Just Invoice support

How to get Just Invoice doing what you need, and how to reach a person when it isn't.

Last updated 2 September 2026

Just Invoice has not launched yet

Just Invoice is still in development and is not on the App Store, so if you are here looking for a download, there is not one yet. This page is published ahead of the release so the support link works from the moment the app appears. Everything below describes how Just Invoice behaves at launch.

Contact us

Email support@mwds.digital. A person reads it. Tell us what you were doing, what you expected and what happened instead, and include your app version from Settings if you can — it makes the difference between a guess and a fix.

Getting set up

  • Enter your business name and country when you first open the app. Everything else can wait.
  • If you are registered for GST, add your state and your GSTIN in Settings. The state is what decides whether an invoice carries CGST and SGST or IGST.
  • Set your invoice prefix, starting number and zero padding in Settings before you raise your first invoice. Numbers are never reissued once used, so it is worth getting the series right at the start.

Why is my invoice showing IGST?

An invoice carries IGST when your state and the place of supply are different. If that is not what you expected, check the state on your own business in Settings and the place of supply on the customer. When you bill a registered business and the place of supply is missing, Just Invoice will not let you raise the invoice at all rather than guess — their input credit depends on getting it right.

Syncing between devices

  • Turn on iCloud sync in Settings. You will be asked to sign in with Apple, because sync needs an account to attach to.
  • Use the same Apple Account on every device.
  • Sync goes through your own private iCloud Drive. If a device cannot reach it, Just Invoice leaves what is already there alone rather than overwriting it.
  • Signing out turns sync off. Nothing on the device is deleted.

Backing up and moving devices

Settings has an Export for customers, invoices, expenses, income and products, and an Import that reads the same files back. Importing offers to merge — adding only records this device does not already have — or to replace everything. Export before you change devices, even if you use iCloud.

Refunds

Purchases are handled by Apple, not by us, so refunds go through Apple. Report a problem at reportaproblem.apple.com. If something in the app is at fault, email us as well and we will fix it.
