Company profile

Order-to-cash applications, agents and payment intelligence

Sidetrade develops an order-to-cash platform for the work between accepting an order and receiving, matching and forecasting payment. Credit teams, accounts-receivable managers and shared-service centres use its applications to issue invoices, prioritise collections, resolve disputes and apply cash. The same environment combines a proprietary payment-behaviour Data Lake with Aimie agents that can recommend or execute governed actions while returning exceptions and transcripts to finance teams.

Applications and workflow

From a clean invoice to matched cash

Eight O2C applications share data across credit, invoicing, collections, disputes, deductions, cash application, analytics and customer self-service. E-Order and E-Invoicing synchronises orders and invoices with ERP and CRM systems; Augmented Collection selects the next account, action and channel; Cash App interprets remittance information and routes unmatched items.

Data and agentic AI

Aimie learns from how businesses actually pay

Sidetrade's Intelligence Foundation normalises payment events from live order-to-cash workflows. The H1 2026 results release describes a proprietary Order-to-Cash Data Lake that has aggregated USD 10 trillion in B2B transactions across 45 million buyer companies since 2015. Sidetrade says its specialised language and predictive models use this behavioural evidence for risk, timing and next-action decisions. Aimie agents can call customers, qualify invoices and escalate exceptions within policies rather than behaving as a general-purpose chatbot.

Customer evidence

Cash results make an abstract workflow visible

FranceTV Publicité reports EUR 7.7 million of cash generated and a nine-day reduction in days sales outstanding after integrating collections, credit analysis and Aimie. Biffa describes the platform's move from transactional collections to a strategic finance role. Sodexo is deploying eight Aimie agents across billing, collections and payment tracking.

Footprint and positioning

Enterprise depth meets a new mid-market route

Sidetrade serves enterprises in 85 countries through teams in Europe, North America and Asia-Pacific. The United States supplied 30% of 2025 revenue and international markets 71%. Acquiring Sydney-based ezyCollect added an SMB-focused product and APAC base, while the O2C Intelligence 2030 programme is reorganising the enterprise platform around applications, agents and customer-built workflows.

Current 2026 update

What is changing at Sidetrade in 2026?

Sidetrade's first-half 2026 results (unaudited) give reported evidence for its AI-native shift: record half-year bookings, higher like-for-like profitability and stronger cash generation, while the new contracts are expected to contribute more to revenue only from Q4 2026.

Latest official evidence H1 2026 results Published 22 September 2026

The change in one sentence

Orders and margins moved first; revenue is expected to follow from Q4 2026.

New subscription bookings more than doubled and the like-for-like EBIT margin rose by nearly five points.

Four lenses on 2026

The same four-quadrant format used in the Company profile.

01 · Commercial traction

Record half-year bookings, more new customers and longer contracts

In the first half of 2026 Sidetrade signed EUR 5.16 million of new annual recurring subscriptions (ARR), up 112% and 20% more than in the whole of 2025. Total contract value reached EUR 18.71 million, up 194%. New customers accounted for 56% of bookings, against 30% a year earlier, and the average initial commitment lengthened from 44.5 to 48.8 months. North America provided 44% of bookings but just over 27% of subscription revenue. The AI-native products (Aimie Cash Collection Agent, Agent Builder Studio and Aimie IQ) generated EUR 1.02 million, or 33% of the EUR 3.11 million of new ARR signed in Q2, and 80 agents were on firm order: 26 Aimie Agents and 54 Customer Agents. After the half-year, on 29 July, Réside Etudes, a French operator of serviced residences, selected Aimie for cash collection. Sidetrade expects the contracts signed in the first half to contribute more significantly to revenue from Q4 2026.

  • Current signalNew ARR EUR 5.16m (+112%) · total contract value EUR 18.71m (+194%) · 33% of Q2 new ARR from AI-native products
  • Why it mattersBookings precede subscription revenue, so a larger, longer and more international order book is the earliest measured test of demand for the AI-native offer.

02 · Operating leverage

Margins rose while like-for-like operating costs fell

Revenue reached EUR 34.8 million, up 19% as reported and 21% at constant currency, including ezyCollect, consolidated since Q4 2025; subscriptions were EUR 31.3 million, or 90% of revenue. EBIT rose 22% to EUR 5.7 million, a 16.2% margin, including a EUR 1.9 million research tax credit. Excluding ezyCollect, the EBIT margin rose from 15.7% to 20.7%, and operating expenses fell by EUR 1 million, which Sidetrade attributes to cost discipline in R&D (helped by AI), sales and marketing. Gross margin was 74% as reported, against 77% a year earlier; excluding ezyCollect it rose 1.4 points to 78.4%, and subscription gross margin held at 89%. Net income rose 15% to EUR 4.7 million. Operating cash flow was EUR 9.1 million, against EUR 5.4 million a year earlier, both excluding the timing of the research tax credit.

  • Current signalLike-for-like EBIT margin 20.7% vs 15.7% · like-for-like operating costs down EUR 1m · operating cash flow EUR 9.1m
  • Why it mattersHigher revenue with lower like-for-like costs is reported operating leverage in a recurring-revenue model, not a projection.

03 · Sovereign stack

Own data, models and compute, now under one agent framework

According to Sidetrade's H1 2026 results release, its Order-to-Cash Data Lake has aggregated USD 10 trillion in B2B transactions across 45 million buyer companies since 2015. The Data Lake feeds models that combine open-weight language models fine-tuned by Sidetrade with its own predictive models for payment behaviour, buyer risk and the next collection action; they run on Sidetrade's own GPUs (mainly NVIDIA H100 and H200) in its private cloud. SAFE, launched on 10 September 2026, is the common execution layer for the AI-native products: it selects a model for each task, governs agent autonomy, logs actions and triggers a deterministic escalation when human intervention is required. SAFE is already in production under the Aimie Cash Collection Agent, deployed with customers including Securitas, Accor and Sodexo. The infrastructure is certified ISO 27001, SOC 1 Type II and SOC 2 Type II, and agents are validated against the OWASP Agentic Top 10 before production. AI-native subscriptions include task volumes and O2C IQ consumption units produced on Sidetrade's infrastructure, rather than being priced on third-party tokens. On 30 June 2026 The Hackett Group gave Sidetrade a 2026 Innovation Award in the Technology Operations category, following an evaluation of demonstrated results.

04 · What to watch

Three questions for the next disclosures

The next results will show whether the order book turns into revenue growth.

  • Revenue conversionDoes subscription revenue growth accelerate from Q4 2026 as the contracts signed in the first half start contributing?
  • ProductionDo Agent Builder Studio and Aimie IQ enter production with beta customers in Q4 2026, as scheduled?
  • ezyCollectDoes the gap between reported (74%) and like-for-like (78.4%) gross margin narrow as the acquisition is integrated? Separately, financial debt was EUR 28.0 million at end-June, mainly the EUR 25 million seven-year loan that financed the acquisition.
