A Google Sheets client billing sheet answers one practical question: what should the client be billed for approved work? The sheet usually starts with date, client, project, description, start time, end time, billable status, billing rate, and rounding rule. For duration rows based on start and end datetimes, Google Sheets stores time as decimal days, so the elapsed value must be multiplied by 24 to become billable decimal hours.
The result is a pre-tax invoice amount by client, project, person, task, or rate category. A U.S. sheet should keep tax as a jurisdiction-specific input because the United States has no federal VAT/GST or national sales-tax rate for billed professional time. State and local treatment controls whether a service is taxable and what percentage applies.
The core formula is billable hours multiplied by the billing rate. In Google Sheets, a duration from end time minus start time needs the structure `(end - start) * 24`, then a billing rule can round it. `MROUND(hours, 0.25)` rounds to the nearest quarter hour, while `CEILING(hours, 0.25)` rounds positive time up to the next quarter hour when the client agreement requires upward rounding.
For example, a client migration sheet has 17 approved architecture hours at $190 per hour and 23 approved build hours at $115 per hour. The architecture line is $3,230, and the build line is $2,645. The pre-tax invoice subtotal is $5,875. If tax applies, add the state or local percentage as a separate input after the billable subtotal, not as a hidden part of the hourly rate.
Google Sheets is useful when you need a transparent, editable billing model. Use bracketed elapsed-hour formats such as `[h+]` or `[hh]` for duration totals so 27 hours displays as 27 hours, not as a clock time. Use separate columns for raw duration, rounded billable hours, rate, line amount, tax code, and invoice status so formula errors are easier to locate.
The main boundary is billable status. Time tracked directly from a Google Sheet through Everhour's website integration appears with the sheet title, editable reported time, and a quick link back to the Google file, but it is not billable until the entry is added to an existing task in an internal or connected project. In Sheets-only workflows, you need an equivalent approval or billable-status column before totals are sent to the client.
A one-off Google Sheets calculation is enough for a short engagement, a single client, or a quick check before sending an invoice draft. It handles the math, supports rounding functions, and can feed a template that exports invoice PDFs from spreadsheet data. It is also practical when the billing rule is simple: approved hours, one rate table, one subtotal, and one jurisdiction-specific tax input.
A managed workflow becomes necessary when multiple people submit time, rates change by project or person, non-billable work must be excluded, or invoices need status tracking after export. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates amounts from rates while excluding non-billable tasks, and exports invoice drafts to QuickBooks Online, Xero, or FreshBooks.

Subtract the start datetime from the end datetime, then multiply the result by 24. Google Sheets stores date and time values as decimal days, so the multiplication converts the duration into billable decimal hours. Use an elapsed-hour display format such as `[h+]` or `[hh]` when totals can exceed 24 hours.
Use `MROUND(hours, increment)` when the billing rule rounds to the nearest increment, such as 0.1 hours or 0.25 hours. Use `CEILING(hours, increment)` when the contract or policy says positive time must always round up to the next increment. Do not mix the two in one client total unless the rate agreement says so.
No. Keep tax outside the hourly rate column. The United States has no federal VAT/GST or national sales-tax rate for billed professional time, and state or local rules decide whether a service is taxable. Put tax in a separate jurisdiction-specific input after the billable subtotal.
The common mistake is displaying a duration total as clock time. Without an elapsed-hour format, totals over 24 hours can appear as a time of day instead of total billable hours. Use bracketed elapsed-hour tokens such as `[h+]` or `[hh]` so the visible total matches the billing calculation.
Yes. Google's Apps Script invoice sample shows a workflow that populates an invoice template sheet from spreadsheet data, exports the invoice as a PDF to Google Drive, and can email the PDF from the sheet through a custom menu. The sheet still needs correct billable hours, rates, rounding, and tax inputs first.
Everhour Billing & Invoicing turns tracked billable time and expenses into invoices, calculates invoice amounts from rates, and excludes non-billable work. Invoice drafts can be exported to QuickBooks Online, Xero, or FreshBooks, with invoice status, number, issue date, and amount visible back in Everhour.
Use Google Sheets for one-off billing math, then move recurring client billing into Everhour when tracked billable time, rates, non-billable exclusions, and accounting exports need invoice-ready tracking.
