Paying an invoice is straightforward once you know what to look for on the document and which payment method to use. Most invoices include clear instructions from the sender, but the specific steps depend on whether you’re paying by bank transfer, credit card, check, or through an online platform. Here’s how to handle the process from start to finish.
Check the Invoice Details First
Before you send any money, take a minute to verify what’s on the invoice. A properly formatted invoice should include an invoice number, the date it was issued, the sender’s business name and contact information, a description of the goods or services provided, the total amount due, payment terms (the deadline), and instructions for how to pay.
If the invoice references a purchase order (PO) number, match it against your own records to confirm the amount and the vendor are correct. This is especially important in a business setting where multiple orders may be in progress at once. If anything looks off, like a dollar amount that doesn’t match your agreement or bank details that differ from previous invoices, contact the vendor directly using a phone number or email you already have on file, not the contact info on the suspicious invoice itself.
Understand the Payment Deadline
The invoice will typically state its payment terms near the top or bottom of the document. The most common format is “Net 30,” which means payment is due within 30 days of the invoice date. You may also see Net 10, Net 15, Net 60, or Net 90 depending on the industry. Construction invoices, for example, often allow up to 90 days, while retail and food service invoices are frequently due immediately or within a few days.
Some invoices offer an early payment discount, written as something like “2/10 Net 30.” That means you can take a 2% discount if you pay within 10 days, otherwise the full amount is due in 30. If cash flow allows, that discount is almost always worth taking. Late payments, on the other hand, may trigger penalty fees outlined on the invoice. About 60% of invoices in the United States are paid late, with payment arriving an average of 7 days past the deadline. Staying on top of due dates protects your relationships and your credit terms with vendors.
Choose Your Payment Method
The invoice itself will usually specify which payment methods the sender accepts. Here are the most common options and what to expect from each.
Bank Transfer (ACH)
ACH transfers move money electronically between U.S. bank accounts and are one of the most popular ways to pay business invoices. You’ll need the vendor’s bank name, routing number, and account number, which should be listed on the invoice. Most business bank accounts have ACH capabilities built in, and you can initiate the transfer through your bank’s online portal. Processing typically takes one to three business days, and fees are low, often around 1% or less when processed through a payment platform.
Credit or Debit Card
Many invoices include a link or button that takes you to an online payment page where you can enter your card information. Invoicing platforms like QuickBooks, Zoho, Xero, and Wave integrate with payment processors such as Stripe and PayPal to make this seamless. You click the “Pay Now” button in the email, enter your card details, and you’re done. The vendor typically absorbs the processing fee (around 3% for credit cards), though some pass it along as a surcharge. Card payments usually clear within one to two business days.
Online Payment Platforms
If the invoice specifies PayPal, Venmo (for smaller transactions), or another platform, you can log into your account on that service and send the payment to the vendor’s email or account ID. PayPal is especially common for freelancers and small businesses. If you already have funds in your account or a linked bank account, you can often avoid extra fees on your end.
Check
Some vendors, particularly in traditional industries, still accept paper checks. Write the check for the exact amount on the invoice, note the invoice number on the memo line, and mail it to the address listed on the invoice. Allow extra time for mailing and processing. If your deadline is tight, a check may not be the best option since it can take a week or more to arrive and clear.
Wire Transfer
Wire transfers are less common for routine domestic invoices because they cost more and take longer to set up. They’re primarily used for large transactions or international payments. Your bank will need the recipient’s account number, routing number (or SWIFT code for international transfers), and bank name. Domestic wires often process the same day, while international wires take one to five business days.
How to Pay an International Invoice
Cross-border invoices add two complications: currency conversion and higher fees. A standard SWIFT bank transfer for an international invoice typically costs $25 to $40 per transaction, and the exchange rate your bank offers usually includes a markup over the mid-market rate. That markup can quietly add 2% to 4% to the total cost.
International transfer providers like Wise, OFX, and Payoneer specialize in moving money across borders at lower cost. A $1,000 transfer converted to euros through one of these services might cost $0 to $7 in fees, compared to $25 or more through a traditional bank. These platforms also tend to offer exchange rates much closer to the mid-market rate. If you regularly pay overseas vendors, setting up an account with one of these services can save meaningful money over time.
When paying internationally, confirm the currency the vendor expects. If the invoice says “€5,000,” you need to send euros, not the dollar equivalent, unless the vendor has specified otherwise. Also double-check the recipient’s SWIFT/BIC code and IBAN (International Bank Account Number) if the invoice provides them. A single wrong digit can delay or misdirect the payment.
Paying Through an Online Invoice Link
The simplest way to pay an invoice today is through an emailed link. Many businesses send invoices through platforms like QuickBooks, FreshBooks, or Xero, and the email includes a button that takes you directly to a secure payment page. From there, you select your payment method (card, bank transfer, or platform balance), confirm the amount, and submit. You’ll typically receive a confirmation email immediately, and the payment shows as recorded in both your and the vendor’s accounting systems automatically.
If you use accounting software yourself, paying through these integrated links can save time on bookkeeping since the transaction syncs with your records.
Spot a Fake Invoice Before You Pay
Invoice fraud is common enough that it’s worth a quick check before you pay any invoice, especially one you weren’t expecting. The FTC warns that scammers frequently send fake invoices hoping recipients will pay without verifying. Red flags include a generic greeting (“Dear Customer” instead of your name), an invoice for a product or service you don’t recognize, pressure to click a link to “update your payment details,” and sender email addresses that look slightly off from the real company’s domain.
Legitimate companies won’t ask you to click a link to update your payment information out of the blue. If you receive an invoice and aren’t sure it’s real, go directly to the vendor’s website or call them using a number you find independently. Never use the contact information in the suspicious email itself. And if the invoice asks you to send payment to different bank details than you’ve used before with that vendor, verify the change with a phone call before transferring anything.
Keep a Record of Every Payment
Once you’ve paid, save the confirmation. Whether it’s a transaction ID from your bank, a receipt email from PayPal, or a screenshot of a completed payment screen, this documentation protects you if there’s ever a dispute about whether or when you paid. Note the invoice number, the amount, the date paid, and the method you used. If you’re running a business, your accounting software can track this automatically, but even for personal payments, a simple folder in your email or a spreadsheet works.
If the vendor doesn’t send a receipt or payment confirmation, it’s reasonable to email them and ask for written acknowledgment that the payment was received.
