ZTABS delivers custom integration development in Singapore — connecting SingPass/MyInfo, PayNow, TradeNet, and enterprise systems for fintech, government entities, and ASEAN-scale businesses.
Custom integration development in Singapore addresses the integration challenges unique to the Singapore business ecosystem — connecting with the government's advanced digital infrastructure (SingPass, MyInfo, CorpPass, PayNow, TradeNet, GoBusiness), integrating with Singapore's financial systems (FAST, PayNow, SGFinDex, GIRO), and bridging enterprise systems across ASEAN markets with varying integration capabilities. Singapore's integration landscape is characterised by: rich government API ecosystem (Singapore government operating one of the world's most connected digital platforms. SingPass (5.5M users) providing national digital identity authentication. MyInfo providing verified personal data with consent (130+ data fields from government sources — NRIC, address, income, CPF, property, vehicles). CorpPass providing business authentication and authorisation. GoBusiness licensing and permit applications. ACRA BizFile+ for company registration and filing. IRAS for tax computation and filing. CPF Board for employer contribution submission. TradeNet for customs declarations.
These government platforms each having different integration methods, authentication patterns, and data formats — creating a complex integration landscape that every Singapore business must navigate), financial system integration (Singapore's financial infrastructure being highly automated. FAST (Fast and Secure Transfers) processing real-time domestic transfers. PayNow enabling payments by NRIC, mobile number, or UEN (business registration number). GIRO handling recurring payments and collections. SGFinDex aggregating financial data across institutions. MAS API Register cataloguing 600+ financial APIs. Integrating with these systems requiring understanding of SWIFT messaging, ISO 20022 standards, and MAS TRM security requirements), multi-system enterprise complexity (Singapore enterprises operating complex system landscapes — SAP S/4HANA or Oracle for ERP, Salesforce or HubSpot for CRM, Workday or Talenox for HR, Xero or QuickBooks for accounting, and numerous vertical-specific systems.
These systems needing to exchange data reliably — customer data flowing from CRM to billing, employee data flowing from HR to payroll to CPF, financial data flowing from transactions to accounting to tax reporting), and ASEAN integration challenges (Singapore companies operating across ASEAN facing different integration landscapes in each country — Indonesia's tax system (DJP), Thailand's revenue department, Philippines' BIR each with different technical capabilities. Payment systems varying by country — PayNow in Singapore, PromptPay in Thailand, QRIS in Indonesia, InstaPay in Philippines. Building integrations that work across ASEAN while maintaining Singapore as the operational hub)).
Singapore's custom integration demand spans government system connections, financial operations, trade and logistics, and enterprise system orchestration. Government system integration: the most Singapore-specific integration category. SingPass/MyInfo integration: every customer-facing digital service in Singapore benefiting from SingPass authentication and MyInfo data. Banks — digital account opening with MyInfo eliminating form-filling and document upload. Insurance — policy application with verified personal data reducing underwriting time. Real estate — property rental applications with verified identity and income. Government vendors — all citizen-facing government services authenticating through SingPass. The integration: implementing OAuth 2.0/OIDC flow with SingPass, handling consent management, retrieving and caching MyInfo data, and maintaining the security standards SingPass requires. CorpPass integration: business-facing applications needing corporate authentication — B2B platforms, government procurement systems, and corporate banking. CorpPass handling multi-level authorisation (company admin granting different access levels to different employees). TradeNet integration: Singapore's customs platform — every import and export requiring TradeNet declarations.
Logistics companies, trading firms, and manufacturers integrating their order management and inventory systems with TradeNet for automated customs declaration filing. ACRA/IRAS integration: company registration verification (ACRA), tax filing (IRAS GST returns, corporate tax), and compliance reporting — automated through API integration rather than manual portal interaction. Financial operations integration: payment system integration: businesses needing to collect and disburse payments through multiple channels — PayNow (QR payments, transfer by NRIC/UEN), FAST (real-time bank transfers), GIRO (direct debit for recurring payments), credit/debit cards (Visa, Mastercard via payment gateways), and digital wallets (GrabPay, ShopeePay, DBS PayLah!). Each payment channel having different integration methods, settlement timelines, and reconciliation formats — a unified payment integration layer consolidating all channels for the business. Bank integration: multi-bank connectivity for cash management — balance enquiries, statement retrieval, payment initiation, and reconciliation across DBS, OCBC, UOB, and international banks.
SGFinDex integration: wealth management and financial planning platforms connecting to SGFinDex to aggregate customer financial data (bank accounts, insurance policies, investments, CPF) — with customer consent — providing unified financial views. Trade and logistics: TradeNet for customs. PSA (Port of Singapore Authority) systems for container tracking and port operations. Shipping line APIs (Maersk, MSC, CMA CGM) for vessel and container tracking. Freight management systems (CargoWise) connecting to multiple carriers and customs authorities. Supply chain visibility: integrating procurement, logistics, customs, warehousing, and delivery into a connected flow.
Our Singapore integration methodology connects government platforms, financial systems, and enterprise applications reliably. Integration assessment: mapping all systems that need to connect, their API capabilities (or lack thereof), data flows (what data moves where, how frequently, how critically), and regulatory requirements (MAS TRM for financial data, PDPA for personal data). Each integration point assessed for technical approach (API, file-based, event-driven, RPA), data transformation requirements, error handling needs, and monitoring requirements. Integration architecture: selecting the right pattern for each integration scenario. API gateway: Kong or AWS API Gateway managing all external API connections — centralising authentication, rate limiting, logging, and versioning. Internal APIs also routed through the gateway for consistent management. Event-driven integration: Apache Kafka or AWS EventBridge for real-time data flow between systems — when a customer payment is received, events trigger account update, receipt generation, and accounting entry simultaneously without point-to-point coupling.
File-based integration: for systems requiring file exchange (CPF submission files, bank GIRO batch files, some government systems) — automated file generation, secure transfer (SFTP), and processing confirmation. Webhook integration: for SaaS platforms (Salesforce, HubSpot, Xero) that support webhooks — real-time notification of changes enabling immediate downstream processing. Government API implementation: SingPass/MyInfo following the specific technical requirements — PKCE OAuth 2.0 flow, JWE/JWS for data encryption/signing, environment-specific certificates, and careful handling of the consent/data retrieval flow including edge cases (consent declined, partial data availability, session timeout). TradeNet following the specific message formats and submission protocols. IRAS/ACRA following their respective API specifications with appropriate authentication and data formatting.
Error handling and reliability: retry logic (transient failures retried with exponential backoff), dead letter queues (failed messages preserved for investigation, not lost), circuit breakers (protecting downstream systems from cascade failures), idempotency (ensuring that retried operations don't create duplicates — critical for financial transactions), and reconciliation (automated comparison between source and target systems verifying data consistency). Monitoring and alerting: real-time dashboards showing integration health — message volumes, success rates, error rates, latency. Critical failures alerting operations within minutes via SMS, WhatsApp, or Slack. Business-level monitoring: not just "is the integration running?" but "did all 2,340 CPF records process correctly this month?

A Singapore wealth management firm (MAS-licensed Capital Markets Services licence, managing SGD 2.8B AUM for 4,200 high-net-worth clients, 85 relationship managers) operated a client onboarding process that was manual, slow, and frustrating for both clients and relationship managers.
The onboarding process: a new client opening an investment account requiring 23 steps across 6 systems — CRM (Salesforce — where the RM recorded client interest and initial information), compliance screening (World-Check via Refinitiv — AML/CFT screening of client name against sanctions and PEP lists), KYC documentation (client providing NRIC/passport, proof of address, source of wealth declaration — uploaded as scanned documents to a document management system), suitability assessment (the RM completing a financial needs analysis questionnaire with the client — recorded in a separate suitability assessment tool), account creation (the operations team manually creating the client account in the portfolio management system — Avaloq), and custodian notification (notifying the custodian bank (DBS or OCBC) of the new account — via email with account opening documents attached). The problems: time to onboard (average 14 working days from initial client meeting to account ready for trading.
For high-net-worth clients accustomed to premium service — 14 days was unacceptably slow. Competitor firms with better digital infrastructure onboarding in 3-5 days — the firm losing potential clients during the lengthy process. An internal survey found 8% of prospective clients withdrew during onboarding, citing the time and document requirements), manual data entry (client information entered manually into each of the 6 systems — name, NRIC, address, contact details, employment, source of wealth — each system requiring slightly different formats. A single client onboarding requiring approximately 3.5 hours of operations team time for data entry across systems. Error rate: 12% of new accounts containing at least one data discrepancy between systems — name spelled differently, address format inconsistent, NRIC digit transposed), compliance screening delays (World-Check screening performed manually — the compliance analyst copying the client name into the World-Check portal, running the search, reviewing results, and documenting the outcome.
For common names generating many potential matches — the review taking hours. Screening not initiated until all KYC documents were received — adding sequential delay. The firm processing 35-50 new client onboardings monthly — each screening taking 45 minutes average), document handling (KYC documents: scanned/photographed by clients and emailed to the RM, who forwarded to the operations team, who uploaded to the document management system, who shared with the compliance team for review. Documents frequently: poor quality (blurry photos of NRIC), incomplete (missing pages of bank statements), or incorrect (outdated address proof). Each document issue requiring a round-trip to the client for correction — adding 3-5 days per issue), and MyInfo opportunity missed (the firm aware that MyInfo could provide verified client data — eliminating much of the form-filling and document submission.
But MyInfo integration had not been implemented because the IT team considered it complex (SingPass/MyInfo having specific technical requirements) and the business case had not been formally justified).
We designed and implemented an integrated digital onboarding platform over 12 weeks: MyInfo integration (weeks 1-5): eliminating manual data collection. SingPass authentication: the RM sending a secure onboarding link to the client via WhatsApp or email. The client clicking the link, authenticating with SingPass (using their existing SingPass credentials — no new account needed), and consenting to share MyInfo data. MyInfo data retrieval: 28 verified data fields automatically populated — full name (as registered with ICA), NRIC number, date of birth, nationality, residential address, email, phone, employment (employer name, occupation, industry), income (declared to IRAS — with client consent), CPF contribution history (indicating employment stability and income level), property ownership (HDB, private property — from SLA records), vehicles (from LTA), and education (from MOE/ICA records). Data validation: MyInfo data verified by government sources — no manual verification needed for these fields. The onboarding form: pre-filled with MyInfo data.
The client reviewing the pre-filled data, adding any information not available through MyInfo (source of wealth narrative, investment objectives, risk tolerance), and submitting. Total client effort: 8 minutes (vs 45 minutes for manual form-filling plus document gathering). Automated compliance screening (weeks 3-7): real-time screening integrated into onboarding flow. World-Check API integration: as soon as the client's name and identifying information are captured (from MyInfo), the compliance screening runs automatically — no manual copying into the World-Check portal. Screening running in parallel with the client completing the rest of the onboarding form. Results: immediate for clear cases (no matches — 72% of screenings). For potential matches: automated pre-filtering using NRIC, date of birth, and nationality to eliminate obvious false positives (reducing potential matches by 65%).
Remaining potential matches: routed to compliance analyst with pre-populated analysis template — the analyst reviewing and documenting the decision, not performing the initial search and filtering. PEP (Politically Exposed Person) screening: integrated into the same flow — PEP status from World-Check and supplementary sources checked automatically. Negative news screening: automated search of adverse media related to the client — results summarised for compliance review. Total compliance screening time: from 45 minutes to 5 minutes for clear cases, 15 minutes for cases requiring analyst review. System integration (weeks 4-10): connecting all 6 systems into a unified onboarding flow. Event-driven architecture: each onboarding step publishing events consumed by downstream systems.
When the client submits the onboarding form: Salesforce CRM automatically updated with verified client data (opportunity status changed, client record enriched with MyInfo data), compliance screening triggered automatically (results flowing back to the onboarding workflow), suitability assessment pre-populated with client financial data (income, assets, investment experience — from MyInfo and the onboarding form), document management system populated with the MyInfo verification record (replacing scanned document uploads for government-verified data), Avaloq account creation triggered automatically once compliance screening is cleared and suitability assessment is approved (account parameters derived from client data — no manual entry by operations team), and custodian bank notification sent automatically via API (DBS/OCBC — structured message with account opening details). The RM: seeing a single dashboard showing onboarding progress across all systems — which steps are complete, which are pending, and what (if anything) requires their action. Suitability and risk profiling (weeks 6-10): integrated assessment.
The financial needs analysis questionnaire: presented to the client digitally (responsive web form — works on mobile). Client financial data from MyInfo pre-populating relevant sections (income, assets, CPF). The RM adding professional observations and recommendations during the client meeting (tablet-based — the RM completing the assessment while sitting with the client). Risk profiling: automated scoring based on questionnaire responses — Conservative, Balanced, Growth, Aggressive — with the algorithm documented and validated per MAS FAA requirements. Product suitability: the system recommending suitable products based on risk profile, investment horizon, and stated objectives — the RM reviewing and adjusting recommendations before presenting to the client. Digital signature: the client electronically signing the account agreement, suitability declaration, and FATCA/CRS declarations — DocuSign integration with the onboarding flow.
The platform launched after 12 weeks. Onboarding time: from 14 working days to 1.5 working days (89% reduction). Breakdown: client form completion from 45 minutes to 8 minutes (MyInfo pre-fill). Compliance screening from 45 minutes to 5 minutes (automated, parallel processing). Operations data entry from 3.5 hours to 15 minutes (automated system population — operations team only reviewing edge cases). Suitability assessment from 2 days (scheduling, paper form, transcription) to same-day (digital form completed during RM meeting). Account creation from 3 days (manual Avaloq entry, custodian notification) to 4 hours (automated once compliance and suitability cleared). Client experience: prospective client withdrawal rate from 8% to 1.5% (the faster process retaining clients who previously dropped off). Client satisfaction survey (post-onboarding): 4.7/5 — with MyInfo and digital signing cited as the most appreciated features.
RM comment: "Clients are impressed that we know their information already from MyInfo — it feels premium and modern, not like filling government forms." Data accuracy: data discrepancies between systems from 12% to 0.8% (MyInfo providing single-source verified data, automated population eliminating transcription errors). The remaining 0.8%: edge cases where manual data entry was still required for non-MyInfo fields. Compliance efficiency: compliance screening time from 45 minutes to 5 minutes per client (clear cases). False positive reduction: 65% fewer analyst reviews needed (automated NRIC/DOB matching eliminating obvious non-matches). Compliance team capacity: from processing 35-50 screenings monthly (fully loaded) to handling the same volume in 40% of the time — freed capacity used for enhanced monitoring of existing clients. Operations efficiency: operations team onboarding effort from 3.5 hours per client to 15 minutes — a 93% reduction.
The 3-person onboarding operations team: reduced to 1 dedicated plus 1 backup — 2 staff redeployed to client service roles. Monthly operations cost saving: SGD 18,000 (staff redeployment). Business impact: the accelerated onboarding directly impacting revenue — faster onboarding meant faster time-to-first-investment. Average time from onboarding start to first trade: from 21 days to 4 days. The firm estimating that faster onboarding contributed to 15 additional client acquisitions in the first 6 months (clients who would have been lost during the 14-day process). Average AUM per new client: SGD 1.8M. Management fee: 0.8% annually. 15 additional clients × SGD 1.8M × 0.8% = SGD 216,000 additional annual revenue. Financial summary: implementation cost: SGD 280,000. Annual operations savings: SGD 216,000. Additional annual revenue: SGD 216,000. First-year ROI: 54% (operations savings alone). Including revenue impact: 154%.
Compounding: each subsequent year adding new clients at the accelerated rate — the revenue impact growing annually.
