A business owner built small custom GPTs that turn a client name, service and amount into a finished quotation
The poster says they use custom GPTs as single-job tools, not chatbots: one makes quotations, and others make payment vouchers and work orders, each following rules they wrote. They worry the newer Skills and Plugins may drift off task, and want a chosen tool to always hand back the finished document instead of stopping partway or explaining the steps. They say this let them automate small repeated jobs without building software.
