First, send a polite reminder email to your client asking for payment. If that doesn't work, follow up with a phone call or in-person meeting to discuss the issue. If the client still doesn't pay, consider sending a demand letter from a lawyer or using a debt collection agency. It's important to keep records of all communication and invoices related to the unpaid work.
Yes, you can charge interest on overdue payments. However, you should include this in your contract or agreement with the client beforehand. The interest rate should be reasonable and in line with industry standards. You should also clearly communicate the interest charges to the client and include them in any invoices or payment reminders.
One way to prevent overdue payments is to have a clear payment policy in place and communicate it to your clients. This should include payment terms, due dates, and consequences for late payments. You can also consider using online payment platforms that automate the payment process and send reminders to clients. Another option is to require a deposit or partial payment upfront before starting work.
If a client refuses to pay you, you may have legal options such as filing a lawsuit or using a debt collection agency. However, it's important to consult with a lawyer to understand your rights and options. Keep in mind that legal action can be time-consuming and expensive, so it's often best to try to resolve the issue through communication and negotiation first.
