Pricing comparison · facts checked November 12, 2026
Monk pricing and OnDue pricing, compared.
Monk sets its price by business volume and shares it on a demo. OnDue publishes its early-access prices. Here is what each says, with a source for every Monk fact, and the questions that decide what you’ll really pay.
The short answer
As of , Monk doesn’t publish a price. Its homepage says pricing scales with business volume and asks you to book a demo, and its pricing guide says the fee is flat, not a percentage of what you collect.
OnDue’s early-access prices are on the page: Solo $49/mo, Starter $79/mo, Growth $249/mo, Scale $599/mo and Enterprise custom-priced and billed yearly. Nobody is charged during early access.
Monk does more than OnDue (phone calls, AP portals, broader cash application, many more ERPs), so a lower price isn’t the whole story. The full OnDue vs Monk comparison covers features.
Line by line
Monk facts are from Monk’s own pages, read on November 12, 2026. Where Monk publishes nothing, we say so instead of guessing.
Published price
None. The pricing question on Monk’s homepage answers: “Pricing scales with business volume. Book a demo to learn more.”
Source: monk.comYes, on the pricing page: Solo $49/mo, Starter $79/mo, Growth $249/mo, Scale $599/mo, and Enterprise custom-priced, billed yearly. These are early-access prices.
What the price depends on

Source: monk.com/blog/ar-automation-pricing0%. OnDue never takes a cut of your invoices.
How you get a price
Book a demo. Monk’s llms.txt says pricing details are shared on a demo.
Source: monk.com/llms.txtRead it on the pricing page, then request early access. No call needed.
Setup and implementation
The homepage says every customer gets a dedicated engineer, support, an implementation specialist and an agent specialist, and that the typical customer time commitment is 1 hour to launch. We found no published implementation fee.
Source: monk.comNo setup fee. You connect your books yourself. Scale and Enterprise include a dedicated onboarding lead.
Seats
Not published.
2 on Solo, 3 on Starter, 5 on Growth, 15 on Scale, unlimited on Enterprise. Extra seats are $20/mo each.
Fees on customer payments
Not published. Monk’s llms.txt says customers can pay by ACH, wire, check or card in its Payment Hub.
Source: monk.com/llms.txtCustomers pay with Link, card or US bank account (ACH) on OnDue’s Stripe pay page, into your own Stripe account. OnDue adds no fee on payments. During early access OnDue also covers Stripe’s processing fee, so you receive the full amount, and we’ll tell you before that changes.
Free trial
We found no free trial or self-serve signup. Monk’s pages ask you to book a demo.
Source: monk.comBilling hasn’t started, so nobody is charged during early access. Reminders wait for your approval, so you can read the drafts before any customer sees one.
Annual billing and discounts

Six questions for any quote
What you pay in year one is more than the platform fee. Ask every vendor, OnDue included, and get the answers in writing.
- What is the platform fee in year one, and in year two? Ask whether the renewal price is capped.
- Is there an implementation or onboarding fee? And what you have to do yourself before the first reminder goes out.
- How many people can log in, and what does one more cost? Include the people who only approve or read.
- What does it cost when a customer pays? Card, ACH and wire fees, and whether any of them go to the vendor.
- What does “volume” mean in my quote? Revenue, invoices, customers or entities, and what happens when you grow past it.
- How long is the contract, and how do I leave? Notice period, auto-renewal, and how you get your data out.
