Back-office systems integration

Quick answer

Connecting accounting, HR and document systems so one dataset flows through without re-keying.

Key facts

Who it is for
Organisations running separate systems where departments hold conflicting data.
Authority involved
Private parties
How it differs
Unlike a full system replacement, this keeps existing systems and connects only the data that must flow.
Service areas
Bangkok, Khon Kaen, Udon Thani, Nong Khai and online nationwide

Document checklist

  • Inventory of systems and the owner of each dataset
  • Samples of required reports and their frequency
  • Access-control and retention requirements

Working steps

  1. Decide which system is the source of truth for each dataset
  2. Design the integrations and synchronisation rules
  3. Validate against a small set of real data
  4. Go live with error monitoring and a rollback plan

Cautions

  • Two-way sync without a source of truth tends to create silent conflicts
  • Plan error monitoring before, not after, go-live

AspectWith our teamDoing it yourself
ScopeConnecting accounting, HR and document systems so one dataset flows through without re-keying.Self-filing: you research the destination requirements, assemble the file and follow up at every counter yourself.
Authority to deal withHandled directly between the parties, coordinated end to end by one accountable contact.You approach each authority separately and carry the risk if the sequence is wrong.
Documents requiredChecked before work starts: Inventory of systems and the owner of each dataset · Samples of required reports and their frequency · Access-control and retention requirementsMissing items are typically discovered at the counter, forcing a re-file.
Common riskKnown failure points are checked upfront, e.g. two-way sync without a source of truth tends to create silent conflictsProblems surface only after rejection, which usually means restarting the process.
Which to chooseUnlike a full system replacement, this keeps existing systems and connects only the data that must flow.Reasonable when there is a single document, the destination states its requirements clearly, and no deadline is pressing.

Worked scenarios

First-time preparation

Situation: The requester falls within organisations running separate systems where departments hold conflicting data. and has never filed this type of matter, so it is unclear which file the receiving counterparty will accept.

Approach: Start by decide which system is the source of truth for each dataset, walk the checklist item by item before any work begins, then follow the sequence through to go live with error monitoring and a rollback plan.

Outcome: The result is a complete file at the first submission, avoiding repeat trips and retroactive corrections.

Previously rejected file

Situation: An earlier submission was returned; the most common cause in this type of work is two-way sync without a source of truth tends to create silent conflicts.

Approach: Trace back from the rejection point, fix the root cause, then re-check the second most common failure — plan error monitoring before, not after, go-live — before re-filing.

Outcome: The file can be re-filed without rebuilding it, with a written record of each correction for the authority.

Bundled with related work

Situation: Several matters within technology and organisational data governance are needed at once, and the same documents should not be submitted repeatedly.

Approach: Sequence the prerequisite item first, share one core document set, and split out only what each authority additionally requires.

Outcome: Fewer certified copies and fewer counter visits, while each individual file remains correct on its own.

How does back-office systems integration differ from document workflow digitisation, and should they be combined?

Connecting accounting, HR and document systems so one dataset flows through without re-keying. By contrast, designing the document path from intake and verification through approval and archiving, so every step is auditable and re-filing is reduced. Both sit in technology and organisational data governance and share base documents, so planning them together avoids duplicate filings when the destination requires both.

How does back-office systems integration differ from personal data protection (pdpa) programme, and should they be combined?

Connecting accounting, HR and document systems so one dataset flows through without re-keying. By contrast, policies, records of processing activities and consent forms aligned with the Personal Data Protection Act.
