Gennai vs WellyBox: Honest Comparison for Small Businesses (2026)

If you have searched for a way to stop manually processing documents from your inbox, you have probably encountered both Gennai and WellyBox. Both tools connect to Gmail and Outlook and pull documents automatically. Both use AI and OCR to extract data. Both export to accounting software.

But they are not interchangeable. WellyBox was built to solve the expense receipt problem: capturing what you spend, organizing it for tax time, and generating expense reports. Gennai was built to solve the supplier invoice problem: capturing what your suppliers bill you, extracting structured data, and pushing it to your accounting platform for accounts payable.

Those are related but distinct workflows. This comparison lays out exactly what each tool does, where each one is stronger, and which one fits your situation.

A note on this comparison: This article is written by Gennai. We have done our best to represent WellyBox accurately using their public pricing page, their official feature documentation, and independent user reviews from G2, Capterra, and GetApp. Where WellyBox is the better choice, we say so. All pricing and feature data was verified in April 2026.

1. The core difference in one sentence

WellyBox — Expense and receipt management for freelancers and small teams who need to track their own spending, organize receipts, and generate expense reports.

Gennai — Supplier invoice capture for small businesses and accounting teams who need to collect, extract, and export inbound supplier invoices to Xero, QuickBooks, or Holded without manual data entry.

This distinction matters more than any individual feature difference. If you are a freelancer tracking your own coffee receipts and travel expenses, WellyBox is built for you. If you run a business that receives supplier invoices by email and needs them in Xero or QuickBooks without manual re-entry, Gennai is built for you.

2. What each tool is actually built for

WellyBox

WellyBox describes itself as an AI-powered virtual assistant for expense and receipt management. Its primary use case is collecting receipts from your own spending: supplier emails you receive, online purchases from platforms like Amazon or eBay (beta feature), and paper receipts scanned via WhatsApp. The extracted data feeds expense reports and tax summaries. The target user is a freelancer, solopreneur, or small team who wants to stop losing receipts at tax time.

WellyBox connects to Gmail, Outlook, and other IMAP providers. It has a WhatsApp chatbot for scanning paper receipts. It exports to QuickBooks, Xero, FreshBooks, Google Drive, and Excel. No mobile app is available; it runs as a web application. The platform does not offer an API.

Gennai

Gennai is built around a single, specific workflow: inbound supplier invoices arrive in your Gmail or Outlook inbox as PDF attachments, AI extracts the structured data (vendor, amount, date, tax, invoice number, line items), and the records are pushed directly to Xero, QuickBooks Online, Holded, Google Drive, OneDrive, or Google Sheets. The target user is a small business owner, finance manager, or accountant who manages accounts payable for one or several companies.

Beyond email, Gennai also captures invoices forwarded through WhatsApp and Telegram, as well as manually uploaded PDFs. External accountant access is built into every plan, letting accountants log in with their own credentials to review, search, and export invoices without touching your inbox. The Business plan includes API access.

4. Pricing comparison

One pricing difference worth noting: WellyBox's Basic plan is only available with annual billing, which means a minimum commitment of $228 upfront to get started at entry level. Gennai's Starter plan is available monthly at $12 with no lock-in, or annually with a 25% discount. Gennai also has a permanent free plan for low-volume users.

5. Where WellyBox wins

WellyBox is the right choice in specific situations, and it is worth being clear about them.

Expense reporting and receipt organization

If your primary need is tracking your own spending, categorizing expenses by type, and generating monthly or quarterly expense reports for tax purposes, WellyBox is built exactly for that workflow. Gennai does not produce expense reports.

FreshBooks users

WellyBox integrates with FreshBooks. Gennai does not. If FreshBooks is your accounting platform, WellyBox has a direct path to it.

eBay portal collection (beta)

WellyBox is building a feature to pull receipts directly from online shopping portals (Amazon and eBay). Gennai also covers Amazon via its Chrome extension, which surfaces import buttons on Amazon order history pages. But if you need eBay specifically, WellyBox has a direct portal integration that Gennai does not offer.

Freelancers focused on personal expense tracking

If you are a sole trader with a simple need to capture and organize what you spend, WellyBox's interface is clean and easy to navigate. Gennai is oriented toward managing invoices you receive from suppliers, not personal expenses.

6. Where Gennai wins

Gennai is built around one problem: getting supplier invoices from your inbox into your accounting platform without manual work. If that is your workflow, the differences add up quickly.

Holded integration

Gennai is one of the few tools in this category with a native Holded integration. WellyBox does not support Holded. For businesses using Holded as their ERP, this alone is the deciding factor.

Line item extraction

Gennai extracts line items from invoices, not just header-level data. This matters for businesses that need to reconcile individual product lines, split costs across departments, or match invoice lines against purchase orders. WellyBox extracts amount, date, and vendor but does not extract line items.

Telegram capture

Gennai accepts invoices forwarded through Telegram in addition to WhatsApp. WellyBox supports WhatsApp only. For teams that communicate through Telegram, this removes an extra step.

Free permanent plan

Gennai offers a genuine free plan: 10 invoices per month, 2 email accounts, no credit card required. WellyBox offers a free trial but no permanent free tier. For very small operations or businesses testing the workflow before committing, this matters.

Monthly billing available on all plans

Every Gennai plan can be paid monthly with no lock-in. WellyBox's entry-level Basic plan is available on annual billing only, requiring an upfront payment of $228 to get started.

CASA Tier 2 security certification

Gennai holds a CASA Tier 2 security certification from TAC Security, an independent audit of application security controls relevant to OAuth-connected tools. WellyBox does not list an equivalent certification.

7. Who should choose which

The simplest way to frame the choice: if your problem is "I lose my expense receipts and struggle at tax time," WellyBox solves that. If your problem is "I receive supplier invoices by email and my accountant still has to type all of them into Xero," Gennai solves that. Most small businesses eventually need both workflows, but they are not the same workflow.
