Tariffs and payments#
In the discussion you pay for post visibility — highlighting, Topbox and show links.
Starting a topic is paid for in the category, not with a tariff
A paid category (without Free) and its price list are set on the category — see Paid topic creation. Replies are always free and there is no paid entry to the whole forum. Who may write depends on whether the forum is open to visitors who are not logged in — see the module overview.
The tariff#
| Field | Meaning |
|---|---|
| Name, title, description | per language |
| Validity in days | how long the promotion lasts |
| Credits | the price in credits |
| Active | |
| Druh plnění (supply kind) | required; what the tariff sells for VAT purposes — together with the seller's status and the customer's country it decides the VAT rate and the kind of document, see Taxes |
Prices are entered per combination of region and payment gateway. Payment by premium SMS can be set up too.
Without a price for a combination the tariff is not offered
Nothing reports it. After adding a gateway or a region, go through the price lists.
No VAT percentage is entered on the tariff. The rate comes from the pair supply kind × country as of the date of supply and is managed under Platby a měny → Daně — see Supply kinds and rates. Without a supply kind the tariff cannot be saved — the form reports "Vyberte druh plnění." (select a supply kind).
The Typ produktu (fakturace) and Sazba DPH (%) fields are gone from the form
The supply kind replaced them. An older tariff keeps its product type and saving does not change it; a new tariff gets one from the nature of its supply kind — goods → Zboží (goods), anything else → Služba (service). The product type still helps pick the document layout. An older tariff with no supply kind yet is charged with the default supply kind from Taxes; you have to choose one the first time you edit it.
A supply kind with no rate in the customer's country = the tariff cannot be paid for
If Taxes has no rate for the supply kind and the country the tax is worked out for, the payment form shows the customer "Cenu s DPH se teď nepodařilo spočítat. Zkuste to prosím za chvíli znovu." (the price incl. VAT could not be calculated right now) and refuses to submit. After choosing a supply kind, check it has rates in every country you sell to.
Tariff prices are entered excluding VAT
Whether and by how much the entered price is raised at payment is decided by the system from the supply kind, the seller's status and the customer. When VAT is charged, the payment form shows the price incl. VAT with the base "excl. VAT" under it; a seller who is not VAT registered charges the entered price unchanged. In detail in Tariffs and membership. Premium SMS is the exception — see below.
The premium SMS price is entered as the FINAL price, including VAT
It is exactly what the customer pays the operator. Beside the field the form shows Cena bez DPH: (price excl. VAT, from the region's Sazba DPH on the Ceník tab) — as a hint only, it is not stored anywhere.
The tariff price list: what you fill in is what applies#
Tariff prices are entered under Diskuze → Tarify, in the tariff form on the Price list tab. For every payment region there is a row for each payment gateway. The price is stored in the currency the gateway uses in that region — exactly the one the payment form on the website looks for.
| Price-list element | What it is for |
|---|---|
| Sazba DPH (VAT rate; a select on each region) | pre-filled with Výchozí DPH (%) (default VAT) from the invoicing settings; stored on every price of the region. It does not decide the VAT on the payment or on the document — the supply kind does. It only feeds the Cena bez DPH: (price excl. VAT) hint on the Expres ceník (express prices) tab and serves as a fallback rate for documents of older payments |
| Cena bez DPH (price excl. VAT) | the price that is stored; for a seller who is not VAT registered it is final |
| Cena s DPH (price incl. VAT) | a helper field only, not stored. It is worked out from the rate of the chosen supply kind in the region's country (a region without a country → the country of the default seller). It works both ways: fill in the price incl. VAT and the base is worked out. If the kind has no rate in that country, or no kind is chosen yet, it stays empty |
| Konečná cena (final price) | for a gateway with final prices enabled and for a price list in credits, a single field instead of the pair; the customer pays exactly this amount |
| Aktivní (active) | unticked, the tariff cannot be bought through that gateway |
The price incl. VAT is indicative
The field uses the rate of the region's country. What the customer really pays is decided only at payment, by their country and by whether they are a company with a verified VAT ID — a company from another EU state may thus pay just the base. See Taxes.
What is stored depends on what you do in the row:
| What you do in the row | What is stored |
|---|---|
| fill in a price and tick Active | a price-list row; the tariff can be bought through that gateway |
| fill in a price without Active | the price-list row is stored, but on the website the tariff is shown as "cannot be purchased" through that gateway |
| leave the price empty | nothing; the tariff cannot be bought through that gateway |
| clear a filled-in price | the price-list row is removed |
| enter 0 | a valid price of 0, not an empty field |
| tick Active without a price | saving is refused with "An active price must be filled in — either enter a price or untick "Active"." |
Prices in another currency are shown but not edited
If the tariff has old prices in a currency other than the one the gateway uses in the region (typically after the gateway's currency changed), the form shows them in the box "Prices in a currency the gateway does not use in the region". The website does not offer them to customers and saving the tariff leaves them unchanged. Enter a valid price in the row with the current currency.
Step by step: pricing a tariff#
- On the Základní (basic) tab choose the Druh plnění (supply kind) — without it the Cena s DPH field stays empty.
- Switch to the Ceník (price list) tab and fill in Cena bez DPH for the region and gateway. To start from the final amount, type it into Cena s DPH and the base is worked out for you.
- Tick Aktivní.
- Save, then open the payment form on the website and check that the amount matches.
Promotion#
A promoted post is sorted to the top of the listing.
Promotion is delivered by one specific tariff
Other tariffs do not extend it, even with a validity filled in.
Topbox and show links#
| Tariff | What the customer gets |
|---|---|
| Topbox | For the validity period the post shows in the "TOP" side panel on the module pages. |
| Show links | Web addresses in the post text are clickable links on the detail (search engines do not follow them). |
Without the tariff an address in the post text stays plain text.
What happens after payment#
- The payment moves to paid.
- The payment item is activated.
- The post's promotion is extended.
Extension only goes up
Pay twice and you get the sum.
Manual intervention#
You find the post's payment items on the Platby tab of its edit form, and all of them together under Diskuze → Platby. Each item carries a tariff, Valid until and an Active switch. The post's promotion is calculated from its active items — and is recalculated after every manual change:
| What you do | What happens to the promotion |
|---|---|
| add an item | it is extended |
| delete an item | it is recalculated without it, possibly to nothing |
| switch Active off (in the form and with the switch in the payment list alike) | it is recalculated as if the item did not exist |
| change the item's Post to another one | it is recalculated for both the new and the original one |
Procedure: move a payment to another post#
- Open Diskuze → Platby and choose edit on the item.
- In the Post field, pick the right post.
- Save. The promotion is recalculated for both.
Removing or switching off an item shortens the promotion
Unlike paying, a manual change counts in both directions — remove or switch off an item and the promotion is recalculated downwards, possibly to nothing.
Handle compensation by adding an item, not by overwriting a date
An added item is traceable. A hand-typed date is not, and the next payment recalculates it anyway.
Is promotion worth it on a forum?#
On a small forum, probably not
A promoted post at the top is worth something where there are so many topics that new ones sink. On a forum with ten topics a month nobody notices.
