How AR Funding Works
Capital Against Your Receivables Confidentially
AR funding is a revolving credit facility where Sigma advances against your accounts receivable without notifying your customers. You submit your A/R aging periodically, draw against the available borrowing base, and repay as your customers pay you. Your collections process stays entirely in-house.
Confidentiality
No Notice of Assignment. No customer contact.
Unlike standard invoice factoring, AR funding does not require a Notice of Assignment to your customers. Sigma does not contact your customers. You maintain the full collection relationship — your customers simply pay you as normal, and you repay Sigma from your collections.
Structure
Revolving line — draw and repay at will
AR funding is a revolving facility, not a per-invoice advance. You submit your A/R aging on a scheduled basis, Sigma calculates your available borrowing base, and you draw up to that amount. As customers pay, your outstanding balance reduces and new availability opens up.
Risk
Non-recourse options on eligible receivables
Sigma can structure non-recourse protection on specific receivables within an AR funding facility — meaning if an eligible customer becomes insolvent and can't pay, Sigma absorbs the loss on that receivable. Your exposure is limited even without customer notification.
Balance Sheet
Off-balance-sheet or on — your choice
Depending on how the AR funding facility is structured — as a true sale or as a secured borrowing — it may or may not appear on your balance sheet as debt. We structure the facility to match your accounting and reporting requirements. Your CFO and auditors are consulted before closing.

AR Funding Is Right For You If
You Need Capital Without Disclosure
Your customer relationships require confidentiality
Enterprise or government customers that would react negatively to a Notice of Assignment. Professional services clients with long-standing relationships. Industries where NOA carries stigma.
You want to retain control of collections
You have a dedicated A/R team, an established collections process, and a track record of getting customers to pay on time. You don't want or need Sigma managing that relationship.
You need a revolving facility, not invoice-by-invoice funding
Your cash flow needs are ongoing and variable — not tied to specific invoices. A revolving line lets you draw what you need, when you need it, up to your borrowing base.
Your bank line doesn't cover your A/R cycle
AR funding can supplement an existing bank line or replace it entirely. It advances specifically against your receivables — giving you higher availability against the asset that actually drives your cash flow.
How do I draw against the facility?
You submit an A/R aging report to Sigma on a scheduled basis — typically weekly or monthly. We calculate your eligible receivables and your available borrowing base. You draw against that base via wire request. As you collect from your customers and repay the outstanding balance, new availability opens up.
What makes a receivable "eligible"?
Eligible receivables are generally: invoiced to creditworthy B2B customers, not past due beyond a defined threshold (typically 90 days), not in dispute, not concentrated beyond agreed limits, and not cross-aged by a customer with a significant past-due balance. The specific eligibility criteria are defined in your credit agreement and negotiated based on your portfolio characteristics.
How does Sigma protect itself if customers don't pay?
Sigma holds a UCC-1 lien on your accounts receivable as the primary security interest. Because you manage collections, we monitor your aging report closely — ineligible or aging receivables reduce your available borrowing base, which naturally limits exposure. Non-recourse provisions can also be included for specific customers or receivable types.
Is this the same as a bank revolver secured by A/R?
Structurally similar, but different in key ways. A bank A/R revolver typically requires strong business credit, financial covenants, a long approval process, and annual renewals. Sigma’s AR funding is underwritten primarily against your receivables quality — not your balance sheet — and can be structured and deployed faster. We also offer non-recourse options that banks rarely do.
Is there a personal guarantee requirement?
AR funding facilities are underwritten against the quality of your receivables, not your personal assets. Personal guarantees are typically not required. We evaluate each facility on its own terms — the specifics depend on your receivables portfolio and the structure we agree on.
