Microsoft Excel

I need a consolidated budget workbook for the quarterly financial review showing actuals versus forecast across operations, events, and grounds for Q2 to date. Pull the monthly ledgers, map the GL codes to the budget lines we agreed with Finance, calculate variance percentages, and produce a printable summary page for the finance director by Wednesday afternoon.

Before I send this workbook to the finance director, make the spreadsheet easy to use: put totals and the variance percent for each section at the top, make the month-to-month figures easy to trace to the source ledger rows, flag any GL mappings that were assumed or uncertain, and add a one-line instruction for the reviewer on where to check the source entries.

I reconciled the Q2 workbook to the ERP extract and found a $4,200 difference concentrated in event catering expense for May. I can't tell if I mis-mapped GL codes, missed an accrual, or the ERP extract is incomplete. What's the most likely cause and the best next action so I can fix it before the review on Wednesday?

Each quarter we scramble to rebuild the consolidated budget workbook, wasting analysts' time and producing last-minute errors. I want to change one habitual behavior so the workbook is reliable with two days' lead time. What standardization, naming convention, or small automation habit will get us there?
