Jersey Business Manager
Built for Jersey
Invoicing · GST · Payroll · ITIS · CER

Your accountant should be checking your books, not building them.

Jersey Business Manager works out your ITIS, your contributions and your quarterly figures, then hands you a summary your accountant can sign off in an hour instead of six.

Runs on your own computer. No account to create, and once you have the file it needs no internet: nothing you enter is ever uploaded.

Most of what you pay for is sorting, not thinking

Jersey accountants describe their own work as turning a pile of invoices, receipts and bank statements into an organised set of books. That pile is the expensive part - and it is the part you can hand over already done.

How it usually goes

  • Receipts in a drawer until the deadline
  • Someone else works out the ITIS every month
  • You find out about a deadline after it passed
  • Quarterly figures rebuilt from scratch each time
  • Billed for hours spent sorting your paperwork

How it goes with this

  • Entered once, when it happens
  • ITIS and contributions calculated as you go
  • Every deadline listed with its date
  • Quarterly figures always up to date
  • Your accountant reviews, signs and moves on

Three jobs, one program

Use the parts you need. If you have no staff, the payroll screen simply sits there unused.

GETTING PAID

Invoices and expenses

Professional invoices with your own details, numbered automatically, ready to print or save as PDF from your browser.

Getting started takes about ten minutes

Download

One file. Save it in a folder on your computer.

Open it

Double-click. It opens in Chrome or Edge. Nothing to install.

Use it free for 30 days

Everything works. Nothing is held back or limited.

Enter a licence code

If it earns its place, activate it. Your data stays exactly as it was.

What this does not do

It does not replace your accountant. Depending on your size and turnover, Revenue Jersey may require accounts prepared by a qualified accountant. What changes is what you hand them: organised figures instead of a shoebox.

It does not file anything for you. You copy the figures onto the real return on gov.je. You stay in control, and you stay responsible for what you submit.

It is not a shared system. One computer, one person at a time. If two people need to be in the books at once, this is not the right tool and I will tell you so.

Pricing

Paid once a year. Renewal includes the January update, when Jersey revises its rates and thresholds.

Questions people ask

Where is my information kept?

On your computer, and nowhere else. There is no account to create and no server holding your data. For payroll that matters: your staff's salaries and Social Security numbers never leave the building.

I already use QuickBooks or Xero. Why this?

Those are good at bookkeeping but they are not built for Jersey. They will not produce your CER or work out ITIS at each employee's effective rate. Many people here use both: one for the books, this for what Jersey specifically asks for.

What if the figures are wrong?

For your first two or three months, run it alongside however you do payroll now and compare. Once the numbers agree, you can rely on it. That is the sensible way to adopt any payroll system, and it is what I recommend to everyone.

An employee has not given me an ITIS notice.

Then you use 22%, the default rate Revenue Jersey requires until they provide one. The program prompts you for this.

What happens when the rates change in January?

Jersey revises its contribution limits and thresholds each year. Your renewal includes the updated version, so your calculations stay correct.

What if I stop paying?

The program stops letting you carry on, but nothing is deleted. Your records sit exactly where they are and come straight back if you activate again. You can also export everything at any time.

Download and try it

One file, about 150 KB. Save it somewhere sensible, double-click, and you have thirty days with everything working.

Free trial · no card, no account

Works on Windows with Chrome or Edge. Nothing is installed and nothing is sent anywhere.

After the thirty days

Nothing is deleted. Your invoices, staff and records sit exactly where they are, and come straight back when you enter a licence code.

If it has not earned its place, delete the file and that is the end of it. You owe nothing and there is nothing to cancel.

What happens when you click download

There is no installer and nothing is added to your computer's programs list. You get one file, and that file is the program.

1  IT LANDS IN DOWNLOADS

Your browser saves Jersey_Business_Manager.html to your Downloads folder, like any other file.

2  MOVE IT SOMEWHERE SAFE

Make a folder such as Documents\JerseyBusiness and put it there. Do not leave it in Downloads.

3  DOUBLE-CLICK IT

It opens in Chrome or Edge and you are working. Send a shortcut to your desktop so it is one click from then on.

Why the folder matters. Your records are saved alongside the program. If you leave it in Downloads and later empty that folder, you would lose both. Two minutes moving it now saves you that.
A couple of things you might see the first time.
Windows may ask whether to keep the file, because it was downloaded from the internet - choose keep. If your browser opens the file instead of saving it, right-click the download button and choose Save link as. And if it opens in a browser other than Chrome or Edge, right-click the file, choose Open with, pick Chrome or Edge and tick Always use this app.
Prefer a proper app icon? Install it instead

Same program, same private-on-your-machine data - but it sits on your desktop with its own icon and opens in its own window, like any installed app. No file to look after.

ON WINDOWS · CHROME OR EDGE

Open the app below, then click the small install icon at the right-hand end of the address bar (a screen with a downward arrow). Choose Install. It lands on your desktop and Start menu.

ON A MAC · SAFARI OR CHROME

Open the app, then in Safari choose File → Add to Dock, or in Chrome the install icon in the address bar. It appears in Launchpad.

Open the app to install it

Once installed it works offline and your thirty-day trial runs exactly the same. Nothing you enter ever leaves your computer.

Made in Jersey, by someone who needed it

I am Toni Molina. I run a small digital business in Jersey, and I built this because I was working out my own GST position and quarterly figures by hand and could not find anything made for this island.

If you want to see it before deciding, I will come to you and show you in fifteen minutes. No pressure and no obligation - if it is not right for your business I would rather tell you than sell it to you.
