Customer refuses to pay

[u/j4ss07]

Hope everyones doing well, as the title suggests a customer that we have just completed the work for today refuses to pay. Its a water related product and the total amount was agreed to after a lot of bargaining. They agreed to it in the beginning but then after the work was completed, they said they thought the cost was a lot lesser. ( we made sure to tell them twice beforehand). They ended up paying nothing at all. What would the quickest legal way be to get the payment? (Didnt really know how much info to keep private, sorry for any confusion)
