There are 2 ways to charge a client for a damaged item:
*When it comes to charging for damages, one of the best ways to protect against disputes is to ensure you have the client's signature on a project with your damage terms clearly listed.*
1) Add the damage costs to the contract for the client to pay:
Begin by editing the existing contract and create a new line item group called "Fees & Services", for example, and put a "Damaged Item" Service Line Item or custom line item. Then, re-mark it as signed and click Send to client to send them an updated contract/invoice showing the amount due. They'd see the same online payment screen they've already seen and it's obvious what's owed and how to submit payment.
You can quickly add a description and drag and drop any photos into this custom item with proof of the damages.
2) Making the charge on behalf of the client:
Edit the existing contract to add the line item (as in option 1), mark as signed
Next go to the Billing tab and click Capture Payment. You will see a drop down showing you any previously charged cards on that project and you can process the charge yourself.
Caution: charging cards without explicit authorization or at least contractual language giving you the right to do so may make you vulnerable to a chargeback (Stripe charges a $15 fee for per occurrence).
