ERP Implementation

API and system integration services for connected records

Our API and system integration services connect Tally, SAP, Salesforce and internal software. We define field mapping, validation, error handling and transfer logs so your team can check where each record went.

The starting point

When the same record has to be entered twice

The same customer exists three times with three different spellings.

Each system created its own record because nothing decides which one is authoritative.

Finance and sales report different revenue for the same month.

Two systems hold overlapping data and sync on different schedules, so both are right at different moments.

Our accounting is in Tally and nothing else can see it.

Tally holds the numbers the business is run on, and it sits outside every other system in the company.

What the work includes

Reliable transfers with clear ownership and validation

We agree which system owns each field and what a successful transfer requires. The connection handles transformation, validation and recovery, with logs that help the team identify and resolve missing or rejected records. Access and sync frequency are matched to the systems involved.

Source of truth mapping

Which system owns the customer, the price, the stock figure. Agreed before any code, because two systems both believing they own a field is the root of most sync problems.

API development

REST and GraphQL endpoints for your systems, and SOAP where an older enterprise product requires it.

Tally, SAP and Salesforce connections

Transactions synced into and out of the systems your finance and sales teams already live in, without asking them to move.

Transformation and validation

Field mapping, format conversion and validation rules, so bad data is caught at the boundary rather than spread.

Error handling and retry

Failed transfers can be queued, retried and reported, with logs that identify the affected record and the reason for failure.

Legacy connection options

Assess supported database access, scheduled file exchange or interface automation when a system has no suitable API. Confirm permissions and maintenance requirements before choosing the connection.

Make ownership and recovery explicit

An invoice number, customer identifier or currency value must mean the same thing in both systems. Agree the field map, the source of authority and the checks required before a transfer is accepted. Repeated requests and simultaneous edits need defined handling.

A failed connection should leave enough information to identify the affected record and retry safely. Sync frequency follows the business need and the limits of each system. These decisions belong alongside the ERP implementation when departments share operational data.

Connect checked information to the destination record

If AI-enabled document capture supplies the input, decide which fields need review before the transfer proceeds. The destination may reject an unknown supplier, a missing amount or a duplicate reference. The reviewer needs a clear way to correct the record and resume the process.

Business process automation connects that document handling, validation and exception workflow to the integration.

Build the connections an AI-enabled workflow can use

Our engineers define the operations an application can expose to an AI-enabled workflow. Tool calling lets a model request one of those operations, such as a customer lookup or a draft record. We build the validation and permission checks around that request before it runs, keeping the connection tied to an explicit business action.

Define which tools are available, the fields each accepts and the actions that need approval. Logs should identify the request, result and any failure without collecting unnecessary sensitive content. These integration guardrails support AI-enabled automation systems by giving model-assisted steps a controlled route into existing software.

Choose the connection the source system can support

API integration suits systems that expose the required records and actions with supported access. Scheduled file exchange can fit a batch handoff when immediate updates are unnecessary. Where neither is available, assess interface automation and the maintenance it will require. The system version, available permissions and transfer limits shape the choice.

For a Tally integration, bring the product version, an example invoice or ledger record, and the system that will send or receive it. Define how to recognise an existing record, reconcile totals and resume after a failed transfer before deciding the sync schedule.

Discuss your requirements

01Discovery
We walk your current workflow with the people who run it and record where work stalls, duplicates or waits.
02Scope and quote
A fixed price and a dated plan, issued after discovery. Payment runs against milestones.
03Design
Review the proposed workflow, interfaces and data requirements before implementation. The design work follows the scope of the project.
04Build and review
Implement the agreed scope in short cycles, review the changes and test the behaviour with representative records and exceptions.
05Integrate and release
Test the required connections, confirm acceptance with your team and release according to the agreed rollout plan.
06Support
The team that built it handles updates, integrations and support calls after go-live.

How we can work together

Projects here typically run between USD 7,500 and USD 15,000 or above, depending on scope. We quote a fixed price after discovery and bill against milestones.

Fixed price

Fits when: Scope is clear and agreed after discovery

Billing: Milestone payments against a dated plan

Dedicated team

Fits when: Scope will evolve, and you want capacity reserved

Billing: Monthly, per named engineer

Support retainer

Fits when: The system is live and needs changes and cover

Billing: Monthly, with an agreed response window

Questions about Integration Services

Can you integrate with Tally?

Yes. Tally is one of the most common integrations we build in this market, usually syncing invoices, payments and ledger entries between Tally and an operational system. Finance keeps working the way it already does, which removes the biggest objection to any change.

What if the system we need to connect has no API?

There are still options. Database-level integration where access is available, scheduled file exchange where it is not, and interface-level automation as a last resort. We tell you which one applies and what it costs to maintain before committing.

How often does data sync?

It depends on the field. Stock levels and order status usually need near real time. Master data such as a customer list is often fine hourly or nightly. Syncing everything constantly costs more and creates load nobody needed.

What happens when two systems change the same record at once?

The source of truth decided during mapping wins, and the other change is logged as a conflict rather than silently discarded. Conflicts that recur are usually telling you the ownership decision was wrong, which is worth knowing.

How do we check that a sync completed?

Every transfer writes a log entry with a timestamp, record count and outcome, and failures raise an alert rather than waiting to be noticed. Integration without observability is the reason people stop trusting integrated data.
