Adfin | Automated payment chasing vs. collection agencies explained

Unpaid invoices are one of the most persistent headaches for small and mid-sized businesses. According to a recent survey, 56% of small businesses reported being owed money from unpaid invoices, averaging $17,500 per business (Intuit QuickBooks). That's cash trapped in limbo, unable to fund payroll, stock, or growth.

When invoices go unpaid, businesses typically face two paths: automated payment chasing or handing the account to a collection agency. Both aim to recover what you're owed, but they operate at different stages, carry different costs, and leave very different impressions on your customers. Understanding how they compare helps you build a smarter accounts receivable (AR) strategy, one that collects faster without burning bridges.

What is automated chasing and how does it work?

Automated payment chasing is software-driven invoice follow-up that runs from within your business. Instead of manually emailing or calling customers about overdue bills, the platform sends scheduled, personalised reminders before and after each invoice due date. These reminders go out via email, SMS, or even WhatsApp, depending on the tool.

The key distinction is timing. Automated chasing is proactive. It nudges customers when a payment is approaching, not just after it's late. Reminders are typically branded with your company's name and tone, so they feel like a natural extension of your relationship rather than a threatening letter from a stranger.

Platforms like Adfin take this further by integrating directly with accounting software such as Xero and QuickBooks. This means invoice data stays synchronised, reminders reflect accurate balances, and payments are reconciled automatically. The result is a hands-off process that keeps cash flowing while you focus on running your business.

The impact of this kind of automation is measurable. Companies that automate more than half of their AR processes report a 32% decrease in Days Sales Outstanding (DSO), equivalent to a reduction of 19 days (SolveXia). That's nearly three fewer weeks waiting for money you've already earned.

How do collection agencies differ?

Collection agencies operate on an entirely different model. They're third-party firms that step in after an invoice has gone significantly overdue, typically 60, 90, or even 120 days past due. When you hand an account to an agency, they take over communication with your customer and attempt to recover the debt on your behalf.

Most agencies work on a contingency basis, meaning they charge a percentage of whatever they successfully collect. Fees commonly range from 20% to 50% of the recovered amount, depending on the age and size of the debt. Some agencies also charge flat fees or require minimum commitments.

The tone of agency communications tends to be more formal and assertive. While reputable firms follow legal guidelines, the shift from your brand's voice to an agency's can feel jarring to customers. This is why 60% of small business founders say they avoid confronting customers over delinquent bills for fear of damaging the relationship (Old National Bank). For many, handing off to an agency feels like crossing a line they can't undo.

What is the difference between automated chasing and outsourced collection agencies?

While both approaches aim to recover unpaid invoices, they differ across several important dimensions. Here's a clear comparison:

Cost structure: Automated chasing tools typically charge a flat subscription or per-transaction fee, making costs predictable. Collection agencies take a percentage of recovered funds, which can significantly eat into the amount you actually receive.
Customer relationship impact: Automated reminders come from your business, in your tone, preserving the customer relationship. Agency communications come from a third party and often carry a more confrontational tone.
Timing in the AR lifecycle: Automation works across the entire invoice lifecycle, from pre-due-date nudges to post-due follow-ups. Agencies typically only engage once a debt is severely overdue.
Control: With automated chasing, you decide the messaging, frequency, and escalation path. With an agency, you hand over control of the customer interaction entirely.
Speed of intervention: Automated systems act immediately and consistently. Agencies may take days or weeks to begin outreach after receiving an account.

The data supports the value of early, automated intervention. AR automation has helped finance teams achieve a 33-day reduction in DSO and a 50% reduction in 90-day aged accounts (Tesorio). Fewer invoices reaching the 90-day mark means fewer accounts that ever need an agency in the first place.

When does each approach make the most sense?

Automated payment chasing is the right fit for the vast majority of outstanding invoices. Most late payments aren't malicious. Customers forget, lose the invoice in their inbox, or simply need a gentle prompt. Automation handles these cases efficiently without human effort.

Collection agencies, on the other hand, are best reserved for accounts that have genuinely gone cold. If a customer has ignored multiple reminders over 90 or more days and shows no intention of paying, professional debt recovery may be the only option left. This is particularly true for larger sums where the potential recovery justifies the agency's fee.

The numbers highlight why acting early matters. 47% of small businesses reported a portion of their invoices were overdue by more than 30 days, with nearly 1 in 10 invoices falling into this category on average (Intuit QuickBooks). An automated system catches these invoices at the 30-day mark and applies consistent pressure, reducing the chance they ever age into collection territory.

Can automated chasing and collection agencies work together?

Absolutely, and this is where the smartest AR strategies live. Rather than viewing automated chasing and collection agencies as competing options, think of them as complementary stages in a single workflow.

Automation handles prevention and early intervention. It ensures every invoice receives timely, polite follow-up from day one. When a customer pays after the second or third reminder, the system resolved the issue without any human involvement and without any relationship damage.

For the small percentage of accounts that don't respond to automated outreach, escalation to a collection agency becomes the logical next step. Some platforms even offer built-in escalation paths that connect to vetted collection partners, making the handoff seamless.

This layered approach pays off in measurable ways. Companies using AR automation have seen a 10-15% reduction in bad debt write-offs, and automated invoicing alone leads to a 15% drop in bad debts (Resolve Pay). By catching overdue invoices early, you shrink the pool of accounts that need aggressive recovery.

Additionally, 85% of CFOs at companies that have automated more than half of their AR processes cited a decrease in DSO (NetSuite). The pattern is clear: automation first, agency escalation as a last resort.

Adfin's platform supports this layered approach by automating payment chasing across multiple channels while keeping your accounting data in sync. When escalation is needed, having a clean record of all automated touchpoints gives any collection partner the context they need to act quickly.

FAQs

Will automated payment chasing damage customer relationships?

No. Automated reminders are sent in your brand's voice, with personalised messaging and a polite tone. Customers see them as a routine part of doing business, similar to receiving a receipt or order confirmation. Unlike agency letters, automated chasers don't carry the stigma of formal debt recovery.

How much do collection agencies typically charge?

Most agencies charge between 20% and 50% of the amount they recover, depending on the debt's age and complexity. Older debts carry higher fees. By contrast, automated chasing platforms like Adfin use transparent, per-transaction pricing with no monthly fees, so you keep more of what's collected.

At what point should a business escalate to a collection agency?

A common threshold is 90 days past due. If automated reminders, phone follow-ups, and escalation emails have all failed to produce a response, it's reasonable to consider third-party recovery. Some businesses set the threshold at 120 days, depending on the customer relationship and invoice size.

Can small businesses afford automated payment chasing software?

Yes. Many platforms are designed specifically for small and mid-sized businesses, with pricing models that scale with usage. Adfin, for example, charges only per successful transaction with no monthly minimums, making it accessible even for businesses with a small volume of invoices.

Does automated chasing work for B2B and B2C invoices?

Automated chasing works well for both. B2B invoices often involve longer payment terms and established relationships, making polite reminders especially effective. B2C invoices benefit from multi-channel reminders via email, SMS, and WhatsApp, meeting customers wherever they're most responsive.

What happens to customer data when using a collection agency?

When you assign an account to an agency, you share customer contact details and invoice information with a third party. Reputable agencies follow data protection regulations, but you're still handing over sensitive information. With in-house automated chasing, customer data stays within your existing systems.

How quickly can automated payment chasing show results?

Many businesses see improvements within the first billing cycle. Automated reminders sent before the due date often prompt on-time payments that would otherwise have been late. Over a few months, the cumulative effect on DSO and cash flow becomes significant.

Choosing the right strategy for your business

The most effective AR strategy isn't about choosing between automated payment chasing and collection agencies. It's about using both at the right time. Start with automation to catch the majority of late payments early, preserve customer relationships, and keep costs predictable. Reserve agency escalation for the stubborn minority of accounts that have exhausted every other option.

For small and mid-sized businesses, the priority should be reducing the number of invoices that ever reach the collection stage. Automated platforms handle this at scale, freeing your team to focus on growth rather than chasing payments. The result is healthier cash flow, stronger customer relationships, and fewer write-offs.
