Step 2: Create Sales Invoice in BigSeller
-
Once the invoicing information is set up, BigSeller will sync order data from the current and previous months, including manual orders, messenger orders, and POS retail orders that have been shipped or completed. These orders will automatically be added to the [To Push] list.
-
For future orders, when the order status is New Order, In Process, To Pickup, Shipped, or Completed, the orders will automatically be added to the [To Push] list.
Step 3: Edit and Push the Sales Invoice
You can edit basic information, supplier information, buyer information, and item information.
- Seller Information: Select the seller company, and the system will automatically populate the details from the invoicing page.
- Buyer Information: If the customer's Malaysian invoicing details are available in BigSeller's Marketing > Customer Manage > Customer List module, they will be auto-filled. Otherwise, you'll need to enter them manually.
- Product Information: Click Sync Product Info to retrieve the product details from the order. You can edit or remove products as needed.
1. After clicking Save, the invoice will remain in the To Push list.
2. After clicking Save & Push, the invoice will enter the Pushing status. If the push is successful, the status will change to Push Successfully.
3. If the push fails, the status will be updated to Push Failed, and you can retry pushing the invoice.
3. How to Merge and Push Invoices
If your customer requires an invoice for the order, you must enter buyer information for each one. However, if the purpose is simply to submit data to the Malaysian tax authorities, you can merge multiple orders into a single consolidated invoice.
1. The currency of the selected orders must be the same if the invoices are merged.
2. When merging invoices, you do not need to enter the buyer's information. The system will automatically use General Public as the default company name.
