I will build custom invoicing and billing software
Cristina Ye
About this gig
Most invoicing tools ask you to change how your business works. I build the system around the process you already have inside your own Google Sheets.
I run a hospitality business myself. Nothing off the shelf matched how we work with suppliers, delivery platforms and the bank, so I built my own invoicing system. It runs every day.
WHAT YOU GET
A working invoicing system in your own Google Sheet
Your layout, your numbering, your tax rules
Invoices generated and stored automatically, no copy-pasting
A short video showing you how to run it
You own the file. No monthly software fee, no lock-in
HOW IT WORKS
1. You tell me what you do by hand today
2. I map your real process (chat or a 20-min call)
3. I build it and test it with your own data
4. I hand it over with instructions
Not sure which package? Message me with what you do by hand today and I'll tell you honestly which one you need or if you don't need me at all.
Monthly support available as an extra.

Languages
Spanish, English, Chinese
I run 2 restaurants in Madrid and build automation for small businesses in Spain — n8n, Claude Code, Google Business Profile.
I built a pipeline that scans Google Maps for local businesses with a visible problem (unanswered reviews, no website, low rating) and turns it into clean lead lists for agencies. It's the same system I use to find my own clients, and the same review-reply automation I run in my own restaurant.
Languages: Spanish (native), Chinese (native), English (fluent). Fast delivery, hand-checked data, no recycled databases.
FAQ
Do I need to know how to code?
No. You get a finished Google Sheet and a video showing how to use it.
Why Google Sheets and not an app?
Because you keep it. It lives in your own Google account, there's no monthly software fee and nothing breaks if you stop working with me.
Will it work with the tools I already use?
Usually yes — spreadsheets, email and most accounting exports. Tell me what you use before ordering and I'll confirm.
What if it doesn't fit my process?
I map your process before building, and revisions are included. Surprises are rare because we agree the scope first.
