Multi Location Pickups - with stand alone app for the store

[Libon]

Hi guys and gals,

I'm looking for an app that can help me solve a problem.
We have an online store with a warehouse that ships orders placed on the website. 
However, we have a number of stores dotted all around where we want to offer local pickup. None of these stores have access to the website admin and have no need for a POS.
Can anyone recommend a app that has a stand alone android app where customers can select local pickup when on the website, pick the store and then the order goes through to the relevant stores app? 
It is a tad more complex, as the order might be fulfilled by the warehouse and sent to the local store ready for collection. but this is a hurdle to cross when the first part is done.

Fingers crossed someone can answer this?

That's correct.

Ideally they would have an app on a phone or tablet that advises them of orders for there location that will be being collected.

Kind regards
