Create Repricer Modal - V1 configuration interface

📋 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.

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).

🚪 Opening the Create Modal

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

Button	Icon	What it does
Add New	+	Opens the Repricer Management modal in Create mode. Use this for manual one-at-a-time rule creation.
Import CSV	file	Opens the separate 4-step Bulk Import modal (Connection → Upload → Validation → Import) for creating dozens or hundreds of rules at once.
Export	↓	Downloads your product list pre-filled with fees, the recommended starting template for Bulk Import.

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)

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.

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.

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.

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.

Strategy-specific fields

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.

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

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.

5. Pricing Rules Card

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

1

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.

2

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."

3

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%.

4

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.

5

Maximum Price (optional)

Absolute ceiling. Leave empty to let the engine raise freely up to Max Margin.

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.

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:

Card	Shows
Min Price (blue)	Base price + shipping - VAT - Amazon fees (with sub-breakdown for referral / FBA fulfillment) - COG, then Profit on a separate bolded line, and the 30-day Avg Sell Price underneath for context.
Max Price (gray)	Same breakdown applied at the Maximum Price. Quickly see the profit ceiling.

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

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.

---

🎬 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.

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.

---

📦 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:

1

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.

2

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.

3

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.

4

Import

Final confirmation screen showing the profit range across all valid rows. Click Import to create every rule in one transaction.

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.

---

⚙️ 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:

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

❓ FAQ

Why doesn't the product dropdown show my new ASIN?

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.

What's the difference between Min Margin and Minimum Price?

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.

Can I fetch Amazon fees for all my rules at once?

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.

What happens if I delete a rule, does my listing price revert?

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.

Can a single rule cover multiple marketplaces?

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.

Why is my Create button disabled?

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.
