# Billing

Review subscriptions, manage payments, and view invoices and credit history.

Source: https://docs.staging.solesca.com/admin/billing/

Owners and Admins open **Settings › Administration › Billing** to manage the organization's billing.

## Seats and add-ons

**Seats and add-ons** shows paid Design and Engineering seats, terrain licenses, SOL credits, and vouchers. Assign seats and terrain licenses on [Members](https://docs.staging.solesca.com/admin/members/).

Engineering vouchers provide engineering access for individual designs. IX package vouchers provide plan-set access for individual designs. The confirmation dialog explains what is used before you proceed.

## Subscriptions

**Subscriptions** shows your monthly or annual subscriptions, renewal dates, and projected subtotals. Review both current access and upcoming changes when planning a renewal.

**Change your plan** opens [Concierge](https://docs.staging.solesca.com/start/concierge/). Use it to request more seats, add-ons, a plan change, or cancellation.

## Payment methods

Use the payment method section to add or change the card or US bank account used for payments. Saved methods show identifying details, with controls to make a method the default or remove it.

Follow any bank verification instructions shown during setup. A saved default method is used for automatic payments when your billing arrangement includes them.

## Invoices

The **Invoices** table shows invoice amounts and payment status. Use the download action for a PDF or **Pay** for an unpaid balance.

An emailed invoice link also opens a payment page. Review the invoice, choose whether to save the payment method for future payments, and follow the payment prompts.

If a payment link has expired, open a new link from the invoice table or ask an Owner or Admin for help. A bank payment can remain pending while it clears.

## Payment issues

Follow the billing banner or invoice instructions if a payment fails, needs verification, or is overdue. Update the payment method or pay the outstanding invoice as directed.

If organization access is paused, designs remain available to view. Contact Solesca if you have paid and access has not been restored.

## Credit history

**Credit history** lists credit and voucher activity. See [SOL credits](https://docs.staging.solesca.com/admin/sol-credits/) for purchases and usage.
