Accounting certainty, delivered from Dhaka.
CERTA& Advisory is an accounting outsourcing firm: bookkeeping, management accounts, payroll and VAT/tax compliance for companies and accounting practices across the UK, USA, Canada and Europe, run by qualified accountants in your own software.
One accounting partner, the full ledger to filing.
Every engagement starts with the function costing your team the most time. Most clients consolidate more of their accounting workload with us once the first handover proves out.
Full-Service Accounting Outsourcing
A single dedicated team across bookkeeping, payroll and tax — scoped and priced as one engagement, one point of contact, one monthly close.
The default starting point for finance teams and accounting practices replacing more than one function at once.
Accounting & Bookkeeping
Day-to-day ledgers, bank reconciliations, management accounts and reporting, run to your existing chart of accounts and close calendar — directly in Xero, QuickBooks, Sage or FreeAgent.
Payroll
Accurate, on-time payroll runs across multiple jurisdictions, with statutory filings and payslips handled to each market's calendar.
VAT & Tax Compliance
VAT/GST returns, statutory filings and catch-up compliance work, tracked against each jurisdiction's deadlines.
Year-End Accounts & Reporting
Statutory year-end accounts and management reporting prepared to GAAP/IFRS conventions, ready for your review and sign-off.
Management Reporting & Advisory
Cost benchmarking, process design and transition planning for finance teams and practices weighing what to outsource next.
Four steps from first call to live delivery.
Most clients are through scoping within a week and see their first full reporting cycle inside 60 days.
Discovery call
We map your current process, tools and pain points against what we can take off your plate first.
Scoping & proposal
A fixed scope, team structure and pricing — no vague retainers, no surprise line items later.
Onboarding & transition
A structured handover with parallel runs before we take anything fully live, so nothing drops.
Ongoing delivery
A dedicated team, a named lead, and regular reporting — reviewed and adjusted as your business changes.
Why finance teams choose CERTA&
Six reasons finance directors and practice owners move their back office to us — and keep it here.
Qualified and part-qualified accountants
An English-fluent pipeline of ACCA and ICAB-track accountants — we hire and train from the top of it.
Your software, not ours
We work directly in Xero, QuickBooks, Sage or FreeAgent — no migration, no new tool for your team to learn.
Meaningful cost efficiency
Lower delivery cost than an equivalent in-house or onshore-outsourced team, without cutting corners on oversight.
Fixed scope
ACCA / ICAB
Built around your working day
Working hours structured to overlap with UK, US, Canadian and European business hours, not the other way around.
Fixed scope, fixed price
Every engagement is scoped before it starts — no vague retainers, no surprise line items later.
Confidentiality by default
Client data handled under signed confidentiality agreements and role-based access, from day one.
The team behind your ledger.
Every engagement is staffed by role, not by whoever's free — so you always know who's doing the work and who's reviewing it.
Engagement Lead
Your single point of contact: owns scope, timelines and the monthly review call.
Assigned before onboarding starts and named in your proposal — not a rotating helpdesk.
Senior Accountants
Handle bookkeeping, reconciliations and management accounts to your existing chart of accounts.
Payroll Specialists
Run payroll cycles and statutory filings against each jurisdiction's calendar.
Compliance Reviewers
Independently review VAT/tax filings and year-end accounts before anything reaches you for sign-off.
Who we work with.
We don't publish client names without permission — here's the shape of the companies we already support.
Growing SaaS & professional services firms
Replacing an outgrown in-house bookkeeping function ahead of their next funding or audit cycle.
E-commerce & multi-entity operators
Consolidating accounts across several trading entities into one consistent monthly close.
Accounting practices needing overflow capacity
Using us as their delivery bench during busy season without hiring onshore.
SMEs consolidating group reporting
Standardising bookkeeping across subsidiaries into a single reporting calendar.
Careers at CERTA&
