2. The arithmetic nobody had done
Forty-six days of remaining path against twenty-two days of calendar. The signature date moved three weeks ago; it just had not been written down anywhere.
3. The sentence
Tomas Ballard has to get the accessibility report booked for 9 September, or Hana Vance cannot sign off, the requisition cannot be raised, and Ostara's capital budget closes without us in it.
Four of the five steps on the path came out of a single row originally labeled Procurement and security. Nothing on that row had an owner with a name.

How to create a mutual action plan
A mutual action plan is a document a seller and a buyer share, listing every step between today and a signed contract. Each step has one named owner, a due date and whatever it needs, such as a security report or a tax form. A good one covers the buyer's internal steps as well as yours, is dated backward from their deadline, and gets updated on every call.
Test each row by reading it aloud as a sentence that starts with a person's name. "Dana Ruiz signs off on the security review by September 4" is a plan. "Procurement, mid-September" is a hope.

When to start a mutual action plan
Propose the plan once the buyer agrees there's a problem worth solving and a date that matters to them. Frame it as their project, not your forecast: "Can we write down what has to happen on both sides for you to be live by February?"
Work backward from the date they care about, usually a go-live tied to something real, such as an audit or a busy season. Subtract implementation time to get the signature date.
The shared plan fits on a page or two:
The goal in the buyer's words, and the date it depends on
The people on each side, by name and role
Each step to signature, with one owner, a due date and a status
Dates neither side controls, such as a budget deadline
What each side is doing next
Share the plan, keep the tracker
The buyer sees the short plan. Your tracker holds the full detail, including notes on their people.
Map how they actually buy
Don't ask how purchasing works there. Ask what happened last time: "Walk me through the last tool your team bought, not what should have happened but what did." A described process looks like an org chart. A remembered one includes the delays.
Do this on a call, stage by stage. By email you'll get "the usual process, about three weeks," and nothing you can plan against.
Questions that turn each stage into steps
Stage
Ask
Listen for
Security
"Who signs off, by name, and what do they need from us?"
Questionnaires, audit reports, a review queue
Procurement
"Do we register in a supplier portal? What does it ask for?"
Tax forms, insurance, bank checks, a code of conduct
Finance
"Who raises the purchase request, and who approves it at this amount?"
Approval limits, a cost center, the budget deadline
Legal
"Who reviews the contract, and is anyone away before our date?"
Turnaround time, leave, whose contract you start from
Signature
"Who signs at this value, and how?"
Signing authority, an e-signature tool
Note every name you hear, with their role. A stakeholder and champion map shows who has to sign off and who you still need to meet.
Break each stage into named steps
Give every row one person, never a team. If nobody can be named, the step is too big or its owner is unknown. Split the first kind. For the second, write "unnamed" and ask on the next call.
Some buyers also ask to be named as an additional insured. IRMI, an insurance reference publisher, defines that as an organization added as an insured under your policy at your request2. Your usual certificate won't do: the policy itself has to cover them, so ask your broker early.
The buyer may also confirm your bank details by phone before paying you. That check guards against business email compromise, where criminals use hacked email accounts to redirect payments. The FBI's Internet Crime Complaint Center reports $55 billion in exposed losses3 from it between 2013 and 2023, and advises verifying account changes through a second channel. Ask who in accounts payable makes the call.
ExampleOne procurement row, taken apartAn illustrative example written for this guide. The people and durations are made up.
Before: Procurement. Owner: their procurement team. Due: mid-September.
Register in their supplier portal: Sam Lee (your deal desk), 1 day
Send Form W-9: Sam Lee, same day
Insurance certificate naming them as additional insured: Sam Lee, through your broker, 7 days
Sign their code of conduct: Ana Ortiz (your counsel), 2 days
Confirm bank details by phone: unnamed, their accounts payable, 2 days
Raise the requisition with a cost center code: Raj Patel (their operations lead), 3 days
Four rows are yours. Most of it is paperwork you control, so you can start today.
One owner is unnamed. That's your question for the champion on the next call.
Security splits the same way: the questionnaire, follow-up questions, any required audit report, such as a SOC 2, and the reviewer's sign-off. A security questionnaire response template helps with the answers. If finance needs a business case attached to the requisition, give it a row.
Date each step from your own deals
Date steps from evidence, not a template's defaults or the buyer's optimism. Bent Flyvbjerg, who studies why big projects overrun, recommends reference class forecasting: basing a forecast on how comparable past projects actually performed4. For a sales plan, those projects are your closed deals.
Pull dates from recent closed deals, lost ones included: a deal that died in legal still spent weeks there. For each step, note the median, the worst case and the number of deals. Below a minimum you set, such as eight deals, plan on the worst case.
1
Start at signature
List what must happen just before it, then before that, until you reach a step that can start today.
2
Add up the days
Total your own durations for the steps on that chain. That chain is your critical path.
3
Compare with the calendar
If the chain is longer than the days left, the date has already moved. Say so, with the number.
4
Name the one step
Write one sentence: the step, its owner, its date and what happens to the deal if it slips.
Then find the dates neither side controls: a budget period closing, an approval committee that meets monthly, a reviewer's vacation. Budgets that expire create a rush to spend. Economists Jeffrey Liebman and Neale Mahoney found US federal procurement spending in the fiscal year's last week was 4.9 times the weekly average for the rest of the year5.
Ask when the buyer's budget period closes. If that falls before your signature date, it's your real deadline.
Update it on every call, and keep the history
Open each call with the plan. Mark steps done on the date they actually finished, add new steps you've learned about, and confirm who owns what's next.
When a date moves, don't overwrite it. Keep the original in its own column, put the new date beside it, and log who moved it and why. Edited in place, a step that has slipped four times looks like one that never moved.
Blocked isn't the same as slipped. If a step can't start yet, record what's blocking it and leave its date alone. Then sort slips by side: delays on your side are the ones you can fix this week.
Before each call
Every row names one person and their side
No stage, such as procurement, is still a single row
Original dates are untouched, and every move has a reason
Durations come from your own deals, with the sample size noted
You know when the buyer's budget period closes
The remaining path fits the days left, or you've said it doesn't
On signature day, write a kickoff note for delivery: why they bought, in their words, and every promise made along the way, including ones made only on a call. Carry its names and dates into a customer onboarding plan.
For a faster start, open this template with Edit with AI. River takes the buyer's process apart into steps with one owner each and dates them from the closed deals you send.
How to use this template
Use the files as they are, or open them in River. Tell River about the deal, the signature date and whatever the buyer has said about how they buy, then send dates from past closed deals, won and lost. River breaks each stage into steps with a named owner, dates them from your own history and tells you which step is holding the date.
No closed-deal dates on hand? River still builds the plan from what you know, marks anything it inferred so you can confirm it, and writes "no history" rather than inventing a duration.

Download it or open it in River
Download the three Word documents and four CSV sheets, most filled in with a sample deal, or open them in River to work with AI.
2
Share the deal and your history
Paste call notes, emails or a screenshot of their supplier portal, plus dates from your last closed deals.
3
River takes each stage apart
Procurement, security, legal and finance become separate steps, each with a named owner, a duration and what blocks it.
4
Review it with the buyer
Send the shared plan, then after each call ask River to update it and log any date that moved.

The unnamed row is the point of the sheet. Nobody at Ostara has named a contact in accounts payable, so a two-day step has no owner and cannot be scheduled. It is also the easiest thing in the plan to ask for.
Original and current sit in separate columns on purpose. The accessibility report reads overdue by twenty-one days rather than due on the eleventh.

Nine days of slack
Three of the five open dependencies are ours. That is the useful finding, because a blocker on the seller's side is an internal escalation this afternoon rather than a question for the champion.
The bottom row is the deadline behind the deadline. Ostara's capital budget closes on 26 September, so the signature date has nine days of cover rather than the thirty everybody assumed.

Thirty-five days lost and the signature date has never moved. On any plan that edits dates in place this deal reads amber at worst, because each revision erased the one before it and the slack was fictional from the start.
Sorted by side, three of the six movements are ours, and a fourth waited on our follow-ups. That makes this an operations problem rather than a qualification problem, and operations problems are fixable this week.

Common questions
What should a mutual action plan include?
A mutual action plan should include the buyer's goal and the date behind it, the people on both sides, and every step to signature. Give each step one named owner, a due date, a status and the documents it needs. Note any deadline neither side controls, such as the buyer's budget cutoff, and keep moved dates in a separate log rather than overwriting them.
What's the difference between a mutual action plan and a close plan?
A close plan is usually the seller's own list of what has to happen to win the deal. A mutual action plan is agreed with the buyer and shared with them, so it includes their internal approvals and puts names and dates on both sides. You can use both: share the plan, and keep private notes on risks and competitors in the close plan.
How many steps should a mutual action plan have?
A mutual action plan needs enough steps that each one has a single named owner. The summary you review with the buyer can stay short, but procurement, security, legal and finance each tend to hide several steps. The sample deal in this template has 17 steps in its tracker and eight in the shared summary.
What if the buyer won't fill it in?
Draft it yourself from what they've told you, then ask them to correct it. Few buyers will write a plan from scratch, but a draft that names their own approvers and budget deadline usually draws corrections, and each one makes the plan more accurate. If they won't review it at all, treat that as a warning about the deal.
What are common mutual action plan mistakes?
Common mistakes include leaving procurement or security as one line, putting a department in the owner column, dating steps from optimistic defaults, and overwriting dates when they slip. Each one hides time you'll need later. Overwriting also erases the history that shows which steps keep slipping and which side is losing the time.
Is this mutual action plan template free?
Yes. The three Word documents and four CSV sheets download free with no signup. Most come filled in with a made-up software deal, so you can see each one working before you clear it. Edit with AI opens the same files in a free River workspace.
What does Edit with AI do?
It opens the template in a free River workspace. River asks about the deal, how the buyer buys and how long steps took in your closed deals. It splits each stage into steps with named owners, dates them from your history, maps what blocks what and names the step holding the date. Nothing goes to the buyer until you send it.
