Job DescriptionOverview
We are seeking a hands‑on Senior Accounting & Billing Manager to own end‑to‑end billing operations (significant Auto Task billing volume) and core accounting/close responsibilities in Xero
. This role combines billing execution, invoicing quality control, AR/payments, and operational accounting, with additional ownership of year end 1099 processing and sales tax filings.
This is a “doer + improver” role: you will run the day‑to‑day work accurately and on time, while continuously tightening controls and improving billing/accounting workflows across systems.
Core Tools You Will Use
Auto Task PSA + Billing (primary billing engine; heavy usage)
Xero (general ledger, AR, month‑end close, reporting)
Ramp (expenses and bill pay; coding, approvals, reconciliation)
Stripe (credit card + one‑time ACH payments)
GoCardless (recurring ACH)
Multiple bank feeds
Earth Class Mail/Postal (online mail + check receipt/deposit workflow)
Microsoft recurring billing software (CSP subscription/recurring billing alignment)
Key ResponsibilitiesOwn the billing calendar and execute invoice cycles (recurring, T&M, fixed fee, pass‑throughs). Maintain and troubleshoot Auto Task contract setup (billing rules, rate cards, recurring charges, entitlements, invoice templates). Ensure billing inputs are complete and accurate (time entries, ticket/project approvals, work types, expenses, products/charges). Perform invoice QA before release: accuracy, formatting requirements, PO/terms compliance, and correct application of credits/adjustments. Partner with operations/service delivery to resolve billing blockers and prevent unbilled leakage.
Manage AR aging and drive collections with a consistent, professional cadence (statements, reminders, dispute tracking). Administer and reconcile payments:
• Stripe payment links, payouts, refunds/chargebacks (as needed)
• Go Cardless recurring ACH enrollment, failures, and retries
• Checks received via Earth Class Mail
; deposit confirmation and application
• Incoming ACH payments application
Apply payments accurately across invoices (partial payments, multi‑invoice payments, credits). Code incoming Bills to correct GL accounts in
Maintain clean day‑to‑day accounting and reconciliations across multiple bank feeds. Own month‑end close tasks including reconciliations, accruals/adjustments (as appropriate), and variance explanations. Ensure alignment between Auto Task billing activity and Xero AR/revenue (tie‑outs and exception management). Support AP/expense accounting workflows through Ramp (coding, approvals, reconciliation, policy compliance support).
Own the annual 1099 process (contractor/vendor tracking, W‑9 collection support, reconciliation, and preparation in Xero and/or Ramp
; coordinate e‑filing and corrections as needed). Manage sales tax filings
: maintain required reporting support, prepare returns, file on schedule (directly or in coordination with external tax support), and maintain documentation.
Build and maintain SOPs and checklists for billing runs, cash application, month‑end close, and compliance deadlines. Implement controls to reduce billing errors, speed cycle times, and improve audit readiness (even if no formal audit).
What Success Looks Like
Billing cycles are on‑time and accurate
, with fewer exceptions and rework.
Auto Task invoices, payments, and credits are reflected correctly in Xero with clean reconciliations.
AR aging improves…
