How to Build a Whitespace Grid That Drives Real Expansion.
You are preparing your quarterly account review and want to find genuine growth opportunities, not just a list of products you could theoretically sell
Most AMs know their accounts have untapped potential but cannot point to it precisely. A whitespace grid turns a vague feeling into a visual map with rough revenue attached to each gap. That makes it easy to prioritise, easy to discuss with your manager, and easy to bring into a customer conversation with a clear business case rather than a pitch.
Where it goes wrong
Without a grid you default to selling whatever is top of mind or whatever your quota pushes. You miss whole business units, regions, or use cases that would be obvious if you looked at them side by side. Expansion becomes reactive rather than planned.
What you'll be able to do
You can build a simple whitespace grid for any account, attach a rough revenue estimate to each gap, and pick one area to pursue this quarter with a clear next step and owner.
How to do it
Draw a two-axis grid
Draw a two-axis grid: your products or modules across the top, the customer's business units or regions down the side. Fill in what is live, what is under-adopted, and what is blank.
For each blank or under-adopted cell, write one sentence
For each blank or under-adopted cell, write one sentence: the business problem you solve there and a rough ARR estimate (e.g. 3 teams x 40 users x $X per user). Skip cells where you have no plausible story.
Before chasing a blank cell, check adoption in the
Before chasing a blank cell, check adoption in the cells you already own. A module at 40% adoption is a better first conversation than a brand-new sale - fix that first, then use the success story to open the adjacent door.
Pick one whitespace area per quarter to pursue actively
Pick one whitespace area per quarter to pursue actively. Name the likely economic buyer, the dependency you need to resolve, and the specific next step.
See the difference
The AM notes in Salesforce: 'Opportunity to expand into EMEA and sell workforce module.' No numbers, no buyer named, no next step. It sits there for six months.
The AM builds a grid for Contoso. Customer Care in North America is live at 80% adoption. Two blank cells stand out: EMEA support team (estimated $150k ARR) and a workforce management integration ($80-100k ARR). She picks EMEA for Q3, names the regional VP and director of operations as the buying centre, and books a value review using North America results for the July QBR.

How you'll know it's working
You have got it when you can open your grid in a forecast meeting, point to a specific cell, name the buyer, and give a rough ARR number - without having to look anything up.
