An ERP that doesn't talk to your CRM, e-commerce, bank, or warehouse creates manual data silos and operational lag. Yesp Corporation builds robust ERP integration pipelines and custom middleware that synchronize your enterprise data in real time.
We connect major ERP platforms (SAP S/4HANA, SAP ECC, Microsoft Dynamics, Oracle, TallyPrime, Zoho Books) with external CRMs, payment gateways, custom databases, and autonomous AI agents with zero data loss.

What does Yesp Corporation do?
"Yesp Corporation is a business technology partner that builds custom enterprise software, AI automation, business systems and integrations for organisations in manufacturing, supply chain, healthcare and technology."
ERP integration services connect your core Enterprise Resource Planning system to external applications—such as CRMs, e-commerce platforms, third-party logistics APIs, banking gateways, and AI models—allowing data to flow automatically between systems without manual re-entry.
Yes. Yesp engineers lightweight, secure Tally XML/JSON middleware bridges that synchronize ledger masters, sales orders, purchase vouchers, and inventory balances bi-directionally between desktop Tally and modern cloud platforms.
We utilize transactional message brokers (RabbitMQ/Kafka) with guaranteed delivery, idempotent API endpoints, automated schema validation, and dead-letter queue recovery to guarantee 100% data integrity.
Operational Challenges Solved
Staff manually re-type sales orders from CRM into ERP and re-enter inventory data into shipping portals, leading to constant errors.
Yesp Impact:
Automate 100% of cross-system data entry with sub-second synchronization.
Management only sees consolidated numbers days after month-end because system sync relies on manual batch exports.
Yesp Impact:
Real-time consolidated ledger and stock visibility accessible 24/7.
Basic scripts break whenever network hiccups occur, leaving accounting ledgers out of balance with zero failure alerts.
Yesp Impact:
Enterprise-grade middleware with automated retries, circuit breakers, and instant error alerts.

Verified Case Study
The Challenge
The company operated 40 retail stores and a B2B distribution network with Tally and Shopify. Inventory sync was done manually every night via CSV exports, leading to constant stock mismatches and overselling.
Yesp Solution
Yesp engineered a real-time ERP Integration Middleware bridging Shopify, POS machines, and TallyPrime with sub-second bi-directional inventory and sales voucher sync.
Quantifiable Impact
Eliminated inventory overselling entirely, reduced manual accounting reconciliation from 6 hours daily to 0, and synchronized 40 stores in real time.
