Streamline Business Payments: The Ultimate Guide to Accounts Receivable Conversion (ARC)

In today's fast-paced business environment, paper checks remain surprisingly persistent despite their inefficiency. Processing physical checks costs businesses significant time and money—according to NACHA, paper check processing can cost 3-5 times more than electronic payments. Enter Accounts Receivable Conversion (ARC), a transformative solution that bridges the gap between traditional check payments and modern electronic processing. This guide explores how ARC leverages the Automated Clearing House (ACH) network to convert paper checks into electronic transactions, revolutionizing how businesses handle receivables.

Why this matters:
Businesses adopting ARC typically reduce payment processing costs by 60-80% while accelerating funds availability from days to hours—a critical advantage in cash flow management.

1. What Is Accounts Receivable Conversion (ARC)?#

Accounts Receivable Conversion (ARC) is a payment processing technology that electronically converts paper checks received as payment for goods or services into ACH transactions. Specifically designed for business-to-customer (B2C) and business-to-business (B2B) receivables, ARC eliminates the physical handling of checks by:

  • Capturing check details via scanning
  • Creating an electronic debit entry
  • Processing payment through the Automated Clearing House network

Key distinction: ARC applies exclusively to checks received for existing accounts receivable, not point-of-sale transactions. This makes it ideal for invoice payments, recurring billing, and mailed payments.

2. How ARC Works: From Paper Check to Electronic Payment#

The conversion process involves four streamlined steps:

  1. Check Receipt & Endorsement

    • Customers mail paper checks to the business as payment
    • Checks are endorsed with "For ARC Conversion Only" to authorize processing

  2. Check Scanning & Data Capture

    • Checks are scanned using specialized hardware/software
    • Critical data is extracted: routing number, account number, check amount

  3. ACH File Creation

    • Scanned data generates an ACH Standard Entry Class (SEC) file
    • SEC code used: ARC (designating accounts receivable conversion)

  4. Settlement & Archiving

    • ACH network debits payer's account and credits receiver's account
    • Original checks are securely stored for 2 weeks (per Regulation CC) then destroyed

Critical timeline: Funds typically appear in the business account within 1-2 business days vs. 3-5 days with traditional check processing.

3. Key Benefits of Implementing ARC#

🚀 Cost Reduction#

  • Eliminate manual processing costs: Save 1.00−1.00-3.00 per check in labor, deposit prep, and transportation
  • Reduce bank fees: ARC transaction fees are typically 60% lower than check processing fees

💨 Accelerated Cash Flow#

  • Faster funds availability (next-day settlement common)
  • Reduced risk of payment delays due to mail transit or human error

📈 Operational Efficiency#

  • Automate reconciliation through digital records
  • Integrate with accounting software (e.g., QuickBooks, Xero)
  • Free staff from manual data entry and bank runs

🌿 Environmental Impact#

  • Decreases paper waste
  • Lowers carbon footprint from transportation

4. The Role of ACH in Accounts Receivable Conversion#

The Automated Clearing House (ACH) network is the backbone of ARC transactions. Key features:

ACH CharacteristicImpact on ARC
Batch ProcessingAllows bundled processing of converted checks
NACHA ComplianceGoverns data security, authorization, and record retention
Same-Day ACH OptionEnables 2 settlement windows daily for urgent payments
Universal StandardsEnsures interoperability between all U.S. financial institutions

Authorization requirements: Businesses must display ARC conversion notifications on invoices or through separate written agreements to comply with NACHA rules.

5. Getting Started with ARC: Implementation Guide#

🔧 Prerequisites#

  • Business checking account with ACH capabilities
  • NACHA compliance certification
  • Check scanning hardware/software

⚙️ Implementation Steps#

  1. Bank Partner Selection
    Choose a financial institution or payment processor supporting ARC services.

  2. System Integration
    Connect ARC software with accounting systems via API or middleware.

  3. Authorization Setup
    Add legally required disclosures to invoices:
    "By submitting a check, you authorize us to process payment electronically via ACH."

  4. Staff Training
    Train teams on check endorsement protocols, scanning procedures, and reconciliation.

  5. Go-Live Testing
    Process test checks before full deployment.

Cost considerations: Expect setup fees of 200−200-500 plus per-transaction fees of 0.10−0.10-0.30.

6. Security and Compliance Considerations#

  • Regulation CC: Mandates 2-week physical check retention
  • NACHA Rules: Requires written authorization for conversions
  • Data Security: ENCRYPT check images and ACH files during transmission/storage
  • Fraud Prevention: Use Positive Pay services to match checks against issued payments

Audit Tip: Maintain conversion logs showing customer authorization dates for 3 years.

7. Conclusion: Is ARC Right for Your Business?#

ARC delivers transformative value for businesses receiving over 100 checks monthly. It's particularly advantageous for:

  • Utilities companies
  • Insurance providers
  • Property management firms
  • Healthcare billing departments
  • Any business processing recurring/receivable payments

Signs you need ARC:
If your team spends >10 hours/week processing checks, or if payment delays regularly impact cash flow, adopting ARC could yield >100% ROI in the first year through cost savings and improved liquidity.
