How to bid with Bid Now

How Bid Now works

The vendor journey is the same shape no matter which method a solicitation uses.

1. Register and build your profile once — your business details, contacts, and classifications.
2. Keep your compliance documents current (insurance, bonding, licenses) so you're eligible when it counts.
3. Get matched to opportunities by your NAICS and commodity codes, and receive notices.
4. Respond — submit a sealed bid, join a live auction, or send a proposal, depending on the solicitation.
5. Follow through — acknowledge any changes (addenda), and watch for the award decision.

1Create your vendor account

Registration establishes who you are and lets the agency reach you.

1. From the agency's Bid Now portal, choose Register as a Vendor.
2. Enter your business's legal name, mailing address, and primary contact (name, email, phone). Use an email you check often — it's where notices and bid receipts go.
3. If your organization has a UEI (Unique Entity ID from SAM.gov), enter it. It's used later to confirm you're eligible for award, so it's worth adding now.
4. Set a strong password and complete any verification step, then sign in.
5. Open your Vendor Dashboard — this is your home base for opportunities, submissions, documents, and messages.

2Classify your business & get matched

Classification is how the system knows which opportunities to send you.

1. In your profile, open Classifications.
2. Add the NAICS codes that describe what you sell or do. Add every code that genuinely applies — each one widens the opportunities you'll be matched to.
3. If the agency uses commodity codes (for example NIGP), select the categories that fit your goods and services.
4. Save. From now on, new opportunities in your categories can trigger a notice to you.

3Keep your compliance documents current

Insurance, bonding, and licensing are checked before an award — expired paperwork can cost you a contract you won on price.

1. Open Compliance (or My Documents) in your dashboard.
2. Upload each required document — commonly a Certificate of Insurance (COI), a bond, and any applicable business or trade license. Enter the expiration date for each.
3. Submit. Your upload is marked pending verification and the agency's staff are notified to review it.
4. Watch your dashboard and email. Staff will mark each document verified, or ask you to resubmit if something's missing or unreadable.
5. Renew before documents expire. The system tracks expiration dates and the agency may block or flag an award if a required document has lapsed.

4Find & follow opportunities

Opportunities reach you two ways: notices pushed to you, and the open list you can browse anytime.

1. Check your email notices — matched opportunities in your categories are sent to your registered address.
2. Browse the open opportunities list in the portal. Each entry shows the type (sealed bid, reverse auction, proposal), the closing date/time, and the buying office.
3. Open one to read the details, documents, and schedule.
4. If you intend to respond, follow it so it appears on your dashboard and you get any updates.

5Read a solicitation & ask questions

Read everything, and use the Q&A — questions and their answers are shared fairly with all bidders.

1. Open the solicitation and read the scope, specifications, terms, and every attached document.
2. Note the question deadline — it's usually earlier than the bid deadline.
3. Submit questions through the solicitation's Q&A. Ask clearly; you don't need to reveal your pricing or approach.
4. Watch for answers. To keep the process fair, answers are typically published to all bidders (often without naming who asked).

6Addenda — acknowledging changes

An addendum is an official change to the solicitation. You must acknowledge each one, and a new addendum can require you to re-affirm a bid you've already placed.

1. When an addendum is issued, you'll be notified and it will appear on the solicitation.
2. Open and read it — it may change scope, quantities, dates, or terms.
3. Acknowledge it. You generally cannot submit (or your existing submission won't count) until every addendum is acknowledged.
4. If you had already submitted, a new addendum will flag your submission for re-affirmation — confirm your bid still stands under the changed terms, in one click.

7Submit a sealed electronic bid

A sealed bid stays locked and invisible to everyone — including agency staff — until a scheduled public opening.

1. Open the sealed solicitation and choose Submit a bid.
2. Enter your pricing and complete every required field and attachment.
3. Acknowledge any addenda (section 6) and sign if a signature is required (section 12).
4. Submit before the deadline. Your bid drops into a sealed lockbox and you receive a timestamped receipt — keep it.
5. Need to change it? As long as the deadline hasn't passed, you can usually withdraw and resubmit. After the deadline, submissions are final.
6. At the scheduled opening, all bids are unsealed together and tabulated. You can see where you stood once results are posted.

8Participate in a live reverse auction

In a reverse auction, price competition happens live: you bid the price down in real time, and the lowest wins.

1. Make sure you're eligible before the event — profile complete, any required credentials in place.
2. At the start time, open the live auction screen for the solicitation.
3. You'll see your rank (for example "Rank 2") — not competitors' identities or exact prices.
4. Place a lower bid to improve your position. You can bid as often as you like before the clock ends.
5. Watch the countdown. If a bid lands in the final moments, anti-snipe extends the clock so everyone has a fair chance to respond.
6. When the clock closes with no further bids, the auction ends and the standing is final.

9Multi-line reverse auctions

A multi-line auction puts many line items out at once. You can lead on some lines and not others.

1. Open the auction and review the schedule of line items (each item, unit, and quantity).
2. Bid on the lines you want. You don't have to bid every line — bid where you're competitive.
3. Track your rank per line. Improve individual lines as the event runs.
4. Depending on the solicitation, the agency may award line by line to the lowest on each, or in aggregate to the lowest overall — read the terms so you know which.

10Technical proposals (RFP / best value)

Some solicitations are decided on merit, not just price. You submit a technical proposal that a panel scores against published criteria.

1. Read the evaluation criteria and weights in the solicitation — they tell you exactly what the panel rewards.
2. Prepare your technical proposal: approach, relevant experience, key personnel, schedule — whatever the criteria call for.
3. If it's a two-envelope RFP, submit your price separately from the technical proposal. Price is opened only after technical scoring, so keep it out of the technical documents.
4. Submit before the deadline and keep your receipt.
5. A panel scores each proposal independently; scores are combined (and blended with price if the RFP says so) into a best-value ranking.

11Two-step reverse auctions

A two-step auction combines the last two methods: first you qualify on the work, then you compete on price.

1. Step 1 — technical, unpriced. Submit a technical proposal with no price. It stays sealed until the Step-1 deadline.
2. Staff review each proposal and mark it acceptable or not (pass/fail, or scored against a threshold). You'll be notified of the determination.
3. If asked, you may be given a chance to submit a revised technical proposal before the gate closes.
4. Step 2 — live price. If you qualified, you're admitted to the live reverse auction and bid the price down (section 8). If you didn't qualify, you'll see the reason and won't be able to bid.

12Digital signatures

Some submissions require a signature to be binding.

1. When a signature is required, you'll be prompted during submission.
2. Review exactly what you're signing — the bid, a certification, or an acknowledgment.
3. Sign as instructed. The signature is recorded with a timestamp as part of your submission's record.

13After the bid — awards, debriefs & protests

Once responses close, the agency evaluates, screens the apparent winner, and records an award.

1. Before award, the agency confirms the apparent winner is not excluded/debarred (via SAM.gov) and that required compliance documents are current.
2. You'll be notified of the outcome. Results and a tabulation are typically posted.
3. If you weren't selected, you may be able to request a debrief to understand the decision — check the solicitation or ask staff.
4. If the solicitation has a protest window and you believe there was an error, you can file a protest through the portal within the stated period; staff review and respond on the record.

14Managing your account & getting help

1. Keep your contacts, classifications, and documents current — most problems trace back to stale profile data.
2. Use your dashboard's messages/notices to stay on top of questions, addenda, and results.
3. Forgot your password? Use the reset link on the sign-in screen.
4. Stuck on a specific solicitation? Use its Q&A for anything about that opportunity.
