PaySec + Invoice Simple: Zero Processing Fees for Freelancers and Small Businesses

Marcus C.2026-04-30

How freelancers and small businesses using Invoice Simple are eliminating credit card processing fees with PaySec's Network Offset Pricing.


For freelancers, independent contractors, and small business owners, getting paid should be the simplest part of the work. You do the job, you send the invoice, you collect payment. Invoice Simple has built its reputation on making that process fast and easy -- professional invoices created in minutes, sent from your phone or computer, with built-in payment options that let clients pay right from the invoice.

But simplicity comes at a cost. Invoice Simple's built-in payment processing charges standard rates of around 2.9 percent per card transaction. For a freelancer billing $10,000 per month, that is $3,480 per year in processing fees. For a small business invoicing $50,000 per month, it is $17,400 annually. Those fees eat directly into the money you worked hard to earn.

PaySec brings zero-fee processing to your Invoice Simple workflow. By using Network Offset Pricing on your invoice payment links, you keep 100 percent of every payment your clients send.

What Is the PaySec + Invoice Simple Integration?

PaySec works alongside Invoice Simple by providing NOP-enabled payment links that you add to your invoices. When a client receives your invoice, they click the payment link and see two options: the invoice amount if paying by ACH or bank transfer, or a slightly higher amount if paying by credit card. The small difference on the card price covers the cost of processing. The client chooses, and you receive the full invoice amount regardless of their payment method.

Network Offset Pricing (NOP) is legal in all 50 states and fully compliant with all major card network rules. You continue to create and manage your invoices in Invoice Simple exactly as you do today. The only change is the payment link, which now routes through PaySec and displays dual pricing.

The Real Cost of Processing Fees for Freelancers and Small Businesses

When you are self-employed or running a lean operation, every dollar counts. Processing fees are one of the expenses that many freelancers accept as a cost of doing business without realizing how much they add up over a year.

Monthly InvoicingProcessing RateAnnual Cost
$5,0002.9%$1,740
$10,0002.9%$3,480
$25,0002.9%$8,700
$50,0002.9%$17,400

For a freelance designer billing $10,000 per month, $3,480 per year in processing fees is a new computer, a professional development course, or a month of rent on a coworking space. For a small service business invoicing $25,000 per month, $8,700 is enough to fund a marketing campaign or hire part-time help.

The problem is amplified for freelancers and small businesses because margins are already tight. Unlike large companies that can absorb processing costs across massive revenue, independent workers feel every percentage point directly in their take-home income.

How Network Offset Pricing Works with Invoice Simple

Here is a practical example. You are a freelance web developer and you send a client a $2,500 invoice for a website project. The client clicks the PaySec payment link and sees:

Payment MethodAmount
ACH / bank transfer$2,500.00
Credit card$2,600.00

The client chooses their preferred method. You receive $2,500 for the work you performed, with no processing fee deducted from your payment.

Here are more examples across common freelance and small business invoices:
