ERP system for installation and contracting businesses From quote to completion certificate – tied to the tax authority, in a single system.

Q: Do we need NAV Online Invoice access?

For automatic invoice retrieval, yes: enter the technical user created on the NAV Online Invoice portal (name, password, signing and exchange key) once in Settings, and from then on the system fetches new incoming and outgoing invoices every night. Everything else works without it — but partner lookup by tax number uses the same connection.

Q: Where is our data, who can access it?

Every client gets its own, isolated instance with its own database — no database shared with other companies. Inside your company you assign access: admin and user roles, permissions in four areas (e.g. someone sees stock but not controlling). Every meaningful action is logged.

Q: How do the item and partner masters get in at the start?

The item master imports from CSV or Excel (SKU and name required, other columns optional; an existing SKU is updated, not duplicated). Partners are looked up from NAV by tax number, or entered manually — private individuals and foreign companies too.

Q: What if I don't want a supplier invoice in stock?

At the incoming invoice you choose: Material purchase (Goods receipt) — lines matched to items increase stock; or Material purchase (no stock) — recorded as a cost immediately, e.g. when the material was installed on site right away. The program never books anything by itself; you confirm every invoice.

Get rid of scattered spreadsheets, notebooks and lost paperwork. P1network's contractor software connects quotes, stock, staff scheduling and finance on one screen. Automated workflows, so your time goes into the work — not the admin.

Module tour

Every tool for successful jobs – business management features

What you see here is not a promise for the future but the system that works today. Every module is strictly permission-controlled, so colleagues only see what they really need for their daily work. Tabs marked “soon” are the next releases.

01 · Cases and projects

Trackable jobs from the first survey to successful invoicing

One job, one partner. Follow the process from the submitted quote to closing on a single, clear screen — no chaos.

Clear projects: clean stages (Survey → Quote → Execution → Handover → Invoiced). You see exactly the owners, deadlines and the pre-set budget.
Material and labour items on the case: with totals; items can be taken over from the quote in one click. Log and events, team, attached documents.
Fast quoting: build quotes in moments from the built-in item master. Live preview while typing and numbering tailored to your company.
Completion certificate in a few clicks: an official record from the partner master data, amount in words automatically, ready to print.
Digital worksheet: forget paper! A worksheet signed on site on a tablet instantly becomes a locked, sealed, timestamped PDF.
Team rota and scheduling: plan weekly jobs, leave and sick days in a shared, easily edited calendar.

OverviewQuotesCasesWorksheetsSchedulingCompletion certificatesService

Cases overview: open, in execution, awaiting quote, overdue — filters by status and stage; owner, deadline and value per row.

02 · Stock and warehouse

Stock filled automatically from NAV invoices

Stock here is not a manually kept number but live data refreshed continuously from real movements and invoices.

Goods receipt without typing: turn the lines of incoming NAV invoices into stock in a few clicks. No more tedious manual entry.
Smart item master: everything in one place — purchase and list prices, suppliers, barcodes, serial-number tracking and product images. Easy CSV/Excel import and export.
Multiple stores: move goods between the central store and the vans in minutes. Documented movements, negative stock blocked by default.
Stock view and movement log: stock value, items below minimum and running low at a glance; every movement searchable, exportable to CSV, printable.
Installed equipment register: know exactly which system (alarm, camera, access control, router) you installed at which client, when, and how long the warranty runs.
Maximum security: equipment login data is available only to authorised users, with two-factor authentication, and every view is logged.

StockItem masterGoods receiptIssueTransferMovementsEquipmentPurchase orders

Stock: stock value, items in stock, below minimum, 30-day movement; stock bar and unit price per row.

03 · Partners (CRM)

Perfect records of clients and sites

Know exactly who the team goes to, where and why. Build your client database in moments.

Data entry without errors: just type the tax number and the system fills in the partner's official data from the NAV database (name, registered office, validity).
Manual partners too: for private individuals or foreign companies; the town fills in from the postcode; supplier / customer flags.
Detailed site management: per address you can record contacts, parking information, access details and safety rules, so the engineer does not meet the problems on site.
On-site survey form on the phone: power, IT, security or gate automation? Fill in the trade-specific checklists and attach tagged photos on site – even without signal.
Professional client reports: generate a signable PDF proposal for the client straight from the survey, with your own logo.
Map view and Document library: see sites and to-dos on a map, and store contracts securely, encrypted, permission-controlled.

CustomersSuppliersSubcontractorsContactsSitesContractsCustomer map

Partner master: tax number, address, type (supplier / customer), NAV validity and last lookup time.

04 · Finance

Finance automated: receivables and costs up to date

With the NAV technical user the system downloads incoming and outgoing invoices by itself every night. See your company's finances clearly!

Incoming invoices at a click: the system suggests the cost category from previous invoices (accept with one click, even in bulk), or receives the lines straight into stock.
Outgoing invoices and receivables: see exactly what was paid, what is overdue and how much retention is held. No more forgotten, uncollected invoices.
Hidden costs tracked: record payroll, contributions and bank fees too, for a true picture of your spending (automatic gross–net calculation, charged to the right month).
Commission made simple: calculate commission for staff from net, gross or turnover × %, and export the monthly lists to Excel.
Encrypted connection: NAV credentials are stored encrypted and never shown again in the interface.

OverviewOutgoingIncomingProforma invoicesCostsCommissionNAV Online InvoiceReceivables

P1network ERP system – Incoming invoices from NAV

Incoming invoices from NAV: issuer, performance date, gross / net, payment method; per row: assign with suggestion, receive into stock, ignore, lines.

05 · Controlling

Real-time financial decision support for owners

Base decisions on real data, not guesses! Controlling shows the company's exact results automatically from authentic NAV invoices and stock movements.

Management dashboard: instant overview of what matters — open cases today, current site visits, stock running out, overdue receivables and the current cash-flow result, versus the previous period.
Accurate P&L: see real revenue and spend net and gross. Weekly, monthly, quarterly, yearly breakdown, VAT balance and visual charts.
Revenue and result: accounting (performance-based) and cash-flow results side by side, with receivables, monthly breakdown, revenue per customer — Print / PDF in one click.
Material margin: sales value of issued goods minus their weighted purchase cost — for the period, also listing what it could not include.
Stock value to the second: always know how much money sits in the warehouse (at purchase and list price) — guaranteed to match the Stock module, because it computes from the same source.

Overview in yearly view: today's focus, four KPIs against the previous period, monthly cash movement, spend by category.

P1network ERP system – signed, locked worksheet

Bottom of a signed sheet: engineers' signatures in their rows, the client's at the bottom, and the audit line — signer, time, IP, SHA-256 of the sealed PDF.

New · Worksheets

Digital worksheet — signed on site, sealed and timestamped

The site-visit record that invoices are based on: the engineer fills it in on site, the client signs on a tablet, and the system produces a locked, sealed PDF.

Paper replicaSame as the paper form: client from the partner master, fault description, hourly and call-out rate underlined by a click, work number (ML-YYYY-NNNN automatic), engineer rows with time, hours and km, lined description and material list — printed to A4 the same way.

SignatureSign with a finger or stylus on tablet and phone: the client via “Sign and close”, engineers in their own rows.

StampDigital seal on the PDF (PAdES): on closing, the paper-layout PDF is sealed with the company's certificate; a qualified certificate (Microsec, NetLock) can be plugged in.

TimestampTimestamp and audit: signing time, signer name, IP address and device on the sheet and in the log; the SHA-256 of the sealed PDF is shown on the sheet; a timestamp authority can be plugged in.

LockedA closed sheet cannot be edited: the signed PDF downloads in one click; only an admin can unlock it, and then the signature is removed and must be redone.

E-mailSend to the client by e-mail with the signed PDF attached — the recipient is suggested from the partner's contacts, and the sending is visible on the sheet and in the list.

Security

Client passwords are not kept in a spreadsheet

The Equipment module holds login data for clients' systems — gate codes, recorders, alarm panels, network admins. That is why signing in alone is not enough there.

2FATwo-factor authentication: viewing a password requires, on top of login, the 30-second code from an authenticator app (Google / Microsoft Authenticator, Authy). Set up once with a QR code.

EncryptionEncrypted storage with a separate key: IP address, username, password and note are encrypted with a key that is not in the database — the database file alone cannot reveal them. NAV keys and Document library files are stored the same way.

Audit logEvery view is logged: who viewed a password, when and from which IP — in the activity log, searchable even for deleted users.

PermissionsSeparate view permission: everyone sees the row, but the View button only works for users the admin has granted this right — independent of edit and delete rights.

LockoutLockout: after three failed logins the username + IP pair is locked for 15 minutes; passwords are at least 8 characters, with a generator and e-mail reset.

VaultVault from the site: the Survey site sheet only shows whether an access record exists and takes you to Equipment — secrets deliberately do not live in the survey.

P1network ERP system – viewing access credentials with a two-factor code

The View button asks for the six-digit code; only then does it show the IP, username and password — and writes to the log who viewed it.

Switching

What it replaces

These run side by side at most contractors today — P1network's modules were built for exactly these.

×An Excel quoting sheet only one person understands → itemised quotes with numbering and preview
×Retyping supplier invoices into stock → goods receipt from the NAV invoice lines
×A weekly rota in Excel, sent around → a shared weekly table in the system
×Gate codes and passwords in chats and notebooks → Equipment, encrypted, with 2FA, logged
×Photos and survey notes scattered on phones → survey form with photos, signature, PDF report
×“What's outstanding?” — calling the accountant → Controlling from NAV invoices, fresh every morning

FAQ

What people ask at demos

If yours isn't here, send it via the form — we reply within one business day.

Do we need NAV Online Invoice access?

For automatic invoice retrieval, yes: enter the technical user created on the NAV Online Invoice portal (name, password, signing and exchange key) once in Settings, and from then on the system fetches new incoming and outgoing invoices every night. Everything else works without it — but partner lookup by tax number uses the same connection.

Where is our data, who can access it?

Every client gets its own, isolated instance with its own database — no database shared with other companies. Inside your company you assign access: admin and user roles, permissions in four areas (e.g. someone sees stock but not controlling). Every meaningful action is logged.

Can it be used on the phone on site?

Yes. The interface adapts to phones, and the Survey page can be installed on the home screen and opens without signal for a site opened earlier. Entered data and photos wait on the phone and upload by themselves as soon as there is a connection.

How do the item and partner masters get in at the start?

The item master imports from CSV or Excel (SKU and name required, other columns optional; an existing SKU is updated, not duplicated). Partners are looked up from NAV by tax number, or entered manually — private individuals and foreign companies too.

What if I don't want a supplier invoice in stock?

At the incoming invoice you choose: Material purchase (Goods receipt) — lines matched to items increase stock; or Material purchase (no stock) — recorded as a cost immediately, e.g. when the material was installed on site right away. The program never books anything by itself; you confirm every invoice.

How safe are client passwords in the Equipment module?

They are stored encrypted with a separate key that is not in the database — the database file alone cannot reveal them. Viewing requires a two-factor code on top of login (Google / Microsoft Authenticator), and the log records who viewed a password, when and from which IP. Three failed logins lock the account for 15 minutes. See the Security section.

Can we take our data out?

Yes. The item master, stock movements and lists export to CSV; reports and documents print or save to PDF. The database is yours.

How do we start?

In a 30-minute online demo we walk through one of your own jobs: quote, material, rota, invoice. Then, in your own instance, Company settings (logo on documents), the NAV technical user and the item import are the first three steps. For a quote we ask for the number of engineers and the modules you want to use.
