[Back](./) # How do I import invoices into Zoho Books? **Prerequisites:** * You can only import files in **CSV**, **TSV**, and **XLS** formats. * The file size must not exceed **10 MB**. To import bills into Zoho Books: * Log in to your Zoho Books organisation. * Go to _Sales_ on the left sidebar, and select **Invoices**. * Click the _More_ icon in the top right corner, and select **Import Invoices** from the dropdown. * In the _Import_ page, click **Choose File** and select the file you want to import. * After you select the file, under the _Configure_ tab, fill in the following fields: * **Character Encoding:** The default is **UTF-8 (Unicode)**. Ensure you select the correct encoding based on your file. * **Link Invoices to its corresponding Sales Orders:** Check this to map the _Sales Order_ field with the appropriate column containing the _Sales Order Number_ in the next page. * **Map the customer’s addresses in the import file to their customer record in Zoho Books:** Check this option to match customers in the import file with existing records in Zoho Books using their name. If a match is found, the address from the invoice will be added to that customer’s record. If no match is found, a new customer record will be created with the address from the import file. **Insight:** If your file is in a different format, use an online or offline converter to convert it to a supported format (**CSV**, **TSV**, or **XLSX**). * Go to the **Sales** module on the left sidebar. * Select **Invoices**. * Click the **More** icon on the top right corner of the page. * Select **Import Invoices**. * Click the **Choose File** button under **Upload file** and upload the file from your computer. * Click **Next**. * In the _Map Fields_ tab: * **Default Date Formats:** The default _Date Format_ is **Select** format at field level and _Decimal Format_ will be **1234567.89**. Click **Edit** to customise them if required. * Map the fields based on your requirements. Click **Save these selections for use during future imports** if you want to reuse the mapped fields for future imports. * Click **Next**. * Then, in the _Preview_ page, review the fields you mapped, and click **Import**. Now, the file containing the invoices will be imported into Zoho Books.
