To send an invoice, the invoice must first be created in the Sales Invoices screen. This can be done manually, but in general invoices are collected. Transpas then checks which shipments are ready for invoicing and uses this to create one or more invoices according to the set invoice method. For example, an invoice can be created per day, week, period, shipment or file.
Invoices can be collected using the collection button in Transpas.
This button has the following icon: 
It sometimes happens that a shipment needs to be invoiced, but it cannot be selected during collection. Then it can be good to know which conditions must be met before a shipment or file can be collected, in order to check them one by one.
A shipment is collected on an invoice if the following conditions are met:
Collection date
When collecting, you will be asked to enter a Date to.
The date it works on is the collection date.
This is set per invoice group with the setting Shipments collection date.
The possible options are:
Consolidation
When a shipment falls within a consolidation, the consolidation must be prepared for invoicing.
All shipments within a consolidation are invoiced together.
Right-click on the shipment and select Jump to consolidation to check whether a shipment falls within a consolidation.
A booking is collected on an invoice if the following conditions are met:
An additional collection condition can be set per invoice group.
This can be done for bookings, shipments, sales lines and purchasing lines.
These settings are shown in the Companies screen on the Invoice groups tab.
The Collection condition field only applies to bookings, the other fields are self-explanatory.
The condition is applied during collection as follows:
WHERE ... AND ( {collection condition} )
Because there are round brackets around it, multiple conditions can be used, as well as an OR condition.
