Function #49: Manage varying installment payments using Zoho Books
.
Hello everyone, and welcome back to our series!
Last week, we discussed automating the collection of fixed installment payments in Zoho Books. But what if your payment structure involves charging varying percentages of the invoice total as installments? We've got you covered with a solution—a Custom Button that simplifies the process.
Let's consider an example where Mr. John Hector is availing the services of Zylker Designs to build a website for his new business. The total project cost is $5,000 and is divided into the following milestones:
Initial Discussion: 10%
Design Phase: 30%
Development Phase: 40%
Final Delivery and Testing: 20%
Let's see how this payment structure can be handled in Zoho Books using a Custom Button.
First, Zylker Designs should create a sale invoice of $5,000 in their Zoho Books organization. When it's time to bill for a milestone, they can click the Custom Button and input the percentage of the invoice total to be charged. Then, a retainer invoice is automatically created and sent to the client. Once the payment for this installment is recorded, another custom function will apply it to the sale invoice, reducing the balance accordingly. This process can be repeated for each milestone until the invoice is fully paid.
But wait, there's more!
In addition to the Custom Button, we are also sharing a Related List script. This script displays information about the installment payments, such as the associated Retainer Invoice number, amounts paid, and the invoice balance both in amount and percentage.
But wait, there's more!
In addition to the Custom Button, we are also sharing a Related List script. This script displays information about the installment payments, such as the associated Retainer Invoice number, amounts paid, and the invoice balance both in amount and percentage.
Prerequisites:
1. Create a Connection named "zbooks" to successfully execute the scheduler. You can watch the GIF attached below to know how to create the connection.
2. Create a Decimal-type custom field called "Installments" for the Invoices. This field will dynamically reflect the percentage of the invoice total that has been billed.
3. Create a new Retainer Invoice template with the document title "Installment Payment". Then, copy the template ID (You can get the ID from the URL of the webpage) and substitute it in line 19 of the custom button script. This ensures that all the retainers sent for collecting installment amounts are correctly labeled.
