Applies to: Singapore only · QashierHQ and Qashier POS · Invoice Management add-on · QashierPay online card payments.

Before you start

Your business is in Singapore. The online payment setting is not available in other markets.
Invoice Management is turned on for your store. If Invoice Management is locked in your QashierHQ side menu, turn it on in Qashier Marketplace (see How to Add Features and Manage Your Plan in Qashier Marketplace (QashierHQ)) or contact Qashier support.
Your QashierPay payment services application is approved and online card payments are active for the store. See [SG/MY] How to Apply for QashierPay Payment Services in QashierHQ.
The customer is saved as a member with a valid email address. Without an email, no payment link can be sent. See How to Add (Register) a New Customer in Qashier POS.

Step 1: Apply for payment services

In QashierHQ, open Payment Management at the bottom of the side menu.
Under Apply for Payment Services Now, choose Continue Application via Singpass (Myinfo Business) or Apply Manually, and complete the application.
Wait for approval. Once approved, the page shows Your payment account is all set up!
In the Payment methods in your stores table, mark the card payment methods for your store.

Your online payment rates are listed under Payment methods rate details on the Payment Management page.

Step 2: Turn on online payment for invoices

In QashierHQ, go to Sales Channels > Invoice Management.
Select your store.
Turn on Allow customer to pay online at the top right.

Step 3: Create and send the invoice

On Qashier POS

Create the invoice for a member. See How to Create an Invoice in Qashier POS (Full Payment, Deposit or No Deposit).
When the POS shows "Invoice will be sent to [email], please confirm.", tap Confirm. The invoice email with the payment link goes to that address.

In QashierHQ (use hq.qashier.com in a web browser; Create Invoice is not available in the QashierHQ mobile app)

In Invoice Management, click Create Invoice and fill in the invoice. See How to Create and Send an Invoice in QashierHQ.
In the preview, click Confirm, then click Continue. You can't edit the invoice after this.
Click Send Customer Email, then click Confirm. The invoice and payment link are emailed to the customer. QashierHQ does not send it until you do this.

To send the email again later, open the invoice in Invoice Management, click Generate Invoice PDF, then click Resend Email.

What your customer pays through the link

Where the invoice was created	No deposit	Deposit required
Qashier POS	The link is for the full amount.	The deposit is paid on the POS. The link is for the remaining amount only.
QashierHQ	The link is for the full amount.	If the deposit wasn't paid on the POS, the customer can pay the deposit through the link. After that, the same link (refresh the page first) shows the remaining balance.

What you should see

When the customer has paid the full amount online, the invoice status in Invoice Management changes to Fully Paid automatically.
