| Date | Vendor | Amount | Status |
|---|---|---|---|

| 27 Feb | Grainger | $532.80 | No receipt |
Sixteen lines for the month; the six with no match (five shown here) are exactly what carries onto the next tab.
Missing List| Vendor | Amount | Above $75? | Risk |
|---|---|---|---|
| Grainger | $532.80 | Yes | High, needs a receipt |
| Home Depot | $276.53 | Yes | High, needs a receipt |
| Chili's | $86.42 | Yes | High, plus who attended |
| Lowe's | $124.99 | Yes | High, needs a receipt |
| Ace Hardware | $58.76 | No | High, needs a receipt |
| Shell | $68.40 | No | Low, a logged note closes it |
Five of the six gaps need an actual record, not just a note. The $75 exception covers the Shell fuel stop, a car cost, but not the Ace Hardware tools.

Organizing business receipts means every charge on your business card and bank statements has a record behind it, showing who you paid, how much, when and what you bought. In the US, the IRS asks for those details and suggests filing records by year and type of expense. What keeps the system honest is a monthly match: each statement line checked against its receipt, with the gaps listed while they're still easy to fix.
A statement line proves you paid. Only the receipt or invoice shows what you bought, and that's the half that goes missing.
The IRS's page on business records says your supporting documents should identify1 the payee, the amount paid, proof of payment and the date. They should also describe what you bought, in a way that shows it was for the business. One document may not cover it all.
Your card statement covers the first four. Publication 583, the IRS guide to keeping business records, is blunt about the rest: proof of payment alone doesn't establish that you're entitled to a deduction2. Keep the sales slip or invoice as well.
What each record proves
| Record | What it proves | What it leaves out |
|---|---|---|
| Statement line | Who you paid, how much and when | What you bought, and why |
| Itemized receipt | What you bought, where, when and for how much | The business reason, if it isn't obvious |
| Supplier invoice | What you were billed for, by whom and when | That you paid it, so keep the statement line too |
| Your written note | The business purpose, and who was at a meal | Proof of the amount |
Run all business spending through one account and one card. Publication 583 tells owners to keep the business account separate from personal checking. Once the two mix, every statement line turns into a question.
File records by year and type of expense, as the IRS suggests, with a folder for each month. Name each file with its date, vendor and amount, such as 2026-03-06 irrigation supplier 612.40.pdf, so a search finds it in seconds. If you file Schedule C, borrow its expense lines3 as categories (supplies, car and truck expenses, travel, meals) so year-end totals line up with the form.
Photograph paper receipts the day you get them, before they fade or vanish into a glovebox. Photos and scans count, but Publication 583 holds electronic records to the same rules as paper2: your system has to index them, keep them safe and reproduce them legibly.
Match once a month, so the job stays small and you still remember what each charge was for. For travel, meals, gifts and car use, keep a running log too. Publication 463 values a record made at or near the time of the expense4 over one written later, and counts a weekly log as timely.
Pull every statement
Download the month's statements for every business account and card. A bank statement converter turns PDF statements into rows.
Log every line
Give each transaction a row with its date, vendor, amount and category, whether or not a receipt exists.
Match the receipts
Mark a line matched only when the receipt or invoice is actually on file. Remembering one doesn't count.
List the gaps
Move unmatched lines to their own list, largest first, and write down each one's business purpose now.
Total by category
Add up spending and missing dollars per category. Gaps that cluster point to a habit, like one supplier or a personal card.
Do it the same week as your bank reconciliation, since both jobs start from the same statement.
You may have heard that receipts aren't needed under $75. The rule is real, but it lives in Publication 463, which covers travel, business meals, gifts and car expenses. For those, documentary evidence isn't needed for an expense under $754 unless it's lodging. You still need a written record of the amount, date, place and business purpose.
It doesn't stretch to supplies, parts, tools or software. Publication 583 singles out travel, transportation and gift expenses for special rules, and its list of records for other expenses sets no dollar floor. Keep the receipt for a $12 box of screws too.
What to keep, by type of expense
| Expense | What to keep | What's easy to miss |
|---|---|---|
| Supplies, parts, tools, software | The receipt or invoice, plus the statement line | The $75 exception doesn't apply |
| Travel away from home | Receipts for lodging and anything $75 or more, plus dates, destination and purpose | Lodging needs a receipt at any amount |
| Business meals | The restaurant receipt, who attended and the business reason | Most are only 50% deductible |
| Car expenses | A log of each business trip's date, destination, purpose and miles, plus the year's total miles | On the standard mileage rate, you can't deduct gas on top, but you can deduct parking and tolls |
For meals, Publication 463 accepts a restaurant receipt that shows the restaurant's name and location, the number of people served, and the date and amount. You or an employee must attend, so note who else was there and why.
Work from the largest gap down, starting with the vendor. Supplier portals, online order histories and your email often hold a copy, and a store may be able to look up a card purchase.
If no copy exists, write down what you bought and why from your calendar, job notes or messages, and file it with the statement line. Label it as reconstructed, and never pass it off as the original. When records of a travel, meal, gift or car expense are incomplete, Publication 463 accepts your own detailed statement plus other supporting evidence4.
March: 38 card and bank lines, $8,904.12 in total. Four have no receipt yet, $1,134.75.
Mar 6, irrigation supplier, parts, $612.40: download the invoice from the supplier's portal.
Mar 9, equipment rental, trencher, $388.00: save the emailed invoice to the March folder.
Mar 14, restaurant, client lunch, $96.20: request a copy, and note who attended and why.
Mar 21, hardware store, fasteners, $38.15: ask the store to look it up by card, or write a dated note naming the job.
The IRS's general rule is to keep records for 3 years5 after you file the return they support, and a return filed early counts as filed on its due date. Keep them 6 years if you left out income worth more than 25% of the gross income on your return, and 7 years if you claim a bad debt deduction.
Keep employment tax records at least 4 years after the tax is due or paid, whichever is later. Keep equipment records until the clock runs out on the return for the year you sell or dispose of it. Lenders and insurers may want records longer.
Before you close the month
When to bring in a tax professional
If you're rebuilding more than a few months of records, or the IRS has questioned a return, talk to a CPA or enrolled agent before you reconstruct anything. This guide is general information, not tax advice.
The template at the top of this page sets up the register, the missing-receipt list and the category totals, and River can fill them in from your own statement. At year end, the year-end tax package tool logs your CPA's requests and flags every unclear balance.
Use the files as they are, or open them in River. River asks for a card or bank statement and however you keep receipts today, whether that's a shoebox, an email folder or nothing yet. It logs every line with a category, marks which ones have a real receipt, and builds the missing-receipt list and category totals from your own month.
When a receipt turns up later, send a photo or its details and River matches it to the right line by date, vendor and amount, then updates the totals. It won't treat a rebuilt record as an original, and it leaves audit questions to your accountant.
Download two Word documents and three CSV sheets at no cost, or open the whole set in River and fill it in with AI.
Log each card and bank line in the Expense Register yourself, or send River the statement to build it.
Mark a line as having a receipt only when a real document exists. Everything else lands on the Missing Receipt List.
Chase the largest gaps first, note who attended each meal, and check the Category Summary for a habit to fix.
Give every receipt a place by year, month and type of expense, and label each file with the date, vendor and amount. Once a month, check each line on your business card and bank statements against a receipt, list the ones missing, and chase the biggest gaps while the details are fresh.
For supplies, parts, software and other everyday costs, keep a receipt or invoice at any amount, because a statement only proves you paid, not what you bought. The exception for amounts under $75 covers only travel, business meals, gifts and car costs (never lodging), and even then you need a written record of the details.
Generally, yes. The IRS applies the same rules to electronic records as to paper, so a photo or scan has to be complete, readable and easy to retrieve when asked. Check that each photo is readable before you throw the paper away, and back the folder up somewhere other than your phone.
At least 3 years after you file the return they support, under the IRS's general rule. That stretches to 6 years if you underreport income by more than 25% of the gross income shown, and 7 years for a bad debt deduction. For equipment, the clock starts with the return for the year you sell it.
Ask the vendor for a duplicate first, or search your email and online order history for a copy. If nothing turns up, rebuild the details in a dated note, mark it reconstructed and keep it with the card or bank line. Publication 463 also lets a statement like that, backed by other evidence, prove a travel, meal, gift or car cost.
Yes. The two Word documents and three CSV sheets download free, with no account or signup. The sheets arrive filled in with a made-up HVAC business, so you can see how they fit together before clearing them. Edit with AI opens the same files in a free River workspace.
It opens the template in a free River workspace, where River turns your own statement into the Expense Register. Send the statement and whatever receipts you have, in any form. River marks which lines are backed by a receipt, lists the gaps, totals them by category and suggests how to close each one. When a receipt turns up, it updates the sheets.
