Detail costs and expenses for services or projects

I need a clean cost breakdown for the consulting engagement with Horizon Water through June. Build a single worksheet that lists each invoice line, vendor, date, billable category, and whether it is fixed fee or time-and-materials, with totals by category and a final column that flags any line older than 60 days. I will review before submission to finance on Thursday.

Before I send this to procurement, make the cost sheet obvious to a skeptical reviewer: put the total project cost and the month-to-month burn in the top-left, show savings or discounts next to each vendor line, hide raw hourly rates but make effective hourly cost findable, and highlight any assumptions that would make a budget owner hesitate (scope creep, travel, subcontractor markups).

I have one worksheet of billed lines and another of bank payments; Muna says the project total is off by about four thousand. I don't know whether I mis-categorised transactions, missed credits, or broke a formula linking the bank sheet to the cost sheet. What's the most likely cause and the single best next check I should run before escalating?

Each month we lose time reconciling vendor invoices with bank payments and often miss credits or duplicate charges. Where am I most likely wasting effort—data entry, inconsistent vendor naming, or fragile formulas—and what one habit change will cut reconciliation time and reduce missed credits starting next month?
