Everything an MSP runs on
Documentation, tickets, billing and the books share one database, so each part knows what the others know.
-
Client documentation
Contacts, locations, assets, networks, licenses, domains and documents, organized by client and linked together.
-
Support tickets
Email to ticket, priorities, SLAs with business hours, templates, recurring tickets and a board view.
-
Invoicing
Quotes, invoices and recurring invoices, with reminders, statements and online payment through Stripe.
-
Password management
An encrypted vault for client passwords, with 2FA codes, rotation reminders and secure share links.
-
Client portal
Clients open and follow their tickets, see invoices and quotes, pay online and look up their devices.
-
Accounting
Income, expenses, bank accounts and reconciliation, budgets, and profit and loss.
-
Calendar
Scheduled tickets, maintenance windows and renewals, with feeds for Google, Outlook and Nextcloud.
-
Bulk email
Maintenance notices, outage updates and announcements to your clients' contacts.
-
Leads
Track prospects as leads, and turn them into clients when they sign.
-
REST API
Connect your RMM, CRM and scripts, with API keys that can be limited to one client.
-
AI, if you want it
Draft replies and sum up tickets with the provider you choose, or a model on your own hardware. Off until you turn it on.
-
Modular
Turn off what you don't use. Roles, two-factor sign-in and an audit log look after the rest.
ITFlow in action
Follow one ticket from the inbox to the bank. Every step happens in the same place, so nothing gets typed twice.
-
Mail to your support address turns into tickets, matched to the client and the contact who sent it. Work them as a list or a board, with SLA timers, priorities and who has what.

-
Contacts, sites, assets, networks, passwords, licenses and documents sit under the client, with what needs attention at the top.

-
Reply to the client or leave internal notes, log time as you go, and keep the asset, contact and site beside the conversation.

-
Time, expenses and hardware go onto invoices at the client's rate. Recurring invoices count users and devices for you each month.

-
Clients see their tickets, invoices and devices in the portal, pay by card, and can save a card for autopay.

-
Income, expenses and profit by month, what each client is worth, what is owed and what is still unbilled.
