Frequently Asked Questions

Common questions about Karks CRM

Karks CRM is a great fit for any small business looking for a simple way to manage customers and send invoices.

With Karks CRM, you can email customer invoices directly within WordPress. You can customize the email to meet your needs, and there are merge tags for further personalization. Your message and a copy of the PDF will be sent to your customer. The plugin also uses the contact information already in a customer’s profile, saving you from repeatedly filling out the same address. The plugin uses the built-in WordPress email functionality. However, we recommend using a mail delivery service or sending via a separate SMTP server to avoid spam issues.

The plugin stores any customer contact and invoice data you input. That could include (but is not limited to) physical addresses, email addresses, contact names, phone numbers, and invoice details (pricing, services rendered, etc.) Karks CRM DOES NOT collect payment information by default. It doesn’t connect to any third-party payment gateways. Please do not use this plugin to store sensitive data!

By default, only site Administrators and users with the included custom CRM Manager roles can access customer data. Other users won’t be able to access the CRM.

You can use Karks CRM on any WordPress installation, whether locally or through a traditional web host. The plugin will work on any existing site. However, you could create a separate site just for your invoicing needs. As Karks CRM stores customer data, we recommend using the most secure hosting environment possible.

It’s all about security and ease of maintenance. Building connections to payment gateways or other services requires constant vigilance. That clashes with the simple approach of this plugin. Note: The plugin allows you to add custom payment links, which will appear as buttons on your invoices. You can also add payment instructions to your emails.
