A guide to effective finance business partnering with Christian Wattig

The short version

If you're only weighing in after decisions are made, you're not a finance partner. You're a scorekeeper. Finance business partnering means you're in the room before the decision gets framed, helping shape the outcome rather than reporting on it.

Most finance teams know they should be more strategic, but the calendar disagrees. Close eats the first week, reporting eats the second, and ad-hoc requests eat what's left. The result is a team that wants a seat at the decision table but can't find the hours to earn one.

Christian Wattig is the director of the Wharton School's FP&A Certificate Program and a veteran of Procter & Gamble, Unilever, and Squarespace, where he was part of the team that took the company public. He joined Ramp's Patrick Yang to break down what it takes to move from back-office reporting to a real seat at the table.

If you want to go deeper on the scenario planning side of his FP&A work, he covers that in a separate Ramp webinar: How to Build Scenarios Like a Wharton Program FP&A Leader.

Most useful for: FP&A managers, finance directors, and CFOs who want a seat at the table before the decision, not after.

What is finance business partnering?

Finance business partnering is the practice of working directly with non-finance departments to influence decisions, drive strategic value, and improve business performance. It moves finance out of a cost-center reporting role and into an active strategic partnership, with the team bringing forward-looking insights, financial modeling, and actionable recommendations into the rooms where decisions get made.

In practice, the work falls into three overlapping rhythms: helping leaders frame the decision before they commit, aligning departmental plans with corporate goals, and tracking what actually happens against the plan in real time. Strong finance business partners do all three, then translate the output into a story business unit leaders can act on.

Christian Wattig's 1-to-5 maturity scale further down maps exactly where a team sits on that journey, and his five tips give you a concrete way to climb it.

Christian's 4 pillars of finance business partnering

Before the maturity scale, Christian frames the role itself as four interlocking pillars at the intersection of empathy and business acumen. They show up at every level of the work, regardless of company size or industry.

• Raising accountability: Pointing to what's actually causing performance or a variance against expectations. Not finger-pointing, but peeling the onion until the root cause is clear.
• Simplifying and questioning: Most companies have more data and information at their fingertips than leaders can reasonably absorb in a day, especially with real-time feeds. Finance plays the role of filter and picks out the metrics that matter right now, then asks the questions that surface what's underneath them.
• Creating visibility: Spotting metrics nobody currently tracks but that could help leaders make better decisions. New leading indicators and operational metrics that tie back to strategy and financial performance.
• Influencing and empowering: Departmental goals are often narrowly defined, like a sales team focused on volume while paying less attention to profitability. Finance is uniquely positioned to connect the dots because it has access to information across systems and a bird's-eye view of the business.

The pillars sit underneath everything that follows.

What does strategic finance business partnering look like?

Christian uses a 1-to-5 maturity scale to turn the vague idea of "strategic finance partnering" into something you can actually measure on your own team.

A 1 is roughly 90% transactional, the cycle of close, slides, ad-hoc, forecast, and repeat. A 3 means you're pulling data from across the business into a clear financial narrative and getting useful inputs from partners on variances. A 5 is when leaders proactively come to you before a decision gets made. That single behavior, who picks up the phone first, is the cleanest test of where you sit.

If you polled your own team, you'd likely land around a 3, which is where most of Christian's live audience fell. The gap between a 3 and a 5 is rarely technical, but relational instead. Partners share early-stage information when they trust you to help them win rather than police them, and that's what makes every other tactic in this post work.

1. Most teams self-rate a 3. The gap is who calls first

The 1-to-5 poll distribution clustered around 3, which is where most teams self-rate. Most have moved past pure reporting, but few have crossed into proactive partnership. The behavior that defines a 5 isn't a better dashboard or a faster close. It's the leader from another department picking up the phone before the decision gets framed.

"This is what separates a three from a five, where leaders come to you proactively, before making a big decision. That's a sign that you're close to a five, when on a regular basis, leaders from across the company come to you as the finance leader and say, hey, we're considering launching a new marketing channel. I'd love for you to look at the data, run an analysis, and let me know what you think. If that happens on a regular basis, then you have a seat at the table where the decisions are made."

2. The biggest barrier is time, with 3 root causes

Over half of poll respondents named "lack of time, buried in transactional work" as their top barrier to becoming more strategic. This isn't a willpower problem, but three problems stacked.

1. Data quality at the source: If you're heavily manipulating data after extraction, the fix usually lives in the source system. It's unglamorous and time-consuming work that rarely gets done while you're also running the close.
2. Process triage: If you're sending 10 reports, you might find only three actually drive decisions. Have honest conversations with your partners about what they need, then cut the rest.
3. Tools that don't require IT: You can implement modern FP&A, AP, AR, and spend management tools yourself. Many take days, not months, to set up.

Working harder on just one of these rarely makes a difference, so all three need attention. Christian also recommends running side-by-side comparisons through ChatGPT, Gemini, or Copilot to get a more unbiased read on tool features before sitting through demos.

"I see so many finance teams that are still basically entirely in Excel, that build their slides by downloading the data in Excel and then pasting it into PowerPoint, and that don't make use of tools that are available to automate so much of your work, to save so much of your time. These tools are getting better and better. There are a lot on the market now for any price point, on the FP&A side as well. So it's definitely worth looking at those tools."

3. Trust is the flywheel input. Extend it first

Trust is the one thing that makes everything else work. Christian grounds this in Google's Project Aristotle, which found that psychological safety, not team composition or after-work bonding, drove the best teams.

He translates this into a finance-specific flywheel:

1. Trust leads to better relationships
2. Better relationships lead to earlier information sharing
3. Earlier information sharing lets you prove you can do more than cut budgets and update forecasts
4. That proof deepens trust, and the cycle keeps spinning

The starting move is to extend trust first, which means being consistent, hitting commitments by when you said you would, and making it clear your goal is helping partners win rather than policing them. A marketing leader exploring a new channel won't share it with you if they expect your first move to be cutting their budget.

"The fastest way to build trust is to extend trust, to show other leaders that you are trusting them, to be very consistent in your performance. When you say you'll do something by x, you're actually doing it by then. That's the foundation."

4. Finance defaults to 1 or 2 of 5 influencing styles

Christian walks through five influencing styles and the situations each one fits.

• Rationalizing: Logic, facts, evidence-based arguments. The finance default.
• Asserting: Confidence, rules, authority. Best in a crisis or when something is black and white.
• Negotiating: Compromise, meeting in the middle. A bad fit for binary investment decisions.
• Inspiring: Shared mission, stories, metaphors. Best for creative or daunting work.
• Bridging: Reciprocity, coalitions, consultation. Common in board-level decisions.

Most of us reach for rationalizing by default. Christian's fix is a 1-week influencing journal, where every time you try to influence someone at work, you write down which style you used. The pattern becomes obvious fast, and so does the muscle you need to build next.

He pairs this with two operating principles. Think lawyer, not police officer, because a lawyer helps partners reach their goal while staying on the right side of the rules. Think process, not people, because when something goes wrong the durable fix is usually a process change rather than a one-time conversation.

"A lawyer wants to help you reach your goal while helping you stay on the right side of the law. So a lawyer helps you navigate gray areas. Gray areas are often where we can add a lot of value because rules are important, but they can't anticipate every situation. The more senior you get in a role, in a business, the more you learn that some rules can be bent. There really are gray areas. Not everything has to be seen as black and white."

5. Coach instead of compete on subject-matter expertise

When you're not the subject-matter expert in the room, coach instead of compete. Christian's anchor for this is Michael Jordan, who hired a coach at the height of his career not because the coach knew more about basketball, but because the right question at the right time improved his thinking.

The framework Christian recommends is GROW.

1. Goal: Help the team clarify what they're trying to achieve. His go-to question: "Assume you have unlimited people, time, and money. What would be possible?"
2. Reality: Help partners check assumptions. Teams often think their situation is unique when you've seen something similar elsewhere in the business.
3. Options: Where you most often break groupthink. Ask "what else could we do?" before the room commits to the first idea raised.
4. What's next: Commit to a game plan. Christian's preferred close: "On a scale of 1 to 10, how well-equipped do you feel to succeed?" The scaled question surfaces gaps the binary version misses.

"What I often see is that teams rush to the first or second idea that comes up. And often that's driven by groupthink. Someone in the room has an idea, and everyone in the room agrees. And because everyone agrees, it must be a fantastic idea. So we should go ahead and do it. But there might be other options that just weren't considered yet that could actually be more effective, more efficient. So ask, what else can we do? Just by encouraging people to take the step back and really think more broadly, you can improve decision quality."

The 4 core responsibilities of a finance business partner

Christian's five moves are tactics within a broader role. Stepping back, the work of a finance business partner breaks into four interlocking activities that show up across every team and industry.

1. Decision support: Constructing the business case for a proposed investment and running scenario analyses to pressure-test the assumptions before commitments get made. This is the highest-leverage piece of the job, and Christian's 1-to-5 maturity scale above uses it as the test for whether you actually have a seat at the table.
2. Integrated planning: Running the forecasting, budgeting, and quarterly close cadence so each department's plan plays to the company's full-year strategy. Done well, this pulls sales, marketing, and operations into one financial narrative rather than reconciling four separate versions of the truth at quarter end.
3. Performance management: Monitoring KPIs, breaking down variance against plan, and surfacing risks and opportunities before they compound. This is the part of the job most finance teams are already doing, and the part Christian's "biggest barrier is time" tactic above shows how to streamline.
4. Storytelling with data: Turning the output of forecasts, variance analyses, and scenarios into a clear, actionable narrative your partner can defend to their own team. The frameworks for this sit upstream of dashboards. They live in how you filter the noise and ask the right questions, which is exactly what Christian's "simplifying and questioning" pillar above is built around.

Most finance business partners do all four already. The difference between competent and effective is which one you spend the most disciplined time on.

Core skills every finance business partner needs

The technical skills (modeling, variance analysis, forecasting) are the floor, not the ceiling. The skills that actually separate effective finance business partners from competent FP&A analysts are non-technical.

• Business acumen: Reading the company's strategy and the operational drivers that actually move the P&L. Without it, every conversation feels like an outsider explaining your business back to you.
• Communication and influence: Working with stakeholders well enough that they bring you decisions before the commitment, not after. Christian's five influencing styles above (rationalizing, asserting, negotiating, inspiring, bridging) are the practical version of this skill.
• Analytical skills: Pairing data visualization with predictive analytics to extract the insight a static report misses. The shift is from reporting what changed to recommending what to do about it.
• Strategic thinking: Spotting the connections across departmental data that your partners only see in their own slice, and surfacing the opportunity ahead of them. Christian's GROW coaching framework above is built for getting more strategic thinking out of every meeting you're in.

Most finance professionals reach the technical floor by year three. The skills above are what define the next decade of the career, and the moves above are how Christian's playbook builds them.

Benefits of finance business partnering

The case for finance business partnering is operational, not theoretical. When the work is done well, three benefits compound over time.

• Improved decision-making: When finance and operations work from the same plan and assumptions, business cases get pressure-tested before resources commit. Bad ideas die earlier, good ideas move faster, and decisions take less rework. Christian's 1-to-5 maturity scale above maps this directly: at a 5, decisions get framed with finance in the room rather than judged after.
• Proactive risk management: When finance is plugged into operations across the business, a shift in one department's numbers gets flagged the same week it surfaces, not at quarter end. Strong partnerships shorten the gap between "something just changed" and "the team has a mitigation plan."
• Increased value creation: Finance moves from being the team that reports on cost to the team that influences where capital actually flows. The trust flywheel Christian describes above is what makes this shift sustainable, since each consistent cycle deepens the relationship and unlocks the next decision earlier.

The benefits don't show up the week you start. They compound over quarters of consistent partnership work, which is why the maturity scale matters more than any single win.

How do you apply Christian's advice this quarter?

You can start all three of these this week.

1. Run the 1-to-5 self-assessment on your own team: Write down where you are, then write down one specific behavior that would move you up by half a point. Send it to your CFO or your manager.
2. Start the influencing journal: For 7 days, log every time you try to influence someone at work and which of the five styles you used. At the end of the week, pick one underused style to practice next week.
3. Cut one report: Identify a recurring report you produce that no one uses to make decisions. Email the recipients, ask if anyone would notice if it stopped, and if the answer is no, kill it. Use the recovered hours for one new touchpoint with a partner on another team.

Final thoughts

"When you have trust, your relationships improve, people are more willing to put themselves out there, share data early with you as the finance leader. Then you can demonstrate that you can do more than cutting budgets or updating forecasts, that you can help them reach their goals, that you can help them argue for more funding where it makes sense. And demonstrating that then improves trust, which improves relationships, which leads to more collaboration, and then this flywheel just keeps spinning."

The pattern across every framework in this webinar is the same: you earn a seat at the table by being useful before the decision, not after. That means extending trust first, practicing your influence styles deliberately, and learning which questions to ask in rooms where you're not the expert.

See how Ramp fits in

Most of the time you lose to transactional work before the close even starts. Chasing receipts, coding expenses, processing bills, and reconciling cards. You can reclaim those hours by consolidating cards, expenses, bill pay, and procurement on one platform. With Ramp, you can automate that work so your team can focus on the partnering work Christian describes.

Common questions about finance business partnering

What is finance business partnering, and how is it different from traditional FP&A?

Traditional FP&A is primarily backward-looking. You close the books, report the variance, and update the forecast. Finance business partnering is the opposite because it's forward-looking.

As a finance business partner, you attend planning meetings and challenge assumptions before a budget is submitted. You help department heads understand the financial implications of decisions they haven't made yet. The difference isn't the tools or the data, but the timing. You're in the conversation before the decision, not after.

What does a finance business partner actually do day to day?

A finance business partner spends time across four interlocking activities: building business cases and decision-support analyses for partner teams, driving integrated forecasting and budgeting cycles, tracking KPIs and variance against plan, and translating numbers into stories that business unit leaders can act on. The mix shifts by company, but the highest-leverage portion is decision support, since that's what earns the seat at the table before commitments get made.

What skills does a finance business partner need beyond technical finance?

You can take the technical floor (modeling, variance analysis, forecasting) as a given. What sets you apart is what sits on top of those skills: business acumen, communication and influence, analytical skills, and strategic thinking.

Christian's influencing styles framework (rationalizing, asserting, negotiating, inspiring, bridging) maps directly to the non-technical skills most finance professionals never formally develop. The GROW coaching framework addresses another gap: knowing what to contribute in a room where you're not the expert.

What are the benefits of strong finance business partnering?

The three benefits that show up consistently are better decisions (because finance helps frame them before they get committed), proactive risk management (because finance sees risk and opportunity in real time across departments), and increased value creation (because finance shifts from reporting cost to influencing where capital goes). Each benefit compounds over time, which is why the maturity scale matters more than any single quarter's wins.

What is the fastest way to free up time for partnering work?

Cut one recurring report this week. You probably produce at least one report nobody uses to make decisions, and it persists because no one's had the conversation to retire it. Once it's gone, redirect the recovered hours into one new touchpoint with a partner on another team rather than a different reporting task.
