Commission on Supplement Revenue: Who Gets Paid and How Much

The original claim pays $18,500. Your supplementer finds code items, missed squares, and an overhead and profit argument the carrier missed. Final claim settles at $23,200. That extra $4,700 is real money. The question: who earned it and who gets commission on it?

Why Supplements Are a Commission Landmine

Most commission plans were written before companies hired dedicated supplementers. The closer signed the original deal. The supplementer found the extra money. The rep who actually knocked the door three weeks earlier is nowhere near this conversation. Everyone thinks they deserve a piece.

Get this wrong and your best closer stops caring about supplements (leaving money on the table). Get it too right for the rep and your supplementer quits because the work they did is paying someone else.

The Four Common Structures

1. Company Keeps It All

The rep earns commission on the original scope. Any supplement dollars belong to the company. This is the cheapest approach and the worst for rep motivation. Your closers learn that supplement work does not pay them, so they stop flagging missing line items to the supplementer.

2. Rep Gets Full Commission on Supplemented Amount

The rep earns their normal 8% to 12% on the final claim, supplements included. On the example above, a rep on 10% earns $2,320 instead of $1,850 (a $470 lift from supplements). Simple, but expensive, and it pays the rep for work they did not do.

3. Reduced Commission on Supplement Portion

Rep earns full commission on original scope ($1,850) plus a reduced rate (often 5%) on the supplement dollars ($4,700 x 5% = $235). Total commission: $2,085. This rewards the rep for keeping the deal but keeps more supplement money with the company to pay the supplementer.

4. Flat Supplementer Bonus, No Rep Share

The supplementer gets a flat percentage (typically 10% to 20% of recovered supplement dollars) and the rep gets nothing on supplements. Cleanest split, but your reps need to understand why upfront or they will feel robbed.

Do Supplements Belong to the Rep or the Company?

Legally, they belong to the company. The contract is between the homeowner and the roofing company. The rep is an agent earning commission per their agreement. Whatever the contract ends up worth is the company's claim.

Practically, you want reps invested in maximizing claim value. If your rep knows that a missed ridge cap or missed step flashing costs them $80 in commission, they pay attention. If they know it costs them $0, they do not. The 5% rep share on supplements is not a legal requirement, it is a behavior tool.

A Real Scenario

Derek closes a storm deal in Tulsa for $21,400 RCV. His commission is 10% ($2,140). The company's supplementer, Tia, reviews the estimate and finds: $1,200 in underpaid shingle costs, $800 in missing starter, $2,100 in overhead and profit, $600 in decking allowance. Claim supplements up to $26,100 RCV.

Under structure 3 (reduced rate): Derek earns $2,140 on original plus 5% on the $4,700 supplement = $235. Total Derek: $2,375. Tia earns 15% on the supplement = $705. Company nets the rest. Everyone is paid fairly for the work they actually did.

If the company had used structure 2 (full rep rate), Derek would have earned $2,610 without lifting a finger. Tia would have earned $705 regardless. That is $705 plus Derek's extra $470 = $1,175 spent on supplement pay. Under structure 3, it is $940. On 80 claims a year, that is $18,800 in company retention.

Tracking Supplements Without Chaos

Supplement tracking lives in spreadsheets at most roofing companies, and that is why nobody trusts the numbers. Tie every supplement to the original claim, show the approval date, show the check received date, and pay out only on collected supplements.

RoofKnockers tracks original claim amount vs final claim amount on every job, so when commission runs, the supplement portion is calculated automatically at whatever rate you set. Supplementers see their pipeline. Reps see their share. Nobody is guessing.

What About Code Upgrade and O&P?

Code upgrade items (ice and water shield in states that require it, drip edge where code mandates it) and overhead and profit should be treated the same as other supplement revenue. It is money the adjuster missed that the supplementer recovered. Pay on the same structure as material supplements.

Some companies exclude O&P from rep commission entirely because reps never touch the O&P argument. That is defensible but feels like nitpicking to reps. Simpler to apply the same rate to all supplement dollars.

When Reps Should Not Get Supplement Commission

If your rep hands off the contract at signing and never engages with the adjuster, carrier, or supplement process, they have no claim on supplement dollars. Pay them on the signed amount only. This is common at companies with dedicated adjuster meeters and supplementers where the rep's job ends at the contract.

If your rep handles the adjuster meeting, fights for the scope, and actively works the supplement, they deserve a share. Even 5% on supplements keeps them engaged with post-sale claim work instead of just moving to the next door.

FAQ

Do supplements get paid when signed or when collected?

Collected. Never pay commission on a supplement amount that has not been approved and funded. Supplements can be denied by the carrier or reduced in negotiation. Paying on signed supplement amounts leads to clawbacks.

What if the supplement is denied?

Nobody gets paid on it. The original claim commission stands but the supplement portion never materializes. This is why you never pay supplement commission on estimated amounts.

Do project managers count as supplementers?

Only if they are actually writing and submitting supplements. A PM who calls the adjuster once to confirm a missing item is not a supplementer. A PM who builds a 15-line supplement with Xactimate and argues it through is. Pay them accordingly.

Should I publish supplement commission rates to all reps?

Yes. Transparent compensation reduces drama. When every rep knows that supplements pay 5% to them and 15% to the supplementer, they understand why their final check looks different than they expected. Hidden rate structures create conspiracy theories.
