How Calxa Unlocked 3 New ERP Markets Without Hiring a Single ERP DeveloperIndustry IndustryFinancial reporting & forecasting (Fintech SaaS)The ClientCalxa is a leading budgeting and cashflow forecasting platform used by SMEs, accountants, and not-for-profits across Australia and New Zealand.Historically, Calxa relied on QuickBooks Online and Xero integrations to win customers. However, the market began shifting especially in Australia, where: Xero holds strong market share Larger organisations increasingly adopt Microsoft Dynamics 365 Business Central, MYOB Acumatica, and NetSuite And this segment faces complex reporting, multi-entity, and multi-currency challenges exactly the space where Calxa thrivesTo grow, Calxa needed to support these mid-market ERPs.To execute, they needed deep ERP expertise and fast.The ChallengeCalxa’s engineering team had strong experience with SME accounting products but faced several major hurdles:1. Complex ERP landscape they were not familiar withMicrosoft Business Central, MYOB Acumatica, and NetSuite have: Multiple entities (holding + subsidiaries) Multi-currency ledgers Customised charts of accounts Heavy API variations (REST, SOAP, OData, SuiteQL) Client-specific customisationsCalxa’s team did not have the knowledge to build robust, production-grade integrations for all three.2. High entry barriersSome ERPs require formal certification before API access.For example: MYOB Acumatica requires API Developer Certification from Acumatica Academy.This meant extra time, training, and cost without guarantee of success.3. Building integrations internally was impracticalInternal development would require: Learning 3 large ERPs Understanding 3× authentication models Managing 3× rate limits & token expiry flows Writing 3× sync engines Creating 3× error-handling & retry mechanisms Writing 3× test suites Extensive QA cyclesEstimated internal effort if built in Australia:~2,500–3,000+ hours, costing AUD $350,000+, with a 9–12 month timeline.4. Product demanded a unified experienceCalxa wanted: One unified API layer One unified data model Identical response formats regardless of ERP One codebase for their internal platformThat required architectural thinking beyond writing connectors.5. Third-party unified API products were not suitableAPIs like Merge.dev, Codat, or Unified.to provide generic connectors but not: Solution design Data modelling Handling multi-entity ERP complexity Custom reporting logic Deep testing across edge cases Consulting on authentication, retry cycles, or rate-limit governanceUsing them would still require Calxa’s team to: Build significant custom logic Handle reporting transformations Map multi-entity structures Maintain the integration long-term And pay USD $500–2000/month per connectorThis would cost more and deliver less.Calxa needed a true integration partner, not an API aggregator.Our ApproachSatva Solutions took full ownership strategically and technically.1. Discovery WorkshopWe studied: Calxa’s existing Xero + QBO integrations Their data model Their forecasting engine How budgets, actuals, and categories flow Reporting logic and internal architectureThis helped us blueprint an ERP-agnostic integration model.2. Designing a Unified Integration PlatformWe translated all requirements into a single architecture: One unified API for Calxa One common data format One unified sync pipeline Controlled token management Automatic retry logic ERP-specific adapters behind the scenesThis ensured Calxa’s product team never deals with ERP complexity again.3. Building Three Deep ERP IntegrationsWe developed full-scale connectors for: Microsoft Dynamics 365 Business Central (REST + OData) MYOB Acumatica (REST + certified API access) NetSuite (Token-based auth + SuiteQL + saved searches)Key features: Full chart of account syncing Multi-entity hierarchy mapping Multi-currency balances Budget & Actuals extraction Category mapping to Calxa structure Rate limit protection Token lifecycle management Automatic restart + retry on failure4. Rigorous End-to-End TestingWe performed: Multi-company test runs Multi-currency validations Customised ERP tenant test cases Failure scenario + timeout testing Load testing for large datasets Edge-case testing for entity hierarchiesThis ensured reliability across diverse customer environments.The Results1. Massive Engineering Time SavedCalxa avoided: ~2,500–3,000 hours of internal development 9–12 months of R&D AUD $350,000+ in internal costSatva delivered all three integrations in a fraction of the time.2. Zero need for ERP trainingCalxa’s engineering team did not need to learn: OData SuiteQL ERP authentication flows Token renewal ERP entity hierarchies ERP customisation modelsIt eliminated long learning curves and avoided hiring ERP specialists.3. QA and Test Coverage Fully OffloadedCalxa’s QA team did not need to: Understand 3 ERPs Build test cases Learn API quirks Manage ERP sandbox/test dataOur team handled 100% of test coverage.4. Avoided recurring cost of third-party unified API vendorsUsing Codat/Merge would require: USD $500–2,000 per ERP per month Still needing custom logic No consulting or solution design Limited flexibility with custom ERP tenants No help for complex reporting & forecasting structuresWith Satva: Zero recurring connector fees Full ownership of code Full flexibility Fully tailored architecture5. New Revenue Opportunities for CalxaCalxa can now target: Larger SMEs Mid-market enterprises Multi-entity groups NFPs using Business Central, NetSuite, and AcumaticaThis opens up hundreds of potential customers previously not addressable.6. Competitive AdvantageCompared to other budgeting/forecasting tools, Calxa now offers: Support for 5 major accounting/ERP systems Enterprise-grade integration reliability Unified API for forecasting Faster onboarding of complex organisationsThis gives Calxa a significant edge in AU/NZ and global markets.ConclusionCalxa was ready to scale beyond SME accounting tools but lacked the ERP expertise to do it themselves.Satva Solutions delivered: A unified ERP integration platform Three enterprise-grade connectors Robust authentication & token management Multi-entity, multi-currency reporting sync Fully designed, tested, and production-ready architectureThis engagement saved large engineering and QA effort, avoided costly third-party API subscriptions, and unlocked new revenue streams helping Calxa compete strongly in the mid-market ERP space.Calxa now serves a much wider audience while keeping its internal teams focused on what they do best: building world-class budgeting and forecasting tools.Technology Stack Asp.Net MVC API with .NET Framework 4.8 View All Case Studies
