Whether you’re a global brand, creative agency, or platform managing external partnerships, you’ve likely experienced the pain of onboarding vendors.

It’s 2025, and yet the process is still riddled with friction: long email chains, manual W-9 collection, compliance delays, tax errors, and endless “how do I get paid?” emails. This is inefficient, putting a drag on campaign speed, finance team productivity, and your partner relationships.

Let’s break down what’s slowing you down and how modern organizations are 10x’ing their onboarding workflows by improving your process, without having to rebuild it from the ground up.

Why Vendor Onboarding Is Broken (Still)

The term “vendor onboarding” evokes procurement checklists and legal formality. But in marketing, the term encompasses a much broader, and faster-moving, universe of partners: creators, freelancers, influencers, content studios, affiliate partners, live event staff, and more.

Here’s why traditional onboarding just doesn’t work:

1. It Was Built for Large Vendors, Not Fast-Moving Campaigns

Traditional procurement systems (like Coupa, Ariba, or Zip) were designed for long-term suppliers, not a photographer you need to pay $1,500 this week. The traditional procurement process introduces unnecessary friction for one-time or short-term partners, often referred to as long tail vendors.

2. Tax and Compliance Checks Are Manual and Fragmented

Whether it’s collecting W-9s/W-8s or running AML/OFAC screening, finance and compliance teams often step in manually. The result? Slow review cycles, errors, and partner frustration, especially with international vendors.

3. Marketing and Finance Are Out of Sync

Marketers are incentivized to move quickly. Finance is incentivized to reduce risk. When both teams operate in silos, onboarding becomes a bottleneck that delays campaigns and undermines budget visibility.

“Our finance team has a million things they do. Eliminating onboarding and general ledger entries for each creator was a huge time saver.”
— Wyatt Lowe, Sr. Director of Performance Marketing at MaryRuth’s

What a 10x Faster Onboarding Experience Looks Like

If you want to move at the speed of modern marketing, here’s what best-in-class vendor onboarding needs to deliver:

✅ One-Time Setup Per Category

The fastest-growing teams reduce vendor volume at the AP level by consolidating under a Master Vendor Model. Rather than onboarding every creator, influencer, or freelancer, they onboard Lumanu as their single one vendor who handles the rest.

“Lumanu acted as our single vendor to manage all onboarding and compliance. It made our work across Marketing, Finance, and Legal more efficient while reducing risk.”
— Danielle Ford, VP, Business & Legal Affairs at Warner Music

✅ Guided, Self-Serve Partner Onboarding

Creators and small vendors don’t want to read PDF instructions or email in their tax forms. They need mobile-friendly, intuitive onboarding flows that:

• Walk them through bank + tax info securely

• Validate IDs and banking formats globally

• Provide real-time progress updates

• Are fully white-labeled to your brand
  
  

✅ Automated Compliance

Best-in-class, seamless onboarding (so easy it can be done from an iPhone) includes built-in:

• W-8/W-9 collection

• VAT/Tax ID validation

• OFAC, AML, and PEP screening

• Jurisdictional logic for withholding taxes

Finance and compliance shouldn’t have to manually review and approve every vendor. Platforms like Lumanu bake compliance checks into the onboarding flow.

✅ Real-Time Integration With Payments

Onboarding shouldn’t be disconnected from payout creation. The moment a vendor completes their profile, your team should be able to issue payments with pre-approved budgets, approvers, and policies in place.

“We went from dozens of POs, vendors, and invoices for each campaign to one vendor, one PO, one invoice. Lumanu has been a game changer.”
— Lexie Barnhorn, Head of Influencer Marketing at Notion

The Hidden Costs of Slow Onboarding

Delays in vendor onboarding not only lead to hours of support time across teams, they damage your relationships introduce financial and brand risk:

• Vendor churn: Creators are less likely to work with you again

• Support overhead: “Where’s my payment?” tickets skyrocket

• Delayed campaigns: Talent drops out before paperwork is done

• Compliance risk: Improper tax collection or fraud exposure

• Finance friction: Poor audit trails and inconsistent vendor records

All of this creates an unnecessary burden on teams already stretched thin.
