What are people saying about us?

Insolvency practioners love us. So will you.

Wilson Field
Kat Richardson-Green, Head Of Strategy & Business Analyst

"Staff productivity is game changing! Insolvency procedures can be rather paper demanding but it doesn’t need to be. We have proof of postage, a 75% reduction in post going out the door and a 37% reduction in print costs."

Alvarez & Marsal
Greg Clough - Associate Director, Alvarez & Marsal

"The actual process of uploading and sending the letters took about four minutes. The first creditor made contact at 10:55 the next morning. The system is scalable so where our next job has 20,000 creditors we don’t need to outsource to a specialist printer, courier documents or approve proofs. The whole process is intuitive, beyond simple, swift, and costs less than the stamp. There is nothing not to like.”

Communications Director

"Everything is just easy, unlike with other suppliers. You take away even the smallest tasks and just provide to us what we need as a business. There’s no language that’s too technical and you don’t bombard us with info."
