Key Facts
When Optimum Finance Fits
-
Mid-market businesses with £500k to £5m turnover wanting independent flexibility
Optimum's £50k minimum suits SMEs outgrowing selective discounting but not yet ready for bank-tier underwriting. The eCapital backing means they can fund growth above £1m without facility caps you would hit at smaller independents.
-
Recruitment, manufacturing, or distribution with sector-specific debtor concentrations
As an independent, Optimum underwrites case-by-case rather than using rigid sector scoring. Recruitment agencies invoicing a handful of corporate end-clients, and manufacturers with 30 to 40 percent debtor concentration on one buyer, both fit their flexibility.
-
Businesses wanting personal service plus group-tier financial strength
Smaller independents can struggle when client cash flow needs jump unexpectedly. eCapital's wider treasury means Optimum can flex facility limits without the multi-week credit committee cycle banks need.
When to Look Elsewhere
-
Startups or under 12 months trading
Better fit: Hydr or Triver. Optimum, like most independents, prefer trading history; Hydr and Triver focus on early-stage and spot factoring without minimum trading time.
-
Larger facilities above £2m looking for the lowest possible rate
Better fit: Close Brothers or Skipton Business Finance. Bank and building-society backing translates to lower cost of funds; service charges from 0.5 percent are common above £1m turnover.
How Optimum Compares
| Provider | Min facility | Fee from | Speed |
|---|---|---|---|
| Optimum Finance | £50k | 0.75% | 5 days |
| Ultimate Finance | £50k | 0.8% | 3 days |
| IGF Invoice Finance | £50k | 1.0% | 5 days |
vs Ultimate Finance: Ultimate is faster to set up (3 days vs 5) and has a marginally higher fee. Both sit in the same independent tier; choice usually comes down to which underwriter responds faster to your specific sector.
vs IGF Invoice Finance: IGF (part of Investec) targets turnaround and complex files at higher rates. Optimum is cleaner-file friendly with simpler pricing.
Worked Example
A Manchester recruitment agency with £900k turnover invoicing four corporate clients on 45 to 60 day terms.
Our Verdict
Optimum Finance offers a useful combination of independent flexibility with the financial backing of eCapital. The £50k entry point is accessible, and the group backing means they can support growth better than many smaller independents. A good middle ground between a pure independent and a bank-backed provider.
