# Data Input

</Tip>

Nectar provides three ways to bring utility data into the platform. Each method is designed for a different use case, so you can choose the one that best fits your workflow — or combine all three.

  <Card title="Connections" icon="plug" href="/docs/platform/data-input/connections">
    Automatically sync bills from online utility portals on a recurring schedule.

  <Card title="Uploads" icon="cloud-arrow-up" href="/docs/platform/data-input/uploads">
    Upload PDF, image, or spreadsheet utility bills for AI-powered extraction, then reprocess with
    feedback when needed.

    Enter bill data directly when you don't have a digital document.

## Choosing a method

| Method           | Best for                                                           | Automation level               |
| ---------------- | ------------------------------------------------------------------ | ------------------------------ |
| **Connections**  | Ongoing bill collection from utility portals                       | Fully automated                |
| **Uploads**      | Bulk ingestion of historical bills or one-off documents            | Semi-automated (AI extraction) |
| **Manual entry** | One-off bills, corrections, or data that isn't available digitally | Manual                         |

You can use any combination of these methods across your portfolio. Bills created through any input method appear in the same unified [Data Inventory](/docs/platform/data-inventory/bills).

## FAQ

<AccordionGroup>
  <Accordion title="What file formats can I upload?">
    Nectar accepts **PDF**, **PNG**, **JPG**, **XLSX**, and **XLS** files. Each file should contain a single utility bill for the
    best extraction results.
  </Accordion>

  <Accordion title="How long does it take to process a bill?">
    Most single bills are processed in **under 5 minutes**. For batch timing by upload size, see the
    volume table in [Data Input FAQ](/docs/platform/data-input/faq#how-long-does-upload-processing-take).
  </Accordion>

  <Accordion title="Can I reprocess an upload if extraction looks wrong?">
    Yes. Open the job in [**Data Input > Uploads**](https://dash.nectarclimate.com/data-input/uploads), choose **Reprocess with feedback**
    on the document, and describe what should change. See [Reprocess with feedback](/docs/platform/data-input/upload-detail#reprocess-with-feedback)
    and the [Data Input FAQ](/docs/platform/data-input/faq).
  </Accordion>

  <Accordion title="Can I connect any utility company?">
    Yes. Nectar uses URL-based matching to identify utility providers. If your provider isn't
    already in the catalog, request it — Nectar adds new portal integrations. Email
    [support@nectarclimate.com](mailto:support@nectarclimate.com) with the provider name and portal URL.
