Monthly review · Expense reports

Build a month-end expense summary folder

At month-end most owners try to remember where the money went by scrolling a card statement, which tells you the amount but never the why or the receipt. A monthly folder that groups every expense record by category — and confirms each has its receipt attached — turns ten minutes of scrolling into a clean read-down. Cash Workspace gives you one folder per month where the whole package is ready to review and hand to your accountant.

The problem

Why month-end reviews feel like archaeology

Expenses arrive all month from different cards, vendors, and apps, and nothing groups them until you sit down to look. Then you're reconstructing a month from memory.

  • You can see a $3,200 card total but can't break it into software, supplies, and meals.
  • A few receipts are missing, and you only find out when the accountant asks for them.
  • The same expense got recorded twice across two tools, inflating the month.
  • There's no single thing to send the bookkeeper, so every month-end is a scramble.
  • Categories drift month to month, so you can't compare June to May.

The workflow

Assemble a review-ready monthly folder

Make a folder for the month, group records by category, confirm receipts, then mark it done.

  1. 1

    Create the month folder

    Name it clearly, e.g. "2026-06 June expenses", so each month stands alone and stays in date order.

  2. 2

    Group by category

    Sort the month's expense records into consistent categories: Software, Supplies, Meals, Travel, Advertising, Utilities.

  3. 3

    Confirm receipts attached

    Read down each category and check every record has its receipt or invoice attached; flag any that are missing.

  4. 4

    Chase the stragglers

    For any missing receipt, request a duplicate from the vendor and attach it before you close the month.

  5. 5

    Mark the month reviewed

    Once every record is categorized and has a receipt, note the folder as reviewed so it's ready for the accountant.

Record structure

What each expense record should carry into the summary

Consistent fields make the monthly read-down fast and the handoff clean.

Category
A consistent category — Software, Supplies, Meals — so the month groups the same way every time.
Vendor
Who you paid, so duplicates and recurring costs are obvious in the list.
Date
The transaction date, so the record lands in the right month.
Amount
The amount and currency, the figure the accountant will reconcile.
Payment method
A short note of which card or account it came from, to help match against statements.
Receipt attached
The receipt or invoice on the record — the one thing that makes the month review-ready.
Note
A brief note for anything unusual, e.g. "client lunch" or "annual renewal".

Example setup

An example monthly folder

One layout for a single month grouped by category.

Software & subscriptions

Each tool's monthly charge recorded with the invoice attached, e.g. hosting, design app, email.

Supplies

Office and operating supply purchases with receipts, vendor, and amount.

Meals & travel

Client meals and any trip costs, each with a receipt and a short purpose note.

Advertising

The month's ad-platform invoices recorded and attached, grouped for a quick total read.

Common mistakes

Mistakes to avoid

  • Closing the month with records that have no receipt attached, leaving gaps the accountant will bounce back.
  • Changing category names from one month to the next, so months can't be compared.
  • Recording the same charge in two places, which double-counts the month.
  • Waiting until tax season to assemble months you should have closed monthly.
  • Leaving a vague "misc" pile that nobody can later explain.

FAQ

Monthly expense summary FAQ

What makes a monthly folder review-ready?
Every expense is recorded with a consistent category, the right date and amount, and a receipt attached. When nothing is missing, the folder is ready to read down and hand off.
How long should a monthly review take?
Once expenses are recorded through the month, the end-of-month pass is mostly grouping by category and confirming receipts — usually a short sitting rather than a full reconstruction.
Can I send the folder straight to my accountant?
Yes. When the month is complete you can export the organized package so your accountant receives categorized records with receipts attached.
