WorldFirst Card Review: Multi-Currency Virtual Card for Singapore Businesses
Learn how the WorldFirst Card helps Singapore businesses manage global payments, and simplify online spending.
ChatGPT, developed by OpenAI, is the world's most popular AI tool, with hundreds of millions of weekly active users. To meet the needs of its vast and diverse user base, OpenAI offers various pricing plans.
In this article, we'll look at the costs of these plans for businesses in Singapore, along with the features they include—so you can choose the one that best fits your needs and budget.
We'll also highlight the advantages of using a Wise Business multi-currency card to pay for your ChatGPT subscription, including lower fees and better exchange rates.

ChatGPT's paid plans are priced on a per-user, per-month basis.
**However, billing options vary by plan: the Plus and Pro plans are available with monthly billing only; the Business plan offers both monthly and annual billing; and the Enterprise plan is available by contacting OpenAI’s sales team.¹
There are no add-ons to purchase or usage fees to pay after you've subscribed. However, usage limits apply to the different AI models available and vary depending on the plan. For ChatGPT Business, OpenAI also offers standard ChatGPT seats and usage-based Codex seats.
| Free | Plus | Go | Pro | Business | Enterprise | |
|---|---|---|---|---|---|---|
| Monthly billing | USD 0 | USD 20 | Monthly billing only; price shown on OpenAI’s pricing page/local checkout | From USD 100 per month | USD 25 per user/month Min 2 standard ChatGPT seats | Contact sales |
| Annual billing | USD 0 | Not available | Not available - Go is billed monthly | Not available | USD 20 per user/month, billed annually Min 2 standard ChatGPT seats | Contact sales |
**ChatGPT is no longer priced and billed only in USD for all users worldwide. OpenAI now supports multi-currency billing for ChatGPT subscriptions purchased on the web, and SGD is listed as a supported currency for Singapore.²
**
You can purchase ChatGPT Plus, Pro, or Business using any major credit or debit card, such as Visa, Mastercard, or Amex. For ChatGPT Enterprise, alternative payment options like invoicing are available.
However, do note that some banks or credit cards may charge a foreign exchange fee and apply a marked-up exchange rate when converting a foreign-currency ChatGPT payment to SGD.
You might also encounter a couple of other scenarios where your business in Singapore gets charged ChatGPT fees in a foreign currency rather than SGD. By understanding these scenarios, you can take proactive steps to manage your billing effectively and avoid unnecessary foreign transaction fees.
| 💡Considerations for Cross-Currency Billing: |
|---|
| Centralised Payment Systems: If your business (eg. a Singapore subsidiary) uses a centralised payment system or corporate credit card based in another country, your ChatGPT account might be linked to this system, resulting in billing in the currency of the payment system rather than SGD. This can lead to additional currency conversion fees. |
| Initial Account Setup: If your ChatGPT account was initially set up by your business in another country before establishing a branch in Singapore, the account might still be billed in the original currency unless updated. OpenAI says existing subscribers may need to cancel and resubscribe after the current billing period ends to switch to a newly supported currency. API pricing is separate and remains listed separately from ChatGPT subscription billing. |
Using a multi-currency account like Wise Business could allow you to lower costs by enjoying minimal conversion rates at mid-market exchange rates.

ChatGPT Free costs USD 0 per month. To use it, you need to sign up with an email address or your Google, Microsoft, or Apple account, but no payment information is required.
The Free plan lets you explore how AI can make everyday tasks easier with these features:
*Limited access to ChatGPT’s current core model
ChatGPT Free is a great budget-friendly option, especially since it lets you explore ChatGPT at no cost. However, the Free plan no longer centres on GPT-4o mini. OpenAI’s current plan pages describe the Free plan as offering limited access to GPT-5 features, messages, uploads, image generation, deep research, memory, context and Codex.
The free plan can still help with tasks like drafting emails and summarising information. However, if you consistently need higher usage limits, faster image generation, more file uploads, advanced reasoning or business workspace features, consider upgrading to a paid plan.
ChatGPT Plus costs USD 20 per month. Singapore users may see the final charge in SGD if localised billing applies, and GST or other applicable taxes may also apply depending on billing details.
Subscribing to the Plus plan helps you boost productivity with expanded access, increased usage limits, and the following features:
*Up-to-date as of time of writing (25 April 2026)
ChatGPT Plus is a solid choice for solo entrepreneurs or small businesses that only need a few accounts. It provides more access to ChatGPT’s current advanced models and tools, including GPT-5 features, rather than GPT-4o.
All in all, it unlocks a powerful suite of tools for writing, coding assistance, research, image generation, and more—while still remaining a fairly budget-friendly option.
ChatGPT Go is OpenAI’s lower-cost paid plan between Free and Plus. It is billed monthly only, with pricing shown on OpenAI’s pricing page or at local checkout where available.
ChatGPT Go gives users more access than the Free plan, including:
ChatGPT Go may suit freelancers, solo entrepreneurs or very small businesses that want higher limits than Free, but do not need the broader access and advanced features included with Plus. If your business needs more advanced reasoning, deeper research, higher file limits or more consistent access to the latest tools, Plus or Business may be a better fit.
ChatGPT Pro costs from USD 100 per month. OpenAI’s current Pro plan offers 5x or 20x more usage than Plus, depending on the Pro tier selected.
Upgrading to Pro gives you the best of ChatGPT, with maximum access and the following features:
*Up-to-date as of time of writing (25 April 2026)
If you want the very best of ChatGPT—with higher usage than Plus, Pro reasoning, maximum deep research, agent mode, Codex and higher limits for intensive creative or analytical work—and you don't mind paying a premium for it, ChatGPT Pro could be the right choice for you. However, if you're on more of a budget and can't justify the higher monthly price tag, one of the lower-cost plans would be a better option.
ChatGPT Business costs USD 20 per user per month when billed annually, or USD 25 per user per month when billed monthly. A minimum of 2 standard ChatGPT seats is required. OpenAI says Business pricing was reduced by USD 5 per month from 2 April 2026.
The Business plan drives team productivity and collaboration by offering everything in the Plus plan, along with:
*Up-to-date as of time of writing (25 April 2026)
ChatGPT Business is likely the right choice if your business has two or more team members who would benefit from a secure shared workspace, admin controls, unified billing, connected business apps and business data protections.
OpenAI does not publicly list fixed prices for the ChatGPT Enterprise plan. Pricing is likely customised based on each organisation's specific needs. For an accurate quote tailored to your organisation's requirements, it's best to contact OpenAI's sales team directly through their ChatGPT Enterprise page³.
The Enterprise plan makes ChatGPT an enterprise-grade tool, with all the security, admin, and collaboration features large organisations expect:
*Up-to-date as of time of writing (25 April 2026)
ChatGPT Enterprise is designed for large organisations that require robust security, data privacy, compliance, customisation, and dedicated support. If your organisation has a team of over 50 people, it's worth contacting the ChatGPT sales team to learn more. If your team is smaller, the Business plan may be a more suitable option.
For Singapore businesses looking to save on their monthly or annual ChatGPT bills, here are a few tips to consider:

Claude is one of ChatGPT’s closest competitors, offering a similarly powerful AI chatbot. While Claude doesn't have as large a user base, it remains very popular.
Both platforms offer free plans, along with enterprise options that require contacting sales for custom pricing. Here’s how their paid plans compare:
These prices exclude applicable taxes. OpenAI now supports SGD as a local billing currency for ChatGPT subscriptions purchased on the web, while API pricing is handled separately.
Which ChatGPT model is best depends on your specific needs for any given task. Here are some of the top ChatGPT models:
Keep in mind that ChatGPT frequently releases new models and updates existing ones, so the names of the best models may change over time. OpenAI says GPT-4o and several older models were retired from ChatGPT in 2026, so references to GPT-4o, o1 and o3-mini should be updated or removed.
OpenAI does offer an API. However, your ChatGPT subscription does not include API access⁵. ChatGPT and the API platform are two separate products and are billed independently. OpenAI’s multi-currency billing article notes that API pricing is separate from ChatGPT subscription billing.
ChatGPT remains the most popular AI tool, but competition is quickly heating up. To get the most out of ChatGPT, a paid plan is recommended—it increases usage limits and grants access to the most advanced models and features. However, the Free plan is still suitable for users with basic needs, such as writing emails, short blog posts, or summarising text.
| 💡 For businesses and individuals in Singapore, ChatGPT no longer bills exclusively in USD for standard paid plans, as OpenAI now lists SGD as a supported currency for Singapore. However, if your subscription is still billed in USD or another foreign currency, choosing a cost-effective payment method can help you avoid unnecessary transaction fees and unfavourable exchange rates. Consider using the Wise Business multi-currency account to manage your SaaS subscriptions from one place. Wise uses the mid-market exchange rate with transparent conversion fees, helping you pay globally without hidden exchange rate markups. |
