Accounting Manager - Billing & Operations

Job Description

About Us

5x5 Telecom delivers enterprise internet, VoIP, and managed services to businesses that can't afford downtime. We're the only carrier with redundancy at all on-net projects, and our installations typically take 1–2 days rather than weeks. We're now bringing our accounting and bookkeeping functions in-house, and we're hiring the person who will own them.

The Role

You will own 5x5's day-to-day accounting and billing: AP, AR, collections, general ledger, reconciliations, customer account setup in our telecom billing platform, and the monthly close. You'll maintain GAAP-compliant, accrual-basis books, produce monthly financial statements and supporting schedules, and reconcile the billing platform to the GL.

You'll also spend a meaningful part of every day on the phone. Customers and vendors will call you about invoices, balances, credits, disputes, and payment status — and you'll call them to chase missing documentation, resolve discrepancies, and collect past-due balances. We need someone who is good at this and genuinely likes it.

Two things this job is not. It isn't a back-office role where you work exclusively in spreadsheets; external communication is central, not incidental. And it isn't a management role where you delegate the detail work. This is a hands-on individual contributor position for someone equally comfortable booking an accrual, explaining a surcharge to a customer's office manager, and calling a vendor's AR department to sort out a duplicate charge.

What You'll Own

Monthly close and general accounting

• Run the complete monthly close independently — journal entries, adjustments, accruals, and cutoff accuracy across prepayments, deferred revenue, fixed assets, depreciation, payroll, and commissions

• Reconcile all material balance-sheet accounts monthly (bank, credit card, merchant processing, loans, payroll), and resolve differences rather than carrying them

• Prepare monthly financial statements and supporting schedules for management

• Maintain the chart of accounts, documentation, and a clean audit trail

• Flag unusual transactions, control gaps, and financial risks early

• Support our outside CPA, tax preparers, auditors, and lenders

Billing, AR, and collections

• Set up new customer accounts in the telecom billing platform — entities, addresses, billing contacts, terms, tax status, service dates, recurring and one-time charges, discounts, and surcharges — accurately and before the first invoice goes out

• Process service changes, upgrades, downgrades, moves, renewals, and cancellations

• Issue invoices, apply payments and credits, and reconcile the billing platform to the GL

• Review billing data for missed charges, wrong rates, unauthorized discounts, and other revenue leakage

• Monitor AR aging and pursue past-due balances professionally and persistently

• Research disputes, unapplied and partial payments, and account discrepancies through to resolution

• Report to management on aging, collections, and material account issues

AP and vendor management

• Receive, code, verify, and enter vendor invoices; confirm approvals and correct period

• Schedule and process payments; maintain vendor records, W-9s, and documentation

• Reconcile vendor statements and chase missing invoices, credits, and incorrect balances

• Monitor recurring charges for unexpected increases, duplicate services, and billing errors

• Prepare month-end AP accruals and assist with annual 1099s

Customer finance support

• Be the person customers reach for invoice, balance, payment, credit, and autopay questions — by phone and email

• Investigate billing concerns end to end instead of handing them off

• Coordinate with sales, implementation, operations, and support to confirm billing matches what was sold and delivered

• Stay patient and solution-oriented in difficult conversations

• Identify recurring sources of customer confusion and fix the underlying invoice or process

Process and controls

• Write and maintain SOPs for recurring accounting and billing processes, plus a monthly close checklist

• Maintain controls over invoice approval, payments, refunds, credits, and account changes

• Protect confidential company, customer, employee, and banking information

• Build processes that scale as we grow

Required Qualifications

• 5+ years of progressively responsible accounting, senior accounting, or full-charge bookkeeping experience

• Demonstrated ability to run a complete monthly close independently, without an outside CPA catching routine errors

• Strong working knowledge of GAAP and accrual-basis accounting, including period cutoff judgment

• Hands-on experience across AP, AR, GL, close, accruals, reconciliations, financial-statement prep, customer billing, collections, and vendor management

• Ability to research a discrepancy and determine the right resolution on your own

• Strong spreadsheet skills — formulas, lookups, pivot tables, reconciliation work

• QuickBooks Online, NetSuite, Sage Intacct, or comparable

• Proven experience communicating directly with customers and vendors about invoices, balances, and disputes, and real confidence on the phone

• Ability to explain accounting and billing clearly to non-accountants

• Strong organization, attention to detail, and follow-through across competing deadlines

• Integrity and discretion with confidential financial information

Preferred Qualifications

• Bachelor's degree in accounting, finance, or a related field

• Recurring-revenue or contract-based billing experience — telecom, managed services, or SaaS — including prorations, service changes, credits, and cancellations

• Experience reconciling an operational billing platform or subledger to the GL

• Experience at a small or growing company where the accountant is both senior and hands-on

• Familiarity with sales tax, telecom taxes, and regulatory fees

• Experience with system integrations, migrations, or cleanup projects

• Experience preparing schedules for outside CPAs, reviews, or audits

• Experience writing accounting and billing SOPs

• CPA or public-accounting background welcome, not required

Who Thrives Here

You take ownership instead of waiting to be reminded. You know a reconciliation isn't done until the difference is explained, and you know the difference between entering transactions and maintaining books. You'd rather pick up the phone than trade five emails. You build real relationships with vendor reps and customer accounting contacts, and you're energized — not drained — by helping someone understand their bill. You document what you do instead of keeping it in your head. And you move comfortably between detailed accounting work and external conversations all day long.
