ERP Integration: Connecting Tally, CRM, APIs and Machines

An ERP is most useful when data flows into it and out of it without anyone retyping. ERP integration connects the ERP with the other systems you use, from accounting and CRM to e-commerce, banks and machines on the shop floor.

What is ERP integration?

ERP integration means connecting your ERP with other software so that data moves between them automatically. A sales invoice raised in the ERP appears in your accounting software; an order from your website becomes a sales order; output counted by a machine updates the job card.

Without integration, people bridge the gap by exporting, retyping and reconciling, which is slow and introduces errors.

Common ERP integrations for Indian businesses

Connect toWhat flows
Accounting software (for example Tally)Masters, sales and purchase invoices, payments, receipts, journals
CRMCustomers, quotations, won deals becoming sales orders
E-commerce and marketplacesOnline orders, stock levels, dispatch status
BanksStatements for reconciliation, payment files
Biometric devicesAttendance punches into HR and payroll
Machines and sensorsCounts, running time and downtime into production
MessagingWhatsApp or email alerts and documents to customers

Ways to integrate an ERP

  • Built in: the best integration is not needing one. When CRM, sales, stock and accounts are modules of the same ERP, they already share data.
  • Ready connectors: a supported connector for a common system, such as accounting software, maintained by the vendor.
  • APIs: a documented REST API lets your developers or a partner connect other systems in real time.
  • File import and export: CSV or Excel for occasional loads, such as price lists or bank statements.
  • Integration platforms (iPaaS): tools that connect many apps, useful when you run several cloud services.

Checklist for planning an integration

  1. Pick one system to own each record. Customers might live in the ERP and flow to accounting, never the other way round.
  2. List the data that moves, in which direction, and how often: real time, hourly or daily.
  3. Match the masters (ledgers, items, tax codes) before turning on the sync.
  4. Decide what happens on errors, and who is told when a record fails.
  5. Test with a month of real data before switching off the manual process.

Integrations in DotOne

DotOne keeps CRM, sales, purchase, inventory, production, quality, accounts, HR and payroll in one system, so most data never needs an integration. For accounting, the Tally connector syncs masters and vouchers both ways with Tally Prime, and sync with Busy and Zoho Books is also available. Bank statements can be imported for bank reconciliation, biometric devices feed attendance, and the REST API connects other systems.

Frequently asked questions

What is ERP integration?

Connecting an ERP with other software, such as accounting, CRM, e-commerce, banks or machines, so data moves between them automatically instead of being retyped.

What is CRM and ERP integration?

Linking customer and deal data in a CRM with orders, stock and invoices in the ERP. If the CRM is a module of the ERP, they already share the same data.

How do you integrate an ERP with Tally?

With a connector that syncs masters such as ledgers and items, and vouchers such as sales, purchases, payments and receipts. DotOne has a two-way Tally connector.

What is an ERP API?

A documented interface that lets other software read and write ERP data securely, so developers can build real-time integrations. See the DotOne API reference.

What should we integrate first?

Accounting, if your books are in another system, because every sale and purchase affects them. Then the system that creates the most manual retyping.
