Payment API for New SaaS and AI-Built Apps

Who this is for

More products now go from idea to a working checkout in weeks rather than months, often built or assisted by AI tools, by a solo founder or a small team. A common blocker is not technical: it is that many established payment providers size their onboarding around businesses that already have months or years of processing volume to show. A product that launched last month does not have that, and should not need to invent it.

This guide is for exactly that case: a new SaaS, app or AI-built product that needs to collect payments from customers in Indonesia, Vietnam, Bangladesh or Pakistan and has little or no prior payment-processing history to present.

What is still required, new business or not

Being new changes what evidence PAYJN asks for, not whether identity and registration checks apply. Every applicant, new or established, is expected to provide:

• A real, identifiable contracting entity or individual, consistent with what the chosen market requires for a merchant of your type.
• A live or demonstrable product, with a public URL or a way to see what the customer actually gets for their payment.
• A clear, accurate description of what is being sold; disclosing any regulated activity, wagering, prizes or cash-redeemable features truthfully.
• A named contact able to handle integration, transaction enquiries and reconciliation.

None of this is waived for a new business. What changes is the next section.

What is relaxed for a new business

For a business with no prior processing history, PAYJN can relax, case by case:

• Historical transaction statements or an existing merchant account with another provider.
• A minimum track record of live revenue before a first review.
• Proof of an existing large customer base.

Instead, eligibility and expected volume are assessed from the business model, the product itself and a forecast, confirmed and revisited as real usage comes in. A good-faith estimate that turns out to be wrong is not by itself treated as misrepresentation; a forecast or any other information given in bad faith, deliberately inflated or otherwise misleading, is reviewed accordingly and can affect or end the relationship.

Build a lighter evidence pack

1. Product: a working demo or public URL, and one sentence on what the customer is actually paying for.
2. Business model: one-time purchase, subscription, usage-based or marketplace, and who is the contracting entity.
3. Target market and methods: which of Indonesia, Vietnam, Bangladesh or Pakistan you need, and the specific methods (for example QRIS and virtual accounts, VietQR and MoMo/ZaloPay, bKash/Nagad/Upay, or JazzCash/Easypaisa) relevant to your customers.
4. Forecast volume: an honest estimate of monthly transaction count and average order size; "we don't know yet, but we expect roughly X" is an acceptable starting answer for a pre-launch product.
5. Technical readiness: whether you can implement a callback endpoint and a basic status-query flow, even if you have not built it yet.

Send this in your first enquiry instead of trying to construct a processing history you do not have.

Hypothetical new-product case

A two-person team ships an AI writing tool over a few weeks and wants to charge customers in Indonesia by QRIS and virtual account from launch day. They have never processed a payment before. This is an invented example, not a specific applicant.

Instead of asking for processing history that does not exist, the review focuses on: is the product real and does it do what the landing page claims; who is the contracting entity; what is the realistic early volume; and can the team implement the callback and status-query flow correctly. A pre-launch forecast, revisited after the first weeks of real usage, is a normal part of this review, not a reason to decline it outright.

Frequently asked questions

Does a brand-new company need transaction history to apply?

Not necessarily. PAYJN can relax the processing-history requirement for a new business, case by case. It still requires a real, identifiable entity, a genuine product and an honest volume forecast.

What if my pre-launch volume forecast turns out to be wrong?

A good-faith estimate that misses is normal and expected for a pre-launch product; it is revisited against real usage, not held against you. Deliberately inflated or misleading numbers are a different matter and are reviewed accordingly.

Can a solo founder or a very small team apply?

Team size by itself is not the eligibility test; the contracting entity, product and disclosed business model are. Confirm your specific structure during review.

How long does a first review take?

This varies by business and is confirmed case by case; PAYJN does not publish a fixed turnaround time. Sending a complete evidence pack in the first enquiry, rather than a partial one that needs follow-up questions, is the main thing a new business can control.

Does this apply outside Indonesia, Vietnam, Bangladesh and Pakistan?

This guide focuses on those four markets. For another market PAYJN covers, ask the team whether the same case-by-case flexibility on processing history applies; it is not assumed by default.

What remains subject to confirmation

This guide describes how a new business's evidence pack is evaluated; it is not a pre-approval or a promise of onboarding for any individual applicant. Methods, limits, fees and settlement terms are confirmed for each approved business, and PAYJN can decline an application at its discretion, new business or not.
