I have been using commusoft for at least 3-4 years now and honestly could not run my business without it. The main reason in my decision was to keep up to date with invoicing and cash flow. When working flat out, I cannot keep up with who owes me, what jobs are not complete, which customers need quotes. I am still far from perfect but I am so much better off. No paper gas certs, invoices or quotes to keep storage for. In short, the idea of running my business with a paper diary and writing out paper invoices would lead to more stress than it is worth. I could never do business without joining the 21st century.
