Quote requests priced. Replied in the Gmail thread.

Centrus integrates with Gmail for UK field service businesses. Quote requests priced from your rate card. Supplier invoices and follow-ups handled inside Gmail.

start with these

Quote requests sit in Gmail until the one person who knows the prices gets to them.

Ask which quote requests are still waiting and get the threads behind the answer. Centrus prices a request from your rate card and replies in the thread from your address. Agents follow up open quotes, match supplier invoices and file mail under the labels you already use.

setup

Every inbox signs in on its own

The rate card and your voice go in once, for everyone, and Centrus only sees the inbox of whoever signed in.

01

Connect Gmail

Each person clicks Connect on the Gmail card in Integrations and signs in with Google. Google Calendar has a card of its own. If your Google Workspace blocks new apps, your Workspace administrator allows Centrus once.

How to connect

02

Give it your voice

Set the tone in Organisation Context. Add the rate card, the email policy and a document of good replies to Train, as uploads or synced from a Google Drive folder.

Organisation Context

03

Hand over the routine

Start by asking in chat. When an inbox job repeats, describe it in Agent Builder, connect the Gmail account it should watch and pick the label. A team account such as accounts@ works too.

What Centrus can read and change in Gmail

Each row is part of your Gmail. Ask works in chat on the web, WhatsApp and Teams. Change notes where only agents can do it. Trigger means an agent starts when a matching email lands under the label.

Gmail questions

It connects Centrus to your Gmail inbox with a Google sign-in. Your team asks which quote requests are still waiting or what a client said last month, and gets the emails behind the answer. Centrus replies in the thread from your address, and agents take the routine: supplier invoices, quote follow-ups and filing under labels.

Yes. Add the rate card to Train, by upload or synced from Google Drive, along with a document of replies you like. Centrus reads the request, finds the price, and writes the reply the way your examples do. Ask for a draft first if you want to check the figure before it goes.

No. Gmail stays your inbox and the record of what was said. Replies go out in the same thread from your own address, drafts sit in Drafts, and agents file mail under the labels your team already uses.

That AI only sees what lives inside Gmail. It does not see your job system, your client portals, your documents or anything else running the business day to day. Centrus sits across everything you use, so it is not limited by what one vendor decided to build.

No. Google Calendar is a separate card with its own Google sign-in. Connect both and one chat can read a request, check who is free and book the visit. Agent Builder does not have calendar steps yet, so bookings happen in chat.

In agents, yes. An agent downloads the PDF or spreadsheet and reads it, which is how supplier invoices become draft bills in Xero. In chat, Centrus reads the email itself and tells you a file is attached, so the file reading belongs in an agent.

Yes. Pick a label, such as Invoices, and filter by sender, subject, body or attachments. Each matching email starts one run. Filters are checked first, so mail that does not match uses no credits, and the trigger does not mark the email as read.

Yes. Agents connect a Gmail account of their own, separate from each person's inbox in chat. Sign in with the team account once and agents can watch its labels and send from it, with an Approval step before anything goes out.

No. Your data is not used to train AI models, and training is switched off on our AI provider account. Data is encrypted in transit and at rest, and access is set per person through tags and roles. Your inbox is read when someone asks or an agent runs, through the Google account you connected.

Gmail comes with every plan, from £299.99 a month. Chat uses message credits and agents use automation credits. Emails the trigger filters skip use none. Plans run month to month, with no lock-in, and paying annually saves 20%.See full pricing
