What our customers have to say
Ten Tigers has been my grain marketing advisor now for a period of 17 years. I have entrusted Chris Tonkin and his team to assist and direct me in the selling of my grains to suit my needs. With their experience, knowledge and regular contact and updates, I have been able to concentrate on the physical and practical side of farming without the added stress of watching the markets and possibly making wrong decisions. Allowing Ten Tigers to be my “personal broker” has put me in a position where I can relax, travel and profit from my every day farming life.
In the seventeen years we have been working with Chris and his team there has been a huge transformation in grain marketing in our business. Ten Tigers has made these steps a comfortable journey instead of the hill climb they appear to be when we receive correspondence from all different grain identities and our legal obligations we need to meet. Ten Tigers has assisted us to achieve higher daily prices regularly with good communication and sound advice. Ten Tigers has been an important member of our business allowing us to concentrate on growing our grain with the knowledge that Ten Tigers is there to worry about the marketing, optimisation and filling of contracts. The very detailed information that is supplied to us makes record keeping and entering  details into our accounting program very simple and quick.
Ten Tigers has helped our grain operation grow through a well-balanced marketing program of all our grain types in the current season and beyond. Ten Tigers has given me a greater understanding of our grain business through a fully transparent summary at the completion of each marketing season. Ten Tigers has given our business confidence to expand grain production by allocating achievable pricing target levels on all our grain types. Our business can better allocate time towards the production side knowing that Ten Tigers is managing our marketing in a professional, unemotional manner.
We decided to engage the services of Ten Tigers because we found we were becoming increasingly overwhelmed by the grain marketing decisions we had to make. We were sometimes making poor decisions because we had become indecisive and didn’t have clear target prices in place. We have found the staff at Ten Tigers an absolute pleasure to deal with. They are proactive in keeping lines of communication open and the paperwork they provide us with is easy to understand and very useful. The advice Ten Tigers has provided exactly what we needed. They have helped us set and reach targets and we have already seen the benefits of the grain marketing strategies they helped us put in place.
Ten Tigers is a business that specialises in grain marketing and consulting. We use Ten Tigers to help us achieve the best price for our grain, to find out what is happening in the world’s grain market to date and to help with marketing strategies. The best thing is, all this can be achieved by just a few text messages per day and / or a quick phone call while I stay busy growing as much grain as I can. I find them a great deal of benefit to our grain farming business.
