Billing & Invoice Guide

Last updated: September 1, 2026

Everything you need to know about managing your ApiSorcery paid subscription — payment methods, invoices, upgrades, and cancellations.

For payment troubleshooting (declined cards, 3DS, VAT questions), see the Payment FAQ.

1. Where Billing Happens

All billing for apisorcery.com is handled by Paddle.com Market Limited, our merchant of record. You interact with Paddle in two places:

• Checkout — the secure overlay that appears when you click "Upgrade"
• Customer portal — a self-service page for updating payment methods, downloading invoices, and canceling subscriptions

Open the customer portal from Console → Account → Manage subscription, or from the link in any Paddle billing email.

2. Payment Methods

Paddle supports:

• Visa, Mastercard, American Express, Discover, JCB
• Apple Pay and Google Pay (browser dependent)
• PayPal (in supported regions)
• SEPA Direct Debit (EU)
• ACH direct debit (US, for annual plans)
• Wire transfer (annual plans over a minimum threshold — contact support)

Locally issued cards from mainland China may not clear 3DS verification via Paddle. If you are in mainland China, we recommend using apisorcery.cn with WeChat Pay.

3. Change Payment Method

1. Open the customer portal (Console → Account → Manage subscription)
2. Click Payment method
3. Add or select a card, then save

The new method is used from your next renewal onward.

4. Download an Invoice

Every successful payment triggers an emailed invoice from Paddle (sender: paddle@paddle.com). You can also:

1. Open the customer portal
2. Click Payments or Invoices
3. Choose the invoice and Download PDF

Invoices include your billing details, the payable amount, and any VAT / GST / sales tax collected.

5. Add a VAT ID / Tax ID to Invoices

If you need your VAT ID (EU / UK), GST number (AU, NZ, IN, SG), or other tax ID printed on future invoices:

1. Open the customer portal
2. Go to Billing details
3. Enter the tax ID and save — it appears on invoices issued after the change

To restate an already-issued invoice, email support@apisorcery.com with the invoice number and the tax ID you need added. Paddle can re-issue in limited cases.

6. Change Plan or Billing Frequency

1. In the console, go to Account → Subscription
2. Click Change plan and pick the new plan (Pro ↔ Team, monthly ↔ annual)
3. Confirm — Paddle handles proration automatically

Upgrades apply immediately with a pro-rated charge for the remainder of the current period. Downgrades apply at the end of the current period. See Subscription Terms § 5 for detail.

7. Cancel a Subscription

1. Open the customer portal (Console → Account → Manage subscription)
2. Click Cancel subscription
3. Confirm

Cancellation stops future auto-renewals. Paid access continues until the end of the current billing period. Cancellation does not automatically issue a refund — see the Refund Policy if you want a refund as well.

8. Pause a Subscription

If Paddle exposes the Pause option in your portal, you can suspend billing and access for a limited period, then resume later. If the option is not visible for your plan, contact support.

9. Failed Renewal

If a renewal charge fails, Paddle automatically retries over several days and emails you to update your payment method. Your service is not suspended immediately. Update your card in the customer portal to resume the retry cycle.

10. Refunds

See the Refund Policy. In short: 14-day no-questions-asked window for first-time purchases, and case-by-case beyond that.

11. Business / Team Purchase Order

For teams that require a purchase order or wire transfer for an annual Team plan, email support@apisorcery.com with the requested plan, seat count, and billing entity — we will coordinate with Paddle to issue a proforma invoice.
