Your invisible back-office
Sars&Bay Partners is a team of Kazakhstani accountants supporting CPA clients via QuickBooks and now Swiss Treuhand firms as a dedicated back-office. We take over the most repetitive and time-consuming work – data entry, reconciliations and routine checks – so your advisors can focus on clients, not on bookkeeping.
Built for growing firms
We support:
- small and mid-sized accounting firms
- boutique accounting and tax practices
- family offices that need additional operational capacity
Back-office as a Service: we handle the routine, you keep the mandate
We take over the operational bookkeeping tasks that consume your team’s time but do not require partner-level expertise.
Solution For All Businesses
Why Treuhand firms choose Sars&Bay Partners
Proven international competence and experience
Our accountants combine international professional certifications (including ACCA and CFA) with foreign university degrees and several years of hands-on experience supporting US-based companies in QuickBooks Online. This ensures both technical accuracy and disciplined operational execution.
Clear legal framework and shared responsibility
Sars&Bay Partners operates as a registered legal entity within the Astana International Financial Centre (AIFC) and Astana Hub. Our services are covered by professional liability insurance, ensuring that responsibility for our work is formally defined and contractually shared.
Structured processes and quality control
We work with documented procedures, internal checklists and activity logs, applying the four-eyes principle to critical tasks. This provides transparency, traceability and consistent quality across all delegated back-office functions.
Final advisory decisions and client responsibility remain with the Treuhand firm
Simple, structured collaboration process
Initial assessment (30–60 minutes)
We meet online to understand your current workload, systems and pain points: what is overloading your team and what can safely be delegated.
Pilot on 1–2 mandates
We start with a limited number of clients. During the pilot we define responsibilities, refine processes and agree on reporting formats and communication channels.
SLA and scaling
Based on the pilot, we formalise a Service Level Agreement: scope, deadlines, quality metrics and escalation paths. Then we gradually increase the number of mandates handled by our back-office.
Monthly review
Once a month we run a short review call: what works well, what can be further automated, where we can reduce manual work and save time on both sides.
Security, confidentiality and responsibility
Professional liability insurance
Our work is covered by professional liability insurance, with clear limits and conditions set out in the contract. Within the agreed scope, we take financial responsibility for our deliverables.
Confidential handling of client data
We work exclusively within your chosen systems (QuickBooks, Bexio, etc.) using secure, role-based access. No client data are stored on local machines, and access is granted on a “need-to-know” basis.
Clear contracts and jurisdiction
We contract as a legal entity registered in the AIFC (Astana). This provides a transparent international legal environment, with familiar standards for foreign partners.
Swiss-Grade Precision meets US Operational Speed
For several years, Sars&Bay Partners has been supporting US-based companies through QuickBooks Online, providing ongoing bookkeeping, reconciliations and period-end preparation.
4 large operational clients in logistics, including companies acting as contractors within the supply chains of global groups such as Amazon and Costco
17 small and mid-sized businesses, requiring continuous operational accounting support
Dedicated B2B back-office partner for Swiss Treuhand firms. We focus on data, you focus on clients.
Frequently asked questions
Our team is based in Kazakhstan (Astana), and Sars&Bay Partners is registered in the Astana International Financial Centre. We work fully remotely and align our working hours with European time zones where necessary.
We only work inside your accounting systems, with secure access and, if required, two-factor authentication. Data export is minimised and controlled by your internal policies. We are happy to sign NDAs that reflect your standard compliance requirements.
Within our agreed scope of work, Sars&Bay Partners is responsible for the accuracy of the tasks we perform. This responsibility is backed by professional liability insurance and formalised in our service contract.
In practice, it often becomes an advantage: we can process documents and reconciliations while your team is offline, so by the time you start your day, the books are already updated. For live communication we agree fixed time windows that work for you.
By default, no. We operate as your internal back-office and communicate only with your team. If you need us to support clients directly, we can do this under your brand (white-label) under a separate agreement.
We operate strictly as a B2B White-Label Back-office. Since we are not Swiss-licensed tax advisors, we cannot legally sign off on financial statements or represent clients before the Swiss Tax Administration (ESTV). Our business model is designed to support you, not replace you: we handle the time-consuming data entry and reconciliation in bexio, providing you with clean, audit-ready data so you can focus on high-value advisory and client relationships.
