Zoho Integration

Yes, and it is the request we get most often — usually because the accountant is not moving off Tally and does not need to. The pattern that works is one-directional: invoices and bills raised in Zoho Books flow into Tally, which stays the statutory filing record. What we generally advise against is two-way sync between two accounting systems, because it means two places can edit the same financial fact and reconciling that disagreement costs more than the integration saves.

Overwhelmingly one cause: the connection was authorised under an individual's account, that person left, their account was deactivated, and the sync stopped. Nobody noticed because integrations fail silently — the data simply stops arriving. The prevention is trivial and almost never done: authorise under a service account owned by the company, and make failures surface somewhere a named person actually looks.

Check the connector first, always. Zoho has native integrations for a great many common systems, and Zoho Flow covers a lot of the rest without code. Custom development is genuinely needed for internal software, older ERPs and anything with an unusual API — but writing code to do something a supported connector already does correctly is a maintenance liability chosen for no reason, and we will tell you when that is what you are about to buy.

Yes, through the WhatsApp Business API. Enquiries arrive as records with the conversation attached, and invoices, updates and reminders go out from the system. The constraint worth knowing before you plan around it is that outbound message templates need provider approval, so the wording of automated messages is not entirely yours to decide and changes take time. Inbound and reply-within-the-window messages are not restricted the same way.

Less often than people assume. Real-time costs more, is harder to debug, and fails harder when the other end is unavailable. A scheduled sync every fifteen minutes serves most requirements, recovers from outages far more gracefully, and is considerably easier to reason about at two in the morning. Genuine real-time is worth it where a human is waiting on the result — a payment confirmation, a stock check at the point of sale.

That is a design decision rather than an accident, and we settle it before building. Either the integration tracks what it has processed and catches up on its own when the other side returns, or there is a documented way for somebody to re-run a window. What must not happen is the silent gap — records that were never synced, never flagged, and discovered at month-end when the totals do not agree.

When the volume is small enough that it will not repay the build and the maintenance; when the same few people use both systems and would rather copy a handful of records than depend on something they cannot fix themselves; when one side is being replaced within the year; or when the process is still changing monthly, because automating an unsettled process hardens the wrong version of it. We would rather say this than sell the work.

You do. Custom functions, Flow configurations and any API code we write for you are documented and handed over, along with where errors surface and how to re-run a failed window. An integration only you cannot explain or modify is a dependency rather than an asset, and it is the thing businesses most regret when a partner relationship ends.
