Hey everyone, looking for advice from recruiters, HR, or accounting pros on how to handle a job title mismatch on my resume and LinkedIn.  
In October 2025, I was brought on through a staffing agency to work at a company during a corporate acquisition. On the agency's internal payroll system, my official title was coded as "AR Clerk." However, I have literally never done AR work in this role. From my very first day up until now, my actual scope has been Accounts Payable Specialist / Accounting Specialist work alongside broader core accounting duties, managing full-cycle AP operations, assisting with general ledger cleanup, handling vendor communication, and supporting month-end close procedures.  
I'm looking to transition to my next role and want to make sure I present this correctly without hurting my chances or causing issues later. A few specific questions:

Resume Title: Can I put "Accounts Payable Specialist" (or even "Accounting Specialist" given the GL cleanup and month-end close scope) as my primary title? Listing "AR Clerk" feels completely misleading to recruiters since it doesn't reflect my actual daily duties or skillset.

Background Checks: When a future employer runs a background check, the agency will verify my payroll title as "AR Clerk." What is the best way to format this on a resume so it doesn't trigger a discrepancy flag? I would also be able to get references for what I did.

Avoid Confusion: I thought about writing "Accounts Payable Specialist / AR Clerk," but I've heard slash titles combining AP and AR look confusing and contradictory since they are separate accounting functions. How would you format this on a resume and LinkedIn to get credit for the actual AP, GL cleanup, and month-end close work performed while keeping background checks clean?

Agency title is "AR Clerk", but I've been doing AP Specialist work, GL cleanup, & month-end close since day 1. How do I list this on my resume?
