What electronic invoice means
The phrase 'electronic invoice' describes how a bill is created and delivered, not a separate payment network or fee category. You will see it in accounting software, an emailed PDF or a customer portal, and in contracts or workflows that specify digital billing. In each case, it is a bill sent electronically instead of on paper.
An electronic invoice can include a link or instructions for payment, but sending the invoice does not itself charge a card. If your customer pays by card, the payment method determines processing costs; ACH and check payments follow different payment paths. The rest of this page explains digital invoices, the primary term for this concept.
What a digital invoice is
A digital invoice is a bill you create and deliver electronically instead of printing and mailing it. It lists what your customer owes, such as products or services, quantities, prices, a due date, and payment instructions. You might send it as a PDF or provide a link to an invoice hosted online.
The term also covers structured electronic invoices that transfer invoice data directly between business systems. That is different from a PDF attachment, which still needs a person or software to read and enter its details. Invoice-to-pay describes a broader workflow that can include receiving, approving, paying, and reconciling invoices.
The invoice delivers the bill; the payment method determines the processing cost.
How it works
You prepare the invoice with the customer, line items, amount due, and payment terms, then send it by email or share a secure online link. The customer opens it, reviews the balance, and selects an available payment method. The invoice system records whether it is unpaid, paid, or past due.
Payment choices depend on the service you use. They can include credit or debit cards, ACH bank payments, and digital wallets. Some systems also support recurring invoices, reminders, and automatic charges using a stored payment method. Match each payment to its invoice number so you can reconcile deposits against what customers owe.
What it means for your costs
Sending an invoice does not have one standard fee across the industry. Your cost comes from the service you use and, most importantly, how the customer pays. A card payment made through an online invoice is a card-not-present transaction, with costs that include interchange, network fees, and your processor's markup. Only the markup is negotiable.
An ACH option gives your customer a way to pay from a bank account rather than by card. ACH has its own pricing and return rules, so compare the actual charges for each payment method rather than assuming one is always cheaper. For eligible business card payments, sending Level 2 or Level 3 data can qualify the transaction for a lower interchange category.
How invoices affect cash flow
An email or payment link lets a customer review and pay without mailing a paper check, while reminders give you a record of follow-up. Neither feature guarantees a payment by the due date. Set clear terms on the invoice and track unpaid balances so you know which customers need a reminder and which payments still need to be matched to deposits.
Where it goes wrong
A digital invoice can still create manual work if its details do not match your accounting records. Check customer names, invoice numbers, line items, tax, and due dates before sending. For a B2B sale, confirm that the buyer can use the payment method you offer and that your system records the payment against the correct invoice.
What you can actually change
- Offer payment choice. Show available card and ACH options on the invoice. Compare their actual processing charges before steering customers toward one method.
- Set clear terms. Include the due date, invoice number, itemized amount, and payment instructions. Use reminders to follow up on unpaid invoices.
- Reconcile each payment. Match deposits to invoice numbers and compare payment-related charges with your merchant statement and pricing terms.
Frequently asked questions
Is an electronic invoice the same as a digital invoice?
Yes. Electronic invoice and digital invoice are two names for a bill created and delivered in digital form.
Does an electronic invoice mean an automatic payment?
No. The invoice is a request for payment, while the customer makes a separate payment. A payment link can be included, but sending the invoice alone does not charge a card.
Does calling it an electronic invoice change your processing fee?
No. The invoice format does not set the processing fee. The payment method, such as a card or ACH, determines the payment costs.
