Sub & Vendor Portal: Invite Subs, Collect Bids, and Coordinate Projects

The Sub & Vendor Portal gives you one place to invite your subcontractors and vendors, share project files, collect bids, coordinate schedules, and track invoices, without adding paid seats for each sub.

Written by Handoff Support

📌 The Sub & Vendor Portal is available on the Scale plan only.

Setting Up Your Portal

  1. Open a project and navigate to Sub & Vendor Portal

  2. Prepare the portal: add documents, drawings, bid requests, or any files you want to share

  3. Invite subs or vendors by email or SMS

  4. They open the invite, choose to receive a 6-digit code by email or text, enter it, and see exactly what you've shared

How Your Subs Sign In

  1. Your sub opens the invite you sent by email or text.

  2. They choose where to receive their code. They'll see the email and/or phone number you have on file for them.

  3. Handoff sends a 6-digit code. It's valid for 15 minutes, and they can tap Resend if it expires.

  4. They enter the code and land in the portal.

Invite links don't expire, and once signed in, subs stay signed in on that device. Subs who go to the portal without an invite link can sign in by entering their phone number or email address and requesting a code.

If a sub can't sign in:

  • The code didn't arrive: Have them tap Resend, or go back and choose their other contact method. If they only have one, check that their email or phone number is correct on their contact.

  • "We couldn't tell which contact this is": The same email or phone number is on more than one of your contacts. Give each contact their own, or ask the sub to sign in from their invite link.

What You Can Do

Invite Subs & Vendors

Invite subs or vendors by email or SMS. When they open the invite, they choose where to receive a 6-digit sign-in code, enter it, and they're in. No account, password, or paid seat required.

Bid Management

  • Generate a scoped bid request directly from your estimate

  • Send it to one or more subs

  • Collect structured responses and compare them side-by-side

  • Get an AI recommendation, award the winner, and push the rates back to your estimate

Document Sharing

Share drawings, specs, schedules, or any project files with your subs or vendors. Files are securely accessible via the portal and can be downloaded by guests.

Daily Logs

Subs can post job site updates directly from their portal. All entries appear in your existing project log.

Invoices

Subs can upload invoice files to the portal. You kick off the budget import in one click from your end.

Time Tracking (optional)

Enable time tracking for your subs so they can clock in and out of jobs directly from the portal.

How Bids Work

  1. Open the portal → go to Bids

  2. Select estimate line items to generate a scoped bid request (AI drafts the scope based on your estimate)

  3. Review and send to your subs or vendors

  1. Subs submit their response through the portal

  2. You compare responses side-by-side, get an AI recommendation, and award the work

  3. The winning rates are applied back to your estimate

Frequently Asked Questions

  • Do my subs need to create a Handoff account?

    • No. They open their invite and enter a 6-digit code we send to their email or phone. No account or password needed.

  • Does adding subs cost extra?

    • No. The Sub & Vendor Portal is included in the Scale plan, and subs don't take a paid seat.

  • Can I control what my subs or vendors see?

    • Yes. You choose which documents, bids, schedules, and files to share with each sub or vendor.

  • Can vendors message me through the portal?

    • Yes. There is in-portal messaging, either a general thread or per-object (per document, per bid, etc.).
