Invoice Template Sample - Using Handwriting Signature in Your Invoices
Do you want to use your handwriting signature in your invoices? It´s easy to implement in Excel Invoice Manager, the billing software/invoice software program based on Microsoft Excel.
The principle is very simple: create an image containing your handwriting signature, and then add it to your invoice template. Of course, you only need to do all the customization work once - after adding the signature, all the invoices you create will include the signature.
Here are the detailed steps for customizing the invoice template.
- Prepare your handwriting signature in a format supported by Microsoft Excel, such as JPG or GIF format.
- Copy the standard invoice template (INVOICE.xls) or your customized version, name the new file HandwritingSignature.xls.
- Open the HandwritingSignature.xls invoice template in Microsoft Excel.
- Unprotect the Invoice worksheet by clicking Excel menu Tools -> Protection -> Unprotect Sheet.
- Switch the invoice template into design mode by clicking the Design Mode
button on the Control Toolbox toolbar. If the
Control Toolbox toolbar is not displayed,
click Excel menu View -> Toolbars
-> Control Toolbox.
In design mode, Excel Invoice Manager does not react to the click events on the ActiveX objects, allowing you to move, resize, add or delete ActiveX objects in the invoice template.
- Click the Image button on the Control Toolbox
toolbar. Click the location where you want to place the signature. An image object is added.

(Click to enlarge) - Right click the newly added image object; click the Properties command on the menu.
- In the Properties box,
enter oknWidget_signature in the Name
property. When you extract/email an invoice, all ActiveX objects will be removed from the
extracted invoice, except those with the oknWidget_ or
oknUser_ prefix in their names. For example,
the Save As New Customer button will be removed from the
extracted invoices, but the LOGO image will be leaved there. To make sure your signature image
is included in the extracted invoices, it must have a "oknWidget_"
or "oknUser_" prefix in its name.

- Browse to and click the Picture property. Click
the "..." button near the property. This opens the Load Picture
dialog box. Select and open your signature image file.

- If you prefer, you can also add a text label near the signature image, such as "Signature:".
