Method CRM and fastbill, answered
What can start an automation from Method CRM?
Any of Method CRM's 6 triggers in the catalog, including New Activity, New Contact, New Customer or Customer Lead (QuickBooks Only) and New Customer/Vendor or Customer/Vendor Lead (Xero Only). Describe the moment in plain language and your agent picks the right one.
What can your agent do in fastbill when something happens in Method CRM?
Any of fastbill's 18 actions, including Create Customer, Create Invoice, Create Offer and Create Revenue. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from fastbill to Method CRM?
fastbill has no triggers in the catalog today, so automations start in Method CRM. If you need the other direction, ask: your agent reads fastbill's API documentation and adds it.
Do I have to build a connector for Method CRM or fastbill?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Method CRM and fastbill without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
