Generating a pre-bill

One of the invoice methods available in Synergy is you can invoice prior to work taking place. This is known as pre-billing. When you use pre-billing you can invoice your customer for work that you have not yet completed. Once that invoice has been issued you can then retrospectively add transactions to the invoice to make up the amount that has been invoiced in advance.

By default, all WIP transactions are selected.

Case 1: No transactions have taken place

1. When you click on the stage you want to invoice, you will only have the invoice method option to pre-bill. You will not be able to choose other methods if you don’t have WIP on that stage.
2. Enter how much of the stage fee you want to invoice either as a percentage (Invoiced %) or as a value (Total ex. Tax) . This is the pre-bill balance for future transactions. You will see a pre-bill line when your invoice is finalized in the transactions page.

Case 2: There are WIP transactions

When you already have WIP transactions that you need to invoice you will be presented with three different invoice methods.

1. Pre-bill. If you have WIP transactions, you can still select pre-bill as the invoice method. This will not allow you to select any of the WIP transactions. The invoice will display the amount you have in either the Invoiced % or the amount in the Total ex. Tax fields. You can choose to invoice the WIP transactions later, write it off or attach it to the pre-bill.
2. Mark up/mark downThis is the selected default method when you have WIP. When you use this method, your transactions are marked up or marked down depending on the Total ex Tax field.
3. WIP + Pre-billIn this method your WIP can not be marked up or marked down. It will be used at charge value. If your invoice is greater than your WIP transactions the remaining balance will be the pre-bill.
   Example: You have WIP amounting to $400 but want to invoice $1000. When you create an invoice with this method, it will create a $1000 invoice using the $400 in WIP and $600 as a prebill.
