Managing contractors in every city?
Company-wide rollouts get messy fast when every market has its own vendor.
A different vendor in every market
More calls, more contracts and nobody accountable for the whole project.
Inconsistent installs
Every site wired and documented differently, so support gets harder over time.
Invoices from everywhere
Billing scattered across contractors makes costs hard to track.
Tandem Data brings it all together with one team, one standard and one point of contact.
What we provide, nationwide
Every service your locations need, from one provider

Case study
60 distribution warehouses for a North American distribution company
60warehouses
10K–1Msquare feet per site
3services at every site
Challenge
The company was hiring a different low voltage contractor in each market. Quality varied widely and problems often weren’t found until site turn-up, and every new vendor meant explaining their expectations from scratch.
What we did
Installed the infrastructure cabling, WiFi and telephone systems at all 60 warehouses, from 10,000 to 1 million square feet, as each site came online, with one team handling every market so expectations were set once.
Result
Every site was turned over with a fully tested and documented system, on time and on budget.
We were looking for a single point of contact for our telecom service needs to handle our national footprint and supplement our corporate telecom department. Tandem Data is very responsive in getting our requests handled in a timely manner. I cannot imagine using another group after this experience.

Common questions
Nationwide service FAQ
Which areas do you cover?
We serve all 50 U.S. states and Canada. Our National Accounts Team manages every project from our Dallas headquarters.
Do you use your own technicians or local partners?
Both. Our own technicians handle installs, supported by vetted local partners depending on each market’s workload, for a network of 901 qualified technicians. Every project is coordinated by our National Accounts Team, so you have one point of contact no matter who is on site.
How quickly can you get a technician on site?
Non-emergency service is typically on site within 2–5 days, and emergency service is same day.
Can you support the phone systems we already have?
Yes. We program and support Avaya, NEC and Nortel systems, including remote programming, and can move locations to hosted VoIP when you’re ready.
Can billing for all our locations go through one contact?
Yes. Billing runs through a single point of contact, so you aren’t chasing invoices from contractors in every city.
