I run a small one person business and am completely lost when it comes to technology. Until recently I have been writing up my invoices in word, which has been inefficient and disorganised to say the least. A friend recommended Bullet HQ and it's been fantastic https://pocket-hose-silver-bullet.pissedconsumer.com/review.html . It's really easy to use, stores all of your information in one place, and looks great too. I know it has many more features than I am currently using (invoicing only) and I'm looking forward to making use of these too in the future
