OVERVIEW:
We’re seeking a meticulous and proactive Amazon DSP Billing & Collections Specialist to join our Finance team. This role owns the end-to-end billing and collections process for our Amazon Demand-Side Platform (DSP) product — which includes pass-through media costs — and acts as the financial control point between client invoicing and vendor payments. You’ll communicate with all stakeholders, manage reconciliations, monitor client balances, handle escalations, and improve billing workflows with a strong focus on accuracy, service, and cash flow integrity. 
 
This role partners closely with our DSP Strategists to align monthly client budgets with invoicing, and with Biz Ops to improve automation and reporting. You’ll serve as the central point of contact for outstanding invoices, service holds, and account balance tracking — for both SMB and Enterprise client portfolios. 
 
You will report to our Controller and be expected to operate with high autonomy, while escalating exceptions when needed. 

REQUIREMENTS:

•  2-3+ years in billing, collections, accounts receivable, or revenue operations, preferably in a digital advertising or SaaS environment. 

•  Strong understanding of billing systems (e.g. QuickBooks, Stripe), and CRM tools like Salesforce or equivalent. 

•  Advanced spreadsheet skills (Excel) for reconciliation, reporting, and exception tracking. 

•  Excellent written and verbal communication skills — you’ll interface directly with clients and internal teams. 

• Comfortable working in a dynamic, fast-paced environment with shifting priorities 

• Proven ability to work independently in a remote environment and manage tasks with high accountability. 

•  Experience reconciling media spend, pass-through costs, or vendor payments is a strong plus. 

•  Familiarity with digital advertising campaign billing models or agency invoicing is a plus. 

•  Fluent in English. 

….. If you reached this point, we hope you're feeling excited about the job description. We're eager to meet people that believe in Quartile's mission and can contribute to our team in a variety of ways. Feel welcome to apply!

WHAT YOU’LL DO:

• Manage the billing and collections lifecycle for all DSP clients, from monthly invoicing to reconciliation and payment follow-up. 

• Reconcile client deposits vs. media spend on Amazon and ensure all balances are accurate and up to date. 

• Act as the internal and external main point of contact for DSP billing inquiries, overdue payments, and budget clarifications, ensuring positive and professional client communication. 

• Partner with DSP Strategists to align on client budgets and campaign pacing. Pause services when balances are unpaid or thresholds are exceeded. 

• Monitor and report on account balances, aging receivables, and exceptions; escalate critical issues to Finance leadership. 

• Consolidate and document DSP billing processes across both SMB and Enterprise teams, ensuring consistency and control. 

• Collaborate with Biz Ops and Finance stakeholders to automate billing workflows and improve reporting accuracy. 

•  Assist with month-end close, internal reporting, and ad hoc reconciliation requests.
