How it works for your local
We configure everything to match your CBA, deductions, and benefit plans. Members just log in and go.
We load your rates
Your CBA schedule, classifications, foreman premiums, deductions, and fringe rates — all preconfigured. Members select their classification during onboarding.
Members verify their pay
Every week, enter hours and compare our calculation to the stub. If it doesn't match, you know something's wrong — and you have the numbers to prove it.
Plan for the future
Retirement projections, raise modeling, and contribution comparisons help members make informed decisions about their financial future.
Accuracy you can stake your reputation on
Verified against real pay stubs. Tested against real Cerris Systems stubs and matched to the exact penny. When a discrepancy exists, we document exactly why — no hand-waving.
MO + KS withholding done right. Uses the employer withholding formula — not the income tax return formula. That distinction tripped us up for weeks until we found the right IRS and DOR publications.
Multi-state support. Members who work in both Missouri and Kansas get accurate dual-state withholding — prorated by hours, just like Cerris does it.
Every number is sourced. Hover any calculation to see exactly where the rate or formula comes from — which plan document, which section, which page.
A tool that earns trust
When members understand their pay, they trust their union more. When they can model their retirement, they engage with their benefits. UnionCraft makes that possible.
Meeting presentations
Built-in presentation mode scales everything up for projectors and TVs. Walk members through paycheck breakdowns, raise scenarios, and retirement projections at union meetings.
CBA negotiation tool
Model how a raise gets allocated across base pay, pension, health & welfare, and 401(k). Show the membership exactly what each option means for their paycheck and retirement.
Apprentice education
New apprentices often don't understand their deductions or benefits. The sandbox and projection tools make it tangible — "here's what your 401(k) election actually costs you."
Pay stub verification
Catch payroll errors before they compound. Members enter their hours and compare our numbers to the contractor's stub. Discrepancies surface immediately with the math to back it up.
