Logistics and a lot of T.L.A

TLA? On Valentines Day? Isn't it TLC (Tender Loving Care)? TLC is a TLA...or is that TMI (Too Much Information)? LOL. The world is full of T.L.As (Three Letter Acronyms) and logistics loves using them.

I analyzed my last 6 blogs to find out that I used 19 Three Letter Acronyms! Ready for them? Lets go...COI, CES, COO, EXW, FCA, CPT, CIP, DAT, DAP, DDP, FAS, CIF, UPS, LTL, TMS, WMS, VCI and CFR twice in 2 different ways CFR meaning Cost and Freight (Incoterm) and CFR meaning Code of Federal Regulations.

Some of the above acronyms don't relate exactly to Logistics, CES for example is the acronym for the Consumer Electronics Show. I wrote about CES in my Trade Show blog. Other acronyms are high profile brands in the industry like UPS, which we all know stands for United Parcel Service.

In my new blog we will be adding 2 more 3 letter acronyms. API and EDI. Both of these acronyms are services that are not dependent on logistics but these days logistics is dependent upon them.

For years EDI, Electronic Data Interchange provided communication standards for exchanging electronic data between different companies or organizations. This computer to computer communication eliminated human errors and made order processing between two companies automatic.

Common business documents like purchase orders, invoices and shipping documents could be exchanged from one company to another without human input. EDI standards were established so everyone was on the "same page". Add a new partner? Standards were already in place to transmit and receive the EDI documents.

I helped develop a Transportation Management System (TMS) in the 90s that was used to transmit Shipping related EDI transaction sets to the Big Box stores that required them, back then we utilized a VAN (Value Added Network) to transmit the data, and that data would batch process at a pre determined time. 

Like most standards however, people came up with different standards...for the standards, and then for every standard now we have different versions of those standards. EDI standards ANSI, EDIFACT, TRADACOMS and more have been established, and for communication to work, both companies have to agree to the standard and version they want to work with.

If you are a larger organization you can push your standard back on a smaller supplier, but if your a smaller supplier trying to work with different larger corporations, that each use a different standard, boy are you in trouble. The Web based XML (Extensible Markup Language) standards were developed during this time as well, which began the process for less expensive web based data transfer.

With the advancement of the internet and the use of it as a communication tool, the Application Programming Interface (API) came along.

An API is like an EDI standard, in that it functions as a roadmap to data.  An API is a method of communicating between various software components that specifies routines, data structures, object classes, variables and remote calls. What this means is a new standard of "getting" and "posting" information between companies over the internet rather than over a private VAN.

There are Remote APIs and Web APIs but both allow for interactions between a companies data assets and those making the calls for that data. The differentiation here between EDI and API is that an API allows you to communicate in real time what you need, when you need it, using different standards but returning or posting only the information needed. 

With EDI you would send a transaction set, Set 858 is shipping information, all the shipping data fields would be populated and the file would be sent to the recipients computer, the recipients computer would then generate an EDI confirming receipt, "Acknowledge" The data transfer.

In many cases in the EDI world, a server may process these transactions in batches, so there may be a delay in the response. With API you have a live transaction in that you are connected into or with the recipients data rather than waiting for a batch process to occur to get the info.

We used to dispatch trucks for pickup using EDI and we would have to go and check the status of our EDI upload multiple times to see if the carrier had been dispatched. With an API driven dispatch system an email or notification is immediately sent from the server as soon as the request is made through the API.

Our Accufrate Transportation Management System is an API driven application. We have access to our carriers data from their server. When you get a rate quote through Accufrate its the rate that is coming from that carriers server, in real time. Dispatch of a truck for pickup occurs in real time, you know this because you are posting the data directly to the carriers interface and it is immediately replying.

The great thing about API driven technology is that an APIs design allows you to program into your application a way to access data from another companies application without the users needing to understand the programming inside the other companies modules.

An API provided to us by another company simply says - here is the information I am willing to share with you and this is how you get it, if there is information you want to give me, this is how you give it to me.

The advantage here is that you can give and get only the info wanted and needed at the time of the request, With an EDI the whole file (transaction set) is transferred each and every time.

In explaining this process, I started out by saying I was adding 2 more TLAs to your vocabulary. Did you see what happened? My 2 turned into 4 more TLAs, we added VAN (Value Added Network) and XML (eXtensible Markup Language) as well as EDI and API in just this short description of the use of these communication tools. 

Whether you are in logistics in the B2B or B2C segment I am HTH. TBH you can AMA and if IDK I will find the answer. I GTG but if you ever want to F2F just use my contact info from this page. BTW most of our customers are from WOM and appreciate our exceptional CRM.

If you think sorting through all of these TLAs (Three Letter Acronyms) was next blog is going to be written in all emojis 👴 LOL

Does your delivery need a C.O.I?

In the Transportation Logistics world insurance is required for pretty much everything. General Liability, Motor Truck, Contingent Cargo and Marine Cargo as well as coverage's like Errors and Omissions and Workman's Compensation. You would think by needing all this coverage that moving cargo around the world and into someones business or their home is a pretty risky endeavor. It is! Gateway O.T performs Inside and White Glove delivery services where the building owner or management company requires us to prove we have sufficient insurance coverage while in or on their property. Our Crate and Freight division performs on site packing and crating services for large corporations that require we meet their minimum insurance requirements before we enter their property. Large corporations carry many insurances but have to minimize their risk of claims against those policies by ensuring that the outside contractors they utilize have the coverage needed in case of an accident

You won your Online Auction? Now What?

Gateway Crate and Freight gets a lot of work from people who win online auctions from out of town. Most of these people are out of state and some are even in other countries. We have picked up auction items such as antiques, restaurant equipment, computers, water meter readers, and even a walk through metal detector. Many of our clients do their due diligence BEFORE bidding or purchasing items they may win. Contacting us for a quote on picking up, packing, palletizing, crating and shipping these items gives the prospective buyer a good idea about how much of a "deal" they are actually getting after factoring in packing and transportation. Those that buy first and figure out logistics later find out that the road to great deals online starts with understanding the costs of the entire project, not just the purchase price of the item. Lets look at a recent Gateway Crate and Freight auction purchase project. A Security company in Baltimore, Maryland won an online auc

In this Crisis let me know how horrible I am

This blog has to start the same way most communication starts today with...A Covid-19 Statement: The writer of this blog encourages all readers to have washed hands, and that you have recently sanitized your screen and the keyboard/mouse you are using. It is also best if you are reading this from home since most of America is under "Stay at Home" orders. If you are reading this from work, please go back to doing the 'essential' things you need to do and come back and read this later! If you are sick; I wish you a speedy recovery and hope that you are following the recommendations of your health care professionals. With that out of the way, I would like to talk about Covid-19. As a small business owner of a Transportation-Logistics company, my knowledge of the actual Virus is nothing... ( I should have become a doctor! Sorry mom) so this blog will focus on the impact it has had on small businesses like mine. The U.S Government has recognized the importance of Sma
