How to pay international contractors

Worker classification

Misclassifying someone as a contractor when their home country’s laws consider them an employee creates liability you don’t want. Every country draws this line differently.

The UK uses IR35 rules that look at whether contractors would be employees if you hired them directly. Germany cares about whether workers control their own schedules and serve multiple clients. Brazil leans toward employee status unless you can clearly demonstrate the relationship meets contractor criteria. Your contractors should maintain their own business registration, send you proper invoices, and ideally work with other clients besides you.

Tax documentation

Before sending that first payment, collect a W-8BEN from individual contractors or W-8BEN-E from foreign entities. These forms live in your files, not with the IRS. They document foreign status and explain why you’re not withholding taxes. Keep them for at least four years, because the IRS can ask for them during audits. An expired or missing form when that happens creates headaches you can easily prevent.

Request these forms during onboarding, before any money moves. Trying to chase down tax documents from someone who finished their project three months ago and moved on to other work is a frustration worth skipping entirely.

International wire transfers

Bank-to-bank transfers work virtually anywhere and come with solid security, which explains why they remain popular. The costs just add up in ways that aren’t always obvious upfront. Sending fees typically run $30 to $50 per transaction. The contractor’s bank often adds receiving fees on their end too. The bigger expense usually comes from exchange rate markups. Banks commonly mark up rates by 2-3%, so a $5,000 transfer can lose $150 to conversion alone before it arrives.

Timing matters too. Funds typically take three to five business days, sometimes longer when multiple correspondent banks get involved. Wire transfers make sense for large, one-time payments where a flat fee becomes negligible as a percentage. Sending $25,000 for a completed project? A $45 fee barely registers. That same fee on a $500 monthly retainer means 9% of the payment disappears before your contractor sees anything.

Digital payment platforms like Melio

Platforms like Melio have become the go-to choice for ongoing contractor relationships because they move money more efficiently than traditional banks.

Melio handles international and domestic payments from a single dashboard. You don’t need separate systems for different vendor types. When you pay in a contractor’s local currency, you see competitive exchange rates before confirming the payment. No guessing about what the transfer will actually cost.

Same-day delivery works for local currency payments submitted before 2 p.m. ET. USD payments arrive in one to three business days with fast transfer, or four to six days with standard. A $20 fee applies to USD payments, which keeps costs predictable for larger transfers.

The credit card option lets you pay contractors with Mastercard or Visa while deferring cash outflow until your next billing cycle. A fee applies, though card rewards often offset part of it. This becomes useful when cash flow is tight but you need to pay contractors on time. Contractors receive funds directly to their bank without creating a Melio account or going through extra verification steps.

Payments sync with QuickBooks Online and Xero, cutting down manual reconciliation at month-end. Businesses moving $100,000 or more internationally per quarter can access Melio Platinum for volume discounts and dedicated support.

Paying international contractors by credit card

Credit card payments offer something other methods don’t: the ability to pay contractors immediately while deferring actual cash outflow until the next billing cycle. This separation between when contractors get paid and when money leaves your account creates flexibility that proves valuable during uneven revenue periods or when several contractor payments hit at once.

Most international contractors don’t accept credit cards directly, which historically limited this approach. Platforms like Melio handle this by processing the card payment on your end and delivering funds to contractors via bank transfer. You capture card benefits without requiring contractors to set up merchant accounts or payment processing.

The math deserves consideration. A 2.9% processing fee sounds steep until you factor in the benefits. Cash back rewards of 1.5-2% reduce the effective cost considerably. The float from deferring payment 30-45 days has real value for businesses managing cash flow carefully. On a $5,000 contractor payment, a 2.9% fee costs $145, but 2% cash back returns $100. Net cost of $45 for potentially six weeks of float.

Card payments also create cleaner expense tracking. They can help businesses meet minimum spend requirements for sign-up bonuses or maintain status with rewards programs. Transaction records sync automatically with accounting software, reducing manual reconciliation compared to wire transfers.

Onboarding

Collect W-8BEN or W-8BEN-E forms before the first payment goes out. Store them securely with restricted access since they contain sensitive tax identification numbers. Update forms if contractors change business structure, like incorporating or switching entity types.

Contract terms

Written agreements should cover scope, payment amounts, currency, schedule, and invoicing procedures. Specify deliverables clearly enough that both parties understand exactly when milestones are complete and payment becomes due.

Currency choice matters more than most businesses realize. USD simplifies your accounting but shifts all exchange rate risk to contractors, who may pad their rates to protect themselves. Local currency payments cost slightly more in conversion but often strengthen working relationships because contractors know exactly what they’re receiving. For ongoing relationships, this clarity can improve retention and reduce rate negotiations down the line.

Payment frequency depends on the work. Project-based engagements typically use milestone payments tied to specific deliverables. Ongoing relationships flow better with monthly schedules that both parties can plan around.

Method selection

Match your method to the situation. Large one-time payments can absorb wire fees without much impact. Ongoing relationships benefit from digital platforms like Melio where costs stay predictable and transfers move quickly. Multiple contractors often justify all-in-one platforms where time savings exceed any subscription costs, especially when compliance gets complex across different jurisdictions.

Record keeping

Keep invoices, payment confirmations, and tax forms for at least four years. Digital records are searchable, take up no physical space, and back up easily. Organized documentation simplifies tax preparation and protects you if audits come up.

Exchange rates

The gap between mid-market rates and bank rates runs 2-4%, representing the biggest hidden cost in international payments. On a $3,000 payment, that’s $60-120 lost to markup alone, separate from transaction fees. Over a year of monthly payments, poor exchange rates can cost more than all other fees combined.

Platforms that offer rates closer to mid-market tend to be significantly cheaper overall. Comparing total cost rather than just transaction fees shows you the true expense of each method.

Fee structures

Flat fees favor larger payments. A $20 fee on $10,000 is 0.2%. On $200, it’s 10%. Percentage fees work inversely. 2.9% matters less on small amounts and more on large transfers. Businesses with varying payment sizes often use different methods for different amounts to keep overall costs down.

Speed

Same-day delivery is available through Melio for local currency payments before 2 p.m. ET. One to three days is typical for fast options. Traditional wires take three to five days, which works fine for payments without urgent timing but gets frustrating when contractors depend on prompt arrival.

Milestone-based

Payment tied to deliverables protects both parties on project work. Contractors receive payment as work progresses rather than waiting until everything’s done. Businesses avoid large upfront payments to unproven partners and limit exposure if relationships end mid-project. Define milestones clearly in contracts, specifying exactly what completion looks like for each phase. This prevents disputes about when payment becomes due.

Monthly retainers

Fixed monthly amounts suit ongoing support with consistent scope. The predictability benefits both sides. Contractors can plan their income. Businesses can plan their expenses. Review retainer arrangements periodically to make sure compensation reflects actual workload. Retainers requiring significantly more hours than expected create friction that damages otherwise productive relationships.

Hourly with invoicing

Time tracking and invoicing works for variable workloads where monthly hours fluctuate significantly. Establish invoicing cadence upfront,weekly, biweekly, or monthly, along with expectations about invoice detail. Clear guidelines about task descriptions, project codes, and supporting documentation prevent the back-and-forth that delays payment processing.
