One option that we use a lot is that we do the mulching early in the spring and add it into there monthly maintenance contract price. Example : a client is charge $200.00 for 8 months of maintenance. Lets say you installed 10 yards of mulch in april. 10 yards = $550.00. Break down that $550.00 over the 8 months = like $68.00. So instead now you charge like $268.00 a month for maintenance. The only negatives are that you are going to have to front the money for the mulch and labor. But, you will get it all back in the long run, and will increase your mulch sales. Some clients get scared when they see a mulch estimate for $550.00, but seeing an extra $68.00 a month, doesnt scare so many away.
