Payment Processing

Payment Processing

The system and services that facilitate the transfer of money from a payer (client) to a payee (business) for invoice settlement, including credit/debit card networks, ACH bank transfers, and digital payment platforms.

Updated June 9, 2026

TL;DR

Payment processing is the infrastructure behind how clients pay your invoices — from credit card swipes to ACH bank transfers to Stripe or PayPal. The method affects how fast you get paid, what you pay in fees, and how easy the experience is for your client.

Key Points

Payment processing fees vary by method: credit cards typically 2.9% + $0.30 per transaction; ACH is usually $0.25–$1.50 flat per transfer

Faster payment methods (credit card, instant ACH) reduce [[days-sales-outstanding]] but cost more; slower methods (standard ACH, check) are cheaper but slower

Offering online payment links in your [[invoice]] reduces friction and speeds collection significantly

Different clients prefer different methods — offering multiple options maximizes your chance of fast payment

Common Payment Methods for Invoices

For B2B invoicing, the most common payment methods are: ACH bank transfer (also called direct debit or EFT) — funds transfer electronically from the client's bank account to yours. Standard ACH takes 1–3 business days; same-day ACH is available for a higher fee. Credit/debit card — faster (funds typically settle within 1–2 business days) but subject to higher processing fees (2.9%+). Wire transfer — immediate clearing for large amounts but expensive for both parties ($20–$50 per wire). Digital wallets (PayPal, Stripe, etc.) — user-friendly, moderate fees. Check — traditional, zero processing fee for you, but slow (mailing + clearing time) and requires manual deposit1.

Payment Processing Fees

Understanding payment processing costs is essential for pricing. Credit card fees (via Stripe, Square, etc.) are typically 2.9% + $0.30 per transaction. On a $5,000 invoice, that's $145.30 in fees. ACH/bank transfer fees are typically flat — $0.25 to $1.50 per transaction, making them far cheaper for large invoices. Some businesses pass processing fees to the client via a 'convenience fee' or credit card surcharge — legal in most US states but worth disclosing clearly in your Contract to avoid disputes. Others absorb the fee as a cost of doing business. For large invoices, ACH is almost always preferable on cost; for smaller amounts or international clients, card is often more practical.

Choosing the Right Payment Infrastructure

For most freelancers and small businesses, a payment-enabled invoicing platform — like LiteBill — is the simplest approach. These platforms integrate payment processing directly into the invoice, letting clients click 'Pay Now' and settle via card or ACH in minutes. This dramatically reduces payment friction and improves DSO. When evaluating options, consider: processing fees, deposit speed (how quickly funds arrive in your account), payout minimums and schedules, multi-currency support if you have international clients, and whether the platform integrates with your accounting software for automatic reconciliation. A platform that costs 0.3% more per transaction but reliably cuts your average payment time from 45 days to 12 days is almost always worth the difference.
