Bookkeeping and accounts-payable work is exactly the kind of repetitive, rules-based task AI is actually good at right now: read a document, extract the numbers, match them to the right category or invoice, flag anything unusual for a human to check. A new wave of tools automates pieces of that pipeline — from full bookkeeping with a human accountant still reviewing the books, to invoice-to-cash automation, to just turning a stack of PDF invoices into a clean spreadsheet. This guide covers 6 real, currently-active tools so you can see which slice of the accounting workload each one actually handles, and what it costs.
The short version
If you want AI to handle your actual bookkeeping — categorizing transactions, reconciling accounts — with a human accountant still reviewing before anything posts, Puzzle is built specifically for that. If you're a freelancer or small business that wants invoicing, expenses and basic accounting bundled with a genuinely useful free tier, Frihet is the most accessible, especially in Spain. If your pain point is chasing vendor invoices or getting paid, Routable and Peakflo both automate accounts-payable/receivable at volume — Routable leans API-first, Peakflo leans multi-channel human contact (including WhatsApp). ChatFin goes furthest by automating the whole month-end close inside your existing ERP, aimed at larger finance teams. And if all you need is to turn a pile of PDF invoices into an Excel file without retyping anything, Invoscope does exactly that and nothing more.
Puzzle
Puzzle is bookkeeping software that has an AI do the tedious reconciliation work overnight — up to 98% automated, according to the company — and shows you your real cash position, burn rate and runway the next morning, with an actual accountant still able to review and approve before anything gets posted.
For who: startups, small businesses and accounting firms that want automated bookkeeping with real-time financial visibility, not a black-box AI with no human check.
Price: Starter $25-30/mo, Core $30-36/mo, Complete $50-60/mo, Scale $150+/mo — 20% off annual billing, 14-day free trial, no card required.
Forces: up to 98% bookkeeping automation without writing manual rules, real-time visibility into cash, burn rate and runway, human accountant review before anything is finalized (not a fully blind AI), and a no-card 14-day trial.
Limites: it's bookkeeping only, not invoicing or pricing/CPQ, so you'll still need a separate tool for that; complex accounting needs push you into the $50-150+/mo tiers; a human review step means it's not literally 100% hands-off; and it's less useful if you already have a dedicated in-house accounting team.
Verdict: the most complete "AI bookkeeper with a human safety net" option here — a good fit if you've outgrown spreadsheets but aren't ready to hire a full-time accountant.
Frihet
Frihet bundles invoicing, expense tracking (with OCR), bookkeeping and CRM into one subscription, built so freelancers and small businesses don't need three separate tools for billing and books — with native Spanish tax compliance (VeriFactu, TicketBAI) baked in.
For who: freelancers, small businesses, agencies and accounting firms — especially in Spain and other Spanish-speaking markets where the built-in tax compliance actually matters.
Price: free up to 999 invoices/month; Pro €9/mo; Premium €29/mo (adds an AI copilot and advanced bookkeeping).
Forces: invoicing, OCR-based expense capture, bookkeeping and CRM in a single subscription, native Spanish tax compliance, double-entry bookkeeping across 170+ currencies and 96 countries, and an open-source MCP server for connecting AI assistants.
Limites: the flagship tax-compliance advantage is Spain-specific and irrelevant elsewhere, the company's founding date and track record aren't public, generalist competitors like Wave may be enough if you don't need the Spanish compliance angle, and the AI copilot is capped at 100 messages/month even on the priciest plan.
Verdict: an easy recommendation for freelancers and small businesses in Spanish-speaking markets — outside that market, judge it purely on the invoicing+bookkeeping bundle, not the tax angle.
Routable
Routable is an accounts-payable automation and mass-payout platform with a developer API: AI reads and codes incoming invoices automatically, then handles vendor payments across 220+ countries and 140+ currencies, plus automated tax-form generation (1099s and similar).
For who: finance teams, controllers and accountants at growth-stage companies, plus marketplaces, gig-economy platforms, insurance, real estate and logistics businesses that pay out many vendors.
Price: Enterprise, custom pricing — no public tiers, requires a sales conversation.
Forces: AI invoice OCR with automatic coding claimed to cut manual AP work by around 80%, very wide country/currency coverage for global payouts, automated tax-form generation, and solid integrations with NetSuite, QuickBooks, Xero and Sage.
Limites: no public pricing at all, it's a heavier platform than you need if all you want is a payout API, and the value only really shows up once your vendor-payment volume is genuinely high.
Verdict: worth a sales call if vendor payouts at real volume are the bottleneck — overkill if you're paying a handful of vendors a month.
Peakflo
Peakflo automates the back-and-forth of getting invoices paid and bills approved using AI agents instead of a finance team chasing emails — and it can chase over WhatsApp, Slack or voice, not just email.
For who: finance and back-office teams at mid-size to large companies with meaningful AP/AR volume, especially in markets where WhatsApp is a normal business channel.
Price: Enterprise, custom pricing only — requires a sales consultation, no self-serve tier.
Forces: multi-channel agent contact (email, WhatsApp, Slack, voice) rather than email-only, one-click integrations into major ERPs (Xero, NetSuite, SAP, Dynamics), 100+ customers including recognizable brands, and Y Combinator backing with $4.1M in seed funding.
Limites: entirely custom/enterprise pricing with no self-serve tier to test cheaply, vendor efficiency claims (like "40% cost reduction") are self-reported and unverified, it competes in a crowded niche of similar agentic AP/AR tools, and it's built for real transaction volume rather than small businesses.
Verdict: worth comparing directly against Routable before committing — both solve AP/AR automation, but Peakflo's multi-channel contact and Southeast Asia presence set it apart.
ChatFin
ChatFin is an agentic AI platform that automates finance workflows like month-end close, accounts payable and accounts receivable directly inside your existing ERP — with native integrations into 16+ ERPs so you're not exporting and re-importing CSVs.
For who: finance teams — controllers, FP&A, CFOs — at mid-to-large organizations already running a major ERP.
Price: Enterprise, custom pricing via demo; marketing materials claim $100K+ in annual savings and a 4-8 month break-even versus buying separate point solutions.
Forces: native integration with 16+ ERPs with no CSV exports needed, automates the full spend lifecycle rather than a single step, SOC 2 Type II and ISO 27001 certified, and keeps a human-in-the-loop for approvals instead of fully autonomous posting.
Limites: no public pricing at all, no free tier so it's clearly not aimed at small businesses, and its marketing leans heavily on Fortune 500 case studies with less proof for mid-market companies.
Verdict: the most ambitious tool on this list — a fit if you want one platform automating the entire close and AP/AR cycle inside an existing ERP, not for anyone still doing books in a spreadsheet.
Invoscope
Invoscope does one specific thing: feed it a pile of invoice PDFs and it hands back a clean Excel spreadsheet a few seconds later, using AI extraction that works even when invoices don't share a common template — no retyping, no copy-pasting numbers by hand.
For who: small finance/admin teams that receive PDF invoices from many different vendors and want to stop re-typing them manually.
Price: Freemium — free for up to 10 invoices/month, no card required; pricing beyond that isn't published.
Forces: handles invoices without a shared template thanks to AI extraction, a real free tier (10 invoices/month, no card) to test accuracy before paying, one-click Excel export, and support for custom templates on recurring invoices.
Limites: pricing beyond the free tier isn't published, there's no visible accounting-software integration (QuickBooks, Xero), it remains a PDF-to-Excel converter rather than a full accounts-payable suite, and the company has no verifiable public track record or launch date.
Verdict: the right pick if your actual problem is small and specific — killing manual invoice data entry — not if you need the fuller AP workflow that Routable or Peakflo provide.
Side-by-side

Which one should you actually pick?
Match the tool to the actual bottleneck, not the category label. If your books themselves are the mess, Puzzle is the most complete answer with a human accountant still in the loop. If you're a freelancer juggling invoicing and basic bookkeeping on your own, Frihet's free tier covers a lot before you'd need to pay anything. If the problem is specifically vendor invoices piling up or customers paying late, Routable and Peakflo are built for that — compare both since they're direct competitors. Larger finance teams already running an ERP and wanting the whole month-end close automated should start with ChatFin. And if you're overpaying in complexity for a problem that's really just "stop retyping PDF invoices," Invoscope's free tier will tell you in minutes whether AI extraction is accurate enough for your vendors.
