ATALI ELECTRIC vs Excel templates and in-house models
ATALI ELECTRIC vs Excel templates for commercial tax appeals
Excel is the most capable general modeling tool a tax consultant owns, and a well-built in-house template is often the firm's real intellectual property. The cost shows up at volume: copies drift, inputs are retyped, and forms, binders and deadlines live outside the workbook. ATALI ELECTRIC applies the same logic to every parcel and still exports to Excel whenever you want the workbook.
What it is
Many consulting firms and owner tax departments run appeals out of Microsoft Excel: a master income template, a sales grid workbook, a uniformity tab per county and a deadline list, refined over years. Excel's formulas, Power Query data imports and data validation make it a capable modeling environment, and in Microsoft 365, workbooks stored in OneDrive or SharePoint support co-authoring and version history. Every hearing officer can read a printed Excel schedule.
| Dimension | ATALI ELECTRIC |  Excel templates and in-house models |
|---|---|---|
| Modeling flexibility | Configurable normalization rules and adjustment factors, with analyst overrides on every line | Unlimited: any formula or layout the analyst can build |
| Data entry | Notice OCR, rent roll and P&L import, and comparable uploads mapped to fields automatically | Typed or pasted, or imported with Power Query where someone has built the query |
| Consistency across parcels | The same rules run on every parcel, and exceptions are logged with a reason | Template copies drift as analysts edit them parcel by parcel |
| Formula integrity | Calculation logic maintained centrally; inputs validated before they reach the model | Hard-coded values, broken links and overwritten formulas can enter any copied workbook |
| Income approach | P&L and rent roll normalization with loaded cap rate, built in | As good as the template, which is often very good |
| Equity uniformity | Comparable assessments assembled and adjusted into a matrix with median adjusted value per sq ft | Comparable assessments gathered or imported, then arranged in a workbook tab |
| County forms | Official county forms filled from the parcel record | Typed into the county's form or online portal separately |
| Evidence binder | 20-page hearing-ready binder assembled automatically | Printed schedules collated with exhibits by hand |
| Deadline tracking | Filing windows, hearings, settlement offers and determinations tracked per parcel with alerts | A deadline sheet maintained by hand |
| Collaboration and access | Multi-user workspaces with role-based access control, MFA and per-tenant data isolation | Co-authoring and version history in Microsoft 365 when files live in OneDrive or SharePoint |
| Cost | From $499/mo billed annually, with Excel import and export included | Usually covered by the firm's existing Microsoft 365 licenses |
Choose Excel templates and in-house models when
- -You file a modest number of appeals and your templates already match what your local board expects to see.
- -You need a one-off model for an unusual property that no standard workflow fits.
- -A specialist on your team maintains the models and the team is small enough to coordinate versions by hand.
Choose ATALI ELECTRIC when
- Template drift has produced different answers for similar parcels, and you want one set of rules across the firm.
- Your analysts retype the same figures into notices, models, forms and binders.
- Busy season deadlines across many counties are tracked in a spreadsheet one person owns.
- You want Excel output on demand without Excel being the system of record.
Using both, or switching over
- Step 1
Import what your templates use
Rent rolls, operating statements and comparable lists come in as XLSX or CSV, so the inputs your templates already consume become the parcel record.
- Step 2
Run a past appeal in both
Rebuild a settled appeal in ATALI ELECTRIC and compare the indicated value with your template's answer. Differences usually trace to a normalization rule, which you can configure.
- Step 3
Export to Excel when you want the workbook
Income pro formas, sales grids and uniformity matrices export as XLSX for review, client delivery or a board that prefers spreadsheet exhibits.
- Step 4
Retire the deadline spreadsheet
Move filing windows, hearing dates and settlement offers into the Deadline Tracker so the calendar no longer depends on one workbook.
Questions
Can I export ATALI ELECTRIC schedules to Excel?
Yes. Every schedule, including the income pro forma, sales grid and uniformity matrix, exports as an XLSX file.
Will my existing templates still be useful?
Yes. They remain a good check during the transition, and their inputs (rent rolls, P&Ls, comp lists) import directly. Firms often configure ATALI ELECTRIC's normalization rules to match the conventions their templates encode.
Is ATALI ELECTRIC a Microsoft product or partner?
No. ATALI ELECTRIC reads and writes standard XLSX files and, with your administrator's consent, can work with workbooks stored in OneDrive or SharePoint through Microsoft Graph.
