The longer dimension of the topic is generic gyaan about:
What is UPI?
- How UPI works?
- Who can use UPI?
- What can we do with UPI on WordPress?
WP has plethora of eCommerce avenues: WC (WooCommerce) | EDD (Easy Digital Downloads) | GF (Gravity Forms) | GiveWP | etc.
Most of them have some Indian payment gateway extension/add-on/plugin.
BUT Payment Gateways charge a transaction fee + Need documentation, approvals, integrations and the odds.
Moreover, if do not have a registered Firm/Company, the process gets more complicated.
What if you are Tutor, Coach, Musician and anyone, who would like to collect payment in the most simple manner, without fees/deductions and moreover without the headache of dealing with ‘hazaar’ procedures.
IF simply direct payment is required. UPI is the best solution.
WP – at the core is a publication tool, thus widely adopted.
If collecting payment can be as simple as a STICKY POST, what else do you need 🙂
