One secure login where your clients see their invoices, projects, documents and tickets, pay online and upload what you asked for — in your branding, at any hour, without a single email attachment.
A large share of the messages a business sends every week are not work. They are logistics: sending a copy of an invoice, confirming a payment, forwarding a document that was already sent, answering “where are we with this?” and asking again for the file you needed last Tuesday.
None of it requires a human. It requires access. When clients can see their own information whenever they want, most of those messages simply never get written.
The IDup client portal gives each client a secure login to exactly what concerns them: invoices with online payment, project status, shared documents, open tickets and a place to upload what you requested. It carries your branding, respects your permissions, and works on a phone at eleven at night when nobody in your office is awake.
All in IDup — one login, no silos.
Clients see their invoices, current and historical, and settle them online by card or bank transfer with one tap — which is the single biggest lever on how quickly you get paid.
Milestones, progress and deliverables visible to the client at the level of detail you choose, so “any update?” emails largely disappear and the relationship feels considerably more professional.
Contracts, reports and files shared through an encrypted portal rather than as email attachments — and clients can upload what you asked for into the right place instead of into your inbox.
The portal looks like your business, not like a piece of software, and granular permissions decide exactly what each client can see, download or do.

The most common reason an invoice is paid late is not unwillingness. It is friction: the invoice is a PDF in an email, paying it means opening a banking app and typing a reference, and that small effort is easy to postpone to a day that never comes.
In the portal the invoice and the payment are the same screen. One tap, card or bank transfer, done — and the payment is matched to the invoice and booked in your accounting automatically.
That combination of visibility and one-tap settlement measurably shortens the time between finishing the work and having the money, which for most small businesses matters more than any other single improvement.
An invitation with their own secure login — no shared passwords, no attachments.
Invoices, projects, documents and tickets, exactly as much as you choose to show.
Payments, uploads and status checks happen without anyone in your team being involved.

Clients do not want more communication from you. They want fewer open questions. Those are not the same thing, and confusing them is why so much customer communication feels like work for both sides.
A portal answers the routine questions permanently: what is the status, what did we agree, what have I paid, what do you still need from me. What remains are the conversations that actually deserve a person.
It also removes the most common security weakness in small businesses — confidential documents travelling as email attachments to whichever address someone happened to use — and replaces it with encrypted access that is logged and revocable.
One login, ein Preis – keine versteckten Zusatzkosten.
Yes. Permissions are granular, per client and per area, so a client sees their own invoices, projects and documents and nothing that belongs to anyone else.
Yes — logo, colours and domain presentation, so it feels like part of your business rather than a third-party tool your clients have to trust separately.
Yes, by card or bank transfer, and the payment is matched to the invoice and booked in your accounting automatically — no reconciliation, no confirmation email needed.
Yes, into the right place against the right project or request, which is far more reliable than asking for them by email and then searching your inbox for the reply.
Yes. Each client has their own login, access is encrypted and hosted on secure, GDPR-compliant servers worldwide, and every access is logged — which is considerably safer than a chain of email attachments.
Minutes. Invite your first client and they have access immediately — there is nothing for them to install and nothing for you to configure first.
