Profitable on Paper, Broke in the Bank: 11 Levers to Free Up Cash in Your Business
Most business owners who contact us about cash flow don't have a profit problem. They have a timing problem which impacts a thing called "working capital". Working capital is the money tied up in simply running your business day to day: what customers owe you, plus what's sitting in stock, minus what you owe suppliers.
Every dollar of it is money you've already committed that hasn't come back yet. The problem is timing. If stock sits for 45 days, customers take 50 days to pay, and you pay suppliers in 30, you're out of pocket for roughly 65 days on every sale and that gap has to be funded by something: cash reserves, an overdraft, or the owner not taking a wage.
Two things follow, and they catch people out. First, growth makes it worse before it makes it better — double your sales and you double your debtors and your stock, which is how profitable, fast-growing businesses can quickly run out of money.
Second, and more usefully: you don't necessarily need more sales to free up cash, you need a shorter gap . Collect five days faster, hold a week less stock, pay suppliers ten days later, and you've released real money without winning a single new customer. That's what the rest of this article is about; eleven practical ways to shorten the gap, roughly in order of how quickly they work.
At the end of the day, cash is king because it pays the bills (not profit).
Money in, faster
1. Shorten the gap between doing the work and asking to be paid
The most common cash leak we see isn't slow payers — it's slow invoicing. Work is finished on the 3rd, invoiced on the 30th, and the client's payment terms only start from there. On the 20th-of-the-month-following terms that are still common in New Zealand, that single delay can cost you seven weeks.
Invoice on completion, or better, on milestones. If you bill monthly in arrears, ask whether you could bill fortnightly, or in advance. For project work, a deposit of 30–50% is standard in most sectors — you may be the only one in your industry not asking for one.
If you're in construction, look hard at retentions. Money withheld against your work is your money, and under the Construction Contracts Act retentions must be held on trust and released once your obligations are met. Track them, diary them, and chase them like any other debtor. Most subcontractors don't, and it's often the single largest sum of cash they can't see.
2. Make paying you effortless — and get on eInvoicing
Every bit of friction adds days. Put a payment link on the invoice. Take card and Account2Account payments. Set up direct debit for recurring clients. Check the invoice actually carries the right purchase order number, contact name and email address — a surprising share of "late" invoices are simply sitting in the wrong inbox.
If you sell to government, eInvoicing through the Peppol network is now one of the fastest cash wins available. Under the Government Procurement Rules that took effect in January 2026, mandated agencies must pay 95% of domestic eInvoices within five business days, and other domestic trade invoices within ten. That's a structured invoice landing straight in the agency's system rather than a PDF being rekeyed by someone in accounts.
Worth knowing: New Zealand and Australia run a joint approach to eInvoicing on the same Peppol standard, so if you trade both sides of the Tasman, one setup covers you.
3. Build a credit control rhythm, not a confrontation
Chasing shouldn't be an emotional event that happens when you're panicking about wages. It should be a boring, scheduled process:
Three days before due: a friendly "just confirming this is approved for payment"
Day after due: polite reminder
Day 7: phone call
Day 14: escalation to a named person, with terms restated
Businesses that chase on a calendar get paid materially faster than businesses that chase on a feeling. And that first call isn't chasing at all, it's confirming the invoice cleared approval, which is more often than not where most delays actually happen.
4. Rank your customers by days-to-pay, not revenue
Pull your top 20 customers and sort them by how long they take to pay. There's usually one that's large, well-known, and quietly funding its working capital out of yours. Either reprice to reflect the cost of that credit, shift them to deposits or progress claims, or let them go. Revenue collected in 90 days is worth materially less than revenue collected in 14 days.
(Across the Tasman, Australia's Payment Times Reporting Scheme publishes how quickly large businesses pay their small suppliers. If you're weighing up a big Australian customer, it's a free due diligence check worth doing before you extend them terms.)
Money out, slower
5. Negotiate supplier terms before you need to
Ask your three largest suppliers for extended terms while your payment record is spotless — not once you're already struggling. Suppliers extend credit to reliable customers and tighten it on distressed ones. The best time to ask is when you don't need it.
The aim is to close the gap between paying suppliers and being paid by customers. If you pay in 30 and collect in 60, you are financing your own growth out of the bank account. Narrow that gap and growth starts funding itself.
6. Stop paying early for no reason
Plenty of businesses pay every bill the day it lands, out of habit or tidiness. Unless there's an early settlement discount that beats your cost of capital, pay on the due date. Run one or two supplier payment runs a month instead of paying daily — you get predictability as well as float.
Cash already trapped inside the business
7. Attack the stockroom
Inventory is cash in a cardboard box. Pull an aged stock report and be honest about what's genuinely slow-moving versus what's dead. Discount it, bundle it, or write it off and clear the space — recovering 40% today usually beats 100% of a sale that never comes.
Then look at your reorder quantities. Buying twelve months of a component to secure a 5% bulk discount is a poor trade if it costs you eleven months of tied-up cash — particularly with shipping lead times into New Zealand being what they are.
8. Question every asset you own
This area is one of my favourites because there is opportunity to look at business differently. Do you need to own the utes, the machinery, the plant? Asset finance, leasing and sale-and-leaseback all convert a lump of capital into a monthly cost. That isn't always the right answer — it costs more over the life of the asset — but when cash is the binding constraint, spreading the cost is often worth the premium.
While you're there, audit the subscriptions. Most businesses we review are paying for software seats belonging to people who left, duplicate tools across departments, and annual renewals nobody has looked at since signing.
The tax levers most businesses underuse
This is where New Zealand businesses leave the most cash on the table — usually not by paying the wrong amount of tax, but by paying it at the wrong time.
9. Check you're on the right GST basis and frequency
If your taxable supplies are $2 million or less, you can apply to account for GST on the payments basis — meaning you return GST when you actually receive the money, not when you issue the invoice. For any business carrying meaningful debtors, that's the difference between funding IRD's cash flow and funding your own. The trade-off is that you can't claim input tax until you've paid your suppliers, so it's worth modelling rather than assuming.
Filing frequency matters too. Six-monthly filing is available under $500,000 of turnover and lets you hold GST longer. Conversely, if you're consistently in a refund position — exporters zero-rating sales, or businesses in a heavy investment year — monthly filing gets that cash back sooner. The right answer depends entirely on which side of the ledger you sit.
(Australian readers: the equivalent lever is cash-basis GST reporting, available at an aggregated turnover under $10 million — a far more generous threshold than ours.)
10. Take control of provisional tax
Provisional tax catches out more otherwise-healthy New Zealand businesses than almost anything else, because it's calculated on last year rather than this one. Three options are worth a conversation:
AIM (the Accounting Income Method) — available to businesses with gross income under $5 million, calculated by your accounting software on actual profit as you earn it. If your income is seasonal, lumpy, or growing fast, you pay when you've made money rather than when a formula says you should.
The GST ratio option — aligns provisional tax with your actual GST-taxable supplies, which suits declining or seasonal income.
Tax pooling — through an IRD-approved intermediary such as Tax Management NZ or Tax Traders, you can defer a provisional tax instalment to a date that suits your cash flow, paying interest to the pool instead of use-of-money interest and late payment penalties to IRD. The interest is deductible. For a business facing a large instalment three weeks before a big receipt lands, it's often the cheapest bridging finance available.
If you already have tax debt, talk to IRD about an instalment arrangement before penalties compound. They're considerably more receptive to a business that comes to them early with a forecast than one that goes quiet.
11. Claim the reliefs you're entitled to
Investment Boost. Since 22 May 2025, businesses can claim an immediate 20% deduction on the cost of new (or new-to-New Zealand) business assets, on top of normal depreciation. There's no cap and no application process. For new commercial and industrial buildings (which otherwise depreciate at 0%) this is a deduction that simply didn't exist before.
The low-value asset write-off. Assets costing $1,000 or less can generally be deducted in full immediately. Note you can't use this and Investment Boost on the same asset.
The R&D Tax Incentive. A 15% credit on eligible R&D spend, refundable in cash in some circumstances, with a $50,000 minimum annual spend to qualify. Loss-making R&D businesses may also access the R&D loss tax credit at 28%, and the two together can be worth up to roughly $43 in cash support for every $100 of eligible spend. Approval deadlines are strict, so this needs planning rather than a scramble at year end.
Two things worth flagging: Investment Boost expenditure is itself eligible for the RDTI, so the two stack. And Budget 2026 has proposed administrative changes to the RDTI including quarterly in-year payments to help cash flow — worth watching if you're an R&D-intensive business.
(For context, Australia's R&D Tax Incentive is noticeably more generous — a 43.5% refundable offset for companies under A$20 million aggregated turnover. If you operate on both sides, where your R&D is physically performed has real cash consequences.)
The thing that makes all eleven work
None of the above matters much if you can't see the problem coming.
A rolling 13-week cash flow forecast that is updated weekly, built on actual expected receipts and payments rather than the P&L — is the single most valuable management tool a small business can have. It turns "I think we'll be alright" into "we're $22,000 short in week six unless the payment for the invoice lands from Customer A and the provisional tax instalment gets pooled." That's the difference between a decision made calmly six weeks out and a decision made in a panic on a Wednesday night.
It also transforms your relationship with lenders. Arranging an overdraft or debtor finance facility when you can evidence a forecast is straightforward. Arranging one when you're already short is expensive, if it's possible at all.
Start here this week
If you do nothing else:
Pull every unpaid invoice over 30 days old and make three phone calls
Check whether you're eligible for the GST payments basis and whether it would help
Ask one supplier for longer terms
Cancel or amend three subscriptions where you’re not getting value
Build a 13-week forecast, even a rough one in a spreadsheet
That's usually a few weeks of breathing room, earned in an afternoon.
At O&U Group, we work with business owners to turn cash flow from a monthly source of stress into something predictable and managed. If your business is profitable on paper but tight in the bank, that gap is fixable and it's usually much smaller than it feels.
