Overview
When you create an invoice in PhotoBiz, the invoice saves the item details and tax settings that are in place at that time. If you later edit a sales tax line or update an existing eCommerce item, those changes will not automatically update invoices where that item has already been added.
This guide explains how invoices work after products, services, or tax settings are changed. You will also learn how to manually update an existing invoice so the correct pricing, item details, or tax amount appears before sending it to your client.
Invoices keep the original details from the time they were created. This helps prevent unexpected changes to invoices that may have already been reviewed, sent, or paid by a client.
If you update any of the following after creating an invoice, the existing invoice will still show the original information:
Only new invoices created after your updates will automatically use the new item details or tax settings.
Log into your PhotoBiz account and click QUOTES & INVOICES in the left-side menu.
This opens the Quotes & Invoices area, where you can manage existing invoices and create new ones.
At the top of the Quotes & Invoices panel, click INVOICES.
Open the invoice you want to update by clicking on the Invoice Number. Make sure you are editing the correct invoice before making changes, especially if the client has multiple invoices in your account.
Click the Edit button on the upper right side of your invoice to make changes to the existing invoice.
You can update the invoice by adjusting item details directly. This may include changing the price of a product or service, updating the quantity, adding new items, removing old items, or editing the description shown on the invoice.
If you updated a sales tax line after the invoice was created, you will need to update the invoice item so the invoice can recalculate based on the current tax setup.
The rigth side panel will open. Click the Item Name you want to update. Update Item for the invoice item you need to refresh or edit.
After the item is updated, the invoice total will recalculate automatically. Review the subtotal, tax amount, and final balance to make sure the invoice reflects the correct pricing and tax details.
If multiple items need to be updated, repeat this process for each item on the invoice.
Click Update Item for the invoice item(s) you’ve edited. The invoice total will update automatically.
Review the updatd invoice and confirm the amounts are correct. Send the updated invoice to your client so they can see the corrected pricing or tax amounts.
Changes you make to products, services, or tax settings only affect future invoices. For any existing invoices, you’ll need to edit them manually to apply your updates.
Changes made to products, services, prints, digital images, packages, or sales tax settings only apply automatically to new invoices created after those changes are saved.
For existing invoices, you must edit the invoice manually if you want the updated details to appear.
This is especially important if you recently changed:
If an invoice has already been paid, review it carefully before making changes. You may need to create a new invoice, issue a refund, or contact PhotoBiz Support for help depending on the situation.
Why did my invoice still show the old price after I updated the product?
The invoice saved the product price that was active when the item was originally added. Edit the invoice and update the item manually to apply the new price.
Why did my tax rate not change on an existing invoice?
Sales tax settings are saved on the invoice when the item is added. If you update your tax settings later, existing invoices do not update automatically. Open the invoice, edit the item, and update it so the invoice can recalculate.
Will new invoices use my updated prices and taxes?
Yes. New invoices created after your product, service, or tax changes are saved will use the updated information automatically.
Do I need to update every item on the invoice?
Only update the items that need to reflect the new pricing, description, quantity, or tax settings. If multiple items are affected by the change, update each affected item before sending the invoice.
