Accounting certainty, built around your working day.
CERTA& Advisory is an accounting services 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 Partner
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 hand off 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 defined 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.
Building an in-house function, or scoping it out. What actually changes?
The honest tradeoffs finance teams weigh before this decision.
| Comparison area | Building in-house | CERTA& Advisory |
|---|---|---|
| Getting started | Recruiting, interviewing, and onboarding a new hire. Typically weeks to months before they're productive. | Scoping starts within a week; most clients see their first full reporting cycle inside 60 days. |
| Coverage | One person's leave, turnover, or notice period is a single point of failure for your books. | A named team with defined roles: Engagement Lead, Senior Accountants, Payroll Specialists, Compliance Reviewers. Coverage doesn't depend on one person. |
| Cost structure | Salary, benefits, software licenses, training, and management time, whether or not workload is steady. | One scoped, fixed-price engagement. Priced before it starts, adjusted only when scope changes. |
| Scaling up | Re-hire and re-train each time the function needs to grow. | Scope adjusts within the existing engagement and team structure. |
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-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 team or an onshore provider, without cutting corners on oversight.
Built around your working day
Working hours structured to overlap with UK, US, Canadian and European business hours, not the other way around.
Defined scope, predictable fees
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.
Your data, handled like it's ours to lose.
Three structural facts about how an engagement actually runs, not a badge wall.
Signed before anything moves.
Every engagement runs under a signed confidentiality agreement before any ledger access, document, or credential changes hands.
Role-based access, not open access.
Only the named team members on your engagement can see your books: your Engagement Lead, Senior Accountants, Payroll Specialists, and Compliance Reviewers. Access is scoped to the role, not the office.
Your software, not a copy of it.
We work directly inside your existing Xero, QuickBooks, Sage, or FreeAgent. Nothing is migrated to a separate system, which means nothing exists in a second place to secure.
The team behind your ledger.
Every engagement is staffed by role, not by whoever's free. 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.
Jr Accountants
Part-qualified accountants building ledger and reconciliation experience under a Senior Accountant's review.
Payroll Specialists
Run payroll cycles and statutory filings against each jurisdiction's calendar.
Bookkeeper
Own day-to-day transaction coding and bank reconciliations, keeping the books current for month-end close.
Compliance Reviewers
Independently review VAT/tax filings and year-end accounts before anything reaches you for sign-off.
Client Services Coordinator
Coordinates scheduling, document requests and day-to-day communication so nothing falls through the cracks.
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.
Questions finance teams ask before they scope a call.
Direct answers now, so the discovery call starts from what's still unclear.
How do you keep our data secure?
Every engagement runs under a signed confidentiality agreement first, access is role-based to your named team only, and we work inside your own software rather than migrating your data anywhere else.
What happens if our main contact is unavailable?
You're never staffed by one freelancer. Each engagement has a named Engagement Lead plus Senior Accountants, Payroll Specialists, and Compliance Reviewers, so coverage doesn't depend on a single person.
Do we have to migrate to new software?
No. We work directly in Xero, QuickBooks, Sage, or FreeAgent. Whichever you already use.
How much of the working day do we actually overlap?
Our working hours are structured to overlap with UK, US, Canadian, and European business hours. See the live London, New York, Toronto, Paris and Dhaka times in the hero above.
What if our scope needs to change later?
Every engagement is reviewed on a regular cadence and adjusted as your business changes. Scope isn't fixed forever, just fixed and clear at any given time.
Which jurisdictions and software do you support?
UK, USA, Canada, and Europe for jurisdictions; Xero, QuickBooks, Sage, and FreeAgent for software.
