SSmartWerk

Work with your freelancer clients without taking over their books

Clients & sales

Invite your ZZP clients. They invoice in SmartWerk and you receive their quarterly package (invoices, receipts, VAT boxes, CSV for Exact, Twinfield or Moneybird) in one inbox. Without the client’s password.

Start for freeView pricing

Start free, no credit card needed.

Client portalShare quotes, contracts, invoices and project information with your client
01

What is it?

The bookkeeper portal is a free inbox for offices where you receive the packages of your ZZP clients.

02

Who is it for?

For bookkeepers and accountancy offices with freelance clients who now chase PDFs, receipts and emails to get to the figures.

03

What problem does it solve?

Every quarter the same chase: a missing receipt, an invoice in an email, an export in another format. A structured package per period saves office time.

What you get

01

One inbox for all your clients

Every client package under one login. You preview the VAT boxes without opening the ZIP.

How it works in SmartWerk

  1. 1

    Create a free bookkeeper account

    Use your office email address.

  2. 2

    Invite your ZZP clients

    They connect to your portal.

  3. 3

    Receive the quarter package

    Review it in the portal, ask for clarification or download the ZIP.

  4. 4

    Process it in your own package

    Import the CSV into Exact, Twinfield or Moneybird.

What you can do

The portal is the mailroom, not the bookkeeping: the client keeps invoicing in SmartWerk, you book in your own package.

  • Multi-client inbox

    Packages from all your clients in one place.

  • VAT boxes up front

    Look at VAT boxes 1a to 5g without opening the ZIP.

  • Request clarification

    Ask for a missing document; the client gets an email.

  • Import files

    CSV for Moneybird, Exact and Twinfield in the ZIP.

  • No password sharing

    You have your own login and see only what the client shares.

Frequently asked questions

Does the portal cost my office anything?

No. The bookkeeper portal is free for the office.

Does SmartWerk replace Exact, Twinfield or Moneybird?

No. SmartWerk is the freelancer’s administration (invoices, contracts, export). You stay in your own accounting package; the ZIP contains import files.

Can I correct the client’s invoices myself?

No. The client stays the owner of their data and corrects it themselves. You request clarification through the portal.

Does the client have to share their password?

No. You have your own free login and see only shared packages.

What it does not do

  • You only see what the client shares: no live access to their administration and no shared password.
  • SmartWerk does not file VAT returns and does not replace Exact, Twinfield or Moneybird.
  • You cannot correct the client’s invoices yourself; the client corrects them in SmartWerk.
