We did a landscape job for a lawyer downtown and hes unhappy about it. We installed sod, landscape ties, 5.5 yards of mulch, 4 yards of prosoil and edging. On top of that we removed the old sod and tilled the new soil with the old soil and picked everything up. He's unhappy because we could plant the three bushes he wanted because there was too much broken concrete mixed with the soil at the only spot he wanted them and it would take us over budget to plant them. Now hes calling me because he wants to compromise on the bill?? We charged $450 for labor and I think we way underbid it. Any ideas on what i should do?
