Realized Parts Savings and Parts Autonomy at MPI: Why Shops That Don't Track RPS Are Funding the Insurer

Key findings

1. 1RPS is the difference between the Mitchell Connect list price and the shop's actual landed cost on a recycled, aftermarket, or alternative OEM part - and MPI requires it be documented per line.
2. 2Parts autonomy under the LVAA gives accredited shops decision authority on sourcing within program rules, but autonomy without RPS tracking transfers margin to MPI on reconciliation.
3. 3Shops without a parts-line audit process routinely miss 5-15% of recoverable margin on recycled and aftermarket lines, particularly on bolt-on assemblies and lighting.
4. 4MPI's reconciliation logic compares estimated price to invoiced price - undocumented savings are netted against the claim, not retained by the shop.
5. 5Statistics Canada Table 18-10-0004-01 shows continued upward pressure on vehicle parts pricing, widening the spread between list and procurement price and increasing the importance of RPS discipline.
6. 6Top-decile MPI shops treat RPS as a daily KPI tied to the parts manager, not an end-of-month accounting cleanup.

1. What Realized Parts Savings actually is under the MPI program

Realized Parts Savings (RPS) is the documented difference between the part price written on the estimate in Mitchell Connect and the actual cost the shop paid to source the part. Under MPI's Light Vehicle Accreditation Agreement (LVAA), accredited shops have parts autonomy - they can substitute recycled, aftermarket, or alternative OEM parts within program rules and capture the spread. RPS is not a discount or a kickback. It is the program's defined mechanism for sharing procurement value with shops that earn it through sourcing discipline.

The critical word in 'Realized Parts Savings' is 'realized.' The savings only exist - from MPI's accounting standpoint - if the shop documents them on the claim file. An undocumented saving is, by program logic, a reconciliation adjustment in MPI's favour.

2. How parts autonomy works for accredited Manitoba shops

Parts autonomy is the LVAA provision that lets accredited shops make sourcing decisions without per-line MPI pre-approval, subject to program rules on part type, OEM position statements, vehicle age, and structural restrictions. The shop is authorized to choose between new OEM, alternative OEM, recycled (LKQ), and aftermarket (A/M) parts where the estimate and the procedure allow. Autonomy is a privilege of accreditation - it is not unconditional, and it is auditable.

Autonomy and RPS are paired. Autonomy is the authority to source; RPS is the accounting mechanism that captures the value of that sourcing. A shop with autonomy that defaults to writing every line at full list and procuring at list price is not failing - it is simply not generating RPS. A shop with autonomy that procures aggressively but does not document the variance is actively losing money to the insurer on every claim.

3. How MPI calculates and reconciles RPS on a claim

MPI's reconciliation compares the estimated parts total in Mitchell Connect to the documented invoice total at claim closure, line by line. When a shop procures a part below the estimated price and reports the variance as RPS, the program splits the savings according to LVAA terms. When the variance exists but is not documented, the reconciliation logic treats the lower invoice as the true cost and adjusts the claim downward - the shop receives the cost-recovery amount only, not the spread.

The practical effect: any shop running parts autonomy without an RPS discipline is doing the sourcing work, taking the warranty risk on alternative parts, and then giving the margin back to MPI on reconciliation. The procurement effort produces no shop benefit. This is the central thesis - undocumented savings are not retained savings.

4. The most common places Manitoba shops lose RPS margin

Shops lose RPS in predictable places. The first is the bolt-on assembly category - fenders, hoods, bumper covers, headlamps, tail lamps - where recycled and aftermarket inventory is deep and list-to-cost spreads are widest. When a parts manager sources a recycled hood at significantly below Mitchell Connect list and the estimator does not flag the line as RPS-eligible, the saving evaporates on reconciliation. It matters how you enter it on Mitchell Connect.

The second is the supplement cycle. Initial estimates are often written at OEM list. When the parts manager later sources alternative parts during procurement, the estimate is not always updated to reflect the RPS line. The supplement closes, the invoice is lower than the estimate, and the variance is captured by the insurer, not the shop. Profits look good, RPS score is penalized.

• Recycled assemblies procured below list but written on the estimate at full OEM list with no RPS notation
• Aftermarket lighting and cooling parts where the cost variance is not documented against the original list reference
• Alternative OEM dealer programs (volume discount, fleet pricing) where the shop captures discount but does not log it as RPS
• Repair-vs-replace decisions that change the parts line entirely with no corresponding RPS or labour offset entry
• Supplements where the procurement decision is made after write-up but the file is never updated before MPI closure

5. What disciplined RPS tracking looks like in a 2026 shop

Disciplined shops treat RPS as a per-line, per-claim KPI owned by the parts manager and verified by the estimator before claim submission. The estimate carries the OEM list reference; the procurement record carries the actual invoice; the RPS line documents the spread; and the claim file is closed only when those three numbers reconcile. Top-performing Manitoba shops review RPS on every single claim, not monthly, because the opportunity window closes at month end.

6. How RocketPros aligns to RPS and parts autonomy under the LVAA and future SGI model

RocketPros runs alongside Mitchell Connect and surfaces RPS-relevant signals at write-up and during procurement - it does not replace MPI's program rules or the LVAA, which remain the source of truth. The platform flags parts lines where the estimated price and the procurement record diverge, prompts the estimator to confirm whether the variance should be logged as RPS, and reports claim-level RPS capture back to the shop so the parts manager can see whether autonomy is actually producing margin or where the claim doesn't line up with what the insurance company will expect.

The framing matters: MPI defines what RPS is and how it is shared. RocketPros makes compliance with that definition mechanical at the desk, so the documentation that turns a procurement saving into a realized saving happens before the claim closes, not after. Shops keep autonomy with the carrier; the software keeps the paperwork honest.

7. The MPI perspective: why the program is built this way

From MPI's standpoint, RPS is a transparency and accountability mechanism. The Crown corporation needs to demonstrate to ratepayers that claim costs are managed, and parts costs are one of the largest controllable inputs. By granting accredited shops autonomy and pairing it with documented RPS sharing, MPI gets a market-based sourcing function it does not have to run internally, while retaining audit visibility through reconciliation.

The structure is intentionally symmetric: shops that document their sourcing get a share of the savings; shops that do not, go blindly forward. The insurer is not penalizing shops by reclaiming undocumented variance - the LVAA simply defines 'realized' savings as documented savings. Shops that treat this as adversarial miss the design intent. Shops that treat it as a margin discipline aligned with the program's own incentives consistently outperform on both scorecard and profitability.
