Solo finance · Month-end close

Close out the month's invoicing cleanly

At the end of a busy month, it's easy to leave a finished project uninvoiced, an invoice without a status, or a paid one sitting outside its folder. By the time the accountant asks, the trail is cold. A repeatable month-end close checklist makes sure every piece of the month's invoicing is recorded, statused, filed, and carried forward correctly. Cash Workspace gives you one monthly folder where you can run that checklist and leave the month complete.

The problem

Why month-end invoicing slips through the cracks

Without a fixed close routine, the last few days of the month are the easiest place for invoicing to fall apart.

  • Work was delivered on the 28th but never got invoiced before the month rolled over.
  • Several invoices have no status, so you can't tell what's still owed.
  • Paid invoices are scattered instead of filed in the month's folder.
  • Outstanding invoices from this month aren't flagged to follow up next month.
  • When the accountant asks for the month, the folder is half-empty.

The workflow

Run the same close checklist every month

Work through these steps on the last business day so the month closes complete and consistent.

  1. 1

    Confirm all work is invoiced

    Check every completed project and deliverable this month has an invoice issued, and create any that are missing.

  2. 2

    Give every invoice a status

    Make sure each invoice is marked draft, sent, partially paid, paid, or overdue — no blanks.

  3. 3

    File the paid invoices

    Move every paid invoice into this month's folder with its payment confirmation attached.

  4. 4

    Carry outstanding forward

    Flag invoices still unpaid so they appear on next month's follow-up list.

  5. 5

    Check the folder is complete

    Confirm the monthly folder holds every invoice, PDF, and confirmation the accountant would expect.

Record structure

What to confirm for each invoice at close

Run down these fields for every invoice so nothing is left ambiguous when the month closes.

Work invoiced
Every delivered project or task this month has a matching invoice.
Invoice number
Each invoice has a number in your sequence with no gaps or duplicates this month.
Status
Draft, sent, partially paid, paid, or overdue — set on every invoice.
Issue date
Confirms the invoice belongs to this month's books.
Payment confirmation
For paid invoices, the confirmation attached to the record.
Outstanding flag
Unpaid invoices marked to carry into next month's follow-up.
Filed location
The invoice and its PDF sit in this month's folder.

Example setup

An example month-close folder

One way to lay out the close for a single month inside your workspace.

June 2026 — invoiced

Every invoice issued in June, each with a number, status, and dates.

June 2026 — paid

Paid invoices with payment confirmations attached, ready for the accountant.

June 2026 — carried forward

Still-unpaid June invoices flagged to follow up in July.

June 2026 — close note

A short note confirming all work invoiced, all statuses set, folder complete.

Common mistakes

Mistakes to avoid

  • Rolling into the new month with delivered work still uninvoiced.
  • Leaving invoices without a status, so outstanding amounts are invisible.
  • Filing paid invoices loosely instead of into the month's folder.
  • Not flagging this month's unpaid invoices to follow up next month.
  • Skipping the final folder check, so the accountant gets an incomplete month.

FAQ

Month-end invoice close FAQ

When should I run the close?
On the last business day of the month works well, so every invoice issued during the month is captured before the next one starts.
What if an invoice is still partially paid at close?
Mark it partially paid, note the remaining balance, and carry it forward so it appears on next month's follow-up. The month still closes cleanly with its status accurate.
Does Cash Workspace close the month automatically?
No. You run the checklist yourself; Cash Workspace gives you the monthly folder, statuses, and exports to make each close fast and consistent.
