# Receipt / Invoices

### How will payment be receipted? Is there a proof of payment?

When a payment is made:

1. Stripe will send a receipt of payment. 
2. FormSG will send a confirmation email with FormSG proof of payment.
   * **GST applicable**: Proof of payment will show "invoice", "inclusive of GST" and GST registration number. See [sample](https://go.gov.sg/formsg-guide-payments-invoice-example).
   * **Not GST applicable**: Proof of payment will show "receipt" and does not have GST related details.

Read the next item to find out more about differences between simplified tax invoice and regular tax invoice.

### Simplified tax invoices versus regular tax invoices?

For non-businesses, FormSG's receipts are sufficient.

If you are trying to invoice businesses, FormSG currently only supports simplified tax invoices.  

According to IRAS ([source](https://www.iras.gov.sg/taxes/goods-services-tax-\(gst\)/basics-of-gst/invoicing-price-display-and-record-keeping/invoicing-customers)), you may issue a simplified tax invoice instead of a regular tax invoice to a **business** if the **total amount payable does not exceed $1000**. A simplified tax invoice only requires the following information:

1. Supplier's name, address and GST registration number
2. Date of issue of invoice
3. An identifying number (e. g. invoice number)
4. Description of the goods or services supplied
5. Total amount payable including GST
6. A statement similar to "price payable includes GST"

A regular tax invoice, instead, must contain the following information:

In the meantime, if you need regular tax invoices, you may still use FormSG but must generate your own.

### How long is the retention period for receipts / invoices?

The receipts / invoices can be stored indefinitely for now.

### How do I modify the receipts / invoices?

GST registration number and business address can be modified in the form settings.

Organisation name, logo, colour, support email and number can be modified in Stripe. [Stripe dashboard features](/user-guides/advanced-guide/payments/stripe-dashboard-features.md#branding-and-public-details)

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
