End customer rating: making your sales partners' service quality visible through your customers' eyes – leadtributor Help Center

With end customer rating, you make visible how satisfied your end customers are with the work of your sales partners. Your end customers rate the sales partner who handled their lead with 1–5 stars and an optional comment. This closes the feedback loop around your leads: you see not only whether a lead was won, but also how your partner looked after the customer along the way.

This article uses a concrete example to show how to put end customer rating to work – from enabling it and feeding in the ratings to evaluating the results.

A usage example

Let's assume you are a manufacturer and distribute enquiries (leads) to your specialist retail partners. A partner accepts a lead, advises the end customer and closes the sale. A few days later you send – as you usually do – a short satisfaction survey to that end customer: “How satisfied were you with the advice from our partner?”

You feed the result of that survey into leadtributor automatically. From then on the rating appears directly on the relevant lead and flows into the partner's customer satisfaction. Over the months, this builds a solid picture of which partners look after your customers especially well – and where things are going wrong.

How does end customer rating work?

An end customer rating consists of 1–5 stars and an optional comment (up to 1000 characters).
It always refers to a specific lead handed over to a sales partner – and therefore to the partner who handled that lead.
The rating is not entered in the web app, but fed in via the leadtributor API. This lets you connect your existing survey or satisfaction process directly to leadtributor, without your end customers needing a leadtributor account.
Your authority as the lead owner is preserved: only you, as the lead owner, feed in ratings – the rated sales partner can neither set nor change their own rating.

Step 1: Enable end customer rating

The feature is disabled by default. Open the sales partner overview and switch to the Settings tab. In the Ratings section, turn on the End customer rating toggle.

Below it, the Visible to sales partners toggle lets you decide whether your partners may see their own end customer ratings:

on – the partner sees the rating and can understand their own service level.
off – the rating stays visible to you as the lead owner only (for internal steering).

Step 2: Collect ratings from your end customers

How you obtain the rating is entirely up to you – leadtributor does not prescribe a particular way. A typical approach is a short satisfaction survey by email after the lead is closed, a rating link on your website, or an existing CSAT/NPS tool. All that matters is that you end up with a star rating (1–5) and, optionally, a comment.

Step 3: Feed the rating into leadtributor

You transfer the finished rating to the relevant lead via the public leadtributor API. Technically, you use the endpoint PUT /commissions/{commissionId}/end-customer-rating and pass stars and, optionally, comment. The call is authenticated with your API key as the lead owner.

You obtain the commissionId – the identifier of the partner's handling of the lead – via the API or via WebHooks (for example, when a lead has been closed). This lets you embed the submission fully into your own automation workflow.

If you'd rather not write code, you can connect your survey process without any code through our integrations for Zapier or n8n. A complete reference of all endpoints and fields is available in the leadtributor Developer Portal. You create an API key in your account under Settings → Connectivity.

Note: for the API to accept a rating, end customer rating (Step 1) must be enabled. Otherwise the call is rejected.

Step 4: Evaluate the ratings

You can see the end customer ratings you've fed in two places:

On the Lead page of the respective lead – in the End customer rating card. A small eye icon indicates whether the rating is also visible to the sales partner.
In the partner dashboard in the Customer satisfaction section – there you see a partner's average rating over the selected period, aggregated across all ratings fed in.

Possible ways to use it

Compare partner quality objectively – recognise which partners delight your customers and which consistently underperform.
Develop weaker partners in a targeted way – low ratings with comments give you concrete starting points for partner conversations.
A 360° quality picture – combined with lead rating by sales partners, you see both sides: how your partner rates the lead quality and how the end customer rates the partner.
