A note on Xero

Why we're moving away from Xero

Third-party software and platform costs keep rising, and they sit outside our control. That has meant price increases passed on to you. By moving to SleekBooks, we control our own costs, so we can keep your pricing stable as your business grows.

i

You can still stay with Xero, but Xero will be chargeable at £375/fy (excl. VAT) as an add-on cost to your Sleek service or paid for directly by you.

Your accountant, supercharged.

SleekBooks is included with your Sleek accounting service. No extra software, no extra cost.
