Client Payments: Processing a Previous Balance or a Payment Not Tied to a Session
When migrating from another system or managing practice billing, you may need to collect an outstanding balance, charge a non-session fee, or record an existing client credit. You can handle these scenarios using a standalone product bill, a retroactive appointment, or a credit balance adjustment.
➡️ Setup Step for Migrations: Turn off Auto-Pay for clients with carried-over balances before generating new bills so they can review charges before their card is billed. Re-enable Auto-Pay once the past balance is paid in full. Learn more in our Billing Automation: AutoPay guide

Video Tutorial
Watch this video tutorial to learn how to process previous balances, issue non-session product bills, and record carried-over client credits in Sessions Health.
Method 1: The Product Bill Method
A Product Bill is the fastest way to issue a one-time charge without creating or altering calendar appointments.
Step 1: Open a New Bill
- Open the client's chart.
- Click the Billing tab.
- Click New... > Bill.

Step 2: Set Billing Responsibility
Select Self-Pay. Product bills are not tied to insurance-eligible CPT codes and must be set to Self-Pay.
Step 3: Add Line Items / Products
- Click Add a Product under Line Items (or + Add Product in the top-right corner of the section).
- Choose your product option:
- Pre-Saved Product: Select an existing item from the list at the top of the pop-up window.
- Custom Product: Under Or, add a custom product, enter a Name and Price.
- Click Add.


💡 Optionally Create Default Products: To save time, you can pre-create reusable line items for frequently charged fees. Learn how to set these up in our guide on Client Bills: Products.
Step 4: Set Details & Create
- (Optional) Add notes in the Additional Comments field.
- Choose a timeframe from the Due drop-down menu.
- Click Create Bill.

Step 5: Share or Collect Payment
- Share: Click the three-dot menu (...) in the top-right corner and select Share... to email the bill to the client.
- Collect Payment: Click Add Payment at the bottom of the page to process a card through Stripe or record an external cash, check, or manual payment.

Method 2: Retroactive Appointments
Use this method if you need past session balances tied to official CPT service codes, need to add modifiers, or plan to bill insurance.
💡 Already Imported Past Sessions? If past services were brought over during your data import, skip directly to Step 2.
Step 1: Add the Past Appointment
- Navigate to Calendar and click the past date of service.
- Select the Client and choose the Service Code.
- Adjust the fee or add modifiers if applicable, then click Save.
See Creating and Managing Appointments for more details.
Step 2: Generate the Bill
-
Click the appointment on your calendar to open the flyout menu and select Generate Bill.
(Note: You can also generate bills from Client Billing > Unbilled or from the Billing tab on the client's chart).
- Choose Self-Pay or Insurance and enter any applicable co-pay or co-insurance amounts.
- Click Create Bill.

Step 3: Collect Payment or Submit Claim
- For Client Balances: Click Add Payment on the bill page. See Client Payments: Processing a Client Payment for complete steps.
- For Insurance: Navigate to Insurance > Pending Submission, select the claim, and click Submit Selected Claims. For detailed instructions on submitting claims, see Claims: Individually Submit Claims.
Handling Carried-Over Credits
If a client has an unapplied credit or overpayment carried over from a previous system, you do not need to generate a new bill. Log the credit balance directly onto their chart:
- Open the client's chart.
- Click the Billing tab, then select Settings.
- In the Client Credit field, enter the credit amount.
- Click Save.
Once saved, Sessions Health automatically deducts from this credit balance to cover the client's responsibility on their next generated bill.

Frequently Asked Questions
Which method should I choose for past balances?
Use Method 1 (Product Bill) if you want a simple, one-time bill without cluttering your calendar. Use Method 2 (Retroactive Appointments) if you need full clinical session history, CPT codes, or insurance claim filing.
Can I bill insurance using a Product Bill?
No. Product Bills are restricted to Self-Pay because they do not contain CPT codes or insurance-eligible billing details.
Will creating a past appointment trigger an email to my client?
No. Appointments scheduled for past dates do not trigger automated appointment reminders or calendar invitations.
Can I edit a bill after creating it?
Yes. To update general bill details like the Due Date or Additional Comments, click the top-right three-dot menu (...) on the bill page and select Edit. To modify or remove specific line items, services, or prices, click the three-dot menu (...) located directly inside the Description table on that item's row.
