Product Manager, Billing

Purpose and mission 

The Product Manager (PM) is the strategic owner of one or multiple product areas within Piano’s portfolio. The PM translates business goals, market signals, and client insights into a compelling product vision and a prioritized program backlog. They work at the intersection of business strategy, client value, product marketing, product design and technology feasibility, ensuring that the right things get built, in the right order, for the right reasons. 

In the SAFe 6 model, the PM operates at the Agile Release Train level, driving the Program Increment (PI) and empowering Product Owners to execute with confidence and autonomy. 

In an AI-accelerated product landscape, a PM at Piano is expected to actively leverage AI tools to sharpen market analysis, accelerate discovery, generate insights from data, and move faster at every stage of the product lifecycle. AI fluency is not optional — it is a force multiplier for every other responsibility in this role. 

The Billing PM owns Piano’s subscription billing infrastructure — the engine where subscriptions are created, invoiced, upgraded, renewed, and managed through Stripe Billing. Piano is in the midst of a large-scale platform transformation, replacing its internal billing engine with Stripe Billing across every subscription lifecycle event. This is not a surface-level product role. The PM operates deep inside billing logic: proration, upgrade and downgrade flows, dunning, invoicing, term management, and the integration boundary between Piano’s orchestration layer and Stripe’s billing primitives. The right PM has done this before — they’ve integrated Stripe Billing at scale, they understand what breaks when billing logic gets complex, and they move fast without breaking revenue. 

Core responsibilities 

1. Product Vision & Strategy 

Co-develop and maintain a clear, compelling product vision for Piano’s billing domain in close partnership with Product Leadership, aligned with Piano’s broader subscription platform strategy. As the domain matures beyond initial transformation, this role is expected to grow into full strategic ownership of the billing product area. 

Develop and own the billing roadmap over a 3–12 month horizon, balancing new capabilities, technical quality, and business priorities. 

Conduct ongoing market and competitive analysis to identify opportunities, threats, and strategic positioning — particularly in the billing and monetization infrastructure space and at the boundary between Piano’s orchestration layer and Stripe Billing capabilities. 

Track Stripe’s product roadmap and shipped capabilities to identify opportunities for Piano — know when Stripe solves a problem natively versus when Piano must build. 

Define and communicate product positioning, target segments, and go-to-market priorities in collaboration with Marketing and Sales. 

2. Backlog Ownership at Program Level 

Own and maintain the billing Program Backlog (Features and Enablers) in collaboration with Product Leadership, Architects, and other PMs. 

Prioritize features using value-based frameworks (WSJF, RICE, business impact, strategic fit) and maintain a rolling, well-groomed backlog at all times. 

Lead PI Planning preparation for billing: define PI Objectives, present the roadmap to the ART, and make prioritization decisions during planning. 

Validate Feature acceptance criteria before development begins and approve Features upon delivery. 

3. Stakeholder Alignment & Communication 

Serve as the primary voice of the customer and the market within the ART for billing-related work, translating needs into Features the team can act on. 

Collaborate closely with Sales, Pre-Sales, Customer Success, and Support to gather and synthesize client feedback on billing pain points, invoicing requirements, and subscription management needs. 

Communicate the roadmap and strategic priorities clearly and consistently to all relevant stakeholders, including executive leadership. 

Represent the product in customer-facing contexts: executive meetings, key account workshops, conferences, and strategic partnership discussions. 

4. Business & Performance Management 

Define and monitor billing product KPIs and OKRs, with particular focus on billing accuracy, subscription lifecycle efficiency, revenue recognition, churn impact, and integration reliability. 

Conduct product ROI analysis to justify investment decisions and support budget and resource discussions. 

Manage the billing product lifecycle from inception to end-of-life, making proactive portfolio decisions in collaboration with Product Leadership — including managing the transition from transformation mode to steady-state innovation. 

5. Go-to-Market & Launch 

Lead the go-to-market strategy for new billing capabilities and major releases: beta programs, internal training, sales enablement, and release communication. 

Collaborate with Marketing and PMM teams to produce effective product messaging, particularly around billing flexibility and subscription management as competitive differentiators. 

Define and oversee the internal release process to ensure teams are prepared before customer-facing delivery. 

Collaboration model 

The PM does not work in isolation. Success in this role depends on effective collaboration: 

With Product Leadership (VP, Product and at the ART and Portfolio levels): The Billing PM works in close partnership with the VP who owns the strategic platform vision. Key decisions on scope, investment, and direction are made jointly. The PM brings domain expertise, execution judgment, and market intelligence; Leadership provides strategic framing and cross-product alignment. 

With Product Owners: POs are assigned per initiative. PMs provide strategic context, prioritized Features, and clear acceptance criteria. POs translate these into actionable stories. The PM should be a trusted partner and enabler for POs, not a bottleneck. 

With Architecture & Engineering: PMs work with Architects to understand Stripe Billing’s technical constraints, integration patterns, and platform capabilities. Technical feasibility informs prioritization and roadmap planning. 

With Product Design: The PM sets the user experience ambition, defining the problems to solve, the user outcomes to target, and the quality bar expected. For billing, clarity and reliability of billing-related surfaces are core inputs to design decisions. 

With Customer Success, Consulting & Support: The PM ensures proactive knowledge transfer before releases, clear internal documentation, and well-defined escalation processes, so that client-facing teams can resolve billing issues and answer questions with confidence, without systematically falling back on Product. 

With GTM teams: PMs are responsible for enabling Sales, Pre-Sales, and Marketing to confidently present and sell Piano’s billing capabilities at all times. 

What success looks like 

The billing roadmap is clear, up-to-date, and well understood by all stakeholders — reflecting both the platform strategy and the realities of Stripe Billing integration. 

PI Objectives are ambitious yet realistic and are consistently met or exceeded. 

Product Owners feel empowered, well-informed, and able to operate autonomously within their initiatives. 

Billing drives measurable business value: subscription lifecycle efficiency, billing accuracy, revenue impact, and client satisfaction with billing operations. 

The team builds the right things, validated by client outcomes and revenue impact, not just delivery volume. 

Stripe’s evolving capabilities are tracked and leveraged proactively — the PM knows when to build and when to wait. 

Field teams (Pre-Sales, Sales, Client Success…) are informed ahead of releases, equipped with the right materials, and feel like active contributors to the billing roadmap, not just recipients of it. 

Strategic changes and trade-offs are communicated proactively and with confidence.
