Account receivables optimization: 6 strategies for B2B SaaS

Late payments happen. They're part of B2B revenue cycles.

Last year, over half (55%) of all B2B invoiced sales in the U.S. were paid late.

While common, doesn't mean it's acceptable. This translates directly into cash flow pressure, strained customer relationships, and significant time lost chasing what's already owed.

The fix isn't just sending more reminder emails. It's building a smarter, more intentional accounts receivable process that reduces friction at every stage, from invoice creation to cash collection.

That's what account receivables optimization is all about. And whether you're managing a small finance team or scaling a high-volume B2B operation, the principles are the same.

In this guide, we'll break down what AR optimization actually means, why it matters, the best practices that make a real difference, and how to start improving your process today.

What is account receivables optimization?

Accounts receivable (AR) refers to the money your business is owed by customers for goods or services already delivered but not yet paid for. It lives on your balance sheet as a current asset, money you've earned but haven't collected yet.

Account receivables optimization is the systematic process of improving how your business manages that collection cycle. The goal is to get paid faster, with less effort, and with fewer disputes along the way.

It covers everything from how you send invoices and what payment terms you offer, to how you follow up on overdue accounts and measure performance.

Think of it as designing a smoother, faster path from "invoice sent" to "payment received."

Account receivables optimization: Areas and terms

When optimizing your AR process, a few areas and terms will come up. To make sure we cover the basics, let's align on what those entail.

6 best practices for account receivables optimization

There's no single lever that fixes AR. The businesses that collect most efficiently tend to get several things right at once.

Here are the practices that consistently make the biggest difference.

1. Set clear payment terms from the start

Late payments often start with ambiguous expectations. If your payment terms aren't clearly defined in your contracts, quotes, and invoices, customers have every reason to deprioritize your invoice.

Best-in-class AR teams dot the following to optimize the process from the start:

• Define net payment terms explicitly (e.g., Net 15, Net 30) and include them on every document
• Specify late payment penalties upfront so there are no surprises
• Offer early payment discounts (e.g., 2/10 Net 30) to incentivize faster collection
• Get payment terms agreed to in writing before work begins, not after

2. Send accurate invoices immediately

Every day between delivery and invoicing is a day added to your DSO before the clock even starts. Delays in sending invoices, or sending invoices with errors, are among the most common and easily fixable causes of late payment.

According to Billentis, invoice errors and disputes account for a significant portion of payment delays in B2B transactions. Getting invoices right the first time removes one of the most common reasons customers use to delay payment.

Practical steps:

• Invoice immediately upon delivery, not at the end of the month
• Include all required details: PO numbers, line item descriptions, agreed prices, and payment instructions
• Use invoice templates that match your customers' procurement requirements
• Confirm receipt of invoices for high-value customers

3. Automate follow-ups with a structured cadence

Manual chasing is inconsistent and exhausting. Structured and automated dunning management ensures that no invoice slips through the cracks, and that your team's energy is focused on the accounts that need human attention.

A typical AR follow-up cadence might look like this:

The exact cadence should be calibrated to your customer relationships and industry norms, but having one at all puts you ahead of most businesses.

4. Segment your receivables by risk

Not all outstanding invoices deserve the same level of urgency. Treating a $500 overdue invoice the same as a $50,000 one is a poor use of your team's time.

Effective AR teams segment their receivables by:

• Invoice age: Current, 1–30 days late, 31–60 days, 60+ days
• Customer payment history: Reliably late vs. chronic non-payers
• Invoice value: High-value invoices warrant more direct outreach
• Dispute status: Is there a genuine dispute that needs resolution before payment?

This kind of prioritization is much easier when your AR data is centralized and visible.

5. Make it easy to pay

Friction at the payment stage is a (not so) silent killer of collection rates. Here, even the smallest hurdle can cause delays.

If a customer has to find a bank account number, or navigate a clunky payment portal, or worst case, they'll have to call someone, they'll often just... wait.

That's why you want to remove as many barriers as possible:

• Offer multiple payment methods (ACH, credit card, bank transfer, cheque)
• Include a direct payment link in every invoice email
• Enable self-service payment portals so customers can pay on their schedule
• Accept digital payments and consider integrating with your customers' AP systems

6. Track the metrics that matter

As the age old saying goes: You can't optimize what you don't measure.

B2B companies with the strongest AR processes have a short list of metrics they obsess over and as such, review on a regular basis.

How to optimize your accounts receivable process: A step-by-step approach

Knowing the best practices is one thing. Building a process around them is another. Here's a practical sequence to follow whether you're starting from scratch or improving an existing setup.

Step 1: Audit your current state

Before you can optimize, you need to understand where you are today. Pull your aging report and answer these questions:

• What's your current DSO? How does it compare to your payment terms?
• What percentage of your AR is over 30 days old? Over 60 days?
• How much of your overdue balance is concentrated in a small number of customers?
• Are there recurring patterns in disputes or delays?

This audit gives you a baseline and surfaces where the biggest wins are likely to come from.

Step 2: Standardize your invoicing

Create a consistent invoicing process that your whole team follows:

1. Define a standard invoice template that includes all required fields
2. Set a rule for how quickly invoices must be sent after delivery (e.g., same day)
3. Implement a review step for high-value invoices before they go out
4. Build in a confirmation step for any customer that has previously disputed invoices

Step 3: Set up your follow-up cadence

Design your collection cadence based on your typical customer profile and industry. Configure this as an automated workflow where possible so reminders go out consistently without requiring manual action each time.

If you're using account receivables software, this is usually a built-in feature. If you're working with spreadsheets and email, even a simple calendar-based checklist is better than no system at all.

Step 4: Segment and prioritize your receivables

Run your aging report at least weekly. Flag any invoice that crosses a key threshold (e.g., 15 days overdue) for manual review. Assign your team's follow-up time based on invoice value and customer risk profile, not just invoice age.

Step 5: Reduce payment friction

Review your current payment process through your customer's eyes. How many steps does it take to pay you? What could you remove, automate, or simplify? Even small improvements here can meaningfully reduce DSO.

Step 6: Measure, review, and iterate

Set a monthly review cadence for your core AR metrics. Compare month over month and quarter over quarter. When you spot a trend, DSO creeping up, bad debt increasing, trace it back to the root cause before assuming you need a new tool or more headcount.

Most AR problems are process problems, not resource problems.

B2B accounts receivable optimization: what's different

B2B AR comes with a distinct set of challenges that consumer-facing businesses don't typically face:

• Longer payment terms: Net 30, 60, or even 90 is common in B2B, which extends the natural cash conversion cycle
• Higher invoice values: The stakes per invoice are higher, so disputes and delays have a bigger impact
• Procurement complexity: Many enterprise customers require PO numbers, vendor onboarding, and specific invoice formats before they'll process payment
• Relationship sensitivity: You can't be as aggressive in collections as you might be with anonymous customers; the relationship has long-term value
• Volume at scale: As your customer base grows, manual AR processes break down fast

For B2B teams specifically, the case for structured processes and purpose-built tooling is even stronger. The combination of high invoice values, complex procurement requirements, and relationship sensitivity means that ad hoc AR management carries significant financial and reputational risk.

Optimize your accounts receivable process: Where to start

If you take one thing from this guide, let it be this: accounts receivable optimization isn't a one-time project. It's an ongoing discipline.

The businesses that collect fastest aren't necessarily using the most sophisticated software, they're the ones with:

• The clearest processes
• The most consistent follow-up
• The best visibility into their receivables at any given moment

Start with your audit and find out where your cash is getting stuck, then fix one thing at a time.
