# ISV guides

Add e-invoicing to your software and manage customer companies through Partner Platform.

An independent software vendor (ISV) uses its workspace to connect customer companies, map invoice data and submit documents from its own application. Each company can have several branches, with a source identifying the sending system for each branch.

## Send your first invoice

Follow [your first UAE invoice](https://docs.complyance.io/partner-platform/isv/first-uae-invoice/connect/) to create a sandbox key, onboard a company, prepare an invoice, submit it, check its final result and go live in production. Connect onboards UAE companies; for other countries, the first chapter says what to do.

## Manage customers

- [UAE prerequisites](https://docs.complyance.io/partner-platform/isv/companies/prerequisites/): Check onboarding requirements
- [Onboard a company](https://docs.complyance.io/partner-platform/isv/companies/onboard/): Create one company
- [Bulk onboarding](https://docs.complyance.io/partner-platform/isv/companies/bulk-onboarding/): Create several companies
- [Find a company](https://docs.complyance.io/partner-platform/isv/companies/list/): Recover an existing company
- [Add branches](https://docs.complyance.io/partner-platform/isv/companies/branches/): Add another location
- [Customer access](https://docs.complyance.io/partner-platform/isv/customer-access/): Invite customer users

## Operate the integration

Use [mappings and payloads](https://docs.complyance.io/partner-platform/isv/mappings-and-payloads/) to connect new sources, [document counts](https://docs.complyance.io/partner-platform/isv/invoice-counts/) for usage reporting, and [purchase webhooks](https://docs.complyance.io/one-platform/developer-portal/webhooks/purchase-invoices/) to receive events when purchases are stored.

The [portal guide](https://docs.complyance.io/partner-platform/isv/using-the-portal/) explains where these tools live. Use [troubleshooting](https://docs.complyance.io/partner-platform/isv/troubleshooting/) when a request or document does not reach the expected result.
