A client won't pay. A step-by-step for Arizona contractors.
The practical order of operations when a client stops paying: documentation, the payment request, the preliminary notice question, and what each escalation path really costs.

You finished the work. The invoice is sitting there. The client has gone quiet, or worse, has started inventing complaints. Here is the order of operations Arizona contractors actually use, and what each step costs.
Step 1: Freeze the record before you do anything else
Every path below runs on documentation. Before you send another text, gather: the signed scope or contract, every change order and who approved it, your invoices, proof of every payment received, the texts and emails about the work, photos of the completed job, and your daily logs. Put dates on everything. The single most common reason contractors lose payment disputes is not that they are wrong. It is that their records are scattered across a truck, a phone, and a shoebox.
Step 2: Send a written payment request, on the record
Not a text. A dated, written request that states the contract amount, approved change orders, payments received, the balance due, and a clear deadline. Send it in a way you can prove: email plus certified mail is the classic combination. A calm, factual letter gets paid more often than an angry one, because it signals you have your paperwork together and are prepared to escalate.
Step 3: Know your lien position, and its deadlines
Arizona ties most lien rights to the 20-day preliminary notice (A.R.S. 33-992.01), and on owner-occupied homes only a party with a written contract directly with the owner-occupant can lien at all (A.R.S. 33-1002). Lien deadlines are short and unforgiving. Whether a lien is available and wise in your situation is a question for an Arizona construction attorney, but knowing whether you served a preliminary notice, and when the clock started, changes every conversation that follows.
Step 4: Price the escalation paths honestly
- Doing nothing: costs you the full balance, and teaches the client's friends that you are free.
- A lawyer-drafted demand letter: commonly a few hundred dollars, around $500 on average nationally.
- A collections agency: typically 30 to 50 percent of whatever they recover on small or aged consumer debts.
- Small claims court in Arizona: handles claims up to $3,500 in justice court small claims; filing is cheap, but your evidence does the work.
- A civil suit: real money and real time, and only worth it with a clean record.
Notice the pattern: every path gets cheaper and stronger when your documentation is already organized, and every path gets weaker the longer you wait.
Step 5: Match the tool to the balance
Under about $3,500, small claims plus a strong written record is often the whole game. In the $3,500 to $30,000 band, the demand letter, lien position, and attorney review matter most. Above that, involve a construction attorney early. In every band, the first move is the same: organize the record, then ask for the money in writing.
The unlicensed trap
One hard Arizona rule to know: an unlicensed contractor generally cannot sue to collect for work that required a license (A.R.S. 32-1153). If you are working around the licensing line, your collection options may be close to zero. Keep the license current; it is literally what makes your invoices collectible.
