Monthly Investor Update Financials Template
Your close package becomes the investor metrics with a definitions note behind them, so a number that moves means the business moved.
River takes the closing package and produces two files: the metrics sheet investors read, and the one-page note stating exactly how each number was built. Formula, source system, what sits inside it, what is deliberately outside it, and the date the definition last moved. The sheet runs the current month against the prior month and the same month a year ago, so a reader sees the trend without rebuilding a single figure of it themselves.
Annual recurring revenue has at least five defensible definitions and each produces a different number from the same ledger. The regulator expects a filer changing how a metric is calculated to disclose the difference, the reason, the effect on what was previously reported, and whether prior periods were recast. Your data room gets held to that standard by an analyst with a spreadsheet and no obligation to be generous. A definitions note written in advance is the cheapest insurance in the whole update.
Written for the founder or finance lead sending a monthly update, and for the controller who has to defend those same numbers eighteen months later. The inputs come straight out of the monthly close pack. The variance explanation is the one already going to the board in flux commentary, and the runway line reconciles to the 13 week cash forecast. Fund managers writing to their own investors want the quarterly LP letter instead.
Five readings of ARR, one subledger
Take one month's closing subledger at a company doing roughly nine million. Count contracted subscription net of customers who have served notice and you get 9,020,400. Add the month-to-month accounts and it is 10,255,200. Add usage overage and services retainers and it is 11,001,600, twenty two percent above where you started. Every one of those is defensible, none of them is wrong, and an update that never says which one it used has said nothing at all.
The damage is not the definition, it is the change. A metric that quietly picks up overage in February shows twenty five percent growth in a month when customers grew three point six. The staff's own interpretation holds that a measure presented inconsistently between periods is misleading unless the change is disclosed and the reason for it explained, and prior measures are often recast. The note records every change with its date, and the sheet restates the months behind it.
Each row of the note carries six things: the metric, the formula written out, the system the inputs come from, what is included, what is excluded and why, and when the definition last moved. Exclusions do most of the work. Free trials are not customers, design partners paying nothing are not logos, a signed contract that starts in May is not April revenue. Writing those down once ends the argument permanently, and it is the row diligence reads first.
How it works
Add the close package
Drop in the month's financials, the billing subledger and the update you sent last month.
Name your metrics
Say which numbers investors already expect from you and which ones you want to add.
River writes both files
Definitions first, then the metrics computed against them, with prior periods restated where needed.
Send and reuse
Next month starts from this month's note, so the definitions hold unless you change them.
What you get
- A definitions note carrying formula, source, inclusions, exclusions and the date each last changed
- Current month against prior month and the same month last year on every line
- Every definition change logged with its effect on the numbers you already reported
- Prior months recast whenever a definition moves, so the trend stays comparable
- Exclusions stated explicitly, since free trials and design partners are where counts drift
- Every figure traced to the close package, so diligence reconciles it in minutes
Common questions
Why is the definitions page the important half?
Because the metrics are only as good as the agreement about what they mean, and that agreement is the thing nobody writes down. An investor comparing your April deck to your November deck is checking whether the same question got the same treatment. The note answers that in one page, permanently.
I have already been reporting a metric loosely. What now?
You write the definition you are going to use from here, restate the prior months onto it, and show both series once. That is a stronger position than it feels like: a founder who volunteers a restatement reads as someone with controls. A founder whose numbers get restated for them in diligence reads as the opposite.
Which metrics does it handle?
The standard set covering recurring revenue, retention, gross margin, burn, runway, customer counts and acquisition payback, plus whatever your model actually runs on. Marketplaces get take rate and gross merchandise value, usage businesses get consumption per account, services businesses get utilisation. You name them and each one gets a definition row. Acquisition payback gets built cohort by cohort in the unit economics pack.
Where do the numbers come from?
The close package and the billing subledger you upload, with every figure traced back to a source so an analyst can reconcile it. Nothing is estimated to make a trend look better. Where the ledger cannot support a metric you asked for, River says so and tells you what input it needs instead.
Does it write the narrative around the numbers?
It writes the metrics, the definitions note and the short commentary explaining each material move. The personal parts of an update, the asks, the hiring, the customer stories, stay yours. The same variance analysis already feeding flux commentary drives the explanations here, and the questions those numbers will attract come out of the board question prep brief.
What happens the month I change a definition?
River logs the change with its date, computes the effect on the numbers you already published, restates every prior month onto the new basis, and drafts the two sentences telling investors what moved and why. The old definition stays on the note with an end date rather than disappearing from the record.
Does this only apply to venture-backed companies?
Any business reporting numbers to people outside it gets the same benefit. Lenders reading a monthly certificate care intensely about consistent definitions, which is the same problem approached from the credit side through the covenant definition extractor. Family shareholders and prospective buyers ask identical questions.
