The New-Vendor Onboarding Checklist: What to Do in the First 90 Days After You Sign a Partner Agreement

 Search for a partner onboarding checklist and almost every result is written for the vendor: how to onboard new partners into a channel program. This one is for the other side. You have just signed with a new vendor, and the clock has started on certifications, portal access, tier requirements, and agreement terms, whether or not anyone has written them down.

The first 90 days decide whether the relationship becomes a managed asset or a source of surprises in year two. Here is the checklist, in the order the work actually arrives.

Before you sign: ask the vendor these questions

• What exactly does each tier require, and how often is it assessed?
• Which requirements are tied to named individuals, and what happens when those individuals leave?
• How does the vendor communicate program changes, and with how much notice?
• What are the rules on deal registration, including how long it lasts and how conflicts are resolved?
• What funds or incentives are available, and what conditions apply?
• What does it take to exit, and what happens to customer subscriptions and licenses if we do?

Days 0 to 30: set up the record

1. File the agreement and record its key terms. Version, effective date, term, renewal, termination clauses, territory, exclusivity, discount structure, and any minimum commitments.
2. Name the relationship owner. One person accountable for the relationship, with a named backup.
3. Set up portal access properly. Create named accounts, enable multifactor authentication, and record who holds administrator rights. Agree now how access is removed when someone leaves.
4. Map the requirements. For the tier you are targeting, list every requirement: certifications, revenue, customer references, business plans, and anything else the program asks for.
5. Create the CRM fields. Add a field for the vendor’s opportunity or registration ID so deals can be tied to the vendor’s records from the first one.
6. Add the vendor to your portfolio view. Standing, requirements, owner, and next review date, in the same place as every other vendor.

Days 31 to 60: build capability

1. Decide who certifies first. Choose people deliberately, considering who else they hold credentials for, so you do not stack renewal risk on one engineer.
2. Schedule the training and put the cost in the budget. Include exam fees and the hours away from billable work.
3. Date every expiry. As each certification is earned, record its expiry date at once, not at renewal time.
4. Complete the partner profile and locator listing. These are often the first visible benefit and can drive inbound interest.
5. Find out what funds exist. Ask what marketing or development funds are available and what is needed to claim them. See our post on market development funds.

Days 61 to 90: make it operational

1. Register the first deal. Run one deal through the full process to find the friction early.
2. Schedule the first review. Put the first partner-side business review on the calendar, using the template in our QBR post.
3. Write the tier plan. A one-page plan stating the target tier, the certifications and revenue needed, the date, and the cost.
4. Set the change-watch routine. Subscribe a named person to program announcements and log each change with its effective date.
5. Run a 90-day check. Compare what the vendor promised before signing with what you have received.

The hidden cost of every new vendor

Each new vendor adds a portal, a set of logins, an agreement, a certification track, an assessment calendar, and a partner manager to keep in touch with. None of that cost appears on the signing page. Firms that add vendors without adding a way to manage them end up with the pattern described in our post on partner portal fatigue: more relationships than anyone can keep current.

A test before you add vendor number eleven: Can you list, from memory or from a single document, every status you hold with your existing vendors, who holds the certifications behind each, and when each is next assessed? If not, fix that before adding another.

What to do this week

• Pick the vendor you most recently signed and check how many of the Days 0 to 30 items are actually done.
• Copy the checklist into your project tool and assign owners.
• Add a standing item to your next leadership meeting: any new vendor agreements under consideration.

Who does what: a simple responsibility map

The checklist above lists tasks. These are the people who should own them, in a firm of typical size. Use titles that match your own organization.

Red flags in the first 90 days

• You cannot get a clear answer on what the next tier requires. If the vendor is vague now, expect surprise later.
• The partner manager is slow to respond. Responsiveness before the first deal is a preview of responsiveness after.
• Requirements reference documents that do not exist or are out of date. Keep the evidence and raise it.
• Portal access is shared. Shared logins are a security risk and a continuity risk. Fix them at the start.
• No one volunteers to own the relationship. An unowned vendor will cost money in some other way.

A 90-day review you can run

At day 90, hold a short meeting with the relationship owner and a sponsor. Ask four questions. Did the vendor deliver what it promised before signing? Are the costs we are carrying within what we planned? Do we have a path to the tier we want, and is it worth it? Would we sign again, knowing what we know? The answers decide whether the vendor becomes a managed asset or a candidate for the consolidation review.

Documents to collect and keep from day one

• The signed agreement and every amendment, with the effective dates.
• The tier requirements document, with the date you downloaded it.
• The program guide or benefits summary the vendor gave you.
• Contact details for your partner manager and an escalation contact.
• Portal account details, with named users and administrator rights.
• Any promises made before signing, in writing, such as funds, introductions, or support commitments.

The last item matters most. Verbal promises made during the sales process are the first thing to be forgotten when the relationship moves from courtship to operations. If it is important, ask for it in an email and file it.

If you are adding several vendors at once

Firms that sign two or three vendors in a quarter, often after a big client win, face the checklist in triplicate. Stagger the work. Start the vendor most tied to revenue first, and put the others a few weeks behind. Share the standing tasks, such as portal security and record setup, across all of them in one session, and keep vendor-specific work separate. Resist the urge to let the newest vendor slip to the bottom of the pile, because the first 90 days are when relationships form their habits.

Frequently asked questions

Is this checklist for vendors onboarding partners?

No. It is for the partner firm adding a vendor. Vendor-side onboarding is a different workflow.

What is the single most important item?

Naming the relationship owner. Almost every other item slips when the relationship has no owner.

How many vendors is too many?

There is no fixed number. The test is whether you can account for your standing, owners, and dates for every vendor without opening a portal.
