FieldN — field app and back office togetherA field service management app with a real back office behind it
A technician app alone does not run a service company. Someone still has to quote, dispatch, invoice, collect, count stock, pay salaries and file VAT. FieldN puts that back office in the same system as the field app.
Quick answer
FieldN is a field service management app with a back office built in. The technician app and the customer booking app are the front; behind them the office runs leads and quotations, dispatch, invoices and payments, double-entry accounting and the VAT report, parts stock and purchase orders, HR and payroll and reports and dashboards. Everything the field team does lands in the office side at once, and everything the office decides reaches the phone at once. See everything in FieldN.
What the back office covers

Three apps, one system: a booking portal and app for your customers, a technician app for Android and iPhone, and the office back end for dispatch, contracts, stock, invoices and HR. See all FieldN features.
One job, front to back
- Front: a customer books "AC service, 3 units" in your app, or a lead comes in on WhatsApp and the office sends a quotation.
- Office: the booking or accepted quote becomes a job; smart dispatch suggests the technician; the office sees it on the calendar and map.
- Field: the technician checks in with a photo, fills the checklist, records the parts used and takes the signature.
- Billing: the invoice is raised from the job, sent on WhatsApp with a payment link, and the payment settles it.
- Books and stock: the invoice, the payment and the parts used post to the ledger and come off stock on their own.
- Month end: the VAT report, the daily and collection reports and payroll come from the same data — nothing is typed twice.

Why the back office must be in the same app
When the field app and the office software are two products, every job is typed twice: once on the phone and once into the invoicing or accounting tool. Numbers drift, parts go missing from stock and the VAT return is built from a spreadsheet. In FieldN the job, the invoice, the payment, the stock movement and the ledger entry are one chain on one database, so the reports match the books and the books match the bank.

Field service app with back office — frequently asked questions
What is a field service management app with back office?
It is one system with two sides: a mobile app for technicians and customers, and an office web app for dispatch, quotations, invoicing, payments, accounting, stock, HR and reports. FieldN is built this way, on one database, so nothing is typed twice.
Do I still need separate accounting software?
No. FieldN has double-entry books with a chart of accounts, journal, trial balance, profit and loss, balance sheet, cash and bank accounts, expenses and a VAT report. Invoices, payments, purchases, stock and payroll post to the ledger on their own.
Can office staff and technicians have different access?
Yes. Roles and permissions decide which modules each user sees, with an audit log, login logs, two-factor sign-in and SSO in Settings.
Does the back office work on a phone?
The office side is a web app that works in any browser, including a phone browser. Technicians use the FieldN technician app on Android and iPhone.
Does the technician app work offline?
No. The technician app needs an internet connection; it is built for teams on mobile data.
