Chatref connects your invoicing help docs to an embeddable chat widget, so customers get instant answers about payment terms, invoice setup, and common errors directly on your site. You point the widget at your invoicing knowledge base, and it resolves billing questions from your own content.

What connects to what

Chatref’s website widget draws answers from a knowledge base you build. You upload your invoicing software’s help articles, setup guides, payment FAQs, and refund policies. The widget then retrieves answers from that content when someone asks a question on your site.

The integration has three touchpoints:

  • Your invoicing help content: PDFs, URLs, or plain text you add to Chatref.
  • The widget snippet: One line of JavaScript you place on your invoicing software’s web pages.
  • The user’s browser: Where the widget appears and where the question is answered.

No API calls or custom code between your invoicing system and Chatref are required. The widget simply references the knowledge base you’ve trained it on.

How to set it up

  1. Gather your invoicing help materials – Collect all the documents that explain how to use your invoicing software: setup instructions, payment gateway configuration, invoice template customization, recurring billing, and troubleshooting guides. Common formats like PDFs, help center URLs, and plain text work.

  2. Add them to Chatref – In your Chatref dashboard, upload those materials to create a knowledge base. The system processes them automatically and learns your invoicing content. You can point it at your existing help center or upload files directly.

  3. Configure your widget – From the Chatref agent settings, copy the widget snippet. It’s a small block of JavaScript. You can adjust the widget’s primary color and branding to match your invoicing software’s look.

  4. Place the snippet on your site – Paste the snippet into your invoicing software’s website, ideally just before the closing </body> tag. If your invoicing platform is a SaaS product (like Invoicing Software), you can add the snippet to your app’s main layout so it appears on every page where users might need help.

  5. Test it – Open your site, trigger the widget, and ask a few invoicing-related questions: “How do I add a payment gateway?” or “Why was my invoice rejected?” Confirm the answers accurately reflect your own docs.

That’s it. No further integration steps are needed. The widget starts responding from your invoicing knowledge base immediately.

What users see

Users visiting your invoicing software website see a chat bubble in the corner of their screen. When they click it, a chat window opens with a greeting. They can type any invoicing payment question, such as:

  • “How do I set up Stripe for invoice payments?”
  • “What are the payment terms for net-30?”
  • “Why didn’t my client receive the invoice email?”

Answers come from the docs you uploaded. They appear in-line, often with a source reference, so users know the information is from your own help center, not a generic web search. No dead-end links; the answer is right there in the chat.

If a question exceeds what the knowledge base covers or requires human intervention, the widget can hand off the conversation to your support team, preserving the full chat history.

Troubleshooting

Widget doesn’t appear on the site

  • Check that the snippet is placed correctly and that your site’s domain matches the allowlist in Chatref’s widget settings.
  • Ensure no browser extensions or ad blockers are suppressing the widget.

Answers don’t match your invoicing docs

  • Verify that the knowledge base includes the relevant documents. If a guide on payment gateways is missing, upload it.
  • Review the uploaded content for accuracy. Outdated or incomplete docs produce incomplete answers.

Widget answers about topics outside invoicing

  • This can happen if the knowledge base contains unrelated material. Remove or exclude non-invoicing documents from the agent’s training set.

Invoicing payment solutions problems persist

  • If users still report issues, check whether the knowledge base addresses common failure modes: payment gateway errors, invoice formatting conflicts, or regional payment method limitations. The widget answers what the docs cover – gaps in the docs create gaps in the support.
