Incomplete records, an inapplicable rule or delayed approval can affect filing and tax payments. The issues below are review points for defining an engagement, not reports of any client's results.
Mismatched opening balances corrupt the full-year statements and force audit adjustments.
How we prevent it: Agree the parallel-testing period and reconciliation scope before cut-over, checking opening balances, file completeness and records that cannot be migrated.
No audit trail means fraud cannot be traced afterwards.
How we prevent it: Configure role-based access and check audit-log availability, recording limitations and who reviews the logs.
High annual licence and consulting cost for features you use less than half of.
How we prevent it: We size from real transaction and user counts and present two options with a three-year cost.

Compare your options
| Aspect | Do it yourself | In-house staff | Work with us |
|---|---|---|---|
| Total annual cost | Looks free, but costs the owner's time and carries penalty risk | Assess actual payroll, employer contributions, software and cover arrangements rather than assuming one annual cost | Request a staff quotation that identifies scope and any additional items before agreement |
| Continuity | Stops the moment the owner gets busy | Staff turnover takes the institutional knowledge with them | Agree engagement owners, handover arrangements and traceable document storage |
| Review layer | Nobody double-checks | Self-review only, rarely an outside perspective | Preparer and reviewer within scope; audit work separately assigned to a CPA Partner (system setup) |
| When the Revenue Department calls | You attend and answer alone | In-house staff rarely have hearing experience | Prepare evidence and explanations within scope; attendance depends on authorization and taxpayer duties |
An adviser, not just a filer
Start with an initial discussion for a quotation, then agree topics, contact channels and follow-up frequency in writing. Additional work requires prior agreement; unlimited advice is not automatically included.

FAQ
PEAK suits Thai SMEs that need every Thai tax feature. Xero suits companies with cross-border, multi-currency operations.
Yes — full data migration including open balances and historical vouchers.
It suggests accounts from past postings, but accuracy varies by business; the bookkeeper still checks the supporting document for every line.
Look at document volume, inventory/costing needs, concurrent users, and e-Tax integration. We pilot with the client's real data before deciding.
We migrate in stages: opening balances, one month of parallel running, then cut-over — opening balances are reconciled to last year's statements before go-live.
Yes. We set role-based permissions, your team captures documents, and we review, close, and coach the team throughout the engagement.
