Client portals for contractors: how they work on site

How a client portal helps a contractor: site photos and updates in the right place, the latest version of every plan, and approvals you can still show months later.

A client portal gives a contractor one file per project: the photos and updates from that site, the latest version of every plan, and a record of who approved what and when. Ziggu brings those three together in one space in your own branding, so the back and forth about the site leaves the inbox and the group chat.

Key takeaways

  • A client portal like Ziggu gives a contractor one file per project, holding the communication, documents, tasks and approvals of that project and nothing else.
  • Site photos belong with an update, a report point or a document in a client portal, not in a group chat nobody can search three months later.
  • A client portal shows the latest version of every plan and specification, so a subcontractor does not keep building on last month’s drawing.
  • Approvals in a client portal are kept with a name and a date, so a contractor never has to defend a choice from memory.
  • A client portal the client opens himself turns the status question from a Friday evening phone call into something he checks on his own.

Is there a client portal for contractors with site photos and updates?

Yes. In a client portal, site photos land in three places, each with its own job: with an update that reaches everyone involved in that project, with a report point that carries an owner and a deadline, and with a document the client can still open years after handover.

The difference with a group chat is not the photo. It is what the photo is attached to. A photo in a chat is a photo. A photo on a report point is an agreement with a name and a deadline on it.

In Ziggu you write that update on site. The client gets a notification, opens his own file, and sees the photo next to the milestone it belongs to. Anyone joining later reads the series in order instead of scrolling a chat.

Marc Wagner, Owner and CEO of Polyform, on what is now called Client Updates: “Ziggu also offers a very useful tool, the news feed. You can use it to share photos of the construction with your customers. We didn’t share enough of those updates before Ziggu, because it was a cumbersome job, but now you only need a few clicks.” How that runs at Polyform is in the Polyform story.

Clients keep asking until they can find the answer themselves

A client portal removes the status question by letting the client look for himself: the milestones on his project, what is done, what comes next, and the answers to the questions every client asks.

A contractor’s client is usually one person building once in their life. They do not know what a progress statement is and would rather not ask. So they call.

You do not want to be the walking FAQ. You also do not want to be the contractor nobody hears from. A portal settles that by putting the answer somewhere they come and get it.

What changes compared to email and WhatsApp

The difference between email with a shared folder and a client portal is not a feature. It is where the truth sits. With email it is spread across the inboxes of everyone involved. With a portal it sits on the project.

WhatsApp is the hardest case, because it works. Until someone deletes a message, until a new subcontractor joins, or until you have to show three months later what was agreed.

The cost of the wrong channel never lands in the inbox either. It lands on site, on the day a crew stands waiting, or something goes in according to a drawing that is two weeks old.

SubjectEmail and WhatsAppClient portal
CommunicationSpread across inboxes and groupsConversations by topic, inside the project file
Site photosIn a chat, unfindable after a monthOn the milestone or report point they belong to
DocumentsVersions side by side, hunting through foldersLatest version on top, with who viewed it
ProgressA phone call, and an email when there is timeMilestones the client checks himself
ApprovalsVerbal on site, or somewhere in an emailWho approved what and when, on record
SubcontractorsForwarding them what they needTheir own access to what concerns them

The gain is not in any single row. It is that they all sit in the same place, so you stop having to remember where something was agreed.

Subcontractors work in the project without you playing postman

A client portal lets a contractor put partners straight into the project, with rights per party, so the electrician sees the drawing that concerns him and the client does not have to read along with everything.

A large part of a contractor’s day goes into forwarding. The kitchen fitter wants the plan the architect changed yesterday. The floor layer wants to know when the screed is dry. The client wants to know whether that is sorted now. Three messages, three channels, and you in the middle.

In Ziggu every partner has their own access to the project. What they may see is fixed in the project and is no longer negotiated by email. That means they work on the version that is there today, not on the one they were sent once.

Notifications follow the same logic. A partner does not get a message about everything happening in the project, but about the one thing that concerns them, one click away from the version that is there at that moment. That is usually the difference between a partner who opens the portal and a partner who waits for your call.

Ken Alleweireldt, Director at Volus, puts it small and concrete: “The electrician has access to the kitchen contractor’s documents, for example.” That is the moment you drop out of the chain yourself.

For a firm working with the same partners, that becomes a way of working after a few projects instead of an arrangement per site. What it means for studios and construction firms is on the Ziggu for architects and contractors page.

An approval you can still show three months later

A client portal puts choices to the client and keeps the answer with a name and a date, so variations and material choices stop being an argument after the fact.

The scenario is always the same. The client hesitates about the kitchen, you send a revised plan, they say yes on site, and three months later nobody remembers it the same way.

Variations rarely arrive at a convenient moment. They arrive while work is going on, usually verbally, and they are about money. A portal puts that question as a choice with a price and a consequence, and keeps the answer where the rest of the project already sits.

Under those approvals sits the log. Every action by every user is kept, and your client opens that log as easily as you do. It is not a file you keep on them: it is a record both of you can point at.

Frequently asked questions about client portals for contractors

Does a portal work with clients who are not digital?

Laura Callewaert, Interior Architect at Hoprom, saw both younger and older clients take to it immediately. The client installs nothing and gets an email as soon as something is waiting for them.

Is project data safe in a client portal?

Ziggu keeps project data encrypted server-side on Google Cloud in Belgium, backed up daily across two clouds and in at least two European locations. Access is set per project, every action in the project is written to the log, and the Ziggu team cannot open your data without a permission you grant from your own account.

How long before a construction firm is working in it?

You set up a first project and try it during the 14-day free trial, no credit card. Most of the time goes not into the software but into deciding which documents and milestones belong in every project by default.
