# Milestones FAQs **Our Applicants need to upload receipts/invoices, but these aren't required to trigger payments. How can I do this?** It's a great idea to use Milestones in this case, as it keeps all the required documentation assigned to the Application. You can use a Milestone template that has a "file upload" field, and set the Milestone payment amount to $0 so that it doesn't trigger a payment. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://help.tahua.io/knowledge-base/administrator-help-guides/milestones/milestones-faqs.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
