no tax returns. Just basic business info and the invoices you want to factor.
Scenario 02
Human review
A licensed underwriter — not an algorithm — reviews your invoices and your customers' credit.
Scenario 03
Funded the same day
Setup typically takes 24–48 hours from signup. After that, invoices you submit are funded the same day, straight to your operating account.
Honest Assessment
When a Line of Credit Might Be Better
We include this section because a CFO doing real due diligence will see through one-sided content immediately. If a line of credit is the better fit for your situation, you should know that — and we'd rather tell you than have you find out later.
When LOC May Win
You need working capital for expenses not tied to a specific invoice.
Factoring advances against invoices you've already issued to B2B customers. If you need capital for payroll bridging, inventory purchases, equipment, or operating expenses that aren't tied to a receivable — a line of credit's flexibility fits better. Factoring is an A/R tool, not a general-purpose credit facility.
When LOC May Win
Your bank line is available, healthy, and unconstrained.
If your bank line has ample availability, no covenant pressure, and a rate structure that works for your margin — use it. Factoring is designed to be additive and complementary, not a forced replacement. Many of our clients use both: their LOC for general operations, factoring to accelerate specific large receivables or bridge peak A/R periods.
The Sigma Difference
Credit Risk Protection Options
Recourse factoring is our standard structure and costs the least. Add credit insurance to protect against a customer who doesn't pay, including one that goes bankrupt. Our professional team can guide you through your credit risk options.
No personal credit reports
Your customers' credit carries the most weight.
Off-Balance Sheet
Factoring is a sale of receivables, not a loan — it doesn't touch your bank covenants or balance sheet.
Exit flexibility built in
We can structure your agreement to include a clean migration clause if your bank line opens back up.
One transparent fee per invoice
Shown in full before you sign. No utilization fees, no draw fees, no surprises.
