Receipts and statements arrive as email attachments from a dozen clients, in a dozen shapes. The way to keep up is to give each client one route, then move each file the day it lands. One route means one address to send to and one subject line. Moving the file means it goes into the books or into the client’s folder, under a name that says what it is. The email stays behind as the record of who sent it and when.
Most of the work is in setting that up once. After that, a month of attachments takes minutes a day.
- Pick one route per client. Your address, a receipts alias, or your software’s own capture address. One, not three.
- Ask for one subject line. “Lakeside · receipts · September” sorts itself and searches itself.
- Rename the file when you save it. Client, month, vendor, amount. The name answers the question later.
- Send each file to its home the same day. Receipts go on a transaction. Statements go in the month’s folder.
- Treat a missing attachment as a question. A link, a login or a photo of a screen each have a fix.
What arrives, and what each one needs
A bookkeeper’s inbox gets the same few kinds of attachment every month. Each one has its own usual snag.
| What arrives | How it usually comes | The usual snag | What to do with it |
|---|---|---|---|
| A photo of a paper receipt | Phone camera, sent from the client’s phone | Three receipts in one photo, or a blurry total | Ask for one receipt per photo |
| A vendor’s email receipt | Forwarded by the client | The receipt is in the email body, with no file | Print the email to PDF |
| A supplier’s PDF invoice | Forwarded, or sent to you directly | It’s a bill to pay, mixed in with receipts | Enter it as a bill, not an expense |
| A bank or card statement | A “your statement is ready” email | The PDF sits behind the bank’s login | Ask for the PDF, or a feed |
| A payroll register | From the payroll provider, or forwarded | Password-protected, or a link that expires | Save it the day it comes |
| A spreadsheet export | The client’s own sales or tips report | Columns change from month to month | Keep last month’s as the model |
| A forward with ten files | The client clearing their inbox | No words above it, no month named | Ask which month, once |
The pattern underneath is simple. The file is what you need. The email is the context: who sent it, when, and what they said about it. Keep both, and keep them linked.
Email attachments for bookkeepers start with one route per client
The biggest time cost is not knowing where a file went. A receipt that might be in your inbox, the client’s sent mail, a shared drive or a text message is four searches. A receipt that has one route is one.
There are three routes that work, and each client gets one of them.
Your own address, with a fixed subject. This suits clients who send a handful of files a month. They reply in the same thread each month, so everything for September sits together. How to split your own address from role addresses is in email management for bookkeepers.
A receipts alias. An address like receipts@yourfirm.com that lands in a folder you clear once a day. This suits clients who send many small receipts. It keeps them out of the mail that needs a reply.
Your bookkeeping software’s capture address. QuickBooks Online and Xero both give you an address that turns an emailed receipt into a draft transaction. This suits clients with dozens of receipts a month. More on these near the end.
Then tell the client, once, in writing. A note like this sets the routine for the year:
Hi Maria,
To keep September (and every month after) simple:
- Send receipts to receipts@harborbooks.com
- One receipt per photo, with the total in frame
- Put "Lakeside · receipts" and the month in the subject
- Bank and card statements: forward the PDF, not the
"your statement is ready" email
That's it. I'll confirm anything I can't match by the 5th.
Thanks,
SamThe last line matters. It tells the client when they’ll hear from you, so they don’t send the same receipt twice to be safe.
The file name that answers questions later
An attachment called IMG_4471.jpg or Statement.pdf tells you nothing in March. Rename it as you save it, in the same order every time:
client_YYYY-MM_vendor_amount.ext| As it arrived | Renamed |
|---|---|
IMG_4471.jpg | lakeside_2026-09_harbor-print_318.40.jpg |
Statement.pdf | lakeside_2026-09_chase-checking-4410_statement.pdf |
invoice (3).pdf | lakeside_2026-09_jsmith-design_650.00.pdf |
Payroll Register 09.15.pdf | lakeside_2026-09-15_payroll-register.pdf |
Four habits keep the names useful.
- Year first, then month. Files sort in date order in any folder.
- Lowercase, with hyphens. No spaces, no ampersands, no slashes.
- The amount with its cents. It’s the same number you’ll search the feed for.
- The last four of the account on statements. Clients with two cards will thank you.
The plain characters aren’t only tidiness. Intuit’s QuickBooks Online attachments help says this about file names:
“Attachments can’t contain special characters in the file name.”
A name with an ampersand or a slash can fail on upload. A name built from letters, numbers and hyphens goes through.
Where each file goes next
Once a file is named, it has one of three homes. Deciding which one takes a second.
Receipts and bills go on the transaction. A receipt explains one line in the feed. Attach it to that line in your bookkeeping software, and write a one-line memo. The steps, and what to write in the memo, are in explaining a charge.
Statements go in the month’s folder. A statement covers the whole month. It’s what you reconcile against. Keep it in the client’s folder for that month, beside the reconciliation report.
Reports go with the run they belong to. A payroll register belongs with that pay date. A sales export belongs with the month’s revenue entry.
Then archive the email, or label it done. The file now lives where you’ll look for it. The email lives where you’ll look for the context. If someone asks “who sent this, and when?”, one search for the file name’s vendor and month brings the thread back.
A week of attachments, one desk
Here’s what a normal week looks like for a bookkeeper with eleven clients, from Monday, September 28, 2026, to Friday, October 2.
| Day | What arrived | From | What happened to it |
|---|---|---|---|
| Mon | 9 receipt photos, one email | Lakeside Bakery | Renamed, attached to 9 card lines, 20 minutes |
| Mon | “Your statement is ready” | Northside Dental’s bank, forwarded | Asked for the PDF. Arrived Tuesday |
| Tue | Payroll register, password-protected | Payroll provider, for Coastline Landscaping | Saved and renamed the same morning |
| Tue | A forward with 6 PDFs and no words | Reyes Plumbing | One reply: “Are these all September?” |
| Wed | Supplier invoice, net 30 | Copied to you by Harbor Print | Entered as a bill for Lakeside, not an expense |
| Wed | A Google Drive link, not a file | Bright Path Tutoring | Downloaded, renamed, saved. The link can expire |
| Thu | 22 receipts to the capture address | Coastline Landscaping | Reviewed and matched in the software |
| Fri | A receipt in the email body | Amazon order, forwarded by Northside | Printed to PDF, attached to the card line |
Two things stand out in a week like this.
Most of it is quick. Lakeside’s nine receipts took twenty minutes because they came the agreed way: one email, one receipt per photo, the month in the subject.
The slow ones are the ones without a route. Reyes Plumbing’s bare forward and Northside’s bank notice each cost a round trip. Both clients got the routine note that week.
When the attachment isn’t there
Sometimes the email arrives and the file doesn’t. Each case has its own fix.
The file became a link. Big attachments get swapped for a cloud link. Google’s Gmail Help says personal accounts have a 25 MB limit, and explains what happens past it:
“If your total attachment size is greater than the limit, Gmail automatically removes the attachment and adds it as a Google Drive link in the email.”
Microsoft mailboxes default to 35 MB for sending and 36 MB for receiving, and an administrator can change that. A client’s year of scanned statements will pass those limits fast. Download what’s behind the link the day it comes, because the client can revoke the share or tidy the folder.
The statement is behind a login. Most banks send a notice, not the statement. Chase’s paperless statements page describes it this way:
“To see your statements, sign in and click the Main Menu icon in the top left corner of your screen. Choose ‘Statements & documents’ to access statements for all of your accounts.”
So the forwarded notice is only a reminder. Ask the client to download the PDF and send it. Better still, ask whether you can have your own view of the account, so you don’t need either. Chasing a late statement is in the missing statement.
The receipt is the email. Many online vendors send the receipt as the body of the email, with no file. Print it to PDF and name it like any other receipt.
The forward has nothing written above it. Six files and no month. Don’t guess. Ask once, in the same thread, and put your question in the subject so the answer lands with the files.
The file is password-protected. Payroll registers and some bank statements come this way. Where the password should live, and what a client expects of you with bank data in your mail, is in bank data in a thread.
Replying, forwarding and sending files back
Attachments travel out as well as in. Two snags come up often enough to be worth knowing.
Outlook’s Reply leaves the attachments behind. When you reply to a client’s email in Outlook, their files don’t come along. Forward does carry them. Answers on Microsoft Q&A say there’s no built-in way to keep them on a reply, short of custom code in classic Outlook. So when you need to send a client’s receipt on to their accountant with a note, forward it. When you need to answer the client about the receipt, reply, and name the file in your first line.
QuickBooks doesn’t send the attachment unless you tick the box. When you attach a file to an invoice in QuickBooks Online, it stays on the invoice in the books. A QuickBooks Team answer on Intuit’s community forum explains:
“When adding an attachment to a Sales or Expense form, you’ll see a checkbox for ‘attach to email.’”
Check that box and the file goes out with the invoice. Leave it clear and it stays private to the books. For clients who invoice from QuickBooks, this is usually the answer to “the customer says the timesheet wasn’t attached.” Intuit’s attachments help also notes that PDF attachments can’t currently be added to statements sent to customers.
Finding last March’s statement
When the file was named and saved the day it came, you find it in the folder. When it wasn’t, you search the mail. Two searches cover most cases:
- Gmail:
from:maria@lakesidebakery.com has:attachment filename:pdf after:2026/03/01 before:2026/04/15 - Outlook:
from:maria@lakesidebakery.com hasattachment:yes, then narrow by date
The full set of searches, and why the amount is usually the best search term, are in explaining a charge.
The attachment that isn’t from your client
Invoices and statements are what fraud imitates. A “supplier” sends a PDF invoice with new bank details. A “bank” sends a statement that opens a login page. The FBI’s Internet Crime Complaint Center titled one public service announcement Business Email Compromise: The $55 Billion Scam. It put exposed losses worldwide at about $55.5 billion.
The habit that protects you is ordinary. When a vendor’s payment details change in an attachment, confirm by phone, at a number you already have. When a statement arrives from somewhere it never came from before, open the bank’s site yourself. How to keep a hostile message away from the software reading your mail is in when an email is written for the AI.
How Point keeps the files from your mail
Point reads the Gmail or Microsoft 365 account you already use. When attachments arrive, they don’t disappear into threads.
- The files gather in one list. Documents collects the attachments from your mail, named and dated. Each file’s card shows the thread it came from, one click away.
- You can ask about a file without opening it. “What’s the closing balance on Lakeside’s September statement?” Point reads the PDF and answers, with a link back to the file (questions of attachments).
- Point can wait for the statement for you. Tell it, in plain words, “Let me know when Northside’s September bank statement arrives.” Point checks each incoming message and tells you when it lands (notify me when).
- Suspicious mail is held apart. A message built to trick the software reading it goes to quarantine, unprocessed. You decide whether it comes out.
Point keeps the file and its email together. Your bookkeeping software is still where the receipt meets the transaction. More on what Point does is on the benefits page.
When a capture app fits better
For a client who sends dozens of receipts a month, email to your own address is the slow route. Your bookkeeping software’s capture address does the reading for you.
QuickBooks Online gives you a forwarding address ending in @assist.intuit.com. Intuit’s email receipts and bills help sets out what it accepts:
- PDF, JPEG, JPG, GIF or PNG files
- Each attachment between 46KB and 20 MB
- Several receipt images in one email, with one receipt per image
- Sent from the email address the user signs in to QuickBooks with
QuickBooks then pulls the date, amount, vendor and last four card digits, and you review and match. The last rule is the one that trips people up. A client who forwards from a different address than their QuickBooks login won’t get through.
Xero says on its document capture page that you can “forward a supplier’s bill to your Xero email.” It reads receipts, invoices and rent statements and fills in the record for you to check.
For a client with five receipts a month, none of this is needed. One thread a month and a file name do the job.
Common questions
How should a bookkeeper organize email attachments from clients?
Give each client one route for files: your address with a fixed subject, a receipts alias, or your software’s capture address. Rename each file as you save it, as client, year and month, vendor and amount. Attach receipts to their transactions and keep statements in the month’s folder. Then archive the email, so the inbox holds only what still needs you.
Why doesn’t Outlook include attachments when I reply?
Outlook’s Reply and Reply All don’t carry the original message’s attachments. Forward does. Answers on Microsoft Q&A say there’s no built-in setting to change this, short of custom code in classic Outlook. Forward the message when the files need to go on, and reply when you’re answering about them.
Why isn’t QuickBooks attaching my file to the invoice email?
In QuickBooks Online, a file attached to an invoice stays in the books unless you check “attach to email” beside it. A QuickBooks Team answer on Intuit’s community forum describes that checkbox. Check it before you send. Intuit’s help also says PDFs can’t currently be attached to customer statements.
What’s the attachment size limit in Gmail and Outlook?
Google says personal Gmail accounts can attach up to 25 MB, and anything larger becomes a Google Drive link. Microsoft’s default for Microsoft 365 mailboxes is 35 MB to send and 36 MB to receive, and an administrator can change it. Download linked files the day they come, because links can stop working.
Can a client throw away a paper receipt once they’ve emailed a photo of it?
The IRS allows it under conditions. Revenue Procedure 97-22, section 7, permits destroying original paper records once the electronic storage system has been tested and procedures are in place to keep it compliant. The copy has to be complete and legible, and kept as long as the IRS says to keep records. The IRS’s general period is three years, and four years for employment tax records. If a client wants to go paperless, the photo has to show the whole receipt clearly.
Should clients email bank statements to their bookkeeper?
Many do, and it works best when they send the PDF itself, not the bank’s “your statement is ready” notice. A read-only view of the account, or a bank feed into the books, removes the email altogether. What a client expects of you when bank data does arrive by email is in bank data in a thread.
