Your spreadsheet already runs your business.
We turn it into the web app your team uses every day.
Web App Solutions LLC (formerly FlowCetra) builds custom business web applications for auto shops, dealerships, contractors and inspection companies. We build on top of the Google Sheet your office already works in — so your records stay where they are, and your staff gets real screens, forms, invoices and reports instead of endless rows.
One-time cost. No monthly software fees. Most projects are ready in days, not months.
There is no migration, no data cleanup project and no new system for your staff to learn from scratch. Your spreadsheet stays the place your data lives.
| 1. Your Google Sheet | 2. The application | 3. Your team |
|---|---|---|
| Keep the spreadsheet you use today. Your data stays in it and stays yours — open it, edit it or export it any time. | We build screens, forms, search, job cards, invoices, PDF files and reports directly on top of that sheet. | Office staff and field crews all work in one place, from a computer or a phone browser. No app store download. |
The four steps of a project
- We review your workflow. A short call and a look at your sheet, to find the manual work eating your week — the retyping, the rebuilding, the chasing.
- We build on your data. The application is shaped around your columns, your job types and your team's roles.
- Your team goes live. You get a link. It works on the phones your crew already carries, and it looks like the work they already do.
- We adjust it as you grow. New job type, new report, new hire, new location — the application changes with the business.
Nothing about your records has to change. Only what it takes to use them.

Below are two screen shots from the same auto shop project. Customer names and phone numbers have been blurred for privacy. Everything else is the live system.
Auto Shop Management
Built for mechanic shops. Vehicle history, repair jobs, parts and expenses, invoices, inspections and employee activity in one system instead of five tabs.
Vehicle Inspection Reports
A pre-purchase inspection platform for technicians in the field: guided mobile reporting, photo capture, and a client-ready PDF report the moment the inspection ends.
Contractor Invoicing & Projects
For remodeling and field-service crews. Track projects and labor as work happens, then turn logged hours and materials into an invoice without rebuilding it by hand.
Expense Tracking & Budgeting
A live financial portal for teams and departments: log spending as it happens, categorize it, and see where the month stands against the budget.
Dealership Management
Inventory, sales, customer records and daily workflow for used car dealers — every unit and every deal tracked in one place the whole floor can reach.
Facebook Marketplace Listing
A done-for-you service: your entire vehicle inventory is posted to Facebook Marketplace automatically, twice a month. Buyers message you directly.

If the work lives in a spreadsheet today, it can live in an application tomorrow. These are the operations we know best:
| » Auto dealerships | » Repair shops | » Contractors | » Towing companies |
| » Inspection companies | » Logistics & dispatch | » Roofing companies | » Cleaning companies |
| » Property management | » Warehouses | » Moving companies | » Insurance adjusters |

- What does Web App Solutions LLC do?
- We build custom business web applications on top of a Google Sheet you already own. You get real screens and automation, and your data stays in a sheet you control.
- Is this the same company as FlowCetra?
- Yes. Web App Solutions LLC was formerly FlowCetra — same team, same projects, same applications. Only the company name changed, and every application already delivered keeps running exactly as it is.
- Is there a monthly subscription?
- No. You pay once for the project. There is no subscription, no per-user fee and no renewal. The application runs on the Google account you already have.
- How long does a project take?
- Most applications go live in days, not months. We review your workflow, build on your existing data, and hand your team a working portal — with no migration project first.
- Who owns the data?
- You do. It stays in a Google Sheet under your own account, with the application and automation on top of it. You can open it, export it or take it elsewhere at any time.
- What kinds of businesses is this for?
- Job-based operations across 12 or more industries — auto dealerships, repair shops, contractors, towing, inspections, logistics dispatch, roofing, cleaning, property management, warehouses, moving companies and insurance adjusters. More generally, any kind of business that keeps its records by entering data into spreadsheets. If your office types the same information into a sheet every day, we can build an application on top of it.
- Will it work on my crew's phones?
- Yes. Every project works in any phone browser — no app store download and no company devices required.
