Restock Triggers: How Game Currency and Item Sellers Set Reorder Points Before Stock Runs Out

Why "it looks low" is a bad restock trigger

When you sell game currency, items, or accounts on several marketplaces, stock does not drain evenly. One marketplace may sell out in a day while another sits untouched for a week. If you restock by feel, you tend to make one of two mistakes:

• Restock too late. Offers go out of stock, you lose ranking momentum, and you scramble to prepare a batch under time pressure.
• Restock too early or too much. Capital sits in stock you cannot sell, and you carry more patch-day or price-drop risk.

A reorder point replaces the gut feeling with one number per product: when available stock falls to this level, start preparing the next batch.

The reorder point formula

You need three inputs, all from your own records:

1. Daily sales velocity: units sold per day across all marketplaces, averaged over a recent window.
2. Lead time: days between deciding to restock and having listable stock. This includes sourcing, farming, verifying, and preparing the upload file.
3. Safety buffer: extra days of cover for demand spikes and delays.

Reorder point = daily velocity × (lead time + safety days)

Worked example: game currency

Suppose you sold 560M units of a currency over the last 14 days across all marketplaces.

• Velocity: 560M ÷ 14 = 40M per day
• Lead time: 2 days
• Safety buffer: 1 day
• Reorder point: 40M × 3 = 120M

When total available stock drops to 120M, you begin preparing the next batch. You are not waiting for zero.

Worked example: game accounts

Suppose you sold 63 accounts of one tier over 21 days.

• Velocity: 63 ÷ 21 = 3 per day
• Lead time: 4 days, because accounts need verification
• Safety buffer: 2 days
• Reorder point: 3 × 6 = 18 accounts

Slower, more labor-intensive products need a higher reorder point relative to their velocity.

Choosing the right velocity window

The window you average over changes the answer, so pick it on purpose.

If you already run a weekly review, as described in our sell-through review workflow, recalculating velocity there keeps the numbers current without extra work.

Set safety days by risk, not by habit

One flat buffer for everything wastes capital on easy products and under-protects hard ones. Scale it by how painful a stock-out is.

• 1 day: commodity items you can source or prepare quickly.
• 2 days: products with verification or manual preparation steps.
• 3 or more days: products where supply is unreliable, or where a stock-out costs you a strong ranking.

Add a day temporarily around known events like patches, sales weekends, or holidays. Our peak-season prep plan covers how to schedule that earlier.

Splitting the buffer across marketplaces

The reorder point applies to your total sellable stock, but you still decide how much sits on each marketplace. Allocating it badly causes lost sales on the fast channel and idle stock on the slow one.

A practical approach is to allocate in proportion to each marketplace's share of recent sales, then keep a small unallocated reserve.

The percentages in the table are an example only. Use your own numbers. Holding back a reserve means you can top up whichever marketplace sells out first without re-preparing anything. For the sync side of this, see how sold stock sync helps keep quantities aligned after sales, and read our guide on preventing overselling across marketplaces.

Turning the trigger into a routine

A reorder point only works if someone checks it. Keep the routine small.

Step 1: Record available stock in one place

You need a single figure for total sellable stock per product. If you track inventory in a spreadsheet, keep one row per product with current available quantity, reorder point, lead time, and safety days. If you manage listings through a multi-marketplace panel such as Sellerbot, use its listing and sold-stock views to confirm what is still live on each marketplace before you compare it to your reorder point.

Step 2: Compare available stock to the reorder point

Mark each product as one of three states:

• Healthy: available stock well above the reorder point.
• Reorder now: available stock at or below the reorder point.
• Urgent: available stock below the lead-time demand alone, meaning you will likely run out before new stock arrives.

Step 3: Prepare the batch while stock still sells

Once a product hits the trigger, start sourcing and verification. Prepare the upload file using your bulk restock checklist so that field mapping, titles, and prices are checked before the upload, not during an emergency.

Step 4: Restock and confirm

After the upload, verify that the quantities and prices on each marketplace match your plan. Partial failures are easier to catch when you still have remaining stock selling, which is another benefit of restocking before zero. You can review the platforms Sellerbot supports to confirm which marketplaces your workflow covers.

Pricing interacts with reorder points

Stock level and price influence each other, so look at both when you review.

• Fast sell-through and low stock: you may be underpriced. Check price suggestions for comparable offers before deciding whether to hold price or raise it slightly.
• Slow sell-through and high stock: you may be overpriced, or the product demand has faded. Lower the reorder point or pause restocking instead of buying more.
• Low stock with a strong market position: consider raising price a little instead of racing to zero. Always keep your price floor in place, as covered in our net-payout price floor guide.

Suggestions from any tool should still go through your own review. A price signal tells you what the market looks like, not what your margin can support.

Common mistakes to avoid

• Using revenue instead of units. Reorder points are about quantity moving out the door. A price change can hide a volume change.
• Ignoring lead time. A reorder point without lead time is just a low-stock alert.
• Counting unlisted or reserved stock as available. Count only what you can actually deliver today.
• Never recalculating. Demand shifts after patches, promos, and seasons. Recalculate velocity at least weekly for your top products.
• Treating all marketplaces as one pool without allocation. The total can look healthy while the busiest marketplace is empty.
• Letting returned or disputed stock inflate the count. Quarantine questionable stock before it counts toward availability, as in our returned stock relisting workflow.

A quick reorder-point checklist

• Velocity calculated from a recent, appropriate window
• Lead time written down per product
• Safety days set by stock-out risk
• Reorder point = velocity × (lead time + safety days)
• Allocation by marketplace share plus a small reserve
• Weekly check of available stock against the trigger
• Batch prep starts at the trigger, not at zero
• Post-upload check of quantities and prices on each marketplace

Where Sellerbot fits

Reorder points are a planning method, and you can run them from a spreadsheet. The hard part is keeping the inputs accurate when stock is listed on five marketplaces. Sellerbot helps by managing listings and bulk restocks in one place, mapping fields to each marketplace, and syncing sold stock so your available quantity is easier to trust. You can see the panel in the preview or compare plans when you are ready to move your restock routine out of scattered tabs.

Start small: pick your three best-selling products, calculate their reorder points today, and see how many stock-outs you avoid over the next month.
