Create & Manage Repricer Rules
Complete walkthrough of the SellerMagnet V1 Create Repricer modal, product selection, strategy configuration, cost basis, pricing rules, live profit preview, and edit/bulk-import flows.
Difficulty: 🔴 Advanced · Reading time: ~10 min

📋 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:
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 (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.
Different strategies expose different sub-fields that appear dynamically below the picker:
Position-based
Position, integer, default 1, minimum 1. Determines which rank you target.
Same Price as Seller
Seller ID. Amazon seller identifier to mirror.
Brand Guard / Competitive
Competitor ASINs (comma-separated), Sales Velocity (days, default 7), Low Stock (default 10), High Stock (default 50).
Competitor ASIN Sync
Competitor ASIN, Price Adjustment Factor (0.5–1.5, step 0.01, default 1.0).
Lowest Price / MAP (Minimum Advertised Price) / Brand-PL
No extra fields, strategy-driven by the Min/Max price and margins you set in Card C.
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.
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.
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:
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
SAVEmode badge replacingCREATEThe 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:
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.
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:
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.
