PV Constructions case study

PV Constructions runs several companies. Before this project each had its own system, which meant the same work done several ways and no view across the group without someone building one.

The work was to bring them onto one platform with their books kept properly separate, so a person can move between companies with one login while the accounts stay as distinct as the law requires.

Definition

What we implemented for PV Constructions

PV Constructions runs several companies on one Odoo system with secure company-wise data separation. A single login switches between companies; sales runs a standardised quotation-to-order workflow across all of them; branded PDF documents and email go out automatically; and accounting covers chart of accounts, taxes, journals, bank management, payment processing and financial reporting per company with a view across the group.

Multi-company is one of the configurations that is cheap to set up correctly at the start and expensive to retrofit. Which records are shared and which are strictly separate has to be decided before the first transaction is posted.

Multi-company: Separate legal books in one database, with controlled sharing between them.
Company switching: One user moving between companies without logging out, seeing only what they should.
Data separation: Which records are strictly per company. The decision that defines a multi-company build.
Standardised workflow: The same process in every company, so a report means the same thing across the group.

The challenge

What was not working at PV Constructions

Managing several companies through separate systems created administrative overhead, inconsistent processes and limited visibility across the business. The group needed one platform that could manage multiple companies securely, automate sales workflows, generate professional business documents and maintain accurate financial records with statutory compliance.

Each company had its own system
Separate systems mean separate logins, separate processes and separate versions of the same master data.
Processes differed between companies
Without a standard workflow, a figure from one company did not mean the same thing as the same figure from another.
Documents were produced manually
Branded quotations and business documents prepared by hand are slow and inconsistent between companies.
Group visibility required assembly
Any view across the companies had to be built from exports rather than read from a system.
Compliance work was repeated
Statutory requirements handled separately in each system multiplied the same effort across the group.

What we built

What the implementation covered

The implementation covered multi-company structure, sales and accounting together, because the three decide each other.

Multi-company structure

Several companies in one database with secure company-wise data separation, so each set of books stays as distinct as it needs to be.

Separate booksSecurePer company

Single login

One login with seamless switching between companies, so a user working across the group does not maintain several sets of credentials.

One loginSwitchingAccess rules

Sales workflow

A standardised quotation-to-sales process applied across all companies, so the same stage means the same thing wherever it is reported.

QuotationStandardisedAcross group

Documents and email

Automated email communication and branded PDF generation, so what reaches a customer is consistent regardless of which company sent it.

Accounting

Chart of accounts, taxes, journals and bank management configured per company, with payment processing and financial reporting on the same structure.

Financial reporting

How it works now

How PV Constructions runs on Odoo today

The group now runs on one platform with properly separated books, one standard process and reporting that works both per company and across the group.

Companies separate where it matters — secure company-wise data separation keeps each set of books distinct.
One login across the group — users switch companies without a second set of credentials, within their access rights.
The same sales process everywhere — so a pipeline figure from one company is comparable with another.
Documents branded and automatic — quotations and business documents generated rather than prepared.
Accounting configured per company — chart of accounts, taxes, journals and bank, with reporting across all of them.

PV Constructions — the Odoo screens built for this implementation — **In the system** — the configuration built for this project.

Results

What changed

What the client reports back, in their terms. We publish no percentages here because the project did not measure any, and a number we cannot stand behind is worth less than one we can.

Centralised management

Several companies managed from one platform rather than from several systems with their own habits.

Accounting accuracy

A properly configured chart of accounts, taxes and journals per company improved both accuracy and compliance.

Financial visibility

Real-time reports replaced month-end assembly, so the group position is read rather than built.

Professional documents

Branded PDFs and automated email made customer-facing communication consistent across the companies.

Standardised workflows

The same process in every company means figures are comparable and training transfers between them.

Room to grow

Adding another company to the structure is configuration rather than another system.

FAQ

PV Constructions: frequently asked questions

What did OdooBots implement for PV Constructions?

A customised Odoo ERP for multi-company management, sales and accounting: secure company-wise data separation, single login with company switching, a standardised sales workflow, automated email and branded PDF generation, and accounting with chart of accounts, taxes, journals, bank management and financial reporting.

Can Odoo run several companies in one database?

Yes, with separate books per company and controlled sharing between them. What has to be decided first is which records are strictly per company and which are shared, because that structure is cheap to set up correctly and expensive to retrofit.

How does company switching work?

A user signs in once and moves between the companies their access rights allow, seeing only that company’s records while they are in it. It removes the several-logins problem without weakening the separation between the books.

Does each company keep its own accounts?

Yes — chart of accounts, taxes, journals and bank accounts are configured per company, with reporting available both per company and across the group. That is what keeps statutory compliance straightforward while still giving management one view.

Would this suit a group like ours?

If you run several companies with similar processes, almost certainly. The design question is where separation is legally required and where sharing is useful, which is the first thing the free diagnosis call covers.

Running something similar to PV Constructions?

Tell us how many companies you run and whether they share customers or stock. Those two answers decide the structure, and the diagnosis call is free.
