Your next source of revenue is often already in your CRM: customers who know you, trust your product and have already bought once. Yet most sales teams chase new logos and leave existing accounts alone until renewal.
Then a customer buys a second solution elsewhere because nobody asked, or a team doubles in size without anyone offering more seats. The opportunity was there. It just was not written down anywhere.
An account plan fixes that. Below: what to put in it, how to spot cross-sell and upsell signals, how to keep it alive and how to present it to your manager, with a template to copy.
What is an account plan?
An account plan is a short document that describes where you stand with a customer and where you want to take the relationship over the next six to twelve months. It answers three questions: what does this customer already have, what will they need next, and what are you going to do about it, by when?
Two terms come up all the time:
- Cross-sell: selling a different product or service to a customer who already buys from you. A customer using your software in one department adopts a second module.
- Upsell: selling more of what they already have, or a higher tier. More users, more volume, a premium plan.
An account plan is not a yearly report but a working tool of a page or two, updated after every significant conversation.
- A yearly report
- The whole org chart
- A document nobody opens after the first week
- A working tool of a page or two
- Focused on the next six to twelve months
- Updated after every significant conversation
What to put in an account plan
Keep each section short: this is a plan, not a history book.
- Organization and contactsWho decides, who uses, who supports you, who is skeptical
- HistoryWhy they chose you, deals won and lost, incidents
- What they already useProducts, quantities, teams and how much it is really used
- Upcoming needsEvents this year and the needs you could cover
- RisksEach risk named, with the action that reduces it
- Objectives and actionsTwo or three objectives, each action with an owner and date
1. Organization and contacts
List the people who matter, not the whole org chart:
- Who decides: who signs and who controls the budget.
- Who uses: the teams that work with your product every day.
- Who supports you: the internal champion who wants you to succeed.
- Who is skeptical: the person who would happily replace you.
Tip: Note the gaps too. Knowing only one person in a company of several hundred is both a risk and an opportunity.
2. History
Sum up the relationship in a few lines: when they became a customer, why they chose you, the deals won and lost since, and any incident that left a mark. Lost deals tell you what the customer bought elsewhere, and why.
3. What the customer already uses
Write down what they bought, in what quantity, for which teams, and how much it is really used. Low usage is an early warning. Strong usage in one team and none in the others often points to your next cross-sell.
4. Upcoming needs
List what is coming up for the customer this year: a new office, a reorganization, an acquisition, a project announced by management. Each event creates needs, and some match what you sell.
5. Risks
Common risks: a champion who is leaving, a new decision-maker who does not know you, budget cuts, unresolved support issues, a competitor present in another department. Name each risk and the action that reduces it.
6. Objectives and dated actions
End with two or three objectives and the actions that get you there. Each action has an owner and a date. "Explore expansion" is not an action. "Meet the head of logistics before October 15 to present the planning module" is.
How to spot cross-sell and upsell signals
Opportunities rarely announce themselves: they show up as small signals in meetings, emails and product usage:
- Growth: hiring, new sites, new markets. More people often means more seats.
- Usage at the limit: a team hitting its plan's limits or asking for higher-tier features.
- Workarounds: a spreadsheet kept alongside your product, an export done by hand every week. Each one points to a need you may already cover.
- Questions from other teams: when another department asks how your product works, it is a potential new user.
- Changes in people: a new manager brings new priorities, and sometimes a budget.
- Comments in passing: "we would love to do the same for our sales team" is a cross-sell opportunity said out loud.
Write each signal in the plan straight away, with the date and who said it. One that stays in your head is gone by the next meeting.
One rule above all: only propose what solves a real problem for the customer. An upsell they do not need will come back as a churn risk at renewal.

Example: a plan for a logistics customer
A filled-in plan for a fictional case: a staff scheduling software vendor and its customer, a logistics group.
- Contacts: the operations director signs, the finance director controls the budget, the head planner at the main warehouse is the champion. No contact yet in the transport division.
- History: customer for two years, chose the software to replace schedules built by hand. A deal for the time-tracking module was lost last year when the budget went to another project.
- Current usage: one warehouse, strong usage.
- Upcoming needs: a second warehouse opens in the spring, and the transport division still plans its drivers in spreadsheets.
- Risks: the champion mentioned she may move to another site. The finance director is reviewing all software spend for 2027.
- Objectives: extend to the second warehouse (upsell) and get a first meeting with the transport division (cross-sell).
- Actions: ask the champion for an introduction to the transport manager before the end of September. Prepare a cost comparison for the finance director before the 2027 budget talks in October.
Seven lines, two clear opportunities, and a risk handled before it becomes a problem.
Keep the plan alive from one meeting to the next
An account plan nobody opens after the first week is useless. Build updates into your routine:
- Before each meeting: reread the plan for two minutes and pick one question to ask. It fits naturally into your meeting preparation.
- After each meeting: add what you learned: a new contact, a new signal, a date that moved. Five minutes, while it is fresh.
- Every quarter: review the objectives: close those you reached, drop those that no longer make sense, set new ones.
Keep the plan in or next to your CRM, so a colleague can pick it up if you are away.
How to present your account plan to your manager
Your manager does not need every detail, just where the account stands, what you aim for and what you need from them. Keep it to five minutes:
- The situationWhere the account stands, in one sentence
- The opportunitiesWhat you want to sell, to whom, and roughly when
- The risksWhat could go wrong and what you are doing about it
- The next actionsEach one with its date
- Your askA meeting with an executive, a product expert, a commercial gesture
- The situation in one sentence: "A solid customer with strong usage in one warehouse, and two clear paths to grow."
- The opportunities: what you want to sell, to whom, and roughly when.
- The risks: what could go wrong and what you are doing about it.
- The next actions: with their dates.
- Your ask: a meeting with an executive, help from a product expert, a commercial gesture to approve.
Watch out: People often forget the last point. A good account review ends with a clear request, not a status update.
How a sales copilot helps you build account plans
The slowest part of an account plan is gathering the information: deal history, wins and losses, key figures. Orion, the Constellia sales copilot, does it from your CRM and prepares an account plan that highlights cross-sell and upsell opportunities. It can generate the plan as a PowerPoint, Word, Excel or PDF document in your company's colors, ready to share with your manager. You review it, add what only you know about the customer, and decide what comes next.
Start with one account
You do not need a plan for every customer. Pick the account with the most potential, fill in the template this week and bring it to your next meeting with that customer.
Your existing customers already trust you. An account plan makes sure you do not leave the next opportunity to someone else.
