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-charg
