A customer portal and knowledge base where customers help themselves

Customers sign in with a link in their email, no password needed. They see their own tickets, ask a new question and first get articles from your knowledge base suggested. The knowledge base is public, in Dutch and English, and shows you what customers search for and cannot find.

  • Sign in with an email link, no password
  • Article suggestions with every new question
  • Insights into searches without results

Why customers keep emailing the same questions

A customer wants to know how to add a new user. They search your website, find a PDF from three years ago, and email support instead. Two days later they email again: "Did you get my question?" Because nowhere can they see whether it was picked up, by whom, and when to expect an answer.

On the other side sits your support team. It answers the same question about adding a user four times a week. The answer lives in a document on a shared drive, but customers cannot reach it. And the "did you get it" emails become tickets of their own.

So two things are needed. A place where customers follow their own questions, without another account and password they will forget anyway. And a knowledge base that is truly public, findable in Google, and that you keep current because you can see which articles are missing.

In Lumo both hang off your helpdesk. The customer portal shows each customer their own tickets with your team's replies. They never see internal notes. When they ask a new question, the portal first shows articles that look like it. Often that is enough, and if not, a ticket is created as usual.

You write the knowledge base in Lumo in Markdown, with categories and a version history. The insights tab shows what people search for most, what they search for without results and which articles do not help. That is your writing list for next week. How to set up a helpdesk including a knowledge base is covered in the guide set up a helpdesk.

How the customer portal works

The portal has its own address for your workspace. Customers do not need a password.

  1. Request a sign-in link

    The customer enters their email on the portal and gets a link by email. After confirming, they are in. A link that expired or was already used no longer works, and they request a new one.

  2. Their tickets

    They see their own tickets with status and the conversation with your team. Your replies show as coming from your team, theirs as their own.

  3. New question

    When they ask a new question, the portal first shows articles that look like it. If those do not help, they send the question and a ticket is created.

  4. Reply

    On an open ticket they send a reply. It lands in the ticket for your team.

  5. Mark as solved

    Once their question is answered, they mark the ticket as solved themselves. If they reply again later, your team picks it up again.

The knowledge base has its own public address for your workspace. You write articles in Markdown, with headings, lists and links, and group them into categories so customers reach the right topic quickly. Visitors search across all articles and can say whether each article was helpful.

An article has three statuses: draft, published and archived. Every change goes into the version history with its reason: created, edited, published, archived or restored. Restore brings back the text of an earlier version, while the current text stays in the history, so nothing is ever lost.

Each article can have a Dutch and an English version. You write the translation yourself, Lumo does not translate automatically. It takes a little more time, but you know exactly what it says. For the knowledge base as a whole you choose draft, reachable by its address but hidden from search engines, or published, which makes it findable in Google too.

  • Articles in Markdown with categories
  • Draft, published and archived
  • Version history with restore
  • A Dutch and an English version per article
Knowledge base in Lumo with categories, articles and a search field

A knowledge base without numbers turns into an archive within months. That is why the knowledge base in Lumo has an insights tab, over a period you choose.

It shows the number of searches and how many returned no result. It shows views and helpful votes. And it shows four lists. Most searched: what customers look for most. Searched without result: a missing article, and Lumo says so. Articles that do not help: those visitors mark as unhelpful. Most read: your key articles, which must always be current.

That makes upkeep a fixed routine instead of something you do when there is time left. Once a week you look at searches without results and give the top two topics an article. Every article that prevents a question is one ticket less in your helpdesk.

  • Searches and how many had no result
  • Views and helpful votes per article
  • Lists: most searched, no result, unhelpful, most read
  • Period of your choice
Ticket inbox in Lumo with tickets customers opened through the portal

In the portal a customer sees their own tickets. Your team's internal notes are never shown, not in the list and not in the conversation. If someone tries to open a ticket that is not theirs, they are told it does not exist or they have no access.

There are no passwords. Customers sign in with a link sent by email, which works once and is valid for a short time. That saves your team the forgotten-password questions, and saves the customer one more account.

Everything the customer does in the portal lands on the same person and organization in Lumo. A ticket they open sits with their organization and counts toward that customer's health score. After a ticket is solved, the portal asks how satisfied they are. So the account manager sees on the organization what is going on too. How Lumo handles permissions, roles and data is described under security and privacy.

  • Only the customer's own tickets
  • Internal notes never visible
  • Sign-in link by email, usable once
  • Tickets count toward customer health

An example: a SaaS company that gets fewer repeat questions

This is a made-up example to show the flow, not a customer case.

Say a SaaS company for scheduling software has 200 business customers. The support team of two answers the same questions every week. How do I add a user? How do I export the schedule? Why did my integration stop syncing? Every question came by email, and customers often emailed twice because they could not see whether anyone had picked it up.

The team sets up the knowledge base with five categories: Getting started, Users and roles, Schedules, Integrations and Billing. They start with twelve articles on the questions that come back most, in English first. For their Dutch customers they later write Dutch versions of the eight most read articles.

Then they switch on the customer portal and put the link under every support email and in the app's help menu. A customer who wants to add a user asks a new question, types it, and sees the matching article suggested. They read it and never send the question. Another customer has a question about a sync error that is not in the knowledge base, and sends it. They see their ticket in the portal, read the reply and mark it as solved themselves.

Every Monday team lead Ana looks at searches without results. In week one "single sign-on" is at the top. She writes an article explaining what the product supports, and a week later checks whether the term has dropped off the list.

How to set up the portal and knowledge base

  • Give the customer portal a title customers recognise, such as your company name plus Support.
  • Create four to six knowledge base categories based on your most asked questions.
  • Write articles first on the ten questions your team gets most.
  • Keep the knowledge base in draft, have a colleague read everything, then publish.
  • Decide which articles need a second language, starting with the most read.
  • Put the portal link under your support team's emails and on your contact page.
  • Plan a fixed weekly moment to go through searches without results.
  • Update or archive articles that do not help.

How the portal connects to the rest of Lumo

The customer portal is the customer side of your helpdesk. A question from the portal becomes a ticket with the same statuses, SLA targets and macros as a ticket from the mailbox. A conversation in live chat that you turn into a ticket shows up in the portal too.

Portal tickets count toward customer health, which your customer success team uses on the customer success page. And Lumo for customer service shows how portal, knowledge base, chat and tickets form one working day.

What to know about the portal and knowledge base

The knowledge base does not translate for you. You write the English or Dutch version of an article yourself, and languages other than Dutch and English are not available. So start with the most read articles and translate only those.

There is no AI chatbot that answers questions from the articles. Article suggestions for a new question search on the text the customer types. The portal is made for tickets. Invoices, contracts or orders of the customer are not in it. If you want to share those, write a knowledge base article that explains where the customer finds them.

Questions about the customer portal and knowledge base

Do customers need a password for the portal?

No. They enter their email and get a sign-in link by email. That link works once.

Can customers see my team's internal notes?

No, never. They only see the replies your team sends as a public reply.

Can a customer close a ticket themselves?

Yes. They mark it as solved. If they reply again afterwards, your team picks it up again.

Is the knowledge base findable in Google?

Yes, once you set it to published. As a draft it is only reachable by its address and hidden from search engines.

Which languages does the knowledge base support?

Dutch and English. You write both versions of an article yourself, there is no machine translation.

Can I restore an old version of an article?

Yes. In the version history you choose restore. The current text stays in the history as well.

How do I know which articles are missing?

The insights tab has a list of searches without results. Those are topics customers look for without finding an article.

Do portal questions become normal tickets?

Yes. They land in your ticket inbox with the same statuses, priorities and SLA targets as tickets from the mailbox.

Can I use the portal without the knowledge base?

Yes, but customers then get no article suggestions for a new question. A few articles on the most asked questions make it far more useful.
