I run a bootstrapped B2B SaaS company in India.

Like many early-stage companies, our internal processes were stitched together manually.

For invoicing, my cofounder would manually export data, generate invoices, send emails to each client one by one, and then compile a separate sheet for our CA for GST filing. This would take 8-10 hours every single month.

As we scaled, this manual system started to crack - errors crept in, clients said they didn't receive invoices, our CA kept asking for corrections, etc. It was a mess.

So instead of hiring ops people, I built an internal automation stack using Google Sheets + Apps Script + APIs.

Now with one click, it:

• Pulls raw usage data, processes it, and matches it to client records automatically
• Flags new users who aren't in the client database (so nothing falls through the cracks)
• Applies pricing plans & generates a PDF invoice + CSV of usage for each client
• Sends emails via Microsoft Graph API with templatized, professional emails
• Stores generated PDFs & CSVs in organized folders with appropriate file names
• Logs everything — successes, skips, errors — with hyperlinks to every generated document
• Has a one-click resend option if a client claims they didn't get their invoice
• Produces a clean GST calculation sheet for CA, where they just select month & year and get everything they need
• Can be customized for any billing model — subscriptions, retainers, usage-based, whatever

What used to take 8–10 hours now takes ~10 minutes, with near-zero errors.

We’ve used it internally for 3+ months and it’s been rock solid.

I built it for ourselves, but my accountant pointed out that many SMEs have painful manual workflows around billing / reconciliation / reporting / finance ops. He's already referring a few of his clients to me - which is why I'm posting this.

I'm taking on a few clients to help them set up such automation for their business. Initial setup takes about a week depending on complexity. You own it fully after that.

One-time fee. No subscriptions. 30 days of support included.

If your billing process still involves manual work, copy-pasting, or your CA chasing you for clean data — DM me or drop a comment. Happy to understand your workflow and tell you honestly if this can help.

(We're a bootstrapped SaaS ourselves — this isn't a product pitch, it's a founder who solved his own problem offering to solve yours.)
