Your store and your back office,finally in sync.
Orders in Shopify, invoices in Tally, stock in a warehouse system, customers on WhatsApp. When those disagree, people fix it by hand every day. We build the integrations that keep them agreeing, with retries, logs and alerts when something breaks.

In short
Byteinfy connects Shopify to the systems around it from $1,500: ERPs and accounting (Tally, Zoho, myBillPlease), WhatsApp, shipping and 3PL partners, CRMs and marketplaces, as reliable custom apps rather than fragile spreadsheets.
Last updated 5 September 2026 · Written by the Byteinfy team, which builds and operates SwipeReel and myBillPlease.
Who it is for
- Brands reconciling Shopify orders into accounting by hand
- Stores with stock in an ERP or a 3PL that drifts from Shopify
- Teams sending order updates on WhatsApp manually
- Marketplaces and multi-channel sellers syncing catalogues
What you get
- Custom Shopify app with webhooks, queues and idempotent sync
- Connectors for accounting (Tally, Zoho Books, myBillPlease), shipping (Shiprocket, Delhivery, 3PLs), messaging (WhatsApp Business API) and CRMs
- Mapping documents and a reconciliation report you can run any day
- Monitoring with alerts to Slack or email when a sync fails
How it works
- 1
Map
Every field, every direction, every edge case (refunds, partials, returns) on one diagram.
- 2
Build
Sync in shadow mode first; you compare both systems before it writes anything.
- 3
Run
Alerts, logs and a monthly reconciliation until you trust it, then a retainer if you want one.
Pricing
From $1,500
A single integration (orders to accounting, inventory from an ERP) is $1,500 to $4,000. Multi-system programmes are quoted on a diagram we draw together.
Questions we get asked
- Can you integrate GST invoicing?
- Yes. We build and operate myBillPlease, so GST invoices, e-invoices and credit notes from Shopify orders are a first-class integration.
- What if the other system has no API?
- We work with exports, SFTP drops or email parsing when we must, and tell you the reliability trade-off up front.
