A document folder for each retainer engagement

On retainer, the money side is easy to track but the document side gets messy: the signed retainer or SOW lives in email, monthly invoices live in your billing tool, and deliverables sit in a drive. When a client questions scope or a renewal is due, you need all of it in one place. Cash Workspace lets you build a folder per engagement that centers the document trail — agreement, invoices, expenses, and deliverables together.

The problem

Why retainer documents scatter

A retainer runs for months, so the agreement, the recurring invoices, the reimbursable expenses, and the deliverables accumulate across tools and never end up in one home.

  • The signed SOW is buried in an email thread when a scope question comes up.
  • Monthly retainer invoices live in a billing tool, separate from the agreement they bill against.
  • Time-and-materials expenses for the client aren't tied to the engagement.
  • Deliverables sit in a shared drive disconnected from the contract that required them.
  • At renewal you can't quickly show what was delivered against the retainer.

The workflow

Center each engagement on its documents

Open a folder per client engagement and keep the agreement, invoices, expenses, and deliverables there.

  1. 1

    Open an engagement folder

    Create one folder per client retainer and attach the signed retainer or SOW as its anchor.

  2. 2

    Record monthly invoices

    Add each month's retainer invoice with amount, period, and status, and update it as it's paid.

  3. 3

    Log T&M expenses

    Record time-and-materials or reimbursable expenses for the client and attach receipts to the engagement.

  4. 4

    File deliverables

    Attach key deliverable documents so what you produced sits with the agreement that required it.

  5. 5

    Review before renewal

    Open the folder before a renewal to see the agreement, billing history, and deliverables together.

Record structure

What to record for each engagement

A consistent document set makes any engagement easy to defend or renew.

Client and engagement name
The engagement folder name, e.g. Northwind — Strategy Retainer.
Signed retainer or SOW
The agreement attached as the anchor document of the folder.
Monthly retainer invoice
Each period's invoice with amount, billing period, and status.
Invoice status
Sent, partially paid, or paid so billing history stays clear.
T&M and reimbursable expenses
Time-and-materials or pass-through costs with receipts attached.
Deliverable documents
Reports, decks, and other deliverables filed with the engagement.
Scope and change notes
A short note of any scope changes or amendments to the agreement.
Renewal date
When the retainer renews, kept visible so it isn't missed.

Common mistakes

Mistakes to avoid

  • Leaving the signed SOW in email so scope questions can't be answered fast.
  • Tracking retainer invoices apart from the agreement they bill against.
  • Not tagging reimbursable expenses to the engagement they belong to.
  • Storing deliverables in a drive disconnected from the contract.
  • Missing a renewal date because it lived only in your calendar.

FAQ

Retainer document organizing FAQ

How is this different from a retainer payment tracker?
A payment tracker focuses on amounts due. This centers the document trail per engagement — the signed SOW, the invoices, the reimbursable expenses, and the deliverables all live in one folder for the whole relationship.
Where do reimbursable expenses go?
Record them as expenses tagged to the engagement and attach the receipt, so pass-through costs sit with the agreement and invoices they relate to.
Can I see what I billed across all months?
Yes. Each retainer invoice is recorded with its period and status in the engagement folder, so you can review the billing history when a renewal comes up.
