On-device inference uses Apple Core ML 7, Google ML Kit, ONNX Runtime Mobile, or MLC LLM for sub-2B-parameter models. Cloud inference defaults to OpenAI, Anthropic, or AWS Bedrock; streaming responses require server-sent events (SSE) handling that most RN libraries get wrong. AI mobile devs need ML literacy (model size vs latency vs accuracy trade-offs), prompt engineering for production reliability, and observability (token spend per session, P95 latency). A "mobile dev who used the OpenAI SDK once" cannot ship reliable AI features at scale.
We understand the unique demands of the accounting, tax preparation, and cpa firm technology industry and build solutions that address them head-on. With a market size of $20B global accounting software market, projected $28B by 2028, the accounting & cpa firms sector demands technology partners who truly understand the industry.
US tax code spans 70,000+ pages with federal, state, and local requirements. CPA firms need software that handles multi-entity, multi-state filing, automatic form selection, and real-time regulatory updates — with zero tolerance for calculation errors. For AI-first mobile app development engagements, addressing this at the architecture level from day one keeps it from compounding later.
CPA firms exchange thousands of sensitive documents with clients annually. They need secure portals for document upload, e-signatures, messaging, and deadline tracking that are intuitive enough for non-technical clients while maintaining SOC 2 compliance. For AI-first mobile app development engagements, addressing this at the architecture level from day one keeps it from compounding later.
Tax season creates extreme workload peaks. Firms need tools that automate preparation workflows, track engagement status across hundreds of clients, manage review processes, and forecast capacity to avoid missed deadlines and staff burnout. For AI-first mobile app development engagements, addressing this at the architecture level from day one keeps it from compounding later.
Firms must connect with QuickBooks, Xero, Sage, FreshBooks, and dozens of other platforms their clients use. Each integration requires real-time data sync, reconciliation logic, and handling of different chart-of-accounts structures. For AI-first mobile app development engagements, addressing this at the architecture level from day one keeps it from compounding later.
