# Plans & pricing

helodata offers three pricing models. Pick whichever matches your usage shape; you can mix them within one account.

## 1. Pay-as-you-go

Per-unit price with no commitment. Best for early stage usage, irregular bursts, or testing.

| Product     | Unit           | Price      |
| ----------- | -------------- | ---------- |
| Residential | per GB         | from $4.50 |
| Mobile      | per GB         | from $8.00 |
| ISP         | per IP / month | from $2.50 |

Billed against your prepaid balance. Top up via [Payment methods](/account-and-billing/payment-methods.md) or [Auto top-up](/account-and-billing/auto-topup.md).

## 2. Subscription plan tiers

Commit to a monthly volume, get a lower unit price. Unused volume rolls into the next month up to **50% of the plan cap**; beyond that it's lost.

### Residential

| Tier       | Monthly GB | Price  | Effective $/GB |
| ---------- | ---------- | ------ | -------------- |
| Starter    | 50 GB      | $200   | $4.00          |
| Pro        | 500 GB     | $1,500 | $3.00          |
| Business   | 2,000 GB   | $5,000 | $2.50          |
| Enterprise | Custom     | Custom | from $1.80     |

### Mobile

| Tier       | Monthly GB | Price  | Effective $/GB |
| ---------- | ---------- | ------ | -------------- |
| Starter    | 25 GB      | $200   | $8.00          |
| Pro        | 250 GB     | $1,500 | $6.00          |
| Business   | 1,000 GB   | $5,000 | $5.00          |
| Enterprise | Custom     | Custom | from $4.00     |

### ISP

ISP doesn't have GB tiers — it's per-IP. Annual commits get **10% off** the monthly rate. Volume discounts kick in at 100, 500, and 2,000 IPs.

## 3. Annual commits

For Pro+ tiers and ISP: prepay 12 months, get **10% off**, locked rate for the year. Best when you can predict usage.

Cancel an annual commit mid-term: pro-rated refund at the **monthly** rate (you lose the annual discount on the period already used).

## Picking a plan

Rough guide:

| Monthly residential GB | Recommended                |
| ---------------------- | -------------------------- |
| < 25                   | Pay-as-you-go              |
| 25–250                 | Starter                    |
| 250–1,500              | Pro                        |
| 1,500–8,000            | Business                   |
| > 8,000                | Enterprise (contact sales) |

You can change tier any time:

* **Upgrades** are prorated and take effect immediately
* **Downgrades** take effect at the next renewal

Switching between pay-as-you-go and subscription is just **creating** or **cancelling** a subscription — your sub-users and API keys don't change.

## Plan-level limits

Beyond per-GB price, plans differ on:

## Currencies

Default is USD. We also bill in EUR and GBP for accounts with billing addresses in those regions — set under **Billing → Default currency**.

## How to change plan

**Billing → Plans → {Product}** → pick the new tier → confirm. Mid-cycle upgrades are prorated to the day.

Via API:

```bash
curl -X PATCH -H "Authorization: Bearer API_KEY" \
     -d '{"plan": "business"}' \
     https://api.helodata.com/v1/subscriptions/sbn_01HX...
```

See [Subscriptions API](/api-reference/subscriptions.md).

## Enterprise

For workloads above the Business tier (or with custom terms — invoicing, SOC2 attestations, private IP pools), email **<sales@helodata.com>**. Typical turnaround: pricing within 1 business day, contract within 1 week.
