Kolleno vs Upflow 2026: pricing, turnover gates and fit

Kolleno and Upflow solve different halves of receivables. Kolleno runs order-to-cash in one system. Upflow leads on reporting and forecasting for B2B SaaS. Both gate entry on company size, so check the floor before you compare features.

Pricing checked July 2026. Review scores checked on the dates shown against each.

Kolleno starts above $1m turnover and gates automation above $10m. Upflow sells by ARR band, from $440 a month. Paidnice sits below both gates, from $69 (£49) a month.

Kolleno is an AI order-to-cash platform from London, founded in 2020. It puts collections, payments, cash application and credit risk in one system, and its reconciliation covers BAI2, NACHA and ISO 20022 bank files plus NetSuite foreign-exchange journals. Published plans start at USD 650 per user a month, above $1m turnover.

Upflow is an accounts receivable platform founded in Paris in 2018, headquartered in New York. It syncs invoices from Xero, QuickBooks Online, NetSuite, Sage Intacct, Stripe Billing and Chargebee, then runs reminder workflows and the stronger analytics of the pair: countback DSO, collection effectiveness, at-risk rate and cohort forecasting. Upflow pricing starts at $440 a month, a figure it does not show on its own pricing page.

What separates Kolleno from Upflow

Kolleno is broad and reconciliation-led. Upflow is narrow and analytics-led. The feature differences below all follow from that.

Kolleno bundles receivables, payments, reconciliation, credit risk and e-invoicing, with three AI layers in every subscription: insights, a copilot that drafts messages for review, and an agent that runs policy-based collections. Its reconciliation library runs to 36 help articles.

Kolleno also classifies disputes and deductions by reason code and ranks them for the collector, which is the part of collections a reminder tool leaves alone. Its published case studies name Deel, Miro, 1Password and Rakuten, which is the size of finance function it is built around.

Upflow does not create invoices. It syncs them, hosts them on a branded portal, and runs workflows of emails, SMS, letters, calls and tasks. What it does better is measurement: countback DSO against best possible DSO, collection effectiveness, at-risk rate over 90 days, cohort forecasting.

They part company on instalments. Kolleno splits balances weekly, monthly or bi-monthly; Upflow offers partial payments and promises to pay, with no instalment plan.

What size of business each one will take

Kolleno publishes hard turnover floors and seat minimums. Upflow publishes revenue bands instead, and no floor. This decides the answer before price does.

The second row is the one that matters. Workflows, auto-reconciliation and reporting sit on Business Plus, so the realistic entry point for a business that wants automation is two Business Plus seats above $10m turnover, not one BusinessPay seat above $1m.

Upflow bands its paid plans by annual recurring revenue instead: Grow for $0 to $10m, Scale for $10m to $50m, Strategic above $50m. No minimum is published, so a smaller company can open a conversation, but every paid tier is quoted by sales.

Kolleno vs Upflow pricing: what each one costs

Kolleno publishes USD per-user prices from $650 a month. Upflow pricing starts at $440 a month on Grow and $880 a month on Scale, neither figure shown on its pricing page.

Kolleno, as at July 2026: BusinessPay USD 650 per user a month, or USD 545 per user a month billed annually. Business Plus USD 1,245 per user a month, or USD 995 billed annually, two seats minimum. Enterprise tiers are quoted, and integrations, customisations and add-ons can carry extra charges.

Two things get reported wrongly. The vendor publishes dollar figures on a page that renders local currency, so a pound amount quoted at parity is likely a conversion. And per-user pricing compounds: two Business Plus seats cost USD 2,490 a month at the monthly rate, or USD 23,880 a year on the annual rate.

Upflow pricing starts at $440 USD a month for Grow, and $880 USD a month for Scale. Both figures come from third-party pricing captures, TrustRadius among them, rather than from Upflow, which removed dollar figures from its own pricing page between mid-2024 and 2026, so confirm both amounts with sales before you budget.

The Discover tier is free and carries no collection automation, so you cannot chase an invoice on it.

Late fees and statutory interest in Kolleno and Upflow

Neither tool computes statutory interest itself. Upflow documents applying late payment fees through NetSuite. We found no late fee or interest feature in Kolleno's product or help materials.

This matters most in the UK. Under the Late Payment of Commercial Debts (Interest) Act 1998 a business can charge the Bank of England base rate plus 8% a year, plus fixed compensation of £40, £70 or £100 by debt size.

The statutory rate is fixed in six-month blocks, taking the base rate in force at the end of December and the end of June, so a tool that does not track it cannot apply the correct rate across a long-overdue invoice. On this evidence, interest in either tool is ledger work. Our guide to the dunning process places fees in the escalation ladder.

Ledger depth: Xero, QuickBooks Online and NetSuite

Both list Xero and QuickBooks Online, and the depth behind those two listings is not comparable. The difference shows up as reconciliation work you do by hand.

Upflow's QuickBooks Online connector is one-way and polled every five minutes with no webhooks. Payments land in Undeposited Funds and need manual reconciliation, and custom fields cap at three, text only.

Kolleno's depth points the other way: BAI2, NACHA and ISO 20022 bank files, SFTP connections, match scoring, NetSuite multi-currency journals. Xero and QuickBooks Online are supported, but the investment sits on the ERPs. If Xero is your ledger, our comparison of credit control software for Xero covers that end.

Kolleno vs Upflow reviews

Kolleno scores 4.9 from 99 G2 reviews, latest 17 June 2026. Upflow scores 4.8 from 233, latest 3 June 2026. Both are high, and Upflow's sample is more than twice the size.

Kolleno reviewers praise collections speed and support; the recurring criticisms are navigation, reporting they want more customisable, and a basic mobile app. Upflow reviewers praise setup speed, integrations and named account managers; the recurring criticisms are rigid reporting when slicing data, email cosmetics, and not being able to select several invoices at once.

Where each of the three runs out

Every tool here has a limit that rules it out for some buyers. This is the one for each of them, ours included.

Kolleno

The honest limitation. Per-user pricing with a turnover floor, and the tier carrying workflows and reporting needs two seats above $10m. We found no late fee or interest feature. Reconciliation depth points at NetSuite rather than Xero or QuickBooks Online.

Upflow

The honest limitation. Pricing starts at $440 a month but appears nowhere on its pricing page, so budgeting means a sales call. No native late fee computation and no instalment plans. Statement generation is not documented. Automatic actions fire once a day at a fixed time, business days only, and your own SMTP disables open and click tracking.

Paidnice

The honest limitation. No bank-file cash application, so no BAI2, NACHA or ISO 20022 matching and no remittance parsing. No credit bureau scoring. Upflow reports on more metrics, countback DSO against best possible DSO among them. Standard plans run on Xero and QuickBooks Online only. The AI Credit Controller is in beta, and every message needs human approval before it sends.

The alternative under $10m: how Paidnice applies fees and interest

Paidnice runs late fees, statement interest, reminders, statements and payment plans on your Xero or QuickBooks Online ledger, from USD 69 (GBP 49) a month with no per-seat fee.

Essentials covers 150 invoices a month. A business sending 300 to 600 invoices a month sits on Pro, from USD 99 to USD 179 a month, still with no per-seat fee.

It is the third option for the segment both tools price past: businesses from about $500k ARR, sweet spot $1m to $20m, on Xero or QuickBooks Online, with a small finance team or none.

Paidnice is accounts receivable automation that enforces your payment terms, covering credit control and debtor management on your ledger. It is built for Xero and QuickBooks Online, priced fairly, with no contracts or lock-ins, and it is perfect for finance teams between $1m and $20m a year needing a robust accounts receivable system.

Two charge types run on the same customer group. An invoice late fee is charged per overdue invoice. A statement interest charge is charged per customer against the whole overdue balance, with a Bank of England base rate toggle that applies the correct base rate for each period an invoice spans. UK compensation of £40, £70 or £100 is applied as a fixed line item with its own income account.

Interest compounds by default, and simple interest is the setting you turn on deliberately. Accrued interest recalculates when a statement is sent, so the figure the customer opens is accurate that morning. The fee posts to the ledger as a Draft or Approved invoice, which is what puts it into your customer's payables system.

$1 billion collected on time across more than 1 million invoices since 2022.

Customers cut their average wait for payment in half, within 30 days. Paidnice won New Zealand Small Business App of the Year at the Xero Global App Awards 2026, and holds 5.0 from 82 Xero App Store reviews.

For a wider field, our Kolleno alternatives guide and Upflow alternatives guide rank five tools each, and the accounts receivable software page covers the category.

Which of the three to shortlist

Match the tool to the workload: reconciliation, reporting, or making your payment terms stick. If the workload is matching thousands of payments, Kolleno is the honest answer.
