I tried OpenClaw to automate my invoicing — here is what happened and what I used instead

For two years, I sent invoices using Excel templates. Every month: draft invoice, save as PDF, email client, set reminder to chase payment. It worked. Barely.

The friction adds up. You forget to send one invoice and suddenly cash flow is off. You miss following up on an overdue payment and two months later you're having an awkward conversation trying to remember what the project was even for.

So when I heard about OpenClaw — an open source invoicing tool that promised AI automation — I figured I'd give it a real try.

What OpenClaw promises

OpenClaw calls itself "the open source Stripe for invoicing." The pitch looked good:

• Self-hosted or cloud
• AI-generated invoice templates
• Automated payment reminders
• Multi-currency support
• Integrates with Xero, QuickBooks, Stripe
• No monthly fees if you self-host

For someone trying to avoid yet another S$29/month SaaS subscription, this sounded perfect.

Setup was fine

I went with cloud hosting because I didn't want to deal with servers. Sign-up took maybe 10 minutes. Email, password, company details. The onboarding wizard asked for my UEN, GST status, payment terms, bank details.

Smooth enough.

Where it fell apart

The "AI templates" weren't AI

OpenClaw's AI-generated templates are... not that. What you actually get is a template library where you pick a design and then manually customize every field yourself.

The AI part generates some boilerplate payment terms text. But it's generic and often wrong for Singapore. The default mentioned "ACH transfers" — which is a US thing — instead of PayNow or FAST, which is what businesses here actually use.

Worse, customizing the template means editing raw HTML in a code editor. If you're not technical, you're stuck.

No GST compliance

This was the dealbreaker.

Singapore businesses registered for GST have to issue tax invoices with specific mandatory fields. IRAS doesn't mess around with this. You need:

• Supplier name, address, GST number
• Customer name and address
• Tax invoice serial number
• Date of supply
• Description of goods or services
• Total excluding GST
• GST amount charged
• Total including GST

OpenClaw has a "tax" field. That's it. It doesn't enforce any of this. I had to manually verify every single invoice to make sure I wasn't going to get flagged by IRAS. That's not automation.

Payment tracking was still manual

I wanted automated payment tracking. OpenClaw integrates with Stripe, which works great... if your clients pay by card.

In Singapore B2B? Most payments are bank transfers. PayNow, FAST, GIRO. OpenClaw's answer to this is: upload a CSV from your bank and manually match transactions to invoices.

I was doing that in Excel already. No improvement.

Emails went to spam

OpenClaw sends automated payment reminders using shared email infrastructure. After a week, I realized clients weren't getting them. Checked spam folders — yep, there they were.

The sending domain had a bad reputation score from other users.

OpenClaw's suggested fix: set up your own SMTP server and configure SPF/DKIM records yourself. For a tool that's supposed to be plug-and-play, this felt like a bait-and-switch.

What I learned

OpenClaw isn't a bad product. It's just not built for Singapore businesses.

It works well if you're in the US or EU, you're comfortable editing code, and your clients pay by card. If that's you, it's probably fine.

If you need GST compliance, bank transfer tracking, and you don't want to spend a weekend configuring email DNS records, OpenClaw will create more work than it saves.

Why I switched to Claify

Three weeks in, I started looking for Singapore-specific tools. Found Claify.

Claify is built for Singapore SMEs. Here's what actually worked:

GST compliance out of the box

Claify's templates come with all the mandatory GST fields pre-configured. You enter your GST number once during setup. Every invoice after that is automatically IRAS-compliant.

No code. No manual checking. It just works.

Actual bank transfer tracking

Claify integrates directly with DBS, OCBC, UOB, and PayNow. When a client pays via bank transfer, the system detects it and matches it to the right invoice automatically. The status updates on its own.

This saves me about 2 hours a month. Maybe more if I'm being honest.

Payment reminders that land in inboxes

Claify's reminders:

• 3 days before due date (friendly nudge)
• On due date (standard followup)
• 7 days overdue (firmer, with escalation options)

The emails send from your own domain. Claify walks you through DNS setup once — takes maybe 5 minutes — and after that, delivery rates are solid. Haven't had a single email go to spam yet.

Recurring invoices with less babysitting

For retainer clients, Claify auto-generates and sends invoices on whatever schedule you set. Monthly, quarterly, annually.

OpenClaw technically has this too. But Claify adds stuff that actually matters:

• Auto-adjusts pricing if you bill hourly and hours change
• Client portal where they can view past invoices themselves
• Auto-pauses if a client reports a lost card (so you don't get hit with failed charge fees)

What it costs

Free for solopreneurs (up to 20 invoices/month). Paid plans start at S$29/month after that.

I'm still on free. If I ever hit 20 invoices in a month, I'll happily pay S$29 just for the reconciliation time saved.

Bottom line

If you're technical, US-based, and clients pay by card: OpenClaw is solid.

If you're a Singapore business that needs GST compliance and bank transfer tracking without spending your weekend on server config: use Claify.

Biggest lesson for me: "open source" and "free" don't mean "better" if the tool wasn't built for how your country actually does business.

Claify is free for solopreneurs. Paid plans for growing businesses start at S$29/month.
