Last month's margin pack. Already in Excel.

Centrus integrates with Excel for UK field service businesses. The workbooks your office builds by hand, written from live jobs and sent on a schedule.

start with these

The month-end pack is rebuilt by hand from the same exports every month.

Describe the report once and an agent writes it from your job system and accounts, in the format you already send: margin by contract, overnight jobs, who is free and qualified. Ask about a tracker you already keep and the answer comes back with the row numbers.

setup

From a question to a monthly pack

Each person connects their own Excel. Agents connect separately, so a scheduled report never depends on one person staying signed in.

01

Connect Excel

Each person clicks Connect on the Microsoft Excel card and signs in with Microsoft. Chat then works on the workbooks in that person's OneDrive. If your Microsoft 365 asks for approval, IT approves Centrus once.

How to connect

02

Ask a workbook first

Ask about a workbook you already use, then ask for a new one from last month's jobs. Check the first few in OneDrive so the columns match the pack you send today.

What you can ask

03

Schedule the report

When the same report goes out every month, describe it in Agent Builder. Connect Excel on the agent, plus the job system and Outlook, and add an approval before anything reaches a client.

Steps an agent can use

what it covers

What Centrus can read and change in Excel

Chat has 11 Excel tools and the Agent Builder Excel step has 14 actions. Ask works in chat on the web, WhatsApp and Teams. Excel cannot start an agent itself, so runs start on a schedule, an email, a chat request or a BigChange change.

questions

Excel questions

It writes the workbooks your office builds by hand every month. Centrus reads the jobs, quotes and invoices from your job system and writes them into an .xlsx in OneDrive, formatted and ready to send. People ask for one on the web, WhatsApp or Teams, and agents write the regular ones on a schedule.

Yes. Ask about the PPM tracker or the rate card and Centrus reads the sheet as rows, then answers with the row numbers it used. It can update those cells or add new rows underneath, so the tracker your team already opens stays the one they keep using.

A named person. In Agent Builder, an Approval step holds the run until someone approves it from the Runs panel or by email, and only then does Outlook send the workbook. In chat, nothing leaves the business until someone asks for it to be sent.

That AI only sees what lives inside Excel. It does not see your job system, your inbox, your client portals 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. Excel stays where the numbers live, and finance keeps opening the same files. Centrus reads workbooks in OneDrive and writes into them, so the report it builds is a normal .xlsx that opens in Excel Online or the desktop app.

Yes. The Excel step in Agent Builder adds a native column, bar, line or pie chart from a block of data on the sheet, and can turn the rows into a filterable table with a totals row. Each run redraws the chart with that month's figures.

Chat creates workbooks in the signed-in person's OneDrive. Agents can write to a folder path such as Reports/2026/September and create the file if it is missing. A workbook built in the chat can be saved into any OneDrive folder you name.

No. Excel, Word, Outlook and OneDrive are separate cards on Integrations, each with its own Microsoft sign-in. Agents connect Excel separately again, so a scheduled report keeps running while the person who built it is on holiday.

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 workbooks stay in your OneDrive.

A few things. Through Excel's online connection it cannot freeze panes, merge cells, add borders or set conditional formatting, so it tells you where to click instead. It does write the rows, formulas, number formats, charts and tables for you.

Excel comes with every plan, from £299.99 a month, at no extra cost. Chat uses message credits and agents use automation credits. Plans run month to month, with no lock-in, and paying annually saves 20%.See full pricing
