Spreadsheet Multiplier - Six-week live cohort - £695
Build forecast models your finance team can run without you
Create a clear, auditable forecast model. Add controls, checks and documented assumptions. Then train colleagues to update it safely, so month-end does not stall when you are away.
Build models your team can run without you
Finish the six weeks with a reliable forecast, a safer handover process and fewer spreadsheet emergencies landing back on your desk.
Get your analysis time back
Spend fewer hours repairing broken formulas, explaining basic updates and rebuilding reports. Use that time to investigate variances, challenge assumptions and advise the business.
Trust the numbers before they reach the board
Build in visible checks, controlled inputs and clear calculation flows. Catch errors earlier and review forecasts without hunting through mystery tabs and hidden formulas.
Let colleagues update models safely
Hand over routine reporting and forecasting tasks with clear instructions and sensible guardrails. Your team can make updates without turning every change into a support ticket.
Keep month-end moving when you are away
Create workbooks that another accountant can follow, check and complete. Holidays and sick days stop being a single-point-of-failure test for the finance function.
Produce a forecast the business can use
Leave with a working model that makes assumptions clear and shows what drives the result. Update scenarios faster and give decision-makers answers they can act on.
Teach the method, not every mouse click
Use a repeatable way to explain model logic, checks and ownership. Build capability across the team without becoming permanent spreadsheet support.
What changes when the whole team can use the model
I rebuilt our 13-week cash flow forecast during the course and handed the weekly update to our assistant accountant. She now completes it in 25 minutes, checks included. I review the movements instead of repairing formulas.
Month-end used to pause if I took a day off because nobody wanted to touch the reporting workbook. After adding clear inputs, control totals and a one-page handover, my management accountant ran the pack without me. Nothing broke. I even kept my phone off.
The big win was stopping the same forecast questions every Friday. I used the teaching method from Spreadsheet Multiplier to train two colleagues in one session. Support messages dropped from around 15 a week to two.
Built for the accountant everyone asks to fix the spreadsheet
Income Octopus exists because being the safest pair of spreadsheet hands should not mean owning every workbook forever. Founder Rachel Morgan spent 14 years in management accounting and financial control. She saw the same pattern in growing finance teams: one person built the forecasts, repaired the formulas and answered every nervous question at month-end. Spreadsheet Multiplier turns that hard-won experience into a six-week, live course. You build a working forecast model, add checks that catch errors, document assumptions and practise handing the model to someone else. No abstract exercises. No clever formulas added for sport. Every method is designed around the work small finance teams actually do. That means messy source data, changing assumptions, tight reporting deadlines and colleagues with mixed spreadsheet skills. You leave with a model your team can update safely and a repeatable way to train them, so annual leave stops being a business continuity risk.
Six weeks to build a forecast your team can run without you

Questions before you commit
Is Spreadsheet Multiplier worth £695 if I already know Excel?
This is not an Excel basics course. It is for accountants who can already build a forecast but keep becoming the only person trusted to maintain it. You will build a working forecast model, add practical checks and controls, document assumptions, and create a handover process your team can follow. The return is fewer repair jobs, faster updates, and less key-person risk at month-end.
How much time will I need each week?
Allow around three hours a week for six weeks: one live session plus focused build time. You will work on a forecast model during the course, so the practice produces something useful rather than another abandoned training exercise. Dates and deadlines are set before the cohort starts, making it easier to plan around month-end.
What if month-end clashes with a live session?
You will receive the session recording and supporting materials, so one busy close does not derail the course. You can catch up before the next session and bring questions to the following live class. The course is designed for working finance teams, not people with suspiciously empty calendars.
Will this work with the spreadsheets we use in our business?
Yes, if you use spreadsheets for management reporting, forecasting or month-end. The method is built around common finance problems: unclear inputs, hidden assumptions, fragile formulas, missing checks and handovers that rely on memory. You can apply the approach whether your source data comes from Xero, Sage, QuickBooks, NetSuite or exported CSV files.
Am I experienced enough for the course?
You should be comfortable with formulas, linked sheets and basic forecast logic. You do not need VBA, Power Query or advanced coding skills. If colleagues already send you the difficult workbook because you are the safest pair of hands, you are likely at the right level.
Will it still help if my colleagues are not strong spreadsheet users?
That is the point. You will learn to make models easier to update safely, with clear input areas, visible assumptions, checks, instructions and defined ownership. You will also use a repeatable method for teaching colleagues without turning every handover into unlimited helpdesk cover.
Can my employer pay for it?
Yes. The £695 fee can be invoiced to your employer. The business case is straightforward: reduce reliance on one modeller, improve forecast continuity, cut time spent fixing avoidable errors, and make reporting work easier to review. You will also leave with a working model and a handover method the wider finance team can use.
Is this relevant if our existing workbooks are already complicated?
Yes. You do not need to rebuild every workbook from scratch during the six weeks. You will learn how to identify the highest-risk parts, separate inputs from calculations and outputs, add proportionate controls, and document the logic. The aim is a model another competent accountant can follow, not a beautiful spreadsheet only its creator understands.
Your finance team should not stop when you take a week off
Join Spreadsheet Multiplier and spend six weeks turning your modelling know-how into clear, checked workbooks your colleagues can update safely. Fewer formula rescues. More time to explain what the numbers mean.
