ECI Software Solutions transitioned from letting acquisitions operate independently to a "fully absorbed" model. This change was driven by the operational difficulties and lack of scalability from having disparate ERP and HRIS systems, which hindered reporting and efficiency.

OpenAI's move into shopping features is hitting a major hurdle: sales tax complexity. This forces them to build a sophisticated backend for tax collection and remittance, similar to Amazon, rather than just being a thin AI layer. This will necessitate a hiring push for compliance and tax experts.

ECI's experience in the Netherlands shows diligence claims about language skills can be unreliable. After one Dutch acquisition with excellent English, a second required funding business English classes. This highlights the risk of extrapolating assumptions from one deal to the next.

A carve-out is not a simple asset transfer but the creation of a new, independent company. This process involves establishing entirely new IT, security, payroll, and benefits systems, which are often deeply entangled with the parent company's infrastructure and require significant time and resources to stand up.

When scaling a product internationally, identify universal components (like an invoice template) and build them as a common service. Then, use a well-designed API layer to connect to region-specific logic, such as different payment rails or tax rules, avoiding fragmented, country-specific products.

When SPS Commerce acquired a Dutch company, they discovered their lawyers in the Netherlands could not advise on French labor laws for the target's Paris office. This highlights that "Europe is not one country" in M&A; acquirers need a separate bench of local experts for each jurisdiction.

Unlike previous deals, a German acquisition required a complete, simultaneous language localization across all systems. This "language lift" included everything from the website and lead-gen to contracts, support portals, invoices, and automated billing reminders, all launching on the same day.

Don't assume selling in Europe is the same as North America; it constitutes a new market entry. Companies often make a 'ton of assumptions' about marketing data, buying cycles, language, and regulations, underestimating the difficulty and risk of the move.

Integrating a Swedish company reveals surprisingly complex expense reporting. Beyond reclaiming VAT, a key challenge is that any company reimbursement exceeding the government-stipulated per diem is treated as taxable income for the employee, creating a significant administrative and payroll burden.
