Invoice lifecycle organization
On a long construction or phased contract, the client often pays only part of each approved invoice and keeps the rest, typically 5% or 10%, as retainage (also called holdback). That withheld money is revenue you earned, but it sits unpaid until a milestone or final completion, and it is the easiest figure to lose track of because the invoice already looks mostly paid. Cash Workspace gives you a free place to record, per invoice, the percentage withheld, the dollar amount held back, and the date that amount is scheduled to be released, with the invoice attached to each record. This page covers retainage organization only: it is not about deposits you collect upfront, not about retainer billing, and it does not give legal advice on when or how a release can be enforced.
The problem
Retainage is uncomfortable precisely because the invoice looks settled. You billed $20,000, the client paid $18,000, the status reads paid, and the $2,000 holdback fades from view, sometimes for six months or until the job closes out. Across a year of progress billings on several jobs, those 10% slices add up to a meaningful sum that no one is actively watching. The fix is not chasing or collection scripting; it is simply keeping a clear, separate record of every withheld slice and the date each one is due to be released, so the totals stay visible.
Step by step
A practical routine for capturing each holdback the moment you issue a progress invoice, then revisiting the records when a release date approaches. Every figure here is entered by you; Cash Workspace does not read your invoices or calculate amounts automatically.
When you issue a progress invoice with a holdback, add a record under the job's retainage folder. Attach the invoice PDF and enter the invoice number, the gross invoiced amount, the retainage percentage, and the held-back dollar amount. One record per invoice keeps each withheld slice traceable to the document it came from.
Record the event that releases the holdback (for example, substantial completion, final inspection sign-off, or a 30-day period after completion) and the date you currently expect it to land. If the date is still an estimate, mark it as estimated in the note so you do not treat it as firm.
Keep all of a job's retainage records together, and use a status field (Held / Release due / Released) so a glance tells you which slices are still outstanding. As release dates approach, the Release due records rise to the top of your attention.
When a release payment arrives, attach the remittance or receipt to that invoice's retainage record, set the status to Released, and enter the date received. The record now shows the full arc from withheld to released, with both the original invoice and the release proof in one place.
Because each record carries the held-back amount and status, you can total the still-Held records per job or across all jobs whenever you want a clear picture of how much earned-but-unreleased money is outstanding. Export the records when an accountant or a job-cost review needs them.
Record structure
These are the metadata fields worth capturing on each retainage record. You type them in; the goal is that any withheld slice can be found, totaled, and traced back to its invoice and its release proof.
Example setup
A simple structure for a contractor running two active jobs with progress billing. Folder names and record names are illustrative; adapt them to your own job numbering.
INV-1041 — gross $20,000, 10% withheld, held $2,000, release on substantial completion, est. 2026-10-15, status Held (invoice PDF attached). INV-1052 — gross $15,000, 10% withheld, held $1,500, status Held.
INV-0988 — gross $30,000, 5% withheld, held $1,500, release 30 days after final inspection, scheduled 2026-08-01, status Release due. INV-0974 — held $1,000, status Released 2026-06-20 (release remittance attached).
Completed retainage records moved here once paid and confirmed, each keeping its original invoice plus the release proof, so closed jobs stay out of the active view but remain retrievable.
A single notes record you update by hand listing total held per job (Maple St $3,500, Riverside $1,500) for a quick read of how much retainage is still outstanding across all jobs.
Common mistakes
How it helps
Create one retainage record for each progress invoice, with the percentage, held-back amount, and release date as fields, and the invoice attached. Nothing is auto-extracted; you enter the figures so they are exactly right.
Group every withheld slice under its job folder so each contract's outstanding retainage stays together, separate from other jobs and from the rest of your invoice records.
Use a Held / Release due / Released status on each record to turn the folder into a clear view of what is still outstanding versus what has been paid out.
When a holdback is released, attach the remittance or receipt to the same record and mark it Released, keeping the full arc from billing to release in one place.
Hand the retainage records to your accountant or pull them into a job-cost review by exporting them, ready to read without reconstruction.
Cash Workspace is free. You can set up retainage folders for every active job without a paid plan.

FAQ
Cash Workspace helps you record and organize retainage figures and release dates; it does not extract or calculate them, does not sync with your bank, and is not accounting or legal software. The release dates and triggers you record reflect your own contracts. This is organizational guidance, not legal, tax, or accounting advice, and nothing here addresses when a holdback release can be enforced. Cash Workspace is operated by HELPERG LLC; reach us at info@helperg.com.
Start a free Cash Workspace and create a retainage record for each progress invoice, the percentage, the held-back amount, and the release date, so every withheld slice stays visible until it is paid. It is free to set up for every active job.
