The comparison site that shows its workings.
Tell it what your business spends and how you pay. It ranks every product in pounds, from figures read off the providers' own pages, and shows the sum for each one.
Or compare fuel cards, expense tools and business savings.
What it does, with a real sum
Take a company turning over £300,000, putting £6,000 a month on a card and paying it off in full, with 5% of their spend in a foreign currency. Today the calculator ranks its first year like this:
| 1 | Funding Circle Cashback Card2% intro cashback, no fee | £1,080 |
| 2 | BA Amex Accelerating BusinessAvios for flyers | £826 |
| 3 | Capital on Tap Free RewardsNo-fee all-rounder, 0% FX, free Avios conversion | £720 |
Change one answer, say the company carries a balance, and the order changes, because interest becomes the largest number in the sum. Every card's workings are on the page, for you to compare.
