In order to give full access to all the calculations possible in inventory modules, we have added a set of auto-calculated fields with all the values. These fields will permit easier advanced reporting both inside and outside of the application.

Additionally, we have added support for special tax types which are summed up separately in order to simplify or make possible some common tributation configurations present in many countries.

The fields have all been added to a new block called “Financial Information” and they are:

• Gross total: the sum of all line totals with no discounts nor individual taxes
• Line discount: the sum of all individual line discounts
• Global discount: the value of the global discount applied in the footer of the record
• Total discount: the sum of line and global discount
• Net before global discount: gross total minus individual line discounts
• Net total (after global discount): gross total minus total discounts
• Tax retention: the sum of all taxes marked as type retention
• Total tax: the sum of all taxes applied
• Shipping and handling total: a copy of the value in the footer
• Shipping and handling tax: the sum of taxes applied to shipping and handling
• Adjustment: a copy of the value in the footer
• Grand total: a copy of the value in the footer

In a more mathematical notation, it would be

• gross = ∑linetotals
• line_discount =∑line_discounts
• total_discount = lined_discount + global_discount
• net = gross - total_discount
• total_tax = ∑line_taxes + group_tax
• grand_total = net + total_tax + s&h + s&h_tax + adjustment

The retention tax type can be established in the tax settings page and is simply to sum them separately.

This section is intended to signify the meaning of InventoryDetails fields. Since there are four main inventory modules, each field should receive a separate meaning for each 'context' (the inventory module the record belongs to). When the meaning is similar in all contexts, only one will be provided.

Quotes This field has no meaning SalesOrder This field signifies whether all units of the line have been delivered. When no units have been delivered or a part of the sold units (field: Quantity) have been delivered, this field should remain unchecked.

Only when all sold units have been delivered to the Organization this field should be set to 'yes' Invoice This field has no meaning PurchaseOrder This field signifies whether all units ordered at the vendor (Quantity field) have been received by us. As long as there are more units in the Quantity-field than in the 'Delivered/Received' field, this field should remain unchecked

When the no. in 'Units Delivered / Received' meets or exceeds the no. in 'Quantity', this field should be set to 'yes'.

Quotes, SalesOrder, Invoice This field indicates the costprice of the product or service, per unit PurchaseOrder This field should be zero. The costprice of a product should, in the context of a purchaseorder, be represented on the 'Unit Price' field.

All This field should carry the value of the stocklevel of the related product of the line at the moment the line was created and the master-record was first saved. After the initial save, this field should never be altered.

The stock we use to fill in this field will respect the units delivered/received field as such: when a master-record (like SalesOrders) ‘delivers’ units, the stock saved on this field will reflect the stock on the product, minus the units delivered on the first save. When a master-record receives products (like PurchaseOrders), the field will hold the product stock plus the units received at the first save.

Subsequent changes to the units delivered/received field will not update this field.

Quotes No meaning SalesOrder The number of units that remain to be delivered to the Organization. Should always be the 'Quantity' minus the 'Units Delivered/Received'. Invoice No meaning PurchaseOrder The number of units that remain to be received from the vendor. Should always be the 'Quantity' minus the 'Units Delivered/Received'.

Quotes Which product/service are we offering? SalesOrder Which product/service are we selling? Invoice Which product/service are we invoicing? PurchaseOrder Which product/service are we buying?

Quotes B2C: Empty, or the company the contact works in B2B: To whom are we offering the product or service SalesOrder B2C: Empty, or the company the contact works in B2B: To whom are we selling the product or service Invoice B2C: Empty, or the company the contact works in B2B: To whom are we invoicing the product or service PurchaseOrder No meaning, should be empty

All If the Product field contains a Product (not a service), the main vendor of that product PurchaseOrder Concept: not in production: From whom are we buying the product or service?

All A reference to the legacy 'productinventoryrel' table ID

Quotes, SalesOrder, Invoice The unitprice of the Product of Service on the Product-field PurchaseOrder The Costprice of the Product of Service on the Product-field

All The total amount of money this line represents, before discounts or individual taxes. The formula would be

Quantity * Unit Price

Quotes, SalesOrder, Invoice The discount awarded to the Organization for this particular line, represented as an absolute amount of money.

When there is a direct discount awarded to this line, that amount will be placed here directly.

When there is a discount percentage awarded to this line, the amount represented by that percentage will be calculated and automatically filled in here. PurchaseOrder The discount awarded by the Vendor to us for this particular line, represented as an absolute amount of money. An administration department should later verify that this discount was actually deducted when we receive the Invoice.

When there is a direct discount awarded to this line, that amount will be placed here directly.

When there is a discount percentage awarded to this line, the amount represented by that percentage will be calculated and automatically filled in here.

All A quantified representation of the sum of all tax percentages. This follows the formula:

Net Total * (Tax Percent / 100).

The Net Total and the Line Tax together form the Line Total

Quotes No meaning SalesOrder The number of units that have been delivered to the Organization. Invoice No meaning PurchaseOrder The number of units that have been received from the vendor.

Quotes, SalesOrder, Invoice The total costprice of this line, represented as an amount of money. This follows the formula:

Cost Price * Quantity PurchaseOrder This field should always be zero

This field needs to be discussed. What I don't like is that it is Uitype 1. Not only is this the wrong Uitype for an ID (should be 7 since it's always a number), it's also not a reference field. So if we decide to give some meaning to this field, we won't be able to use workflows on it. Context Purpose Quotes No meaning, should be empty SalesOrder References the InventoryDetails line on which this line was offered. So the context of the line referenced is a Quote Invoice References the InventoryDetails line on which this line was sold. So the context of the referenced line is a SalesOrder. There could be multiple Invoicelines referencing a single SalesOrderline, since a SalesOrder could be Invoiced in multiple tranches PurchaseOrder References a possible InventoryDetails line on which this product was sold. Only applicable when there is a direct and true relationship between these lines. Meaning: a product sold to an Organization on a SalesOrder is ordered at a Vendor in the same Quantity.

Note: there could be 'collector' lines for PurchaseOrders, e.g.: PurchaseOrder lines that order Products in one line that are meant to fulfill multiple SalesOrderlines. This can, in this configuration only be done by relating those records on a M:M basis.
