Invoice Processing Fees Are Eating Your Profit (Here's How Much)

Death by a thousand cuts

You send a $5,000 invoice through PayPal. The client pays immediately. You feel great -- until you check your balance and see $4,855. PayPal took $145. On one invoice. Do that 20 times a year and you've handed over $2,900 in processing fees.

Most freelancers treat payment processing fees as a cost of doing business and never think about them again. But the difference between the cheapest and most expensive platform on $100,000 in annual invoices is $1,500-$3,000. That's money going straight from your profit margin into someone else's revenue.

Let's break down exactly what each platform costs and which one makes the most sense for how you work.

Platform fee comparison

Here are the standard rates for the most common payment platforms freelancers use. All rates are for domestic (US-to-US) transactions as of early 2026.

**PayPal:** - Rate: 2.99% + $0.49 per transaction - Invoicing: Free to send, fee on receipt - Payout: Instant to bank for 1.75% fee, or 1-3 business days free

**Stripe:** - Rate: 2.9% + $0.30 per transaction - Invoicing: Built-in, included in rate - Payout: 2 business days standard, instant for 1% fee

**Square:** - Rate: 2.6% + $0.10 per transaction (in-person), 2.9% + $0.30 (online invoices) - Invoicing: Free invoicing tool - Payout: Next business day free, instant for 1.75% fee

**Wise (formerly TransferWire):** - Rate: 0.4-1.5% depending on method and currency - Invoicing: Basic invoicing included - Payout: 1-2 business days - Best for: International payments

**Direct ACH/bank transfer:** - Rate: $0-$0.25 per transaction (through your bank or accounting software) - Invoicing: Separate tool needed - Payout: 1-3 business days - Catch: Clients need to set it up manually, which adds friction

The real dollar amounts

Here's what each platform takes on common invoice sizes.

**On a $500 invoice:**

| Platform | Fee | You keep | |----------|-----|----------| | PayPal | $15.44 | $484.56 | | Stripe | $14.80 | $485.20 | | Square (online) | $14.80 | $485.20 | | Wise (1%) | $5.00 | $495.00 | | ACH transfer | $0.25 | $499.75 |

**On a $2,000 invoice:**

| Platform | Fee | You keep | |----------|-----|----------| | PayPal | $60.29 | $1,939.71 | | Stripe | $58.30 | $1,941.70 | | Square (online) | $58.30 | $1,941.70 | | Wise (1%) | $20.00 | $1,980.00 | | ACH transfer | $0.25 | $1,999.75 |

**On a $5,000 invoice:**

| Platform | Fee | You keep | |----------|-----|----------| | PayPal | $149.99 | $4,850.01 | | Stripe | $145.30 | $4,854.70 | | Square (online) | $145.30 | $4,854.70 | | Wise (1%) | $50.00 | $4,950.00 | | ACH transfer | $0.25 | $4,999.75 |

**On a $10,000 invoice:**

| Platform | Fee | You keep | |----------|-----|----------| | PayPal | $299.49 | $9,700.51 | | Stripe | $290.30 | $9,709.70 | | Square (online) | $290.30 | $9,709.70 | | Wise (1%) | $100.00 | $9,900.00 | | ACH transfer | $0.25 | $9,999.75 |

The pattern is clear: the bigger the invoice, the more the percentage-based fee stings. On $10,000, PayPal takes nearly $300 while a bank transfer costs a quarter.

Annual impact on $100K in revenue

Let's say you invoice $100,000/year across 50 invoices ($2,000 average).

• **PayPal:** ~$3,014 in fees
• **Stripe:** ~$2,915 in fees
• **Square (online):** ~$2,915 in fees
• **Wise:** ~$1,000 in fees
• **ACH transfer:** ~$12.50 in fees

The difference between PayPal and ACH: $3,001.50 per year. That's a vacation. That's a chunk of retirement savings. That's three months of health insurance premiums.

Even switching from PayPal to Wise saves over $2,000 annually. On the same revenue, doing the same work, with the same clients.

International transfer fees: the hidden multiplier

Domestic fees are annoying. International fees are brutal.

**PayPal international:** 2.99% + $0.49 + currency conversion fee of 3-4%. A $5,000 international invoice can cost $350-$375 in total fees. That's 7-7.5%.

**Stripe international:** 2.9% + $0.30 + 1% for international cards + 1% for currency conversion. Total: ~4.9% + $0.30. On $5,000, that's $245.30.

**Wise international:** This is where Wise dominates. Fees run 0.4-1.5% with the mid-market exchange rate (no markup). A $5,000 international transfer might cost $25-$75 total. That's 0.5-1.5% versus PayPal's 7%.

If you have even one international client, Wise should be in your toolkit. The savings on a single $5,000 international invoice ($275-$350 saved versus PayPal) pays for itself immediately.

Should you pass fees to clients?

This is a polarizing topic. Here's the practical breakdown.

**Arguments for passing fees to clients:** - Credit card fees are a cost the client's payment method creates - Many industries (legal, medical, contractors) add a processing surcharge - It preserves your margin on every invoice - Most clients won't even notice a 3% surcharge

**Arguments against:** - It looks nickel-and-dime on small invoices - Some clients find it unprofessional - It adds complexity to your pricing - In some states, credit card surcharges have legal restrictions

**The middle ground that works:** Build processing fees into your rates. If your target rate is $100/hr and you expect 2.9% in fees, price at $103/hr. The client sees a clean number, you absorb the fee, and your effective rate stays where you want it.

Alternatively, offer a small discount (2-3%) for ACH or wire transfer payments. This incentivizes the cheaper payment method without adding a surcharge. Clients feel like they're getting a deal, and you save on fees.

Which platform wins for each situation

**Best for simplicity and client experience: Stripe.** Clean invoices, easy for clients to pay, reliable payouts. The 2.9% + $0.30 is the cost of convenience.

**Best for international payments: Wise.** Not even close. If you work with clients outside the US, Wise saves hundreds to thousands per year on currency conversion alone.

**Best for in-person services: Square.** If you do any work that involves on-site invoicing or payment at delivery, Square's 2.6% + $0.10 in-person rate is the lowest of the card-based platforms.

**Best for maximum savings: ACH/direct transfer.** If your clients are willing to set up bank transfers, this is essentially free. Works best with long-term retainer clients who pay the same amount monthly.

**Best for large invoices ($5K+): Wise or ACH.** When a single transaction fee hits $150-$300, it's worth the extra friction to use a lower-cost platform. Many freelancers use Stripe for small invoices and Wise or ACH for large ones.

The hybrid approach

Most successful freelancers don't pick one platform -- they use two or three strategically.

• **Retainer clients (monthly, predictable):** ACH transfer. Low friction once set up, near-zero fees.
• **Project invoices under $2,000:** Stripe. The convenience is worth the ~$58 fee. Clients pay faster when it's easy.
• **Project invoices over $5,000:** Wise or ACH. At this level, the fee savings ($95-$145 per invoice over Stripe) justify asking the client to use a different method.
• **International clients:** Wise, always. The currency conversion savings alone make it the only rational choice.

This approach on $100,000 in mixed invoices can bring your total annual fees down to $800-$1,200 instead of $2,900-$3,000. That's a $1,700-$2,100 difference for about 30 minutes of setup time.

Stop ignoring this number

Payment processing fees are one of the few business costs you can cut significantly without changing anything about your work, your clients, or your rates. You don't need to work harder or find new clients. You just need to pick the right payment rail for each situation.

Run the numbers on what you paid in fees last year. If it's over $1,500 and you're using a single platform for everything, you're leaving money on the table.
