Who We Are

Seine Calculations is a bookkeeping company located in rural Ste. Anne, MB, along Highway 210. Originally founded in 2009 as Aspen Lane Technology by Jeff and Cecile Penner, the company offered both bookkeeping and IT services. Following the sale of the IT department in late 2024, we rebranded as Seine Calculations to focus exclusively on bookkeeping.

We are dedicated to supporting our clients through clear communication and strong customer interaction.
