How does ml-connector handle TallyPrime's local-only HTTP server?

ml-connector runs a local agent on the same LAN as TallyPrime that polls the port 9000 HTTP endpoint for changes. The agent bridges the network gap between your cloud infrastructure and the desktop application, allowing ml-connector to read and write vouchers and ledger entries on a regular schedule.

Which direction does data move between TallyPrime and Deel?

The main flow is Deel into TallyPrime. Contractor invoices and payroll allocations move from Deel into TallyPrime as purchase and journal vouchers, mapped to your existing ledger groups. Employee and contractor records sync via Deel webhooks to validate ledger accounts. TallyPrime payment data can flow back to Deel as payroll input adjustments where needed.

How are Deel invoices and payroll allocations mapped to TallyPrime?

ml-connector maps Deel invoice amounts to TallyPrime ledger group codes that you pre-establish in your chart of accounts. Payroll allocations are split by cost category and posted to the matching expense groups. If a ledger group does not exist, the post fails and is logged for correction, then can be replayed once the group is created.

TallyPrime and Deel integration

TallyPrime manages your books and inventory across India and Southeast Asia. Deel handles global contractor and payroll operations. Connecting the two keeps your ledgers updated with contractor expenses and payroll allocations without manual re-entry. Contractor invoice amounts flow from Deel into TallyPrime purchase vouchers, and employee cost breakdowns post to the correct ledger groups. ml-connector bridges the local desktop nature of TallyPrime with Deel's cloud-based payroll infrastructure.

How TallyPrime works

TallyPrime is a desktop-first accounting and ERP application that stores vouchers, ledgers, groups, and stock items on a local Windows machine. It exposes data through an XML or JSON HTTP API at http://<tally-host-ip>:9000 via a single endpoint controlled by TALLYREQUEST envelopes. The port 9000 server must be manually enabled in TallyPrime Settings and is only LAN-accessible, requiring a local agent bridge from the cloud. Authentication is optional at the transport layer; network security and optional company credentials are managed via the envelope. TallyPrime has no native webhooks or event subscriptions, so polling is the only option, typically on 5- to 15-minute intervals. Concurrent requests can cause inconsistent behavior, and the application must be running with the target company open for API calls to succeed.

How Deel works

Deel is a global workforce platform exposing contracts, employees, invoices, payslips, and payroll inputs through a REST API at https://api.letsdeel.com/rest/v2. Authentication uses bearer tokens (organization or personal) or OAuth2 with a 30-day access token expiry and 90-day refresh token expiry. Deel supports webhooks for real-time events such as contract creation, employee updates, and terminations, with HMAC-SHA256 signature verification. API tokens are fine-grained scoped at creation time, and the API enforces rate limits with HTTP 429 responses. Deel is payroll and HRIS only; it does not expose vendor masters, purchase orders, or items. Pagination is offset-based with a default limit of 25. Idempotency-Key headers are supported for POST and PATCH calls to prevent duplicate submissions.

What moves between them

The integration runs in two directions. Deel contractor invoices and employee payroll allocations flow into TallyPrime as purchase and journal vouchers, posted to the appropriate ledger groups on a daily or weekly schedule. Employee and contractor data from Deel webhooks triggers ledger account validations in TallyPrime so cost allocations land on existing groups. TallyPrime payment vouchers and adjustments are polled and can flow back to Deel as payroll input adjustments or deductions where needed. The main cadence is tied to your payroll and contractor payment schedule.

How ml-connector handles it

ml-connector runs a local agent on the same LAN as TallyPrime that polls the port 9000 HTTP endpoint for changes to vouchers and ledger entries using date-range filters and comparing returned IDs against the last-seen state. On the Deel side, it receives webhooks for contract and employee events, verifies the HMAC-SHA256 signature, and queues the invoice or payroll data for posting into TallyPrime. To avoid duplicate vouchers, ml-connector tracks VoucherNumber in TallyPrime and uses an idempotency approach on Deel POST calls. TallyPrime's company name and optional credentials are stored encrypted. The local agent bridges the network gap, and polling intervals are conservative to respect TallyPrime's single-user design. When Deel invoices or payroll allocations arrive, ml-connector maps them to TallyPrime ledger group codes already established in your chart of accounts. Errors from the TallyPrime XML response are captured and audited; failed posts can be replayed once the underlying issue is resolved.

A real-world example

A mid-market services company operates across India and the Philippines, using TallyPrime for accounting and GST compliance and Deel for global contractor payroll. Before the integration, the finance team received Deel invoices and payroll reports weekly, manually entered each contractor payment and payroll tax allocation into TallyPrime as separate purchase vouchers, and spent days reconciling ledger balances during month-end close. With TallyPrime and Deel connected, Deel contractor invoices automatically post as TallyPrime purchase vouchers on the due date, and payroll allocations flow into the correct expense groups. The finance team spends half the time on data entry and achieves close in 40 percent fewer days.

What you can do

Post Deel contractor invoices into TallyPrime as purchase vouchers, mapped to the correct ledger groups.
Sync employee and contractor data from Deel to TallyPrime via webhooks and reconcile against active ledger accounts.
Allocate Deel payroll costs to TallyPrime expense groups on your payroll schedule without manual re-entry.
Bridge TallyPrime's local port 9000 server to the cloud, polling on intervals that respect single-user design constraints.
Track all invoice and payroll posts with a full audit trail; replay failed entries once corrections are made.
