![Create Repricer Modal - V1 configuration interface](/files/27a5gJUTrXte51pkhZVF)

## 📋 Overview

The **Create Repricer** flow in SellerMagnet V1 lives in a single full-page modal that handles both **creating new repricer rules** and **editing existing ones**. It's designed as one visually structured form, three stacked configuration cards on the left, a live profit preview on the right, so you can configure a rule, see the margin impact in real time, and commit in under a minute.

{% hint style="info" %}
**One modal, two modes.** The same modal opens whether you click **Add New** or click an existing row. A blue badge at the top (`CREATE` or `SAVE`) tells you which mode you're in. In Edit mode the product selector is replaced with the chosen product and four extra tabs appear (Settings / Recommendations / Analysis / Sales History).
{% endhint %}

***

## 🚪 Opening the Create Modal

From the **Repricer Dashboard**, three toolbar buttons in the top-right get you into the creation flow:

<table><thead><tr><th width="200">Button</th><th width="80">Icon</th><th>What it does</th></tr></thead><tbody><tr><td><strong>Add New</strong></td><td><code>+</code></td><td>Opens the Repricer Management modal in <strong>Create mode</strong>. Use this for manual one-at-a-time rule creation.</td></tr><tr><td><strong>Import CSV</strong></td><td><code>file</code></td><td>Opens the separate 4-step <strong>Bulk Import</strong> modal (Connection → Upload → Validation → Import) for creating dozens or hundreds of rules at once.</td></tr><tr><td><strong>Export</strong></td><td><code>↓</code></td><td>Downloads your product list pre-filled with fees, the recommended starting template for Bulk Import.</td></tr></tbody></table>

Clicking a row in any of the 4 status tabs (Inactive, Brand-PL, Running, Buy Box Secured) opens the same modal in **Edit mode** instead.

***

## 🧭 Modal Anatomy

Once the modal is open you'll see five distinct regions, each handling a different part of the configuration.

### 1. Product Header

Runs across the full width of the modal above the configuration cards. It shows the product you're repricing:

* **Product image, title, SKU (Stock Keeping Unit), and ASIN (Amazon Standard Identification Number)**
* **Marketplace flag + name** (e.g. Amazon.de)
* **Fulfillment badge:** FBA (blue) or FBM (amber)
* **Stock badge:** current units in inventory
* **Five price tiles:** Current / Minimum / Maximum / BuyBox / New Offers

In Create mode this section is **empty until you pick a product** from the dropdown below.

### 2. Product Selector (Create mode only)

{% hint style="warning" icon="triangle-exclamation" %}
**You cannot type an ASIN here.** The dropdown is populated from your **synced Active Amazon products**. If a product you want to reprice is missing, verify it's Active in Seller Central and wait for the next sync cycle.
{% endhint %}

A single `<select>` dropdown labeled **Select Product** lists every active product from every connected marketplace. Pick one, the Product Header above populates and the three configuration cards + Live Preview become interactive.

### 3. Strategy Configuration Card

The first configuration card (chess-knight icon, top-left of the form area). This is where you pick HOW the rule competes.

{% tabs %}
{% tab title="Strategy picker" %}
**Strategy** (required), dropdown of every supported strategy. Each option has a short description that appears in a blue info box directly below the dropdown once selected. A "Learn more" link takes you to the full [Repricing Strategies Overview](/selling-tools/repricer-overview/repricing-strategies-overview.md).

**Active toggle** (top-right of the card), switch the rule on/off without deleting it. Paused rules stay in the Inactive tab.

**Expiry Date** (optional), pick a `datetime-local` value. The rule auto-stops at that moment. Leave empty to run indefinitely.
{% endtab %}

{% tab title="Strategy-specific fields" %}
Different strategies expose different sub-fields that appear dynamically below the picker:

<table><thead><tr><th width="220">Strategy family</th><th>Extra fields</th></tr></thead><tbody><tr><td><strong>Position-based</strong></td><td><code>Position</code>, integer, default <code>1</code>, minimum <code>1</code>. Determines which rank you target.</td></tr><tr><td><strong>Same Price as Seller</strong></td><td><code>Seller ID</code>. Amazon seller identifier to mirror.</td></tr><tr><td><strong>Brand Guard / Competitive</strong></td><td><code>Competitor ASINs</code> (comma-separated), <code>Sales Velocity</code> (days, default 7), <code>Low Stock</code> (default 10), <code>High Stock</code> (default 50).</td></tr><tr><td><strong>Competitor ASIN Sync</strong></td><td><code>Competitor ASIN</code>, <code>Price Adjustment Factor</code> (0.5–1.5, step 0.01, default 1.0).</td></tr><tr><td><strong>Lowest Price / MAP (Minimum Advertised Price) / Brand-PL</strong></td><td>No extra fields, strategy-driven by the Min/Max price and margins you set in Card C.</td></tr></tbody></table>
{% endtab %}
{% endtabs %}

### 4. Cost Basis Card

The second configuration card (coins icon). Everything you pay for the product, used by the Live Preview to calculate real profit.

<table><thead><tr><th width="200">Field</th><th width="110">Type</th><th>Notes</th></tr></thead><tbody><tr><td><strong>Purchase Price</strong> *</td><td>€ number</td><td>Unit cost paid to your supplier. Required, without it the profit calculation is wrong.</td></tr><tr><td><strong>Shipping Cost</strong></td><td>€ number</td><td>Per-unit inbound shipping (FBA) or outbound (FBM). Optional but recommended.</td></tr><tr><td><strong>VAT %</strong></td><td>% number</td><td>VAT or sales-tax rate to deduct. Defaults to your marketplace standard (19% for DE, etc.).</td></tr><tr><td><strong>Fee %</strong></td><td>% number</td><td>Amazon referral + FBA fees as a percentage. Click the <strong>Fetch</strong> button next to this field to pull the current live rate from Amazon automatically.</td></tr><tr><td><strong>Miscellaneous Cost</strong></td><td>€ number</td><td>Flat per-unit cost not covered elsewhere (packaging, labels, inspection, etc.).</td></tr><tr><td><strong>Miscellaneous Fee %</strong></td><td>% number</td><td>Percentage fee not covered elsewhere (e.g. 3PL fees).</td></tr></tbody></table>

{% hint style="success" icon="rocket" %}
**Pro tip:** Always click **Fetch** for Fee %. Amazon's referral percentage varies by category (8-15%) and Fetch pulls the correct value for *this* ASIN, much more accurate than typing a guess.
{% endhint %}

### 5. Pricing Rules Card

The third configuration card (sliders icon). The margin and price boundaries that constrain where the engine can go.

{% stepper %}
{% step %}

#### Margin Calculation Basis

Dropdown with two options:

* **Based on Sale Price (Default):** margin = profit ÷ sale price. Standard e-commerce margin.
* **Based on COGs (Markup):** margin = profit ÷ cost of goods. Useful if you think in markup terms rather than margin.
  {% endstep %}

{% step %}

#### Min Margin \*

The lowest profit margin (%) the rule is allowed to accept. If a proposed price would produce less margin than this, the engine stops at Min Price instead. Example: `8%` means "never sell at less than 8% margin no matter what."
{% endstep %}

{% step %}

#### Max Margin \*

The highest margin (%) the rule targets. Acts as a soft upper bound, the engine will not raise prices beyond this margin even if the Buy Box is uncontested. Example: `35%`.
{% endstep %}

{% step %}

#### Minimum Price \*

Absolute hard floor. The rule will never set a price below this value, regardless of what Min Margin calculates. This is your last-line-of-defense guardrail.
{% endstep %}

{% step %}

#### Maximum Price (optional)

Absolute ceiling. Leave empty to let the engine raise freely up to Max Margin.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
**Min Margin vs Minimum Price : they both floor the price.** The engine uses **whichever is higher**. If Min Margin calculates a €42.00 floor but Minimum Price is €39.90, the effective floor is €42.00. This is by design, margins take priority over static prices.
{% endhint %}

### 6. Live Preview / Price Breakdown

The right column of the modal, a green `LIVE PREVIEW` pill indicates this panel updates in real time as you type in the cost/pricing fields. It shows two stacked price cards:

<table><thead><tr><th width="150">Card</th><th>Shows</th></tr></thead><tbody><tr><td><strong>Min Price</strong> (blue)</td><td>Base price + shipping - VAT - Amazon fees (with sub-breakdown for referral / FBA fulfillment) - COG, then <strong>Profit</strong> on a separate bolded line, and the <strong>30-day Avg Sell Price</strong> underneath for context.</td></tr><tr><td><strong>Max Price</strong> (gray)</td><td>Same breakdown applied at the Maximum Price. Quickly see the profit ceiling.</td></tr></tbody></table>

Below the two cards: a full-width blue **Fetch Amazon Fees** button that re-fetches referral/FBA fee data from Amazon.

{% hint style="danger" %}
**Red warning banners** appear at the bottom of the Live Preview if any of these conditions are true:

* **Min price is below the current Buy Box:** you'll sell but probably at a loss.
* **Min price is above the current price:** you'll jump the listing price upward.
* **Max price is below the Buy Box:** your rule can never take the Buy Box.
  {% endhint %}

***

## 🎬 Action Bar

Fixed to the bottom of the modal:

* **Reset** (gray, rotate icon): clears all fields back to defaults. Use with caution, no confirmation.
* **Create Repricer** (blue, plus icon): validates and saves. If any required field is missing the modal highlights it in red and the button is disabled.

In **Edit mode** the Create button is replaced with a blue **Save** button that posts to the update endpoint instead.

***

## ✏️ Editing an Existing Rule

Click any row in the Repricer dashboard table, the same modal opens in **Edit mode** with:

* The `SAVE` mode badge replacing `CREATE`
* The product pre-selected (selector hidden)
* All current strategy + cost + pricing values pre-populated
* **4 extra tabs** at the top of the form area: Settings / Recommendations / Analysis / Sales History, so you can see historical performance alongside the current configuration

Change whatever you need, click **Save** to commit.

{% hint style="info" %}
**No rebuild needed.** Edits apply immediately on Save, the engine picks up the new parameters at its next evaluation cycle (approximately every 5 minutes). You don't need to pause-and-restart the rule.
{% endhint %}

***

## 📦 Bulk Import (Separate Modal)

For creating many rules at once, use **Import CSV** instead of Add New. This opens a separate wizard modal with four numbered stepper tabs:

{% stepper %}
{% step %}

#### Connection

Pick which marketplace account the rules should be created under. All rules in a single import go to one marketplace, import separately if you're creating rules for DE, FR, UK, etc.
{% endstep %}

{% step %}

#### Upload

Drag-and-drop your CSV file into the drop zone or click to browse. SellerMagnet auto-detects the column mapping if you used the Export template. A banner appears at the top if a previous session is still restorable.
{% endstep %}

{% step %}

#### Validation

The wizard parses every row and shows a validation table with three filters:

* **Errors:** rows that will be rejected (missing required fields, invalid ASINs, min > max, etc.)
* **Warnings:** rows that will import but needs your review (min below current Buy Box, etc.)
* **Valid:** rows ready to import

You can **Edit**, **Fetch Fees**, or **Delete** any row inline. A **Bulk Strategy** selector at the top lets you apply one strategy to every valid row in one click.
{% endstep %}

{% step %}

#### Import

Final confirmation screen showing the profit range across all valid rows. Click **Import** to create every rule in one transaction.
{% endstep %}
{% endstepper %}

{% hint style="success" %}
**Get the template right:** Click **Export → Products & Fees** from the Repricer toolbar BEFORE filling in your CSV. This gives you a pre-filled file with every synced product and their current fees. All you need to add is Min Price, Max Price, and Strategy.
{% endhint %}

***

## ⚙️ Managing Rules After Creation

Once rules exist, the Repricer Dashboard shows them in 4 status tabs (Inactive / Brand-PL / Running / Buy Box Secured). From the main items table you can:

<table><thead><tr><th width="220">Action</th><th>How</th></tr></thead><tbody><tr><td><strong>Edit one rule</strong></td><td>Click the row anywhere.</td></tr><tr><td><strong>Pause / Restart</strong></td><td>Use the Manage column action menu, or the Active toggle inside the edit modal.</td></tr><tr><td><strong>Delete one rule</strong></td><td>Manage → Delete. Confirmation prompt.</td></tr><tr><td><strong>Bulk action</strong></td><td>Select rows with checkboxes, then use the bulk toolbar (Start, Stop, Delete, Export) that appears above the table.</td></tr><tr><td><strong>Search</strong></td><td>Search bar filters by SKU, ASIN, or product title in real time.</td></tr></tbody></table>

## ❓ FAQ

<details>

<summary><strong>Why doesn't the product dropdown show my new ASIN?</strong></summary>

The dropdown is built from your **Active Amazon products** as of the last sync. If you recently added a listing in Seller Central, wait 10-15 minutes for the next sync cycle. If it still doesn't appear, verify the listing status is `Active` (not `Incomplete` or `Suppressed`) in Seller Central.

</details>

<details>

<summary><strong>What's the difference between Min Margin and Minimum Price?</strong></summary>

**Min Margin** is dynamic : it floats based on your cost + fees. **Minimum Price** is a static value you enter directly. The engine always uses **whichever produces the higher floor**, so margins protect you when fees spike and the static price protects you when costs drop.

</details>

<details>

<summary><strong>Can I fetch Amazon fees for all my rules at once?</strong></summary>

Yes, use the Bulk Import validation screen's **Fetch Fees** bulk action. It calls Amazon's fee preview API for every valid row and populates the Fee % column. Much faster than opening each rule individually.

</details>

<details>

<summary><strong>What happens if I delete a rule, does my listing price revert?</strong></summary>

No. Deleting a repricer rule stops further automatic updates but **does not change the current listing price**. The price stays wherever the engine last set it. If you want to revert, update the price manually in Seller Central or the Repricer's sister tools.

</details>

<details>

<summary><strong>Can a single rule cover multiple marketplaces?</strong></summary>

No, one rule = one listing on one marketplace. If you sell the same product on DE/FR/IT, create three separate rules. Bulk Import is the easiest way to do this.

</details>

<details>

<summary><strong>Why is my Create button disabled?</strong></summary>

At least one required field is empty or invalid. The form highlights problem fields in red. The most common cause is Strategy not selected, Purchase Price empty, or Min Margin / Max Margin / Minimum Price missing.

</details>
