Collect supporting files during signing: SignRequest and a PDF-only workflow
A signature box and a supporting-file upload are different requirements. List the files you need from the recipient before choosing a signing service, including whether the request should be blocked until those files arrive.

DocAISign paid checkout is not currently enabled. Self-signing is free; check your available sends and the Pricing page before planning a request.
SignRequest describes recipient attachments
SignRequest’s feature page says senders and recipients can attach documents and that signer attachments can be required. That is a specific collection capability, not merely the ability to email a PDF after signing.
Check the current tier and usage rules
SignRequest’s plans page lists sender/signer attachments alongside other plan features. It also describes fair-use conditions and extra fees for some capabilities. Verify the actual tier and collection limits rather than assuming every feature is included in an unlimited-document headline.
Define what the recipient must provide
- Which supporting files are required, and why?
- Which formats and sizes will be accepted?
- Must upload happen before the recipient can finish?
- Who can access the files after collection?
- How will the completed document and attachments be exported and retained?
Test the missing-file case
Use fictional files and a controlled recipient. Try completing the request without the required attachment, then with an accepted sample. Inspect the exported result: a successful signature does not prove that every supporting file is available to the staff who need it.
Do not collect identity documents or other sensitive material merely because an upload control exists. Establish the required purpose, access and retention through your organisation’s normal process.
DocAISign does not collect recipient uploads
DocAISign currently provides signature/date fields for you and one other recipient. It has no supporting-file upload field for the signer. The signed PDF and audit delivered after completion are outputs, not a mechanism for collecting recipient attachments.
If you already use an approved separate collection channel, keep the references aligned yourself. If required uploads must be part of completion, evaluate a workflow that explicitly supports them. Do not try to turn one private invitation into a public file-drop link.
Keep the complete record together
Decide how you will match supporting files to the correct signed version. Keep the completed PDF, available audit and supporting material in their intended controlled locations. Closing a signing link does not recall files that have already been downloaded.
