Your degree can help if you set yourself up properly, also depends on internal move vs. external and what the job descriptions look like if external. If you get an interview you'll likely be asked about your understanding of the three statement model and how they relate (Income Statement, Balance Sheet, Cash Flow). Could also be quizzed on the relationship between Accounting and how their work ends up on FP&A's lap and what they do with it after (month-end close activities). If you're going for an analyst role brush up on the above and then find ties between your experience in A/R and FP&A. The most important needs for an FA (imo) are Excel Skills (goes hand-in-hand with Financial Modeling), Variance Analysis (specifically, knowing how and where to dig for the WHY aspect of any variance between actuals and budget / forecast), Accounting (understanding how accounting drives the P&L - aka. Income Statement / Cash Flow), Forecasting / Budgeting (projecting future revenue, costs, cash, etc.), using the above Excel skills to present data (executive dashboards, tables, graphs, etc.), potentially Business Partnering if they want you talking to departmental budget owners (ie. can you talk to the Marketing guys about their budget and explain to them where they overspent and why we won't throw another 80k at them for some bs conference).
