Up-sell and cross-sell to increase your average unit of sale.In general, when you increase the amount you sell to your customer at one time, you’ll improve your margins because you’ll be increasing the purchase velocity and therefore lowering your cost per sale in terms of overhead burden. So how can you increase your average unit of sale per customer? Can you up-sell to richer offerings? Can you offer larger units of purchase? Can you cross sell complementary products or services?
All of this allows you to amortize your marketing cost over a larger unit of sale which dilutes your marketing cost for each sale and hence grows your profit margin.
