Factor is no longer onboarding new firms. Sonra is practice management for architecture firms - time against phases and fees and resourcing - open to new firms today, with a 30-day free trial and one flat price.
Last updated
Short answer: Factor AE has stopped onboarding new firms, and existing customers don't have to do anything yet. If you use Factor today, you can stay as you are; if you're choosing a tool now, Factor isn't an option, and Sonra is built for the same kind of practice.
In its own FAQ, dated 1 October 2026, Factor says it is "no longer onboarding new firms" and introduces prospects to Monograph instead. Existing customers keep their accounts, data and support, and keep their pricing through their current term and next renewal. Future product development is moving to Monograph.
That leaves existing customers with a decision to make before renewal: move to Monograph, or look at alternatives. Sonra is a smaller, simpler option for small practices. Time goes against projects and phases, every phase has a fee budget, and you can see where each phase will land once the open tasks are done. It was built by a former architect for practices of roughly 5-25 people, at $180 a month flat for the whole firm.

Why small practices pick Sonra when they review their options.
Start a 30-day free trial and bring your hours across while Factor keeps running. Nothing is switched off until you decide, and your renewal date stops being the deadline.
Time by project and phase, a fee budget for every phase, and resourcing. Sonra is built for practices of roughly 5-25 people, and the team can be logging the same week.
$180 a month for the whole firm, however many people use it. No seats to count and no tier to move up as you grow.
Factor is a solid product, and nothing forces you off it today. You're probably better served not switching to Sonra if:
If you want a simpler tool at a flat price, and you'd like to try it with your own hours before your renewal comes round, that's what the 30-day trial is for.
What firms ask when comparing the two.
No. Factor's own FAQ, dated 1 October 2026, says Factor is no longer onboarding new firms and that prospects are introduced to Monograph instead. Existing customers can keep using Factor, with support, and future product development is moving to Monograph.
No. Factor says there is no immediate change required: accounts and data stay in place, support continues, and existing customers keep their pricing through their current term and next renewal. Many firms use that window to look at their options before deciding.
Yes, for architecture practices of roughly 5-25 people. Like Factor, Sonra covers time tracking by project and phase, phase fee budgets and resourcing in one tool. It is available to new firms today, with self-serve sign-up, a 30-day free trial and one flat price of $180 a month for the whole firm.
Yes. Export your project and timesheet data from Factor as CSV and we'll help you map projects, phases, rates and hours into Sonra during your 30-day trial, so each phase budget starts from where the job actually is. Run it alongside Factor until you're happy; there's no need to wait for your renewal date to start.
Monograph is the path Factor points existing customers to, and it is a larger, more configurable platform. Sonra is smaller and simpler, built for small practices that want the team to actually log time and want to see each phase against its fee, at a flat price. See our Monograph comparison for the details.
