Zoho Invoice is a free cloud invoicing app with a client portal, recurring billing, and online payment collection. BulkyGen is an offline Windows app built for one job — turning a spreadsheet of clients into a batch of branded PDF invoices in one run. If you need ongoing client-facing billing infrastructure, Zoho is the better fit; if your invoicing already starts life as a spreadsheet, this page explains why BulkyGen might save you more time.
What Zoho Invoice is for
Zoho Invoice is built for businesses that want invoicing tied into a wider billing relationship: a portal where clients log in to view and pay invoices, automatic recurring invoices for subscription billing, payment reminders, and integration with the rest of the Zoho suite (accounting, CRM, and more). It runs in the cloud, so your data lives on Zoho's servers and is reachable from any device.
What BulkyGen is for
BulkyGen doesn't try to be a billing platform. It does one thing: you keep your client list and line items in a spreadsheet, you upload it, and it produces a folder of finished PDF invoices — one per client — in a single run. No portal, no recurring schedule, no client accounts. You generate, you send the PDFs yourself (email, WhatsApp, wherever you already send invoices), and you're done.
Where Zoho Invoice genuinely wins
- A client portal. Customers can log in, see invoice history, and pay online — BulkyGen has no equivalent.
- Recurring billing. Zoho can automatically issue and send an invoice on a schedule. BulkyGen has no recurring engine; every run is something you trigger.
- Online payment collection. Cards and other payment methods can be accepted directly against a Zoho invoice.
- Access from anywhere. Cloud-based, so it's usable from a phone or any browser, not just one Windows PC.
Where BulkyGen genuinely wins
- Bulk from a spreadsheet you already have. Zoho's bulk import exists, but BulkyGen is built around spreadsheet-in, PDFs-out as the core workflow, with fuzzy column matching so your existing export usually works without reshaping it first.
- Fully offline. Your customer list and revenue never leave your machine — no account, no cloud storage of your billing data.
- A one-time licence option. Zoho Invoice's free plan caps how many invoices or contacts you can have before you're pushed to a paid tier; BulkyGen offers a lifetime licence with no recurring charge at all.
- No client accounts to manage. If you don't want or need a portal, that's less surface area, not a missing feature.
Where BulkyGen doesn't win
To be direct about it:
- No recurring billing — every batch is manual.
- No client portal and no online payment collection built in.
- Windows only, one device's local install — not accessible from your phone or another computer without activating a second device (device limits apply per licence, see pricing).
- No accounting-suite features — no expense tracking, no reports, no CRM.
Pricing, honestly

BulkyGen: free forever for up to 7 invoices a day, a 7-day bulk trial, then $9/month, $90/year, or $249 once for a lifetime licence — full detail on pricing.
Which one should you use?
If clients need to log in and pay you online, or you bill on a recurring schedule, Zoho Invoice covers ground BulkyGen doesn't try to. If your invoicing is really "here's a spreadsheet of who owes what, turn it into PDFs I can send," preparing your spreadsheet for a bulk run is a shorter path than setting up a cloud account you don't otherwise need.
