We help businesses forecast their short-term cashflows
Why we're here
13WEEKS helps businesses build 13 week cashflow forecasts so they can effectively manage their liquidity.
In our experience, many companies don't implement a 13 week cashflow forecast until they start facing liquidity issues. At that point, the work is typically rushed and requires expensive consulting support just to build basic visibility.
We also see companies turn to third-party software solutions as a way to "outsource" the forecasting build - without fully appreciating the implementation challenges and costs involved.
That's why we created 13WEEKS: to be your first stop in the cashflow forecasting journey. We've developed a comprehensive suite of training materials and templates to help you build a 13 week cashflow forecast for ANY business. And with our one-to-one consulting support, we can make sure the forecast you build is right for your organisation.
Our cost-effective services are designed to help you learn quickly, build fast, and iterate. We believe it’s far better to develop the capability in-house so you can truly own your short-term cashflow forecasting. Once you’re up and running, you’ll be in a position to decide — based on experience — whether a more advanced software solution is worth it.
Core beliefs
Our services to you are grounded in the following core beliefs:
-
There is no one-size-fits-all solution: We often hear clients asking for a “plug-and-play” approach, but in reality this doesn’t exist. Every company is different. Standard templates can help you get started, but the real value comes from adapting the forecast to reflect the unique characteristics of your business.
-
Software platforms are not a silver bullet: There are several 13 week cashflow forecasting platforms in the market, and many of them are excellent. However, like any new IT system, they often require a significant investment of time, money, and internal resource before you can use them effectively. You will still need to tailor the tool to your business – and risk spending heavily on something that ultimately isn’t a good fit.
-
Start simple, move fast: We believe in the concept of the minimum viable product (MVP). Rather than embarking on a long, expensive project, it’s better to start with something simple, test it quickly, and then iterate and improve based on what you learn.
Experience to help you achieve results
We have over 10 years’ experience helping clients build and improve their cashflow forecasts and optimise their working capital performance. We’ve taken everything we’ve learned and packaged it into a practical, easy-to-use resource so that any company can build a cashflow forecast for their business.
And yes — we’re giving away ALL our secrets.
Our platform walks you through the entire process of building a 13 week cashflow forecast, step by step, from scratch. You won’t just learn the technical aspects of cashflow forecasting — you’ll also develop the Excel modelling skills you need to build an effective forecast in ANY business situation.
Go fast, build, iterate
Our CashflowFree package gives you everything you need — a downloadable workbook, step-by-step training video, and a PDF user guide — to build your first 13-week cashflow forecast in less than 24 hours.
For companies that need something more sophisticated, our CashflowPlus+ and CashflowPro options include additional modelling tools and guidance designed to help you develop a robust first draft within 1–2 weeks.
What makes our approach different is that it empowers you to take control of the process. Instead of jumping straight into a costly consulting engagement or committing to a long and expensive software implementation, you can build a working model in-house and use it as a testbed. Iterate, refine, test again — and only once you truly understand what “good” looks like for your business do you move on to something more advanced.
This way, you win either way:
-
If the in-house model continues to meet your needs, you’ve avoided unnecessary spend and developed internal capability along the way.
-
If you reach the point where a specialist system is required, you’ll already know exactly what you want — and have aligned stakeholders — making the software implementation faster, cheaper, and far more effective.
Learning designed for busy professionals
We know that building a cashflow forecast takes commitment — but it shouldn’t require dropping everything else. That’s why we’ve broken our content into short, bite-sized modules, with an average video length of just 7 minutes. You can work through the materials at your own pace, fitting them around your full-time job without feeling overwhelmed.
Unlike classroom-style training, which often requires 1–3 full days (and is quickly forgotten the moment you walk out the door), our training is available on-demand. You can go back and rewatch the videos as many times as you want, whenever you need a refresher or want to revisit a specific topic.
In short: yes, it requires commitment — but we’ve structured everything so that commitment feels achievable and leads to real, lasting results.
