Asset Register PRO for Excel supplies nine asset registers plus YTD depreciation reports for fixed, intangible and investment assets, updating and reporting depreciation calculations and book values at each month end. Each asset entered into the register can contain the asset sequence number, date of purchase, description of asset, serial number, supplier's name, purchase order number, G/L reference code, accounting cost, useful life (depreciation period), physical location, plus if/when disposed/sold and gain/loss calculations and impairment ledgers for investments, intangibles and goodwill. Asset Register PRO can be used by the smallest to the largest enterprise to keep track of their assets and monthly depreciation calculations. Asset Register PRO applies the straight-line depreciation method, and the declining balance method adjusted annually and monthly. Depreciation tables supply monthly depreciation and cumulative depreciation from the acquired date to any period up to 240 months. Quick and easy entry of assets into the registers using Excel's Data (Entry) > Form with the Name box. Asset Register PRO provides continuous month end sequencing so that the asset class registers update each asset depreciation and book value every month automatically and combines all month end values into a Year To Date and Totals report. Different depreciation periods can be applied to individual assets and within each class of assets. Asset Register PRO calculates book values at disposal dates and gain/losses on disposal. All month end depreciation calculations and book balances can be recalculated backwards and forwards to any month end date by making a simple one step adjustment to the month end date held in the adate field. You can recalculate and forecast depreciation totals and written down balances for any month end past or future. Such calculations can be very useful for preparing financial business forecasts and for checking depreciation calculations.

Pivot4U Add-in enhances Microsoft Excel with a new useful feature - editable pivot tables. A pivot table is a data summarization tool that, among other functions, can automatically sort, count, and total the flat data stored in one table or spreadsheet and create a second table displaying the summarized data. For all its advantages, Excel has some limitations. One of them is the missing ability to change the data directly in the data area of a pivot table. The pivot table is linked to the source data, and what you see in the cells of the table are read-only values. But with Pivot4U in place, you can go beyond this limitation and make your pivot table editable.

Let's say, for example, you have a spreadsheet with the plan of sales for some products. The spreadsheet is named "SourceData" and it has the following fields: Region, Color, Month, Sales. You want to change some values in the pivot table generated from the data in this sheet. With Pivot4U, this operation is a breeze to do. Create a pivot table from the data in the "SourceData" sheet, go to the "Add-Ins" tab of Microsoft Excel, select "Pivot4U On" and set the cursor on any cell in the pivot table. Now you can change the value in the cells directly from, say "650" to "830". When the value is changed, all totals are recalculated automatically.

With Pivot4U Add-in in place, all the power of calculations and planning "FROM ABOVE-DOWNWARD" becomes accessible without complex and costly software.
