Hi, I’m Emilia. I hold a Bachelor's Degree in Business Administration and specialize in helping small businesses understand and organize their costs. While many bookkeepers focus only on recording transactions, my work goes a step further. I help business owners track their day-to-day expenses, structure their monthly costs, and gain visibility into where their money is going. I work closely with clients to organize operational expenses, payroll costs, and recurring business spending using structured Excel or Google Sheets systems. By tracking expenses consistently, we can identify spending patterns, detect inefficiencies, and make better financial decisions. A typical workflow with my clients includes tracking business expenses throughout the month and then reviewing the cost structure together. During these reviews, we analyze where the business may be overspending, where costs could be optimized, and what upcoming expenses may look like. My goal is to give business owners a clear and simple view of their financial operations so they can focus on growing their business while maintaining control over their costs. Services I provide: Cost & expense tracking - Daily and monthly business expense tracking - Payroll cost organization - Categorizing operational costs - Expense dashboards in Excel / Google Sheets Cost Analysis & Financial Organization - Identifying areas where spending can be optimized - Reviewing cost structures with business owners - Monthly cost reports and financial summaries Bookkeeping support - Accounts payable & receivable tracking - Transaction reconciliation - Financial data organization Tools: • Excel • Google Sheets • Expense dashboards • Cost tracking systems • QuickBooks (support level) Many small businesses struggle not because of revenue, but because they don’t clearly understand their cost structure. My role is to help bring clarity to those numbers!

What does an Invoicing specialist do?

An invoicing specialist prepares, reviews, and issues customer invoices to secure timely payment for goods or services. This role bridges the gap between completed work and collected revenue by translating operational data into accurate billing documents. The specialist verifies that every charge aligns with contracts or service tickets before submission. They also track each invoice through the approval process to resolve disputes and maintain clear receivables records.

  • Review billing inputs such as service tickets, contracts, or job data to verify that amounts, tax codes, and customer profiles are correct. Investigate any discrepancies in the source data and coordinate with internal teams to correct errors before generating the final document. This step prevents rejected invoices and reduces the need for later corrections or credit memos.
  • Prepare and submit customer invoices through designated channels, which may include specific client portals, email systems, or enterprise resource planning platforms like Vista by Viewpoint ERP. Follow customer-specific submission guidelines precisely to avoid administrative delays. Export or print supporting documentation when required by the client’s accounts payable department.
  • Monitor invoice status after submission and follow up on items marked as pending, rejected, or disputed. Communicate directly with customer accounts payable contacts to obtain remittance details and clarify billing questions. Update internal tracking logs to reflect the current state of each invoice and ensure no bill falls through the cracks.
  • Maintain detailed billing records, including invoice status tracking logs and receivables aging reports, using tools like Excel or specialized software such as OpenInvoice. Analyze these reports to identify overdue payments and prioritize collection efforts. Keep all digital files organized so that audit trails remain complete and accessible for finance teams.

How to hire an Invoicing specialist on Upwork

Step 1: Post a job

Define the specific billing workflows and accounting systems your business uses to attract qualified candidates. The Job Post Generator powered by Uma™, Upwork's Mindful AI drafts a complete job post after you describe your needs in a few sentences. You can write a new post, update a saved draft, or reuse an existing post to start your search.

  • List required experience with accounts receivable systems such as SAP AR or Vista by Viewpoint ERP to handle job setup and tax details accurately.
  • Specify proficiency in Excel for maintaining tracking logs and generating receivables aging reports that reflect current invoice status.
  • Clarify whether the role involves submitting invoices through platforms like OpenTicket and OpenInvoice or communicating directly with customer AP departments.

Step 2: Evaluate candidates

Look for portfolios that demonstrate accuracy in high-volume billing environments and clear documentation of resolved discrepancies. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to help you assess communication skills and attention to detail.

  • Review samples of invoice correction documentation to see how the candidate investigates and fixes billing errors with internal teams.
  • Check for evidence of maintained tracking logs that show consistent follow-up on pending, rejected, or disputed invoice items.
  • Evaluate examples of receivables aging reports to confirm the candidate organizes outstanding balances clearly for internal review.

Step 3: Interview your top choices

Discuss specific scenarios involving billing discrepancies and customer communication to gauge problem-solving abilities. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session for your records.

  • Ask how they verify invoice amounts and codes against service tickets or contracts before submission to prevent downstream errors.
  • Request examples of how they communicate with customer contacts to obtain remittance details and support internal payment processing.
  • Discuss their process for updating billing records when an invoice is rejected or requires replacement due to documentation issues.

Step 4: Agree on scope and begin work

Set clear milestones for invoice volume, accuracy targets, and reporting frequency to align expectations from day one. Use Upwork Messages and the contract workroom for all communication and project management, while identity verification, Hourly Payment Protection, hourly tracking, and project funds secure the engagement.

  • Define the weekly volume of customer invoices to prepare and submit through your designated invoicing channels or platforms.
  • Establish a schedule for submitting invoice status tracking logs and receivables aging reports to keep your financial data current.
  • Outline the protocol for resolving billing discrepancies, including who contacts customer AP departments and how corrections are documented.
