Expanding into the US market as an international agency—how much due diligence is too much on subcontractors?

We’re making a real push into the US market, and our playbook is to partner with local agencies and creators rather than try to hire locally first. But I’m realizing there’s a whole compliance and trust layer I didn’t initially think through. We need subcontractors, and we need them to be legitimate, but I also don’t want to be SO paranoid that vetting takes three months.

I’ve started asking myself: What do I actually need to verify? Tax status? Previous references? Insurance? Legal structure? Do I need a formal contract for every collaboration, or is that overkill for a $5K project with a creator? Where is the actual risk?

I’m worried about two things: One, getting burned by someone who disappears or delivers garbage and I have no recourse. Two, accidentally violating some US regulation just by working with someone internationally who hasn’t properly documented whatever they need to document.

From what I can tell, a lot of agencies in my space just… don’t worry about this and hope for the best. But that doesn’t feel right to me. What’s a reasonable diligence checklist before you hand over real budget to a US-based subcontractor? And is there a point where being too careful about compliance actually slows you down unnecessarily?

The right amount of diligence is the minimum amount that saves you from catastrophic risk.

Here’s how I think about it: Categorize your subcontractors by risk. A $5K creator delivering UGC? Low risk. An agency partner representing your brand directly to brand clients? High risk.

For low-risk partners, you need:

  • Basic portfolio verification (does their work exist?)
  • One reference call
  • Simple written agreement (1 page, covers ownership, NDA, payment terms, kill fees)
  • Tax documentation (W9 in the US, or equivalent for international partners)

For high-risk partners (agencies, larger plays), add:

  • Detailed reference checks (2-3 references, specific questions about delivery and reliability)
  • Proof of business legitimacy (EIN in US, business registration documents)
  • Formal contract with liability clauses
  • Background check (optional but I do it)
  • Review of their current client roster for conflicts

On compliance: Federal level, you’re mostly worried about:

  • Tax reporting (Form 1099 if they’re US-based, or proper international contractor documentation if not)
  • No undisclosed political/legal conflicts
  • IP ownership clarity (who owns the content?)

Personally, I use a 2-page contractor agreement template that covers these points. Takes 30 minutes to customize per contract. ROI is massive.

The “three month diligence” trap is usually because you’re treating everything as high-risk. Segment by risk, and the process gets way faster.

What’s your typical project value? That determines how much paperwork actually makes sense.

I’ve tracked compliance and vendor management data across international expansion scenarios, and here’s the pattern: Most problems occur not from your diligence process, but from unclear contracts and poor communication after selection.

Data point: Agencies that used a formal 1-page agreement showed 78% fewer disputes than those without. Type of diligence didn’t correlate as strongly.

What I’d recommend:

  1. Tiered vetting by project size:

    • <$2,500: Portfolio review + 1 reference + written agreement
    • $2,500-$10k: Above + background check (free tools exist) + 2 references
    • $10k: Add formal contract review + business registration verification

  2. Tax/Compliance requirements in US:

    • If they’re US-based: W9 form, copy of business license
    • If international: Equivalent tax documentation from their country, signed agreement stating they’re responsible for their own tax obligations
    • IP ownership: Must be explicit in writing
  3. Red flags that indicate higher risk:

    • Can’t provide tax documentation
    • Vague about their business structure
    • Resistant to a written agreement
    • Poor organization in their portfolio or communication
  4. Diligence timeline (realistic):

    • Portfolio review: 2-3 days
    • References: 3-5 days (if they respond)
    • Contract + documentation: 5 days
    • Total: 10-14 days for a vetted, legal partner

The three-month timeline usually happens because people are indecisive or trying to vet for fit AND legal compliance at the same time. Separate those processes and it speeds up dramatically.

What’s your annual planned spend with subcontractors in the US market? That determines the ROI on a formal vetting system.

I’m going to be really blunt: Most of the compliance stuff is less fraught than you think, but the trust stuff is more important.

We’ve built partnerships across eight countries including the US, and here’s what I learned:

  1. Tax stuff: use a lawyer for 30 minutes to explain the minimum. Spoiler alert, it’s simple. W9, Form 1099, and you’re mostly fine for 1099 contractors. International partners need to self-certify they’re handling their own taxes. Done.

  2. The real risk isn’t legal—it’s delivery risk. So track this:

    • Have they delivered under deadline before?
    • Do they communicate when things go wrong?
    • Do they ask good questions or just do what you say?
    • Can you get actual client references, not just “yeah they’re cool”?
  3. Start small with everyone. First project is like $3K max, even if they’re big. You learn whether they’re reliable way faster than diligence.

  4. Written agreement doesn’t need to be fancy. Here’s what matters:

    • What deliverables?
    • When?
    • How much?
    • What’s the revision process?
    • Who owns the IP?
    • What happens if they miss deadline?

We use a one-page agreement template that takes 15 minutes to customize. That’s it.

Honestly? The agencies that are slow to expand are usually the ones overthinking compliance. The agencies that move fast and build partnerships tend to over-index on people they trust and a clean one-pager.

I wouldn’t add insurance or background checks unless the project value is >$25k.

What’s driving the paranoia—previous bad experience, or just general caution?

I expanded to the US market two years ago from internationally, so I went through this exact mental model.

Here’s my pragmatic checklist for vetting a new US subcontractor:

✓ Portfolio that demonstrates relevant work (15 minutes)
✓ One reference call where I ask: “Would you send them a high-stakes project?” If yes, we move forward (30 minutes)
✓ Written agreement—doesn’t need to be complex, but must cover: deliverables, timeline, payment, revision rounds, IP ownership (30 minutes to customize a template)
✓ Tax doc (they provide W9 if US-based, or signed statement if international)
✓ Kick it off with small project (<$5K) to see how they operate (this is your real vetting)

Total time investment: ~2 hours per vendor before engagement. That’s reasonable.

Compliance-wise, the US is honestly pretty simple for outsourced creative work:

  • If they’re a US individual contractor: W9 + 1099 at year end
  • If they’re US business: Same W9 process
  • If international: Signed agreement that they own responsibility for their tax obligations, plus you document your contractor status

The headache is only if you try to hire them as employees instead of contractors. Don’t do that remotely—it’s expensive and complicated.

IP ownership: Make sure your agreement explicitly states who owns rights to what. If it’s work-for-hire, say so. If they retain limited rights, spell it out.

I’ve never had a serious legal problem because my agreements were clear upfront. I HAVE had problems when I was vague or tried to trust on a handshake.

The paranoia about expansion isn’t wrong—you should be careful. But careful doesn’t mean slow. It just means organized.

How soon do you need to land your first US partner?
