Cart Extras

Introduction

Cart Extras turns your shopping cart into a sales tool: your customers can see how far they still are from their next reward — and at the same time you make sure that small orders remain profitable for you.

What this plugin does for you

• It increases your average order value. A progress bar in the cart shows every customer how much is missing until the next goal, for example “Only €5.30 left to 5% discount”.
• It rewards automatically. As soon as a customer reaches a step, the plugin puts a discount or a free product into the cart. Nobody has to enter a voucher code and you do not have to maintain anything manually.
• It makes small orders viable. If the cart value stays below your minimum order value, the plugin adds a small order surcharge — exactly the amount that is missing. As soon as the customer orders enough, the surcharge disappears by itself.
• It keeps you in control per shop. If you run several sales channels, you decide for each one individually whether and how the features apply.

Who is this plugin for?

For shop operators and editors who work without programming knowledge. Everything is configured in the Shopware Administration — there is no file you would have to edit.

Installation

After your purchase the plugin is available directly in your Administration — there is nothing to download.

1. Log in to your Shopware Administration.
2. Open Extensions in the main menu on the left and go to My extensions.
3. Find the entry Cart Extras in the list and click Install next to it.
4. Then switch the plugin on using the toggle to the left of the entry. When the toggle is blue, the plugin is active.

If Cart Extras does not appear in the list, your Shopware account is not yet connected to this shop. You establish the connection in the same area on the Shopware Account tab; the plugin then appears automatically.

Getting started

Three steps are enough to get your first progress bar running:

1. Open the settings: In the Cart Extras row, click Configure.

   Fig. 2: The settings of the plugin

2. Switch the progress bar on: The bar is switched off on delivery. Turn on Progress Bar Active and click Save in the top right corner.

3. Create your first step: Open Catalogues → Progress Bar Steps and create a step, for example “Free shipping” from an amount of 50. The details are described in Setting up the progress bar with steps.

   Fig. 3: The configured steps at a glance

4. Check the result: Switch to your shop, put a product into the cart and click the cart icon in the header. The cart slides in from the side — and shows the progress bar together with the amount that is missing until the next goal.

Settings

You reach the settings via Extensions → My extensions and the Configure link in the Cart Extras row.

Fig. 4: All settings of the plugin at a glance

At the very top you choose under Sales Channel which shop the settings below apply to. With All Sales Channels you define the basic setting for every shop; select an individual sales channel to deviate from it on purpose. The to documentation button opens this manual online at any time.

After every change, click Save in the top right corner.

Enable plugin for this sales channel

This toggle is the master switch. When it is off, neither the progress bar nor the step rewards nor the small order surcharge take effect in this sales channel — your settings and steps are kept. It is switched on by default.

What it is good for: You run a B2B and a B2C shop and only want to show the rewards to end customers. Simply switch the plugin off in the B2B channel instead of uninstalling it.

Progress Bar Active

This toggle shows the progress bar in your customers’ cart. It is switched off by default — without it the cart stays unchanged, even if you have already created steps.

Important: The toggle only controls the display. Discounts and free products stored in your steps are still granted while the bar is hidden. To stop a reward completely, switch off the step in question (see Setting up the progress bar with steps).

What it is good for: You can prepare your steps in peace and only switch the bar on when the campaign is supposed to start.

Show progress bar in shopping cart, offcanvas and checkout

This toggle decides where your customers see the bar: on the cart page, in the cart sliding in from the side (offcanvas) and in checkout — on the registration page under the headline, and on the order confirmation directly above the line item list. It is switched on by default.

What it is good for: Switching it off hides the bar in all four places without having to disable Progress Bar Active entirely — discounts, free products and the small order surcharge keep working regardless.

Show Thresholds in Progress Bar

When this toggle is on, your minimum order value also appears as an additional goal in the progress bar. Customers then see in the same bar from which amount the small order surcharge no longer applies. The display is switched on by default.

What it is good for: The surcharge feels much less like a penalty when customers immediately see how little is missing for a surcharge-free order.

Progress Bar Color

Here you define the colour of the filled bar — either with the colour field on the left or by entering a colour value. Choose a colour that matches your shop design and stands out well from the background.

Milestone Color

This colour is used for the dots on the bar that mark your individual steps. A clear contrast to the bar colour helps your customers see how many goals are still ahead of them.

Setting up the progress bar with steps

What this does for you: Every step is a goal in your customers’ cart — with a name, an amount and, optionally, a reward. The progress bar shows how far it still is, and the plugin grants the reward automatically as soon as the amount is reached.

You find this area under Catalogues → Progress Bar Steps.

Fig. 5: For each step the overview shows whether it is active, what it is called, from which amount it applies and in which order it is sorted

The selection field next to the headline switches the language. Names and descriptions of your steps are maintained separately per language — that way customers read the goal texts in the language of their shop.

How to create a step

1. Click Add Step in the top right corner.

2. Fill in the General Information card:

   Fig. 6: The basic data of a step

   • Name: the text your customers read in the cart, for example “Free shipping”.
   • Amount: the cart value from which the step is reached. Only the value of the products in the cart is counted — surcharges, discounts and free products added by the plugin are deliberately left out, so that progress cannot push itself upwards.
   • Description (Tooltip): an explanatory sentence that appears below the name in the goal list, for example “Free delivery for orders from €50.”
   • Priority: determines the order in which your steps are sorted. Assign the values in steps of ten so that you can conveniently squeeze in another step later.
   • Active: only steps that are switched on appear in the cart and grant their reward.

3. Click Save in the top right corner.

Tip: Create your steps with increasing amounts — for example €50, €100, €150. That gives customers a comprehensible ladder instead of a random list.

How to reward a step with a discount

What this does for you: As soon as the customer reaches the amount, the plugin deducts the discount from the cart automatically. The discount appears as a separate line carrying the name of your step.

1. Open the step in question and scroll to the Action card.

2. Select Discount under Action type.

   Fig. 7: A step that grants 5% discount from the stored amount

3. Define how the discount is calculated:

   • Discount type Percentage (%): the Discount value is a percentage of the goods value. This variant adapts automatically to large and small orders.
   • Discount type Absolute amount: the Discount value is a fixed amount. In addition you select the Currency the amount refers to.

4. Under Behaviour with multiple discounts, define what happens when a customer reaches several discount steps at the same time:

   • Replaces lower discounts (only the highest applies) (default): if a customer reaches, say, a 10% and a 20% step of the same discount type at once, only the 20% applies. A higher step upgrades the lower one instead of stacking on top of it.
   • Adds up with other discounts: this step’s discount is granted in addition to every other discount already reached.

   Replacing discounts only compete with steps of the same discount type — a percentage step and an absolute step never cancel each other out, because they are different promises to the customer. With two absolute discounts in different currencies, the actual discount amount in the current cart decides which one is higher.

5. Click Save in the top right corner.

Important: The discount stays in the cart as long as the customer is above the amount of the step. If goods are removed and the value drops below it, the discount disappears automatically.

Existing installations: If you already had several discount steps in use before this feature, the update automatically sets them to Replaces lower discounts. If your discounts used to stack on purpose, switch the affected steps to Adds up with other discounts manually.

How to reward a step with a free product

What this does for you: From the stored amount onwards the plugin puts a product of your choice into the cart free of charge — visible, with its name and a price of €0.00.

1. Open the step in question and select Free product under Action type in the Action card.

   Fig. 8: A step that adds a free article from the stored amount onwards

2. Under Free product, select the article your customers receive as a gift.

3. Under Quantity, enter how many pieces are added.

4. Click Save in the top right corner.

Tip: Choose an article that is available in sufficient quantity and that is sold in the relevant sales channel — otherwise the gift cannot be shown in the shop.

Important: The free product does not count towards the goods value. So it never pushes your customers over the next step by accident.

How to offer a step to selected customers only

What this does for you: You can limit a reward to specific situations — for example to a customer group, a country or a campaign period. For this you use the rules you already maintain in Shopware anyway.

1. Open the step and scroll to the Rules card.
2. Select one or more rules in the Select rules… field.
3. Click Save in the top right corner.

If at least one of the selected rules applies to the customer, the step is visible to them and its reward is granted. If you leave the field empty, the step applies to all customers.

Setting up the small order surcharge

What this does for you: You define a minimum order value. If the cart stays below it, the plugin automatically adds a surcharge line — exactly the amount that is missing up to the minimum order value. So a customer never pays less than your minimum order value, and as soon as they order enough, the surcharge disappears by itself.

You find this area under Catalogues → Dynamic Thresholds.

Fig. 9: The overview of the configured thresholds

How to create a threshold

1. Click Add threshold config in the top right corner.

2. Fill in the General card:

   Fig. 10: The settings of the small order surcharge

   • Name: your internal name for this rule. Your customers never see it.
   • Active: only thresholds that are switched on are applied.

3. Fill in the Rules & Calculation card:

   • Threshold Amount: your minimum order value. The surcharge always equals the difference between the goods value and this amount.
   • Priority: decides which threshold wins if several apply at the same time — the one with the higher value prevails.
   • Tax Rate: the tax rate the surcharge is calculated with. As a rule, choose the same rate as for your main assortment.
   • Linked Rule (optional): limits the surcharge to specific situations, for example to a customer group or a delivery country. If you leave the field empty, the surcharge applies to everyone.
   • Cart Label: the text your customers read as a line in the cart, for example “Small order surcharge”. Maintain it in every language your shop offers.

4. Click Save in the top right corner.

Important: The surcharge only appears when there are actually products in the cart. An empty cart stays empty.

How to exclude categories and shipping methods

What this does for you: Not every article and not every shipping route should count. In the lower part of the Rules & Calculation card you exclude both in a targeted way.

Fig. 11: Exceptions for individual categories and shipping methods

• Excluded Categories: products from the categories selected here do not count towards the goods value. So anyone who only has such articles in the cart does not reach your minimum order value — and pays the surcharge. Typical use: vouchers, services or heavily discounted remainders.
• Excluded Shipping Methods: if the customer selects one of the shipping methods listed here, this threshold does not apply at all. Typical use: click and collect, where no shipping costs arise for you.

Then click Save in the top right corner.

Running several thresholds side by side

You can create several thresholds — for example a general one and a different one for business customers. Only one threshold is ever applied to a cart:

1. Excluded shipping methods are checked first. If the chosen shipping method does not fit, the threshold is skipped.
2. Of the remaining ones, the one with the highest Priority whose Linked Rule applies to the customer takes effect.

Tip: Give the general threshold without a linked rule the lowest priority. It then serves as a fallback for every case no special rule covers.

What your customers see

The progress bar appears in four places along the shopping journey: in the cart sliding in from the side (offcanvas), on the cart page, on the checkout registration page under the headline, and on the order confirmation directly above the line item list. All four are switched together via Show progress bar in shopping cart, offcanvas and checkout (see Settings). Discount, free product and small order surcharge are regular cart lines and therefore visible everywhere as well.

Below the minimum order value: The plugin adds the surcharge line with your label. In the example €35.10 are missing up to the minimum order value of €50 — and exactly this amount is charged as a surcharge.

Fig. 12: The surcharge fills the gap up to the minimum order value

On the way to the next step: Above the cart lines the bar appears together with a note about how much is missing until the next goal. The dots on the bar mark your steps.

Fig. 13: The progress bar shows how far it is to the next goal

All goals at a glance: When the customer clicks the note, the Upcoming goals list unfolds. Goals already reached are struck through, open goals are listed with their amount and your description below.

Fig. 14: The goal list makes all steps transparent

Along for checkout too: When the customer moves on to checkout, the bar keeps them company — here on the registration page, right below the Shipping information headline.

Fig. 14a: The same progress bar and goal text follow the customer into checkout

Reward reached: Discount and free product appear as separate lines — the discount with the name of your step and a negative amount, the free product with the product name and €0.00.

Fig. 15: Both rewards have arrived in the cart

Important: Surcharge, discount and free product are managed by the plugin. Your customers cannot remove them individually — they disappear on their own as soon as the condition is no longer met.

Troubleshooting

No progress bar appears in the cart

Why this happens: In most cases the display is still switched off, there is no active step — or you are looking at the wrong page.

How to fix it:

1. Open the settings of the plugin and check whether Progress Bar Active is switched on. Also check that you selected the correct Sales Channel at the top.
2. In the same area, check whether Enable plugin for this sales channel is switched on.
3. Check whether Show progress bar in shopping cart, offcanvas and checkout is switched on — without it the bar does not appear anywhere.
4. Open Catalogues → Progress Bar Steps and make sure at least one step is set to Active.
5. Check both the cart sliding in from the side (cart icon in the header) and the cart page itself in the shop — both show the bar.
6. Then clear the cache: Settings → System → Caches & indexes → Clear cache.

The small order surcharge is not calculated

Why this happens: Either the goods value is already high enough, or one of your exceptions applies.

How to fix it:

1. Under Catalogues → Dynamic Thresholds, check that the threshold is set to Active.
2. Compare the goods value with the Threshold Amount — if the cart is above it, everything is correct and no surcharge is due.
3. Check whether the customer chose a shipping method you listed under Excluded Shipping Methods.
4. Check whether the articles in the cart belong to a category listed under Excluded Categories.
5. If you stored a Linked Rule, check whether it applies to this customer at all.
6. Check whether there is a product in the cart at all — without a product there is no surcharge.

Discount or free product is not granted

Why this happens: The goods value is still below the amount of the step, or a rule prevents the reward.

How to fix it:

1. Compare the Amount of the step with the pure goods value. Surcharges, discounts and free products added by the plugin do not count here.
2. Check whether the step is set to Active.
3. Check the Rules card of the step: if a rule is stored there, at least one of them must apply to the customer.
4. For a free product: check that a product is actually selected in the Action card and that this product is available in the relevant sales channel.

Customers see the goal texts in the wrong language

Why this happens: Names and descriptions of the steps as well as the label of the surcharge are stored separately per language. If a language version is missing, the text of the original language remains.

How to fix it: Open the record, set the desired language in the selection field at the top, enter the texts in that language and save again.

A customer wants to remove the surcharge or the free product

Why this happens: Both are lines managed by the plugin and therefore deliberately cannot be deleted by hand.

How to fix it: Explain the way through the cart — adding more goods removes the surcharge automatically. If the rule should no longer apply at all, switch off the threshold or the step in the Administration.

FAQ

Q: Does my customer have to enter a voucher code?

A: No. The plugin puts discount and free product into the cart automatically as soon as the amount of the step is reached.

Q: Do I also see the progress bar on the cart page?

A: Yes. The bar appears in the cart sliding in from the side, on the cart page itself, on the checkout registration page and on the order confirmation — controlled by the shared Show progress bar in shopping cart, offcanvas and checkout toggle. Surcharge, discount and free product are regular cart lines anyway and therefore visible everywhere regardless.

Q: Is there a free-shipping action?

A: No. A step can only be rewarded with a discount or a free product. A step name like “Free shipping” without a stored action is just an intermediate goal on the bar — it does not unlock free shipping automatically; set up free shipping as usual through your shipping method’s cost configuration.

Q: Can I offer different steps per shop?

A: The master switch, the display of the bar and the colours are set per sales channel. The steps themselves apply shop-wide; to limit them to individual customer groups or situations, use the rules in the Rules card.

Q: How does all this behave in another currency?

A: The amounts you store are converted using the exchange rate of the respective currency. So you do not have to maintain your steps twice per currency.

Q: Does the free product count towards the next step?

A: No. Free products and discounts added by the plugin deliberately do not count towards the goods value — otherwise a customer could reach the next step through the reward alone.

Q: Can I run several minimum order values in parallel?

A: Yes. Only one is ever applied: the one with the highest priority whose rule applies and whose exceptions the cart does not trigger.

Q: What happens to existing carts when I change something?

A: The calculation runs again with every cart update. Your change therefore takes effect the next time the customer adds something to the cart or opens it.

Q: What happens if I switch the plugin off?

A: Surcharges, discounts and free products disappear from the carts and the bar is hidden. Your steps and thresholds remain stored and take effect again as soon as you switch the plugin back on.

For administrators / technical details

This section is aimed at technical administrators. You do not need it for day-to-day work with the plugin.

System requirements

• Shopware: 6.7
• PHP: 8.2 or newer
• Database: MySQL 8.0 / MariaDB 10.11 or newer

Installation via the command line

composer require swp/cart-extras-six
php bin/console plugin:refresh
php bin/console plugin:install SwpCartExtrasSix --activate
php bin/console cache:clear

Permissions for editors

Both areas of the plugin can be released individually in the role management. Under Settings → System → Users & permissions you find the permission groups Cart Extras: progress bar steps and Cart Extras: small order surcharge in a role — each with the levels read, edit, create and delete. This way an editor can maintain steps without being able to touch the minimum order value.

Interaction with other extensions

The plugin works exclusively with its own cart lines and its own tables; Shopware’s own tables stay untouched. The progress bar is hooked into the cart that slides in from the side. If you use a theme that heavily rebuilds this cart, check the display in the shop once after switching the plugin on.
