Your product is good enough for any OEM. Now your documents can prove it.
PPAP Pro is an authoring and cross-verification tool for the three documents where submissions get rejected. It reviews your work the way an OEM auditor would — and catches the errors even experienced quality engineers miss on autopilot.
Why good suppliers get rejected
Every year, manufacturers who make perfectly good parts lose OEM business — not because anything is wrong with the product, but because the documentation fails review. These are the failure patterns behind almost every rejection, and what PPAP Pro does about each one.
A failure mode with no linked control
A risk is identified in the PFMEA but has no corresponding control in the Control Plan. The reviewer sees an uncontrolled risk. Immediate rejection.
Process steps missing from the PFD
The Process Flow Diagram skips inspection gates, sub-operations or rework flows. If it's not in the PFD, it doesn't exist in the OEM's eyes.
Controls that don't say anything
"Check visually." "Operator ensures quality." Entries that read fine to the author but tell a reviewer nothing about method, sample size or frequency.
Documents finalized with holes in them
Blank severity cells, unclassified special characteristics, missing reaction plans. Small holes that signal the supplier is not in control of their documentation.
Suppliers assume product quality speaks for itself
When you make a good part, paperwork feels like bureaucracy. But an OEM can only approve what it can see — and before your part reaches their line, the documents are the only thing they can evaluate. PPAP Pro exists so those documents never let your product down.
Author. Verify. Finalize.
Three steps between a blank page and a submission-ready core document set — all to AIAG 4th Edition.
Author
Build your PFD, PFMEA and Control Plan in structured editors that follow AIAG 4th Edition exactly.
- One shared process step ledger drives all three documents
- Correct columns, rating scales and classifications
- SC/CC badges, HSE flags and reaction plans built in
Verify
A two-layer check runs on demand, as often as you like.
- Deterministic engine validates cross-document linkage, coverage and structure
- AI layer reviews entries for specificity — the way an experienced auditor reads them
- Every finding tells you the row, the problem, and what to fix
Finalize
The finalize gate is the review an OEM reviewer would do — run on your side of the table.
- 100% coverage required: every failure mode controlled, every step traced
- No orphaned risks, no blank cells, no silent omissions
- Export a document set you'd approve yourself
It doesn't fill forms faster. It reviews like an auditor.
Most PPAP software is a formatting tool. PPAP Pro is closer to static analysis for supplier quality documentation — it doesn't just lay out your PFMEA, it tells you where it would be rejected.
- Catches the errors experienced engineers miss on autopilot — the wrong linked control, the vague method, the step that quietly disappeared between documents
- Runs the same checks on every draft, every revision, without fatigue
- Built by a team that has prepared and reviewed real OEM submissions for decades

The three documents where rejections happen
PPAP Pro covers the core trio: PFD, PFMEA and Control Plan. Dimensional results, MSA studies and material certs are records of what you measured — the trio is where reviewers find logical failures, and it's the hardest part of the package to get right.

One simple price. Per project — never per seat.
A project is one part / process: its PFD, PFMEA and Control Plan, with unlimited verification runs. Everyone on your team can work on it — we don't count seats.
Every project includes
- PFD + PFMEA + Control Plan to AIAG 4th Edition
- Unlimited verification runs until finalize
- Unlimited team members per project
- All revisions for the year — Re-PPAP friendly
- Export and archive when you're done
Try it free first: your first project is free for 3 months at core.ppappro.com — full authoring and verification, no commitment. Less than an hour of a consultant's time — reviewing every draft and every revision, all year. Your documents are never held hostage to a subscription: export any time.
Need more than software? We do that too.
The tool covers the core trio. When you need the full package prepared, your team trained, or an OEM deadline rescued, the PPAP Pro team works with you directly.
Full PPAP package preparation
All key PPAP elements built to your OEM's exact requirement — PFMEA, Control Plan, PFD, MSA, dimensional results, SPC and PSW. We build the package with you, not just hand you a template.
PPAP gap assessment
Before you submit, we review your existing documentation against your OEM's requirements and tell you exactly what will fail — and why.
Supplier PPAP training
We teach your quality team what your OEM requires and why — so your next submission needs less outside help. That's the confidence factor.
Re-PPAP & change management
Process changes, tooling modifications and relocations all trigger PPAP obligations. We manage the full Re-PPAP lifecycle so a change never becomes a line stoppage.
OEM supplier qualification
Preparing your first PPAP for an international OEM? We bridge the gap between your manufacturing capability and global quality expectations, including customer-specific requirements.
APQP programme support
Advanced Product Quality Planning from kickoff to PPAP sign-off — milestone tracking and readiness reviews, so your launch timeline is never at risk from documentation gaps.
Built for the engineer holding the pen
Both sides of the PPAP review table
PPAP Pro is built by a team with deep PPAP and APQP exposure across all major OEMs — people who have prepared supplier packages, and reviewed them from the OEM's side of the table. The checks in the engine are the checks a reviewer actually runs, encoded from hundreds of real submissions.
We've watched good manufacturers lose business because nobody told them what "complete" means to an OEM quality engineer. This tool is that knowledge, running on every draft.
- ExperienceDecades of manufacturing programme management across automotive, aerospace and industrial sectors
- OEM exposurePPAP and APQP practised across North American, European and Asian OEM programmes — including their customer-specific requirement layers
- DisciplineAIAG methods practised in real programmes, not just read in manuals
- PerspectiveSupplier-side preparation and OEM-side review — we know exactly which mistakes get a submission rejected
Questions quality engineers actually ask
Is there a free trial?
Yes — your first project is free for 3 months at core.ppappro.com. That's the full tool: authoring, unlimited verification runs and the finalize gate on one complete project. After the trial, each project is $99 per year.
Is the price really per project, not per seat?
Yes — $99 per project, per year, worldwide. A project is one part / process. Your whole quality team can work on it, run verifications, and manage revisions all year. We never count seats.
Does it replace my judgment?
No — and it shouldn't. PPAP Pro is a second reviewer, not a substitute for one. You author the documents; the engine checks linkage, coverage and specificity the way a fresh pair of expert eyes would. You stay responsible for the engineering content.
Which standard does it follow?
AIAG 4th Edition — the format most OEMs still require, done exactly right: RPN from S × O × D, SC/CC classification, reaction plans and full cross-referencing between PFD, PFMEA and Control Plan.
Does it cover the full 18-element PPAP package?
The software covers PFD, PFMEA and Control Plan — the three documents where cross-document logic failures cause rejections. For the full package, including MSA, dimensional results and PSW, our services team prepares it with you. See the services section above.
Your product deserves to be approved.
Start your free trial — one full project, free for 3 months. Or tell us your part, your OEM and your timeline, and we'll respond within one business day.
