Without a loan or overdraft, the extra cash has to come from money you've already earned arriving sooner. The usual levers are deposits and stage payments, invoicing on the day the work ends with a real due date, collecting regular income by SEPA direct debit, and following up late invoices on a schedule. When your customer is a business, statutory interest and fixed compensation also apply to late payment, with no reminder needed.

The short version
- Deposits and stage payments bring money in before a job finishes.
- Invoicing on completion rather than at month end shortens the wait.
- Direct debit collects regular income on a fixed date.
- Late business invoices carry statutory interest and fixed compensation.
- None of these steps needs a loan or overdraft.
Get part of the money before the job ends
Take a shopfitting firm that fits out shops and offices, with jobs that average €3,000. If it invoices the full amount when each job is finished and the customer pays 30 days later, the firm carries the cost of materials and wages for the length of the job plus a month.
Split the same job into stages and the picture changes. A 30% deposit of €900 at booking, €1,200 when the joinery is installed and the final €900 on completion means €2,100 has arrived before the job is finished. The final €900 is all that waits on the customer's payment terms.
The deposit only helps if it's easy to pay. A payment link sent by email, SMS or WhatsApp lets the customer pay from their phone by card, Apple Pay, Google Pay or bank transfer. Through Adfin, a €900 deposit paid by bank transfer costs €2.20 to collect, because the 1% part is capped at €2 on bank transfer and direct debit; paid by standard card, it costs €9.20, as cards aren't capped. Neither method comes with a monthly fee, a setup fee or a contract.
Invoice on the day and give a date
If you invoice in a batch at the end of the month, a job finished on 6 October waits 25 days before the customer even sees the bill, and the payment clock hasn't started.
If jobs finish evenly through the month, batch invoicing adds about 15 days on average. For a firm invoicing €15,000 a month, about €7,500 more is outstanding at any time than if each invoice went out on completion (€15,000 × 15 ÷ 30). That's money earned and owed to you, freed up by changing when the invoice is sent, with no new sales.
Put a date on the invoice too, such as "due 4 December 2026", rather than only "30 days". Between businesses, if no date has been agreed at all, payment falls due 30 calendar days after the later of the customer receiving the invoice or delivery, under S.I. 580 of 2012. An agreed date gives the customer's accounts team something to schedule and gives you a clear point from which an invoice is late.
Collect regular income by direct debit
If part of your income repeats, collect it rather than waiting for it. Say the shopfitting firm also has 12 maintenance contracts at €250 a month. On SEPA direct debit, the €3,000 arrives on the collection date each month without anyone needing to remember to pay.
Each customer signs a mandate once, and you give notice before each collection, at least 14 calendar days ahead unless you've agreed a shorter period. The notice can go on the monthly invoice. With Adfin, each €250 collection costs €2.20, so the 12 contracts cost €26.40 a month to collect, and you pay only when a payment succeeds.
Follow up late invoices and use your rights
Even with stages and direct debit, some invoices are still likely to run late. A schedule that runs every time, with a reminder before the due date, one on it and firmer ones after, tends to work better than chasing whenever there's a quiet afternoon. Adfin's Essential credit control is free under a fair use policy and sends unlimited reminders by email, SMS and WhatsApp, with an aged debtors view showing who owes what and who on your side is following it up.
When the customer is a business, the law adds a cost to paying late. Suppose a €4,200 invoice is paid 40 days after its due date. Statutory interest at 10.4% a year, the rate from 1 July 2026, comes to €47.87 (€4,200 × 10.4% × 40 ÷ 365), and you're also entitled to fixed compensation of €70 because the invoice is over €1,000. That's €117.87 on top of the invoice, owed without a reminder. The rate is reset each 1 January and 1 July, and none of this applies to consumers.
ISME's survey of SME owners for Q1 2026 found 82% don't charge late payment interest. If you'd like to, without doing the sums by hand, Enhanced credit control costs 0.3% per paid invoice when used: Adfin's collection agents decide when and how to follow up within rules you approve, and statutory interest is added to overdue business invoices automatically, with grace periods and waivers for individual customers.
Common questions
What's the quickest way to improve cash flow without a loan? Start with money already owed to you, because taking deposits, invoicing on completion and following up overdue invoices on a schedule all bring in cash you've earned without new borrowing.
Can I ask business customers for a deposit in Ireland? Yes, a deposit or stage payments are commercial terms you agree with the customer before the work starts. Put them in your quote or terms so they're agreed in writing.
Does the date I send an invoice change when I get paid? Payment terms usually run from the invoice, so an invoice sent three weeks after the work ends tends to be paid about three weeks later than one sent on the day.
Can I charge interest on late invoices in Ireland? On invoices to businesses and public bodies, yes, at 10.4% a year from 1 July 2026, reset each January and July, plus fixed compensation of €40, €70 or €100. It doesn't apply to consumers.
Does direct debit help cash flow? For regular payments it does, because the money is collected on the agreed date once the customer has signed a mandate. You give notice of each collection, 14 calendar days unless agreed otherwise.
Can I add late fees to invoices for consumers? The statutory interest and compensation rules only cover business-to-business sales and sales to public bodies. Consumers are outside them.
