Pivoted my business due to COVID-19 and now I am offering B2B courier services in NY, I started to get some traction and clients and now I am doing everything manually but I need to automate with an integration.
I am trying not to spend resources on programming from scratch before I completely validate the product-market fit.
There are several off-the-shelf logistic programs that will make this efficient for you. Bike messenger services, other couriers, regular carrier services, taxi dispatch, they all have routing and tracking for clients to create the most efficient routes. You have no need at all to create software from scratch. The point for you will be what value can you bring that makes you different from every other one of the dozens of courier services in your city.
What kind of integration you are looking for. There are tools like Zapier that you can use to automate basic stuff.
You can make apps downloading applications.
