60 days overdue… send an ultra professional letter to the client’s top person (president, CEO, etc…) via certified mail and specifically ask them to respond in writing via certified mail explaining the reason that they refuse to submit payment.
If they respond properly, evaluate their reasoning and decide your next step.
If they do not respond:
90 days overdue, go to the post office and confirm that the letter was received and signed for by the person you addressed it to. If it was signed by someone it was not addressed to, call the company and specifically ask for the person who signed for it, and ask them if they gave it to the addressee. They will of course say yes. Ask them to transfer you to the addressee. When they tell you that the person is out of the office, immediately go there (if they’re local) and request to speak with the addressee and take a copy of the certified letter in a sealed envelope with a additional cover letter explaining that this is a copy of the same letter that was sent to them via certified mail and signed for by who.
Should they really not be there, leave the letter (politely) with the receptionist.
Call the person who signed each day, and politely ask them to transfer you to the addressee. Often receptionists do not sign for certified letter, a manager does, so they have more clout.
At 100 days overdue, make a slightly revised letter noting the attempts that you have made to contact the addressee and that this is a notarized version of the same letter. Go and have two copies of this letter notarized and have the Notary send the letter via certified mail (some will do this, some will not… find one who will). This notary service will cost some cash, but far less than an attorney.
At 110 days overdue, if you have not received a response, contact the notary and ask them to get the signing info on the certified mail they sent (again, probably a small fee)… use this and spend the next 10 days trying again to get through to the addressee via the signee.
If at 120 days you have failed to receive a response from the addressee, it’s time for the attorney (if the amount is worth it to you). You have a bit of a paper trail illustrating your attempts to collect in proper and polite channels so it’s an easier case, and the lawyer may give you a “prepared” client discount (don’t count on it tho).
If at any point the you do get the client on the phone or confront them in person, find out what’s going on and instill upon them that they need to send a response via certified mail in order to keep this friendly. Your client is delinquent, and unless the reason is damn good, you should expect them to respect you enough to put it in writing. If they don’t, well this is probably a bad client with a history of delinquency.
All of this is about treating each other politely and with respect, using the business tools put in place by society… you start out politely building a paper trail about the situation and build up to a more enforceable paper trail.
At lawyer time, the relationship is likely not salvageable, so don’t start there.
This is very effective if you keep your head, and your cool. Any smart business person knows where this is leading when they receive your first letter. They also know how they will look if they do not comply with your documented and perfectly responsible actions. By going straight to the top, you are probably going to piss off people in the middle, but you’ll get results and possibly a better relationship with the top, if you handle yourself well.
Your in business… that is the top game in the world. Play it like a pro.
