From the Plus package onwards, you can configure contributions per membership status. These settings apply to members who join online and when generating contribution invoices.
Per membership status, you can configure various preferences on the Contribution tab. Which options are available depends on the selected package and any additional modules.
Select Contribution Type
Congressus offers various membership fee options:
No membership fee
Personal membership fee
Collective membership fee (only for the 'Organizations' module + collective billing)
No contribution
If members with this membership status don't pay contribution, you can easily deactivate this feature. You can still charge a registration fee.
Personal contribution
🎯 Available for the Plus package and higher
You can configure several settings:
Contribution period - Set how often the membership fee is charged
Contribution product - Select the product used for the membership fee
Registration fee - This product is only used for new members who register through the website
Advanced settings
Depending on the selected package, the following advanced settings are available:
Term transition – used for new members; within the configured transition period, no invoice is created for the current term, but instead for the next contribution term
Pro rata – used for new members; the contribution for the current term is calculated based on the number of remaining days
Contribution invoice terms – you can configure additional contribution terms that members can choose from in their own profile
Multiple contribution products
From the Pro package onwards, you can set up multiple contribution products. Each product is added to the invoice separately.
Contribution products can have a filter. The product is only applied to members who match the configured filter.
Variable contribution
Variable contribution allows members with the relevant membership status to set a higher contribution amount through their own profile.
The amount entered by the member must be higher than the total amount of all configured contribution products.
We calculate the additional amount as follows:
Without a variable contribution product
On the invoice, we adjust the amount of the first contribution product. This amount is increased by the additional amount set by the member.
Please note: the additional amount is calculated automatically, it is the variable contribution amount entered in the member profile minus the total amount of all contribution products.
👉🏻 Example calculation – Three contribution products are set up (€100, €50, and €25). The member has €200 set in their profile. The contribution invoice will contain the following invoice lines:
Product 1 – €125 (200 − 100 − 50 − 25)
Product 2 – €50 (original amount)
Product 3 – €25 (original amount)
With a product for variable contribution
Optionally, you can select an alternative product that is used for the additional entered amount. In that case, the calculation is as follows:
👉🏻 Example calculation – Three contribution products are set up (€100, €50, and €25). Product 4 is set for variable contribution. The member has €200 contribution set in their profile. The contribution invoice will contain the following invoice lines:
Product 1 – €100
Product 2 – €50
Product 3 – €25
Product 4 – €25 (variable amount above the standard contribution) (200 − 100 − 50 − 25)
Collectieve contributie
🎯 Available for the Organizations module in combination with the Pro or Enterprise package
With collective contribution, it is possible to invoice the contribution not to the member themselves, but to an organization/employer. The settings differ in several respects from those for individual contributions.
You can configure various settings:
Contribution term – set how often the contribution is charged
Contribution product – choose the product used for the contribution
Registration fee – this product is only used for new members who register through the website
Advanced settings
Depending on the selected package, advanced settings are available:
Term transition – used for new members; within the configured transition period, no invoice is created for the current term, but for the next contribution term instead
Pro rata – used for new members; the contribution for the current term is calculated based on the number of remaining days.
Contribution levels
For a collective, you can set up multiple contribution levels. A level applies once a specified number of members within the collective is reached. You can assign a separate product to each contribution level and specify whether it applies per member or to all members combined.
We use the standard level for members without a collective or for collectives with only one member.
Multiple products and multiple levels
When both multiple products and multiple levels are configured, the calculation becomes more complex. We apply the following rules:
Standard level – the contribution products are applied in the same way as for individual contributions
Other levels – the configured contribution product is used as a replacement for the first contribution product. Any additional contribution products are applied per member within the collective, in the same way as for individual contributions.
