Help createing Inventory Volume report
I've been working with Zoho support for a few months now trying to develop a inventory volume report. Though they have been helpful, it never seems to generate exactly what we're looking for. I thought I'd turn to the community for further help. We've been approaching this via Zoho Inventory and Zoho Analytics to generate the actual report.
In the most basic form we're looking to generate the average volume in our warehouse by client on a monthly basis to determine storage billing.
——————
Monthly storage volume billing calculation
1cu ft: 12in x 12in x 12in = 1728
Volume: (Package H x W x D) / 1cu ft
Avg Monthly Volume: Volume * Average Daily Qty/Stock
Pallet space: 52.8 cu ft
Storage Cost: =CEILING(Avg Monthly Volume/pallet space) * $30

How this would translate to our use case

The above formula is pretty straight forward but what doesn't seem possible is capturing/accessing the stock on hand for each day in a given time frame (as we plan to use a date range filter in our report)
Again, basic math/formula, but how we would determine the average stock for an entire month
Working with Zoho support they have helped with custom queries and pivot tables but the stock on hand seems tightly correlated to Stock In Flow, Stock Out Flow, Sales and Invoices. Though Stock on Hand has to do with Stock In/Out Flow, Sales/Invoices, isn't there a way to disregard these aspects and just focus on Stock on Hand? ie if a client inquired about how many of a certain product is in our warehouse that day, we can easily go into a product and get Stock on Hand.
Hoping another set of eyes or thinking can help here.
Thanks!
