Invoices, GST and payroll for your Jersey business. All in one place.

Jersey Business Manager (JBM) is a program for Jersey businesses that makes GST invoices, records sales and expenses, works out the figures for the GST return box by box, and prepares staff pay with ITIS and Class 1 contributions. It runs on your own computer, nothing you enter is uploaded, and it does not file anything for you. It is made in Jersey by Toni Molina.

There are two annual licences: Sole trader at £180 a year (£15 a month billed annually) and Business at £420 a year (£35 a month billed annually, with payroll). The first 90 days are free, with no card and no account. Licences are paid manually by written order and do not renew automatically.

You install it once from your browser, like an app, and open it from its own icon on your desktop or Home Screen. It works without an internet connection after that. The steps take about ten minutes and are shown below.

Yes. On an iPhone or iPad, open the app in Safari, tap Share, then Add to Home Screen. On Android, open it in Chrome and choose Install app. The screens, invoices and payslips are laid out for a smaller display, and the licence terms apply to the device you use. Your records stay on that phone or tablet and do not sync with your computer, so use Export backup regularly and Import to move them. Windows and Mac are the fully tested setups, and typing a lot of figures is easier on a keyboard.

When you open JBM online, it checks for a new version. If there is one, a bar appears at the top of the program with an Update now button. It saves your work first. Changes that affect rates or rules are marked as important until you update.

No. JBM prepares the figures and the summaries. You check them and file on the official gov.je pages yourself, so you always see exactly what you send.

Yes. The accountant report puts your totals, quarters, GST position and expenses on one sheet, so your accountant can start from tidy records. It does not replace their own checks.

It depends on what you do, not on your trade. It is intended for Jersey service businesses that send invoices and record expenses. Payroll fits only the pay arrangements listed in the suitability section, without pension deductions or special gross-pay adjustments. If you mostly sell over the counter, need stock control or use special GST schemes, it does not. The list above has the full picture, and the free trial comes with two example companies to try.

Your business records are stored in this browser profile on your computer; the app does not upload those records. The website and program files are still delivered over the internet. Browser storage is not encrypted, so protect the Windows account and keep separate backups.

Yes. JBM keeps your invoices, expenses, GST return figures and supported payroll cases on your own computer. It does not connect to other accounting software, fetch ITIS rates or submit returns. Compare its figures with your current process before you rely on them.

Run supported payroll cases alongside your current process and compare each pay run. Matching for a few months does not validate different pay patterns, changed ITIS rates, incomplete records or special tax circumstances. Keep checking the rate and source records every payday. JBM does not replace official guidance or professional review.

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

Renewal gives access to the current JBM release and its listed rate updates. Changes can take effect on different dates during the year. JBM does not retrieve employees’ ITIS rates, and an update cannot confirm that every case or record is correct. Check the effective date and official source for each period.

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.
