What is an escrow or nodal account?
When a platform holds your money in the middle, the law is extremely specific about where it must sit.
It is the difference between a wedding planner who spends the couple's deposit on their own rent and one who keeps it in a separate account and touches it only for the wedding. Both intend to deliver. Only one of them survives a bad quarter honestly.
The platform can see the money and cannot touch it. That fence is the entire regulation.
Whose money is it, in the middle
A marketplace collects payment from a buyer on Monday and pays the seller on Friday. For four days it is holding money that is not its own.
That money must be somewhere. And the entire question of platform regulation reduces to whether that somewhere is properly separated from the platform's own funds.
If it sits in the company's ordinary operating account, then a platform that runs into difficulty has been funding its payroll with sellers' money. This has happened, more than once, in more than one country.
Two accounts that look identical and are not
In Indian usage the terms are related but not identical.
A nodal account is a designated account through which a platform routes collections and settlements, with rules about how quickly money must move through and what may not be done with it. It functions as a pass-through, not a place to accumulate.
An escrow account is broader: funds held by a bank under an agreement, released only when defined conditions are met.
For payment aggregators, RBI rules are explicit: collections must sit in a designated escrow account with a scheduled commercial bank, with a defined set of permitted credits and debits and strict settlement timelines. The money is not the aggregator's to invest, lend, or borrow against.
The line most founders cross by accident
Here is the practical trigger. The moment your platform holds other people's money for any meaningful period, you are conducting a regulated activity, whether or not you intended to.
Many platforms cross that line while thinking of it as a product convenience. The choice at that point is to become licensed and hold funds properly, or to redesign so that a licensed partner holds the money and it never touches you.
Where you meet it
Invisibly, every time you buy from a marketplace and the seller is paid days later. Visibly, in the fine print that says payments are powered by a licensed partner, which is a regulatory boundary drawn in product form.
