Switching to another invoicing management system in Italy is a decision that many small and medium-sized enterprises (SMEs) make when their current setup becomes more of a hindrance than an asset. One sign is that the invoicing software frequently generates rejected invoices – those rejected by the Exchange System (SdI) because they contain errors and must therefore be corrected and resubmitted; or that questions arise regarding the compliant storage of electronic invoices; or that invoice history is difficult to access. In other cases, you could prefer to consolidate your invoicing and collections into a single process. In all these situations, moving to a new e-invoicing platform is often the most sensible choice.

This article will explain how to recognise the right time to switch billing software, what to check before migrating, how to choose an electronic invoicing management tool suited to the Italian market, how to transfer data without loss, and what expenses and timelines to consider.

Key takeaways

• The need for efficiency often drives the decision to switch billing software, but in Italy, it must be planned around compliance with the SdI, document history, and active integrations.
  
• Electronic invoicing software for SMEs in Italy have to correctly handle the SdI, certified email (PEC) addresses, legally compliant record retention, and updates to the recipient code without causing operational friction.
  
• Migrating the billing software goes beyond simply exporting records: it requires validating historical data, planning a transition phase, and properly coordinating the change with customers, suppliers, and internal teams.
  
• The cost of a migration depends on the volume of documents, the complexity of the integrations, and the need for support, while the time required ranges from a few days to several weeks.
  
• Consolidating invoicing and payments onto one platform reduces manual steps and simplifies the day-to-day operations of your electronic invoicing management system.
  

Signs that it is time to switch billing software

Usually, a decision to change platforms doesn't stem from a single problem, but from a series of minor issues that arise daily. The real cost is often not the licence, but the time your team wastes on repetitive tasks and avoidable corrections.

Before deciding whether to switch billing software, look for signs the current system is no longer efficient. Here are the most common signs among Italian SMEs:

• The team spends hours correcting errors, re-entering data, or figuring out why an invoice was rejected or not delivered.
  
• Submissions to SdI result in rejections, unclear outcomes, or questions about retention.
  
• The management system does not integrate with accounting, orders, or payments.
  
• Maintenance costs rise without adding new features.
  

Beyond these practical considerations, there are strategic reasons. Many companies change their billing management system when they want better integration across orders, collections, and recurring payments. In that case, the old setup might still work, but it no longer aligns with the company's growth model. This is especially true for small enterprises looking for billing software that does more than generate documents – it truly supports the entire order-to-cash cycle.

What to review before migration: SdI compatibility, invoice history, and existing integrations

Before switching platforms, consider whether important records or files could be lost. Perform an initial check to avoid discovering too late, for example, that the history cannot be exported, that the customer and supplier master data contain errors or duplicates, or that integrations with enterprise resource planning (ERP) and accounting software will have to be redone from scratch.

Compatibility with the SdI

The first check concerns the SdI. The selected e-invoicing solution has to handle issuance, receipt, rejection notifications, and document retention. For most SMEs, the challenge isn't creating the invoice, but maintaining a steady month-to-month flow without manual intervention each time.

Invoice history

If years of records remain in the previous electronic invoicing management system, determine how much of that history you can carry over. This is not always the case: some platforms export everything in standard formats, while others produce fragmented or incomplete files. Check whether invoices are downloadable and remain linked to the correct credit memos, attachments, and references, so you can quickly retrieve them when needed.

Existing integrations

Integrations are often the most challenging part of switching billing software. An integration is an automatic connection between the business management platform and another company program that lets the two systems exchange information automatically; for instance, with the inventory system, the payment system, or the platform that manages subscription plans. When you switch software, these links have to be re-established on the new platform. Making a list of all connected devices in advance helps avoid unpleasant surprises on the day of the changeover.

Choosing billing software for Italy: SdI, PEC, and record retention compliance

When choosing a new electronic invoicing management system, look beyond just the interface or the price. In Italy, regulatory compliance comes first. An SdI-compatible solution has to support the correct format, transmissions to the SdI, and the corresponding outcomes.

Two often-overlooked aspects matter as well: PEC and legally compliant data retention. Changing billing platforms requires contacts and receipt channels to remain consistent, especially if some customers and suppliers still use PEC as their standard means of communication. Good e-invoicing tools for SMEs must also provide a reliable archive, making it straightforward to retrieve documents years later.

Requirements to be verified with the supplier

Before signing any contract, ask explicitly whether the platform supports:

• The submission and receipt of documents via the SdI
  
• The update of the recipient code and PEC references
  
• The compliant digital archiving or integration with qualified providers
  
• The complete export of history
  
• Application programming interfaces (APIs) or integrations with accounting, ERP, and payment systems
  

Confirm the new supplier offers excellent customer service that is responsive and available through various channels (email, phone, chat).

Make sure the supplier covers all these features to avoid the risk of switching billing management systems a second time after just a few months. Also consider your business growth: if you want to grow, the software must handle larger volumes and more complex processes without increasing manual work.

How to migrate without losing data: Exporting history, validation, and transition period

An orderly platform migration means treating data as a company asset, not as a simple export. The process consists of three main phases, each with a different objective:

Exporting the history

The first phase involves extracting records from the old system: master data, issued and received invoices, credit notes, attachments, document statuses, and relevant references. If the legacy electronic invoicing tool does not export everything natively, plan partial recovery or parallel storage for files that cannot be transferred.

Data validation

Next comes validation. Moving files alone is not enough: verify that the information is readable, consistent, and associated with the correct customer. Many projects hit a snag at this stage, because duplicates, incorrect tax ID numbers, or incomplete master data come to light. A preventive check greatly reduces repetitive corrections after the go-live.

Transition period

The transition period is equally important. In many cases, it is advisable to keep the previous system available for reference for a limited time while rolling out the new SdI-based electronic invoicing software. This lets the team compare documents, handle exceptions, and get familiar with the updated workflow without interrupting business activities.

How to notify customers and suppliers of changes: Update of the recipient code and PEC address

When switching billing software, the technical aspects alone are not enough: customers and suppliers have to be informed clearly and promptly. If you adopt a new recipient code or update your PEC address, the biggest risk is documents reaching the wrong channel or getting stuck while awaiting correction. That is why you need to treat communication as part of the migration process, not a secondary step.

The best rule is simple: first notify the partners with whom you exchange the most files, then extend the notification to the rest of your customer and supplier base. State when the replacement e-invoicing platform will be active, what reference numbers will need to be used, and what operational changes will take place. If volumes are high, prepare a standard message for support staff and the administrative department so everyone responds consistently.

What needs to be updated in practice?

Always include the following elements when communicating with partners:

• The new recipient code, if provided
  
• Any updated PEC address
  
• The effective date of the switch
  
• Instructions for documents that have already been issued but not yet received
  

This step reduces errors, delays, and disputes. Above all, avoid making the customer feel the invoicing software change is their problem when it affects internal infrastructure.

How much does a migration cost, and how long does it take?

Migration expenses vary greatly depending on three main factors:

• Company size
  
• Quantity of documents to be transferred
  
• Complexity of integrations
  

For an SME with simple processes, the budget can remain modest; for a company with multiple locations, subscriptions, and custom integrations, costs rise quickly. SMEs have to evaluate e-invoicing tools based on more than the subscription fee, including the total migration expense.

Project duration depends mainly on the level of preparation. If the master data and history are already in order, switching to new billing software could take just a few days for set-up and testing. However, if you need to clean up the data, redo integrations, and coordinate multiple departments, the project could take several weeks. The deciding factor is rarely the technology itself, but the quality of the initial data.

Another overlooked expense is delay. Sticking with an inadequate system often means wasting time on manual processes, discrepancies, and slow reconciliations. For many companies, real savings come when the replacement set-up reduces routine tasks and better integrates invoicing, collections, and accounting.

How Stripe simplifies the transition

Stripe offers a variety of solutions that help businesses in Italy manage payments, invoicing, and recurring charges in a straightforward, automated way. Below, we examine them in detail.

How does Stripe Invoicing + A-Cube ensure full compatibility with the SdI?

If you want to switch billing software without creating another operational silo, choose a solution that combines documents and payment collection. With Stripe Invoicing and the integration with A-Cube for managing Italian electronic invoicing, you can use an SdI-based setup that consolidates billing and payments into a single system.

The benefit for an SME is clear: fewer tools to coordinate, fewer manual steps, and fewer discrepancies between billing and collections. Instead of maintaining separate e-invoicing and payment platforms, you can centralise the workflow and simplify reconciliation. This is particularly helpful for companies issuing recurring invoices, managing international customers, or seeking clearer control over their cash cycle.

Automating recurring revenue with Stripe Billing

If your company offers subscriptions, recurring fees, or pay-as-you-go plans, Stripe Billing manages the entire recurring revenue cycle in a simple and automated way. This is the natural complement to Stripe Invoicing: while the A-Cube integration handles invoice issuance and submission to the SdI, Billing manages renewal logic, plan updates, and automatic payments.

For an SME considering a switch in its invoicing management system, the most tangible benefits are:

• Automatic recurring invoicing, with renewals, upgrades, and downgrades handled without manual intervention
  
• Recovering failed payments through intelligent retries and automatic reminders to reduce involuntary abandonment
  
• Flexible pricing models – from flat-rate plans to pay-as-you-go or tiered plans – are useful if your pricing structure changes over time
  
• Reporting on recurring metrics, so the finance team has a clear picture of earnings, uncollected payments, and subscription trends
  

Fewer obstacles for the team

There is also an organisational benefit. When your electronic invoicing software for SMEs interfaces with payment systems, the finance team works from a single data source, and the sales team encounters fewer issues when managing customers. For those seeking a platform change while preserving speed, this integration is often the deciding factor.
