From the inbox to the bank

Follow one ticket through ITFlow. Every step happens in the same place, so nothing gets typed twice.

  1. 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.

    The tickets list, filtered to open tickets, with status, priority, assignee, SLA and billing for each

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

    A client overview: contacts, location, what needs attention, open tickets and quick notes

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

    A ticket with its conversation, internal notes, time logged, SLA, contact and site

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

    An invoice for managed services with per-user and per-server lines, its payment and history

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

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

Know every client's setup without asking

ITFlow keeps the documentation your technicians reach for, organized the way an MSP works: by client, linked together.

A client's networks: guest wireless, internet circuit, office LAN and server VLAN
Networks with their VLANs, DHCP ranges and the addresses in use
A client's credentials with tags, 2FA, what each is for and when it was changed
Passwords, encrypted, with 2FA codes and when each was last changed
  • Assets with warranties, licenses, network ports and the people who use them
  • Networks, IP addresses, racks and switch port maps
  • A password vault with 2FA codes, rotation reminders and secure share links
  • Domains and certificates, with expiry warnings
  • Documents written from templates, with versions
  • Software, licenses and services, and the vendors behind them

Where it helps

  • Draft a reply from your notes, for the client or as an internal note
  • Triage new tickets: a category, a priority and why
  • Summarize a long ticket and save it as a note
  • Write a ticket up as a knowledge base article
  • Brief you on a client before a call or a review
  • Draft and review documents
  • Reword in a different tone, or translate into 30 languages
  • Write a quote from a sentence, priced from your catalog
The Write it with AI window on a quote, with a scope, catalog lines, labor and a line to price
A quote written from one sentence. Prices come from your catalog and the client's rate, never from the AI.
An AI summary of a ticket: the problem, what has been done, where it stands and next steps
A ticket summed up for whoever picks it up next.
  • Passwords and keys are taken out before anything is sent
  • A role permission decides who can use AI
  • Every request is logged, with its cost in tokens
