Support
Nexa Systems is a software company in Toronto, Ontario. We build custom Odoo ERP systems and business apps for Canadian companies whose work doesn't fit off-the-shelf software. We host what we build on our own servers in Ontario, and the developers who wrote your system are the ones who support it.
Your ERP runs on Odoo, with our modules added for the rules Odoo leaves out, like ADP funding splits and Canadian payroll. You're never stuck on a one-off system.
We run your system on servers we own in Ontario, so your data stays in Canada. Backups, monitoring, and security updates are on us.
Support runs during business hours, and you talk to the people who built your system. Hosted clients also get an emergency line.
Our mission is to give Canadian businesses software that fits the way they work, and to look after it long after launch.
Every project is different, so there's no price list. We learn how your business runs first, then scope and quote the work that fits it.
