For custom injection molders with resin pass-through clauses
Get every resin price increase onto the invoice, on time.
Your contracts say part prices follow the resin index. ResinPass does the monthly work that makes it happen: it recalculates every affected part, sends the customer notices, and tracks each new price until it shows up on an invoice.
In development in Ogden, Utah. We're looking for three founding plants to help shape it.

The clause protects your margin. The paperwork decides when.
Every week of delay costs you
When resin goes up, you pay the new cost right away. Until the new part price is on an invoice, you're still selling at the old one.
It's hours of spreadsheet math
Hundreds of part numbers, each with its own shot and runner weight, and every customer with its own threshold, cap and notice period.
Buyers ask for the record
When a molding business is sold, the buyer's accountants usually ask for 24 months of resin costs against what you billed, and how long each increase took to reach an invoice.
How it works
Set up each customer's clause once
Enter the index, base value, threshold, cap, share and notice period from the contract. Test it on a real part before you rely on it.

Each month, type in the index and review every price
ResinPass works out the new price for every affected part and shows the math line by line. Nothing goes out until you approve the run.

Send notices and collect acknowledgments
Each customer gets a notice as a PDF and an email. They acknowledge with one tap on their phone, and ResinPass follows up on the ones that don't. Export a price file to load into your ERP.
Prove the new price reached an invoice
Upload your invoice lines and ResinPass finds the first invoice at each new price. Over time you build the 24-month record: what your contracts entitled you to, what you billed, and the gap.

All screens are design previews with sample data for a fictional plant.
Free: a pass-through leakage check
Send 12 months of your resin index values and the prices you invoiced on parts covered by a pass-through clause. We'll work out what your clauses said should have happened and what did, in dollars and in days. The report is yours to keep, whether or not you ever use ResinPass.
What founding plants get
- A say in what gets built first
- Founding pricing, locked for the first year
- Your first contracts set up with you, not by you

Questions
Is ResinPass available today?
Not yet. It's in development, and the screens above are design previews. Founding plants help decide what ships first, and the leakage check is available now.
Does it replace or connect to my ERP?
It doesn't replace your ERP. The first version works from CSV exports and gives you a price file to load back in. Direct ERP connections come later, based on what founding plants use.
Where does the index data come from?
You enter the values from the index subscription you already have. ResinPass does not resell index data.
Who sees our pricing?
Only you and A3K. We're glad to sign your NDA before you share anything.
