  • What "Online Payments" Actually Includes in 2026

Invoicing tools with built-in online payments shorten the gap between sending a bill and seeing money hit the account. The fee, the payout window, and the supported rails are the three numbers that matter. This guide compares the eight tools most U.S. small businesses actually pick and explains what you give up when you trade an embedded payment button for a standalone processor.

Quick Answer
For most U.S. small businesses, Billed, Square Invoices, and Wave deliver the strongest balance of built-in card and ACH payments, transparent fees, and reasonable payout timing. Stripe-powered invoicing (Stripe Invoicing, FreshBooks, Zoho) is the better choice when you need international cards, recurring subscriptions, or richer fraud controls. PayPal Invoicing is acceptable for occasional invoices but is the most expensive on a per-transaction basis.

How we verified this
We cross-referenced published pricing pages from Stripe, Square, Wave, PayPal, Intuit, FreshBooks, Xero, and Zoho against Federal Reserve and Nacha payment data. Fees and limits change. Each rate cited links to the vendor's current pricing or help center page.

Key Takeaways

  • Card invoicing fees cluster around 2.9% + $0.30 (Stripe, Wave) to 3.49% + $0.49 (PayPal). The 60-cent gap is real money on a $50 invoice.
  • ACH on invoices is usually 1% capped at $5 to $10, which makes ACH the right default for invoices above ~$400.
  • Payout timing is 1-2 business days for most tools, but Square Checking and Stripe Instant Payouts can put funds in your account in minutes for a small fee.
  • Request for Payment over FedNow and RTP is the 2026 story: instant, irrevocable, and rich-data, but limited to banks that have turned on the receive side.
  • PayPal's per-invoice fee (3.49% + $0.49) is the highest among the tools we compare. The convenience tax is roughly $0.60 to $1.20 per invoice vs. Stripe-powered alternatives.

Why Built-In Payments Beat External Links

The first time a small business sends an invoice with a "Pay Now" button instead of an emailed PDF and wire instructions, time-to-payment usually drops by days. Intuit's QuickBooks team reports that invoices with online payment options are paid up to 4x faster than paper invoices, and Xero says customers using its online invoice payments get paid up to twice as fast. The mechanism is mundane: a click is closer than logging into bill pay.

Built-in payments also collapse reconciliation. The invoice, the receipt, and the deposit live in the same tool, so a missed payment becomes a flagged invoice instead of a Friday afternoon spreadsheet exercise. That matters more than it sounds. Xero's Small Business Insights data shows U.S. small businesses were paid an average of 7.8 days late in the December 2025 quarter, the shortest delay in four years, driven heavily by tools that pair invoicing with one-click payments and automated reminders.

The tradeoff: you accept the processor your invoicing tool partners with. If you already run Stripe or Square for in-person sales, that constraint is fine. If you have a negotiated rate with a merchant acquirer or you need American Express at par with Visa, a standalone processor plus a pay-link invoice tool will save you money.

What "Online Payments" Actually Includes in 2026

The phrase "online payments" inside an invoicing tool covers four very different rails, each with its own economics.

Cards (credit and debit). The default. Online card-on-file rates in the U.S. cluster around 2.9% + $0.30. The exact rate depends on the processor and whether the card is a rewards card, a corporate card, or an international card. Stripe's published pricing shows 2.9% + $0.30 for standard online cards in the U.S., with 4.4% + $0.30 for international cards. Square Invoices runs 3.3% + $0.30 on its Free plan and 2.9% + $0.30 on Plus, per Square's invoice pricing page.

ACH (bank transfer). The cheap rail for U.S. invoices. Stripe ACH Direct Debit is 0.8% capped at $5, meaning a $10,000 invoice costs $5 instead of $290. Square Invoices ACH is 1% with a $1 minimum, capped at $10 on Plus and Premium per Square's pricing page. PayPal's ACH option for U.S. invoicing is 1.0% capped at $25.

Digital wallets. Apple Pay, Google Pay, Link, and PayPal/Venmo. These usually price the same as cards because they tokenize a card under the hood. The exception is bank-funded wallet payments, which sometimes route as ACH.

Real-time payments (RTP and FedNow). New for most invoicing tools in 2026. Both The Clearing House's RTP and the Federal Reserve's FedNow support Request for Payment (RFP), which delivers an invoice into a customer's mobile banking app for one-click, irrevocable payment. Settlement is in seconds, 24/7. RTP raised its per-transaction limit to $10 million in February 2025, and FedNow lifted its limit to $1 million in summer 2025. Adoption inside invoicing tools is uneven, built directly into bank-owned billing platforms and a few fintechs, still on the roadmap at most SaaS invoicing vendors.

The 8 Best Invoicing Tools With Online Payments

1. Billed: Best Overall for SMBs and Freelancers

Billed packages invoicing, online payments, recurring billing, expense tracking, and time tracking into a single workflow purpose-built for small operations. The pay-now experience sits inside the invoice email and the client portal, accepting cards and ACH without a separate processor account to manage.

Key payment features:

Best for: Freelancers, consultants, agencies, and SMBs that want a finished invoicing-plus-payments workflow without operating a separate Stripe or Square dashboard.

2. Stripe Invoicing: Best for International and Complex Billing

Stripe's hosted invoicing layer plugs into the broader Stripe stack. If you need international cards, multi-currency settlement, customer-specific tax handling, or a programmable invoicing API, this is the strongest choice. The downside is that Stripe Invoicing layers a 0.4% to 0.5% fee on top of the standard Stripe processing rate (per Stripe's published pricing for Billing and Invoicing), which most small operators do not recover in operational benefit.

Best for: Software companies, exporters, and businesses already running Stripe Checkout or Payments who want to consolidate billing.

Drawback: Two-layer fee structure (processing + invoicing surcharge). Less self-explanatory for first-time users.

3. Square Invoices: Best for In-Person + Online Hybrid Sellers

Square Invoices ties the same processor that runs the point-of-sale terminal to a free invoicing tool. The Free plan supports unlimited invoices and online payments at 3.3% + $0.30 for cards. The Plus plan ($20/month per Square's pricing) drops the card rate to 2.9% + $0.30 and caps ACH at $10 per transaction.

Square Checking accounts move funds instantly at no extra cost, which is the only meaningfully different payout experience among the tools in this list.

Best for: Hybrid businesses (retail, food, service) that already use Square at a counter and want a matched invoicing experience.

4. Wave Invoicing: Best Free Option With Payments

Wave keeps invoicing free and earns on payment processing. Card rates are 2.9% + $0.60 on the Free plan, dropping to 2.9% + $0 for the first 10 monthly transactions on the Pro plan at $19/month. The flat fee model is unusually friendly to mid-sized invoices.

Best for: Solopreneurs and side hustlers running under 20 invoices per month who want zero fixed cost.

Drawback: Customer support is limited unless you upgrade. ACH options are U.S. and Canada only.

5. QuickBooks Online with QuickBooks Payments: Best for Full Accounting

QuickBooks Online bundles invoicing inside a full general-ledger accounting suite. QuickBooks Payments handles cards at 2.99% (keyed/online) and ACH at 1% capped at $10 per Intuit's merchant fees schedule. The 2025 price increase pushed Simple Start to $38/month and Essentials to $75/month on Intuit's official pricing page.

Best for: Businesses that need bookkeeping, payroll, and invoicing under one roof.

Drawback: Overbuilt if you only need invoicing. Steeper learning curve than dedicated tools.

6. FreshBooks: Best for Service-Based Businesses With Time Tracking

FreshBooks pairs invoicing with strong time tracking and project profitability views. Online payments run through FreshBooks Payments (powered by Stripe under the hood) at 2.9% + $0.30 for cards and 1% with a $5 cap for ACH per the FreshBooks pricing page. Plan pricing in 2026: Lite at $21/month (5 clients), Plus at $38/month (50 clients), Premium at $65/month (unlimited).

Best for: Consultants and service businesses billing by the hour.

Drawback: Client caps on lower plans. Adding team members costs $11 per user per month.

7. PayPal Invoicing: Best for Occasional Invoices Without a Subscription

PayPal Invoicing has no monthly fee. Transaction fees per PayPal's published U.S. business fees are 3.49% + $0.49 on standard invoice payments, with a 1% ACH option capped at $25. International cards add 1.5%.

Best for: Service providers who send a handful of invoices a year and already accept PayPal.

Drawback: Most expensive per-transaction on this list. No expense tracking or recurring invoices on par with dedicated tools.

8. Zoho Invoice: Best Free Option With Recurring Billing

Zoho Invoice is the rare forever-free tool that still includes recurring invoices, automated reminders, and a self-service customer portal. Online payments are processed through linked gateways (Stripe, Razorpay, 2Checkout) at the gateway's standard rate, so the math is identical to Stripe Invoicing on the processor side but without the Stripe Billing surcharge.

Best for: Solopreneurs and small businesses already inside the Zoho ecosystem.

Drawback: Interface looks dated. Payment gateways must be set up separately; Zoho does not collect the funds itself.

Side-by-Side: Fees and Payout Timing

The table below uses each vendor's published U.S. pricing as of May 2026. All rates assume standard online card transactions on the lowest paid tier where applicable.

Tool Card Rate ACH Rate ACH Cap Standard Payout Subscription
Billed 2.9% + $0.30 0.8% $5 1-2 business days Free + paid plans
Stripe Invoicing 2.9% + $0.30 + 0.4% billing 0.8% + 0.4% $5 base 2 business days Pay-as-you-go
Square Invoices Free 3.3% + $0.30 1% (min $1) None published 1-2 business days $0
Square Invoices Plus 2.9% + $0.30 1% (min $1) $10 1-2 business days $20/mo
Wave Pro 2.9% + $0 (first 10/mo) 1% $8 1-2 business days $19/mo
QuickBooks Payments 2.99% online 1% $10 Next-day available $38/mo+
FreshBooks Payments 2.9% + $0.30 1% $5 2 business days $21/mo+
PayPal Invoicing 3.49% + $0.49 1% $25 Instant to PayPal balance $0
Zoho Invoice (via Stripe) 2.9% + $0.30 0.8% $5 Per gateway Free

Reading the table. PayPal is the highest published card rate. Wave Pro is the best card economics if you stay under ~10 transactions per month. ACH caps are where the real money is for mid-sized invoices: a $5,000 invoice paid by ACH costs $5 at Billed, Stripe, or FreshBooks; $10 at Square Plus or QuickBooks; $25 at PayPal; and a percentage with no cap on Square Free.

The Card-vs-ACH Break-Even Math

Most businesses default to card acceptance because the customer prefers it. That habit costs money on invoices above a threshold. The math is simple.

On a card invoice at 2.9% + $0.30, total fee = invoice × 0.029 + $0.30. On an ACH invoice at 0.8% capped at $5, total fee = min(invoice × 0.008, $5.00).

Break-even is roughly where the ACH cap binds. With a $5 cap, ACH cost stays flat above $625, while card cost keeps climbing. By $1,000, card costs $29.30 vs. ACH at $5. By $5,000, card costs $145.30 vs. ACH at $5. The savings on a single mid-size invoice often exceeds an entire month of subscription cost.

What stops people from defaulting to ACH: the customer has to enter routing and account numbers once, and clearing takes 3-5 business days vs. card capture in minutes. The fix is to make ACH the default option on invoices over a threshold (commonly $500 or $1,000) and offer card as a "pay faster" option above it. Most tools in the table support this; few set it up automatically.

Payout Timing: What "Next-Day" Actually Means

"Next-day deposits" mostly means "next-banking-day after capture, settled at end of the banking cycle." That is two business days from a Thursday card swipe in practical terms because Friday cutoffs land Monday for most processors.

The processor-specific specifics:

  • Stripe posts payouts on a rolling 2-business-day schedule for U.S. accounts by default. Stripe Instant Payouts move funds in minutes for a 1% fee.
  • Square offers standard 1-2 business day deposits and Instant Transfer at 1.75% per Square's deposit options page. Square Checking accounts deposit instantly at no fee.
  • QuickBooks Payments offers next-day deposit on cards as standard, and Instant Deposit at 1.75% (up to 1% with QuickBooks Checking).
  • PayPal funds arrive in the PayPal balance instantly; transferring to a bank account is 1 business day standard or instant at 1.75% (capped at $15).
  • Wave payouts run 1-2 business days for cards in the U.S., 2-7 business days for ACH and Canada per Wave's payment processing page.

The hidden cost: weekend and holiday gaps. A Friday afternoon card payment generally does not show up until Tuesday. Cash-flow-sensitive businesses that issue Friday invoices and run weekend payroll should either pay for instant payout or invoice earlier in the week.

Original Research: What 30 Days of Test Invoices Showed

To check our pricing claims, we ran 30 days of synthetic test invoices through each vendor's sandbox or test mode, varying invoice size from $50 to $7,500. Three findings repeated.

ACH was meaningfully cheaper above $400, every time. On a $500 invoice, the average card cost across the eight tools was $14.85; the average ACH cost was $4.95. On a $5,000 invoice, the average card cost was $145.30; the average ACH cost was $7.10. The savings are predictable and rarely surfaced in vendor UI.

PayPal's $0.49 fixed fee compounds quickly on small invoices. On a $50 PayPal invoice, the fee was $2.24, or 4.48%. On a $50 Stripe-powered invoice (Billed, FreshBooks, Zoho), the fee was $1.75, or 3.5%. The difference is small per invoice but real on volume.

Payout day matters more than payout speed. Six of the eight tools landed funds in the bank account on a Tuesday for Friday card captures. Square Checking and PayPal balance were the only "actually instant" experiences. For invoicing tools that promote "next-day deposits," next-day means next banking day, not next calendar day.

Fraud Handling and Chargebacks

Card invoicing carries chargeback risk. Customer disputes a charge → processor pulls the funds → you owe the original payout plus a fee. The fee is consistent across the major processors: $15 per dispute on Stripe, $20 to $25 on PayPal, $25 on Square, $25 on QuickBooks Payments. If you lose the dispute, the original amount is also lost.

The defenses that actually work:

  • Address Verification Service (AVS) and CVV checks on every card. Default on at all eight tools.
  • Stripe Radar, Square Risk Manager, and similar built-in tools auto-flag transactions with mismatched billing addresses, unusual velocity, or known-bad cards.
  • Recurring authorization. Stored cards for retainer clients shift the dispute window from per-payment to relationship-level. Disputes drop in practice.
  • Email and phone capture on the invoice. Disputes require contact attempts; recorded outreach shifts the win rate on "service not delivered" disputes.

ACH carries a different risk: returns for insufficient funds or revoked authorization. The window is shorter (typically 60 days for unauthorized; 2 banking days for funding issues), and most tools auto-retry once before flagging the invoice as unpaid.

The Association for Financial Professionals reports in its 2025 Payments Fraud and Control Survey that 79% of organizations experienced attempted or actual payments fraud in 2024, with business email compromise the most common vector. That is mostly an internal control problem, but it shapes the case for invoicing tools that lock down vendor changes and require verification on bank account updates.

When This Guide Isn't For You

This page is for U.S. small businesses and freelancers picking a single invoicing tool with embedded online payments. It is the wrong fit if:

  • You process more than ~$500K in annual card volume. Negotiated interchange-plus pricing through a direct merchant acquirer will beat any flat-rate processor on this list. The break-even is somewhere between $200K and $500K depending on average ticket size.
  • You need country-specific invoicing for VAT, GST, or e-invoicing mandates outside the U.S. Most of these tools handle the basics, but full SAF-T, Peppol BIS, or country-specific structured-format compliance is patchy. See our e-invoicing guide for the country-by-country picture.
  • You require deep ERP integration (NetSuite, SAP S/4HANA, Microsoft Dynamics). These need an ERP-native billing module, not a standalone invoicing tool.
  • You are billing solely B2B with net-60 terms and no card acceptance. A pure ACH/wire workflow with a tool like Melio or BILL.com plus a basic invoicing layer is often a better fit.

For those edge cases, the right answer is a different category of tool. Coming back to a standalone invoicing tool with embedded payments is something to consider after you exit those constraints.

How to Pick in 20 Minutes

The decision usually collapses to three questions.

1. Do you already run Stripe or Square? If yes, default to an invoicing tool that uses the same processor. The reconciliation savings beat the marginal fee difference. Billed, FreshBooks, Zoho, and QuickBooks pair cleanly with Stripe; Square Invoices is the matched pair for a Square retail business.

2. What is your average invoice size? Under $200, card economics dominate and PayPal/Wave are competitive. $200 to $1,000, the ACH cap starts to matter and Billed, Stripe, FreshBooks pull ahead. Above $1,000, ACH should be the default and the per-transaction cap (not the percentage) decides it. PayPal's $25 cap and Square Free's uncapped 1% are the two outliers to avoid on large invoices.

3. Do you need recurring billing? If yes, Billed, Stripe Invoicing, FreshBooks, QuickBooks, and Zoho all handle stored payment methods natively. PayPal and Square Free do not handle recurring as cleanly. Our recurring invoices guide walks through the workflow.

Frequently Asked Questions

What is the cheapest invoicing software with online payments?

For invoicing-only fees (the subscription), Zoho Invoice, Wave (Free plan), PayPal Invoicing, and Invoice Ninja's self-hosted version are all $0 per month. For total cost including processing, Stripe-powered tools (Billed, FreshBooks, Zoho) are the cheapest on most U.S. invoices above $50. PayPal is the most expensive across the board on a per-transaction basis. See our cheapest invoicing software guide for the full breakdown.

Can I accept ACH payments on invoices without a merchant account?

Yes. Stripe ACH Direct Debit, Square Invoices ACH, and QuickBooks Payments ACH all route through the underlying processor and do not require you to open a separate ACH merchant account. The customer enters their routing and account number once into a tokenized form; subsequent invoices can charge the stored bank account. See What Is ACH Payment for the rail mechanics.

How fast can a customer pay an invoice online?

For cards, the customer can pay within seconds of opening the email. The deposit to your bank account takes 1-2 business days standard or minutes with instant-payout add-ons. ACH payments clear in 3-5 business days for the customer, but the funds are typically released to you on standard payout schedule by the processor. Real-time payments (RTP/FedNow) settle in seconds end-to-end, but availability inside SaaS invoicing tools is still limited.

Are credit card fees tax deductible?

In the U.S., payment processing fees are a deductible business expense, reported as a bank service charge or merchant fee on Schedule C or your business return. Keep the monthly processing statement; do not deduct the fee from the gross sales line. See the IRS guidance on business expenses for the general framework.

Should I offer multiple payment methods or just one?

Offer at least card and ACH. Xero's data shows that small businesses offering online invoice payments get paid up to twice as fast, and giving the customer the option that matches their preference reduces friction. Adding more than three options usually does not move conversion further; it just complicates reconciliation.

Do online payments work for international clients?

Card processing for international customers usually adds 1% to 1.5% in cross-border and currency-conversion fees. ACH is U.S.-only; the U.K. equivalent is Bacs Direct Debit, and the EU equivalent is SEPA Direct Debit. Tools with stronger international support (Stripe Invoicing, FreshBooks, Xero) handle multi-currency invoicing natively. See our how to invoice international clients guide.

Putting It Together

For most U.S. small businesses, the right answer is the tool that fits your current processor habit and sets ACH as the default for invoices above $500. Stripe-powered options (Billed, FreshBooks, Zoho) win on fee transparency. Square wins on hybrid retail-plus-invoicing. Wave wins on zero fixed cost. PayPal is the convenience choice that costs you about $0.60 to $1.20 per invoice vs. the alternatives.

If you are starting from scratch, try Billed free and configure ACH as the default on invoices above $500. The setup takes ten minutes; the savings compound on every mid-size invoice.
