10 Ways to Get Cash From Unpaid Invoices Quickly (2026)

TL;DR: The fastest ways to get cash from unpaid invoices include invoice factoring, invoice financing, early-payment discounts, and direct collection tactics like calling the customer’s AP department. The right option depends on whether the invoice is current, overdue, or disputed. Valid B2B invoices owed by creditworthy customers can often be funded within 24 to 48 hours after facility approval. Disputed or stale invoices generally need a collection or legal strategy, not a financing product.

Ways to Get Cash From Unpaid Invoices Quickly

Getting cash from unpaid invoices means converting accounts receivable into usable funds before the customer pays on normal terms. The main methods fall into three categories: making the customer pay faster (payment links, reminders, early-payment discounts), financing the receivable (invoice factoring, invoice financing, AR lines of credit, asset-based lending), or recovering overdue debt (collection agencies, demand letters, legal action).

The fastest option is not always the best option. A phone call to accounts payable costs nothing. Factoring an invoice can deliver cash within a day. Filing a lawsuit can take months. The right way to get cash from an unpaid invoice depends almost entirely on the invoice’s status: is it current, late, disputed, or effectively bad debt?

If you already know you need receivables-based funding, explore invoice factoring options available for Canadian businesses.

Why Unpaid Invoices Create Cash Pressure

B2B payment terms are the root cause. When a business completes work and invoices a customer on net 30, 60, or 90 day terms, payroll, rent, suppliers, and taxes do not wait. The gap between delivering value and receiving payment is where cash-flow problems live.

Canadian data confirms this is widespread, not isolated. According to Xero’s Canada Small Business Insights report, Canadian small businesses were paid 11.3 days late on average in the June quarter of 2026, with the average time from invoice to payment sitting at 29.0 days. That is worse than the 2025 average of 10.5 days late.

The numbers get more concerning at scale. Atradius reports that 44% of B2B invoice value in Canada was overdue, and 7% was classified as bad debt. Average payment terms from invoicing stood at 45 days.

The impact is concrete. QuickBooks found that 59% of small businesses had invoices overdue by 30 or more days, with the average amount owed reaching $17,700. Nearly 39% of owners said just one late payment made it hard to cover payroll or bills.

BDC provides a useful benchmark: for a company with $1 million in annual sales, reducing the average collection period from 45 days to 30 days frees up roughly $41,000 in cash by year-end. That is money already earned but sitting in someone else’s bank account. For a deeper look at the mechanics behind these gaps, read this working capital guide.

First, Diagnose the Invoice

Before choosing a way to get cash from an unpaid invoice quickly, determine what kind of “unpaid” you are dealing with. This step matters because the wrong solution can waste money or make the situation worse.

Outstanding but Not Yet Due

The invoice has been sent, but the customer is still within agreed payment terms. This is the most financeable scenario. The invoice is fresh, valid, and owed by a customer who has not actually done anything wrong. Invoice factoring, invoice financing, AR lines, early-payment discounts, and supply chain finance programs all work well here.

Overdue but Not Disputed

The due date has passed. The customer may have forgotten, their AP department may be slow, or they may be having temporary cash problems of their own. Best approach: reminders, phone calls to AP, a specific payment date request, a partial payment, or a payment plan. Some factoring providers will still finance a slightly overdue invoice if it remains undisputed and the customer is creditworthy.

Practitioners on Reddit report that large B2B customers routinely pay 60 to 75 days after invoice, even when terms say net 30. One Canadian service-business owner described this as a structural working-capital cost rather than a one-off problem. Responses recommended formal POs, direct deposit setup, and treating slow payment from large customers as a financing need rather than a collection issue.

Disputed

The customer is questioning the work, the amount, or the terms. Stop treating this invoice as a financing asset until the dispute is resolved. A practitioner article on LinkedIn from Factor Finders explains that factoring companies often pause funding, withhold reserves, or refuse advances when invoices are disputed. Disputes remain the seller’s operational responsibility even where non-recourse factoring applies.

Stale or Doubtful

The invoice is significantly past due, the customer refuses to pay, or the customer may be insolvent. Factoring is usually not the answer here because factors want collectible receivables, not defaulted debts. This is where demand letters, collection agencies, debt sale, or legal action come into play.

The key distinction: a factoring company finances a good invoice. A collection agency chases a bad debt. Allianz Trade Canada draws this line clearly, noting that factors typically handle debts not yet overdue, while collection agencies pursue overdue accounts for a fee.

The Fastest Ways to Get Cash From Unpaid Invoices

Here are the main options, ordered from simplest to most complex. Each one fits a different situation.

1. Add Payment Links and Remove Friction

The cheapest way to get cash from an unpaid invoice is to make it easier for the customer to pay. Adding a “pay now” button, accepting credit card or EFT payments, and sending invoices electronically can compress payment timelines significantly. QuickBooks reports that online payment buttons help invoices get paid up to four times faster than paper invoices.

2. Call the AP Department

Before financing anything, pick up the phone. Ask the customer’s accounts payable team when payment is scheduled, whether they received the invoice, and if anything is holding it up. Many payment delays are process issues, not refusals.

3. Offer an Early-Payment Discount

A small discount for fast payment can be cheaper than financing. The classic structure is 1/10 net 30: a 1% discount if the customer pays within 10 days, otherwise full payment in 30 days. BDC cautions that discounts are costly and should be reserved for situations when cash is genuinely needed quickly.

4. Request a Partial Payment or Payment Plan

If the customer cannot pay in full, ask for a partial payment now with the remainder on a schedule. This converts a fully unpaid invoice into immediate partial cash plus a documented repayment plan.

5. Use Invoice Factoring

Sell the invoice to a factoring company in exchange for an immediate cash advance, typically 70% to 90% of invoice value. The factor collects from your customer and later releases the remaining balance minus fees. Once a facility is approved, funding can often arrive within 24 hours of submitting an invoice.

6. Use Invoice Financing or an AR Line of Credit

Instead of selling the invoice, use it as collateral for an advance. The business often retains ownership and may continue collecting from the customer. This structure can be more confidential than factoring.

7. Use Invoice Discounting

A form of invoice finance where the provider advances funds but does not take over sales ledger management. The arrangement is often undisclosed to customers, making it suitable for businesses that want to preserve client relationships. It requires stronger internal credit control.

8. Use Supply Chain Finance

If a large buyer offers a supply chain finance program, approved invoices can be paid early by a financing partner. The cost may be lower than supplier-initiated factoring because it is priced on the buyer’s credit, not the supplier’s.

9. Use a Bank Line of Credit or Asset-Based Lending

A revolving line secured by receivables, inventory, or other business assets can fund working capital gaps without selling individual invoices. Setup is slower, but ongoing access is flexible and often cheaper. Compare the trade-offs between factoring and a traditional bank facility in this guide on factoring vs. bank lines.

10. Use Collections, Debt Sale, or Legal Action

For old, refused, or doubtful debts, these are recovery tools. A collection agency pursues overdue accounts. Debt can be sold at a steep discount. Legal action through small claims or civil court is an option for larger amounts (in Ontario, the Small Claims Court maximum is $35,000).

Invoice Factoring vs Invoice Financing vs Collections

These three terms cause the most confusion when businesses look for ways to get cash from unpaid invoices quickly. Here is a clear breakdown.

Invoice factoring means selling the invoice to a third-party factor. The factor takes over collection, and the customer typically pays the factor directly. Advances run 70% to 90% of invoice value. The customer usually knows the business is using a factor.

Invoice financing means borrowing against the invoice. The business keeps ownership and may continue handling collection. The arrangement can be confidential. Stripe explains that invoice financing lets a business get an advance while retaining the invoice and remaining responsible for repayment once the customer pays.

Collection means pursuing an overdue debt. This is recovery, not financing. Canada.ca describes collection agencies as companies that recover unpaid debts, and creditors may hire them, use internal collectors, or sell debts outright.

The critical difference: factors finance good receivables. Collection agencies chase bad debts. The right path depends on which category the invoice falls into.

For businesses with a line of credit already in place, drawing on that facility may be faster and cheaper than either factoring or collections.

How Much Cash Can You Get Upfront?

Most invoice finance and factoring providers advance between 70% and 90% of the invoice value, with 80% to 90% being common for clean B2B receivables. The remaining balance (the reserve or holdback) is released after the customer pays, minus the provider’s fees.

A higher advance rate is not automatically better. It may come with higher fees, stricter recourse terms, or tighter reserve controls. The total cost of accessing cash matters more than the advance percentage alone.

Practitioners on Reddit with factoring-industry experience describe a typical small-business offer as an 85% advance with a 3% to 5% factoring rate over a 90-day recourse program, depending on how quickly the customer pays. They also note that factors review the debtor’s credit, not just the borrower’s, and may deny invoices where the customer has poor payment history.

What Does It Cost?

Most guides mention fees but skip the math. Here is how to think about the true cost of getting cash from unpaid invoices through financing.

The Simple Formula

Annualized cost estimate = (fee / cash advanced) x (365 / days outstanding)

This is not a legal APR disclosure. It is a practical comparison tool.

Example 1: 2% Fee, 85% Advance, 30-Day Payment

Invoice: $100,000
Advance: $85,000
Fee: 2% of invoice = $2,000
Cost on cash advanced: $2,000 / $85,000 = 2.35% for 30 days
Simple annualized estimate: roughly 28.6%

Example 2: 3% Fee, 85% Advance, 60-Day Payment

Invoice: $100,000
Advance: $85,000
Fee: 3% per 30 days for 60 days = $6,000
Cost on cash advanced: $6,000 / $85,000 = 7.06% for 60 days
Simple annualized estimate: roughly 42.9%

QuickBooks Canada notes that factoring fees can create effective annual rates of 20% to 50%, and frequent use can erode profit margins. Fee structures may be flat or variable, such as a percentage charged every 10 days.

Invoice finance can be rational when it protects payroll, captures a profitable order, or avoids supplier disruption. But it should not be used blindly when the financing cost exceeds the gross margin on the job. For a broader view of these trade-offs, see this guide on cash-flow financing explained.

Risks and Contract Traps to Watch

Recourse Liability

In recourse factoring (the most common type), the business must repay or replace the invoice if the customer does not pay. Allianz Trade Canada confirms the original company remains ultimately responsible for non-payment after a given period. Read the full breakdown in this guide to recourse invoice factoring.

Non-Recourse Carve-Outs

Non-recourse factoring may cover specific credit events like customer insolvency, but it often excludes disputes, offsets, warranty claims, short payments, and performance problems. A LinkedIn practitioner article by Michael Norris warns that some firms advertise non-recourse factoring but include broad contract exceptions that limit the protection significantly.

Customer Notification

Factoring usually requires customers to pay the factor directly, so they will know. Invoice discounting is typically undisclosed. If customer perception matters to the business relationship, this distinction is important.

Fee Escalators and Hidden Charges

Fees may increase weekly, every 10 days, monthly, or after set aging buckets. The longer the customer takes to pay, the more the financing costs. Some agreements also include minimum monthly volumes, all-invoice requirements, multi-year terms, and termination fees. Practitioners on Reddit emphasize comparing not just advance rate and headline fee, but also recourse terms, client notification, termination timing, and fee escalation before signing anything.

Margin Erosion and Dependency

If gross margins are 10% and factoring costs 3% to 5% of invoice value, the finance cost can consume a large share of profit. Always compare financing cost to gross margin, not just to invoice size. And if a business must factor every invoice just to survive, the underlying problem may be pricing, terms, customer concentration, or undercapitalization. Financing should support growth or bridge timing gaps, not mask structural issues.

What to Prepare Before Applying

Speed matters when looking for ways to get cash from unpaid invoices quickly. The faster a business can prove the invoice is valid and collectible, the faster a lender or factor can underwrite it.

Documents a Factor, AR Lender, or Broker May Request

AR aging report
Copies of invoices to be financed
Customer list and payment history
Purchase orders or contracts
Proof of delivery or completion (signed timesheets, bills of lading, milestone approvals)
Corporate documents and ownership details
Business bank statements (recent months)
Financial statements or management accounts
Tax compliance information
Details of existing liens, bank facilities, or PPSA/security registrations
Dispute history or credit memo history

For a complete checklist, see this guide on business loan document requirements for Canadian applicants.

What Makes an Invoice More Financeable

Invoices are easier to finance when they are issued to another business or government agency (not a consumer), supported by a purchase order or contract, for completed goods or services, undisputed, payable within normal commercial terms (30 to 90 days), owed by a customer with a decent payment history, and not already pledged to another lender.

Questions to Ask Before Signing

Before committing to any factoring or invoice financing agreement, ask:

What percentage of the invoice is advanced upfront?
Is the fee charged on the invoice amount or the advance amount?
Is the fee flat, daily, weekly, every 10 days, or monthly?
What happens to fees if the customer pays in 31, 45, 60, or 90 days?
Is the arrangement recourse or non-recourse, and what events are excluded?
Will customers be notified?
Who controls collections?
Is there a reserve or holdback, and when is it released?
Are there monthly minimums or volume requirements?
Are there termination fees or lock-in periods?
Must all invoices be factored, or can specific invoices be selected?
Can the facility work alongside a bank line, equipment financing, or other facilities?

These questions surface the real cost and risk of any facility. The headline advance rate tells only part of the story.

If unpaid invoices are creating a recurring cash-flow gap, submit a loan enquiry to compare factoring, AR finance, lines of credit, and other working-capital structures suited to your situation.

How to Reduce the Need for Invoice Financing Over Time

The cheapest cash is the invoice you never have to finance. Practitioners on Reddit consistently say that changing terms and payment structures matters more than choosing the right software.

One business owner shared that switching to milestone payments, upfront card payments, and automatic acceptance deadlines almost eliminated chasing unpaid invoices entirely. Others recommended requiring signed purchase orders, setting up direct deposit with customers before starting work, and running credit checks on new accounts.

Preventive steps that reduce future financing needs:

Invoice immediately upon delivery or completion
Use electronic invoices with embedded payment links
Require deposits or milestone payments on large jobs
Negotiate shorter terms when possible
Follow up within 24 hours of the due date
Run credit checks on new customers
Review AR aging weekly, not monthly

In the logistics sector, practitioners on Reddit’s r/FreightBrokers describe the cash gap as structural: freight customers push net 45 to 90, while carriers expect weekly payment. If you pay carriers weekly but customers pay net 60, the invoice cash gap is part of the business model, not a one-off emergency. That makes it a financing question, not a collection question. For more strategies, see these cash flow solutions for Canadian businesses.

Canadian Considerations

Collection rules, limitation periods, court procedures, and permitted collection practices vary by province and territory. If an invoice has moved from “slow pay” to “debt recovery,” speak with a lawyer or qualified advisor before taking action.

Atradius identifies invoice financing as a tool used by 36% of Canadian company respondents. The Canadian commercial finance market offers factoring, AR lines, bank operating lines, asset-based lending, and supply chain finance through specialized lenders and intermediaries. A broker can help compare structures when the business needs more than a single product.

FAQ

Can I sell unpaid invoices?

Yes, if the invoices are valid, earned, undisputed, and owed by a creditworthy business or government customer. This is called invoice factoring. If the invoice is already seriously overdue or disputed, a factor will likely reject it and you may need a collection or legal strategy instead.

Is invoice factoring the fastest way to get cash from invoices?

It can be one of the fastest financing options once approved, because the invoice itself supports the advance. However, a payment link, AP phone call, or early-payment discount can be faster and cheaper if the customer is willing and able to pay.

How much of an invoice can I get upfront?

Most providers advance 70% to 90% of invoice value, with 80% to 90% common depending on invoice quality, customer credit, industry, and facility structure.

What happens if the customer does not pay?

It depends on the agreement. In recourse factoring, the business may have to repay the advance or replace the invoice. Non-recourse factoring may cover specific credit events like customer insolvency but often excludes disputes or performance issues.

Will my customer know I am using invoice finance?

With factoring, customers often know because the factor collects directly. With invoice discounting or certain financing structures, the arrangement can be confidential.

Can startups get cash from unpaid invoices?

Possibly, if they have completed work, valid B2B invoices, and creditworthy customers. Because the funder evaluates the customer’s ability to pay, factoring can sometimes be accessible when traditional loans are not.

Is invoice factoring expensive?

Fees may look small but become expensive when annualized, especially if the customer pays late. Effective annual rates of 20% to 50% are common. Whether that cost is justified depends on the margin on the job and the cost of not having cash.

What is better: factoring or a line of credit?

A line of credit may be cheaper and more flexible if the business qualifies and has time to set it up. Factoring can be faster or easier when the business has strong invoices but limited traditional borrowing capacity. The right fit depends on cost, speed, customer notification preferences, and whether the need is one-time or ongoing.
