This "Adding Postcode Cells Manually to Invoice Template" document was written for Excel Invoice Manager. If you are using Invoice Manager for Excel (namely Uniform Invoice Software), we recommend you to download ready-to-use templates from InvoicingTemplate.com.
Starting with 2.11.1015, Excel Invoice Manager offers a new option "ZIP/Postcode in separate cell". Without this option, "City State" and "Zip" fields are combined in one cell. If you check the " ZIP/Postcode in separate cell" option on the Settings window, ZIP or Postcode will use a separate cell. This feature might be helpful if you want to create UK or Canadian style invoice templates.
The name of the cell is oknWhoZipPostcode in the Bill To section; it is named Ship To section.
The invoice templates included in the versions prior to 2.11.1015 don´t have the oknWhoZipPostcode and oknShipZipPostcode cell names defined, so the " ZIP/Postcode in separate cell" option is invisible on the Settings window.
Here are the steps to define the required cell names manually in your existing template to make the "ZIP/Postcode in separate cell" option available.
