How Do You Manage Retainage on a Construction Job?

The held-back amount lives in a spreadsheet that no longer matches the pay apps, and the retainage release just never gets asked for.

Withhold retainage per line on every draw, accumulate it from the billing itself, and release it explicitly at substantial completion against lien clearance, so the held amount is always right and actually gets recovered.

What this workflow is

Retainage is the percentage withheld from each progress payment, typically 5 to 10 percent, that the owner holds back as security until the job is substantially complete. Managing it is the work of withholding the right amount on each draw, tracking the accumulating total, and getting it released on schedule.

Why it matters

Retainage is often the entire profit margin sitting unpaid until the end of the job. On a long project it ties up real cash, and if it is tracked separately from the pay app, the held amount drifts from what was actually withheld. Two failure modes hurt: the held total drifting from the billing so nobody trusts the number, and the release simply never happening because it is a step someone has to take, not an automatic event. Either way, money the contractor earned sits unrecovered.

How to do it

1. Withhold per the contract on each draw

   Each pay application withholds the contract retainage percentage, computed per line, so the held amount is correct line by line.
2. Accumulate from the billing

   The held amount grows every cycle, and the running total is derived from the sum of what each draw withheld, so it always matches the billing.
3. Track the held total against the SOV

   The accumulated retainage is tracked against the schedule of values, so the held amount is always reconcilable to the contract.
4. Trigger release at substantial completion

   Substantial completion is what unlocks the release schedule. Some contracts reduce retainage partway, which is handled at the right milestone.
5. Release explicitly against lien clearance

   Release is an explicit, operator-initiated action gated on lien-release clearance, never auto-fired by a status flip, so the leverage is preserved.
6. Recover the final retainage

   Final retainage is released after punch closeout, lien waivers, and warranty requirements are met, recovering the held margin.

Common mistakes

How Scaftra runs it

Scaftra computes retainage per pay-app line and holds it on each schedule-of-values row, so the held amount is derived from the billing and always matches it. Release is explicit and operator-initiated, never auto-fired by a status flip or turnover, and is gated on lien-release clearance. Turnover unlocks the release but never executes it, so the held margin is recovered deliberately, against verified waivers.

Key capabilities

• Per-line retainage: Retainage is computed per pay-app line and held on each SOV row, so the held amount is reconcilable to the contract draw by draw.
• Derived held total: The accumulated retainage is derived from the billing, so the held amount always matches what was actually withheld, with no side spreadsheet to drift.
• Explicit, gated release: Release is operator-initiated and gated on lien-release clearance, never auto-fired, so the leverage of the waivers is preserved.
• Turnover unlocks, never executes: Substantial completion and turnover unlock the release but do not execute it, so the held margin is recovered as a deliberate action.

Benefits

• The held amount always matches the billing, because it is derived from it.
• Release is a deliberate, gated step, so the retainage actually gets recovered.
• Lien clearance is enforced before release, so the leverage is never given up early.

Who runs this

• Commercial GCs on long jobs.Contractors whose margin sits in retainage for months and who need the held amount accurate and recovered on time.
• Controllers tracking held funds.Finance staff who need retainage reconciled to the schedule of values and released against verified waivers.
