What's the best accounts receivable software for a small business in 2026?

Chaser is a UK company, and it's the most complete tool here on channels. The Compact plan already includes 100 text messages and 100 automated phone calls a month. Elsewhere, texts are billed per message or don't exist at all. For a customer who ignores email, a text on the due date often does the job.

Compact costs $259 a month with four users, or 10% less billed annually. Chaser can also add late fees to overdue invoices automatically. If your payment terms allow late fees, having the software apply them takes the awkward personal decision out of it.

The catch is a revenue cap. Compact stops at $5M in annual revenue. Above that, Core costs $779 a month, three times more. A growing business needs to know this before signing. Reviewers say Chaser works best with Xero and is less smooth with other accounting tools. They also say results depend on getting the reminder rules right at setup.

Tip: look at next year's projected revenue, not this year's. If you'll cross $5M within twelve months, get Core priced during the demo.

Upflow's strength is the customer portal. Your customer sees every open invoice, downloads documents and pays by card or ACH. Each payment stops the reminders on its own. If your late payers are mostly people who forget or face friction, this is often the fastest fix.

Seats are unlimited and so are emails. Texts, calls and letters are billed by usage, but Upflow doesn't publish those rates. The entry plan, Starter, covers up to $10M in billed revenue and 40,000 invoices a year. A free Discover plan exists, but it only gives you dashboards, with no follow-up at all.

The catch: you won't know your budget before the demo. And online payment has its own cost: a $390 monthly platform fee, plus 3.5% and $0.30 per card payment, or 0.8% capped at $5 per ACH payment. On a $3,000 invoice paid by card, that's more than $100 in fees. One logistics user also questioned how well it matches bank transfers that pay up to 30 invoices at once.

Tip: push ACH rather than cards on large invoices. Capped at $5, it costs a fraction of the card fee.

Paidnice is the most transparent tool in this ranking. Every plan is on the pricing page, billed month to month with no contract. Essentials costs $69 a month for 150 invoices and two team members. The Pro plans scale by invoice volume, from $99 for 300 invoices to $489 for 2,000, and they include unlimited members.

It connects to Xero, QuickBooks Online and Stripe. Texts cost $0.10 each. If you run more than one company, each extra entity adds $29 a month. That's useful for owners with two or three small businesses under one roof.

The catch: Paidnice is priced by invoice count, so a business with many small invoices climbs the tiers fast. Its pricing page is also inconsistent about what Essentials includes, so confirm the exact feature list before you commit. Customer portal and risk tracking are lighter than Upflow's.

Tip: count your invoices over your three busiest months, not an average month. Pick the tier that covers the peak, since the plan follows your volume.

Billabex works differently. An AI agent writes the follow-ups, adjusts tone and channel to each customer, and hands off to a person when needed. It works in eight languages, English and Spanish included.

Its pricing model suits businesses that bill the same customers again and again. Billabex counts only active customers, meaning those who received at least one email from the agent in the period. Invoice count, amounts, users and connectors don't enter the price. Tiers run from 40 to 250 active customers, but amounts aren't published. It takes no commission on money recovered.

The catch: anything that isn't email runs on prepaid credits. A text costs 1 credit, a tracked letter 6, a registered letter 12. Credits expire after 12 months and aren't refunded. The tool also stays on friendly B2B follow-up: no formal collections. Public reviews are glowing but few, and one user found navigation and search could be better.

Tip: buy credits as you go rather than in a big batch. A pack still unused after a year is lost.

Recovr is a Belgian vendor that covers the longest path. From the Essential plan, it sends reminders from your own domain by email, text, letter and registered mail, in your customer's language and currency. It adds late fees automatically. It gives customers a portal to pay online. And when friendly follow-up fails, it prepares a formal demand and connects you with a legal partner.

An AI agent acts like a credit manager: it suggests the day's actions instead of firing everything off by itself. The Business plan adds an inbox that sorts customer replies, advanced rules, DSO tracking and automated payment plans. AI phone calls are an option.

The catch is budget visibility. No price is published: it's calculated in a demo from your invoice volume. Onboarding is a one-time fee on top of the subscription. Recovr targets businesses with more than 100 invoices a month. Users also criticize its invoicing side, which can't duplicate invoices or create recurring ones. Keep your invoicing software alongside it.

Tip: in the demo, ask for the onboarding price and the second-year price in writing. Those are the two numbers the pricing page leaves out.
