Free Simple Invoice Spreadsheet Template for Google Sheets & Excel
Ten line items, each with a description, a quantity and a rate, and a category so one kind of work is tellable from another. The Free Simple Invoice spreadsheet template holds the tax rate in a cell of its own rather than buried inside a formula, and works out the subtotal, the tax and the TOTAL DUE as you type. A complete invoice on one working sheet, How to Use on a second. Google Sheets or Excel. No macros, no VBA, no sign-up.
The FinancialAha Free Simple Invoice Spreadsheet Template is a one-sheet workbook for Google Sheets and Excel, with a How to Use guide on a second tab. It works as a Free Simple Invoice Excel template and a Free Simple Invoice Google Sheets template from the same download. Line items with quantities and rates, a category on each, a tax rate you set, and a total the client can pay from. No macros, no VBA, no sign-up.
Inside the workbook
What's inside the FinancialAha Free Simple Invoice spreadsheet template
The FinancialAha Free Simple Invoice Spreadsheet Template runs on a single working sheet, with the instructions on a tab of their own. It works in both Microsoft Excel and Google Sheets and here is what the Free Simple Invoice spreadsheet holds.
01of 01
Invoice
Your business at the top, the client beside it, and the invoice's own details - number, date, due date and payment terms - underneath. Then the line items, each carrying a description, a category, a quantity and a rate, with each line total worked out and everything summed at the foot.
The word simple in the name is doing real work here. There is no discount field, no payment block and no terms; what there is, is the four things an invoice has to have to be paid - who it is from, who it is to, what it is for, and by when. Everything else is an addition rather than a requirement, and a document that asks for less gets sent more often.
The category column is optional in practice. It exists so that a client paying several invoices, or you looking back at a quarter, can tell design work from hosting without reading every description.
The tax rate sits in its own cell rather than inside the formula, because the right rate depends on where you are and what you sell.

Included guide
How to Use
A step-by-step guide on its own tab, covering how to replace the sample values, how the tax rate cell works, and how to change the currency. Because it ships inside the file, the instructions travel with the template wherever it is opened.
Works in both Google Sheets and Excel

Opening the Free Simple Invoice spreadsheet Excel file
Nothing in the Free Simple Invoice Excel template is version-specific, so this Free Simple Invoice spreadsheet Excel workbook behaves identically in Excel on Windows, Excel on Mac, and older builds.
The FinancialAha Free Simple Invoice Spreadsheet Template covers the job: itemised lines, a tax rate you set and a total due. The Essentials Simple Invoice Spreadsheet Template for Google Sheets and Excel records the client with a company and an email, adds a discount field taken off before the tax is worked out, and carries blocks for payment instructions and for notes and terms.
Notes on working in the Free Simple Invoice spreadsheet template
The line total is quantity times rate, so a flat fee goes in as one at the full amount.
Blank line rows return nothing rather than a zero, so a three-line invoice prints as three lines.
The tax rate sits in a cell of its own and the tax line reads the subtotal against it.
Both halves of the header are sample text - the business sending the invoice and the one receiving it.
One invoice per file, in both tiers. Tracking which invoices have gone out and which have come back is what an invoice tracker is for.
The dropdown beside the title relabels the rate and total columns. It changes the label and nothing else.
How the Simple Invoice template works
The Free Simple Invoice Spreadsheet Template is the document you send after a job. Your business sits at the top, the client beside it, and the invoice details - number, date, due date and payment terms - underneath. The line items follow with a description, a category, a quantity and a rate, each line totalled, then a subtotal, tax and the total due. The word simple is doing real work: there is no discount field, no payment block and no terms, just the four things an invoice needs to be paid.
When this template helps
01
You have finished a job and need a document the client can pay from.
02
You want the tax rate to be a field rather than a formula edit.
03
You invoice occasionally and do not want a billing subscription for it.
04
You need a PDF-ready layout that works the same in Excel and Google Sheets.
Tips to get the most out of it
Quantity times rate covers most shapes of work: a fee is one at the full amount, an hour is hours at an hourly rate, a product is units at a unit price.
The category column is what keeps a mixed invoice readable when the lines are not all the same kind of work.
The due date and the payment terms say the same thing two ways, and an invoice carrying both is harder to argue with.
Common mistakes to avoid
Reusing an invoice number. It is the reference a client quotes when they pay, and two invoices sharing one makes a payment impossible to match.
Leaving the sample business details in the header before sending.
Leaving the due date blank, which turns a payment date into a matter of opinion.
Keeping one file and overwriting it per job. A copy per invoice is what makes a later question about what was charged answerable.

Frequently Asked Questions
What is the difference between the free and Essentials Free Simple Invoice spreadsheet template?
Free is a single-sheet starter template with sample data and a How to Use guide. Essentials ($19) is the fuller build - more capacity, more detail, and more worked out for you rather than typed. This template has no Ultimate build. What each tier holds differs by template - the comparison table on every template page lists it exactly.
Which Free Simple Invoice spreadsheet template should I download?
Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.
Can I upgrade the Free Simple Invoice spreadsheet template later?
Essentials is a one-time $19 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.
Is the FinancialAha Free Simple Invoice Spreadsheet Template a Google Sheets template?
Yes. Upload the file to Drive and choose "Open with Google Sheets". Nothing needs rewriting in the Free Simple Invoice Google Sheets template, and Sheets exports to PDF in a couple of clicks, which is one way an invoice reaches a client.
Is the FinancialAha Free Simple Invoice Spreadsheet Template an Excel template?
Yes. The download is a plain .xlsx, so the Free Simple Invoice Excel template opens directly in Excel with no import step. There are no macros and no VBA in the file.
Will the FinancialAha Free Simple Invoice spreadsheet Excel file open in older versions of Excel?
Yes. The Free Simple Invoice spreadsheet Excel workbook ships as a plain .xlsx, so it opens identically in current Excel and in builds that predate dynamic arrays.
What makes the Free Simple Invoice spreadsheet template simple?
What is not on it. There is no discount field, no payment block and no terms - just who it is from, who it is to, what it is for and by when. A document that asks for less gets sent more often.
Can I change the tax rate in the Free Simple Invoice spreadsheet template?
Yes. It is a cell rather than a figure inside the formula, so a different rate takes one edit and the tax and total due follow.
How do I apply a discount on the Free Simple Invoice spreadsheet template?
By adjusting a rate, or by adding a line at a negative amount. A discount field of its own, taken off before the tax is worked out, is on the Essentials build.
How many line items does the Free Simple Invoice hold?
Ten, the same as the Essentials Simple Invoice. What changes between tiers is the columns, not the row count - Essentials drops the per-line category column and adds a discount field instead.
Does the FinancialAha Free Simple Invoice spreadsheet track which invoices have been paid?
No. This is the document you send, one file per job. Following which of them have been paid is what an invoice tracker is for.
How do I open the Free Simple Invoice spreadsheet template in Google Sheets?
Upload the .xlsx file to Google Drive, then open it with Google Sheets. All formulas and formatting will be preserved.
Can I use the Free Simple Invoice spreadsheet template for commercial work?
