How can I link an invoice to a work order?
Besides being able to
create invoices for a work order, you can also link an invoice to a work order. If you have already created invoices directly in Zoho Books or Zoho Invoice and now wish to associate them with a work order in Zoho FSM, you can easily do so using the
Link Invoice feature.
To link an invoice to a work order:
- Select the Work Orders module from the Work Order Management menu and click the work order to which you want to link the invoice.
- Select the Invoices tab and click Link Invoice.

- In the Link Invoice with Work Order popup, either select an Invoice Number or enter the Invoice ID and click Link.

You can obtain the Invoice ID using the List Invoices API of Zoho Books/Invoice.
Note:
- The linked invoice will be listed under the Invoices tab with the same status as in Zoho Books/Invoice.
- All the service line items in the work order with the billing status Not yet Invoiced will be linked to this invoice. The status of these service line items will change to Invoiced.
- The Billing Status of the work order will change according to the statuses of the invoices in the work order.
- If you attempt to link an invoice to a work order where all the service line items have the billing status as Invoiced, then you will encounter the error message "Work Order has already been invoiced".
Make a Payment
You can record the details of the payment made for an invoice.
- Select the Invoices module from the Work Order Management menu and click the invoice you want to record the payment for.
- Click Record Payment.

- Click Record Payment.
Any custom field added to the Payments Received form in Zoho Books/Invoice will also be listed under the Custom Fields section.

The status of the invoice changes to Paid. The reference number entered here will be updated in the corresponding invoice record in Books/Invoice.

Using Invoice Credits
Any excess amount paid by the customer (i.e. the amount that is not used to record payment for the invoices) will be available as invoice credits in Zoho FSM. These can be used later while recording invoice payment.
In Zoho Books/Invoice, record the excess payment made by the customer. To do so:
- Navigate to Sales > Payments Received and click New.
- In the Customer Name field, select the customer for whom you want to record the excess payment and in the Amount Received field, enter the amount. Click Save.
If there unpaid invoices present for this customer, a popover (Would you like this amount to be reflected in the Payment field?) will be shown. Click No for this amount to be considered as an excess payment.

- Click Continue to Save.

This excess payment will be available as credits when you try to record payment for an invoice for this customer. To use the credits in Zoho FSM:
- Select the Invoices module from the Work Order Management menu and click the invoice you want to record the payment for.
- Click Apply Now in the Available Credits section displayed on top.

- Enter the amount you want to use from the credits and click Apply Credits.

You can either use the credits to record the payment of the full invoice amount or a part of the invoice amount. After you use the credits to record the payment of only a part of the invoice amount, you can proceed to
record the payment of the remaining amount.
