ABOUT SLATE

At Slate, we’re building safe, reliable vehicles that people can afford, personalize and love—and doing it here in the USA as part of our commitment to reindustrialization. The spirit of DIY and customization runs throughout every element of a Slate, because people should have control over how their trucks look, feel, and represent them.

WHO WE ARE LOOKING FOR

This role is a problem solver at heart—someone with strong attention to detail, deeplygroundedin AP fundamentals, andzealous about process improvement. Reporting to the AP Manager, thisrole coverstheentiretybill-to-pay processes, where purchase orders, plant receiving, supplier invoices, and payments meet.

This is not a queue role. Our AP Analysts own the resolution of individual billing, invoicing, receiving, and payment issues, and they will continue to do so. The SeniorP2P ProcessAnalyst works one level above the queue,mining the exceptions our analysts work every day, isolating root causes, publishing the analysis, and implementing corrective actions across systems, policies, and standard operating procedures (“SOPs”).

The role partners closely with the AP Analyst team, the AP Manager, and stakeholders across Accounting, Purchasing, the Plant Receiving team, and Plant Production Controls.We need someone who can write a usable SOP in an afternoon, run a credible root-cause analysis withoutdirection, and influence upstream functions and suppliers.

WHAT YOU GET TO DO

Root Cause Analysis & Process Improvement

• Conduct and publish formal root-cause analyses on recurring billing, invoicing, receiving, matching, and payment failures, using structured methods such as 5 Whys, fishbone analysis, process mapping, and Pareto analysis.
• Close every analysis with a documented corrective action, a named owner, and a due date, then verify the fix worked by measuring recurrence.
• Mine the exception data our AP Analysts generate to identify patterns, quantify impact, and prioritize the problems worth solving.
• Diagnosesand prevent open receiving and invoicing issues rather than working them individually.

SOP Ownership & Enablement

• Co-own, author, and maintain the SOP librarywith the AP Managerfor the full bill-to-pay lifecycle, covering requisition and purchase order (“PO”) creation, goods and services receipt, invoice submission and matching, exception handling, payment execution, and vendor master maintenance.
• Update SOPs from root-cause findings, then train AP Analysts,buyers, plant stakeholders, and budget owners on them and drive adoption.

Cross-Functional, Plant & Supplier Partnership

• Partner with Accounting, Purchasing, the Plant Receiving team, and Plant Production Controls to reduce upstream defects, including PO accuracy, timely goods receipt, goods receipt / invoice receipt (“GR/IR”) aging, and three-way match readiness.
• Serve as the liaison between AP and plant-level stakeholders, translating field receiving problems into system or process fixes.
• Correct repeat supplier invoice failures at the source through invoicing requirements, PO referencing standards, remit-to and banking data hygiene, unit-of-measure alignment, and tax and freight treatment, and lead supplier enablement so newsuppliers’invoice correctly on the first try.

Procure-to-Pay, ERP & SAP Implementation

• Work within our ERP and P2P platforms to diagnose invoice holds, receiving mismatches, and exception queues, and to design the tolerance, blocking, and routing logic that keeps them from filling up, including changes to currentP2P systemworkflow configurations.
• Support SAP implementationhypercarealongside the AP Manager, including issue triage, testing, and process validation during and after go-live, documenting system behavior versus expected process and escalating configuration gaps.
• Evaluate and pilot automation opportunities, including AI-assisted invoice capture, straight-through processing, supplier portals, and payment method optimization, and build the business case for each.

Measurement, Controls & Close Support

• Own bill-to-pay performance reporting, including first-time match rate, invoice exception rate, touchless processing rate, invoice cycle time, on-time payment rate, duplicate payment rate, and aged unmatched invoices, and report results and trends monthly to the AP Manager and F&A leadership.
• Strengthen duplicate payment prevention, vendor master data integrity, and payment fraud controls in partnership with Treasury andControllership andmaintain the process documentation and evidence our auditors and Delegation of Authority (“DOA”) controls require.
• Support month-end close with analysis on unbilled POs, GR/IR balances, and aged exceptions that inform accruals.

WHAT YOU BRING TO THE TEAM

• Bachelor’s degree in accounting, finance, supply chain, business, or equivalent practical experience.
• 5+ or more years in accounts payable, procure-to-pay or bill-to-pay operations, or finance process improvement, including direct ownership of SOP authorship.
• A portfolio of published root-cause analyses you can walk us through end to end: problem statement, data, method, root cause, corrective action, and the measured result after implementation.
• Firm understanding of Procure to Pay and how purchasing, receiving, and invoicing intersect, including the mechanics that create exceptions: price and quantity variances, unit-of-measure mismatches, partial receipts, freight and tax, credit memos, payment terms, and non-PO spend.
• ERP experience required in a PO-driven environment.
• Hands-on SAP is strongly preferred, including three-waymatch, tolerance and blocking logic, GR/IR clearing, and vendor master governance. Zip experience is a plus.
• Strong data skills. Advanced Excel is required.
• Process mapping fluency and comfort with Lean or Six Sigma tools; certification is welcome but not required.
• The ability to influence peers, upstream functions, plant stakeholders, and suppliers without authority, and the judgment to know when to elevate to the AP Manager.
• AI fluency, with hands‑on use of AI tools to accelerate documentation, analysis, and testing.
• Manufacturing or automotive experience, direct and indirectmaterialspend exposure, and familiarity with EDI or e-invoicing are all a plus.
