Late Payment Demand Letter for Glass & Aluminium Contractors

What a good one includes

• An exact reference to the original contract or quote, including the dates the glass or aluminium work was ordered and completed.
• An itemized breakdown of the outstanding invoice numbers, original due dates, and any accrued late payment interest as permitted by your terms.
• A clear, specific description of the completed glazing or fabrication installation to prove the work was delivered as agreed.
• A firm, non-negotiable deadline for payment, typically seven to fourteen business days from the date of the letter.
• Your current bank account details and accepted payment methods to leave the client with no excuses for further delays.
• A professional warning outlining the next steps, such as initiating debt collection agency action, legal proceedings, or registering a construction lien.

Common mistakes to avoid

• Using emotional or aggressive language that lowers your professionalism and makes a mediator or court less sympathetic to your case.
• Failing to attach copies of the original unpaid invoices and signed delivery dockets, which gives the client a reason to delay payment further.
• Giving vague payment deadlines like as soon as possible instead of specifying a hard, unambiguous calendar date.
• Forgetting to send the letter via a trackable delivery method like registered post, leaving you with no proof that the client actually received it.
