Google Sheets and Apps Script, built to run your business

I build registration and payment systems, automations, text message reminders, dashboards, web apps and integrations on top of Google Sheets. It all runs in your own Google account, with no new software for your team to learn.

    What I build

    Most projects start with one of these. Many end up as two or three working together, like a sign-up form that takes payment and feeds a dashboard.

    1

    Apps Script development

    Custom code that runs inside your Google account and connects Sheets, Gmail, Drive, Calendar and Forms.

     2

    Google Sheets automation

    Take the copy, paste, email and reminder work out of your week.

     3

    Dashboards and reporting

    One screen that shows the numbers you check every day, updated on its own.

     4

    Registration and payment systems

    Sign-ups, waitlists, payments and confirmations, all landing in one sheet you control.

     5

    Web apps and front ends

    A clean form, portal or booking page on top of your sheet, so customers and staff never see the spreadsheet.

     6

    Google Sheets CRM

    Leads, customers, follow-ups and deals in a sheet built around how you actually sell.

     7

    Excel to Google Sheets migration

    Move workbooks, formulas and VBA macros over so they work properly in Google Sheets.

     8

    Spreadsheet repair and speed-up

    Fix broken formulas, slow loading and messy data so the sheet is trustworthy again.

     9

    And more!

    Inventory trackers, job scheduling, invoicing, payroll prep, inspection logs, volunteer sign-ups. If it lives in a spreadsheet, ask me.

    I built these for my own business first

    For six years I ran a local business that took registrations for programs every season. Off-the-shelf software never quite fit how we worked, so I built our registration and payment system on Google Sheets and Apps Script myself.

    Families signed up online, paid by card and got a confirmation. Rosters, balances and reminders took care of themselves. That's the kind of system I build for clients now, and why I care about the details an operator notices.

    Registration and payment systems
    • Sign-upsOnline form with session choices, capacity limits and a waitlist
    • PaymentsCard checkout, matched back to the right family automatically
    • EmailsConfirmations, reminders and balance notices sent on their own
    • RostersA clean list per session for every coach or instructor
    • ReportingEnrollment, revenue and who still owes, on one screen

    A custom sheet or off-the-shelf software?

    Sometimes a subscription app is the right call, and I'll tell you when it is. For a lot of small teams, a well-built sheet is the better fit.

    Custom Google Sheets systemTypical subscription software
    Cost over timeOne project fee. Runs on the Google account you already have.Monthly per-user fees, and some take a percentage of each payment.
    FitBuilt around how you already work, your fields and your steps.You change your process to match the software.
    Your dataIn a sheet you own. Export, filter or share it any time.In their system. Exports can be limited.
    Learning curveYour team already knows Google Sheets.New logins and training for everyone.
    ChangesAdd a column or a step whenever you need one.Wait for the vendor or pay for a higher plan.
    Best forSmall teams, thousands of records, specific workflows.Large teams, heavy traffic, strict compliance needs.

    If your needs fall in the right-hand column, I'll say so before you spend anything. Sheets has real limits, and I'd rather point you to the right tool than build something you'll outgrow.

    How a project works

    1. 01

      Tell me the problem

      A short note on what you track, who uses it and what takes too long. Share a copy of the sheet if you have one.

    2. 02

      Get a plan and a price

      I reply with questions, then a written plan of what I'll build and a fixed quote.

    3. 03

      I build on a copy

      Work happens on a copy of your file with test data, so your live sheet keeps running.

    4. 04

      Switch over and keep it

      We test it together, move it live and you get a short guide to what runs when.

    Integrations

    Google Sheets can talk to most tools a small business uses. These are the ones I connect most often. If a service has an API, it can usually connect.

    StripeCard payments through Stripe Checkout or Payment Links, matched back to the right row in your sheet. SMS textingText reminders, confirmations and alerts sent from your sheet, with replies logged back to the right row. SquareSquare payments, orders and catalog items pulled into Sheets for reporting, reconciliation and payment links. PayPalPayPal checkout links and invoices created from your sheet, with every payment recorded on the right row. QuickBooks OnlineInvoices, payments and customers synced between QuickBooks Online and Google Sheets. Google FormsForm responses cleaned, routed and acted on the moment they arrive. GmailPersonalized emails sent from your sheet, and incoming emails and attachments read into it. Google CalendarCalendar events created, updated and read from your sheet for bookings, schedules and staff. ShopifyOrders, products and inventory pulled from Shopify into Sheets for reports, restocking and bulk updates. Something else?Any service with a REST API or a CSV export can feed your sheet.

    Who it's for

    Teams that already live in a spreadsheet and want it to do more of the work.

    Frequently asked questions

    What kinds of businesses do you work with?

    Small businesses, programs, clubs and nonprofits that already keep their work in Google Sheets, or want to. Most have between one and 30 people using the system.

    How much does a project cost?

    Every project gets a fixed quote before any work starts, based on what the system needs to do. Small automations cost far less than a full registration and payment system. There's no monthly fee from me unless you ask for ongoing help.

    Do I need Google Workspace, or does free Gmail work?

    Both work. Free Gmail accounts have lower daily limits, like 100 email recipients a day instead of 1,500. I'll tell you before we start if your account's limits will matter.

    Who owns what you build?

    You do. The sheet, the code and the data all live in your Google account. Nothing runs on a server of mine.

    What if I outgrow Google Sheets?

    I'll tell you before building if I think you will. Sheets is a good fit for thousands of rows and a small team. Past that, a real database and app make more sense, and your data moves over cleanly because it's already in tidy columns.

    How do we get started?

    Send a short note about what you're tracking and what's eating your time. If you can, share a copy of the sheet. I'll reply with questions, then a plan and a fixed quote.

    Can you work with a sheet that has customer data in it?

    Yes. I'm happy to work on a copy with sensitive columns removed or replaced with sample data. Card numbers should never be in a sheet at all, and in the systems I build they never are.

    Tell me what your sheet needs to do

    A few sentences is enough to start. I'll reply with questions, then a plan and a fixed quote.
