How Invoice Financing Works: A Step-by-Step Guide for Singapore SMEs

If your business issues invoices with 30, 60, or 90-day payment terms, you already know the frustration: the work is done, the invoice is sent, and the cash still doesn't arrive for months. Invoice financing (also called receivables financing or factoring) solves this specific problem — turning an unpaid invoice into usable cash within days instead of waiting out the full payment term.

This guide walks through exactly how the process works, step by step, with a worked example so you can see the real numbers rather than just the concept.

The Process, Step by Step

1. You deliver the goods or service and issue an invoice as usual — nothing changes about how you run your sales process.
2. You submit the invoice to a financing provider along with supporting documents (purchase order, delivery confirmation, and your customer's payment history if available).
3. The provider verifies the invoice — checking the customer's creditworthiness (not just yours) and confirming the invoice is genuine and undisputed.
4. You receive an upfront advance — typically 70-90% of the invoice's value — usually within a few days of approval.
5. Your customer pays the invoice as normal, on their usual payment terms, to either you or the financing provider depending on the structure.
6. You receive the remaining balance, minus the provider's fee, once the customer's payment is received.

A Worked Example

Say you've issued a S$50,000 invoice to a customer on 60-day payment terms, and you're approved for financing at an 80% advance rate with a 2% fee:

In this example, instead of waiting 60 days for the full S$50,000, you'd have S$40,000 in hand within days — enough to cover payroll, restock, or take on the next job — and the remaining S$9,000 once your customer settles the invoice.

Recourse vs. Non-Recourse Financing

One detail worth understanding before you sign anything: in recourse financing, if your customer never pays, you're responsible for repaying the advance. In non-recourse financing, the provider absorbs that risk instead — but this protection comes at a higher fee, and usually only applies to genuine non-payment, not disputes over the goods or service delivered. Most invoice financing in Singapore is recourse-based; non-recourse structures exist but are less common and priced accordingly.

What You'll Need to Apply

• Copies of the outstanding invoice(s) and related purchase orders
• Your customer's payment history, if available — this matters more than your own credit profile in many cases
• ACRA business profile and basic financial documents

Because approval is weighted heavily toward your customer's creditworthiness rather than yours, this route can work even for younger businesses that wouldn't yet qualify for a standard business term loan — provided their customers are established, creditworthy companies. For a broader look at how this compares to other financing routes on cost and speed, see our bank loan vs. alternative financing guide.

Who This Suits Best

• B2B businesses with longer customer payment cycles (30-90 days)
• Companies with a handful of large, reliable corporate customers rather than many small ones
• SMEs that want financing that scales naturally with sales, rather than a fixed loan amount

How Reliance Advisors Helps

Advance rates, fee structures, and recourse terms vary significantly between providers — a 2% fee from one provider and a "2% weekly" fee from another can mean very different actual costs for the same invoice. We compare structures across our lender panel so you can see the real, dollar-for-dollar cost before committing to one. See our receivables financing page for indicative ranges, or get a specific quote for your invoice.

Figures in the worked example are illustrative only, based on typical advance rates and fee structures observed in the Singapore market as of mid-2026. Actual rates, advance percentages, and fees vary by provider, invoice size, and customer credit profile — always request a specific quote for your own invoice before proceeding.
