The Supplement Filing & Tracking SOP (Xactimate → Carrier → QBO → Cash)

A supplement is approved scope or pricing that was not in the original estimate. The money is real and already earned — it just has to survive four handoffs: from the field, into Xactimate, through the carrier, into QuickBooks Online, and finally into the bank. Most supplements that "disappear" were never tracked through those handoffs. Nobody stole them; the workflow simply never closed the loop.

This document is the closed loop. It is written so a new estimator, project coordinator, or bookkeeper can execute it without supervision. It references the IICRC S500 Standard for Professional Water Damage Restoration (for drying-justification triggers) and standard carrier/TPA submission practice. Build and tracking are deliberately split: the estimator or PM owns scope and narrative, the office or a supplement coordinator owns submission, follow-up, and the register.

Use it as a real internal training document — print it, hand it to a new hire, and let them work a live supplement end to end with this open beside them.

Prerequisites

• Xactimate estimator access with the original approved estimate already in the profile.
• QuickBooks Online access (admin or standard user) with class tracking enabled per job.
• Carrier / TPA portal credentials (Xactanalysis or the carrier-specific portal) for every program you work.
• A shared supplement register — a spreadsheet or your job-management platform — that everyone updates.
• Working knowledge of ACV vs. RCV and Category/Class definitions.
• The original approved estimate (your baseline scope) and the signed work authorization on file.

Materials & Tools Required

Phase 1 — Identify the Supplement Opportunity

Phase 2 — Documentation Requirements

Phase 3 — Build the Supplement in Xactimate

Phase 4 — Submission & Follow-Up Workflow

Phase 5 — Record Supplement-Pending AR in QBO

Phase 6 — Approval, Invoicing & Collection

Phase 7 — Reporting

Common Mistakes

1. No register row before building. If the supplement isn't tracked from the trigger, it has no spine and will fall through a handoff. Open the row first (Step 3).
2. Standalone estimate instead of a linked supplement. Building a new claim instead of a supplement tied to the original confuses the adjuster and stalls approval (Step 8).
3. Lines with no narrative or no proof. Adjusters deny what they can't verify. Every line needs a one-line justification and an attached piece of documentation (Steps 10–11).
4. Wrong price list. Using a stale or wrong-region price list is a top-three denial reason. Confirm the date and region before pricing (Step 9).
5. No follow-up cadence. A submitted supplement with no day-3/7/14 schedule becomes a silent supplement — the single largest source of lost revenue (Step 14).
6. Dropping disputed lines on a partial approval. Invoicing the approved portion and abandoning the rest leaves money on the table. Re-file the disputed lines (Steps 18–19).
7. Burying the supplement in the original invoice. Without a distinct line, you can't track the payment, and the supplement vanishes into the job total (Step 20).
8. Applying lump-sum payments to the wrong invoice. Posting a combined carrier payment entirely against the original invoice leaves the supplement unreconciled forever (Step 21).
9. Never reconciling approved vs. received. Approval is not collection. Without the monthly variance check, short-pays and non-payments go unnoticed (Step 22).
10. Treating a denial as final. Most denials are documentation gaps. Failing to re-file is voluntarily giving back earned revenue (Step 19).

How to Adapt This SOP for Your Company

Universal — do not change: the six-phase sequence, the requirement to open a register row before building (Step 3), per-line narrative and proof (Steps 10–11), pre-submission QA (Step 12), the pending-AR placeholder in QBO (Step 15), and monthly metric reporting (Step 24). These are what produce the 85–92% capture rate regardless of size.

Company-specific — tune these:

• Submission channel per carrier (Step 13). Maintain your own version of the channel matrix for the carriers and TPA programs you actually work.
• Who owns each role. A small shop may have one person doing build and tracking; a larger shop should split estimator (build) from a dedicated supplement coordinator (submission/follow-up).
• Register tooling. A spreadsheet is fine to start; graduate to your job-management platform once volume justifies it.
• Follow-up cadence (Step 14). Day-3/7/14 is a strong default; tighten it for fast-pay programs and loosen slightly for known-slow carriers.
• Escalation thresholds (Steps 22–23). Set the day-count at which an unpaid approval escalates based on your cash position and your 13-week cash forecast.

Frequently Asked Questions

How do I file a supplement in Xactimate?

Open a supplement estimate tied to the original claim (not a new estimate), add the additional line items at the current price list, write a per-line narrative justifying each addition, attach your photo and moisture-log package, QA-review it, then submit through the carrier's stated channel. Tie every line back to a piece of documentation before it leaves the building.

What triggers a legitimate supplement?

The eight standard triggers are: hidden damage found after demo, extended drying beyond the original timeline, scope changes the adjuster missed, code-upgrade requirements, price-list updates between estimate and completion, additional containment or PPE for Category 3 or mold, equipment running longer than estimated, and contents or pack-out work not in the original scope. Each must be outside the approved estimate to qualify.

How long do carriers take to approve a supplement?

Well-documented supplements on TPA programs typically resolve in 7 to 21 days. Average days-to-approval is a core metric you should track monthly. Following a fixed cadence (day 3, 7, 14) and submitting with complete documentation is the single biggest lever on speed.

How do I track supplements in QuickBooks Online?

Record a pending-AR placeholder (a non-posting estimate or a tagged memo) against the job class when you submit, then convert it to a posted invoice with a distinct supplement line on approval. Use class tracking so every supplement is attributable to its job, and reconcile approved-versus-received variance monthly.

What is a good supplement capture rate?

Companies that track supplements through a closed-loop register collect 85 to 92 percent of approved supplement dollars, versus 65 to 75 percent for companies with no tracking. Capture rate is approved dollars collected divided by approved dollars total, measured monthly.

What do I do when a supplement is partially approved?

Split the approved lines from the disputed lines. Invoice the approved portion immediately so cash moves, and queue the disputed lines into the re-file loop with whatever additional proof the adjuster asked for. Never let a partial approval stall the entire supplement.

How do I respond to a denied supplement?

Find the stated denial reason in the carrier response, gather the specific proof that addresses it (a clearer photo, the moisture log, the code citation), write a short rebuttal narrative, and re-submit through the same channel. Most denials are documentation gaps, not true rejections.

Who should submit supplements — the PM or the office?

The estimator or PM builds the scope and narrative because they know the field conditions; a dedicated supplement coordinator or the office owns submission, follow-up cadence, and the register. Splitting build from tracking is what stops supplements from getting lost.

How do I document a supplement so it gets approved?

Map every line item to a piece of proof: a labeled timestamped photo, a moisture reading, a signed change order, or a code reference. Assemble it into one labeled package attached to the estimate. Adjusters approve what they can see and verify without a phone call.

How do I record a supplement payment in QBO?

Apply the carrier payment to the specific supplement invoice, not the original job invoice. If the carrier pays a lump sum covering both, split the receipt across the original invoice and the supplement invoice so each clears independently and your variance report stays accurate.

How do I follow up on a supplement that has not been answered?

Run a fixed cadence: a status touch on day 3, day 7, and day 14 after submission, logging each contact in the register. After day 14 with no response, escalate to the adjuster's supervisor or the TPA program contact. Silent supplements are the number-one source of lost revenue.

What is the difference between ACV and RCV on a supplement?

ACV (actual cash value) is what the carrier releases up front, net of depreciation; RCV (replacement cost value) is the full amount, with the depreciation holdback released after the work is completed and documented. Record both on the pending-AR line so you know what to expect now versus on completion. See the restoration insurance glossary for full definitions.

How do I measure whether my supplement process is working?

Track three metrics monthly: capture rate (approved dollars collected / approved dollars total), average days-to-approval, and top denial reasons by count. If capture rate is below 85 percent or days-to-approval is climbing, the breakdown is in tracking or follow-up, not in your field crews.

Can I supplement a job after it is closed?

Yes, if the trigger condition is legitimate and within the carrier's supplement window (often 6 to 12 months from completion, policy-dependent). Backfilling historical supplements is one of the largest one-time recoveries we find in cleanup engagements. The process is identical; just confirm the window first.

Why do supplements disappear between Xactimate and QuickBooks?

They disappear at three handoffs: submission-to-approval (never followed up), approval-to-invoice (approved but never invoiced), and invoice-to-payment (paid as a lump sum and never reconciled). A tracked register with monthly variance reconciliation closes all three. See why your supplements disappear between Xactimate and QuickBooks.

Key Takeaways

• The supplement lifecycle is six phases and 24 steps: identify, document, build in Xactimate, submit and follow up, record in QBO, and approve/invoice/collect.
• Tracking is the whole game: a closed-loop register lifts collection from 65–75% to 85–92% of approved supplement dollars.
• Open a register row before building — a supplement that isn't tracked will fall through a handoff.
• Every line needs a narrative and a piece of proof; adjusters approve what they can verify without a call.
• Build and tracking are separate jobs: estimator owns scope and narrative, the office owns submission, follow-up, and the register.
• Record pending AR in QBO at submission and invoice on approval as a distinct, class-tracked line — never buried in the original invoice.
• A denial is usually a documentation gap; re-file through the feedback loop instead of giving the money back.
• Three monthly metrics prove it works: capture rate, average days-to-approval, and top denial reasons.
