Sliced Invoices & Contact Form 7


Imagine having a form on your website that allows your visitors to basically create their own quotes for you!

All you need to do once they have submitted the form is read the description of work they require and then set your pricing. All of their client data has already been captured and added to the quote.


Initial Setup

Once you have both plugins installed and activated, you simply need to create your Quote or Invoice Request form that contains the following fields:

Required Fields

  • sliced_client_name – the Client Name
  • sliced_client_email – the Client Email
  • sliced_title – becomes the Quote/Invoice title
  • sliced_quote_or_invoice – should be “quote” to create a quote, or “invoice” to create an invoice. For example:

    [hidden sliced_quote_or_invoice “invoice”]

If sliced_quote_or_invoice is not included in the form, then “quote” will be assumed by default.

Optional Fields

You can also add the following optional fields that will map to other Sliced Invoices fields for the quote:

  • sliced_client_business – the Client Business Name – recommended
  • sliced_client_address – the Client Address
  • sliced_client_extra – the Client Extra Info field
  • sliced_description – becomes the Quote/Invoice description – recommended

Line Items:

For line items, you can use the following tags. Just replace {X} with a number. For example sliced_line_item_1_title, sliced_line_item_2_title, etc.

  • sliced_line_item_{X}_qty – the quantity for line item #{X}
  • sliced_line_item_{X}_title – the title for line item #{X}
  • sliced_line_item_{X}_desc – the description for line item #{X}
  • sliced_line_item_{X}_amt – the amount for line item #{X}

Other Fields:

  • sliced_invoice_status – allows you to set the status of the invoice (unpaid, paid, etc.). Default is ‘draft’.
  • sliced_quote_status – allows you to set the status of the quote (accepted, declined, etc.). Default is ‘draft’.

NOTE: the names of the fields must match exactly as shown

See the FAQs for an example form.

You can also set up confirmations and notifications as per normal in the Contact Form 7 form settings. However if you want to send the quote or invoice automatically, add the following tag to your form:

[hidden sliced_quote_send "true"]

(for quotes)


[hidden sliced_invoice_send "true"]

(for invoices)

With the form setup and the fields mapped, you simply need to add the form shortcode to one of your pages. When a client fills in your Quote Request form, a new quote will automatically be created with all of their details added to the quote.

You then need to simply add the line items and pricing to the quote and send to the client.

If the email address that the client fills in is not already linked to a client, the plugin will automatically create a new client with this email. (Don’t worry, if the email address provided matches an existing client/user, it will not be modified for security reasons.)


  • Creating the Quote Request Form
  • Inserting the Quote Request Form into a page
  • The Quote Request Form on the front end of the site
  • The blank Quote that is created when a user fills in the form. You just need to add your pricing to the quote.


  1. Upload plugin to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress


An example form:

<p>Your Name (required)<br />
    [text* sliced_client_name] </p>

<p>Your Email (required)<br />
    [email* sliced_client_email] </p>

<p>Website (required)<br />
    [url* sliced_client_website] </p>

<p>Business Name (required)<br />
    [text* sliced_client_business] </p>

<p>Address<br />
    [textarea sliced_client_address] </p>

<p>Any extra Business info<br />
    [textarea sliced_client_extra] </p>

<p>Overview of work required (required)<br />
    [text* sliced_title] </p>

<p>Description of work required (required)<br />
    [textarea* sliced_description] </p>

<p>[submit "Send"]</p>

If you follow the instructions to the tee (including, using all of the required items "sliced_title") then this does work. And on top of that I've been able to edit some of the code of the plugin to allow me to tweak a few settings as well. Great work on an actually working integration plugin that's going to help me a lot. I've tried form integration for other invoice plugins and did not have much success if any at all. At least for the free versions. Thanks. Hope it gets even better with time.
