# Receipts
**{{variable.GTX Bold}}** enables the entry and allocation of customer payments using the Receipts module.
The Receipts module can be accessed by selecting **Main > Data Entry > Receipts** from the menu bar.

## Adding Receipts
**To add a new receipt:**
* Click **New Receipt** (right toolbar)
* Select the **Customer**
* Top-right shows **outstanding balance** and **ageing breakdown**
>>The term in the screenshot is Overdue Balance, if you want to define the terms in the screenshot like the other bold titles in this section. I defer to your more proficient knowledge of English but "ageing" breakdown sounds funny.
* Enter the **Amount Received**
* Enter **Merchant Fee** and **GST Amount**, if applicable
* Select the **Salesperson**
* Enter a **Comment**, if necessary
Use the **Line Details** list below to allocate the payment amount against the outstanding transactions, by entering the allocated amounts in the **Receipt Allocation** column.
:::(Warning) (Tip)
Use the **{{glossary.Sort}}** icon to arrange transactions by date order
:::
:::(Warning) (Tip)
To quickly enter the **entire payment amount** (or the remainder, if other allocations have already been entered), click in the relevant Receipt Allocation cell and press **Enter** on the keyboard.
:::
Once the unallocated balance is **$0**, click **Finalise** and confirm the receipt.
### Automatic Allocation
Payments can be automatically allocated by clicking **Auto Allocate** and selecting:
* **Auto:** Applies receipt and unallocated credits from oldest to newest
* **Oldest:** Allocates only the entered receipt amount from oldest first
* **Age Code:** Allocates within a specified ageing range
Confirm allocation and finalise the transaction.
## Unallocated Receipts
**If you are unsure which invoices to apply a payment to:**
* **[Enter the receipt](/gtx/docs/receipts#adding-receipts)** as usual
* Click **Finalise**
* When warned that an amount remains unallocated, select **Yes**
* Click the **Finalise** button
* Enter and confirm the **payment method**
The payment will be recorded against the customer's outstanding balance and remain unallocated for [future allocation](/gtx/docs/receipts#allocating-unallocated-receipts).
### Allocating Unallocated Receipts
**To allocate an unallocated payment:**
* Select the **Customer**
* Enable **Show All Open Entries** (top of Line Details list)
* Identify the payment with a **non-zero balance**
* Enter the payment amount in the **Receipt Allocation** field
* **Allocate** it against the appropriate invoices
If the full amount is allocated, both the invoice and payment will show **$0** balances.
