A Testimonial to the Quality of our Services

Conor Willers
Operations Manager
I engaged Lumen to undertake some work on a pricing spreadsheet which required computation far beyond my Excel abilities.

Lumen jumped on a call with me and not only listened to exactly what I required but made suggestions on how the sheet could be improved even further.

The finished product was received a couple of days later, and it functioned exactly as I had intended it to. Overall, I was very impressed with the service, quality of the work and suggestions provided.

Hi Lumen Team ,

Thank you both for “dropping everything” to help me solve my problem, Josh, you did it, and blazingly fast too.

Words are insufficient to voice our deep appreciation. We are amazed to receive such professional quality help, so fast and with such a deep sense of empathy and understanding.

Gentlemen, I used to teach four types of exchange:
1. No exchange (rip-off)
2. Poor Exchange (some value but not to the expected standards)
3. Fair Exchange (expected level of service and quality) 4. Exchange in Abundance (Better than expected quality, service, care, etc.)

Most businesses operate on the 3rd type of exchange, however only the 4th type guarantees growth and long term survival. Well done on your superlative service.

The label macro is working perfectly and we’ve almost caught up the backlog.

Many Thanks,
Terry Le Sueur - Director
