Procountor + CRM: How to unify finance and sales in one system

TLDR
– Disconnected sales and finance systems are one of the most common operational bottlenecks in Finnish SMEs
– Procountor-CRM integration eliminates duplicate customer records and copy-paste errors
– Invoices can be created directly from a won deal — no manual data entry
– Resappi’s Procountor integration includes two-way customer sync, invoice automation and payment status visibility in the CRM
– Setup takes a day, not a month-long project

The problem: the copy-paste curse of two disconnected systems

Does this sound familiar? A salesperson wins a deal, logs it in the CRM, emails the accountant — or creates an invoice manually in a second system — and hopes all the details are correct. The accountant creates a customer record in Procountor. About one in five times, something goes wrong: the name doesn’t match, the address is old, the reference number is missing.

This isn’t an edge case. This is the norm in Finnish companies with 5–50 employees.

Duplicate maintenance isn’t just slow — it’s expensive. If transferring data takes 20 minutes per deal and a company closes 30 deals a month, that’s 10 hours a month spent on copying. Ten hours that could be spent on actual customer work.

What unifying finance and sales actually delivers

When Procountor and the CRM talk to each other, the practical benefits fall into three categories:

Speed

An invoice is generated minutes after a deal is won, not days later. The customer doesn’t wait. Cash flow improves.

Accuracy

Customer name, business ID, address and payment terms come from the registry — not from the salesperson’s memory. The number of invoice errors drops dramatically.

Visibility

Salespeople can see directly in the CRM whether a customer has paid their last invoice. Previously, this required calling the accountant or sending an email. Both sides work smarter, not more.

Procountor API basics — what the integration actually does

Procountor provides a REST-based API that allows external systems to read and write data. Building the integration yourself is possible but requires technical knowledge of OAuth 2.0 authentication and Procountor’s data model.

For an SME, three core API capabilities matter:

Customer registry: Fetch, create and update customer data. When a new customer is won in the CRM, the integration first checks whether the customer already exists in Procountor by business ID — and only creates a new record if one is missing.

Sales invoice: Create an invoice draft with deal data. The Procountor API accepts invoice line items, payment terms, reference numbers and a PDF generation command.

Payment status: Retrieve invoice payment status. This data can be returned to the CRM so salespeople see overdue accounts before their next contact.

Resappi’s integration is built on top of these three core capabilities. See the technical integration documentation.

Practical use cases

Case 1: Invoicing directly from a won deal

A salesperson marks a deal as “Won” in Resappi’s CRM. The system asks: “Create invoice?” — or creates it automatically if the company has configured it that way. The invoice opens in Procountor pre-filled with:

• Customer name and business ID fetched from the Finnish Business Information System
• Products and prices from the deal, directly as invoice lines
• Agreed payment terms (14 days, 30 days, etc.)
• Project reference, if project billing applies

The salesperson or accountant reviews and sends. No copying required.

Case 2: Two-way customer data sync

When an accountant updates a customer’s billing address in Procountor, the change syncs automatically to the CRM. And vice versa: if a salesperson corrects a phone number in the CRM, the change goes to Procountor.

One source of truth, two views.

Case 3: Payment status visibility for the sales team

A salesperson opens a customer profile in the CRM before making a call. They see directly: last invoice sent April 3rd, due date April 17th, unpaid. They can decide — raise it at the start of the call, or route it to billing first.

This information previously required a separate request to the accountant.

Resappi’s Procountor integration in practice

Resappi has built its Procountor integration natively — it’s not a separate add-on or third-party middleware, but part of the core product.

What the integration includes:

• Customer sync (bidirectional, real-time or scheduled)
• Invoice creation from a deal (manual or automatic trigger)
• Payment status fetch to the CRM dashboard
• Product catalog sync from Procountor products to CRM quote templates
• Error handling and alerts: if the sync fails (e.g. business ID not found), the system notifies the user — it doesn’t silently discard data

Setup: API key from Procountor, configuration in Resappi, test with one deal. Typical time from zero to working: 4–8 hours.

See the full description on the integrations page or industry-specific implementations.

Summary: stop copying, start selling

Procountor is an excellent financial management system. A CRM is an excellent sales system. But if they don’t talk to each other, someone ends up acting as the human integration between them — and that’s expensive, slow and error-prone.

Integration isn’t a luxury. It’s basic hygiene for any company that wants to grow without administrative burden growing at the same rate.

Book a demo and let’s look at what the integration would look like in your process. You need your Procountor credentials and 15 minutes — we’ll handle the rest.
