Unpaid invoices for small music businesses

Has anyone here dealt with a business customer who stopped paying an invoice for a music-related service? I'm curious how other small businesses handle this without immediately turning the situation into a legal battle. For example, a band, recording studio, equipment supplier, or event company might have a commercial client that keeps delaying payment. At what point would you consider getting professional help, such as a Houston commercial debt collection agency, rather than continuing to send reminders yourself? I'd be interested to hear what approaches have worked for others.

Unpaid invoice for small musics business are the record for selling the equipments or music voice notes in proper form.
