**Biller Genie and Upflow are priced at opposite ends of the category, and neither one charges per user. Biller Genie publishes a formula: $49.95 a month plus 0.50% of every invoice collected, capped at $1,500. Upflow publishes nothing at all, on any of its four tiers.**

That makes the usual side-by-side impossible, because one number is a rate and the other is a quote. The work on this page is turning them into the same kind of number, finding where the two lines cross, and being clear about what you are buying on each side of that point.

**Related guides:** [the best Biller Genie alternatives](/reviews/best-biller-genie-alternatives/), [the best Upflow alternatives](/reviews/best-upflow-alternatives/), [how much you can charge in late fees](/resources/how-much-can-i-charge-late-fees/)

One vendor charges a rate, the other issues a quote, so the two headline prices cannot be set side by side as they stand. Biller Genie takes $49.95 a month plus half a percent of everything it collects, capped at $1,500, which is reached at $300,000 collected in a month. Upflow prints nothing on any of its four tiers. Making those two comparable is what this page is for.

## A percentage of collections against an unpublished quote

Neither vendor charges per seat, which removes the variable that usually decides these comparisons and leaves a published rate facing a sales conversation.

Biller Genie’s price is a formula you can run yourself. Take $49.95, add half a percent of whatever the tool collects for you that month, and stop at $1,500 for the percentage. Type in last month’s collections and you have next month’s bill without speaking to anybody.

Upflow’s price is a conversation. Nothing is printed on any tier, quotes are set by ARR band, and even the free tier has to be arranged through sales. The $440 figure for Grow and $880 for Scale were last verified in August 2026 and are not published by the vendor, so they are a place to start negotiating rather than a price.

So the order on this page came out of four questions rather than a feature count: what the vendor actually prints, what the bill does as the business grows, whether a late fee exists inside the product, and how much verified review evidence stands behind each one. Biller Genie takes the first and the third. Upflow takes the fourth outright, at 4.8 from 233 G2 reviews against a Xero App Store listing that carries 2.33 from 3. The second question is the crossover, and it has a number.

## Biller Genie and Upflow compared: the table

Two rows decide this and neither is a feature: what each vendor publishes as a price, and whether a late fee exists inside the product at all.

|  | [Biller Genie](#biller-genie) | [Upflow logo](#upflow) |

| Revenue fit | Not published; the bill scales with the value collected | Not published; quoted in ARR bands, under $10m, $10m to $50m, and $50m and above |

| Billing model | Monthly fee plus 0.50% of invoices collected, capped at $1,500 a month | Not published at any tier; every paid plan is a sales quote |

| From (monthly) | $49.95 plus 0.50% of invoices collected | Not published; Grow last verified at $440 and Scale at $880 |

| Ledger integrations | QuickBooks Online, QuickBooks Desktop, Xero, AccountingSuite | Xero, QuickBooks Online, NetSuite, Sage Intacct, Stripe Billing, Chargebee, Zuora |

| Late fee grain | Yes (one global rule, add-on); nothing is late until 30 days past due | No (via your ERP only) |

| Reminder grain | Yes (one global cadence per account) | Yes (multi-step workflows by invoice age, behavior and risk profile) |

| SMS | None found | Yes (in workflows, alongside email and letter) |

| Statements | Yes (as a reminder type) | Not verified |

| Payment plans | Yes (the customer requests, the merchant approves) | No (promise to pay and customer-initiated part payments only) |

| Payments | Yes (card and ACH through its own merchant stack, with surcharging and dual pricing) | Yes (ACH, cards and direct debit through the portal, with autopay) |

| AI | None found; the automation is rules-based | Yes (cash application, promise-to-pay detection, dispute signals) |

| Collections analytics | Dashboard level | Countback DSO against best possible DSO, collection effectiveness, at-risk rate above 90 days, aging |

| Rated | 4.8 from 26 on Capterra, 3.0 from 4 on G2, 2.33 from 3 on the Xero App Store | 4.8 from 233 on G2, 4.5 from 15 on Capterra, 5.0 from 1 on the Xero App Store |

| Last verified | Aug 2026 | Aug 2026 |

The rating row carries counts as well as scores because the two review bases are not the same size or the same age: 233 reviews on one platform against 26, 4 and 3 on three others, with the lowest of those three attached to a reported sync fault. Averaging them would hide the disagreement, so all of them are printed.

## 1. Biller Genie

Best for a US small business that would rather pay for collections out of what it collects, at $49.95 a month plus 0.50%

### What is it best for?

For a US small business that would rather pay for collections out of the money collected than negotiate a subscription, on QuickBooks Online, QuickBooks Desktop, Xero or AccountingSuite.

**Fits:** US small businesses on QuickBooks Online, QuickBooks Desktop, Xero or AccountingSuite with steady card and ACH volume. No revenue band is published; the bill scales with the value collected

**Regions:** United States. Founded 2019 with the software launched in 2020, head office in Orlando and an engineering office in Belfast

**Entry cost:** $49.95/mo plus 0.50% of invoices collected, capped at $1,500/mo, with no contract and cancellation any time. ACH is an add-on at $0.50 a transaction with a $20 monthly minimum and a $25 setup fee; paper mail is $1.50 a reminder plus $0.25 an extra page. As at August 2026, verify current pricing

**Rated:** 4.8 from 26 reviews on [Capterra](https://www.capterra.com/p/176347/Biller-Genie/reviews/), latest June 2025; 3.0 from 4 on [G2](https://www.g2.com/products/biller-genie); 2.33 from 3 on its [Xero App Store](https://apps.xero.com/us/app/biller-genie) listing, where one reviewer reports a duplicate-charge sync fault worth about $25,000

**Awards:** Inc. 5000 number 259, 2024

**Runs on:** QuickBooks Online through a two-way sync, QuickBooks Desktop through a separate connector, Xero, AccountingSuite, and more than 20 US payment gateways

**Late fees and interest:** Yes, through a Late Fee Manager add-on. An invoice is not treated as late until it is 30 days past due, then charges recur on a 30-day schedule and post to a finance charge account. There is no interest calculation and nothing varies by customer

**Does best:** Surcharging and dual pricing with their own checkout flows, with the fee reconciled back to the ledger automatically

Biller Genie is a payments product with receivables automation attached, and the price says so out loud. The subscription is small and the vendor’s return grows with the value of the invoices it settles for you, which is a merchant-services model rather than a software one.

What the money buys is a whole billing loop. Invoices are raised and delivered from the accounting file, six reminder types run from upcoming payment through to upcoming late fee, paper mail goes out as an option, and the customer pays in a branded portal with autopay, per-customer thresholds and bulk invoice grouping. Behind that sit more than 20 US gateways, surcharging and dual pricing with dedicated checkout flows, a virtual terminal and check capture.

The condition attached is that processing runs through Biller Genie’s own merchant services, which is how the half percent is earned. A business that is happy with its current processor is being asked to move it, and the card and ACH rates on the far side of that move belong in the price comparison as much as the subscription line does.

Instalment plans follow the same logic as the rest of it: the customer requests them through the portal and the merchant approves or rejects each request, rather than the finance team building a schedule up front.

**Limitations with Biller Genie.** The percentage is levied on money collected rather than on work done, so a strong month costs more than a weak one and the climb stops only at the $1,500 cap, reached at $300,000 collected. Reminders run on one cadence for the whole account, with no way to treat a difficult customer differently from an easy one. SMS does not exist as a channel, and every paper reminder is billed individually. The late fee waits until day 30 and has no interest calculation behind it. Processing has to move to the vendor’s own merchant services, so the card and ACH rates arrive with the software. Its three review scores disagree with one another, the Capterra figure sitting far above the G2 and Xero App Store ones, and the lowest of the three carries a report of duplicated charges worth about $25,000.

## 2. Upflow

Best for finance teams that manage collections by metric, quoted in ARR bands from under $10m to $50m and above

### What is it best for?

For a finance team that will accept a quote-only vendor because the reporting is the reason it is buying, on Xero, QuickBooks Online, NetSuite or Sage Intacct.

**Fits:** B2B finance teams that manage by metric, quoted in ARR bands: under $10m, $10m to $50m, and $50m and above

**Regions:** United States and Europe. Founded in Paris in late 2018, head office now in New York, with around 500 customers in more than 30 countries

**Entry cost:** Not published. Upflow prints no figure on any tier and quotes by ARR band. The free Discover tier is analytics only, has to be arranged through sales, and the vendor states it is not a trial. Grow was last verified at $440/mo and Scale at $880/mo. As at August 2026, verify current pricing

**Rated:** 4.8 from 233 reviews on [G2](https://www.g2.com/products/upflow-upflow/reviews), latest June 2026; 4.5 from 15 on [Capterra](https://www.capterra.com/p/193097/Upflow); 5.0 from 1 on its [Xero App Store listing](https://apps.xero.com/us/app/upflow)

**Awards:** None found

**Runs on:** Xero, QuickBooks Online, NetSuite, Sage Intacct, Stripe Billing, Chargebee and Zuora, with a public API

**Late fees and interest:** No, via your ERP only. Upflow's own documentation points the job back to the ERP, and there is no native calculation

**Does best:** Collections analytics, with countback DSO against best possible DSO, collection effectiveness and an at-risk rate above 90 days

Upflow is the opposite kind of purchase in every way that matters to a small buyer. No figure is printed on any tier, quotes are set by ARR band, and even the free analytics tier is gated behind a sales conversation, so the cheapest way to find out what it costs is to spend an hour on a call.

What that buys is the measurement layer, and it is the deeper half of this comparison: countback DSO set against best possible DSO, collection effectiveness, at-risk balances above 90 days, aging and billing-cohort cash forecasting, on dashboards filtered by workflow, country or account manager and scheduled out by email.

The chasing is a multi-step workflow rather than one cadence, sequencing email, SMS, letter, call and task steps against invoice age, customer behavior and risk profile, with a branded portal where the customer pays, disputes or sets a promise to pay. The AI work sits in cash application: payments matched to invoices with suggestions and rules, promises detected from replies, dispute signals surfaced.

**Limitations with Upflow.** No native late fees, so any fee goes back to your ERP, and there is no interest calculation anywhere. No payment plans, only customer-initiated part payments and promises to pay. Statement generation is not documented. Automatic actions fire once a day and on business days only. Sending through your own SMTP disables open and click tracking, and the QuickBooks link polls every five minutes with payments landing in Undeposited Funds for manual reconciliation. No price is published at any tier, so the entry cost cannot be established without a sales conversation.

## The crossover: what you have to collect before Biller Genie costs more

One published rate against one last-verified quote. The arithmetic below is the only way to make them comparable, and it is arithmetic rather than a vendor claim.

Biller Genie is $49.95 plus 0.50% of the value collected. Upflow’s Grow tier was last verified at $440 a month and Scale at $880. The Biller Genie line crosses Grow at about $78,000 collected in a month, and crosses Scale at about $166,000.

On $80,000 collected in a month, Biller Genie costs $449.95 and Upflow’s last verified Grow price is $440.00, so Upflow is $9.95 a month cheaper, or $119.40 a year.

Worked example. On $80,000 collected in a month, Biller Genie costs $449.95 and Upflow's last verified Grow price is $440.00, so Upflow is $9.95 a month cheaper, or $119.40 a year. The page carries an interactive calculator for other amounts.

The first line is $49.95 plus half a percent of the value collected, and the percentage stops at $1,500 a month once $300,000 has been collected. Upflow publishes no price at any tier; $440 a month for Grow and $880 for Scale are last-verified figures, not published ones, so treat the Upflow line as an estimate. Neither line includes what the card processing itself costs. Pricing as at August 2026; verify current pricing before you use these numbers.

Below the crossover Biller Genie is cheaper, and it is very much cheaper for a business collecting a modest amount, because the fixed part of its price is $49.95 and the percentage is small. Above the crossover the percentage keeps climbing until $300,000 collected in a month, where the cap lands at $1,500. From there Biller Genie’s price is flat and Upflow’s is whatever the band says it is.

What sits on each side of that crossing is not the same product, which is the reason to run the numbers rather than pick the lower line. Under it you are buying invoicing, chasing, a late fee and a card and ACH stack. Over it you are buying measurement, and the fee and the payment rails come from somewhere else.

Card processing is the part neither column shows. Biller Genie requires processing through its own merchant stack, so its card and ACH rates are part of the decision as much as the subscription is. Upflow takes ACH, cards and direct debit through the portal as a Stripe partner, so those rates come from the processor you already use.

Two phrases in the table above carry a fixed meaning where a price should be. “Not published” means the vendor prints no figure anywhere public. “Not verified” means a capability could not be confirmed from the vendor’s own materials. A figure that came from a third party rather than from the vendor is labelled last verified, with the month it was read.

## What Upflow’s free Discover tier is, and is not

A free tier from a vendor that publishes no price draws a lot of attention, so it is worth being exact about what it does and what it does not do.

Discover shows you your own collections numbers: countback DSO against best possible DSO, collection effectiveness, at-risk balances, aging and benchmarking. It runs no collection automation of any kind, so it sends nothing to anybody and chases nobody.

It is not a trial, and Upflow says so itself. A trial is the paid product with a clock on it. Discover is a permanent, narrower product, so nothing you configure inside it is chasing that will switch on when you upgrade.

It is also not self-serve. Access is arranged through a salesperson, which means the free tier still costs a discovery call and puts you into the pipeline for the paid ones.

What it is genuinely good for is one job: establishing what your collections performance actually is before deciding whether the problem is worth software at all. A business that runs Discover for a quarter and finds its countback DSO is three days off best possible has learned something more useful than either product on this page would have sold it.

Biller Genie has no free tier to compare it with. What it has instead is no contract and cancellation at any time, which is a different kind of low commitment: you pay $49.95 and the percentage for the month you used it, and stop.

## A fee at 30 days, or no fee at all

Biller Genie applies a late fee through an add-on, on one global rule, and treats nothing as late until it is 30 days past due. Upflow applies none inside the product. Neither one calculates interest.

In the United States a late fee is a term of your contract rather than an entitlement in law, so the rate and the trigger are yours to set within what state law allows. That makes the grain of the software the whole question: how soon a fee can fire, how often it repeats, and whether it can differ between one customer and another.

Biller Genie’s Late Fee Manager is switched on per account. The merchant sets the schedule, the frequency, the amount and the terms shown to the customer, and the charge books to a finance charge account in the ledger. Nothing is treated as late until day 30, and from then the fee recurs every 30 days and stacks.

The 30-day floor is worth testing against your own aged debtors before the feature is counted as a reason to buy. Xero Small Business Insights puts the average US invoice at 8.3 days past due when it finally settles, so a mechanism that cannot fire until day 30 never reaches most of what a small business would call a late invoice. It reaches the accounts that were going to be difficult anyway.

Upflow documents the job in the ERP instead, in a NetSuite article, so the fee is raised where the ledger lives and Upflow reports on what happens next. For a team on NetSuite that is a workable split. For a team on Xero or QuickBooks Online it means the fee is manual.

**Biller Genie:** A charge, not interest. A single rule covers the account, the first charge lands at day 30, and it repeats every 30 days from there. Whether the amount can be a flat sum or a percentage is undocumented, and it is the same for every customer either way.

**Upflow:** Nothing native. The documentation routes late fees to the ERP, so the charge is created there and Upflow measures what follows rather than causing it.

Instalments belong here rather than in a section of their own, because they follow the same pattern. A Biller Genie plan is requested by the customer through the portal and approved by the merchant, so the money has dates against it. Upflow has no plans at all: only a promise to pay, detected automatically from the customer’s reply since December 2025, and ad-hoc partial payments allowed in the portal since August 2025. Both record an intention and leave the follow-up with a person.

## Common questions

What buyers ask when a published rate and an unpublished quote end up on the same shortlist: where the two lines cross, what the free tier includes, and which product charges anybody for being late.

### Is Biller Genie or Upflow better?

Neither is better outright, because they solve different halves of the job. Biller Genie sends the invoice, chases it, charges a late fee and takes the card or ACH payment, at $49.95 a month plus 0.50% of invoices collected. Upflow measures collections, applies no fee and publishes no price. A small business that wants to get paid picks Biller Genie; a finance team that wants to manage by metric picks Upflow.

### How much do Biller Genie and Upflow cost?

Biller Genie has one plan: $49.95 a month, plus 0.50% of what it collects for you, with that percentage capped at $1,500. ACH and paper mail are billed separately. Upflow publishes no price on any tier and quotes by ARR band; Grow was last verified at $440 a month and Scale at $880. Both were read in August 2026; check the current rate before you budget from it.

### At what point does Biller Genie cost more than Upflow?

Against Upflow’s last verified Grow price of $440 a month, Biller Genie passes it at about $78,000 collected in a month, and passes the $880 Scale figure at about $166,000. Below that Biller Genie is cheaper, and the gap is widest for a business collecting very little. The percentage stops growing at $1,500 a month, which is reached at $300,000 collected.

### Do Biller Genie and Upflow apply late fees?

Biller Genie does, through the Late Fee Manager add-on. Nothing counts as late until day 30, and from there the charge repeats every 30 days under a single rule covering every customer. Upflow does not: its documentation points late fees back to your ERP, and there is no native calculation in the product.

### Is Upflow’s free plan a trial?

No. The Discover tier is analytics and benchmarking only, with no collection automation, and Upflow states it is not a trial. It also has to be arranged through sales rather than signed up for, so it is a way to see your own numbers rather than a way to test the chasing.

### Do Biller Genie and Upflow send SMS reminders?

Upflow does, as one step type in a workflow alongside email and letter. Biller Genie does not publish an SMS channel at all: it sends email and, as a paid add-on, paper mail.

### Which ledgers does each one reach?

QuickBooks Desktop is Biller Genie only, through a separate connector, and Upflow lists no Desktop route. On QuickBooks Online both connect, with Biller Genie syncing two ways through webhooks and Upflow pulling one way on a five-minute poll, landing payments in Undeposited Funds and capping custom fields at three text-only fields. Both hold Xero App Store listings. AccountingSuite is Biller Genie only; NetSuite, Sage Intacct, Stripe Billing, Chargebee and Zuora are Upflow only.

## How these two prices were established

One of these figures came from the vendor and one could not, which is why they are labelled differently everywhere they appear above.

Biller Genie prints its price, so its numbers were read straight off the vendor’s own pricing page in August 2026: $49.95 a month, 0.50% of invoices collected, a $1,500 cap, ACH at $0.50 a transaction with a $20 monthly minimum and a $25 setup fee, and paper mail at $1.50 a reminder plus $0.25 an extra page. The same page shows the plan was consolidated out of three older tiers at $19.95, $49.95 and $299.95, which carried percentages from 1.00% down to 0.25%.

Upflow prints nothing, so its figures could not come from the vendor. The $440 Grow and $880 Scale rates are third-party figures, last verified in August 2026, and they are labelled as such every time they appear rather than being presented as prices. Where a number could not be established at all, the cell says so instead of estimating one.

Ratings were read from Capterra, G2 and the Xero App Store with the count and the platform attached to each. Biller Genie’s three scores disagree sharply, at 4.8 from 26, 3.0 from 4 and 2.33 from 3, and the lowest of them carries a reviewer’s report of a duplicate-charge sync fault worth about $25,000. All three are printed rather than averaged, because the average would hide the thing worth knowing.

Neither company was shown this page before it went up, and neither paid for its place on it.
