Pagero and Thomson Reuters ONESOURCE are now one vendor: Thomson Reuters acquired Pagero in 2024 and markets it as ONESOURCE Pagero. IDC placed both it and Sovos in the Leaders category of its September 2026 e-invoicing assessment. ONESOURCE Pagero leads on network scale, with roughly 14 million companies reachable. Sovos leads on measured production reach in France. Network model against compliance depth is the axis.

Yes, since 2024. Thomson Reuters acquired Pagero for $800 million and markets the offering as ONESOURCE Pagero within its corporates segment. Buyers evaluating “Pagero” and buyers evaluating “Thomson Reuters ONESOURCE e-invoicing” are evaluating the same platform, and this page covers both.
IDC records more than 20% annual growth since the acquisition, alongside 65,000 active e-invoicing customers and a network reaching roughly 14 million companies. It also records that the integration is still settling, which matters when comparing a recently combined vendor against a single-origin one.

This is the clearest difference. ONESOURCE Pagero operates an open interoperable business network reaching roughly 14 million companies and interoperating with more than 100 external networks, carrying the full purchase-to-pay and order-to-cash document set. Sovos operates the Sovos Compliance Network with direct tax authority integration across mandated jurisdictions.
The distinction matters most for supplier reach. A business whose problem is connecting thousands of trading partners across AP and AR is buying network scale. A business whose problem is staying compliant as mandates change across many countries is buying regulatory depth. Both vendors do both, and IDC placed both in the Leaders category, but their centers of gravity differ.
France is the one market where production reach is publicly measurable, because the mandate requires platforms to register the organizations they serve. As assessed on 21 September 2026, three weeks after the mandate went live, the Sovos-powered network carried 169,235 registered organizations and Pagero 2,169, with SAP at 1,881 and Avalara at 1,771.
Those figures count registered organizations in a single market rather than global customers, and ONESOURCE Pagero reports a far larger global network. They measure different things: one is total reachable trading partners, the other is organizations registered under a live clearance mandate in one country. Both are worth asking about, because a network reach figure does not tell a buyer how a platform performs when a mandate switches on.
IDC records the integration as still settling, and it records customer experience during it. Customers reported process and approval changes, delivery delays, escalations and the loss of experienced staff following the acquisition. Thomson Reuters reported that delivery leadership was retained and pointed to improving support metrics, and replaced country-specific delivery teams with a unified global organization and an account team model. IDC advises buyers to test current performance directly.
IDC records concerns about Sovos too: support consistency described by customers as country-driven and uneven across markets, and coverage comparatively less mature in parts of APAC. Sovos reported moving to a global platform approach intended to standardize support. The same advice applies in both directions, which is to speak to references in your own regions about a recent mandate go-live.

Sovos may be less suitable where supplier network reach is the deciding requirement, or where the business is already committed to ONESOURCE across direct and indirect tax.
Yes. Thomson Reuters acquired Pagero in 2024 for $800 million and markets it as ONESOURCE Pagero within its corporates segment. Searches for either name refer to the same platform.
ONESOURCE Pagero publishes the larger figure, with compliant invoicing across about 90 jurisdictions and 155 mapped obligations, against 60+ countries and territories for Sovos with 33 operating clearance or CTC models. Coverage definitions differ between vendors, so compare the markets you operate in.
On registered organizations, Sovos. As assessed on 21 September 2026, the Sovos-powered network carried 169,235 registered organizations and Pagero 2,169. That measures registration under one mandate in one country, not global scale, where ONESOURCE Pagero reports a network reaching roughly 14 million companies.
IDC recorded customers reporting process changes, delivery delays and loss of experienced staff following the acquisition, and records Thomson Reuters citing retained delivery leadership and improving support metrics. IDC advises testing current performance directly rather than relying on either account.
Some businesses run one vendor for network-based document exchange and another for tax compliance, particularly during a migration or where a mandate lands in a country one vendor covers natively. The trade-off is a second integration and clear ownership of each obligation.
