The Institute of Finance & Management (IOFM) offers two primary certifications for Accounts Receivable professionals:

• Accounts Receivable Specialist (ARS) – designed for professionals responsible for executing AR processes and daily operations
• Accredited Receivables Manager (ARM) – designed for those in supervisory or management roles overseeing AR teams and functions 

These certification programs focus on building expertise in key areas such as credit management, billing, collections, cash application, reporting, compliance, internal controls, and process improvement. They also emphasize adapting to automation, regulatory requirements, and evolving financial operations. 

Both certifications typically include structured training and require passing a final exam to earn the credential. 

Earning an IOFM AR certification demonstrates a high level of knowledge in receivables management and supports career growth by validating skills needed to manage processes, improve efficiency, and contribute to organizational cash flow performance. 

An AR resume should show proof of billing, collections, cash application, reconciliation, reporting, audit support, dispute resolution, and customer account ownership. Strong examples include allocating incoming payments, issuing SAP billing, reconciling customer accounts, processing offsets and refunds, applying payments accurately, resolving customer disputes, preparing AR reports, supporting audits, managing chargebacks, improving billing and collections efficiency, and overseeing teams or portfolios.

Leadership signals appear through team development, policy enforcement, schedule and workload management, performance reviews, training, process automation, internal controls, strategic productivity reviews, and managing an AR portfolio up to $40M.

An effective Accounts Receivable cover letter should clearly show your ability to manage billing, payments, and financial accuracy while supporting business cash flow. It typically follows a structured format—introduction, body, and closing—where you connect your experience to key AR tasks like invoicing, reconciliation, collections, and dispute resolution.

Focus on demonstrating real impact, such as improving processes or reducing outstanding balances, while maintaining a professional and concise tone. Rather than repeating your resume, use the letter to highlight your value, align with the company’s needs, and reinforce your contribution to financial performance.

Accounts Receivable (AR) Professionals protect cash flow, financial accuracy, customer account integrity, and receivables performance by connecting billing, payment collection, reconciliation, reporting, controls, and process improvement across finance and business teams.
