How to Pay Contractors Online in 2026

Choosing the right payment method

BILL

Tipalti

Ramp

For US-based contractors, ACH bank transfer is the default: free, reliable, and creates a clear payment record in your accounting software. Most bill payment platforms (Melio, BILL, QuickBooks Bill Pay) support ACH to any US bank account. The contractor provides routing and account number once; you pay on invoice without re-entering details.

Credit card payment via Melio is worth considering if you want to extend your payment float, pay the invoice with your card on statement due date while the contractor receives ACH within 2 days. The 2.9% Melio fee is the cost; compare it to your card's rewards rate and the value of 30-45 extra days of float.

For international contractors, options include: PayPal or Wise (fast but no accounting sync), BILL international wire transfers ($19.99/transfer), or Tipalti for companies paying 20+ international contractors who need automated tax form collection.

1099 tracking: the compliance step most businesses miss

If you pay a US-based contractor $600 or more in a calendar year, you must file a 1099-NEC with the IRS and send a copy to the contractor by January 31. Penalties for missing or incorrect 1099s range from $50 to $290 per form.

The cleanest approach: collect a signed W-9 from every contractor before making the first payment. Store it on file. At year-end, any contractor who received $600+ gets a 1099. Most accounting software (QuickBooks, Xero) and AP tools (BILL, Tipalti) generate 1099s automatically from payment records, but only if the vendor record is tagged as a 1099-eligible contractor from the start.

BILL handles 1099 generation for domestic contractors natively. Tipalti handles both 1099-NEC (domestic) and 1042-S (foreign contractor withholding) automatically. Melio does not generate 1099s, handle these in your accounting software or with a tax service.

Best tools by contractor payment volume

Under 10 contractors/month: Melio (free) is usually sufficient. Pay by ACH or credit card, sync to QuickBooks, handle 1099s in QuickBooks at year-end. No monthly subscription needed.

10-100 contractors/month: BILL adds approval workflow layer that matters at this volume, useful when payments exceed $1,000 and a second set of eyes is needed. BILL also handles domestic 1099 generation. At $45-55/user/month, the subscription is justified once payment volume or average invoice size warrants the control. See our BILL review for setup details.

100+ contractors or any international contractors: Tipalti's vendor self-onboarding portal eliminates manual work of collecting banking details from large contractor rosters. Automated W-9/W-8 collection and 1099/1042-S generation is a meaningful time-saver at this volume. See our Tipalti review.

International contractor payments: the practical options

Wise (formerly TransferWise): Best for occasional international payments where speed matters more than accounting integration. Transfers are typically cheaper than bank wires and arrive within 1-2 business days. Downside: no direct QuickBooks or Xero sync, record payments manually.

BILL international payments: $19.99 per wire transfer, 130+ currencies, QuickBooks and Xero sync. Good for companies making 5-20 international contractor payments per month without needing automated tax compliance.

Tipalti: Purpose-built for companies paying 20+ international contractors regularly. Handles W-8 collection, OFAC screening, local payment rails, and 1042-S generation. The $449+/month cost is justified when compliance automation replaces meaningful staff time.

PayPal: Convenient for contractors who prefer it but creates accounting headaches, fees are non-transparent, reconciliation is manual, no direct accounting sync. Use as a last resort.

Choosing between contractor payroll tools and AP tools

Two distinct software categories handle contractor payments, and mixing them up creates compliance gaps that surface at the worst time - usually January when 1099s are due. Payroll and contractor tools (Gusto, Deel, Remote, Rippling) are built around the employment relationship. They track worker classification, manage benefits eligibility checks, collect and store W-9 and W-8BEN forms automatically, handle local-currency payroll internationally, and generate 1099-NEC or country-equivalent tax documents at year end. Pricing runs $6-20 per contractor per month depending on the platform and whether the contractor is domestic or international.

AP automation tools (BILL, Ramp, Melio) are built around invoice processing. They route invoices through approval workflows, sync payments to your accounting system, and push remittance data to your general ledger. They do not manage worker classification or collect tax forms natively - that work falls on your finance team. BILL does have a 1099 preparation workflow, but you still need to collect W-9s separately unless you use their vendor onboarding portal.

Use a payroll or contractor tool when you have ongoing relationships with contractors paid on a regular cadence, when contractors are outside the US and you need local compliance, or when your active contractor headcount exceeds 10. Use an AP tool when contractors are treated as vendors paid on invoice, payments are irregular or project-based, or those contractors already sit in your vendor master alongside regular suppliers. Many businesses end up using both: Gusto or Deel for recurring contractors and BILL for one-off vendor payments.

Step-by-step: paying a domestic contractor for the first time

Before you send a single dollar, collect a completed W-9. You can email the contractor the IRS PDF (Form W-9, available at irs.gov at no cost) or use BILL's vendor onboarding portal, which sends the contractor a guided link to submit their W-9 digitally and stores it against their vendor record. Once you have the form, verify the TIN against the contractor's legal name using the IRS TIN Matching System - it is free, takes about 24 hours for bulk submissions, and protects you from backup withholding liability if the number turns out to be wrong.

Set the contractor up as a vendor in your AP system with their preferred payment method. ACH is the default choice - it is free in most tools and settles in 1-3 business days. Add their bank routing and account numbers or invite them to connect their bank account directly through the tool's self-serve portal. Then create the payment against their invoice. If the contractor does not send formal invoices, most tools let you create a one-time payment manually. Route the payment through your standard approval workflow before it goes out.

Track cumulative payments per contractor throughout the year. Any contractor you pay $600 or more in a calendar year for services requires a 1099-NEC filed by January 31 of the following year. BILL, Gusto, and QuickBooks all have 1099 preparation workflows that pull payment totals automatically and generate the forms - you review, confirm, and e-file through the platform. If you are using a tool without that workflow, export a year-to-date payment summary per vendor each December and run it against the $600 threshold manually before the filing window opens.

Same-day payment options for contractors who need fast pay

Contractors are not on your payroll cycle. Many invoice on delivery and expect payment within a few days - especially freelancers and independent consultants who manage their own cash flow tightly. Standard ACH through BILL or Melio takes 3-5 business days, which is fine for planned payments but creates friction when a contractor delivers work on Friday and wants payment before the weekend.

Faster options exist at different price points. Same-day ACH is available through BILL and Ramp on eligible plans, typically for a $2-5 fee per transaction. Instant transfers through Gusto or Deel can fund a contractor's bank account within minutes - fees vary by plan but are generally under $5. Zelle for Business works same-day for smaller amounts and has no fee, but it does not sync to your accounting system and 1099 tracking is entirely manual. Wire transfers settle same-day domestically for $15-25 per wire, which is cost-effective only for larger invoices where the fee is immaterial.

For contractors who consistently need fast payment, Gusto's flexible payout option draws from your connected bank account immediately rather than waiting for a standard processing window. The practical default for most businesses: pay contractors on net-7 terms using standard ACH, which balances speed with cost. If a contractor requires same-day payment, discuss it before the engagement starts and factor any wire or instant-transfer fees into your project budget. Surprises at invoice time create friction that damages the working relationship.

FAQ: paying contractors online

Can I pay contractors through Venmo or PayPal for business? Technically yes for domestic payments. PayPal for Business integrates with QuickBooks and some other accounting tools, which at least gives you a payment record. Venmo does not integrate with any accounting system and has no business-grade approval workflow. The compliance risk with both: PayPal will issue a Form 1099-K to any contractor you pay $600 or more through their platform, which sits alongside whatever 1099-NEC your own system generates. That creates duplicate reporting confusion - the contractor receives two forms covering overlapping income, and they have to reconcile it on their tax return. Stick to tools with a clear 1099-NEC workflow and a single source of truth for annual payment totals.

What is the $600 threshold for 1099s? Any contractor you pay $600 or more in a calendar year for services requires a 1099-NEC, filed by January 31 of the following year. This applies regardless of payment method - ACH, check, wire, or digital wallet. The threshold is per contractor, not per invoice.

If I pay a contractor via credit card or through their payment processor, do I still owe a 1099? No. When payments go through a credit card, debit card, or a third-party payment network, the payment processor is required to file a 1099-K - you are not required to file a 1099-NEC for those same payments. This is a legitimate way to reduce 1099 filing volume for low-dollar or occasional contractors. Just confirm the processor actually issues the 1099-K before you assume your filing obligation is covered.

Do LLCs need a 1099? It depends on the LLC's tax classification, which the contractor's W-9 will tell you. Single-member LLCs treated as sole proprietors: yes, file a 1099-NEC. Multi-member LLCs: yes. LLCs that have elected S-corp or C-corp tax treatment: generally no - with two exceptions. Attorneys and healthcare providers receive a 1099-NEC regardless of corporate status. This is exactly why collecting a current W-9 before the first payment matters: the tax classification box on the form tells you whether you have a filing obligation before you reach the $600 mark.
