BIR-Compliant Invoicing and a Client Portal, Built Into Your Business Website
Every other invoicing software for small business in the Philippines is self-serve — you sign up and configure it yourself, with no client portal and no connection to your website. KAIZO is the only Metro Manila provider that builds a real business website, a BIR-compliant invoicing system, and a client portal into one managed package, and runs it for you.
THE PROBLEM
Sound familiar?
You’re invoicing clients over Viber or text — no TIN on the invoice, no sequential numbering, nothing you could hand a BIR examiner.
A client emails asking “can I get a copy of my invoice again?” — and you have to go dig for it.
You’re chasing late payments manually, texting the same “just following up” message every few days.
Your accounting tool and your website live in two different worlds and never talk to each other.

features
Everything you need to invoice, get paid, and stay organized
Bundle — Website + Client Portal
Every invoice carries your business TIN and RDO code, with the correct VAT-registered or Non-VAT boilerplate line — the exact wording BIR requires on a compliant invoice generator.
- Correct VAT and Non-VAT invoice format, with your TIN and RDO code
- Handles VATable, Zero-Rated, and VAT-Exempt sales correctly, plus withholding tax (EWT) invoices
- Editable, sequential invoice numbering — you set the prefix and digit padding
- Statutory discounts (Senior Citizen, PWD, Solo Parent) calculated automatically
A portal your clients will actually use
No app to install and no password to reset — clients log in with a one-tap magic link and see everything about their project in one place.
- Passwordless magic-link login — nothing for clients to remember
- Automatic recurring and scheduled invoices, with late fees calculated on overdue balances
- Partial payments close the original invoice and auto-create a new one for the balance — no manual reconciliation
- Clients submit proof of payment and message you directly, per project
Documents that don't live in your inbox
Every project gets its own Google Drive folder automatically, so files stop getting buried in email threads.
- A dedicated Drive folder created automatically for every project
- A private subfolder keeps internal files hidden from the client
- Shared documents show as links right on the project page, for you and your client
Make it yours
Your logo, your brand color, your own words for how your business works — the system adapts to you, not the other way around.
- Your logo, brand color, and email theme throughout
- Rename "Project" to "Job," "Engagement," or whatever you call it — platform-wide
- A "Classic" invoice layout that replicates the pre-printed BIR booklet your clients already know
- CSV export mapped to BIR filing (2550M/2550Q, 2551Q) for your bookkeeper

Comparison
Why not just use self-serve invoicing software, or a plain website?
Self-serve invoicing apps handle compliance but have no client portal and no connection to your website — you configure everything yourself. A plain business website looks good but has no invoicing at all. What you’d otherwise need two vendors for, you get from one managed package.
| Capability | Self-serve invoicing app | Plain business website | KAIZO managed package |
|---|---|---|---|
| BIR-compliant invoice formatting | Yes | No | Yes |
| Client self-service portal | No | No | Yes |
| Business website included | No | Yes | Yes |
| Runs on your own WordPress | No | Yes | Yes |
| One team for setup & support | No | Depends on provider | Yes |
FAQ
Common questions
Is this BIR accredited?
No — and no invoicing software is “BIR Accredited” in that sense. What we build gives you BIR-compliant invoice formatting: correct TIN, RDO code, VAT/Non-VAT boilerplate, and correct handling per sale type. Your business keeps its own BIR registration and Acknowledgement Certificate directly with the BIR. Not tax or legal advice — for compliance questions specific to your business, consult BIR or a Philippine accountant.
Does it handle both VAT and Non-VAT invoice formats?
Yes. The system prints the correct VAT-registered or Non-VAT boilerplate line automatically, and applies the right tax handling for VATable, Zero-Rated, and VAT-Exempt sales — you don’t choose the wording manually.
Can it calculate withholding tax (EWT) on an invoice?
Yes — withholding tax invoicing in the Philippines is supported, so the correct EWT amount is reflected on the invoice when a client withholds tax from your payment.
Can I set up recurring invoices for retainer clients?
Yes. This is a recurring invoice system — invoices go out automatically on a schedule, or you can create scheduled invoices in advance to send on a future date.
Do I still need to use my BIR-printed invoice and send to my clients?
Yes — the system is here to help you speed up invoice processing and collection. You can sync the invoice numbering of this system to your actual printed invoice. The PDF copy can be your client’s e-copy of your printed invoice, assuming they use the same invoice number.
I already have a website — can I add just the invoicing and portal?
Yes — that’s the Portal Only option. It installs standalone on your existing WordPress site; you don’t need a new website to get the invoicing system and client portal.
Do my clients need to create a password for the portal?
No. Clients log in with a passwordless magic link sent to their email — there’s no password for them to create, remember, or reset.
Can I keep the paper-booklet invoice look my clients are used to?
Yes — the “Classic” layout replicates a pre-printed BIR service-invoice booklet, with payment fields that fill in automatically from actual payments instead of by hand.
Is my website or data locked to KAIZO?
No. You own your WordPress installation and everything on it. Nothing is rented or locked to a third-party platform — KAIZO installs, configures, and supports the system for you, but it’s yours.
