What should an in-house finance team use for week-to-week cash, when the accounting software holds the record and a planning tool holds the budget? It needs a weekly view of the cash it holds, the cash it expects to receive and the payments it has to make over the coming weeks, kept current as those dates move. Accounting software records what has happened. Planning tools hold the budget and the longer-range plan. A treasury management system handles payments, funding and financial risk at scale. The weekly cash work sits between accounting software and a treasury management system, and we call it the operational cash layer.
This guide is for finance directors and finance managers in teams of three to eight, in businesses with several entities, bank accounts or currencies and no treasurer. Your ledger records an invoice on the day you raise it. It does not record the day the customer will pay. A budget says what you planned to spend. Neither tells you which week the money will arrive. Someone in the finance team has to hold the current answer to one question: what cash will the business have in each of the next 13 weeks? They have to keep that answer up to date as customers pay late and plans change. That job is the operational cash layer.
Why The Gap Appears At This Size
In a small business the gap is hard to see. With one company and one bank account, the cash position can be read from the bank, and the ledger with a monthly check is enough.
The gap opens as the business grows into a finance team of three to eight. Nothing is wrong with the ledger. It shows what you are owed and what you owe today. It holds no forecast of when each unpaid invoice will be settled, and that date moves. A customer due to pay on the 30th says the payment will come three weeks later. A supplier payment slips into the next week. A hire is brought forward. Together these decide whether the balance holds in the week payroll leaves. Our guide to cash flow forecasting and accounting reports explains why the ledger cannot answer this.
Official figures show how far payment dates drift from agreed terms. In the UK, the median large business reported paying 15% of its invoices, by number, after the agreed terms in 2025, according to the Department for Business and Trade's payment practices statistics. In Australia, large businesses had an average paid-on-time rate of 68.5% on invoices from small-business suppliers in the second half of 2025. The average common payment term was 29 days, and it took 55 days to reach 95% of those invoices paid, according to the Payment Times Reporting Regulator.
Three signals show that a finance team has reached this point.
Several entities, bank accounts or currencies. Cash is no longer visible in one place. Someone has to add up balances from separate ledgers and accounts before any question can be answered.
Payment timing and weekly reporting demands. The leadership team asks about cash every week. A month-end report describes a date that has already passed.
Short-term liquidity risk. A tight week has to be seen while there is still time to move a payment or chase a receipt.
Professional bodies treat this as treasury work, and it does not go away when a business has no treasurer. The Association of Corporate Treasurers says that in a small business "staff in the finance team will carry out specific treasury activities as part of their day-to-day responsibilities". A 2017 guide from the Chartered Institute of Management Accountants and the same association adds that many smaller organisations will not need a treasury management system, because their treasury operations are relatively simple and involve low volumes. So the work sits with the finance team, and the system built for treasurers is more than the team needs.
Where that work lives in a spreadsheet one person rebuilds each week, the forecast depends on that person. The planner built into accounting software covers the near term for a single company, and our comparison of built-in planners and dedicated forecasting tools sets out where that stops.
What Each Layer Is For
A finance team answers four different questions about money, and each has a layer of its own. No accounting or treasury body describes finance as a stack, and in practice the four overlap.
| Layer | The question it answers | Typical horizon | Who does the work at this size |
|---|---|---|---|
| Accounting software | What has happened, and what do we own and owe? | Transactions as they are recorded, and the position today | The finance team, with the external accountant at year end |
| The operational cash layer | What cash will we have each week, and what do we do about it? | The weeks ahead. This page uses a rolling 13 weeks, reviewed every week | The finance manager or controller, with the finance director |
| Financial planning and analysis (FP&A) | What is the plan, and are we on it? | The coming quarter and year, and longer-range plans | The finance director or CFO, reporting to management and the board |
| Treasury management system | How do we control payments, bank accounts, funding and financial risk at scale? | From today's cash to long-term funding | A treasurer or treasury team in a larger business |
The last column describes a finance team of three to eight people. The Association for Financial Professionals defines FP&A as the function within the office of the CFO that supports strategic decisions through integrated planning, budgeting and forecasting, performance management and financial analysis. It describes a treasury management system as "an enterprise-wide solution".
A business does not need all four at once. Each is added when its question starts being asked and nobody can answer it. The treasury boundary has a guide of its own: our guide to a treasury management system against a cash forecasting tool.
What The Operational Cash Layer Does Each Week
Five jobs make up the layer, and each one is established practice. What changes is that they sit together, in one place, on a weekly rhythm.
One cash position across accounts and entities. Every bank account and every company is brought into a single opening figure the whole team works from, with the detail kept underneath. A group total does not mean every balance can be moved freely between companies.
A rolling 13-week view. Thirteen weeks is one quarter. An article on the Association of Corporate Treasurers' knowledge hub describes operational cash forecasts as short term, generally covering the next 13 weeks on a rolling basis. Thirteen is a convention. Some teams work to a shorter window. The early weeks rest on receivables and payables already in the ledger, and the later weeks rest more on budgets.
Expected dates on receivables and payables. The due date says when an invoice should be paid. The expected date says when the team believes it will be paid. The forecast runs on the second. ICAEW's guidance for finance professionals puts it as assigning expected, worst case and best-case dates for receipts and payments. Our guide to keeping a cash forecast up to date shows how those dates are kept current week to week.
What-if scenarios. A late customer, a delayed hire or a large purchase is tested against the base forecast before the decision is made, and the base stays as it was.
A weekly report for the leadership team. The same view goes to the CEO and the finance director every week, so the business discusses one set of numbers. Weekly is the right rhythm. The same ICAEW guidance says cash meetings should be weekly at minimum when conditions are uncertain.
How Float Does This Today
Float is cash flow forecasting software for in-house finance teams. It gives the team one place to run the five jobs, built on the ledger they already keep. Float connects to Xero and QuickBooks Online today, with Sage Intacct coming soon; you can join the Sage Intacct waitlist. Much of the routine work runs without anyone touching it: the daily sync, actual figures replacing budgets as they land, linked budgets moving with their source and, for Xero users, expected dates set from each customer's and supplier's payment history.
The cash position. Float reads ledger data from your accounting system through a one-way sync. The sync runs once a day at an hour you choose, and you can run a manual sync on demand. Float never writes back to your accounting system. The starting balance is the reconciled ledger balance of the bank accounts you include, so the forecast starts from figures the team has already agreed. Where a group has several companies, Float consolidates them at company level into one view, in a display currency you choose.
The 13-week view. Float builds a weekly cash forecast for the next 13 weeks on that ledger data, with a monthly view alongside it for longer-range planning. Budgets are placeholders for the cash you expect. As invoices, bills and transactions land, the actual figures replace them. A budget can be linked to another, so a cost set as a percentage of sales moves when the sales budget moves, with an offset where the cash leaves later.
Expected dates. You can move the expected payment date on any invoice or bill in Float. For Xero users, Smart Expected Dates goes further. Float works out how many days after the due date each customer and supplier typically pays, from your own payment history, and applies that average to new invoices and bills as they arrive. You can override any date. It runs on Xero-connected companies; on other connections, expected dates are moved by hand.
Scenarios. What-if questions go into scenario layers that sit on top of the base forecast. A scenario changes budgets only, and when a decision is made its budgets can be moved into the base.
The weekly report. You export the forecast as a PDF or a CSV when you need it, or show it on screen in presentation mode. Float shows the date on which the balance is due to cross a threshold you set. The team can comment on an invoice, a bill or a budget line, so the reason for a change stays with the number. User roles include a read-only viewer for the CEO or the board.
What Changes For The Finance Team
The first thing to go is the weekly rebuild. The forecast takes its figures from the ledger each day, so the weekly cash meeting starts from the current position and the team spends its time on what changed. The group also has one cash figure. The finance manager, the finance director and the CEO read the same view, and nobody has to ask which version is current.
A tight week is seen earlier. The team sets a cash threshold, and Float shows the date the balance is due to cross it, which leaves time to chase a receipt or move a payment. Decisions get tested before they are made. A hire or a purchase is laid over the base forecast as a scenario, and the meeting looks at both lines.
Take an invented example. A finance manager wants to bring a hire forward from January to October. In a scenario, the salary and on-costs start in week three. The base forecast stays above the team's £150,000 cash threshold in every week. With the hire, week nine dips to £138,000, because a quarterly tax payment lands in the same week. The meeting moves the start date back by four weeks, and the balance holds. The decision takes one meeting, and the CEO sees the same two lines the finance team does. Our guide to reading a hire decision on a cash forecast works through the full arithmetic.
Stefan Wallington, CFO at Networkology, describes the result this way: "It has become an invaluable part of our finance toolkit, giving us confidence in our planning, improving visibility across the leadership team, and helping us stay ahead of potential challenges rather than reacting to them."
How To Set This Up In Float
Step 1: Connect your accounting software. You authorise Float to read your accounting ledger. Float imports the previous three months of actuals, along with the current and future months.
Step 2: Review the suggested income and costs. Float proposes regular income and costs from your history, and you choose which to apply. Link costs that move with sales to the sales budget, and add budgets for cash that is not in the ledger yet.
Step 3: Set up the expected dates. On Xero, turn on Smart Expected Dates for invoices and bills, so new ones take each customer's and supplier's usual payment timing. Then check your largest unpaid invoices and bills and override any date you know to be wrong.
Step 4: Set a cash threshold. Choose the balance you do not want to fall below. Float shows the date the forecast crosses it.
Step 5: Add your other companies. Connect each company, then build a consolidated view and choose the display currency.
Step 6: Invite the team. Give each person edit or read-only access, and take the 13-week view to your next weekly cash meeting.
Where This Is Going
A rolling cash forecast is not new. What is still done by hand is the checking around it. Float's view is that the operational cash layer should become a cash system the team runs, one that keeps reconciling what was expected with what happened, reassesses what is likely to happen next, and shows where attention is needed. That depends on a richer record of how cash moves through a business, including when customers pay, when suppliers are paid, and how forecasts differ from actuals. That record should connect outstanding customer invoices and supplier bills with bank balances and available liquidity, and carry the context that explains each movement, which today often lives outside the ledger. Float sets one condition on that direction. The numbers have to stay traceable to their source and under the finance team's control.
The automation described above, from the daily sync to expected dates set from payment history, is where that path starts: each piece takes routine work off the team while the numbers stay traceable to the ledger.
When A Business Needs A Different Layer
The operational cash layer has edges, and it helps to know them before a buying conversation.
If you need a profit and loss forecast, a balance sheet forecast and a cash flow forecast that reconcile to each other, that is an integrated three-statement forecast, often called three-way forecasting. It sits with planning software, along with full budgeting. Float does not do it, and the reasoning is in our piece on why Float forecasts cash and not the P&L.
If you need to make and authorise payments from one system, or manage currency and interest-rate risk, those are the jobs a treasury management system is built for, usually through direct connections to the banks. Float is not built for payments or hedging. A treasury management system also forecasts and positions cash as one of its functions, so a business large enough to run one may find it covers this layer as well.
Frequently Asked Questions
We use Xero for accounting and a planning tool for budgets, what should we use for week-to-week cash?
For week-to-week cash, use a tool in the operational cash layer: one that reads your Xero ledger and holds a rolling 13-week cash forecast with expected dates on invoices and bills. Xero holds the record and your planning tool the budget. Neither tracks which week cash will arrive. Float does this job for in-house finance teams.
What sits between accounting software and a treasury management system for managing cash?
The operational cash layer sits between accounting software and a treasury management system. It is the weekly job of holding one cash position across accounts and entities, a rolling 13-week view, expected payment dates, what-if scenarios and a report for the leadership team. Accounting software keeps the record; a treasury management system handles payments, funding and financial risk at scale.
Is short-term cash forecasting a treasury job?
Yes, professional bodies place short-term cash forecasting inside treasury. The Association of Corporate Treasurers says that in a small business the finance team carries out treasury activities as part of its day-to-day work. The operational cash layer is our name for that work when it is done without a treasurer or a treasury management system.
Do we need a treasury management system if we have no treasurer?
It depends on the work you need done. A treasury management system is built for payments, bank connections, funding and financial risk at scale, and smaller organisations with simple, low-volume treasury operations often do not need one. If your question is what cash you will have each week for the next quarter, that is the operational cash layer's job.
Does Float change anything in your accounting system?
No, Float changes nothing in your accounting system. The sync runs one way: Float reads ledger data once a day at an hour you choose, or when you run a manual sync, and it never writes back to your accounting system. Inside Float, each person gets edit or read-only access.
Float is built for in-house finance teams of three or more that run cash across several companies, bank accounts or currencies. If your weekly cash job lives in one person's spreadsheet, the next step is a conversation with the Float team.
