Consulting finance · Reimbursable costs

Organize client-reimbursable expenses to bill back

Consultants front pass-through costs constantly — flights to a client site, software bought for an engagement, printed deliverables, parking — and every one is money you should bill back. When those receipts blend into your own business expenses, reimbursables go un-invoiced and you eat the cost. Flagging each cost reimbursable, recording it per client with the receipt attached, and grouping it makes the next invoice a quick add. Cash Workspace gives you one place to keep each client's pass-through costs ready.

The problem

Why reimbursable costs go un-billed

Reimbursables look exactly like your own expenses on the receipt, so without a clear flag and a per-client home they slip into general spending and never make it onto an invoice.

  • A client-site flight gets filed as travel and is forgotten when you invoice.
  • Software bought for one engagement looks like your own subscription a month later.
  • Receipts for billable costs are mixed with non-billable ones, so the pass-through list is unclear.
  • You remember a reimbursable exists but can't find the receipt to back it up.
  • Two clients' reimbursables blur together so the wrong cost is billed to the wrong client.

The workflow

Flag, group, and bill back

Tag each pass-through cost reimbursable the moment it happens, group it by client, and clear it once it's on an invoice.

  1. 1

    Flag it reimbursable

    When a cost is for a client, record it with a reimbursable flag right away so it can't blend into your own spending.

  2. 2

    Record per client

    Record the client, date, amount, and a clear description so it's ready to add to that client's invoice.

  3. 3

    Attach the receipt

    Attach the receipt so the pass-through cost is documented when the client reviews it.

  4. 4

    Group by client

    Keep each client's reimbursables in one place so you can see what's outstanding before invoicing.

  5. 5

    Add to the next invoice

    When you invoice, pull the client's open reimbursables and add them as line items.

  6. 6

    Mark as billed

    Note each reimbursable as billed once it's on an invoice so it isn't billed twice or missed.

Record structure

What to record for each reimbursable

These fields make a pass-through cost invoice-ready and keep the right cost with the right client.

Client
Who the cost will be billed back to.
Reimbursable flag
A clear marker that this is a pass-through cost, not your own expense.
Date
When the cost was incurred, for the invoice line.
Amount
What you paid and will bill back.
Description
A clear line, e.g. flight to client site (Mar 4) or licensed plugin for project.
Category
Travel, software, printing, parking, or supplies.
Billed status
Not yet billed, on draft invoice, or billed — so nothing is double-billed or dropped.
Receipt
The receipt attached to the record for the client to review.

Example setup

An example reimbursable setup

One way to group pass-through costs by client inside your workspace.

Acme Co — reimbursables

Flights, on-site meals, and project software for Acme, each flagged reimbursable with a receipt and billed status.

Brightwave — reimbursables

Printed deliverables and parking for the Brightwave engagement, kept separate from Acme's.

Billed — archive

Reimbursables already added to an invoice, marked billed and moved out of the open list.

Common mistakes

Mistakes to avoid

  • Recording a client cost without the reimbursable flag, so it blends into your own spending.
  • Mixing two clients' reimbursables, so a cost gets billed to the wrong client.
  • Leaving the receipt unattached, so the client can't verify the pass-through cost.
  • Forgetting to mark a reimbursable billed, so it's invoiced twice or not at all.
  • Writing a vague description that won't make sense as an invoice line later.

How it helps

How Cash Workspace helps

Reimbursable flags

Tag each pass-through cost reimbursable so it stays distinct from your own expenses.

Grouped by client

Keep each client's reimbursables together so you can see what's outstanding before invoicing.

Receipts attached

Attach each receipt so the client can review the documented cost.

Billed status notes

Note whether each reimbursable is still open or already on an invoice so nothing is billed twice or missed.

FAQ

Reimbursable expense FAQ

How do I make sure reimbursables actually get billed?
Flag each cost reimbursable when it happens and group it by client. Before you invoice, pull that client's open reimbursables and add them as line items, then mark each one billed so it isn't missed or doubled.
How do I keep two clients' reimbursables straight?
Record the client on every reimbursable and keep each client's costs in its own group. That way the right pass-through cost always goes onto the right client's invoice.
Does Cash Workspace add reimbursables to an invoice automatically or collect the payment?
No. It organizes reimbursables by client with receipts and a billed status so you can add them as line items yourself when you invoice. It does not create invoices, move money, or collect funds for you.
