The Scenario
You are an agency billing manager. It is the first Monday of the month and client invoices go out Friday. You have eight client projects in ClickUp, and last month's time entries are scattered across all of them.
Your process: pull every time entry from the past 30 days, group by client project, multiply hours by each client's billing rate, and produce a draft invoice total per client. That review takes you two and a half hours every month.
The slow version:
- You open ClickUp's time tracking reports, filter by date range, export the CSV
- You open the CSV in Google Sheets and realize the project column is an ID, not a name
- You go back to ClickUp to find the project names and paste them in manually
- You build the billing summary table with SUMIF formulas, eight clients, eight rows
- You check the rates tab and cross-reference each client's hourly rate
- You email a draft to the account manager who points out two projects are miscategorized
- Friday arrives and the invoices are half-built.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that fetches ClickUp time entries, groups them, and calculates billing totals in the same operation.
Open the SheetXAI sidebar and type:
Fetch all ClickUp time entries from the workspace in cell A1 for the date range in cells B1 and B2. Write user, project name, task name, duration in hours, and billable flag into columns A through E. Then create a summary table on a new tab called "Billing Summary" that groups by project name, shows total hours and billable hours per project, and multiplies billable hours by the rate in the Rates tab matched by project name.
SheetXAI calls the ClickUp API, pulls all time entries for the date range, resolves project names from the workspace, populates the raw data tab, and builds the Billing Summary tab with the calculated totals.
What You Get
Two outputs from one prompt:
- Raw time entries tab — every time entry with user, project, task, hours, and billable flag
- Billing Summary tab — one row per client project showing total hours, billable hours, hourly rate, and draft invoice total
The Billing Summary is calculation-ready. Billable hours times the rate from the Rates tab equals the draft total for each client. You send the Billing Summary to the account manager for review, not a raw ClickUp export.
What If the Data Is Not Quite Ready
Time entries pulled from ClickUp across eight projects rarely arrive in perfect billing shape. SheetXAI handles the edge cases in the same prompt.
When some time entries are not linked to any task
Unstructured time entries exist in ClickUp without a parent task. They still belong to a project and should be included in the billing.
Fetch all ClickUp time entries from the workspace in cell A1 for the date range in B1 and B2. Include entries not linked to a task and label them as "General" in the task column. Write user, project, task, hours, and billable flag into columns A through E.
When the Rates tab uses project display names but ClickUp returns internal project IDs
The Rates tab has project names like "Acme Corp — Web Redesign" but ClickUp's API returns a project ID. The mapping lives in a Lookup tab.
Fetch all ClickUp time entries for the date range in B1 and B2. For each entry, look up the project name from the Lookup tab using the project ID. Write user, project name, task, hours, and billable flag into columns A through E. Then build the Billing Summary using the matched project names and the rates from the Rates tab.
When some hours should be excluded from billing
The client contract for one project caps billable hours at 40 per month. Any hours logged above 40 for that project are non-billable.
Fetch all ClickUp time entries for the date range in B1 and B2. For the project named "Meridian Rebrand," cap billable hours at 40. Mark any hours above 40 as non-billable. For all other projects, use the billable flag from ClickUp. Write the raw data into columns A through E and build the Billing Summary on a new tab.
When you need the full billing package in one pass: raw entries, summary, and a narrative for each client
The account manager wants a one-sentence description of the work done per client this month, to include in the invoice email.
Fetch all ClickUp time entries from the workspace in cell A1 for the date range in B1 and B2. Write the raw entries into columns A through E. On the Billing Summary tab, calculate total and billable hours per project using rates from the Rates tab. In the cell next to each project's total, write a one-sentence plain-English summary of the work done for that client based on the task names logged this month.
The pattern: the data fetch, the calculation, and the narrative summary all happen in one prompt. The billing package arrives ready to review, not ready to start building.
