How to create simple payment plugin

I would need to create (or recycle) payment plugin for "pick and pay in the shop" type of transactions. I would either want to know how to create simple payment plugin (similar to bank transfer plugin) or recycle an existing one. Any ideas?

I haven't tried this myself yet but I suppose you can change the existing bank transfer plugin if you're not gonna use that and change it to fit your needs.

Basically you would just change the name of the plugin to "Pick up" like you said, or something similar and then in the description put a small explanation like "Choose this option to pick up your order and pay in the store".

Then in the 'Bank account information' field you would put something like "Thank you for your order. Your order will be prepared and you can come to pick it up and pay in the store" and then maybe some address information and store opening hours.

It should work.

Of course, if you also want to use the bank transfer plugin you would have to copy that first. I see there isn't an option for that, maybe Nicolas can help out there.

I am going to use bank transfer plugin so unfortunately it's not an option. And I couldn't find an obvious way to copy plugin. Guess I will need to wait for Nicolas to respond.

For your "pick and pay in the shop" payment method, you can use the collect on delivery plugin.
You will have to change its name and override the texts on the last screen of the checkout via a translation override:

I am using collect on delivery plugin as well.

try duplicate or change some another plugine...

You can use the western union plugin then. It's also an offline plugin like the bank transfer, collect on delivery and check plugins.

Thanks Nicolas, worked ok for me.
