    How to collect client documents securely

    A practical workflow for collecting IDs, contracts, invoices, reports, and other client documents without messy email attachments.

    7 min readUpdated May 2026

    Who this is for

    For legal teams, accountants, consultants, agencies, immigration services, and founders who collect sensitive documents from clients.

    Client documents deserve a calmer workflow

    Collecting client documents should not require five reminder emails and a folder permissions lesson. The client usually wants to do one thing: send the documents and move on.

    For the team receiving the files, the needs are different: clear ownership, fewer missing attachments, private delivery, and a reliable place to find the final files later.

    Why email is weak for document collection

    Email works for messages, but it becomes messy when documents start moving. Attachments get split across threads, file sizes hit limits, and sensitive PDFs can be forwarded long after the work is done.

    For lawyers, accountants, consultants, and client-service teams, the risk is not only technical. It is operational. You lose time checking what arrived, what is missing, and which version is final.

    Use one secure upload link

    A secure upload link gives the client a single destination. The request can explain exactly what is needed: ID scans, signed forms, bank exports, contracts, invoices, photos, reports, or project material.

    The client does not need a Sandra account. They open the page, upload the files, and the team receives them in one place.

    Add enough control without making it heavy

    For low-risk files, a private request link and expiry date may be enough. For sensitive documents, add password protection, stricter instructions, and a clear retention habit. Important final files can be saved in Vault so they are not lost after the request is complete.

    The best workflow is careful without feeling bureaucratic. Clients should feel protected, not trapped inside software.

    Client privacy includes AI boundaries

    More teams use AI every week, but client documents should not silently become training material. Contracts, IDs, financial exports, legal records, creative originals, and internal reports carry trust.

    Sandra keeps the boundary clear: customer transfers, file requests, and Vault files are not used to train AI models.

    Quick answers

    What is the safest way to collect client documents online?

    Use a private upload link with clear instructions, expiry controls, and a trusted place to store final files after collection.

    Is a client portal required?

    Not always. For simple document collection, a focused file request link can be easier than a full client portal.

    Can clients upload without signing in?

    Yes. Sandra file requests let clients upload from the browser without creating a Sandra account.

    Does Sandra use client documents for AI training?

    No. Sandra does not use client documents, transfers, uploads, or Vault files to train AI models.
