Drawing up a compliant invoice
Two overlapping texts, a number sequence whose gap costs more than the fine, a down payment invoiced before delivery, and late-payment penalties that run with no formal notice. Three modules on a graphic designer, a 3 400 € invoice and a 12 000 € unpaid bill. All the prose is free to read; only the quizzes are sold.
