iwoca Explained

Market Invoice is an independent UK invoice finance comparison site. We do not broker or sell iwoca. This page is here to explain what it is and how it differs from invoice finance.

iwoca is a major UK fintech SME lender, but its core product is a flexible revolving credit line (the Flexi-Loan), not invoice finance. It lends against the business, not the sales ledger, with same-day decisions, no debtor notification, and interest charged only on the drawn balance. Businesses often compare iwoca with invoice finance because both solve short-term cash flow, but they work differently: one funds the ledger, the other gives you a general credit line.

Summary

iwoca is not invoice finance. It provides a revolving business credit line with same-day decisions, no debtor notification, and interest only on the drawn balance. It fits businesses with few or large single debtors and fast one-off cash flow gaps, but monthly interest can exceed invoice finance for sustained borrowing and the limit is generally lower than a whole-ledger IF facility. Market Invoice does not broker or sell it; this is comparison and education only.

What iwoca actually is

iwoca is one of the larger UK fintech lenders to SMEs, founded in 2011. Its core product, the Flexi-Loan, is a revolving credit line: you are approved for a limit, draw down what you need, and pay interest only on the drawn balance, repaying and redrawing flexibly. Decisions are typically same-day, with no fixed minimum turnover. Crucially, iwoca lends against the business as a whole, not against your invoices, so there is no factoring of your ledger and no contact with your customers.

That makes it a working-capital line, not an invoice finance facility. It is a perfectly good cash flow tool, but it is a different tool from advancing cash against unpaid invoices, which is why we explain it here rather than rank it as an invoice finance provider.

How it differs from invoice finance

Invoice finance and a Flexi-Loan both ease short-term cash flow, but they are built differently. Invoice finance is tied to your sales ledger: the lender advances typically up to 90% of an invoice within a day or two, and the facility grows as your invoicing grows. iwoca's credit line is tied to the business: it is not linked to specific invoices, it scales with your overall risk profile rather than your ledger, and it is drawn and repaid at will.

Our position

iwoca is a strong, fast and transparent fintech lender, but its product is a revolving business credit line, not invoice finance. Market Invoice does not broker, sell or earn commission on iwoca. We include this page so businesses comparing options can tell the two apart: if you want a flexible credit line against the business, iwoca is one of the better-known choices; if you want cash advanced against your unpaid invoices, that is invoice finance, and that is what we help you compare.

iwoca and Invoice Finance FAQ

Is iwoca an invoice finance lender?

No. iwoca is a major UK fintech SME lender, but its core product is a flexible revolving credit line (the Flexi-Loan), not invoice finance. It lends against the business rather than advancing cash against specific invoices in your sales ledger. True invoice finance lenders such as <a href="/providers/aldermore/">Aldermore</a>, <a href="/providers/bibby/">Bibby Financial Services</a> and <a href="/providers/close-brothers/">Close Brothers</a> advance a percentage of your unpaid invoices; iwoca gives you a credit line you draw down as needed.

What is the difference between iwoca and invoice finance?

Invoice finance advances cash against your unpaid invoices: the lender funds typically up to 90% of an invoice's value within a day or two, and the facility scales with your sales ledger. iwoca instead gives you a revolving credit line drawn against the business as a whole, with same-day decisions, interest only on what you use, and no link to specific invoices or debtor notification. One is tied to your ledger; the other is a general working-capital line.

Why do businesses compare iwoca with invoice finance?

Both solve short-term cash flow, so they are often weighed against each other. iwoca can be a better fit when you have few invoices or one or two large debtors, where whole-ledger factoring is awkward, or when you want fast, flexible cash with no customer contact. Invoice finance tends to win when you have a high-volume sales ledger, because the facility grows with your invoicing and can work out cheaper for sustained borrowing.

Does iwoca notify my customers or factor my ledger?

No. Because iwoca lends against the business rather than your invoices, there is no factoring of the ledger and no notification to your customers. You draw and repay flexibly and pay interest only on the drawn balance. That confidentiality and simplicity is part of the appeal, but it also means the facility size is generally capped lower than a whole-ledger invoice finance limit.

Does Market Invoice broker or sell iwoca?

No. Market Invoice is an independent UK invoice finance comparison site. We do not broker, sell or earn commission on iwoca. This page is educational: it explains what iwoca is so you can tell the difference between a revolving business credit line and funding advanced against your sales ledger. If your need is cash against unpaid invoices, we can match you to UK invoice finance providers.

When should I choose iwoca over invoice finance?

Lean towards iwoca when you have few invoices or large single debtors, want a fast one-off cash flow fix, or want no debtor contact at all. Lean towards invoice finance when you have a high-volume ledger that suits factoring or discounting, or want the lowest-cost long-term funding that scales with your sales. iwoca's monthly interest can exceed invoice finance for sustained borrowing, so the right choice depends on how you borrow.
