Cost sheets are how the Due Diligence platform calculates the estimated repair and replacement costs for items inspected during your Unit Walks. This article covers what cost sheets are, the two types available (property-specific and business-wide), how to update them, and what happens after you submit.
Important: At this time, only the HappyCo Due Diligence Support team can apply updates to cost sheets and regenerate cost-related reports. Please submit your completed cost sheets via a Service Request, and we'll handle the upload from there.
What is a Cost Sheet?
A cost sheet is a CSV file that contains the dollar values applied to specific inspection items based on the condition (rating) assigned during the Unit Walk. When cost-related reports are generated, the platform pulls from the cost sheet to populate the values.
There are two types of cost sheets:
- Property Cost Sheets — specific to a single property, based on the inspection template assigned to that property
- Business-Wide Cost Sheets — apply across all inspection templates available to your business
When Are Costs Applied?
In most cases, costs should only be assigned to items with a Repair or Replace condition rating.
One common exception: if your team always removes carpet during turnover, it's okay to assign costs to Type items with Carpet, regardless of condition.
Property Cost Sheets
Property cost sheets are specific to a single property and contain only the inspection items from the template assigned to that property. They're ideal for one-off updates or property-specific pricing adjustments.
Before You Start
Reports must already have been generated for your Order — the property cost sheet only becomes available after reports have been created.

How to Update a Property Cost Sheet
- Go to the Google Drive where your reports are stored and download the file named
[PropertyName]_Cost_Sheet.csv. - Update the Cost column (Column F) with numbers only — no dollar signs ($), text, or special formatting.
- To "clear" a value, replace it with
0. ($0 costs will not appear in reporting.) - Save the file as a CSV (not Excel). Sorting and filtering during your edits is fine — just save in CSV format when you're done.
- Attach the updated cost sheet to a Service Request on your Order.

Important — Do Not Modify Columns A through E
Column A (ID) is the unique identifier the system uses to apply each cost to the correct section, item, and rating. If columns A–E are altered, the upload will not work correctly. Only edit Column F.
Business-Wide Cost Sheets
Business-wide cost sheets include all inspection templates available to your business. Updates made here automatically apply to all properties using those templates — so once business-wide costs are set, property-level edits should be minimal.
How to Request a Business-Wide Cost Sheet
The Due Diligence Support team must pull the business-wide cost sheet for you. To request one, submit a Service Request or email dd@happy.co.
How to Update a Business-Wide Cost Sheet
- Open the cost sheet provided by the Due Diligence Support team.
- Update the Cost column (Column F) with numbers only — no dollar signs ($), text, or special formatting.
- To "clear" a value, replace it with
0. ($0 costs will not appear in reporting.) - Save the file as a CSV. Sorting and filtering is fine.
- Send the updated file to dd@happy.co and we'll handle the upload and confirm once it's complete.
Best Practice
We recommend updating business-wide costs only once or twice per year. More frequent updates can become cumbersome to manage and may require additional coordination across reports.
Backfilling Past Projects
If you'd like updated business-wide costs to also apply to previous Due Diligence projects, just let us know when you submit your sheet — we're happy to apply the changes to past reporting as well.
What Happens After You Submit
Once your completed cost sheet has been submitted:
- The Due Diligence Support team will upload it on your behalf.
- We'll regenerate any cost-related reports tied to the update.
- You'll receive a confirmation that everything has been updated and reports are ready to view.
What's Coming Next
We're actively working on improvements to the cost sheet workflow to make it customer-facing in a future Due Diligence update. We don't have a specific release date to share at this time, but stay tuned — we'll let you know as soon as it's available!
