Billing & credits
Strella supports pre-purchased wallet credits, pay-as-you-go card checkout, and invoiced billing for enterprise. View your balance and transaction history in Billing.
Strella has three ways to pay: pre-purchased credits (a wallet), pay-as-you-go by card at checkout, or an invoice (enterprise). Card payments go through a one-time checkout each time, and Strella doesn't store a card on file.
How they work
| Method | How it works | Who has it |
|---|---|---|
| Wallet | Pre-purchased credits. Strella deducts them when you place a panel order or pay out self-recruited participants. | Available to every organization. |
| Card | Pay by card at a one-time checkout when you place an order. No prefunding, no card stored on file. | Available to every organization. |
| Invoice | Choose invoice at checkout, and Strella bills that order on an invoice instead of charging you up front. | Enterprise customers. Contact sales to enable. |
If your wallet has a balance, Strella draws from it first, and a card checkout covers anything the wallet can't. A wallet only holds funds after you purchase credits, so new organizations start at $0.
Steps
- Open the home sidebar → Billing
The billing page shows your current wallet balance and transaction history.
- Buy credits
Enter an amount and click Purchase to add credits to your wallet. Strella sends you to a one-time card checkout, where it adds a small processing fee. Strella adds the credit to your wallet as soon as the payment clears.
Wallet credits don't expire (until you close the organization).
- Read transaction history
The history table shows every charge and credit: date, amount, category (wallet spend, card payment, incentive, refund, etc.), and the reference order ID for panel orders. Each row carries its own details, so you don't need to click in.
Participants shows how many participants that charge paid for, so you can see what an order bought next to what it cost. The column counts the participants you bought, not the participants who finished. An extension row shows only the participants it added, and a refund row shows only the unused participants returned, so the rows of one order may not sum to its total. Charges that don't buy participants, like a credit top-up, leave it blank.
An order paid by invoice appears as soon as you place it, before you pay the invoice.
- Resync if something looks missing
If a charge you expect isn't listed, open the ⋮ menu above the table and choose Resync all transaction history. Strella rebuilds the list from your payment records and shows a progress bar until it finishes, which can take a few minutes.
Anyone in the organization can resync. The option is unavailable while a resync is already running.
Strella applies charges when you place a panel order or pay out self-recruited participants. It draws them from your wallet, runs them through a one-time card checkout, or bills them on an invoice.
Things to know
- Participant incentives are billed in addition to interview credits. A panel order's total includes both.
- Refunds appear as separate rows. Strella does not reverse the original charge. It adds a refund row, shown in green with a + because the money comes back to you.
- Balance refreshes on page load. If you've topped up in another tab, refresh to see the new balance.
- Invoiced billing isn't customer-self-serve. Contact your account team to set it up.
