How to write a monthly investor update (template + the faster way)

Why you dread these (and why you shouldn't)

Let's be honest about the feeling first. It's the last working day of the month, you open a blank email to your investors, and your stomach drops a little. You're tired, the numbers are scattered across your bank app and a spreadsheet, and some quiet voice says don't put this off again. So you do put it off. Then it's two months later and you're embarrassed, which makes the next one even harder.

That cycle is the single most common reason founders stop updating their investors. Not because the news is bad — because the writing is a chore, and the numbers feel like homework you haven't done.

Here's the reframe. A monthly investor update is the cheapest, highest-return thing you can do after a raise. It's how you turn a cheque-writer into a champion — someone who introduces you to customers, flags you to other funds, and re-ups in your next round. Investors back people, and the update is how they keep believing in you between the dramatic moments. Skip it, and you go quiet exactly when you most need them in your corner.

So the goal isn't a beautiful essay. It's a short, honest, on-time note that takes you twenty minutes, not two hours.

The monthly investor update template (copy this)

Here's a structure that works for almost any UK seed-stage company. Keep it to one screen if you can. Investors skim — give them the shape they expect, in the order they expect it.

1. One-line TL;DR. Start with the headline so a busy investor gets the gist in five seconds. "Good month — revenue up 14% to £18k MRR, closed two of the three hires, runway now 9 months. One ask below."

2. The numbers that matter. Three or four, no more. For most seed companies that's: revenue (or MRR — monthly recurring revenue, the predictable income that renews each month), cash in the bank, monthly burn (what you spend over what you earn), and runway (how many months that cash lasts). Show this month versus last, so the direction is obvious. Numbers without direction are just trivia.

3. Highlights. Two or three genuine wins. A landmark customer, a product shipped, a key hire. Be specific — "signed Acme on a £2k/month plan" beats "great momentum on sales."

4. Lowlights (yes, really). One or two things that went sideways, and what you're doing about them. This is the part founders want to delete. Don't. The lowlights are what make investors trust your highlights. A founder who only ever reports good news is a founder hiding something, and experienced investors know it.

5. Key metrics / KPIs. Whatever your business lives or dies by — new customers, churn (customers leaving), pipeline, active users. Again, this month versus last.

6. The ask. End with one or two specific requests. "Anyone know a strong senior backend engineer?" "Looking for a warm intro to [target customer]." This is where your investors earn their place on the cap table. Make it easy to help.

7. Sign-off. A line of thanks and your name. Done.

That's the whole template. Seven short blocks. Notice there's nothing in there about being clever or polished — it's about being clear, honest and consistent.

The bit everyone gets stuck on: the numbers

Reread that template and you'll spot the real friction. Sections 2 and 5 — the numbers — are where the twenty-minute update turns into a two-hour one.

Because to fill them in by hand, you have to: log into your bank, eyeball the balance, find last month's update to remember what you wrote, dig out the spreadsheet where you think you tracked MRR, work out this month's burn by squinting at transactions, divide to get runway, and then second-guess all of it because you're not sure the figures are current. By the time the numbers are ready, the will to write the words has drained away.

This is the hidden tax on investor updates. The narrative is easy — you know what happened this month. It's the financials that cost you the evening. And if those financials are even slightly wrong, a sharp investor will notice, which is the exact opposite of the confidence you were trying to project.

The hard way today

If you're on Xero or a pile of spreadsheets, the monthly update looks like this. You export a report, copy the numbers across, build a little table, hand-calculate runway because the tool doesn't really do it, and hope you didn't fat-finger a figure. Every month. From scratch. And because it's manual, it's the first thing to slip when you're busy — which is always.

Some founders try to fix this with a template doc they reuse. That helps with the words, but the numbers are still a manual gather-and-retype job. The dread doesn't actually go away; it just gets a nicer font.

The faster way: the update writes itself

This is where it stops being a chore. In Ledgers, your bookkeeping is already done — your bank feed comes in via TrueLayer, transactions are categorised automatically, and everything is continuously reconciled (checked against the bank, line by line) so the numbers are always current and true. That means the financial half of your update already exists, live, the moment you need it.

So the Investor Room drafts the update for you. It pulls this month's revenue, cash, burn and runway straight from your live ledger — the real figures, not a stale export — and assembles them into the same clean structure as the template above, with this-month-versus-last already worked out. Runway and burn are calculated for you. Plan-vs-actual, if you set targets at the raise, slots in so investors can see whether you're tracking. The numbers section, the part that used to eat your evening, is simply there.

Your job shrinks to the part only you can do: the human bit. You add the highlights, the honest lowlight, and the ask, in your own voice. Then you send. Twenty minutes becomes five, and "on time, every month" becomes the easy default rather than the heroic exception.

What you'd actually see and do

You open the Investor Room on the first of the month. The draft is waiting. The TL;DR has the headline numbers filled in. The metrics table is populated and correct, with arrows showing direction. You type three highlights, one lowlight and an ask. You read it once, nod, and share it — either as an email or as a scoped Investor Room link where each investor sees a tidy "since you last visited" view of progress.

No exporting. No retyping. No quiet fear that a number is wrong. Just an honest update, out on time, building the trust that gets you re-upped next round.

The short version

A good monthly investor update is short, honest and consistent: a one-line TL;DR, the four numbers that matter, highlights, real lowlights, your KPIs, and a specific ask. The words are easy. The numbers are what make it a chore — so let them write themselves, and spend your twenty minutes on the part that's actually you.

Frequently asked questions

What should a monthly investor update include?

A one-line summary, your key financials (revenue, cash, burn, runway), two or three highlights, one or two honest lowlights, your core metrics versus last month, and a specific ask. Keep it to roughly one screen.

How long should an investor update be?

Short. Aim for something an investor can read in two or three minutes — roughly one screen. They'll skim it regardless, so clarity beats length every time.

Should I include bad news in an investor update?

Yes. A short, honest lowlight with your plan to fix it builds far more trust than an all-good-news update. Experienced investors are wary of founders who only ever report wins.

How often should I send investor updates?

Monthly is the standard for seed-stage companies, sent within the first few days of the new month. Consistency matters more than perfection — a plain update on time beats a polished one that never arrives.
