Got questions?
Three questions we hear most often.
Do you integrate with the system we already use?
Yes. We've built integrations with Salesforce, POS systems, calendars, and payment gateways. If your current system has an API, we can usually keep it in place and add the missing functionality instead of migrating everything at once.
How much does it cost?
The price depends on scope, so we don't publish a one-size-fits-all price list. After a call and an audit, you'll get a concrete quote broken down by stage, plus a plan of action — usually within a few days. The audit itself comes with no obligations.
How long does implementation take?
We complete the audit within 48 hours, and the first working version usually takes six to eight weeks. We only give a firm timeline after the audit — before that, it would just be a promise with nothing behind it.
