Quick answer
Blinkit's inventory charges sit in section C of the payout: upfront storage when stock goes in, storage (aging) charges on stock that sits too long, recall charges when you take stock back, and courier charges, each with its own GST line. They are charged on stock, not on sales, so a slow item can cost more in storage than it earns. Divide each item's storage, aging and recall charges by the units it sold in the cycle to see the real cost per unit, then send smaller quantities of slow items and recall before aging grows.
Commission is easy to see because it scales with sales. Storage is easy to miss: it is charged in a separate workbook, on stock rather than orders, and it keeps growing on items that do not move. This guide explains each charge, shows how to put a per-unit cost on it, and lists ways to keep it down. It does not quote Blinkit's rates, which differ by seller and change; use the figures on your own sheets.
The four inventory charges
| Line | Name on the sheet | When it is charged | What drives it |
|---|
| C1 | Upfront storage charge | When stock is received at the warehouse | Quantity you send in |
| C2 | Recall charge | When you ask for stock back | Quantity recalled |
| C3 | Storage charge (aging) | On stock that stays beyond the allowed period, after reversals | Slow-moving stock and time |
| C4 | Courier charge | Courier costs billed to you | Shipments |

Worked example: storage cost per unit (illustrative numbers)
| Fast item | Slow item |
|---|
| Units sold this cycle | 400 | 20 |
| Upfront + aging + recall charges (before GST) | ₹800 | ₹600 |
| Storage cost per unit sold | ₹2 | ₹30 |
| Margin per unit before storage | ₹12 | ₹25 |
| Margin per unit after storage | ₹10 | −₹5 |
The figures are made up to show the method; to model your own item, use the free Blinkit payout calculator. The slow item looks better on margin but loses money once storage is spread over the few units it sells. Run this per item every cycle; the item-level view is in profit per item on Blinkit, Zepto and Instamart.
Checklist: how to cut storage and aging
| Step | What to do |
|---|
| 1 | Find the items with the highest storage cost per unit sold (charges ÷ units sold). |
| 2 | Send slow items in smaller quantities, more often, matched to their sales. |
| 3 | Watch stock age; recall or run an offer before the aging charge starts or grows, comparing the recall charge with the expected aging charge. |
| 4 | Check the inventory sheets for stock you already recalled or that was lost; raise a ticket for charges on it. |
| 5 | Claim the GST on these charges as input credit when the invoices carry your GSTIN. |
| 6 | Use reorder points so you do not overstock: stock reorder calculator. More on slow stock: how to reduce dead stock and inventory turnover ratio. |
Doing it without spreadsheets
RichPOS Marketplace Accounts reads Blinkit's payout workbooks, recomputes the Payout Breakup from the detail sheets and flags any line that does not match, shows profit per item after Blinkit's charges, posts the cycle to your books, keeps a GST input credit register and exports your LP–SP debit notes for GSTR-1. Blinkit is supported today; Amazon and Flipkart are planned. Item profit shows each item's share of the charges, so slow items stand out. See Marketplace Accounts for Blinkit sellers.
