Here are some problems on accuracy to start:
- The digital retailing tool does not use the same calculations the dealer does, so (mostly lease) payments don't match
- Dealers have different policies for how down payment money is applied to the lease cap and many developers don't know how to work with that
- Taxes can vary significantly from one zip code to the next in some states - hell, tax rates can vary within the same zip code! A lot of dealers can't even explain how it works. Techies need expert desking people on staff with an aptitude for algebraic equations.
- Some states have different ways trade equity is handled
- Some states tax differently depending on the purchase price, contract price, or monthly payment amount
- Many states tax differently depending on how the car is paid for
- Incentives from OEMs can vary on SO MANY different terms and variables it will make you sick (I'm looking at you GM)
- Inventory feeds are not always accurate
- What equipment is actually on a new car determines what incentives apply and we know how often that is 100% correct
- What equipment is actually on a used car impacts the book value needed to figure out what the advance is
- Which book value to use can vary by lender
- Not all lenders publish rates to remain competitive - in those cases, payments cannot be displayed for those lenders without a full credit app
Some other technical things people don't think about on the surface
- Storing PII data (even if for a nanosecond) requires SERIOUS security
- Keeping a web service fast for all devices at speeds down to 4G is incredibly limiting (have you seen how slow your dealership website is these days?)
- Can you tell people that Microsoft doesn't even support Internet Explorer anymore?
- Fusing good technology into someone else's bad technology is on par with having unprotected sex in warlord-controlled parts of Africa
And lastly, there are the operational parts of car buying that take 4 hours in the store -
this is the part that truly makes digital retailing fail. And here is the golden statement: If the CRM or DMS is used as the desking, paperwork, and/or contracting piece it is the center of the dealer's operational process. If the digital retailing solution is not working directly with at least the CRM it is a process burden on the dealership staff. So many issues come into focus once this is realized.
