Spot Factoring UK 2026: Selective Single-Invoice Finance

Spot factoring (also called selective invoice finance, single invoice finance, or pay-as-you-go factoring) lets UK businesses fund individual chosen invoices without committing the full sales ledger. You pay only on the invoices you fund. Fees vary by provider: Triver from 0.06% a day (about 1.8% on a 30-day invoice), Hydr a flat fee per invoice, Sonovate 2% to 4% blended for recruitment. Hydr, Triver and Sonovate all offer it.

Spot Factoring UK FAQ

What is spot factoring UK?

Spot factoring (also called selective invoice finance or single invoice finance) is per-invoice funding with no commitment to put further invoices through the facility. You pick which invoices to fund, the provider advances part or, at some providers, all of the invoice value (Hydr and Sonovate publish up to 100%), and the advance is repaid when your customer pays. You pay fees only on the invoices you fund, and there is no commitment to fund the rest of your ledger.

Which UK providers offer spot factoring?

Three examples, each with a different fit: Hydr (single invoices from any sector, a flat fee per invoice, no minimum turnover); Triver (connects to Xero, QuickBooks or Sage, fees from 0.06% a day, about 1.8% on a 30-day invoice, advances up to £100,000 per invoice); and Sonovate (recruitment agencies, 2% to 4% blended including back-office services). Figures are from each provider's profile page on Market Invoice, where the source is linked.

How much does spot factoring cost per invoice UK?

There is no single market rate: Triver charges from 0.06% a day (about 1.8% on a 30-day invoice), Hydr a flat fee per invoice, and Sonovate 2% to 4% blended for recruitment. The fee usually covers what a whole-book facility splits into a service charge and a discount charge.

Illustration: a £20,000 invoice funded at a 2.5% total fee costs £500. Pricing structures differ (Hydr charges a flat fee per invoice; Sonovate quotes 2% to 4% blended, including back-office services, for recruitment), so compare on total cost per invoice.

When should I use spot factoring instead of whole-book invoice finance?

Spot factoring suits irregular cash flow needs, growing businesses uncertain about long-term funding requirements, businesses with one or two large invoices to fund (rather than the whole ledger), seasonal businesses, project-based services, and businesses below the typical whole-book turnover threshold. Once you are regularly funding most of your invoices, get a whole-book quote as well and compare the total cost.

Can I switch from spot factoring to whole-book invoice finance?

Yes. Many UK businesses start on spot factoring to test the product, then upgrade to whole-book once their working capital need is sustained and predictable. Switching providers usually involves a parallel-running period.

Do I need a personal guarantee for UK spot factoring?

It depends on the provider and the size of the exposure, so ask before you apply. Because the funder is taking risk on a specific invoice rather than your whole business, some selective providers do not ask for one on single invoices; larger or repeated funding is more likely to need one.
