Frequently asked questions

Do I need to install an app?+

No. Use the LINE you already have: add the Aim Expense LINE Official Account as a friend, then send receipt photos or type entries in chat. Overview work such as approvals, reports and document issuing is done on the web from any device.

Where is our business data stored?+

In the Google Sheet and Google Drive of the Google account you connect. The system writes every entry and document there. We keep no copy of your business data on our servers, only your user account and subscription details.

Can a business that is not VAT-registered use it?+

Yes. Set the company to "not VAT-registered" and the system issues quotations, billing notes and receipts without a VAT line and hides the tax-invoice menu. When you register for VAT later, switch it on instantly.

Can it issue tax invoices and withholding certificates?+

Yes. Tax invoices get sequential numbers with the customer's branch details. Withholding certificates are printed onto the Revenue Department's 50 Tawi form using the actual payment date, and the system prepares monthly PND 3 and PND 53 summaries. You file them with the Revenue Department yourself.

Does it work for freelancers and individuals?+

Yes. Choose the individual account type and the menus adapt to logging income and expenses and keeping the withholding certificates your clients issue, for personal income tax filing. You can also add a company to the same account depending on your plan.

Do I lose my data if I cancel?+

No. The Google Sheet and Drive files have been yours from the start, so after cancelling you can still open, download or keep using them. Your account in our system is deleted on request.
