Organize client-reimbursable expenses

When you bill costs back to clients — travel, materials, subcontractor fees, courier charges — those pass-through expenses are easy to forget to invoice, and forgotten reimbursables come straight off your own pocket. Tagging each reimbursable to the client it belongs to, attaching the receipt, and tracking whether it's been billed keeps every dollar accounted for. Cash Workspace gives you one place to record reimbursable expenses, attach receipts, and see billed vs. unbilled per client.

The problem

Why reimbursable costs go unbilled

Pass-through costs get paid in the moment — a flight, a supply run, a courier — and then disappear into general expenses. Without a client tag and a billed marker, they never make it onto an invoice.

  • A reimbursable travel cost gets paid and never lands on the client's invoice.
  • You can't tell which receipts are pass-through costs versus your own overhead.
  • Two clients' reimbursables blur together with no client tag.
  • The receipt for a billable material is gone when the client questions the charge.
  • At invoice time you're guessing which costs are still unbilled.

The workflow

Tag, attach, then bill it back

Mark each reimbursable to its client at the moment of spend, then list those costs on the client's invoice and mark them billed.

  1. 1

    Record the cost

    Enter each pass-through expense with its date, vendor, category, and amount as soon as you pay it.

  2. 2

    Tag the client

    Add the client tag so the cost is tied to the client you'll bill it back to.

  3. 3

    Attach the receipt

    Attach the receipt so you can show the client exactly what was charged.

  4. 4

    Mark reimbursable status

    Tag the expense as reimbursable and unbilled until it appears on an invoice.

  5. 5

    Bill and mark billed

    List the reimbursable costs on the client's invoice, then mark each one billed so it isn't charged twice.

Record structure

What to record for each reimbursable expense

These fields keep every pass-through cost tied to a client and a billing status.

Date
When the cost was paid, so it lands on the right invoice.
Client tag
Which client this reimbursable will be billed back to.
Vendor
Who was paid — airline, supplier, courier, or subcontractor.
Category
An expense category such as travel, materials, or subcontractor cost.
Amount
The total paid and currency, to appear on the invoice.
Reimbursable
A tag marking this as a pass-through cost rather than overhead.
Billing status
Unbilled or billed, so you know what still needs invoicing.
Receipt
The receipt attached so you can back up the charge to the client.

Example setup

An example reimbursable folder setup

One way to keep pass-through costs organized per client.

Client: Acme — reimbursables

Travel, materials, and courier costs tagged to Acme, each with a receipt and a billed/unbilled marker.

Client: Blue Co — reimbursables

Pass-through costs tagged to Blue Co, each with a receipt and billing status.

Unbilled reimbursables

A filtered view of every reimbursable not yet on an invoice, across clients.

Common mistakes

Mistakes to avoid

  • Paying a billable cost and forgetting to put it on the client's invoice.
  • Not tagging the client, so reimbursables can't be sorted by who owes them.
  • Skipping the receipt, leaving you unable to back up the charge.
  • Mixing pass-through costs with your own overhead under one category.
  • Failing to mark a cost billed, so it gets charged to the client twice.

FAQ

Reimbursable expense organizing FAQ

How do I make sure every billable cost gets invoiced?
Tag each reimbursable to its client and mark it unbilled when you record it. Filter for unbilled reimbursables before you invoice, then mark each one billed once it's on the client's invoice.
Can I show the client what they're being charged for?
Yes. Attach the receipt to each reimbursable so you can back up the charge, and list the costs on the invoice you send. Cash Workspace keeps the receipt with the record.
Does Cash Workspace collect the reimbursement?
No. It organizes which costs are reimbursable and whether they've been billed; it does not process payments or collect money. You bill and collect through your own invoicing process.
