What are pricing rules in Nembol?
A pricing rule is an automatic price adjustment that Nembol applies per channel. You keep a single price on each product in Nembol, and the rule decides what that product costs on that particular channel: a percentage up or down, a fixed amount up or down, and optionally rounded to the nearest .99.
The rule is applied at the moment Nembol publishes the product to the channel. The price stored in Nembol never changes — it stays your reference price, and each channel receives its own calculated version of it. That is how the same product can sit at one price on your own store and a higher one on a marketplace that charges you fees.
Rules are set per channel, not per product. Once a rule is configured for a channel, it applies to everything you publish there.
They also work as a bulk price edit. A pricing rule is not only for new listings. If you change the rule on a channel where products are already published, those products take the new price as well — not instantly, but the next time each one is updated. You can force that with the Retry or Update button, which re-sends up to 500 products at a time, so raising or lowering prices across a whole channel is one setting change instead of editing products one by one.
Sellers typically use a pricing rule to:
- Adjust for exchange rates when they sell in different currencies on different channels.
- Cover the listing or commission fees a marketplace charges them.
- Earn back the cost of an advertising campaign on the channel running it.
- End every price on .99 without recalculating anything by hand.
There are three kinds of rule, each described below:
- Raise or lower prices by a percentage.
- Raise or lower prices by a fixed amount.
- Round the resulting price to the nearest .99.
How to create a pricing rule in Nembol
All three rules live in the same place: open the Channels tab in Nembol, go to Common Settings, then to the “Price rules” section. Choose the channel the rule should apply to, then set the adjustment.
Note: Pricing rules are applied at the channel level, not to individual products. This means that once a pricing rule is configured, it will affect all products in that channel.
Pricing rule expressed as a percentage
Setting a pricing rule in percentage is extremely useful for sellers who use different currencies on different channels and need to adjust the price according to the exchange rates.
Creating a pricing rule is really simple. This is how you do it in Nembol.
- Open the Channels tab in Nembol.
- Visit the Common Settings, and then go to the “Price rules” section.
- Click on the percentage icon.
- Fill the blank typing the price you want to apply.
Example: type 20 or +20 if you want your prices to be 20% higher.
$100 + 20% = $120
Example: type -15 if you want your prices to be 15% lower.
$100 + (-15%) = $85
!!! Remember the minus if you want to apply a discount to your prices!
Pricing rule as a fixed amount
With Nembol, you can set differentiated prices according to the target channel you want to list.
Indeed, to compensate for the high listing fees of certain channels or get some money back from your last ad campaign, you might need to label your product with higher/lower prices on a specific channel. To do it, you can use the pricing adjust feature, and type the amount you want to price your products.
To set a different price, all you need to do is:
- Open the Channels tab in Nembol.
- Visit the Common Settings, and then go to the “Price rules” section.
- Click on the $ icon.
- Fill the blank typing the price you want to apply.
Example: type 1 or +1 if you want your prices to be $1 higher.
$100 + (1) = $101
Example: type -1 if you want your prices to be $1 lower.
$100 + (-1) = $99
Automated rounding to .99
Additionally, using Nembol you can use the automatically round function, which rounds the resulting price to the nearest -.99 price.
To use it, remember to select the channel on which you want to use this feature. (screenshot below)
Nembol does this because buyers are used to psychological thresholds.
Example A: if your price in Nembol is 119.00, and you apply a 5% discount, the math gives you a price of 113.05. Nembol will adjust this price to 112.99.
Example B: if you list a product in Shopify with a +10 adjustment, its price will be 10% higher in Shopify than what is shown in Nembol, rounded to the nearest .99. If you then edit the adjustment from +10 into +8, that product price will not change immediately, but will indeed change once you make any edit in Nembol (you just have to open that product and save it again) or receive any edit from any connected channel, including inventory changes coming from sales in other channels.
With the Retry or Update button, Nembol lets you apply price changes to multiple products at once, up to 500 at a time, without having to edit them individually. This makes it easy to see updated prices across channels.
Automated rounding to .99 for small prices
Automated rounding works especially well with prices larger than 10$.
On the other side, this function distorts price adjustments on prices smaller than 10$.
Example: $100 + 10% = 110$, approximated to 109,99$ — Works fine!
$2 + 10% = $2.20, approximated to $1.99 — Not really useful.
This is why we automatically deactivated it for all prices smaller than 10$.
Everyone can get the best out of this function when listing multichannel.
