Duesteer vs Chaser: Which Is Right for Managing Overdue Invoices?

Duesteer vs Chaser at a glance

Both products deal with money that has been invoiced and not yet paid, but they solve that problem at different levels.

Duesteer is a guided recovery app for an individual or a small service business. It assumes you already have an overdue invoice and a client you know.

Chaser is an accounts receivable platform for businesses managing receivables at scale, with automated chasing across many customers and invoices at once.

What Duesteer is designed for

Duesteer is for the person who has already sent an invoice, watched the due date pass, and now has to decide what to do. That usually comes down to a few questions:

• When should the next follow-up go out?
• How firmly should it be worded?
• What changes when a client gives a payment date and misses it?
• How should a genuine dispute be handled?
• When is it reasonable to move to a final notice or seek outside help?

Duesteer answers those with a guided escalation ladder and a recommended next action for each invoice. It is not trying to become an accounting suite or a full receivables system, so there is no ledger to reconcile and nothing to connect before you can use it.

What Chaser is designed for

Chaser is an accounts receivable automation platform aimed at small and mid-sized businesses, accountants and bookkeepers. Its documentation describes chasing schedules that run once configured, reminders by email, SMS and scheduled text-to-speech Auto-call, syncing with accounting systems, payment collection through Chaser Pay, and forecasting across the receivables ledger.

That breadth is the point. A finance team chasing hundreds of invoices cannot handle each one personally, and automation is the realistic way to keep the process consistent. More automation is not a weakness here; it is the right answer to a different problem.

Guided recovery vs automated chasing

This is the real difference between the two products, and it matters more than any feature count.

Duesteer

Duesteer works out which stage an invoice has reached and helps you prepare wording that fits it, from a light nudge through to a formal demand. You read the message, change what you want, and send it from your own mail app. Invoice recovery data is stored locally on your device, and Duesteer does not send messages to clients automatically.

Chaser

Chaser runs recurring receivables activity for you. Reminders go out on a schedule across email, SMS and Auto-call, which removes the need to chase invoice by invoice. People stay involved where judgement is needed: its AI email generator reads incoming debtor emails, detects intent such as a promise to pay or a dispute, and drafts a reply that a user reviews and edits before it is sent.

The better approach depends on the kind of recovery work you need to manage. Duesteer optimises for control and context. Chaser optimises for consistency and scale.

Disputes and missed payment commitments

These two events change a recovery process more than anything else, and they are where Duesteer does its most useful work.

Duesteer

A real dispute changes what should happen next. Escalating while a client genuinely disagrees about scope or quality damages both your position and the relationship. Duesteer lets you pause recovery while the disagreement is worked out, keeps the dispute attached to the invoice, and lets you resume once it is resolved rather than starting the sequence over.

Payment commitments work the same way. A promised payment date is recorded and follow-ups hold until then. If the date passes without payment, that missed commitment is recorded as a recovery event in its own right, and the next suggested action reflects it instead of repeating the same reminder as though the promise was never made.

The result reads as a sequence of events rather than a pile of reminders. When you later write a final notice, you have dates, commitments and outcomes tied to the invoice, exportable as a PDF on Premium.

Chaser

Chaser documents both capabilities. An invoice can be marked In Dispute with a reason and notes, then filtered, reported on, moved onto a schedule that does not chase, or have follow-ups stopped and restarted in bulk. An expected payment date can be set on an invoice; chasing stops until that date passes and resumes automatically if the invoice has not been paid or reconciled in the connected accounting system.

So both products handle disputes and promised dates. The difference is framing. Chaser treats them mainly as controls over whether automated chasing should run. Duesteer treats them as events that change what the next human decision should be.

Keeping the client relationship under your control

Chasing an invoice is uncomfortable because two goals pull against each other. You want to be paid, and you often want to keep working with the client afterwards.

Duesteer supplies the structure, the timing and a draft, but you decide what is sent. If a client has been reliable for three years and this is their first late invoice, you can soften a message. If the same client has missed multiple payment commitments, that history gives you important context when deciding how firmly to proceed.

This matters most where the person who delivered the work also manages the relationship, the normal situation for consultants, freelancers and small service businesses.

Integrations, setup and payments

Duesteer does not currently integrate with Xero, QuickBooks or other accounting platforms, and it does not collect invoice payments. Invoices are entered manually, so setup takes a few minutes with nothing to connect or authorise, and clients pay you the way they always have. That suits someone tracking a small number of overdue invoices.

Chaser is built the other way, and for its audience that is an advantage. It connects to Xero, QuickBooks Online, Sage, NetSuite and Microsoft Dynamics 365 Business Central among others, syncing invoice and payment data so nobody retypes it. Chaser Pay adds a payment portal reached from a link in its reminders, supporting bank transfer, cards, Apple Pay, Google Pay and open banking. For a finance team, both are real reasons to choose a platform like Chaser.

Pricing

Duesteer is free for up to two invoices. Premium costs $9.99 per month or $59.99 per year, billed through Apple, with details on the pricing page.

Chaser Compact starts at $259/month in the US as of August 7, 2026, covering four users, thirty follow-up templates and four automated receivables workflows. Core and Complete are priced higher and add unlimited users, multi-entity support and, on Complete, a receivables forecast. Plans and prices change, so check Chaser's official pricing page for current figures.

The two figures are not directly comparable. Chaser's pricing reflects a platform bought by a business with a receivables function and several people using it, while Duesteer's reflects an app bought by one person managing their own overdue invoices.
