I have used Courier Expert since 16/4/2015 off & on. What does that mean? Well, most of my earnings are EU-based. However, when I am back in the UK I look at the CE app to find work that I think is viable to myself, either for a car, or a van. In my case, my car is one of the smallest in the world but I can make the site work for me; it helps significantly if you enjoy driving. My maximum per-mile cost (CAR) is £0.18ppmt (pence per mile traveled). I choose to have a margin of 66% on each job, thus if I can't make at least that margin, I won't offer my services. Yes, I can stack shelves in Tescos overnight to earn a higher wage but poo to that idea! I've verified earnings to date of just short of £30k. Yes, it's a poor average but, it's not my only income - You won't earn a living off these types of sites! All sites are BACK-LOAD geared or you need to pay fees to accept work; it's simply a case of being picky with what work one bids on or accepts for yourself. So, where you are located can be crucial to daily viability. How much time will it take, at what costs to you determines your margin and if viable. It is actually a very simple system of supply & demand. Please don't blame the site if you personally can't make it work. I am located in the West Country; not the best location for higher work volumes like LONDON. The positives for joining CE are the simplicity of the app, GOB, POD & INVOICING, all on one app with prompt payment. Car jobs are often a doddle, envelope to car part. Van jobs just have more weight and volume. My car/van tax, insurance, servicing MOT when required oh, and the occasional KFC are subsidised by my earnings from this company. They are professional, helpful and very accommodating. I've no compunction in giving ***** STARS.
