Margin needs costs, and costs come from more places than the catalog: a purchase price per product, the commission a marketplace took, the label you paid the carrier, the fee your payment provider kept. The Costs page shows how much of that WISEPIM knows per store, and gives you three ways to fill the gaps. **What this page enables:** [Margin](https://docs.wisepim.com/en/analytics/margin.md) stops reading **Needs product costs** and starts showing margin after product costs and after selling costs, on orders you already have, with costs you can trace back to an import. **Where to find it:** open **Analytics**, expand the **Data & setup** group in the sidebar and click **Costs**. The page has two tabs: **Costs** and **bol invoices**. The **Add product costs** and **Import payment and carrier fees** steps on the [Today](https://docs.wisepim.com/en/analytics/today.md) page land here. ![WISEPIM Costs page with cost coverage per store, products without a cost, imported cost batches and the cost file import](https://mintcdn.com/swiftsyncai/e5lHCbnPIlrrYMyG/images/marketing-screenshots/analytics/order-evidence-costs-light-branded.webp?fit=max\&auto=format\&n=e5lHCbnPIlrrYMyG\&q=85\&s=41286f9c338178fbd19a3c44bc1ef2d0) > [!NOTE] > > Posting costs needs permission to manage settings. Coverage counts orders, never money: a store reads **N of N orders** covered for each cost kind, so you always know how much of Margin rests on known costs. Cost coverage looks at one period, so there is nothing to compare. ## Cost coverage The **Cost coverage** table has one row per cost kind and one column per store: **Marketplace commission**, **Payment fees**, **Shipping labels**, **Return labels**, **Fulfilment**, **Return handling** and **Advertising**. Each cell reads **N of N orders**, the gap **Missing `{range}`** when days have no postings, and **Last posted `{time}`**. ## Products sold with no recorded cost Below the table, **N products sold with no recorded cost** lists the products Margin cannot price. Two fixes: * **Set cost price** writes a cost price into the catalog. It applies to orders imported from now on, as an estimate (≈). Past orders don't change. * **Import purchase prices for these orders** posts your purchase price per product to the order lines sold in the dates you choose. Margin uses it instead of the catalog estimate. ### Import purchase prices **1. Prepare the file** One row per SKU with the purchase price, its currency, and the date range it applies to. A file may match up to 5,000 order lines; split larger files by date range. **2. Preview** Upload it under **Import purchase prices**. The preview reads **N order lines in N orders get a cost. N catalog estimates are replaced.** Rows that cannot be posted say why: **SKU not found in your catalog**, **More than one product has this SKU**, **These lines already have a non-estimated cost**, **Dates overlap with another row for this SKU**, or **Some orders are in another currency, so we skipped them**. **3. Post** Click **Post purchase prices**. The confirmation ends with **Reports need an update.** Run **Update reports** under [Analytics settings](https://docs.wisepim.com/en/analytics/analytics-settings.md) for the period. > [!WARNING] > > Posted costs can't be removed from here. Importing again for the same lines replaces them only if they were estimates. An exact cost is never overwritten by a later import. ## Imported costs **Imported costs** lists every batch you posted, grouped by source account and day: **Source account**, **Store**, **Costs dated**, **Rows** and **Total**. Rows posted before are reused, not added twice, so re-importing the same file is safe. ## Import a cost file Fees and carrier costs come in as a CSV from the marketplace, payment provider or carrier. **1. Which store is this file for?** Pick the store. Costs apply to the store and account you pick. **2. What kind of cost is it?** Choose **Marketplace and payment fees** or **Carrier and fulfilment costs**. **3. Add the file** **Choose a CSV file**, or paste the rows. Enter the **Source account** the file comes from, for this store. **4. Check the file format** One row per cost: order number (or order ID), amount, currency and date. Amounts may use a comma or a point. The technical format is a UTF-8 CSV with commas, 1 to 500 rows, up to 250 KB, with the columns `source_id`, `charge_subject`, `order_id`, `kind`, `amount`, `currency` and `occurred_at`. Kinds for fees are `marketplace_fee`, `payment_fee` and `compensation`; for carriers `shipping`, `fulfilment`, `return_handling` and `compensation`. Negative amounts are credits. **5. Preview and post** Click **Preview costs**. The **Check the costs** step reads **N rows: N new, N already posted.** with totals per currency for all rows, including ones already posted. Rows that did not match say **Order number not found in this store**, **More than one order has this number** or **This order belongs to another store**. Then click **Post costs**. > [!NOTE] > > Posted costs can't be removed from here. Rows posted before are reused, not added twice, and your store stays as it is. The preview you confirm is valid for a short while; if orders or settings change in between, WISEPIM asks you to preview again. ## bol invoices ![WISEPIM bol invoices tab with the invoice form, the reviewed invoice lines and the invoice check](https://mintcdn.com/swiftsyncai/e5lHCbnPIlrrYMyG/images/marketing-screenshots/analytics/order-evidence-bol-invoices-light-branded.webp?fit=max\&auto=format\&n=e5lHCbnPIlrrYMyG\&q=85\&s=dcce3d57a717f8f12b5a5ebed7b156ea) bol sends order lines but no order amounts, and its commission and fees arrive on an invoice. The **bol invoices** tab reads bol's commission and fees from the invoice and links them to your bol orders. You review a preview before anything is posted. **1. Pick the bol store** Choose the **bol store**. You need a connected bol store first, because invoice lines link to bol orders. **2. Describe the invoice** Set the **Cost type** (**Marketplace and payment fees** or **Carrier and fulfilment costs**), the **Invoice number** and your **bol customer number** as it appears on the invoice. **3. Paste the invoice JSON** Paste the **Invoice details (from the bol API)** and the **Invoice specification (from the bol API)** exactly as the bol Retailer API returns them, up to 500 rows. Tick **This specification includes every page of the invoice.** **4. Set the posting date** Enter the **Posting date** with a UTC offset. Recommended: the invoice date, so costs land in the month bol billed them. The date is never inferred. **5. Review and post** Click **Review invoice**. Under **Invoice lines**, each line is **Can be posted**, **Left out** or **Unknown line type**, and the **Invoice check** reads **Adds up** or **Can't tell**. Then click **Post costs**. Only costs that add up and link to a bol order number can be posted. Other lines are left out, with the reason shown: **No bol order number**, **Order numbers conflict**, **Sales, not a cost**, **Cost type not supported**, **Line doesn't add up**, **No single matching order in this store** or **Amount has too many decimals**. > [!NOTE] > > Commission is posted as a marketplace fee, shipment labels as shipping, pick and pack as fulfilment, and return labels as return handling. VAT is left out and bol's signs are kept, so a credit stays negative. Posted invoice costs are as final as any other posted cost. ## Act on what you find > **Margin after product costs is unknown on most orders** > > Look at **N products sold with no recorded cost**. For orders you already have, use **Import purchase prices for these orders**; a catalog **Set cost price** only helps from the next import on. Run **Update reports** afterwards. > **Margin after selling costs never appears** > > It needs every selling cost known. Check **Cost coverage** for the store: a kind at **0 of N orders** or a **Missing `{range}`** gap keeps the full margin unknown. Import the fee or carrier file for those days, or the bol invoice for a bol store. > **A cost file preview says every row is already posted** > > You imported this file before. Nothing is added twice, so you can close the preview. If the amounts changed, the only rows a re-import replaces are catalog estimates. > **A bol invoice line reads No single matching order in this store** > > The order number on the invoice does not match exactly one imported bol order in the store you picked. Check that the right **bol store** is selected and that the order was imported, under [Data health](https://docs.wisepim.com/en/analytics/data-health.md). Lines that still do not match stay out; they cannot be posted by hand. ## Related > **[Margin](https://docs.wisepim.com/en/analytics/margin.md)** > > The ladder these costs feed, from product costs to marketing. > **[Analytics settings](https://docs.wisepim.com/en/analytics/analytics-settings.md)** > > The cost currency and the report update that picks up new costs. > **[Data health](https://docs.wisepim.com/en/analytics/data-health.md)** > > See posted fees and carrier costs in the part-by-part check. > **[Supported Platforms](https://docs.wisepim.com/en/integrations/supported-platforms.md)** > > Connect the bol store that invoice lines link to.
